    Postoperative mortality 90 days after robot-assisted laparoscopic prostatectomy and retropubic radical prostatectomy: a nationwide population-based study2016Inngår i: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 118, nr 2, s. 302-306Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective To assess 90-day postoperative mortality after robot-assisted laparoscopic radical prostatectomy (RARP) and retropubic radical prostatectomy (RRP) using nationwide population-based registry data. Patients and Methods We conducted a cohort study using the National Prostate Cancer Register of Sweden, including 22 344 men with localized prostate cancer of clinical stage T1-T3, whose prostate-specific antigen levels were <50 mu g/mL and who had undergone primary radical prostatectomy in the period 1998-2012. Vital status was ascertained through the Total Population Register. The rates for 90-day postoperative mortality were analysed using logistic regression analysis, and comparisons of 90-day mortality with the background population were made using standardized mortality ratios (SMRs). Results Of the 14 820 men who underwent RRP, 29 (0.20%) died, and of the 7 524 men who underwent RARP, 10 (0.13%) died. Mortality in the cohort during the 90-day postoperative period was lower than in an age-matched background population: SMR 0.57 (95% confidence interval [CI] 0.39-0.75). There was no statistically significant difference in 90-day mortality according to surgical method: RARP vs RRP odds ratio (OR) 1.14; 95% CI 0.46-2.81. Postoperative 90-day mortality decreased over time: 2008-2012 vs 1998-2007 OR 0.44; 95% CI 0.21-0.95, mainly because of lower mortality after RARP. Conclusion The 90-day postoperative mortality rates were low after RARP and RRP and there was no statistically significant difference between the methods. Given the long life expectancy among men with low-and intermediate-risk prostate cancer, very low postoperative mortality is a prerequisite for RP, which was fulfilled by both RRP and RARP. The selection of healthy men for RP is highlighted by the lower 90-day mortality after RP compared with the background population.

    Metabolic syndrome and breast cancer in the me-can (metabolic syndrome and cancer) project.2010Inngår i: Cancer Epidemiology, Biomarkers and Prevention, ISSN 1055-9965, E-ISSN 1538-7755, Vol. 19, nr 7, s. 1737-1745Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Few studies have assessed the metabolic syndrome (MetS) as an entity in relation to breast cancer risk, and results have been inconsistent. We aimed to examine the association between MetS factors (individually and combined) and risk of breast cancer incidence and mortality. METHODS: Two hundred ninety thousand women from Austria, Norway, and Sweden were enrolled during 1974-2005, with measurements of height, weight, blood pressure, and levels of glucose, cholesterol, and triglycerides. Relative risks (RR) of breast cancer were estimated using Cox proportional hazards regression for each MetS factor in quintiles and for standardized levels (z-scores) and for a composite z-score for the MetS. RESULTS: There were 4,862 incident cases of breast cancer and 633 deaths from breast cancer identified. In women below age 50, there was a decreased risk of incident cancer for the MetS (per 1-unit increment of z-score; RR, 0.83; 95% confidence interval, 0.76-0.90) as well as for the individual factors (except for glucose). The lowest risks were seen among the heaviest women. In women above age 60, there was an increased risk of breast cancer mortality for the MetS (RR, 1.23; 95% confidence interval, 1.04-1.45) and for blood pressure and glucose. The strongest association with mortality was seen for increased glucose concentrations. CONCLUSIONS: The MetS was associated with a decreased risk of incident breast cancer in women below age 50 with high body mass index, and with an increased risk of breast cancer mortality in women above 60. IMPACT: Lifestyle interventions as recommended for cardiovascular disease prevention may be of value to prevent breast cancer mortality in postmenopausal women.

    Metabolic risk factors and ovarian cancer in the metabolic syndrome and cancer project2011Inngår i: International Journal of Epidemiology, ISSN 0300-5771, E-ISSN 1464-3685, Vol. 40, nr 6, s. 1667-1677Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: No studies have so far evaluated the impact of the metabolic syndrome (MetS) as an entity on ovarian cancer risk. The authors aimed to examine the association between factors in the MetS, individually and combined, and risk of ovarian cancer incidence and mortality. METHODS: Altogether, 290 000 women from Austria, Norway and Sweden were enrolled during 1974-2005, with measurements taken of height, weight, blood pressure and levels of glucose, cholesterol and triglycerides. Relative risks (RRs) of ovarian cancer were estimated using Cox regression for each MetS factor in quintiles and for standardized levels (z-scores), and for a composite z-score for the MetS. RRs were corrected for random error in measurements. RESULTS: During follow-up, 644 epithelial ovarian cancers and 388 deaths from ovarian cancer were identified. There was no overall association between MetS and ovarian cancer risk. Increasing levels of cholesterol [RR 1.52, 95% confidence interval (95% CI) 1.01-2.29, per 1-U increment of z-score] and blood pressure (RR 1.79, 95% CI 1.12-2.86) conferred, however, increased risks of mucinous and endometrioid tumours, respectively. In women below the age of 50 years, there was increased risk of ovarian cancer mortality for MetS (RR 1.52, 95% CI 1.00-2.30). Increasing levels of BMI (RR 1.17, 95% CI 1.01-1.37) conferred increased risk of ovarian cancer mortality in women above the age of 50 years. CONCLUSION: There was no overall association between MetS and ovarian cancer risk. However, increasing levels of cholesterol and blood pressure increased the risks of mucinous and endometrioid tumours, respectively. Increasing levels of BMI conferred an increased risk of ovarian cancer mortality in women above the age of 50 years.

    Metabolic syndrome and endometrial carcinoma2010Inngår i: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 171, nr 8, s. 892-902Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The authors examined the association between the metabolic syndrome and risk of incident endometrial and fatal uterine corpus cancer within a large prospective cohort study. Approximately 290,000 women from Austria, Norway, and Sweden were enrolled during 1974-2005, with measurements of height, weight, systolic and diastolic blood pressure, and circulating levels of glucose, total cholesterol, and triglycerides. Relative risks were estimated using Cox proportional hazards regression. The metabolic syndrome was assessed as a composite z score, as the standardized sum of z scores for body mass index, blood pressure, glucose, cholesterol, and triglycerides. A total of 917 endometrial carcinomas and 129 fatal cancers were identified. Increased risks of incident endometrial carcinoma and fatal uterine corpus cancer were seen for the metabolic syndrome factors combined, as well as for individual factors (except for cholesterol). The relative risk of endometrial carcinoma for the metabolic syndrome was 1.37 (95% confidence interval: 1.28, 1.46) per 1-unit increment of z score. The positive associations between metabolic syndrome factors (both individually and combined) and endometrial carcinoma were confined to the heaviest women. The association between the metabolic syndrome and endometrial carcinoma risk seems to go beyond the risk conferred by obesity alone, particularly in women with a high body mass index.

    Carboxylic ester hydrolase: a serum marker of acute pancreatitis1987Inngår i: Pancreas, ISSN 0885-3177, E-ISSN 1536-4828, Vol. 2, nr 5, s. 597-603Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    By use of an enzyme-linked immunosorbent assay we established serum reference values of carboxylic ester hydrolase, a pancreatic secretory lipolytic enzyme, and explored to see if a raised serum level is indicative of acute pancreatitis. Postoperative elevation of carboxylic ester hydrolase was observed in seven out of ten patients who underwent pancreatic surgery. Serum levels of carboxylic ester hydrolase and amylase were determined in 129 patients admitted due to abdominal emergency conditions. Amylase was elevated in 27 patients, and in 20 of these raised carboxylic ester hydrolase levels affirmed the diagnosis acute pancreatitis. In five out of the seven patients with elevated amylase alone no etiologic factor of acute pancreatitis was found. Another 11 patients had raised carboxylic ester hydrolase levels without concomitant elevation of amylase. In all these patients, a likely cause of pancreatic inflammation was identifiable. Hence, a raised carboxylic ester hydrolase level, even in presence of normal amylase, could be indicative of acute pancreatic inflammation.

    Physical Activity and Survival among Men Diagnosed with Prostate Cancer2015Inngår i: Cancer Epidemiology, Biomarkers and Prevention, ISSN 1055-9965, E-ISSN 1538-7755, Vol. 24, nr 1, s. 57-64Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Few studies have investigated the association between post-diagnosis physical activity and mortality among men diagnosed with prostate cancer. The aim of this study was to investigate the effect of physical activity after a prostate cancer diagnosis on both overall and prostate cancer-specific mortality in a large cohort. Methods: Data from 4,623 men diagnosed with localized prostate cancer 1997-2002 and followed-up until 2012 were analyzed. HRs with 95% confidence intervals (CI) were estimated using Cox proportional hazards models to examine the association between post-diagnosis recreational MET-h/d, time spent walking/bicycling, performing household work or exercising, and time to overall and prostate cancer-specific death. All models were adjusted for potential confounders. Results: During the follow-up, 561 deaths of any cause and 194 deaths from prostate cancer occurred. Statistically significantly lower overall mortality rates were found among men engaged in 5 recreationalMET-h/d (HR, 0.63; 95% CI, 0.52-0.77), walking/ bicycling 20 min/d (HR, 0.70; 95% CI, 0.57-0.86), performing householdwork > 1 h/d (HR, 0.71; 95% CI, 0.59-0.86), or exercising > 1 h/wk (HR, 0.74; 95% CI, 0.61-0.90), compared with less active men within each activity type. For prostate cancer-specific mortality, statistically significantly lower mortality rates were seen among men walking/bicycling >= 20 min/d (HR, 0.61; 95% CI, 0.43-0.87) or exercising 1 h/wk (HR, 0.68; 95% CI, 0.48-0.94). Conclusions: Higher levels of physical activity were associated with reduced rates of overall and prostate cancer-specific mortality. Impact: Our study further strengthens previous results indicating beneficial effects of physical activity on survival among men with prostate cancer. Cancer Epidemiol Biomarkers Prev; 24(1); 57-64.

    Body mass index and weight change in men with prostate cancer: progression and mortality2014Inngår i: Cancer Causes and Control, ISSN 0957-5243, E-ISSN 1573-7225, Vol. 25, nr 8, s. 933-943Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Body mass index (BMI) is a modifiable lifestyle factor that has been associated with an increased risk of fatal prostate cancer and biochemical recurrence. The main purpose of the present study was to investigate the association between the exposure BMI at the time of a prostate cancer diagnosis and weight change after diagnosis, and the outcomes of prostate cancer progression and mortality in a large cohort study. Data from 4,376 men diagnosed with clinically localized prostate cancer between 1997 and 2002 were analyzed. BMI and weight change were self-reported in 2007. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were estimated in complete-case analysis (n = 3,214) using Cox proportional hazards models. Progression was experienced among 639 (14.6 %) of the study participants, and in total, 450 (10.3 %) deaths of any cause and 134 (3.1 %) prostate cancer-specific deaths were recorded during follow-up. Obese men had a 47 % increased rate of overall mortality compared to normal weight men (HR 1.47, 95 % CI 1.03-2.10). No statistically significant associations were found for BMI and prostate cancer progression or prostate cancer-specific mortality. A weight loss > 5 % after diagnosis almost doubled the rate of overall mortality compared to maintaining a stable weight (HR 1.94, 95 % CI 1.41-2.66), while a weight gain > 5 % was associated with an almost doubled increased rate of prostate cancer-specific mortality (HR 1.93, 95 % CI 1.18-3.16). Being obese was associated with an increased rate of overall mortality, and gaining weight after a prostate cancer diagnosis was associated with an increased rate of prostate cancer-specific mortality.

    A prospective study on metabolic risk factors and gallbladder cancer in the metabolic syndrome and cancer (Me-Can) collaborative study2014Inngår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 9, nr 2, s. e89368-Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To investigate the association between metabolic risk factors (individually and in combination) and risk of gallbladder cancer (GBC). Methods: The metabolic syndrome and cancer project (Me-Can) includes cohorts from Norway, Austria, and Sweden with data on 578,700 men and women. We used Cox proportional hazard regression models to calculate relative risks of GBC by body mass index (BMI), blood pressure, and plasma levels of glucose, cholesterol, and triglycerides as continuous standardised variables and their standardised sum of metabolic syndrome (MetS) z-score. The risk estimates were corrected for random error in measurements. Results: During an average follow-up of 12.0 years (SD = 7.8), 184 primary gallbladder cancers were diagnosed. Relative risk of gallbladder cancer per unit increment of z-score adjusted for age, smoking status and BMI (except for BMI itself) and stratified by birth year, sex and sub-cohorts, was for BMI 1.31 (95% confidence interval 1.11, 1.57) and blood glucose 1.76 (1.10, 2.85). Further analysis showed that the effect of BMI on GBC risk is larger among women in the premenopausal age group (1.84 (1.23, 2.78)) compared to those in the postmenopausal age group (1.29 (0.93, 1.79)). For the other metabolic factors no significant association was found (mid blood pressure 0.96 (0.71, 1.31), cholesterol 0.84 (0.66, 1.06) and serum triglycerides 1.16 (0.82, 1.64)). The relative risk per one unit increment of the MetS z-score was 1.37 (1.07, 1.73). Conclusion: This study showed that increasing BMI and impaired glucose metabolism pose a possible risk for gallbladder cancer. Beyond the individual factors, the results also showed that the metabolic syndrome as an entity presents a risk constellation for the occurrence of gallbladder cancer.

    Long-term temporal trends in cardiovascular and metabolic risk factors2009Inngår i: Wiener Klinische Wochenschrift, ISSN 0043-5325, E-ISSN 1613-7671, Vol. 121, nr 19-20, s. 623-630Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: Metabolic factors such as obesity, hypertension, dyslipidemia and hyperglycemia have consistently been associated with increased risk of cardiovascular disease. There is also growing evidence that these factors are linked to cancer incidence and mortality. The aim of this study was to investigate long-term trends in major metabolic risk factors in three large cohorts. MATERIALS AND METHODS: Data from 239,602 individuals aged 25-64 years participating in health examinations between 1976 and 2005 were used to estimate prevalence and trends in five risk factors. RESULTS: Irrespective of geographic location, individual metabolic risk factors showed divergent trends across the observation period. Whereas obesity and hyperglycemia in men increased by a per decade ratio of 1.54 (95% CI: 1.42-1.66) and 1.62 (95% CI: 1.49-1.76), respectively, and in women by 1.48 (95% CI: 1.41-1.56) and 1.66 (95% CI: 1.57-1.75), hypertension decreased by 0.71 (95% CI: 0.68-0.74) in men and 0.83 (95% CI: 0.79-0.86) in women. Dyslipidemia increased from the 1970s to the 1980s but declined in the succeeding decade. A combination of three or more of these risk factors increased significantly in men by a ratio of 1.15 (95% CI: 1.08-1.22) per decade and in women by 1.20 (95% CI: 1.15-1.27). CONCLUSION: The study shows that individual metabolic risk factors followed divergent trends over the period of three decades even though the combination of three or more risk factors used as a proxy for the metabolic syndrome appeared to be stable over the last two of the decades. The two key components of the syndrome, namely BMI and glucose levels, increased significantly and deserve professional attention.

    Metabolic risk factors and primary liver cancer in a prospective study of 578,700 adults2012Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 131, nr 1, s. 193-200Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Initial studies have indicated diabetes and obesity to be risk factors for hepatocellular carcinoma; but the association between other metabolic risk factors and primary liver cancer (PLC) has not been investigated. The metabolic syndrome and cancer project (Me-Can) includes cohorts from Norway, Austria and Sweden with data on 578,700 subjects. We used Cox proportional hazard models to calculate relative risks (RRs) of PLC by body mass index (BMI), blood pressure and plasma levels of glucose, cholesterol and triglycerides as continuous standardized variables (z-score with mean = 0 and standard deviation (SD) = 1) and their standardized sum of metabolic syndrome (MetS) z-score. RRs were corrected for random error in measurements. During an average follow-up of 12.0 years (SD = 7.8), 266 PLCs were diagnosed among cohort members. RR of liver cancer per unit increment of z-score adjusted for age, smoking status and BMI and stratified by birth year, sex and sub-cohorts, was for BMI 1.39 (95% confidence interval (CI) 1.24-1.58), mid blood pressure 2.08 (0.95-4.73), blood glucose 2.13 (1.55-2.94) cholesterol 0.62 (0.51-0.76) and serum triglycerides 0.85 (0.65-1.10). The RR per one unit increment of the MetS z-score was 1.35 (1.12-1.61). BMI, glucose and a composite MetS score were positively and cholesterol negatively associated with risk of liver cancer.

    Prostate Cancer Radiation Therapy and Risk of Thromboembolic Events2017Inngår i: International Journal of Radiation Oncology, Biology, Physics, ISSN 0360-3016, E-ISSN 1879-355X, Vol. 97, nr 5, s. 1026-1031Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: To investigate the risk of thromboembolic disease (TED) after radiation therapy (RT) with curative intent for prostate cancer (PCa). Patients and Methods: We identified all men who received RT as curative treatment (n=9410) and grouped according to external beam RT (EBRT) or brachytherapy (BT). By comparing with an age-and county-matched comparison cohort of PCa-free men (n = 46,826), we investigated risk of TED after RT using Cox proportional hazard regression models. The model was adjusted for tumor characteristics, demographics, comorbidities, PCa treatments, and known risk factors of TED, such as recent surgery and disease progression. Results: Between 2006 and 2013, 6232 men with PCa received EBRT, and 3178 underwent BT. A statistically significant association was found between EBRT and BT and risk of pulmonary embolism in the crude analysis. However, upon adjusting for known TED risk factors these associations disappeared. No significant associations were found between BT or EBRT and deep venous thrombosis. Conclusion: Curative RT for prostate cancer using contemporary methodologies was not associated with an increased risk of TED.

    Alcohol consumption and risk of urothelial cell bladder cancer in the European prospective investigation into cancer and nutrition cohort2017Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 141, nr 10, s. 1963-1970Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Findings on the association between alcohol consumption and bladder cancer are inconsistent. We investigated that association in the European Prospective Investigation into Cancer and Nutrition cohort. We included 476,160 individuals mostly aged 35-70 years, enrolled in ten countries and followed for 13.9 years on average. Hazard ratios (HR) for developing urothelial cell carcinoma (UCC; 1,802 incident cases) were calculated using Cox proportional hazards models. Alcohol consumption at baseline and over the life course was analyzed, as well as different types of beverages (beer, wine, spirits). Baseline alcohol intake was associated with a statistically nonsignificant increased risk of UCC (HR 1.03; 95% confidence interval (CI) 1.00-1.06 for each additional 12 g/day). HR in smokers was 1.04 (95% CI 1.01-1.07). Men reporting high baseline intakes of alcohol (>96 g/day) had an increased risk of UCC (HR 1.57; 95% CI 1.03-2.40) compared to those reporting moderate intakes (<6 g/day), but no dose-response relationship emerged. In men, an increased risk of aggressive forms of UCC was observed even at lower doses (>6 to 24 g/day). Average lifelong alcohol intake was not associated with the risk of UCC, however intakes of spirits>24 g/day were associated with an increased risk of UCC in men (1.38; 95% CI 1.01-1.91) and smokers (1.39; 95% CI 1.01-1.92), compared to moderate intakes. We found no association between alcohol and UCC in women and never smokers. In conclusion, we observed some associations between alcohol and UCC in men and in smokers, possibly because of residual confounding by tobacco smoking.

    Subgroups of castration-resistant prostate cancer bone metastases defined through an inverse relationship between androgen receptor activity and immune response2017Inngår i: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 71, nr 5, s. 776-787Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Novel therapies for men with castration-resistant prostate cancer (CRPC) are needed, particularly for cancers not driven by androgen receptor (AR) activation. Objectives: To identify molecular subgroups of PC bone metastases of relevance for therapy.

    Design, setting, and participants: Fresh-frozen bone metastasis samples from men with CRPC (n = 40), treatment-naïve PC (n = 8), or other malignancies (n = 12) were characterized using whole-genome expression profiling, multivariate principal component analysis (PCA), and functional enrichment analysis. Expression profiles were verified by reverse transcription–polymerase chain reaction (RT-PCR) in an extended set of bone metastases (n = 77) and compared to levels in malignant and adjacent benign prostate tissue from patients with localized disease (n = 12). Selected proteins were evaluated using immunohistochemistry. A cohort of PC patients (n = 284) diagnosed at transurethral resection with long follow-up was used for prognostic evaluation.

    Results and limitations: The majority of CRPC bone metastases (80%) was defined as AR-driven based on PCA analysis and high expression of the AR, AR co-regulators (FOXA1, HOXB13), and AR-regulated genes (KLK2, KLK3, NKX3.1, STEAP2, TMPRSS2); 20% were non–AR-driven. Functional enrichment analysis indicated high metabolic activity and low immune responses in AR-driven metastases. Accordingly, infiltration of CD3+ and CD68+ cells was lower in AR-driven than in non–AR-driven metastases, and tumor cell HLA class I ABC immunoreactivity was inversely correlated with nuclear AR immunoreactivity. RT-PCR analysis showed low MHC class I expression (HLA-A, TAP1, and PSMB9 mRNA) in PC bone metastases compared to benign and malignant prostate tissue and bone metastases of other origins. In primary PC, low HLA class I ABC immunoreactivity was associated with high Gleason score, bone metastasis, and short cancer-specific survival. Limitations include the limited number of patients studied and the single metastasis sample studied per patient.

    Conclusions: Most CRPC bone metastases show high AR and metabolic activities and low immune responses. A subgroup instead shows low AR and metabolic activities, but high immune responses. Targeted therapy for these groups should be explored. Patient summary: We studied heterogeneities at a molecular level in bone metastasis samples obtained from men with castration-resistant prostate cancer. We found differences of possible importance for therapy selection in individual patients.

    Marked response to cabazitaxel in prostate cancer xenografts expressing androgen receptor variant 7 and reversion of acquired resistance by anti-androgens2019Inngår i: The Prostate, ISSN 0270-4137, E-ISSN 1097-0045Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Taxane treatment may be a suitable therapeutic option for patients with castration‐resistant prostate cancer and high expression of constitutively active androgen receptor variants (AR‐Vs). The aim of the study was to compare the effects of cabazitaxel and androgen deprivation treatments in a prostate tumor xenograft model expressing high levels of constitutively active AR‐V7. Furthermore, mechanisms behind acquired cabazitaxel resistance were explored.

    Methods: Mice were subcutaneously inoculated with 22Rv1 cells and treated with surgical castration (n = 7), abiraterone (n = 9), cabazitaxel (n = 6), castration plus abiraterone (n = 8), castration plus cabazitaxel (n = 11), or vehicle and/or sham operation (n = 23). Tumor growth was followed for about 2 months or to a volume of approximately 1000 mm3. Two cabazitaxel resistant cell lines; 22Rv1‐CabR1 and 22Rv1‐CabR2, were established from xenografts relapsing during cabazitaxel treatment. Differential gene expression between the cabazitaxel resistant and control 22Rv1 cells was examined by whole‐genome expression array analysis followed by immunoblotting, immunohistochemistry, and functional pathway analysis.

    Results: Abiraterone treatment alone or in combination with surgical castration had no major effect on 22Rv1 tumor growth, while cabazitaxel significantly delayed and in some cases totally abolished 22Rv1 tumor growth on its own and in combination with surgical castration. The cabazitaxel resistant cell lines; 22Rv1‐CabR1 and 22Rv1‐CabR2, both showed upregulation of the ATP‐binding cassette sub‐family B member 1 (ABCB1) efflux pump. Treatment with ABCB1 inhibitor elacridar completely restored susceptibility to cabazitaxel, while treatment with AR‐antagonists bicalutamide and enzalutamide partly restored susceptibility to cabazitaxel in both cell lines. The cholesterol biosynthesis pathway was induced in the 22Rv1‐CabR2 cell line, which was confirmed by reduced sensitivity to simvastatin treatment.

    Conclusions: Cabazitaxel efficiently inhibits prostate cancer growth despite the high expression of constitutively active AR‐V7. Acquired cabazitaxel resistance involving overexpression of efflux transporter ABCB1 can be reverted by bicalutamide or enzalutamide treatment, indicating the great clinical potential for combined treatment with cabazitaxel and anti‐androgens.

    Molecular Stratification of Clear Cell Renal Cell Carcinoma by Consensus Clustering Reveals Distinct Subtypes and Survival Patterns.2010Inngår i: Genes & cancer, ISSN 1947-6027, Vol. 1, nr 2, s. 152-163Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Clear cell renal cell carcinoma (ccRCC) is the predominant RCC subtype, but even within this classification, the natural history is heterogeneous and difficult to predict. A sophisticated understanding of the molecular features most discriminatory for the underlying tumor heterogeneity should be predicated on identifiable and biologically meaningful patterns of gene expression. Gene expression microarray data were analyzed using software that implements iterative unsupervised consensus clustering algorithms to identify the optimal molecular subclasses, without clinical or other classifying information. ConsensusCluster analysis identified two distinct subtypes of ccRCC within the training set, designated clear cell type A (ccA) and B (ccB). Based on the core tumors, or most well-defined arrays, in each subtype, logical analysis of data (LAD) defined a small, highly predictive gene set that could then be used to classify additional tumors individually. The subclasses were corroborated in a validation data set of 177 tumors and analyzed for clinical outcome. Based on individual tumor assignment, tumors designated ccA have markedly improved disease-specific survival compared to ccB (median survival of 8.6 vs 2.0 years, P = 0.002). Analyzed by both univariate and multivariate analysis, the classification schema was independently associated with survival. Using patterns of gene expression based on a defined gene set, ccRCC was classified into two robust subclasses based on inherent molecular features that ultimately correspond to marked differences in clinical outcome. This classification schema thus provides a molecular stratification applicable to individual tumors that has implications to influence treatment decisions, define biological mechanisms involved in ccRCC tumor progression, and direct future drug discovery.

    Prostate cancer diagnosed after prostate-specific antigen testing of men without clinical signs of the disease: a population-based study from the National Prostate Cancer Register of Sweden2010Inngår i: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 44, nr 6, s. 384-390Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. To investigate the effects of prostate-specific antigen (PSA) testing of men without clinical signs of prostate cancer on the incidence of prostate cancer in Sweden. Material and methods. Information on the cause of diagnosis, tumour characteristics and primary treatment for patients diagnosed with prostate cancer between January 1999 and December 2007 was extracted from the National Prostate Cancer Register of Sweden. This register includes data for 95% of Swedish prostate cancer cases. Results. The total age-standardized annual incidence of prostate cancer per 100 000 men increased from 187 in 1999 to 233 in 2004, but decreased thereafter to 196 in 2007. The incidence of asymptomatic cases also peaked in 2004 (at 62 per 100 000 men), but varied six-fold between different counties in that year (16–98 per 100 000 men). Asymptomatic cases (n = 17 143) constituted 15% of all new cases in 2000 and 30% in 2007. Almost as many cases were diagnosed in stage T1c in men with symptoms, usually from the lower urinary tract. Together these two groups constituted 29% of all new cases in 2000 and 52% in 2007. It was estimated that at least one-third of all Swedish men aged 50–75 years had a PSA test between 2000 and 2007. Conclusions. Even though screening for prostate cancer is not recommended in Sweden, PSA testing of men without clinical signs of prostate cancer is common. The effects on the Swedish incidence of prostate cancer were similar to those reported from the USA.

    The Study of Active Monitoring in Sweden (SAMS): A randomized study comparing two different follow-up schedules for active surveillance of low-risk prostate cancer2013Inngår i: Scandinavian Journal of Urology, ISSN 2168-1805, Vol. 47, nr 5, s. 347-355Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Objective. Only a minority of patients with low-risk prostate cancer needs treatment, but the methods for optimal selection of patients for treatment are not established. This article describes the Study of Active Monitoring in Sweden (SAMS), which aims to improve those methods. Material and methods. SAMS is a prospective, multicentre study of active surveillance for low-risk prostate cancer. It consists of a randomized part comparing standard rebiopsy and follow-up with an extensive initial rebiopsy coupled with less intensive follow-up and no further scheduled biopsies (SAMS-FU), as well as an observational part (SAMS-ObsQoL). Quality of life is assessed with questionnaires and compared with patients receiving primary curative treatment. SAMS-FU is planned to randomize 500 patients and SAMS-ObsQoL to include at least 500 patients during 5 years. The primary endpoint is conversion to active treatment. The secondary endpoints include symptoms, distant metastases and mortality. All patients will be followed for 10-15 years. Results. Inclusion started in October 2011. In March 2013, 148 patients were included at 13 Swedish urological centres. Conclusions. It is hoped that the results of SAMS will contribute to fewer patients with indolent, low-risk prostate cancer receiving unnecessary treatment and more patients on active surveillance who need treatment receiving it when the disease is still curable. The less intensive investigational follow-up in the SAMS-FU trial would reduce the healthcare resources allocated to this large group of patients if it replaced the present standard schedule.

    Family History and Probability of Prostate Cancer, Differentiated by Risk Category: A Nationwide Population-Based Study2016Inngår i: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 108, nr 10, artikkel-id djw110Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Familial prostate cancer risk estimates are inflated by clinically insignificant low-risk cancer, diagnosed after prostate-specific antigen testing. We provide age-specific probabilities of non-low-and high-risk prostate cancer. Methods: Fifty-one thousand, eight hundred ninety-seven brothers of 32 807 men with prostate cancer were identified in Prostate Cancer data Base Sweden (PCBaSe). Nelson-Aalen estimates with 95% confidence intervals (CIs) were calculated for cumulative, family history-stratified probabilities of any, non-low-(any of Gleason score >= 7, prostate-specific antigen [PSA] >= 10 ng/mL, T3-4, N1, and/or M1) and high-risk prostate cancer (Gleason score >= 8 and/or T3-4 and/or PSA >= 20 ng/mL and/or N1 and/or M1). Results: The population probability of any prostate cancer was 4.8% (95% CI = 4.8% to 4.9%) at age 65 years and 12.9% (95% CI = 12.8% to 12.9%) at age 75 years, of non-low-risk prostate cancer 2.8% (95% CI = 2.7% to 2.8%) at age 65 years and 8.9% (95% CI = 8.8% to 8.9%) at age 75 years, and of high-risk prostate cancer 1.4% (95% CI = 1.3% to 1.4%) at age 65 years and 5.2% (95% CI = 5.1% to 5.2%) at age 75 years. For men with one affected brother, probabilities of any prostate cancer were 14.9% (95% CI = 14.1% to 15.8%) at age 65 years and 30.3% (95% CI = 29.3% to 31.3%) at age 75 years, of non-low-risk prostate cancer 7.3% (95% CI = 6.7% to 7.9%) at age 65 years and 18.8% (95% CI = 17.9% to 19.6%) at age 75 years, and of high-risk prostate cancer 3.0% (95% CI = 2.6% to 3.4%) at age 65 years and 8.9% (95% CI = 8.2% to 9.5%) at age 75 years. Probabilities were higher for men with a stronger family history. For example, men with two affected brothers had a 13.6% (95% CI = 9.9% to 17.6 %) probability of high-risk cancer at age 75 years. Conclusions: The age-specific probabilities of non-low-and high-risk cancer presented here are more informative than relative risks of any prostate cancer and more suitable to use for counseling men with a family history of prostate cancer.

    Undertreatment of Men in Their Seventies with High-risk Nonmetastatic Prostate Cancer2015Inngår i: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 68, nr 1, s. 53-58Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Many elderly men with high-risk nonmetastatic prostate cancer (HRnMPCa) do not receive radical treatment, despite the high mortality associated with conservative management. Objective: To investigate how age and comorbidity affect treatment of men with HRnMPCa. Design, setting, and participants: This was an observational nationwide register study during 2001-2012. We identified 19 190 men of <80 yr of age diagnosed with HRnMPCa in the National Prostate Cancer Register of Sweden and 95 948 age-matched men without prostate cancer in the register of the total population. Outcome measurements and statistical analysis: The outcome was the proportion of men with HRnMPCa receiving radical treatment (radical prostatectomy or radiotherapy). Vital status and the Charlson comorbidity index (CCI) were obtained from nationwide registers. The 10-yr survival of men without prostate cancer, stratified by age and CCI, was used as a measure of the life expectancy of the men with prostate cancer. Results and limitations: The proportions receiving radical treatment varied with life expectancy among men younger than 70 yr, whereas use of these treatments did not match the long life expectancy of men in their seventies with CCI 0-1. Only 10% of men aged 75-80 yr with CCI 0 received radical treatment despite 52% probability of 10-yr life expectancy, compared with approximately half of the men younger than 70 yr with a similar life expectancy. The use of radical treatment for HRnMPCa increased with time in all Swedish counties, but a threefold difference between counties remained in 2009-2012 for patients aged 70-80 yr with CCI 0-1. Uncertain external validity is a study limitation, and the impact of physician versus patient preferences on treatment selection could not be assessed. Conclusions: Otherwise healthy men in their seventies with HRnMPCa were less likely to receive radical treatment than younger men with a similar life expectancy, although increasing use of radical treatment was observed during the study period. Our findings highlight the need for improved methods for clinical decision-making, including improved assessment of life expectancy. Patient summary: We performed a nationwide register study that showed that many healthy men in their seventies live for at least another 10 yr. Despite this long life expectancy, men in their seventies with high-risk nonmetastatic prostate cancer were often not treated with radical prostatectomy or radiotherapy, possibly because their life expectancy was underestimated. Our study highlights the need for improved clinical decision-making, which should incorporate an assessment of the patient's life expectancy.

    Effects of prostate-specific antigen testing on familial prostate cancer risk estimates2010Inngår i: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 102, nr 17, s. 1336-1343Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background Family history is a strong risk factor for prostate cancer. The aim of this study was to investigate whether increased diagnostic activity is related to the incidence of prostate cancer among brothers of men with prostate cancer.

    Methods Data were from the nationwide population-based Prostate Cancer Database Sweden (PCBaSe Sweden), which includes data from the National Prostate Cancer Register, the Swedish Cancer Register, the Register of the Total Population, the Multi-Generation Register, and the Census database. We investigated the relationship of tumor characteristics, time from diagnosis of the index patient (ie, prostate cancer patients in the National Prostate Cancer Register for whom at least one brother and their father could be identified), calendar period, geographic factors, and socioeconomic status to standardized incidence ratios (SIRs) for prostate cancer among 22 511 brothers of 13 975 index patients in PCBaSe Sweden.

    Results Brothers of index patients with prostate cancer were at increased risk for a diagnosis of prostate cancer (SIR = 3.1, 95% confidence interval [CI] = 2.9 to 3.3). Risk was higher for T1c tumors (SIR = 3.4, 95% CI = 3.2 to 3.8) than for metastatic tumors (SIR = 2.0, 95% CI = 1.5 to 2.6), and risk of T1c tumors was especially high during the first year after the diagnosis of the index patient (SIR = 4.3, 95% CI = 3.8 to 4.9), compared with the following years (SIR range = 2.8–3.3), and for brothers of index patients who had a higher socioeconomic status (SIR = 4.2, 95% CI = 3.7 to 4.7), compared with brothers of index patients with lower socioeconomic status (SIR = 2.8, 95% CI = 2.4 to 3.2).

    Conclusions Increased diagnostic activity among men with a family history of prostate cancer appears to contribute to their increased risk of prostate cancer and to lead to detection bias in epidemiological and genetic studies of familial prostate cancer.

    Macrophage inhibitory cytokine 1: a new prognostic marker in prostate cancer.2009Inngår i: Clinical Cancer Research, ISSN 1078-0432, E-ISSN 1557-3265, Vol. 15, nr 21, s. 6658-6664Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    PURPOSE: High serum levels of macrophage inhibitory cytokine 1 (MIC-1) are strongly associated with metastatic prostate cancer, suggesting MIC-1 is a biomarker for prostate cancer prognosis. EXPERIMENTAL DESIGN: We conducted a prospective cohort study of 1,442 Swedish men with a pathologically verified diagnosis of prostate cancer between 2001 and 2003. Blood was drawn either pretreatment (n = 431) or posttreatment (n = 1,011) and cases were followed for a mean time of 4.9 years (range, 0.1-6.8 years). RESULTS: MIC-1 serum levels independently predicted poor cancer-specific survival with an almost 3-fold higher cancer death rate in patients with serum levels in the highest quartile compared with men with serum levels in the lowest quartile (adjusted hazard ratio, 2.98; 95% confidence interval, 1.82-4.68). Pretreatment MIC-1 levels revealed an even stronger association with disease outcome with an 8-fold higher death rate in the highest compared with the lowest category (adjusted hazard ratio, 7.98; 95% confidence interval, 1.73-36.86). Among patients considered to have localized disease, MIC-1 significantly increased the discriminative capacity between indolent and lethal prostate cancer compared with the established prognostic markers clinical stage, pathologic grade, and prostate-specific antigen level (P = 0.016). A sequence variant in the MIC-1 gene was associated with decreased MIC-1 serum levels (P = 0.002) and decreased prostate cancer mortality (P = 0.003), suggesting a causative role of MIC-1 in prostate cancer prognosis. CONCLUSIONS: Serum MIC-1 concentration is a novel biomarker capable of predicting prostate cancer prognosis.

    The impact of the extent of lymphadenectomy on oncologic outcomes in patients undergoing radical cystectomy for bladder cancer: a systematic review2014Inngår i: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 66, nr 6, s. 1065-1077Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    CONTEXT: Controversy exists regarding the therapeutic value of lymphadenectomy (LND) in patients undergoing radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC). OBJECTIVE: To systematically review the relevant literature assessing the impact of LND on oncologic and perioperative outcomes in patients undergoing RC for MIBC. EVIDENCE ACQUISITION: Medline, Medline In-Process, Embase, the Cochrane Central Register of Controlled Trials, and the Latin American and Caribbean Center on Health Sciences Information (LILACS) were searched up to December 2013. Comparative studies reporting on no LND, limited LND (L-LND), standard LND (S-LND), extended LND (E-LND), superextended LND (SE-LND), and oncologic and perioperative outcomes were included. Risk-of-bias and confounding assessments were performed. EVIDENCE SYNTHESIS: Twenty-three studies reporting on 19 793 patients were included. All but one study were retrospective. Planned meta-analyses were not possible because of study heterogeneity; therefore, data were synthesized narratively. There were high risks of bias and confounding across most studies as well as extreme heterogeneity in the definition of the anatomic boundaries of LND templates. All seven studies comparing LND with no LND favored LND in terms of better oncologic outcomes. Seven of 14 studies comparing (super)extended LND with L-LND or S-LND reported a beneficial outcome for (super)extended LND in at least a subset of patients. No difference in outcome was reported in two studies comparing E-LND and S-LND. The comparative harms of different extents of LND remain unclear. CONCLUSIONS: Although the quality of the data was poor, the available evidence indicates that any kind of LND is advantageous over no LND. Similarly, E-LND appears to be superior to lesser degrees of dissection, while SE-LND offered no additional benefits. It is hoped that data from ongoing randomized clinical trials will clarify remaining uncertainties. PATIENT SUMMARY: The current literature suggests that removal of lymph nodes in bladder cancer surgery is beneficial and might result in better outcomes in terms of prolonging survival; however, the quality of the available studies is poor, and high-quality studies are needed.

    Adherence to the Mediterranean diet and risk of bladder cancer in the EPIC cohort study2014Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 134, nr 10, s. 2504-2511Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There is growing evidence of the protective role of the Mediterranean diet (MD) on cancer. However, to date no epidemiological study has investigated the influence of the MD on bladder cancer. We evaluated the association between adherence to the MD and risk of urothelial cell bladder cancer (UCC), according to tumor aggressiveness, in the European Prospective Investigation into Cancer and Nutrition (EPIC). The analysis included 477,312 participants, recruited from ten European countries between 1991 and 2000. Information from validated dietary questionnaires was used to develop a relative Mediterranean diet score (rMED), including nine dietary components. Cox regression models were used to assess the effect of the rMED on UCC risk, while adjusting for dietary energy and tobacco smoking of any kind. Stratified analyses were performed by sex, BMI, smoking status, European region and age at diagnosis. During an average follow-up of 11 years, 1,425 participants (70.9% male) were diagnosed with a first primary UCC. There was a negative but non-significant association between a high versus low rMED score and risk of UCC overall (HR: 0.84 [95% CI 0.69, 1.03]) and risk of aggressive (HR: 0.88 [95% CI 0.61, 1.28]) and non-aggressive tumors (HR: 0.78 [95% CI 0.54, 1.14]). Although there was no effect modification in the stratified analyses, there was a significant 34% (p = 0.043) decreased risk of UCC in current smokers with a high rMED score. In EPIC, the MD was not significantly associated with risk of UCC, although we cannot exclude that a MD may reduce risk in current smokers.

    Anticancer effects of a plant lignan 7-hydroxymatairesinol on a prostate cancer model in vivo.2005Inngår i: Experimental biology and medicine (Maywood, N.J.: Print), ISSN 1535-3702, E-ISSN 1535-3699, Vol. 230, nr 3, s. 217-223Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Clinical intervention studies and experimental studies with lignan-rich diets suggest that lignans may have inhibitory effects on prostate cancer, but no clinical or experimental studies with purified lignans have been published. The purpose of this study was to investigate the effect of a plant lignan 7-hydroxymatairesinol (HMR) on LNCaP human prostate cancer xenografts in athymic mice. Athymic nude male mice were injected subcutaneously with LNCaP cells. Starting 3 days after tumor cell injections, a control diet or a control diet supplemented with 0.15% or 0.30% of HMR was administered to mice and the tumor take rate and growth was observed for 9 weeks. HMR diet inhibited the growth of LNCaP tumors. Mice treated with HMR had smaller tumor volume, lower tumor take rate, increased proportion of nongrowing tumors, and higher tumor cell apoptotic index compared with controls. Furthermore, the cell proliferation index was reduced in mice receiving the 0.30% HMR diet compared with mice receiving the control diet. Our results suggest that dietary HMR started at the early phase of the tumor development inhibits the growth of the LNCaP human prostate cancer xenografts in athymic male mice.

    Consumption of vegetables and fruit and the risk of bladder cancer in the European Prospective Investigation into Cancer and Nutrition2009Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 125, nr 11, s. 2643-2651Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Previous epidemiologic studies found inconsistent associations between vegetables and fruit consumption and the risk of bladder cancer. We therefore investigated the association between vegetable and fruit consumption and the risk of bladder cancer among participants of the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Data on food consumption and complete follow-up for cancer occurrence was available for a total of 478,533 participants, who were recruited in 10 European countries. Estimates of rate ratios were obtained by Cox proportional hazard models, stratified by age at recruitment, gender and study centre, and adjusted for total energy intake, smoking status, duration of smoking and lifetime intensity of smoking. A calibration study in a subsample was used to control for dietary measurement errors. After a mean follow-up of 8.7 years, 1015 participants were newly diagnosed with bladder cancer. Increments of 100 g/day in fruit and vegetable consumption combined did not affect bladder cancer risk (i.e., calibrated HR = 0.98; 95%CI: 0.95-1.01). Borderline statistically significant lower bladder cancer risks were found among never smokers with increased consumption of fruit and vegetables combined (HR = 0.94 95%CI: 0.87-1.00 with increments of 100 g/day; calibrated HR = 0.92 95%CI 0.79-1.06) and increased consumption of apples and pears (hard fruit; calibrated HR = 0.90 95%CI: 0.82-0.98 with increments of 25 g/day). For none of the associations a statistically significant interaction with smoking status was found. Our findings do not support an effect of fruit and vegetable consumption, combined or separately, on bladder cancer risk. (c) 2009 UICC.

    Variety in vegetable and fruit consumption and risk of bladder cancer in the European prospective investigation into cancer and nutrition2011Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 128, nr 12, s. 2971-2979Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Recent research does not show an association between fruit and vegetable consumption and bladder cancer risk. None of these studies investigated variety in fruit and vegetable consumption, which may capture different aspects of consumption. We investigated whether a varied consumption of vegetables and fruits is associated with bladder cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) study. Detailed data on food consumption and complete follow-up for cancer incidence were available for 452,185 participants, who were recruited from ten European countries. After a mean follow-up of 8.7 years, 874 participants were diagnosed with bladder cancer. Diet diversity scores (DDSs) were used to quantify the variety in fruit and vegetable consumption. Multivariable Cox proportional hazard models were used to assess the effect of the DDSs on bladder cancer risk. There was no evidence of a statistically significant association between bladder cancer risk and any of the DDSs when these scores were considered as continuous covariates. However, the hazard ratio (HR) for the highest tertile of the DDS for combined fruit and vegetable consumption was marginally significant compared to the lowest (HR = 1.30, 95% confidence interval: 1.00-1.69, p-trend = 0.05). In EPIC, there is no clear association between a varied fruit and vegetable consumption and bladder cancer risk. This finding provides further evidence for the absence of any strong association between fruit and vegetable consumption as measured by a food frequency questionnaire and bladder cancer risk.

    Genetic variability of the fatty acid synthase pathway is not associated with prostate cancer risk in the European Prospective Investigation on Cancer (EPIC)2011Inngår i: European Journal of Cancer, ISSN 0959-8049, E-ISSN 1879-0852, Vol. 47, nr 3, s. 420-427Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A western lifestyle, characterised by low rates of energy expenditure and a high-energy diet rich in animal protein, saturated fats and refined carbohydrates, is associated with high incidence of prostate cancer in men. A high-energy nutritional status results in insulin/IGF signalling in cells, which in turn stimulates synthesis of fatty acids. We investigated whether the genetic variability of the genes belonging to the fatty acid synthesis pathway is related to prostate cancer risk in 815 prostate cancer cases and 1266 controls from the European Prospective Investigation on Cancer (EPIC). Using a tagging approach and selecting 252 SNPs in 22 genes, we covered all the common genetic variation of this pathway. None of the SNPs reached statistical significance after adjusting for multiple comparisons. Common SNPs in the fatty acid synthase pathway are not major contributors to prostate cancer risk.

    Interactions Between Genetic Variants and Breast Cancer Risk Factors in the Breast and Prostate Cancer Cohort Consortium2011Inngår i: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 103, nr 16, s. 1252-1263Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background Recently, several genome-wide association studies have identified various genetic susceptibility loci for breast cancer. Relatively little is known about the possible interactions between these loci and the established risk factors for breast cancer. Methods To assess interactions between single-nucleotide polymorphisms (SNPs) and established risk factors, we prospectively collected DNA samples and questionnaire data from 8576 breast cancer case subjects and 11 892 control subjects nested within the National Cancer Institute's Breast and Prostate Cancer Cohort Consortium (BPC3). We genotyped 17 germline SNPs (FGFR2-rs2981582, FGFR2-rs3750817, TNRC9-rs3803662, 2q35-rs13387042, MAP3K1-rs889312, 8q24-rs13281615, CASP8-rs1045485, LSP1-rs3817198, COL1A1-rs2075555, COX11-rs6504950, RNF146-rs2180341, 6q25-rs2046210, SLC4A7-rs4973768, NOTCH2-rs11249433, 5p12-rs4415084, 5p12-rs10941679, RAD51L1-rs999737), and odds ratios were estimated by logistic regression to confirm previously reported associations with breast cancer risk. We performed likelihood ratio test to assess interactions between 17 SNPs and nine established risk factors (age at menarche, parity, age at menopause, use of hormone replacement therapy, family history, height, body mass index, smoking status, and alcohol consumption), and a correction for multiple testing of 153 tests (adjusted P value threshold = .05/153 = 3 x 10(-4)) was done. Casecase comparisons were performed for possible differential associations of polymorphisms by subgroups of tumor stage, estrogen and progesterone receptor status, and age at diagnosis. All statistical tests were two-sided. Results We confirmed the association of 14 SNPs with breast cancer risk (P(trend) = 2.57 x 10(-3) -3.96 x 10(-19)). Three SNPs (LSP1-rs3817198, COL1A1-rs2075555, and RNF146-rs2180341) did not show association with breast cancer risk. After accounting for multiple testing, no statistically significant interactions were detected between the 17 SNPs and the nine risk factors. We also confirmed that SNPs in FGFR2 and TNRC9 were associated with greater risk of estrogen receptor-positive than estrogen receptor-negative breast cancer (P(heterogeneity) = .0016 for FGFR2-rs2981582 and P(heterogeneity) = .0053 for TNRC9-rs3803662). SNP 5p12-rs10941679 was statistically significantly associated with greater risk of progesterone receptor-positive than progesterone receptor-negative breast cancer (P(heterogeneity) = .0028). Conclusion This study does not support the hypothesis that known common breast cancer susceptibility loci strongly modify the associations between established risk factors and breast cancer.

    CVD TiC/alumina multilayer coatings grown on sapphire single crystals2011Inngår i: Micron, ISSN 0968-4328, E-ISSN 1878-4291, Vol. 42, nr 8, s. 808-818Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Multilayers of TiC/α-Al(2)O(3) consisting of three (1μm thick) alumina layers separated by thin (∼10nm) oxidized TiC layers have been deposited onto c-, a- and r-surfaces of single crystals of α-Al(2)O(3) by chemical vapour deposition (CVD). The aim of this paper is to describe and compare the detailed microstructure of the different multilayer coatings by using transmission electron microscopy (TEM). The general microstructure of the alumina layers is very different when deposited onto different surfaces of α-Al(2)O(3) single crystal substrates. On the c- and a-surfaces the alumina layers grow evenly resulting in growth of single crystal layers of TiC and alumina throughout the coating. However, when deposited on the r-surface the alumina layers generally grow unevenly. No pores are observed within the alumina layers, while a small number of pores are found at the interfaces below the TiC layers. The TiC and alumina layers grow epitaxially on the c- and a-surface substrates. On the r-surface, epitaxy is present only at some rare locations. The TiC layers were oxidized in situ for 2min in CO(2)/H(2) prior to the alumina layer deposition. For all three samples chemical analyses show that the whole TiC layer is oxidized. On the c- and a-surfaces the TiC layer was oxidized to an fcc TiCO phase. On the r-surface the oxidation stage resulted in a transformation of the initially deposited fcc TiC to a monoclinic TiCO phase, which appears to be a modified TiO structure with a high carbon content.

    Nationwide population-based study on 30-day mortality after radical prostatectomy in Sweden.2009Inngår i: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 43, nr 5, s. 350-356Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: The incidence of prostate cancer in Sweden is increasing rapidly, as is treatment with curative intent. Radical prostatectomy (RP) is currently commonly performed, either within or outside large high-volume centres. The aim of this study was to assess the 30-day mortality rate after RP in Sweden. MATERIAL AND METHODS: In this nationwide population-based study, all men diagnosed with localized prostate cancer (< or =70 years, clinical stadium T1-2, prostate-specific antigen < 20 ng/ml) who underwent RP in Sweden between 1997 and 2002 were identified through the National Prostate Cancer Register (NPCR). Mortality within 30 days of RP was analysed through linkage between the follow-up study of the NPCR and the Regional Population Registers. The cause of death in the death certificates were compared with data from the hospitals concerned. To validate the results, a record linkage between the Inpatient Register and the National Population Register was also performed. RESULTS: The number of RPs performed increased over time. Among 3700 RPs performed, four deaths occurred during the first 30 days, yielding a 0.11% 30-day mortality rate. These deaths occurred at three different types of hospital and were all probably related to the RP. CONCLUSION: This study provides further evidence that RP is a procedure with very low perioperative mortality even when performed outside high-volume centres.

    Risk of suicide in men with low-risk prostate cancer2013Inngår i: European Journal of Cancer, ISSN 0959-8049, E-ISSN 1879-0852, Vol. 49, nr 7, s. 1588-1599Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Purpose: Risk of suicide is increased among men with prostate cancer. We investigated this association among men with low-risk cancer, usually detected by prostate specific antigen (PSA)-testing. Patients and Methods: Relative risk (RR) of suicide was calculated by use of Poisson regression analysis within the Prostate Cancer data Base Sweden (PCBaSe) 2.0, a nation-wide, population-based database, comparing 105,736 men diagnosed with prostate cancer between 1997-2009 to 528,658 matched prostate cancer-free men. Results: During the first 6 months after diagnosis, there were 38 suicides among men with prostate cancer; incidence rate 0.73 per 1000 person-years (PY) and 30 suicides in the comparison cohort; 0.11 per 1000 PY, corresponding to a RR of suicide of 6.5 (95% confidence interval (CI) 4.0-10). Risk was highest among men with distant metastases, incidence rate 1.25 per 1000 PY, RR 10 (95% CI 5.1-21) but risk was also increased for men with low-risk tumours, incidence rate difference 0.45 per 1000 PY and RR 5.2 (95% CI 2.3-12) and across categories of socioeconomic status and comorbidity. Eighteen months after diagnosis, risk of suicide had decreased to 0.27 per 1000 PY, RR 1.0 (95% CI 0.68-1.5) for low-risk prostate cancer but remained increased among men with metastases, 0.57 per 1000 PY, RR 1.8 (95% CI 1.1-2.9). Conclusion: Although the increase in absolute risk of suicide was modest, our findings reflect the severe psychological stress that prostate cancer patients may experience after diagnosis. The increased risk of suicide observed in men with prostate cancer, including low-risk, calls for increased awareness.

    Current routines for transrectal ultrasound-guided prostate biopsy: A web-based survey by the Swedish Urology Network2012Inngår i: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 46, nr 6, s. 405-410Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective. This study aimed to survey current Swedish practices for performing and handling transrectal ultrasound-guided prostate biopsies. Material and methods. A Swedish Urology Network (SUNe) was organized for the distribution of information, survey studies and research collaborations. A web-based questionnaire was distributed to the members in 2011. Results. In this first SUNe survey, 137 (91%) of the 151 members replied. All used antibiotic prophylaxis (84% ciprofloxacin, 12% trimethoprim-sulfamethoxazole), most commonly (63%) as a single dose of ciprofloxacin. Local anaesthesia was used by 87%. Half of the respondents only used a "side-fire" probe, whereas 17% always used an "end-fire" probe. Most (84%) routinely took 10 or more biopsy cores. About three-quarters started with the right base of the prostate and did not routinely take midline biopsies. More than one-third never or rarely sampled the anterior part of the prostate. There was great variability in how biopsy location was reported, but 71% considered a national standardized coordinate system desirable. Fine-needle aspiration was used occasionally by 39%, in more than 10% of cases by 6% and always by 2%. Most urologists mounted the biopsy cores on paper before fixation (78%), put only one core per jar (75%) and used flat-bottomed jars (70%). Conclusions. Most routines for handling of prostate biopsies, antibiotic prophylaxis, local anaesthesia and number of cores were uniform. However, there is still a need for standardization of the performance of ultrasound-guided biopsies. Although the method used to specify biopsy location varied greatly, most urologists would prefer a national standardized system.

    CpG dinucleotide-specific hypermethylation of the TNS3 gene promoter in human renal cell carcinoma2013Inngår i: Epigenetics, ISSN 1559-2294, E-ISSN 1559-2308, Vol. 8, nr 7, s. 739-747Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Tensin3 is a cytoskeletal regulatory protein that inhibits cell motility. Downregulation of the gene encoding Tensin3 (TNS3) in human renal cell carcinoma (RCC) may contribute to cancer cell metastatic behavior. We speculated that epigenetic mechanisms, e.g., gene promoter hypermethylation, might account for TNS3 downregulation. In this study, we identified and validated a TNS3 gene promoter containing a CpG island, and quantified the methylation level within this region in RCC. Using a luciferase reporter assay we demonstrated a functional minimal promoter activity for a 500-bp sequence within the TNS3 CpG island. Pyrosequencing enabled quantitative determination of DNA methylation of each CpG dinucleotide (a total of 43) in the TNS3 gene promoter. Across the entire analyzed CpG stretch, RCC DNA showed a higher methylation level than both non-tumor kidney DNA and normal control DNA. Out of all the CpGs analyzed, two CpG dinucleotides, specifically position 2 and 8, showed the most pronounced increases in methylation levels in tumor samples. Furthermore, CpG-specific higher methylation levels were correlated with lower TNS3 gene expression levels in RCC samples. In addition, pharmacological demethylation treatment of cultured kidney cells caused a 3-fold upregulation of Tensin3 expression. In conclusion, these results reveal a differential methylation pattern in the TNS3 promoter occurring in human RCC, suggesting an epigenetic mechanism for aberrant Tensin downregulation in human kidney cancer.

    Mini Review on the Use of Clinical Cancer Registers for Prostate Cancer: The National Prostate Cancer Register (NPCR) of Sweden2019Inngår i: FRONTIERS IN MEDICINE, ISSN 2296-858X, Vol. 6, artikkel-id 51Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Given the increasing prevalence of cancer, it is vital to systematically collect data in order to monitor disease trends and quality of cancer care. For this purpose, clinical cancer registries have been developed in some countries. These registers are intended to be used as a basis for quality assurance and quality improvement, but they also constitute a rich resource of real world data for research. The aim of thismini-review was to describe the structure and the organization of the National Prostate Cancer Register (NPCR) with some examples on how data in NPCR have affected prostate cancer care in Sweden.

    A high cannabinoid CB(1) receptor immunoreactivity is associated with disease severity and outcome in prostate cancer2009Inngår i: European Journal of Cancer, ISSN 0959-8049, E-ISSN 1879-0852, Vol. 45, nr 1, s. 174-182Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In the light of findings indicating that cannabinoids can affect the proliferation of a number of cancer cell types and that cannabinoid receptor expression is higher in prostate cancer cell lines than in non-malignant cells, we investigated whether the level of cannabinoid 1 receptor immunoreactivity (CB(1)IR) in prostate cancer tissues is associated with disease severity and outcome. Formalin-fixed paraffin-embedded non-malignant and tumour tissue samples from patients who were diagnosed with prostate cancer at a transurethral resection for voiding problems were used. CB(1)IR, which was scored in a total of 399 cases, was associated with the epithelial cell membranes, with little staining in the stroma. Patients with a tumour CB(1)IR score greater or equal to the median (2) had a significantly higher proportion of Gleason scores 8-10, metastases at diagnosis, tumour size and rate of cell proliferation at diagnosis than patients with a score<2. For 269 cases, tumour CB(1)IR was measured for patients who only received palliative therapy at the end stages of the disease, allowing the influence of CB(1)IR upon the disease outcome to be determined. Receiver operating characteristic (ROC) curves showed an area under the curve of 0.67 (95% confidence limits 0.59-0.74) for CB(1)IR in the tumour. CB(1)IR in non-malignant tissue was not associated with disease outcome. A tumour CB(1)IR score >or=2 was associated with a significantly lower disease specific survival. A Cox proportional hazards regression indicated that the tumour CB(1)IR score and the Gleason score were independent prognostic variables. It is concluded that a high tumour CB(1)IR score is associated with prostate cancer severity and outcome.

    Association between duration and type of androgen deprivation therapy and risk of diabetes in men with prostate cancer2016Inngår i: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 139, nr 12, s. 2698-2704Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Androgen deprivation therapy (ADT) for prostate cancer (PCa) increases risk of type 2 diabetes (T2DM); however the association between types and duration of ADT has not been fully elucidated. We examined how type and duration of ADT affects risk of T2DM. Using data from Prostate Cancer database Sweden (PCBaSe) we investigated risk of T2DM in a cohort of 34,031 men with PCa on ADT; i.e., anti-androgens (AA), orchiectomy, or gonadotropin-releasing hormone (GnRH) agonists compared to an age-matched, PCa-free comparison cohort (n = 167,205) using multivariate Cox proportional hazard regression. T2DM was defined as a newly filled prescription for metformin, sulphonylurea, or insulin in the Prescribed Drug Register. A total of 21,874 men with PCa received GnRH agonists, 9,143 AA and 3,014 underwent orchiectomy. Risk of T2DM was increased in men in the GnRH agonists/orchiectomy group during the first 3 years of ADT [i.e., 1 - 1.5 years HR: 1.61 (95%CI: 1.36 - 1.91)], compared to PCa-free men. The risk decreased thereafter (e.g., 3 - 4 years HR: 1.17 (95% CI: 0.98 - 1.40)). Conversely, no increased risk was seen in men on AA (HR: 0.74 (95%CI: 0.65 - 0.84). The incidence of T2DM per 1,000 person-years was 10 for PCa-free men, 8 for men on AA, and 13 for men on GnRH agonists/orchiectomy. Duration of ADT has a significant impact on risk of T2DM. With the peak after three years of treatment, our data indicates that men on ADT, even for a limited period of time, such as adjuvant to radiotherapy, are at increased risk of T2DM.

    Association between type 2 diabetes, curative treatment and survival in men with intermediate- and high-risk localized prostate cancer2018Inngår i: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 121, nr 2, s. 209-216Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To investigate whether curative prostate cancer (PCa) treatment was received less often by men with both PCa and Type 2 diabetes mellitus (T2DM) as little is known about the influence of T2DM diagnosis on the receipt of such treatment in men with localized PCa.

    Subjects and Methods: The Prostate Cancer database Sweden (PCBaSe) was used to obtain data on men with T2DM and PCa (n = 2210) for comparison with data on men with PCa only (n = 23 071). All men had intermediate-(T1-2, Gleason score 7 and/or prostate-specific antigen [PSA] 10-20 ng/mL) or high-risk (T3 and/or Gleason score 8-10 and/or PSA 20-50 ng/mL) localized PCa diagnosed between 1 January 2006 and 31 December 2014. Multivariate logistic regression was used to calculate the odds ratios (ORs) for receipt of curative treatment in men with and without T2DM. Overall survival, for up to 8 years of follow-up, was calculated both for men with T2DM only and for men with T2DM and PCa.

    Results: Men with T2DM were less likely to receive curative treatment for PCa than men without T2DM (OR 0.78, 95% confidence interval 0.69-0.87). The 8-year overall survival rates were 79% and 33% for men with T2DM and high-risk PCa who did and did not receive curative treatment, respectively.

    Conclusions: Men with T2DM were less likely to receive curative treatment for localized intermediate-and high-risk PCa. Men with T2DM and high-risk PCa who received curative treatment had substantially higher survival times than those who did not. Some of the survival differences represent a selection bias, whereby the healthiest patients received curative treatment. Clinicians should interpret this data carefully and ensure that individual patients with T2DM and PCa are not under-nor overtreated.

    Circulating Fatty Acids and Prostate Cancer Risk: Individual Participant Meta-Analysis of Prospective Studies2014Inngår i: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 106, nr 9, s. dju240-Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Background

    Individual studies have suggested that some circulating fatty acids are associated with prostate cancer risk, but have not been large enough to provide precise estimates of associations, particularly by stage and grade of disease.

    Methods

    Principal investigators of prospective studies on circulating fatty acids and prostate cancer were invited to collaborate. Investigators provided individual participant data on circulating fatty acids (weight percent) and other characteristics of prostate cancer cases and controls. Prostate cancer risk by study-specific fifths of 14 fatty acids was estimated using multivariable-adjusted conditional logistic regression. All statistical tests were two-sided.

    Results

    Five thousand and ninety-eight case patients and 6649 control patients from seven studies with an average follow-up of 5.1 (SD = 3.3) years were included. Stearic acid (18: 0) was inversely associated with total prostate cancer (odds ratio [OR] Q5 vs Q1 = 0.88, 95% confidence interval [CI] = 0.78 to 1.00, P-trend = .043). Prostate cancer risk was, respectively, 14% and 16% greater in the highest fifth of eicosapentaenoic acid (20:5n-3) (OR = 1.14, 95% CI = 1.01 to 1.29, P-trend = .001) and docosapentaenoic acid (22: 5n-3) (OR = 1.16, 95% CI = 1.02 to 1.33, P-trend = .003), but in each case there was heterogeneity between studies (P = .022 and P < .001, respectively). There was heterogeneity in the association between docosapentaenoic acid and prostate cancer by grade of disease (P = .006); the association was statistically significant for low-grade disease but not high-grade disease. The remaining 11 fatty acids were not statistically associated with total prostate cancer risk.

    Conclusion

    There was no strong evidence that circulating fatty acids are important predictors of prostate cancer risk. It is not clear whether the modest associations of stearic, eicosapentaenoic, and docosapentaenoic acid are causal.

    The influence of overweight and insulin resistance on breast cancer risk and tumour stage at diagnosis: a prospective study.2009Inngår i: Breast Cancer Research and Treatment, ISSN 0167-6806, E-ISSN 1573-7217, Vol. 113, nr 3, s. 567-576Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It is hypothesized that insulin resistance and related metabolic factors may influence breast cancer risk, however the epidemiological evidence remains inconclusive. We conducted a case–control study nested in a prospective cohort in Northern Sweden, to clarify the associations of body mass index (BMI), leptin, adiponectin, C-peptide, and glycated haemoglobin (HbA1c) with breast cancer risk. We also investigated whether these associations may be modified by age at diagnosis, tumour stage, and oestrogen and progesterone receptor status. During follow-up, 561 women developed invasive breast cancer and 561 matched controls were selected. Conditional logistic regression was used to calculate odds ratios (OR) as estimates of relative risk, and 95% confidence intervals (CI). The associations of BMI, leptin and HbA1c with breast cancer risk differed significantly according to whether the tumour was diagnosed as stage I or stage II–IV (P heterogeneity all <0.05). These factors were significantly inversely associated with risk in the group of stage I tumours, with ORs for top vs. bottom tertile for BMI of 0.48 (95% CI, 0.30–0.78, P trend = 0.004); leptin, 0.64 (95% CI, 0.41–1.00, P trend = 0.06); and HbA1c, 0.47 (95% CI, 0.28–0.80, P trend = 0.005). For stage II–IV tumours, there was a suggestion of an increased risk with higher levels of these factors. There were no significant differences in the associations of BMI, leptin, adiponectin, C-peptide and HbA1c with breast cancer risk in subgroups of age at diagnosis or tumour receptor status. This prospective study suggests that BMI, leptin and HbA1c influence breast tumour initiation and progression.

    Intensive Imaging-based Follow-up of Surgically Treated Localised Renal Cell Carcinoma Does Not Improve Post-recurrence Survival: Results from a European Multicentre Database (RECUR)2019Inngår i: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 75, nr 2, s. 261-264Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The optimal follow-up (FU) strategy for patients treated for localised renal cell carcinoma(RCC) remains unclear. Using the RECUR database, we studied imaging intensity utilised in contemporary FU to evaluate its association with outcome after detection of disease recurrence. Consecutive patients with nonmetastatic RCC (n = 1612) treated with curative intent at 12 institutes across eight European countries between 2006 and 2011 were included. Recurrence occurred in 336 patients. Cross-sectional (computed tomography, magnetic resonance imaging) and conventional (chest X-ray, ultrasound) methods were used in 47% and 53%, respectively. More intensive FU imaging (more than twofold) than recommended by the European Association of Urology (EAU) was not associated with improved overall survival (OS) after recurrence. Overall, per patient treated for recurrence remaining alive with no evidence of disease, the number of FU images needed was 542, and 697 for high-risk patients. The study results suggest that use of more imaging during FU than that recommended in the 2017 EAU guidelines is unlikely to improve OS after recurrence. Prospective studies are needed to design optimal FU strategies for the future.

    Patient summary: After curative treatment for localised kidney cancer, follow-up is necessary to detect any recurrence. This study illustrates that increasing the imaging frequency during follow-up, even to double the number of follow-up imaging procedures recommended by the European Association of Urology guidelines, does not translate into improved survival for those with recurrence.

    Local treatments for metastases of renal cell carcinoma: a systematic review2014Inngår i: The Lancet Oncology, ISSN 1470-2045, E-ISSN 1474-5488, Vol. 15, nr 12, s. E549-E561Artikkel, forskningsoversikt (Fagfellevurdert)
    Abstract [en]

    Local treatment of metastases such as metastasectomy or radiotherapy remains controversial in the treatment of metastatic renal cell carcinoma. To investigate the benefits and harms of various local treatments, we did a systematic review of all types of comparative studies on local treatment of metastases from renal cell carcinoma in any organ. Interventions included metastasectomy, radiotherapy modalities, and no local treatment. The results suggest that patients treated with complete metastasectomy have better survival and symptom control (including pain relief in bone metastases) than those treated with either incomplete or no metastasectomy. Nevertheless, the available evidence was marred by high risks of bias and confounding across all studies. Although the findings presented here should be interpreted with caution, they and the identified gaps in knowledge should provide guidance for clinicians and researchers, and directions for further research.

    Renal cell carcinoma recurrences and metastases in primary non-metastatic patients: a population-based study2016Inngår i: World journal of urology, ISSN 0724-4983, E-ISSN 1433-8726, Vol. 34, nr 8, s. 1081-1086Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To present the occurrence of metastases and local recurrences in primary non-metastatic patients with renal cell carcinoma (RCC) in a contemporary Swedish population-based cohort. Between 2005 and 2009, a total of 4527 patients were included in the prospective National Swedish Kidney Cancer Register accounting for nearly all RCC patients in Sweden. Among M0 patients, 472 (13 %) had no follow-up data registered within 5-year follow-up time and were excluded from the analysis. In total, 939 (21 %) had distant metastases at presentation with a decrease from 23 to 18 % during the inclusion period. Of 3107 patients with follow-up data and with M0 disease, 623 (20 %) were diagnosed with a tumor recurrence during 5-year follow-up. Mean time to recurrence was 24 months (SD +/- A 20 months). Among these, 570 patients (92 %) were at primary diagnosis treated with radical nephrectomy, 23 patients (3.7 %) with partial nephrectomy and 12 patients (1.9 %) with minimally invasive treatments. The most frequent sites of metastases were lung (54 %), lymph nodes (22 %) and bone (20 %). The treatment of recurrence was in 50 % systemic treatments, while metastasectomy was performed in 17 % of the patients, out of which 68 % were with a curative intention. In this population-based study, 21 % of the patients had metastatic disease at presentation, with a decreasing trend over the study period. During 5-year follow-up, 20 % of the primary non-metastatic patients had recurrent disease. Of the patients with recurrence, half were given systemic oncological treatment and 17 % underwent metastasectomy.
