Abstract [en]

Background: Parenteral fluid (PF) therapy of patients in end-of-life (EOL) is controversial. The purpose of this study was to assess associations between PF, quality of the EOL care process and symptom burden in dying cancer patients, using a population-based approach.

Methods: This was a nationwide retrospective register study of all adult cancer deaths with documented information on PF in the last 24 h of life as reported to the Swedish Register of Palliative Care during a three-year period (n = 41,709). Prevalence and relief of symptoms during the last week of life as well as EOL care process quality indicators were assessed in relation to PF in those patients who had a documented decision to focus on EOL care (immediately dying, n = 23,112). Odds ratios were calculated, adjusting for place of death (hospital vs. non-hospital).

Results: PF was administered to 30.9% of immediately dying patients in hospitals compared to 6.5% outside of hospitals. PF was associated with a higher likelihood for breathlessness and nausea. In patients screened for EOL symptoms with a validated instrument, PF was inversely associated with the likelihood of complete relief of breathlessness, respiratory secretions, anxiety, nausea and pain. Several palliative care quality indicators were inversely associated with PF, including EOL conversations and prescriptions of injectable drugs as needed. These associations were more pronounced in hospitals.

Conclusions: Parenteral fluid therapy in the last 24 h of life was associated with inferior quality of the EOL care process and with increased symptom burden in imminently dying cancer patients.

Abstract [en]

Background and Objectives: Disparities between tumors arising via different sporadic carcinogenetic pathways have not been studied systematically. This retrospective multicenter cohort study evaluated the differences in the risk for non-colorectal malignancy between sporadic colorectal cancer (CRC) patients from different DNA mismatch repair status.

Methods: A retrospective European multicenter cohort study including in total of 1706 CRC patients treated between 1996 and 2019 in three different countries. The proficiency (pMMR) or deficiency (dMMR) of mismatch repair was determined by immunohistochemistry. Cases were analyzed for tumor BRAFV600E mutation, and BRAF mutated tumors were further analyzed for hypermethylation status in the promoter region of MLH1 to distinguish between sporadic and hereditary cases. Swedish and Finish patients were matched with their respective National Cancer Registries. For the Czech cohort, thorough scrutiny of medical files was performed to identify any non-colorectal malignancy within 20 years before or after the diagnosis of CRC. Poisson regression analysis was performed to identify the incidence rates of non-colorectal malignancies. For validation purposes, standardized incidence ratios were calculated for the Swedish cases adjusted for age, year, and sex.

Results: Of the 1706 CRC patients included in the analysis, 819 were female [48%], median age at surgery was 67 years [interquartile range: 60–75], and sporadic dMMR was found in 188 patients (11%). Patients with sporadic dMMR CRC had a higher incidence rate ratio (IRR) for non-colorectal malignancy before and after diagnosis compared to patients with a pMMR tumor, in both uni- (IRR = 2.49, 95% confidence interval [CI] = 1.89–3.31, p = 0.003) and multivariable analysis (IRR = 2.24, 95% CI = 1.67–3.01, p = 0.004). This association applied whether or not the non-colorectal tumor developed before or after the diagnosis of CRC in both uni- (IRR = 1.91, 95% CI = 1.28–2.98, p = 0.004), (IRR = 2.45, 95% CI = 1.72–3.49, p = 0.004) and multivariable analysis (IRR = 1.67,95% CI = 1.05–2.65, p = 0.029), (IRR = 2.35, 95% CI = 1.63–3.42, p = 0.005), respectively.

Conclusion: In this retrospective European multicenter cohort study, patients with sporadic dMMR CRC had a higher risk for non-colorectal malignancy than those with pMMR CRC. These findings indicate the need for further studies to establish the need for and design of surveillance strategies for patients with dMMR CRC.

Abstract [en]

The standard treatment of glioblastoma, an aggressive brain tumour, includes radiotherapy combined with temozolomide. Based on a randomised trial, showing five months increased survival, TTF has been introduced in the management of patients with good performance status. Data from the Swedish national quality registry for CNS tumours have been analysed for TTF usage. The results demonstrate that 65 percent of the patients accepted treatment with TTF. More than half of the treated patients interrupted treatment due to low compliance or their own wish. Median treatment time was 164 days, with a range from 0 to 774 days. There was a large variation between different regions in how many patients were offered TTF treatment. A non-significant trend to better survival was seen for the group of TTF-treated patients compared to individually matched controls. In summary, TTF is a new treatment for glioblastoma, with potential to prolong survival also in real world patients. Today, the treatment is not offered equally to all patients, despite national guidelines.

Abstract [sv]

Mål: Denna uppföljningsstudie om upplevd självbild och psykofysisk nöd/psykiska symptom baserades på en ranomiserad kontrollerad studie av konstterapi på kvinnor med bröstcancer.

Metod: Syftet var att undersöka de långsiktiga effekterna av tidsbegränsad konstterapi med hjälp av instrumenten Strukturanalys av socialt beteende (SASB) och Symptom Check List-90 (SCL-90).

Resultat: Tre anslutningskluster i SASB visade signifikanta förändringar efter terapin: Autonomt jag (kluster 1), Accepterande själv (kluster 2) och Älskande själv (kluster 3). Klusterna 2 och 3 fortsatte att förändras till förmån för interventionsgruppen vid den 5-åriga uppföljningen. Det fanns inga signifikanta skillnader i SCL-90-resultaten mellan interventionsgruppen och kontrollgruppen i uppföljningsstudien.

Betydelse av resultat: Konstterapiinterventionen var både terapeutisk och psyko-pedagogisk. Slutsatsen av denna studie är att närmar sig känslor genom tidsbegränsad konstterapi verkar ha en långvarig effekt på det vidhäftande beteende som visas i SASB-modellen efter intervention, och denna effekt förblev 5 år senare.

Abstract [en]

Objective: This follow-up study on perceived self-image and psychophysical distress/psychic symptoms was based on a ranomized contolled study of art therapy on women with breast cancer.

Method: The aim was to examine the long-term effects of time-limited art therapy using the instruments of Structural Analysis of Social Behavior (SASB) and Symptom Check List-90 (SCL-90).

Results: Three attachment clusters of the SASB showed significant changes post therapy: Autonomous self (cluster 1), Accepting self (cluster 2), and Loving self (cluster 3). Clusters 2 and 3 continued to change in favor of the intervention group at the 5-year follow-up. There were no significant differences in the SCL-90 results between the intervention group and the control group in the follow-up study.

Significance of results: The art therapy intervention was both therapeutic and psycho-educative. The conclusion of this study is that approaching emotions through time-limited art therapy seems to have a long-lasting effect on the attachment behavioral system shown in the SASB model post intervention, and this effect remained 5 years later.

Abstract [en]

Cryoprevention (CP) using ice (IC) is an effective strategy to prevent chemotherapy-induced oral mucositis (OM). However, the use of IC may cause adverse reactions and requires water of safe quality to minimize risk of serious infections. This randomized, blinded, parallel group, phase 3 trial was conducted in five Scandinavian centers. Eligible patients were diagnosed with multiple myeloma or lymphoma, scheduled to receive conditioning with high-dose chemotherapy prior to autologous hematopoietic stem cell transplantation (ASCT). Patients were assigned to cooling with IC or a novel intraoral cooling device (ICD). The primary outcome was the highest OM score during the study period, expressed as peak value on the Oral Mucositis Assessment Scale (OMAS–total). When the entire study population (n = 172) was analyzed for peak OMAS–total, the two cooling methods were equally effective. However, when the lymphoma group was analyzed separately, the ICD significantly reduced the peak OMAS–total score to a greater extent compared to IC (x̄ ± SD; 1.77 ± 1.59 vs. 3.08 ± 1.50; p = 0.047). Combined with existing evidence, the results of the present trial confirm that CP is an effective method to prevent OM.

Abstract [en]

Aims: We assessed the association between insulin resistance and blood glucose concentrations at type 2 diabetes diagnosis and future development of diabetes-related complications and mortality.

Materials and Methods: This retrospective cohort study included 864 individuals with type 2 diabetes (median age 60 years) whose fasting C-peptide and HbA1c were measured at diabetes diagnosis. The median follow-up time until death or study end was 16.4 years (interquartile range 13.3−19.6). The association between C-peptide and mortality/complications was estimated by Cox regression adjusted for sex, age at diabetes diagnosis, smoking, hypertension, BMI, total cholesterol, and HbA1c. C-peptide and HbA1c were converted to Z scores before the Cox regression analysis.

Results: An increase by one standard deviation in fasting C-peptide at diabetes diagnosis was associated with all-cause (hazard ratio [HR] 1.33; 95% confidence intervals [CI] 1.12–1.58; p = 0.001) and cancer mortality (HR 1.51; 95% CI 1.13–2.01; p = 0.005) in the fully adjusted model. An increase by one standard deviation in HbA1c at diabetes diagnosis was associated with all-cause mortality (HR 1.24; 95% CI 1.07–1.44; p = 0.005), major cardiovascular events (HR 1.20; 95% CI 1.04–1.39; p = 0.015), stroke (HR 1.36; 95% CI 1.09–1.70; p = 0.006), and retinopathy (HR 1.54; 95% CI 1.34–1.76; p < 0.0001) in the fully adjusted model.

Conclusions: Fasting C-peptide at type 2 diabetes diagnosis is an independent risk factor for total and cancer-related mortality. Thus, treatment of type 2 diabetes should focus not only on normalising blood glucose levels but also on mitigating insulin resistance.

Abstract [en]

Sex disparities in glioblastoma (GBM) have received increasing attention. Sex‐related differences for several molecular markers have been reported, which could impact on clinical factors and outcomes. We therefore analyzed data on all patients with GBM reported to the Swedish National Quality Registry for Primary Brain Tumors, according to sex, with a focus on prognostic factors and survival. All glioma patients registered during 20 years, from 1 January 1999 until 31 December 2018, with SNOMED codes 94403, 94413, and 94423, were analyzed. Chi2‐test, log‐rank test, and Kaplan–Meier analyses were performed. We identified 5243 patients, of which 2083 were females and 3160 males, resulting in a ratio of 1:1.5. We found sex related differences, with women having diagnostic surgery at a significantly higher age (p = 0.001). Women were also reported to have a worse preoperative performance status (PPS) (<0.001). There was no gender difference for the type of surgery performed. For women with radical surgery, overall survival was slightly better than for men (p = 0.045). The time period did not influence survival, neither for 1999–2005 nor 2006– 2018, after temozolomide treatment was introduced (p = 0.35 and 0.10, respectively). In the multivariate analysis including sex, age, surgery, and PPS, a survival advantage was noted for women, but this was not clinically relevant (HR = 0.92, p = 0.006). For patients with GBM; sex‐related differences in clinical factors could be identified in a population‐based cohort. In this dataset, for survival, the only advantage noted was for women who had undergone radical surgery, although this was clinically almost negligible.

Abstract [en]

INTRODUCTION: Endometrioid endometrial carcinoma is a cancer type with generally excellent prognosis when diagnosed at an early stage, but there is a subset of patients with relapsing disease in spite of early diagnosis and surgical treatment. There is a need to find prognostic markers to identify these patients with increased risk of relapse. Depth of myometrial invasion, histological grade, and presence of lymphovascular invasion are known risk factors. DNA content (ploidy) and proliferation measured as S-phase fraction (SPF) have been discussed as prognostic markers but need additional evaluation.

MATERIAL AND METHODS: We evaluated relapse-free survival (RFS) with respect to ploidy and SPF, which was analyzed by flow cytometry on fresh tumor tissue, in a cohort of 1001 women treated for stage I endometrioid endometrial carcinoma in northern Sweden during the period of 1993-2010, with a median follow up time of 12.0 years. Data were obtained from historical records.

RESULTS: In simple analysis, both aneuploidy and high SPF were associated to increased risk of relapse with hazard ratios (HR) 2.37 (95% CI 1.52-3.70) and 1.94 (95% CI 1.24-3.02), respectively. Our data also confirmed stage, tumor grade, and ploidy as independent prognostic markers in an age adjusted cox regression multivariable analysis but we did not find SPF to contribute to prognosis. However, the combination of aneuploidy and high SPF identified a group of patients with increased risk of relapse, HR 2.02 (95% CI 1.19-3.44).

CONCLUSION: In this study, which is the largest study of ploidy and SPF in stage I endometrioid endometrial carcinoma using fresh frozen tissue, aneuploidy was shown to be an independent prognostic marker. Furthermore, the combination of aneuploidy and high SPF could be used to identify patients with increased risk of relapse.

Abstract [en]

Background: Hodgkin lymphoma (HL) patients have a good prognosis after adequate treatment. Previous treatment with mantle field irradiation has been accompanied by an increased long-term risk of cardiovascular disease (CVD). This study identified co-morbidity factors for the development of cardiovascular side effects and initiated an intervention study aimed to decrease morbidity and mortality of CVD in HL survivors.

Design: Hodgkin lymphoma patients aged ≤45 years diagnosed between 1965 and 1995 were invited to participate. In total, 453 patients completed a questionnaire that addressed co-morbidity factors and clinical symptoms. Of these, 319 accepted to participate in a structured clinical visit. The statistical analyses compared individuals with CVD with those with no CVD.

Results: Cardiovascular disease was reported by 27.9%. Radiotherapy (odds ratio [OR]: 3.27), hypertension and hypercholesterolemia were shown to be independent risk factors for the development of CVD. The OR for CVD and valve disease in patients who received radiotherapy towards mediastinum was 4.48 and 6.07, respectively. At clinical visits, 42% of the patients were referred for further investigation and 24% of these had a cardiac ultrasound performed due to previously unknown heart murmurs.

Conclusion: Radiotherapy towards mediastinum was an independent risk factor for CVD as well as hypercholesterolemia and hypertension. A reasonable approach as intervention for this cohort of patients is regular monitoring of hypertension and hypercholesterolemia and referral to adequate investigation when cardiac symptoms appear. Broad knowledge about the side effects from radiotherapy in the medical community and well-structured information regarding late side effects to the patients are all reasonable approaches as late effects can occur even 40 years after cancer treatment.

Abstract [en]

No reliable, non-invasive biomarker of metastatic breast cancer (mBC) exists: circulating CA15-3 (cCA15-3) is the marker mostly used to monitor mBC. Circulating collagen IV (cCOLIV) has been evaluated in other metastatic cancers and has been found to be a promising biomarker. The overarching aim of this study was to evaluate cCOLIV as a potential biomarker in patients with mBC. The first aim was to determine the levels of cCOL IV and cCA15-3 in patients with healthy controls, primary breast cancer (pBC) and mBC. The second aim was to compare levels of cCOLIV and cCA15-3 in patients with different metastatic sites of BC. The third aim was to investigate the prognostic value of cCOLIV and cCA15-3 for mBC patients. The fourth aim was to analyse whether a combination of the two biomarkers was more accurate in detecting mBC than a single marker. Lastly, we investigated the tissue expression levels of COLIV in BC bone metastases (BM) and liver metastases (LM). Plasma levels of cCOLIV and cCA15-3 from healthy controls and patients with pBC and mBC were measured. COLIV expression in tissue from patients with LM and BM was analysed using immunohistochemistry. Clinical and survival data were collected from medical charts. The levels of cCOLIV and cCA15-3 were significantly elevated in mBC patients compared with healthy controls and pBC patients. No differences in cCOLIV and cCA15-3 levels were found based on the metastatic site. High levels of cCOLIV, but not cCA15-3, correlated with poorer survival. cCOLIV alone and the combination of cCA15-3 and cCOLIV were superior to cCA15-3 at detecting mBC. COL IV was highly expressed in the tissue of LM and BM. Our study suggests that cCOLIV is a potential marker to monitor patients with BC.
