Purpose: Radiation therapy (RT) causes tissue damage and inflammation. Because cytokines play a key role in such processes, their expression levels can be an indicator of cell and tissue toxicity. This critical review aims to explore whether levels of circulating inflammatory biomarkers in peripheral blood are associated with proton- or photon-based therapy in the pelvic area and how these levels vary over time. Further, we investigated whether these levels can be linked to radiation dose, the incidence of toxicity, and changes in toxicity over time.

Methods and Materials: A literature search was conducted in PubMed to find studies involving comparative cohorts of pelvic irradiated patients with cancer. Studies reporting on the association of markers in peripheral blood with inflammatory processes and/or toxicity were included.

Results: We found evidence of associations between changes in inflammatory cytokine levels and the total cumulative dose-volume together with RT-induced toxicity in patients with cancer treated with pelvic RT. Common patient-reported outcomes demonstrate an association between radiation toxicity (eg, genitourinary toxicity) and circulating inflammatory biomarker levels.

Conclusions: This review highlights that the total cumulative dose and irradiated tissue volume are the primary drivers of RT-induced biomarker expression, influencing both early and late toxicity outcomes. The diversity in RT techniques, total dose, and number of treatment sessions across studies likely contributes to the variation in observed results. Circulating cytokine and biomarker levels in the blood can provide valuable monitoring and predictive insights for patients undergoing proton- or photon-based RT of the pelvis. Biomarker analysis in the context of RT offers clinical value by enabling personalized treatment by helping predict which patients are at higher risk for certain toxicities, guiding clinicians in tailoring treatment, optimizing supportive care, and adjusting RT plans. This approach could improve patient outcomes and quality of life by reducing long-term complications from radiation exposure.

Background: In the fast-expanding field of life-prolonging-treatment of metastatic, castration-resistant prostate cancer, treatment decision-making is very complex - both for patients and healthcare professionals since there is no “one size that fits all” in choosing treatment in this phase. Little research has been conducted about men’s experiences of treatment decision-making in this advanced, incurable, phase. Hence, this study aimed to describe men’s experiences of decision-making in life-prolonging treatments of metastatic castration-resistant prostate cancer.

Methods: Seventeen men were recruited from four oncology clinics in Sweden and interviewed at baseline. Qualitative interviews (n = 31) were conducted over two years, the timepoints for subsequent interviews (10 men were interviewed twice or more) adhered to when each man switched or terminated life-prolonging treatment. Data was analysed with qualitative content analysis.

Results: Initially, the men were adamant about proceeding with treatment. As their illness continued to progress, they gradually turned their focus more towards their well-being. They wished for continuity regarding treating physicians and constantly being assigned new physicians compromised the quality of care and complicated decision-making. In their decision-making, the men adapted their own approach to the approach taken by their physician, even if it was not an approach they had originally preferred. They wished for their role preferences to be respected. Most men had made treatment decisions collaboratively with their physician, but some described having taken on a more, or less, driving role in decision-making than they really wished for. Navigating healthcare was perceived as difficult and for some it thus felt necessary to pursue and coordinate their own care by e.g. using personal connections or contacting clinics ahead of referral. A part of treatment decision-making was forming a basis for a decision, in which the need for personalized information (quality, quantity and timing) came forth as important.

Conclusions: When diagnosed with metastatic castration-resistant prostate cancer, men’s preferences for their decision-making role, and perspectives on the treatment outcome need to be continuously addressed throughout their disease course. Improved continuity of care and a more personalised care approach should meet these patients’ wishes and needs in this phase.

Background: Fatigue may significantly effect everyday- and working life for radiotherapy patients. Some studies indicate a correlation between radiation dose and irradiated volume of the brain and the presence of fatigue. Our hypothesis was that patient reported outcome measures (PROMs) can improve our understanding of the patients’ symptoms following proton beam therapy (PBT) and optimize PBT for future patients.

Methods: This study included 167 adult patients (>18 years) who received PBT for malignant brain tumours. Data on dose metrics to intra-cranial structures was obtained from PBT treatment plans. To explore fatigue and health related quality of life (HRQoL); Multidimensional Fatigue Inventory (MFI-20) and EORTC QLQ-C30 was used at 6-, 12-, 24- and 36 months post PBT. The correlation between fatigue and dosimetry was explored using Spearman's signed rank test.

Results: No severe fatigue was recorded during the 36 months follow-up. Correlations between higher radiation dose and worsened fatigue scores were generally weak (rho < 0.3). At 12 months post PBT, higher mean dose to the brain, brainstem, hippocampi and pituitary was correlated to worsened MFI Physical Fatigue. Further, Reduced Motivation according to MFI was correlated to higher radiation dose to the brainstem and the pituitary gland. At 36 months follow-up post-PBT, both Reduced Activity and Reduced motivation according to MFI were correlated to higher radiation dose to the brain, brainstem and hippocampi.

Conclusion: Proton beam therapy are well tolerated, with similar degree of fatigue pre- and post PBT. Achieving further reduction in mean brain dose appears beneficial.

Objectives: Despite rapid expansion of treatments for metastatic castration-resistant prostate cancer (mCRPC) and the importance of symptom management for enhancing quality of life, few studies have focused on men's experiences of symptom burden over time when receiving one or more lines of treatment in a real-world situation in this phase. The aim was to investigate changes in the multidimensional symptom burden during the first year of life-prolonging treatment of mCRPC.

Methods: Longitudinal data from the first year of life-prolonging treatment for 134 men with mCRPC were used. Symptoms were measured with the multidimensional Memorial Symptom Assessment Scale. Data are presented with descriptive statistics, and changes in symptom burden (physical, psychological and number of symptoms) were analysed using linear mixed modelling.

Results: On average, the men had approximately 10 (0-31) symptoms at inclusion and 12 (0-33) at the last time point. Lack of energy and sweats were the two most reported symptoms at every time point. Sexual problems had the highest scores in all dimensions (frequency, severity, distress). Regarding pain, the distress score was higher than the scores for frequency and severity at t1-t4. Physical symptom burden and the number of symptoms changed significantly over time, towards a higher symptom burden. Psychological symptom burden did not change significantly over time.

Conclusion: The different dimensions of physical symptoms in men treated for mCRPC need to be more acknowledged. Early integration of a palliative care approach could possibly help in enhancing symptom management and quality of life for these men.

Background and purpose: For the most advanced stage of metastatic castration-resistant prostate cancer (mCRPC), several life-prolonging treatments have become available over the past decade. Treatment decision-making (TDM) and experiences in this phase are yet to be studied. Hence, this study aimed to describe men’s satisfaction with TDM and treatment experiences during the first 12 months of a life-prolonging treatment of mCRPC.

Patients and methods: This prospective study included 104 men with mCRPC who started and remained on the same life-prolonging treatment for 12 months. They received a questionnaire on TDM, treatment experiences, and well-being every 3 months. Correlation analyses explored associations between satisfaction with TDM at baseline and treatment experiences and well-being over time.

Results and interpretation: The participants (median age: 77 years) generally reported high satisfaction with physician-and nurse communication and confidence/trust at baseline (>55% reported the highest satisfaction in all questions), but lower satisfaction with communication regarding how the treatments could affect them – up to 40% reported not having talked about that at all. Treatment experiences and physical-and emotional well-being remained stable over time. Associations were found between satisfaction with TDM at baseline and how they rated the treatment as a whole at six months, and well-being at six and 12 months. In mCRPC, men’s TDM preferences need to be explored, and shared decision-making needs to be facilitated when considering treatment. Furthermore, clinicians need to discuss how the treatment might affect patients’ everyday lives when discussing life-prolonging treatments with them.

Purpose: Nurses are particularly at risk for occupational exposure to hazardous cancer drugs, risking both acute and chronic health effects. Knowledge on the implemented safety precautions into minimizing these risks is limited.

Methods: The European Cancer Nursing Index (ECNI) was developed by the European Oncology Nursing Society (EONS) to illustrate the development and status of this profession. In this study, anonymous online survey data on occupational safety reported by European cancer nurses as part of the ECNI 2022, was analysed.

Results: A total of 630 cancer nurses from 29 countries responded to the survey. A majority reported that written guidelines (n = 553, 88%) on safe handling and administration of hazardous drugs, personal protection equipment (PPE) and cytotoxic spillage kits (n = 514, 82%) were available at their workplaces. 130 (21%) nurses reported that wipe testing to assess any residual hazardous drugs on workplace surfaces were conducted systematically at their workplaces. 185 (29%) nurses reported that nurses sometimes or always continued with their regular tasks (including handling hazardous cancer drugs) during pregnancy and breast feeding. 185 (29%) also responded that nurses at their workplaces did not receive an introductory education program before handling hazardous drugs. In total, 346 (55%) of the nurses reported that their workplace had a freedom to speak-up guardian or whistle blower policy for members of staff.

Conclusions: Even if most nurses report that there are safety routines in place at their workplaces, the results reveal several serious occupational risks for European nurses handling hazardous cancer drugs. Actions are needed to improve and optimize occupational safety for nursing staff.

Background: This study assessed the cost-effectiveness of proton beam therapy (PBT) compared to conventional radiotherapy (CRT) for treating patients with brain tumors in Sweden.

Methods: Data from a longitudinal non-randomized study performed between 2015 and 2020 was used, and included adult patients with brain tumors, followed during treatment and through a one-year follow-up. Clinical and demographic data were sourced from the longitudinal study and linked to Swedish national registers to get information on healthcare resource use. A cost-utility framework was used to evaluate the cost-effectiveness of PBT vs. CRT. Patients in PBT group (n = 310) were matched with patients in CRT group (n = 40) on relevant observables using propensity score matching with replacement. Costs were estimated from a healthcare perspective and included costs related to inpatient and specialized outpatient care, and prescribed medications. The health outcome was quality-adjusted life-years (QALYs), derived from the EORTC-QLQ-C30. Generalized linear models (GLM) and two-part models were used to estimate differences in costs and QALYs.

Results: PBT yielded higher total costs, 14,639 US$, than CRT, 13,308 US$, with a difference of 1,372 US$ (95% CI, -4,914–7,659) over a 58 weeks’ time horizon. Further, PBT resulted in non-significantly lower QALYs, 0.746 compared to CRT, 0.774, with a difference of -0.049 (95% CI, -0.195–0.097). The probability of PBT being cost-effective was < 30% at any willingness to pay.

Conclusions: These results suggest that PBT cannot be considered a cost-effective treatment for brain tumours, compared to CRT.

Trial registration: Not applicable.

Background: Patients with advanced pancreatic cancer have limited survival and few treatment options. We studied whether mistletoe extract (ME), in addition to comprehensive oncological treatment and palliative care, prolongs overall survival (OS) and improves health-related quality of life (HRQoL).

Methods: The double-blind, placebo-controlled MISTRAL trial was conducted in Swedish oncology centers. The main inclusion criteria were advanced exocrine pancreatic cancer and Eastern Cooperative Oncology Group (ECOG) performance status 0–2. The subjects were randomly assigned to ME (n=143) or placebo (n=147) and were stratified by study site and by eligibility (yes/no) for palliative chemotherapy (June 2016–December 2021). ME or placebo was injected subcutaneously three times a week for nine months. The primary endpoint was overall survival (OS); one of the secondary endpoints was the HRQoL dimension global health/ QoL (EORTC–QLQ–C30), as assessed at seven time points over nine months.

Trial registration: EudraCT 2014–004552–64, NCT02948309

Results: No statistically significant benefit of adding ME to standard treatment was seen with respect to either OS or global health/ QoL. The adjusted hazard ratio for OS was 1.13 [0.89; 1.44], with a median survival time of 7.8 and 8.3 months for ME and placebo, respectively. The figures for the HRQoL dimension “global health/QoL” were similar in the two groups (p=0.86). The number, severity, and outcome of the reported adverse events were similar as well, except for more common local skin reactions at ME injection sites (66% vs. 1%).

Conclusion: ME is unlikely to have a clinically significant effect on OS or the HRQoL dimension global health/QoL when administered in patients with advanced pancreatic cancer in addition to comprehensive cancer care.

BACKGROUND: Data on functional and psychological side effects following curative treatment for prostate cancer are lacking from large, contemporary, unselected, population-based cohorts.

OBJECTIVE: To assess urinary symptoms, bowel disturbances, erectile dysfunction (ED), and quality of life (QoL) 12 mo after robot-assisted radical prostatectomy (RARP) and radiotherapy (RT) using patient-reported outcome measures in the Swedish prostate cancer database.

DESIGN, SETTING, AND PARTICIPANTS: This was a nationwide, population-based, cohort study in Sweden of men who underwent primary RARP or RT between January 1, 2018 and December 31, 2020.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Absolute proportions and odds ratios (ORs) were calculated using multivariable logistic regression, with adjustment for clinical characteristics.

RESULTS AND LIMITATIONS: A total of 2557 men underwent RARP and 1741 received RT. Men who underwent RT were older (69 vs 65 yr) and had more comorbidities at baseline. After RARP, 13% of men experienced incontinence, compared to 6% after RT. The frequency of urinary bother was similar, at 18% after RARP and 18% after RT. Urgency to defecate was reported by 14% of men after RARP and 34% after RT. At 1 yr, 73% of men had ED after RARP, and 77% after RT. High QoL was reported by 85% of men after RARP and 78% of men after RT. On multivariable regression analysis, RT was associated with lower risks of urinary incontinence (OR 0.25, 95% confidence interval [CI] 0.19-0.33), urinary bother (OR 0.79, 95% CI 0.66-0.95), and ED (OR 0.54, 95% CI 0.46-0.65), but higher risk of bowel symptoms (OR 2.86, 95% CI 2.42-3.39). QoL was higher after RARP than after RT (OR 1.34, 95% CI 1.12-1.61).

CONCLUSIONS: Short-term specific side effects after curative treatment for prostate cancer significantly differed between RARP and RT in this large and unselected cohort. Nevertheless, the risk of urinary bother was lower after RT, while higher QoL was common after RARP.

PATIENT SUMMARY: In our study of patients treated for prostate cancer, urinary bother and overall quality of life are comparable at 1 year after surgical removal of the prostate in comparison to radiotherapy, despite substantial differences in other side effects.

Background: The Head and Neck Patient Symptom Checklist (HNSC) is a validated 2-part instrument used to ask patients with head and neck cancer about the nutrition impact symptoms they experience (part 1) and how these interfere with their eating (part 2).

Purpose:The purpose of this work was to translate and culturally adapt the HNSC into Swedish in accordance with the guidelines of the International Society for Health Economics and Outcomes Research (ISPOR).

Methods:The ISPOR guidelines include 10 steps, and these were thoroughly followed. In step 7, 9 health care professionals from the field of head and neck cancer assessed the perceived relevance (content validity) of each item in the HNSC, as well as the full HNSC. A total of 522 participants with head and neck cancer were included and followed up on 7 occasions using the HNSC to assess internal consistency.

Results:The HNSC was translated from English into Swedish, ensuring accuracy through forward and backward translation and harmonization in the research team. Content validity for each part of the HNSC was rated excellent (scale content validity index 0.96). Internal consistency demonstrated a good Cronbach’s alpha score (>0.8) across the 7 follow-up time points (from baseline [before the start of treatment] and up to 24 months posttreatment).

Conclusions:The HNSC has been successfully translated and culturally adapted into Swedish. The HNSC can be used in both clinical practice and research to screen for nutrition impact symptoms and symptoms that interfere with eating in patients with head and neck cancer.
