- Aims: We aimed to develop a European Organization for Research and Treatment of Cancer (EORTC) Quality of Life (QoL) module tailored for patients with advanced (resectable or unresectable stage III/IV) melanoma receiving immune checkpoint inhibitors or targeted therapy. Methods: Following the EORTC QoL Group module development guidelines, we conducted phases 1 and 2 of the development process. In phase 1, we generated a list of health-related (HR)QoL issues through a systematic literature review and semi-structured interviews with healthcare professionals (HCPs) and patients with advanced melanoma. In phase 2, these issues were converted into questionnaire items to create the preliminary module. Results: Phase 1: we retrieved 8006 articles for the literature review, of which 35 were deemed relevant, resulting in 84 HRQoL issues being extracted to create the initial issue list. Semi-structured interviews with 18 HCPs and 28 patients with advanced melanoma resulted in 28 issues being added to the initial issue list. Following EORTC module development criteria, 26 issues were removed, and two issues were added after review by patient advocates. Phase 2: To ensure uniformity and avoid duplication, 16 issues were consolidated into eight items. Additionally, an independent expert contributed one new item, resulting in a preliminary module comprising 80 HRQoL items. Conclusion: We identified a range of HRQoL issues (dry skin, xerostomia, and arthralgia) relevant to patients with stage III/IV melanoma. Future module development phases will refine the questionnaire. Once completed, this module will enable standardized assessment of HRQoL in patients with (locally) advanced melanoma.

- Purpose: The purpose of this study is to develop a European Organisation for Research and Treatment of Cancer Quality of Life Group (EORTC QLG) questionnaire that captures the full range of physical, mental, and social health-related quality of life (HRQOL) issues relevant to disease-free cancer survivors. In this phase III study, we pretested the provisional core questionnaire (QLQ-SURV111) and aimed to identify essential and optional scales. Methods: We pretested the QLQ-SURV111 in 492 cancer survivors from 17 countries with one of 11 cancer diagnoses. We applied the EORTC QLG decision rules and employed factor analysis and item response theory (IRT) analysis to assess and, where necessary, modify the hypothesized questionnaire scales. We calculated correlations between the survivorship scales and the QLQ-C30 summary score and carried out a Delphi survey among healthcare professionals, patient representatives, and cancer researchers to distinguish between essential and optional scales. Results: Fifty-four percent of the sample was male, mean age was 60 years, and, on average, time since completion of treatment was 3.8 years. Eleven items were excluded, resulting in the QLQ-SURV100, with 12 functional and 9 symptom scales, a symptom checklist, 4 single items, and 10 conditional items. The essential survivorship scales consist of 73 items. Conclusions: The QLQ-SURV100 has been developed to assess comprehensively the HRQOL of disease-free cancer survivors. It includes essential and optional scales and will be validated further in an international phase IV study. Implications for Cancer Survivors: The availability of this questionnaire will facilitate a standardized and robust assessment of the HRQOL of disease-free cancer survivors.

- Background Men with prostate cancer (PCa) on gonadotropin-releasing hormone agonists (GnRH) have an increased risk of cardiovascular disease (CVD) compared to men with PCa not on GnRH as well as compared with PCa-free men. Whether the addition of androgen receptor targeted (ART) drugs to GnRH further increases CVD risk, remains to be fully elucidated. Material and methods We investigated risk of CVD for men with castration resistant PCa (CRPC) on GnRH plus ART; abiraterone or enzalutamide vs 5,127 and 12,079 respective matched comparator men on GnRH in Prostate Cancer data Base Sweden (PCBaSeTraject) 4.1 between 1 June 2015 and 31 December 2018. PCBaSeTraject links National Prostate Cancer Register of Sweden to other healthcare registries and demographic databases. We conducted multivariable Cox proportional hazard models adjusting for PCa risk category, Charlson comorbidity index (CCI), insulin or statin use, civil status, level of education, history of CVD events and number of CVD drugs, with any incident or fatal CVD as the outcome. Results and conclusion 1,310 men were treated with abiraterone and 3,579 with enzalutamide. In multivariable analysis, CVD risk was increased in men on abiraterone (hazard ratio (HR): 1.19; 95% confidence interval (CI): 1.03-1.38) and in men on enzalutamide (HR: 1.10; 95% CI: 1.01-1.20). Men with a recent CVD (<12 months) including both men on ART as well as comparators had a much higher probability of a new CVD vs men with no prior CVD. CVD risk was mildly increased in men with PCa on GnRH plus abiraterone or enzalutamide vs comparator men on GnRH. Residual confounding and detection bias may at least partly explain this association.

- Type 2 diabetes mellitus (T2DM) has consistently been associated with decreased risk of prostate cancer; however, if this decrease is related to the use of anti-diabetic drugs is unknown. We prospectively studied men in the comparison cohort in the Prostate Cancer data Base Sweden 3.0, with data on T2DM, use of metformin, sulfonylurea and insulin retrieved from national health care registers and demographic databases. Cox proportional hazards regression models were used to compute hazard ratios (HR) and 95% confidence intervals (CI) of prostate cancer, adjusted for confounders. The study consisted of 612,846 men, mean age 72 years (standard deviation; SD = 9 years), out of whom 25,882 men were diagnosed with prostate cancer during follow up, mean time of 5 years (SD = 3 years). Men with more than 1 year's duration of T2DM had a decreased risk of prostate cancer compared to men without T2DM (HR = 0.85, 95% CI = 0.82-0.88) but among men with T2DM, those on metformin had no decrease (HR = 0.96, 95% CI = 0.77-1.19), whereas men on insulin (89%) or sulfonylurea (11%) had a decreased risk (HR = 0.73, 95% CI = 0.55-0.98), compared to men with T2DM not on anti-diabetic drugs. Men with less than 1 year's duration of T2DM had no decrease in prostate cancer risk (HR = 1.11, 95% CI = 0.95-1.31). Our results gave no support to the hypothesis that metformin protects against prostate cancer as recently proposed. However, our data gave some support to an inverse association between T2DM severity and prostate cancer risk.

- In the last decade, active surveillance (AS) has emerged as an acceptable choice for low-risk prostate cancer (PC), however there is discordance amongst large AS cohort studies with respect to entry and monitoring protocols. We systematically reviewed worldwide AS practices in studies reporting =5 years follow-up. We searched PubMed and Medline 2000-now and identified 13 AS cohorts. Three key areas were identified: (I) patient selection; (II) monitoring protocols; (III) triggers for intervention-(I) all studies defined clinically localised PC diagnosis as T2b disease or less and most agreed on prostate-specific antigen (PSA) threshold ( < 10 μg/L) and Gleason score threshold (3+3). Inconsistency was most notable regarding pathologic factors (e.g., number of positive cores); (II) all agreed on PSA surveillance as crucial for monitoring, and most agreed that confirmatory biopsy was required within 12 months of initiation. No consensus was reached on optimal timing of digital rectal examination (DRE), general health assessment or re-biopsy strategies thereafter; (III) there was no universal agreement for intervention triggers, although Gleason score, number or percentage of positive cancer cores, maximum cancer length (MCL) and PSA doubling time were used by several studies. Some also used imaging or re-biopsy. Despite consistent high progression-free/cancer-free survival and conversion-to-treatment rates, heterogeneity exists amongst these large AS cohorts. Combining existing evidence and gathering more long-term evidence [e.g., the Movember's Global AS database or additional information on use of magnetic resonance imaging (MRI)] is needed to derive a broadly supported guideline to reduce variation in clinical practice. © Translational Andrology and Urology.

- Context: Despite support for active surveillance (AS) as a first treatment choice for men with low-risk prostate cancer (PC), this strategy is largely underutilised. Objective: To systematically review barriers and facilitators to selecting and adhering to AS for low-risk PC. Evidence acquisition: We searched PsychINFO, PubMed, Medline 2000-now, Embase, CINAHL, and Cochrane Central databases between 2002 and 2017 using the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. The Purpose, Respondents, Explanation, Findings and Significance (PREFS) and Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) quality criteria were applied. Forty-seven studies were identified. Evidence synthesis: Key themes emerged as factors influencing both choice and adherence to AS: (1) patient and tumour factors (age, comorbidities, knowledge, education, socioeconomic status, family history, grade, tumour volume, and fear of progression/side effects); (2) family and social support; (3) provider (speciality, communication, and attitudes); (4) healthcare organisation (geography and type of practice); and (5) health policy (guidelines, year, and awareness). Conclusions: Many factors influence men's choice and adherence to AS on multiple levels. It is important to learn from the experience of other chronic health conditions as well as from institutions/countries that are making significant headway in appropriately recruiting men to AS protocols, through standardised patient information, clinician education, and nationally agreed guidelines, to ultimately decrease heterogeneity in AS practice. Patient summary: We reviewed the scientific literature for factors affecting men's choice and adherence to active surveillance (AS) for low-risk prostate cancer. Our findings suggest that the use of AS could be increased by addressing a variety of factors such as information, psychosocial support, clinician education, and standardised guidelines.

- Objectives To study whether androgen deprivation therapy (ADT), the mainstay treatment for advanced and disseminated prostate cancer, is associated with risk of dementia. Methods Risk of dementia in men with prostate cancer primarily managed with ADT or watchful waiting (WW) in the Prostate Cancer Database Sweden, PCBaSe, was compared with that in prostate cancer-free men, matched on birth year and county of residency. We used Cox regression to calculate the hazard ratios (HRs) for Alzheimer's and non-Alzheimer's dementia (vascular dementia, dementia secondary to other diseases or unspecified dementias) for different types and duration of ADT and oral antiandrogens (AAs) as well as for men managed with WW. Results A total of 25 967 men with prostate cancer and 121 018 prostate cancer-free men were followed for a median of 4 years. In both groups 6% of the men were diagnosed with dementia. In men with prostate cancer, gonadotropin-releasing hormone agonist treatment ( HR 1.15, 95% confidence interval [CI] 1.07-1.23) and orchiectomy (HR 1.60, 95% CI 1.32-1.93) were associated with an increased risk of dementia, as compared to no treatment in prostate cancer-free men; however, this increase in risk was only observed for non-Alzheimer's dementia and occurred from year 1-4 after start of ADT. No increase in risk for any type of dementia was observed for men treated with AAs or for men on WW. Conclusion This population-based cohort study does not support previous observations of an increased risk of Alzheimer's dementia for men on ADT; however, there was a small increase in risk of non-Alzheimer's dementia.

- Introduction and objectives Bladder cancer is primarily a disease of older age and little is known about the differences between patients diagnosed with bladder cancer at a younger versus older age. Our objectives were to compare bladder cancer specific survival in patients aged Materials and methods The Swedish bladder cancer database provided data on patient demographics, clinical characteristics and treatments for this observational study. Cox proportional hazard regression models were adjusted for appropriate variables. All analyses were stratified by disease stage (non-muscle-invasive bladder cancer and muscle-invasive bladder cancer. Furthermore, we compared the frequency of lower urinary tract infections within 24 months prior to bladder cancer diagnosis by sex and age groups. Results The study included 15,452 newly-diagnosed BC patients (1997-2014); 1,207 (8%) patients were <50 whilst 14,245 (92%) were aged 50-70. Patients aged <50 at diagnosis were at a decreased risk of bladder cancer death (HR = 0.82, 95%CI: 0.68-0.99) compared to those aged 50-70. When stratified by non-muscle-invasive and muscle-invasive bladder cancer, this association remained in non-muscle-invasive patients only (<50, HR = 0.43, 95% CI: 0.28-0.64). The frequency of lower urinary tract infection diagnoses did not differ between younger and older patients in either men or women. Conclusions Patients diagnosed with non-muscle-invasive bladder cancer when aged <50 are at decreased risk of bladder cancer-specific death when compared to their older (50-70) counterparts. These observations raise relevant research questions about age-related differences in diagnostic procedures, clinical decision-making and, not least, potential differences in tumour biology.
