    Abstract Background: Regional differences in active surveillance (AS) uptake for prostate cancer (PC) illustrate an inequality in treatment strategies.
    Objective: To examine the association between regional differences in AS uptake and transition to radical treatment, start of androgen deprivation therapy (ADT), watchful waiting, or death.
    Design setting and participants: A Swedish population-based cohort study was conducted including men in the National Prostate Cancer Register in Sweden with low-risk or favorable intermediate-risk PC, starting AS from January 1, 2007 and continuing till December 31, 2019.
    Intervention: Regional tradition of low, intermediate, or high proportions of immediate radical treatment.
    Outcomes measurements and statistical analysis: Probabilities of transition from AS to radical treatment, start of ADT, watchful waiting, or death from other causes were assessed.
    Results and limitations: We included 13 679 men. The median age was 66 yr, median PSA 5.1 ng/ml, and median follow-up 5.7 yr. Men from regions with a high AS uptake had a lower probability of transition to radical treatment (36%) than men from regions with a low AS uptake (40%; absolute difference 4.1%; 95% confidence interval [CI] 1.0-7.2), but not a higher probability of AS failure defined as the start of ADT (absolute difference 0.4%; 95% CI -0.7 to 1.4). There were no statistically significant differences in the probability of transition to watchful waiting or death from other causes. Limitations include uncertainty in the estimation of remaining lifetime and transition to watchful waiting.
    Conclusions: A regional tradition of a high AS uptake is associated with a lower probability of transition to radical treatment, but not with AS failure. A low AS uptake suggests overtreatment.
    Patient summary: There are considerable regional differences in active surveillance (AS) uptake for prostate cancer. This study compared the outcomes of AS in different regions and found no association between AS uptake and failure of AS; it suggests that a low AS uptake indicates overtreatment.

    Abstract Objective: To examine associations between objective signs of progression (triggers) and transition from active surveillance (AS) to radical treatment for prostate cancer (PC).
    Patients and methods: This case-control study included men with low- or favourable intermediate-risk PC in the region of Halland, with data from The National Prostate Cancer Register (NPCR), Sweden, starting AS between 2008 and 2020. Cases were men who transitioned to radical treatment. For each case, 10 controls who remained in AS were selected without further matching. Triggers for transition to treatment were histopathological progression, magnetic resonance imaging (MRI) progression and increases in prostate-specific antigen (PSA) levels. We compared the probabilities for triggers between cases and controls, in 2008-2014 and 2015-2020, using logistic regression.
    Results: Amongst 846 men, we identified 98 cases in 2008-2014 and 172 cases in 2015-2020. Histopathological progression was associated with transition, most strongly in the later period (2008-2014: odds ratios [OR] 6.88, 95% confidence interval [CI] 3.69-12.80; and 2015-2020: OR 75.29, 95% CI 39.60-143.17). MRI progression was associated with transition in 2015-2020 (OR 6.38, 95% CI 2.70-15.06), whereas an increase in PSA was weakly associated with transition in the early period. The absence of triggers was associated with no transition (2008-2014: OR 0.24, 95% CI 0.15-0.40, and 2015-2020: OR 0.09, 95% CI 0.06-0.14). The probability of no trigger was 27% in cases 2015-2020.
    Conclusion: The increase in association between histopathological trigger and transition to treatment indicates increased quality of AS. Still, amongst men treated from 2015 to 2020, 27% transitioned without any trigger.

    Abstract Background: Satisfaction with nurse-led follow-up among men with prostate cancer is high. However, it is unclear whether all men are satisfied or whether there are men who would benefit from being followed by a urologist or a nurse.
    Objective: To investigate the follow-up distribution between urologists and nurses, and whether the high self-reported satisfaction with nurse-led follow-up is independent of other factors such as age or comorbidity.Design, setting, and participants:All Swedish men, ≤70 yr of age, with a low-risk prostate cancer diagnosis in 2008, answered a questionnaire 7 yr after diagnosis. The extensive questionnaire included a question on satisfaction with care, answered on a seven-point scale. Participants were divided based on whether they were followed up by a nurse, a urologist, or both.Outcome measurements and statistical analysis:Factors that could influence the level of satisfaction were identified as age, education, comorbidity, treatment, disease progression, urinary bother, level of information, and participation in treatment decision. Likelihood ratio tests from ordinal regression were used to test the null hypothesis of similar satisfaction between groups.
    Results and limitations: Out of 1288 men, 1137 (88%) answered both the question on who performed the follow-up and the question regarding satisfaction. In all, 350 men reported that they were followed up by nurses (31%), 598 (52%) by urologists, and 189 (17%) by both. No differences in satisfaction where seen between the groups. Approximately 50% were satisfied completely, regardless of who performed the follow-up. Results were not affected by age, educational level, comorbidity, treatment, disease progression, urinary bother, information, or participation in treatment decision. Limitations include the nonrandomized, retrospective design and a potential recall bias.
    Conclusions: Satisfaction with nurse-led follow-up is high, regardless of factors such as age, level of education, comorbidity, and treatment.
    Patient summary: Men with prostate cancer can be offered nurse-led follow-up on a regular basis and still maintain their satisfaction with health care.

    Abstract Importance: The long-term outcomes among men with prostate cancer (PC) whose disease is managed with active surveillance (AS) remains unknown.
    Objective: To develop a simulation model with a 30-year follow-up for men with PC managed with AS.
    Design, setting, and participants: In this cohort study, a state transition model was created using data from Prostate Cancer data Base Sweden (PCBaSe) on 23 655 men diagnosed with PC and managed with deferred treatment to estimate treatment trajectories. A simulation was performed with 100 000 men in each combination of age at diagnosis, Charlson Comorbidity Index, and PC risk with a follow-up of 30 years.
    Main outcomes and measures: Death from PC and death from other causes were estimated, and the proportion of time without active PC treatment was assessed until date of death or age 85 years.
    Results: This study included 23 655 men from PCBaSe with a median age at diagnosis of 69 years (IQR, 64-74 years). Of these, 16 177 men underwent active surveillance for PC and 7478 underwent watchful waiting. The proportion of men who were diagnosed at age 55 years and died of PC before age 85 years was 9% for very low-risk PC, 13% for low-risk PC, and 15% for intermediate-risk PC. Among men with a Charlson Comorbidity Index of 0 who were diagnosed at age 70 years, the corresponding percentages were 3%, 6%, and 7%, respectively. The mean proportion of remaining life-years without active PC treatment for men diagnosed at age 55 years was 12 of 25 years (48%) for very low-risk PC, 9 of 25 years (36%) for low-risk PC, and 7 of 25 (29%) for intermediate-risk PC. For men aged 70 years, the corresponding numbers were 10 of 13 years (77%), 9 of 13 years (66%), and 8 of 13 years (60%), respectively. Men with intermediate-risk PC who were younger than 60 years at diagnosis had a high risk of PC death (12%-15%) and fewer remaining life-years without active PC treatment (29%-33%). In contrast, men with low-risk PC who were older than 65 years at diagnosis had a lower risk of PC death (3%-5%) and more remaining life-years without active PC treatment (62%-77%).
    Conclusions and relevance: The findings of this Swedish cohort study suggest that active surveillance may be a safe strategy for disease management among men with PC who were older than 65 years at diagnosis.

    Abstract Background: A diagnosis of prostate cancer (PC) may cause psychosocial distress that worsens quality of life; however, long-term mental health outcomes are unclear.
    Objective: To determine the long-term risks of major depression and death by suicide in a large population-based cohort.
    Design, setting, and participants: This was a national cohort study of 180 189 men diagnosed with PC during 1998-2017 and 1 801 890 age-matched, population-based, control men in Sweden.
    Outcome measurements and statistical analysis: Major depression and death by suicide were ascertained from nationwide outpatient, inpatient, and death records up to 2018. Cox regression was used to compute hazard ratios (HRs) adjusted for sociodemographic factors and comorbidities. Subanalyses assessed differences by PC treatment during 2005-2017.
    Results and limitations: Men diagnosed with high-risk PC had higher relative rates of major depression (adjusted HR [aHR] 1.82, 95% confidence interval [CI] 1.75-1.89) and death by suicide (aHR 2.43, 95% CI 2.01-2.95). These associations persisted for ≥10 yr after PC diagnosis. The relative increase in major depression was lower among those treated with radiation (aHR 1.44, 95% CI 1.31-1.57) or surgery (aHR 1.60, 95% CI 1.31-1.95) in comparison to androgen deprivation therapy (ADT) alone (aHR 2.02, 95% CI 1.89-2.16), whereas the relative rate of suicide death was higher only among those treated solely with ADT (aHR 2.83, 95% CI 1.80-4.43). By contrast, men with low- or intermediate-risk PC had a modestly higher relative rate of major depression (aHR 1.19, 95% CI 1.16-1.23) and higher relative rate of suicide death at 3-12 mo after PC diagnosis (aHR 1.88, 95% CI 1.11-3.18) but not across the entire follow-up period (aHR 1.02, 95% CI 0.84-1.25). This study was limited to Sweden and will need replication in other populations.
    Conclusions: In this large cohort, high-risk PC was associated with substantially higher relative rates of major depression and death by suicide, which persisted for ≥10 yr after PC diagnosis. PC survivors need close follow-up for timely detection and treatment of psychosocial distress.
    Patient summary: In a large Swedish population, men with aggressive prostate cancer had higher long-term relative rates of depression and suicide.

    Abstract Hazard ratios (HRs) are frequently misinterpreted. We describe an easily estimated complementary measure, the difference in restricted mean survival time (RMST), that requires fewer assumptions than the HR and is more readily interpretable. Reporting RMST-based measures may benefit shared decision-making.

    Abstract Background: The Charlson Comorbidity Index is a poor predictor of mortality in men with castration resistant prostate cancer (CRPC). To improve this prediction, we created a comorbidity index based on filled prescriptions intended to be used in registry-based studies.
    Materials and methods: In a population-based cohort of men with CPRC a drug comorbidity index (DCI-CRPC) was calculated based on prescriptions filled during a 365-day period before the date of CRPC diagnosis to predict mortality. Five risk categories for men with CRPC were defined based on PSA kinetics. Mortality rates were described by Kaplan-Meier curves. The predictive ability of the DCI-CRPC was compared in univariable models to that of the original DCI, derived from men in the general population, and to that of the Charlson Comorbidity Index.
    Results: In 1,885 men with CRPC the median overall survival ranged from 3.0 years (95% confidence interval [CI] 2.8 to 3.4) in the first tertile of the DCI-CRPC, to 1.0 year (95% CI 0.9 to 1.1) in the third tertile of the DCI-CRPC. The index had higher discriminative ability (C-index 0.667) than the Charlson Comorbidity Index (C-index 0.508). The discriminative ability of the DCI-CRPC was highest in the subgroup with least aggressive cancer (C-index 0.651) and lowest in men with most aggressive cancer (C-index 0.618). The performance of the DCI-CRPC was comparable to that of the original DCI.
    Conclusion: Our newly created comorbidity index using filled prescriptions predicted death in men with CRPC better than the Charlson Comorbidity Index.

    Abstract Importance: The diagnostic activity for prostate cancer has increased during the past decades. However, the benefit and harm of the increased diagnostic activity have not been quantified in detail for a country or a large region.
    Objective: The aim of this study was to evaluate and quantify the association between increases in diagnostic activity driven by prostate-specific antigen testing and incidence of prostate cancer diagnosis, treatment, and mortality.
    Design, setting, and participants: This cohort study used the Proxy-Based Risk-Stratified Incidence Simulation Model-Prostate Cancer to examine observed data on all Swedish men with prevalent prostate cancer and compare them with a corresponding, hypothetical, simulated scenario with more restrictive diagnostic activity. All men aged 40 to 100 years living in Sweden during the time period 1996 to 2016 with incident and prevalent prostate cancer were included. The second scenario is the corresponding, hypothetical, simulated scenario where diagnostic activity remained constant as of 1996 (the beginning of the prostate-specific antigen testing era) throughout the study period.
    Exposures: High or low diagnostic activity for prostate cancer.
    Main outcomes and measures: Incidence of prostate cancer diagnosis, treatment (deferred treatment, curative treatment, and hormonal treatment), and prostate cancer mortality.
    Results: During the study period from 1996 to 2016, 188 884 men were diagnosed with prostate cancer at a median (interquartile range) age of 71 (64-77) years. Compared with the low-diagnostic activity scenario, in the high-diagnostic activity scenario, the number of men diagnosed with prostate cancer was 48% higher (423 vs 286 [95% CI, 271-302] per 100 000 men per year), 148% more men were diagnosed with low- or intermediate-risk cancer (221 vs 89 [95% CI, 73-105] per 100 000 men per year), and 108% more men received curative treatment (152 vs 73 [95% CI: 66-85] per 100 000 men per year). There were up to 15% fewer prostate cancer deaths in the scenario with high-diagnostic activity (incidence rate ratio, 0.85; 95% CI, 0.82-0.88).
    Conclusions and relevance: This study's results suggest that increased prostate-specific antigen testing and diagnostic activity are associated with a larger number of men being diagnosed with prostate cancer, predominately with low- and intermediate-risk disease. The increased diagnostic activity was associated with a 2-fold increase in curative treatment and a modest decrease in mortality.
