Contains fulltext : 237261.pdf (Publisher’s version ) (Closed access) Adherence to national and international clinical practice guidelines is suboptimal throughout Europe. The European Association of Urology Guidelines Office project "IMAGINE" (IMpact Assessment of Guidelines Implementation and Education) has been developed to measure baseline adherence to urological guideline recommendations across Europe and to identify issues that drive nonadherence.

Context Worldwide, prostate cancer (PCa) represents the second most common solid tumor in men. Objective To assess the geographical distribution of PCa, epidemiological differences, and the most relevant risk factors for the disease. Evidence acquisition Estimated incidence, mortality, and prevalence of PCa for the year 2020 in 185 countries were derived from the IARC GLOBOCAN database. A review of English-language articles published between 2010 and 2020 was conducted using MEDLINE, EMBASE, and Scopus to identify risk factors for PCa. Evidence synthesis In the year 2020, there were over 1 414 000 estimated new cases of PCa worldwide, with an age-standardized rate (ASR) incidence of 31 per 100 000 (lifetime cumulative risk: 3.9%). Northern Europe has the highest all-age incidence ASR (83), while the lowest ASR was in South-Central Asia (6.3). In the year 2020, there were over 375 000 estimated deaths worldwide, and the overall mortality ASR was 7.7 per 100 000, with the highest ASR in the Caribbean (28) and the lowest in South-Central Asia (3.1). Family history, hereditary syndromes, and race are the strongest risk factors for PCa. Metabolic syndrome was associated with the risk of developing PCa, high-grade disease, and adverse pathology. Diabetes and exposure to ultraviolet rays were found to be inversely associated to PCa incidence. Cigarette smoking and obesity may increase PCa-specific mortality, while regular physical activity may reduce disease progression. Although 5-alpha reductase inhibitors are known to be associated with a reduced incidence of PCa, available studies failed to show an effect on overall mortality. Conclusions Family history, race, and hereditary syndromes are well-established risk factors for PCa. Modifiable risk factors may impact the risk of developing PCa and that of dying from the disease, but little evidence exist for any clear indication for prevention other than early diagnosis to reduce PCa mortality. Patient summary Prostate cancer (PCa) rates vary profoundly worldwide, with incidence and mortality rates being highest in Northern Europe and Caribbean, respectively. South-Central Asia has the lowest epidemiological burden. Family history, race, and hereditary syndromes are well-established risk factors for PCa. Modifiable risk factors may impact the risk of developing PCa and that of dying from the disease itself, but little evidence exist for any clear indication for prevention other than early diagnosis to reduce PCa mortality.

Background Hormonal manipulation concomitant to salvage radiotherapy (SRT) given for biochemical recurrence (BCR) after radical prostatectomy (RP) improved outcomes in two randomized trials. However, neither of these studies focused on men treated at low prostate-specific antigen (PSA) levels. Objective To test if the impact of androgen deprivation therapy (ADT) on metastasis in patients undergoing early SRT varies according to prostate cancer (PCa) features. Design, setting, and participants A total of 525 patients received SRT at PSA levels ≤2ng/ml. Outcome measurements and statistical analyses Multivariable Cox regression analyses assessed factors associated with metastasis. We tested the hypothesis that the impact of ADT varied according to the risk of metastasis. An interaction with groups (concomitant ADT vs no ADT) and the probability of distant metastasis according to a newly developed model was tested. A nonparametric curve explored the relationship between the risk of metastasis and 10-yr metastasis rates according to ADT. Results and limitations Median PSA and radiotherapy dose were 0.42ng/ml and 66Gy, respectively. Overall, 178 (34%) patients received ADT. At a median follow-up of 104 mo, 71 patients experienced metastasis. Grade group ≥4 (hazard ratio [HR]: 1.66; 95% confidence interval [CI]: 1.01–3.30), pT3b/4 (HR: 2.61; 95% CI: 1.51–4.52), and dose (HR: 0.82; 95% CI: 0.76–0.89) were associated with metastasis. The impact of ADT differed according to the risk of metastasis calculated using a multivariable model (p=0.01). This was confirmed when considering patients treated with early SRT (p=0.046), where ADT was associated with a reduction in the rate of metastasis only in eSRT; patients with more aggressive characteristics (ie, pT3b/4 and grade group ≥4, or pT3b/4 and PSA at eSRT ≥0.4ng/ml). Conclusions The beneficial effect of ADT concomitant to eSRT varied significantly according to disease characteristics, such that only men with more aggressive PCa features benefit from ADT in the eSRT setting for BCR after RP. Patient summary The oncological benefits of concomitant androgen deprivation therapy (ADT) in patients undergoing salvage radiotherapy (SRT) vary according to pathological characteristics. Only patients with more aggressive disease characteristics seemed to benefit from the use of hormonal manipulation at the time of early SRT. Conversely, the potential side effects of ADT could be spared in patients with low prostate-specific antigen levels and favorable pathological features.
