In this trial, investigators tested the effect of prostate-specific–antigen testing on the death rate from prostate cancer in more than 162,000 men between the ages of 55 and 69 years in seven European countries. A significant reduction in prostate-cancer mortality was found after a median follow-up of 9 years. Overdiagnosis and overtreatment were important limitations of the screening program. Measurement of serum prostate-specific antigen (PSA), a biomarker for prostate cancer, 1 is useful for the detection of early prostate cancer. 2 Nevertheless, the effect of PSA-based screening on prostate-cancer mortality remains unclear. 3 The European Randomized Study of Screening for Prostate Cancer (ERSPC) was initiated in the early 1990s to determine whether a reduction of 25% in prostate-cancer mortality could be achieved by PSA-based screening. 4 Preliminary data from this study have been published and can be accessed at www.erspc.org. Another randomized screening trial in the United States, the Prostate, Lung, Colon, and Ovarian (PLCO) Cancer Screening Trial, was initiated around the same . . .

Prostate cancer is the most common malignant disease in men. Several therapeutic agents have been approved during the last 10 years. Among them, radium-223 dichloride (Xofigo ) is a radioactive isotope that induces irreversible DNA double-strand breaks and consequently tumor cell death. Radium-223 dichloride is a calcium-mimetic agent that specifically targets bone lesions. Radium-223 dichloride has been approved for the treatment of metastatic castration-resistant prostate cancer with symptomatic bone metastases, without known visceral metastases. In this review, first we summarize the interplay between prostate tumor cells and bone microenvironment; then, we discuss radium-223 dichloride mechanism of action and present the results of the available clinical trials and future developments for this new drug.

Background Although prostate cancer (PCa) is the most frequent male cancer in industrialized countries, little is known about its aetiology. The literature has suggested an influence of the environment, including occupational exposures, but results are inconsistent. In this context, we investigated PCa risk associated to employment among several occupations using data from EPICAP study. Methods EPICAP is a French population-based case-control study including 819 PCa incident cases and 879 controls frequency-matched on age. In-person interviews gathered data on potential risk factors and lifetime occupational histories for each job held at least 6 months. Then, occupations were coded using ISCO 68. Unconditional logistic regressions were performed to assess the association between occupations (ever occupied and by duration) and PCa risk, whether all and aggressive, after adjusting for potential confounders. Results For ≥10 years of employment, we found positive associations with PCa, whether overall and aggressive, among Medical, Dental and Veterinary workers (OR (odds ratios) =5.01 [95% confidence interval] [1.27; 19.77]), Members of the armed forces (OR = 5.14 [0.99; 26.71]) and Fishermen, hunters and related workers (OR = 4.58 [1.33; 15.78]); whether overall and non-aggressive PCa, among Legislative officials and Government administrators (OR = 3.30 [1.10; 9.84]) or Managers (OR = 1.68 [1.18; 2.41]); however a negative association, whether overall and non-aggressive PCa, among Material-Handling and Related Equipment Operators, Dockers and Freight Handlers (OR = 0.40 [0.17; 0.97]). Conclusion Excess PCa risks were observed in the EPICAP study mostly among white collar workers exposed to several factors in their work environment. These emerging associations can be used to lead future research investigating specific occupational exposures.

SCs for the circulating rumor antigens mucin 1 (MUC1) or prostate-specific antigen (PSA) were detected in the majority of patiente with metastatic breast (100%) and prostate (83.3%) cancer, respectively, whereas such SCs were not observed in healthy controls or in patients with benign prostatic hyperplasia (2). Consistent with our previous findings, the EPISPOT assay revealed viable DTC in the peripheral blood of 65% of prostate cancer patients, even in the absence of overt metastases (stage M^sub 0^) (2), but the number of PSA-SCs in localized prostate cancer patients (median, 9; range, 2-197) was significantly lower (P = 0.01) than in patients with metastatic cancer (median, 29; range, 1-684), a finding that is in accordance with the different disease stages and total tumor burdens.

PurposeBladder cancer is a complex disease with a wide range of outcomes. Clinicopathological factors only partially explain the variability between patients in prognosis and treatment response. There is a need for large cohorts collecting extensive data and biological samples to: (1) investigate gene-environment interactions, pathological/molecular classification and biomarker discovery; and (2) describe treatment patterns, outcomes, resource use and quality of life in a real-world setting.ParticipantsCOBLAnCE (COhort to study BLAdder CancEr) is a French national prospective cohort of patients with bladder cancer recruited between 2012 and 2018 and followed for 6 years. Data on patient and tumour characteristics, treatments, outcomes and biological samples are collected at enrolment and during the follow-up.Findings to dateWe describe the cohort at enrolment according to baseline surgery and tumour type. In total, 1800 patients were included: 1114 patients with non-muscle-invasive bladder cancer (NMIBC) and 76 patients with muscle-invasive bladder cancer (MIBC) had transurethral resection of a bladder tumour without cystectomy, and 610 patients with NMIBC or MIBC underwent cystectomy. Most patients had a solitary lesion (56.3%) without basement membrane invasion (71.7% of Ta and/or Tis). Half of the patients with cystectomy were stage ≤T2 and 60% had non-continent diversion. Surgery included local (n=298) or super-extended lymph node dissections (n=11) and prostate removal (n=492). Among women, 16.5% underwent cystectomy and 81.4% anterior pelvectomy.Future plansCOBLAnCE will be used for long-term studies of bladder cancer with focus on clinicopathological factors and molecular markers. It will lead to a much-needed improvement in the understanding of the disease. The cohort provides valuable real-world data, enabling researchers to study various research questions, assess routine medical practices and guide medical decision-making.

Chronic inflammation may play a role in prostate cancer carcinogenesis. In that context, our objective was to investigate the role of nonsteroidal anti‐inflammatory drugs (NSAIDs) in prostate cancer risk based on the EPICAP data. EPICAP is a population‐based case–control study carried out in 2012–2013 (département of Hérault, France) that enrolled 819 men aged less than 75 years old newly diagnosed for prostate cancer and 879 controls frequency matched to the cases on age. Face to face interviews gathered information on several potential risk factors including NSAIDs use. Odds ratios (ORs) and their 95% confidence intervals (CIs) were calculated using unconditional logistic regression models. All‐NSAIDs use was inversely associated with prostate cancer: OR 0.77, 95% CI 0.61–0.98, especially in men using NSAIDs that preferentially inhibit COX‐2 activity (OR 0.48, 95% CI 0.28–0.79). Nonaspirin NSAIDs users had a decreased risk of prostate cancer (OR 0.72, 95% CI 0.53–0.99), particularly among men with an aggressive prostate cancer (OR 0.49, 95% CI 0.27–0.89) and in men with a personal history of prostatitis (OR 0.21, 95% CI 0.07–0.59). Our results are in favor of a decreased risk of prostate cancer in men using NSAIDs, particularly for men using preferential anti‐COX‐2 activity. The protective effect of NSAIDs seems to be more pronounced in aggressive prostate cancer and in men with a personal history of prostatitis, but this needs further investigations to be confirmed. Our results showed a decreased risk of prostate cancer in men using NSAIDs, especially with frequent, current, and chronic use. This effect is particularly observed in men using nonaspirin NSAIDs, and especially with preferential anti‐COX‐2 activity. Protective effect of NSAIDs seemed to be more pronounced in aggressive prostate cancer and in situation of chronic inflammation mediated by a personal history of prostatitis.

BackgroundBladder cancer detection and follow-up is based on cystoscopy and/or cytology, but it remains imperfect and invasive. Current research focuses on diagnostic biomarkers that could improve bladder cancer detection and follow-up by discriminating patients at risk of aggressive cancer who need confirmatory TURBT (Transurethral Resection of Bladder Tumour) from patients at no risk of aggressive cancer who could be spared from useless explorations.ObjectiveTo perform a systematic review of data on the clinical validity and clinical utility of eleven urinary biomarkers (VisioCyt®, Xpert®Bladder, BTA stat®, BTA TRAK™, NMP22 BC®, NMP22® BladderChek® Test, ImmunoCyt™/uCyt1+™, UroVysion Bladder Cancer Kit®, Cxbladder, ADXBLADDER, Urodiag®) for bladder cancer diagnosis and for non-muscle invasive bladder cancer (NMIBC) follow-up.MethodsAll available studies on the 11 biomarkers published between May 2010 and March 2021 and present in MEDLINE® were reviewed. The main endpoints were clinical performance for bladder cancer detection, recurrence or progression during NMIBC monitoring, and additional value compared to cytology and/or cystoscopy.ResultsMost studies on urinary biomarkers had a prospective design and high level of evidence. However, their results should be interpreted with caution given the heterogeneity among studies. Most of the biomarkers under study displayed higher detection sensitivity compared with cytology, but lower specificity. Some biomarkers may have clinical utility for NMIBC surveillance in patients with negative or equivocal cystoscopy or negative or atypical urinary cytology findings, and also for recurrence prediction.ConclusionUrinary biomarkers might have a complementary place in bladder cancer diagnosis and NMIBC surveillance. However, their clinical benefit remains to be confirmed.

Background Prostate cancer patients are known to suffer from poor sexual and urinary long-term side-effects following treatment, potentially impacting quality of life. The purpose of our study was to compare health-related quality of life at 3 years between prostate cancer patients and healthy controls according to key life-style characteristics. Secondary objectives were to compare urological dysfunction, sexual function, anxiety and depression. Methods Multicentric, case-control, observational prospective, open, follow-up study including 819 prostate cancer patients < 75 years old from the EPICAP cohort, newly diagnosed from 1 December 2011 to 31 March 2014 and 879 healthy controls. Participants were excluded if they experienced a relapse. Controls from the same geographical region were age-matched and were excluded if they were diagnosed with prostate cancer. Patients received one of the following treatments: active surveillance (AS), radical prostatectomy (RP), external beam radiotherapy (EBRT), High-intensity Focused Ultrasound (HIFU), chemotherapy (CT), or androgen deprivation therapy (ADT) as appropriate. The primary outcome was the quality of life as evaluated by the QLQ-C30 questionnaire. Scores were analyzed by multivariate analysis to adjust for predefined socio-demographic confounding effects. Results In total, 564 participants were included (mean age 67.9 years): 376 patients and 188 controls. Treatment breakdown was: 258 underwent RP, 90 received EBRT, 52 brachytherapy or HIFU, 15 CT, 26 ADT and 61 AS. There was no difference in median global quality of life between patients and controls (94.87 vs 94.15, p  = 0.71). Multivariate analysis showed poorer social functioning in patients (24.3% vs. 16.3%, p  = 0.0209), more dyspnea (22% vs. 12.4%, p  = 0.0078), and yet less current pain (23% vs 33%, p  = 0.0151). Conclusions Global health status score at 3 years after diagnosis was similar between patients and controls, though patients showed a significantly worse social functioning. Prostate cancer diagnosis per se does not seem to impact the quality of life of patients < 75 years at diagnosis. However, the therapeutic option that will be chosen following diagnosis should be carefully discussed with the medical staff in terms of benefit-risk ratios as it could have a long-term impact on urinary or erectile dysfunction.

Introduction Through a cross-sectional survey, we tried to assess whether practices of urologists and radiation oncologists are uniform when faced with similar clinical situations. Materials and Methods A self-administered questionnaire was mailed to all French urologists and radiation oncologists. Respondents were asked about their practices through 11 case scenarios. The scenarios cover most of localized prostate cancer situations and were gradually organized depending on prostate cancer progression risk and the age of the patient. The eight first scenarios address the situation of treatment-naive patients, and the last cases were about the management of patients after radical prostatectomy. Physicians were asked to choose a treatment modality for each case. The responses were first stratified according to the intention to treat: either curative-intent treatment or palliative. The curative-treatment modality chosen were afterward assessed. The responses to clinical scenarios were compared between the two specialties. Results Concerning the intention to treat, practice patterns were overall consistent except in one case. Indeed, a higher rate of radiation oncologists prefer curative-intent treatment for intermediate-risk prostate cancer in aged patients: 57.4 versus 14.6 % ( p  < 0.001). Each medical specialist prefers the treatment that he himself delivers ( p  < 0.005). For intermediate-risk prostate cancer in 65-year-old patient: 96.5 % of urologists chose radical prostatectomy versus 37.7 % of radiation oncologists ( p  < 0.001). Fewer urologists (almost 14 %) compared to radiation oncologists (47.5 %) would prescribe adjuvant treatment after radical prostatectomy for T3a R0 prostate cancer with post-operative PSA undetectable ( p  < 0.001). Conclusion Significant differences were found in therapeutic approach between the two main specialties that deal with localized prostate cancer.
