[Early detection of prostate cancer: Towards a new paradigm?] / Détection précoce du cancer de la prostate : vers un nouveau paradigme ?

Prostate cancer (PCa) is a public health issue. The diagnostic strategy for PCa is well codified and assessed by digital rectal examination, PSA testing and multiparametric MRI, which may or may not lead to prostate biopsies. The formal benefit of organized PCa screening, studied more than 10 years ago at an international scale and for all incomers, is not demonstrated. However, diagnostic and therapeutic modalities have evolved since the pivotal studies. The contribution of MRI and targeted biopsies, the widespread use of active surveillance for unsignificant PCa, the improvement of surgical techniques and radiotherapy… have allowed a better selection of patients and strengthened the interest for an individualized approach, reducing the risk of overtreatment. Aiming to enhance coverage and access to screening for the population, the European Commission recently promoted the evaluation of an organized PCa screening strategy, including MRI. The lack of screening programs has become detrimental to the population and must shift towards an early detection policy adapted to the risk of each individual.

Effectiveness of electronic patient reporting outcomes, by a digital telemonitoring platform, for prostate cancer care: the Protecty study.

Research aim and purpose: The benefits of Electronic Patient -Reported Outcomes (e-PRO) for telemonitoring are well established, allowing early detection of illnesses and continuous monitoring of patients. The primary objective of the PROTECTY study was to assess the compliance with patient use of the telemonitoring platform Cureety. An exploratory objective was to assess if the first-month health status is a prognostic factor of progression free-survival (PFS) and overall survival (OS) for prostate cancer patient. Methods: This prospective study was conducted at the Military Hospital Bégin on prostate cancer patients. Patients were allowed to respond to a symptomatology questionnaire based on CTCAE v.5.0, personalized to their pathology and treatment. An algorithm evaluates the health status of the patient based on the reported adverse events, with a classification into 2 different states: Good Health Status (GHS) and Poor Health status (PHS). Results: Sixty-one patients were enrolled between July 1st, 2020 and September 30th, 2021. The median age was 74.0 (range 58.0-94.0). 78% presented a metastatic stage, and the most represented cancer was mHSPC. Overall, 2,457 questionnaires were completed by the patients, 4.0% resulted in a health classification in to monitor or critical state. 87% of patients were classified in the GHS group. The compliance was 72% in the overall population during the first month, 71% in GHS group and 75% in PHS group. The median follow-up was 8 months. PFS at 6 months was 84% in GHS group vs. 57% in PHS group, p = 0.19. OS at 6 months was 98% in GHS group vs. 83% in PHS group, p = 0.31. Conclusions: Our study showed that compliance was satisfactory. The feasibility of remote monitoring for prostate cancer patients means that they should benefit from its implementation. Our study is also the first to assess the correlation between treatment tolerance and survival. The initial results suggest that e-PRO assessment could help identify in the early stages the patients that require further health assessment and potential therapeutic changes. While further follow-up of more patients will be required, our study highlights the importance of e-PRO in cancer patient care.

French AFU Cancer Committee Guidelines - Update 2022-2024: prostate cancer - Diagnosis and management of localised disease.

OBJECTIVE: The objective of the French Urology Association Cancer Committee is to propose an update of the recommendations for the diagnosis and management of prostate cancer (PC). METHODS: A systematic review of the literature from 2020 to 2022 was conducted by the CCAFU on the diagnosis and therapeutic management of localised PC, while evaluating the references and their levels of evidence. RESULTS: The recommendations specify the genetics, epidemiology and means of diagnosing prostate cancer, as well as the notions of screening and early detection. MRI, the gold standard imaging examination for localised cancer, is recommended before prostate biopsies are performed. The transperineal approach reduces the risks of infection. The therapeutic methods are described and recommended according to the clinical context. Active surveillance is the gold standard of treatment for tumours with a low risk for progression. Early salvage radiotherapy is recommended in case of biochemical recurrence after radical prostatectomy. Imaging, particularly molecular imaging, helps to guide the decision-making in the event of biochemical recurrence after local treatment, but should not delay early salvage radiotherapy in the event of biological recurrence after radical prostatectomy. CONCLUSION: This update of the French recommendations should help to improve the management of patients with PC.

French AFU Cancer Committee Guidelines - Update 2022-2024: prostate cancer - Management of metastatic disease and castration resistance.

OBJECTIVE: The objective of the French Urology Association Cancer Committee is to propose an update of the recommendations for the management of prostate cancer. METHODS: A systematic review of the literature from 2020 to 2022 was conducted by the CCAFU on the elements of therapeutic management of metastatic and castration-resistant prostate cancer (PC), while evaluating the references and their levels of evidence. RESULTS: Androgen deprivation therapy (ADT) remains the standard treatment for metastatic prostate cancer. ADT intensification is now a standard of care in the management of metastatic prostate cancer. This intensification is discussed in relation to the patient and the characteristics of the disease. For all metastatic hormone-sensitive PC (synchronous and metachronous), the overall survival benefit associated with good tolerability makes the combination of ADT and novel hormonal agents (NHA) a standard. For patients with high-volume/high-risk de novo metastatic disease, treatment with docetaxel in addition to ADT + NHA can be discussed for eligible patients. In patients with castration-resistant prostate cancer (CRPC), the contribution of new therapies that have become available in recent years, as well as the advent of precision medicine, help to improve the control of tumour progression and survival, and highlight the value of testing for alterations in DNA repair genes within the tumour tissue or constitutionally. CONCLUSION: This update of the French recommendations should help to improve the management of patients with prostate cancer.

[Recent advances in the management of localized high-risk prostate cancer: An update by the Prostate Cancer Committee of the French Association of Urology]. / Avancées récentes dans la prise en charge du cancer de la prostate localisé à haut risque : mise au point par le Comité Prostate de l'Association française d'urologie.

INTRODUCTION: The risk of recurrence is increased in localized high-risk prostate cancer (PCa). The implementation of an appropriate diagnostic and therapeutic strategy is essential. The objective of this update by the Prostate Committee of the French Association of Urology was to report the most recent data in the management of localized high-risk PCa. MATERIAL AND METHODS: This update is based on the data available in the literature on localized high-risk PCa. A PubMed search and narrative review of the recent data were performed in March 2022. RESULTS: Compared with conventional imaging, PET-PSMA is more effective for the diagnosis of lymph nodes and distant metastases. Two recent randomized clinical trials have failed to prove the oncologic benefit of extended pelvic lymph node dissection during radical prostatectomy (RP). Postoperatively, early salvage radiotherapy is the standard of care, with adjuvant radiotherapy becoming an option in case of unfavorable pathological criteria (ISUP 4-5, pT3±positive margins) in young patients. Although promising, perioperative systemic therapies (chemotherapy, second-generation hormonotherapy) cannot be recommended at this time when the patient is treated by RP. Regarding radiotherapy, prophylactic lymph node irradiation during prostatic irradiation was associated with improved biochemical and metastasis-free survival in a recent randomized trial but it is still controversial. Since the publication of the results of the STAMPEDE trial, the addition of abiraterone acetate to radiation-hormone therapy should be considered the new standard of care for patients with localized (very) high-risk PCa, according to the inclusion criteria of the study. CONCLUSION: The most recent data of the literature regarding the management of high-risk localized PCa redefine the diagnostic performance of molecular imaging, the timing of postoperative radiotherapy, the oncologic benefit of pelvic lymph node treatment, and the intensification of systemic therapies.

[DNA repair gene alterations testing in prostate cancer : A practical update by the prostate cancer committee of the french association of urology]. / Recherche d'altérations des gènes de réparation de l'ADN dans le cancer de la prostate : mise au point pratique du Comité de cancérologie de l'association française d'urologie.

INTRODUCTION: Current therapeutic developments in prostate cancer (PCa) tend to increasingly personalize the treatment strategy, in particular as a function of tumor genomics. Recently, poly ADP-ribose polymerase (PARPi) inhibitors have shown their efficacy at the stage of castration resistance, in case of alteration of DNA repair genes in tumor tissue. MATERIAL AND METHODS: A narrative review was carried out on recent data in the literature since 2000. A consensus among the members of the Committee was obtained in order to synthesize the current data, with a particular focus on the practical considerations regarding indications and developments of molecular testing circuits concerning DNA repair genes, for theranostics purpose. RESULTS: The establishment of an efficient molecular testing network is based on the multidisciplinary organization of the various actors and the coordination of all material resources. Its goal is the routine search for somatic mutations (in tumor tissue) of BRCA1/2 genes in patients who may benefit from PARPi. The current indications are for BRCA1 or 2 mutated castration-resistant metastatic PCa after next-generation hormone therapy failure. The demand for molecular testing must be decided in the tumor board, giving priority to archived tissue less than 10 years old. In case of unsuccess, biopsies of the primary or metastases, or even analysis of circulating tumor DNA, may be necessary. Any demand for a genetic test on tumor tissue must be accompanied by detailed information for the patient on the possible familial consequences, in case of associated germline mutation. CONCLUSION: This article aims to guide the practical implementation of molecular testing circuits for DNA repair genes alterations, in order to guide the therapeutic management of patients with advanced PCa.

Narrative review of PET/CT performances at biochemical recurrence in prostate cancer after radical prostatectomy and impact on patient disease management: Revue narrative à propos des performances de la TEP/TDM en cas de récidive biochimique après prostatectomie radicale dans le cancer de la prostate et impact sur la prise en charge des patients.

Patients treated by radical prostatectomy (RP) for localized prostate cancer (PCa) may experience biochemical recurrence (BCR) in approximately 30% of cases. Recently, advances in imaging modalities and in particular Positron-Emission Tomography with computed tomography (PET/CT) imaging allow for better detection and characterization of lesions outside the prostatic bed at recurrence. Thus, treatment at BCR can be significantly improved by a tailored strategy based on new generation imaging. A more precise and accurate staging of the disease at recurrence paves the way to more appropriate treatment, potentially translating into better survival outcomes of these patients. This review therefore highlights the interest of PET/CT at the time of BCR, its superiority over standard imaging in terms of staging, and its impact on guiding the different therapeutic possibilities depending on the site, number, and volumes of recurrence. Indeed, we will discuss below about different strategies and their indications: salvage radiotherapy of the prostate bed, systemic therapies, stereotactic body radiotherapy and others therapeutical strategies. The various innovative approaches based on PET/CT implementation are partly underway within protocol trials to prove their benefits on clinically meaningful endpoints. © 2022 Elsevier Masson SAS.

How PET-CT is Changing the Management of Non-metastatic Castration-resistant Prostate Cancer?: Comment la TEP-TDM Peut Modifier la Prise en Charge du Cancer de la Prostate Non Métastatique Résistant à la Castration ?

INTRODUCTION: The aim of this narrative review conducted by the Prostate Cancer Committee of the French Association of Urology (CC-AFU) was to provide an update on the current evidence for the impact of PET/CT in the management of men with non-metastatic castration-resistant prostate cancer (nmCRPC). MATERIAL AND METHODS: This review is based on data available in the literature on PET/CT imaging for staging nmCRPC patients. A PubMed search and narrative review of the data were performed in March 2022. Only articles in French or English were considered. RESULTS: Current guidelines recommend bone scan and CT scan as standard imaging modalities for staging and follow-up of patients with nmCRPC. Nearly one-third of asymptomatic patients with presumed nmCRPC ultimately have metastatic disease on conventional imaging. Increasing reports have shown that conventional imaging has limited accuracy in detecting metastatic disease in nmCRPC patients, leading to the development of next-generation imaging techniques. In a retrospective study, 18F-choline PET/CT detected distant metastases in 27/58 high-risk nmCRPC patients with prior negative conventional imaging. The implementation of radiolabeled ligands of the prostate-specific membrane antigen (PSMA) PET/CT in staging strategy has resulted in metastasis detection in 45% to 98% of patients with presumptive nmCRPC on conventional imaging. Such an early diagnosis of metastatic CRPC may allow patients to be referred for metastasis-directed therapies (i.e. stereotactic body radiotherapy), aimed at prolonging the efficacy of systemic therapies and improving clinical outcomes. However, current data are not strong enough to recommend this strategy, which must be properly evaluated in clinical trials. Indeed, the use of molecular imaging may lead to inappropriate undertreatment if the second-generation androgen receptor inhibitors (darolutamide, enzalutamide, apalutamide), which prolong life, are not used in the subgroup of patients with high PSA velocity (PSA doubling time <10 months). CONCLUSION: Implementation of PSMA-PET/CT in the staging strategy would result in a migration of disease stage to extra-pelvic, M1 disease in at least half of presumed nmCRPC patients. The unprecedented accuracy of PSMA-PET/CT may pave the way for a more personalized treatment strategy. However, no data yet support this strategy for all nmCRPC patients as no oncologic benefit of early detection of M1 disease or MDT has been demonstrated. © 2022 Elsevier Masson SAS.

[High-intensity focused ultrasound for locally prostate cancer: An Afro-Caribbean single-center study]. / Ultrasons focalisés de haute intensité pour le traitement du cancer localisé de la prostate : étude mono-centrique caribéenne.

INTRODUCTION: High-intensity focused ultrasound (HIFU) has proved to be effective in the treatment of localized prostate cancer. The aim of this prospective study is to assess their first oncological and functional results in an Afro-Caribbean population. METHODS: From May 2018 to January 2020, 77 patients issued from French West Indies were included. Several treatments were carried out: whole-gland treatment hemi or focal ablation; in a primary setting (group I) or a salvage therapy (group II). PSA level was assessed at 2, 6, 9 and 12 months. MpMRI and post HIFU biopsy were performed between 6 and 9 months postoperatively. Continence, urinary end erectile functions were assessed by ICS, IPSS and IIEF scores. RESULTS: Groupe I included 71.2% patients, group II, 28.8%. The median age was 75.4 years [IQR 69.6-79.4]. The median follow-up was 8.3 months [IQR 3.5-12.25]. At inclusion, PSA was 7.7ng/ml [IQR 5.5-11.2] in group I, and 5.9ng/ml [IQR 4.4-7.9] in group II. In the whole population, there was 73.5% negative biopsies; 14.7% of the biopsies were positive in treated zone and 11.8% in non-treated zone. Regarding morbidities, urinary incontinence appeared in 7.5% and erectile dysfunction rate was 13.2%. CONCLUSION: Our study reveals the first experience of HIFU by Focal One® device in an Afro-Caribbean population. It seems to be a safe and reproducible treatment with acceptable oncological results and low genitourinary morbidity. Long term follow-up and a higher number of patients are necessary to validate these results.

[French ccAFU guidelines - update 2020-2022: prostate cancer]. / Recommandations françaises du Comité de cancérologie de l'AFU ­ actualisation 2020­2022 : cancer de la prostate.

OBJECTIVE: - The purpose of the guidelines national committee ccAFU was to propose updated french guidelines for prostate cancer. METHODS: - A Medline search was achieved between 2018 and 2020, as regards diagnosis, options of treatment and follow-up of prostate cancer (PCA), and to evaluate the different references specifying their levels of evidence. RESULTS: - The guidelines outline the genetics, epidemiology and diagnosis of prostate cancer, as well as the concepts of screening and early detection. MRI, the gold standard imaging test for localized cancer, is indicated before prostate biopsies are performed. The therapeutic methods are detailed and indicated according to the clinical situation. Active surveillance is a reference therapeutic option for low-risk tumours with a low evolutionary risk. Early salvage radiotherapy is indicated in case of biological recurrence after radical prostatectomy. Androgen deprivation therapy (ADT) remains the backbone therapy in the metastatic stage. Docetaxel in combination with ADT improves overall first-line survival in synchronous metastatic prostate cancer. In this situation, the combination of ADT with abiraterone is also a standard of care regardless of tumor volume. Recent data indicate that ADT should be indicated with a new generation of hormone therapy (Apalutamide or Enzalutamide) in metastatic synchronous or metachronous patients, regardless of tumour volume. Local treatment of prostate cancer with radiotherapy improves survival in synchronous oligometastatic patients. Targeted treatment of metastases is being evaluated. In patients with castration-resistant prostate cancer (CRPC), new therapies that have emerged in recent years help to better control tumor progression and improve survival. CONCLUSION: - These updated french guidelines will contribute to increase the level of urological care for the diagnosis and treatment for prostate cancer.

[French CCAFU guidelines on prostate cancer: hormone-sensitive metastatic prostate cancer-update 2020]. / Recommandations françaises du comité de cancérologie de l'AFU pour le cancer de la prostate : cancer de prostate métastatique hormono-sensible­actualisation 2020.

OBJECTIVE: The aim of the Cancerology Committee of the French Association of urology (CCAFU) is to propose an update of the guidelines in the management of hormone-sensitive metastatic prostate cancer. METHODS: A systematic review (Medline) of the literature from 2018 to 2020 was conducted by the CCAFU Findings. Several patterns can be defined at this stage depending on prognostic, metastatic volume, and whether metastases are synchronous or metachronous. Androgenic deprivation therapy (ADT) remains the mainstay of treatment at the metastatic stage. Docetaxel in combination with ADT improves overall survival in synchronous metastatic prostate cancer. In this situation, the combination of ADT with abiraterone is also a standard of care regardless of tumor volume. Recent data have led to the recommendation that ADT should be used in conjunction with a new generation hormone therapy (Apalutamide or Enzalutamide) in metastatic synchronous or metachronous patients, regardless of tumour volume. Local treatment of prostate cancer with radiotherapy improves survival in synchronous oligometastatic patients. Metastases-directed therapy is being evaluated. CONCLUSION: This update of the French recommendations should help improve the management of patients with prostate cancer.

Active surveillance in prostate cancer is possible for Afro-Caribbean population: Comparison of oncological outcomes with a Caucasian cohort.

BACKGROUND: Prostate cancer is supposedly more aggressive among Afro-Caribbean men. There is a lack of data in this population for active surveillance. Published series are retrospective or have small samples and results are discordant. The objective was to determinate whether actual active surveillance modalities can be applied for Afro-Caribbean men by comparing their oncological outcomes with Caucasian men. METHODS: A total of 449 consecutive patients who underwent active surveillance for favorable-risk prostate cancer in two French University-Medical-Centers between 2005 and 2018: 261 in Guadeloupe, French West Indies, and 188 in Bordeaux, metropolitan France. Median follow-up was 56 months, (95% CI [32-81]) and 52 months (95% CI [30-75]), respectively (P=0.07). Curative treatment was given in case of histological, biological, or imaging progression, or upon patient demand. Primary endpoints were treatment-free, overall and specific survival. Secondary outcomes were reasons of discontinuating active surveillance, histological poor prognosis factors after prostatectomy, CAPRA-S score, biochemical-recurrence-free after treatment and metastasis-free survival. Kaplan-Meier method was used. RESULTS: Median treatment free survival was 58.4 months (CI 95% [48.6-83.1]) for ACM and not reached at 120 months for CM (P=0.002). Overall survival (P=0.53), and specific survival (P=0.21) were similar in the two groups. CM were likely to have poor prognosis factor on prostatecomy piece (57 vs 30%, P=0.01). No difference for repartition of the CAPRA-S score (P=0.86), biochemical-recurrence-free (P=0.92) and metastasis-free (P=0.44) survival. CONCLUSIONS: Oncological outcomes for active surveillance of Afro-Caribbean and Caucasian men were similar in terms of mortality, recurrence and metastasis in our bicentric study, showing usability of current criteria for Afro-Caribbean. The higher rate of disease progression in the Afro-Caribbean population requires close monitoring. LEVEL OF EVIDENCE: 3.

[Pelvimetrics measures as predictives factors of positives surgical margins after robot-assisted laparoscopic prostatectomy]. / Mesures pelvimétriques prédictives de marges chirurgicales au décours d'une prostatectomie totale robot-assitée pour cancer prostatique.

INTRODUCTION: Anthropometric data report that pelvic bone of African subjects are narrower and the pelvic cavity is deeper. The aim of the study was to evaluate the influence of pelvic dimensions (PD) on Positive surgical margins (PSM) rate in Afro-Caribbean population after robot-assisted laparoscopic prostatectomy (RALP). PATIENTS AND METHODS: Preoperative pelvic MRI of all patients who have had RALP at the University Hospital Center of Guadeloupe between January 2013 and December 2015 was retrospectively analyzed. PD, including the Height of the upper edge of the prostate (HP), the Apical Depth (AD) and Ischial Spines Distance (ISD), and indexes (prostate volumetric index [ISD/VP], apical depth index [ISD/AD] and prostate depth index [ISD/(AD/HP)]) were compared according to the presence or absence of PSM with uni and multivariate analysis. RESULTS: One hundred and seventy-eight patients were included in the study, of whom 60 (33.7%) presented PSM. In univariate analysis, significant differences between the presence or absence of PSM were observed on the AD (30.3±8.7mm versus 24.8±8.0mm, P<0.001), the HP (9.5±8.5mm versus 16.8±11.9mm, P<0.001) and the ISD (89.6±8.8mm versus 96.1±8.4mm) as well as the indexes of apical depth and prostatic depth. In multivariate logistic regression, the ISD (P<0.001) and HP (P=0.02) were associated with increased likelihood of PSM, but not AD or indexes. CONCLUSION: This study suggests that interspinous distance is the best predictor of PSM during RALP in Afro-Caribbean patients. This measure may be useful to define the therapeutic pattern of patients with prostate cancer. A prospective study with a larger population, comparing RALP in Afro-Caribbean and in caucasians patients, would be needed.

Comprehensive molecular classification of localized prostate adenocarcinoma reveals a tumour subtype predictive of non-aggressive disease.

Background: Management of localized prostate cancer (PCa) is a major clinical challenge since most of these cancers would not evolve but a majority of patients will still undergo a life-changing radical surgery. Molecular studies have shown that PCa can be classified according to their genomic alterations but none of the published PCa molecular classifications could identify a subtype corresponding to non-evolutive tumours. Materials and methods: Multi-omics molecular profiling was carried out on post-radical prostatectomy material from a cohort of 130 patients with localized PCa. We used unsupervised classification techniques to build a comprehensive classification of prostate tumours based on three molecular levels: DNA copy number, DNA methylation, and mRNA expression. Merged data from our cohort and The Cancer Genome Atlas cohort were used to characterize the resulting tumour subtypes. We measured subtype-associated risks of biochemical relapse using Cox regression models and survival data from five cohorts including the two aforementioned. Results: We describe three PCa molecular subtypes associated with specific molecular characteristics and different clinical outcomes. Particularly, one subtype was strongly associated with the absence of biochemical recurrence. We validated this finding on 746 samples from 5 distinct cohorts (P = 3.41 × 10-8, N = 746 tumour samples), and showed that our subtyping approach outperformed the most popular prognostic molecular signatures to accurately identify a subset of patients with a non-evolutive disease. We provide a set of 36 transcriptomic biomarkers to robustly identify this subtype of non-evolutive cases whose prevalence was estimated to 22% of all localized PCa tumours. Conclusion: At least 20% of patients with localized PCa can be accurately predicted to have a non-evolutive disease on the basis of their molecular subtype. Those patients should not undergo immediate surgery and rather be placed under active surveillance.

Predictors of biochemical recurrence after radical prostatectomy in an Afro-Caribbean population in Guadeloupe (French West Indies).

PURPOSE: Few studies have investigated predictive risk factors of biochemical recurrence (BCR) after radical prostatectomy (RP) in other than Caucasian and Asian populations. We aimed to identify pre- and post-operative predictors of BCR after RP in an Afro-Caribbean population in Guadeloupe (French West Indies). PATIENTS AND METHODS: The study included 964 patients who underwent RP for clinically localized prostate cancer between April 1, 2000 and December 31, 2010 in the University Hospital of Guadeloupe. The hazard ratio (HR) and corresponding 95% confidence interval (CI) for single variable associations with BCR were calculated using the Cox proportional hazards regression. Multiple variable analyses for association with BCR were performed, including all variables that reached statistical significance (P value<0.05) in univariate analysis. A backward selection model was then applied with a P value ≥0.1 for retention in the final model. Sensitivity analysis was performed and restricted to patients with known values for all variables (complete case analysis). RESULTS: With a median follow-up of 4.8 years, the BCR rate was 26.7%. In multivariable analysis, predictors of BCR before surgery were diabetes mellitus type 2 (DT2) (HR: 1.37, 95% CI: 1.02-1.85; P=0.038), pre-operative PSA>7.5ng/ml (1.49, 1.15-1.92; P=0.002), clinical stage T2 (1.55, 1.21-1.98; P=0.0006), Gleason score>7 or 4+3 (2.12, 1.54-2.91; P<0.0001), and percentage of length of biopsy positive scores (1.66, 1.24-2.20; P=0.0006). Predictors of BCR after surgery were DT2 (HR: 1.37, 95% CI: 1.01-1.85; P=0.045), pre-operative PSA>7.5ng/ml (1.37, 1.06-1.79; P=0.018), pathological Gleason score>7 or 4+3 (2.36, 1.74-3.19; P<0.0001), pathological stage pT3b (1.68, 1.15-2.45; P=0.007), positive surgical margins (1.72, 1.32-2.45; P=0.0001), and perioperative blood loss>2000ml (3.74, 1.37-10.2; P=0.01). The results were virtually the same by sensitivity analysis (complete cases), except for DT2, which was associated with BCR with borderline statistical significance in the pre-operative model and not retained in the post-operative model. CONCLUSIONS: Afro-Caribbean populations in French West Indies share the same major clinical and pathological risk factors of BCR after RP identified in other ethnic groups. Perioperative blood loss appears to be an additional and independent predictive factor of BCR. LEVEL OF PROOF: 4.

[French ccAFU guidelines - Update 2018-2020: Prostate cancer]. / Recommandations françaises du Comité de Cancérologie de l'AFU ­ Actualisation 2018­2020 : cancer de la prostate.

OBJECTIVE: The purpose of the guidelines national committee ccAFU was to propose updated French guidelines for prostate cancer. METHODS: A Medline search was achieved between 2016 and 2018, as regards diagnosis, options of treatment and follow-up of prostate cancer, and to evaluate the different references specifying their levels of evidence. RESULTS: Epidemiology, classification, staging systems, diagnostic evaluation of prostate cancer are reported. Disease management options are detailed. Recommandations are reported according to the different clinical situations. Active surveillance is a major option in low risk PCa. Radical prostatectomy remains a standard of care of localized PCa. The three-dimensional conformal radiotherapy is the technical standard. A dose of≥76Gy is recommended. Moderate hypofractionation provides short-term biochemical control comparable to conventional fractionation. In case of intermediate risk PCa, radiotherapy can be combined with short-term androgen deprivation therapy (ADT). In case of high-risk disease, long-term ADT remains the standard of care. ADT is the backbone therapy of metastatic disease. In men with metastases at first presentation, upfront chemotherapy combined with ADT should be considered as a standard. In this situation, the combination of ADT and abiraterone acetate also becomes a new standard. In case of metastatic castration-resistant PCa (mCRPC), new hormonal treatments and chemotherapy provide a better control of tumor progression and increase survival. CONCLUSION: These updated French guidelines will contribute to increase the level of urological care for the diagnosis and treatment for prostate cancer.

[Epidemiology of urolithiasis in French West Indies: A retrospective study]. / Épidémiologie de la lithiase urinaire aux Antilles françaises : étude rétrospective monocentrique.

INTRODUCTION: The incidence of urolithiasis is increasing with dietary changes especially in developed countries. Guadeloupe is a French department overseas where western diet meets traditional local food. The objective was to describe and analyze the epidemiology of urolithiasis in Guadeloupe. MATERIAL AND METHODS: We conducted a retrospective single-center study throughout the year 2015 on patients hospitalized for urolithiasis at University Hospital of Pointe-à-Pitre. Data of the patients, treatments performed and the types of stones were recorded. According to their mineral content, groups were composed. RESULTS: In total, 165 patients were included. The sex ratio was 1.61. The median body mass index (BMI) was 26.5kg/m2. The most common stone was oxalocalcic (64.7%). Mixed stones (24.7%) were in second place. There were only 3.5% of uric acid urolithiasis. Calcium oxalate stones were predominantly monohydrate. The oxalocalcic stones were significantly more frequent in men (80% versus 47.5%, P=0.01) and in the age group over 50 years old (72.2% versus 51.6%, P=0.04). There was no association between the type of stone and the BMI. CONCLUSION: Epidemiology of urolithiasis in our French Caribbean island is, therefore, similar to continental France. However, our population is distinguished by the proportion of women affected and by the different proportions among each type of stone. Other studies on larger samples are needed to study these specificities. LEVEL OF EVIDENCE: 4.

[Temocillin and urinary tract infections]. / Place de la témocilline dans le traitement des infections urinaires.

INTRODUCTION: Temocillin is an alternative to treat urinary tract infections with bacteria producing extended spectrum beta-lactamase (ESBL). The objective is to evaluate the use of temocillin in urinary tract infections. MATERIALS AND METHODS: A systematic review of literature was carried out according to PRISMA criteria. All national and international recommendations have been reviewed regarding the indication of the use of temocillin in urology. Data collection on the use of temocillin in urinary tract infection has been performed from the Cochrane, LILACS and the Medline database. The following keywords were used: temocillin, extended spectrum beta-lactamase, urinary tract infections, urine, prostate, epididymis, testis, diffusion, pharmacokinetics, pharmacodynamics. The selection was based on the methodology, language of publication (English/French), relevance to the topic and date of publication of the articles collected. The endpoint was to provide exhaustive scientific information allowing urologists to use this antibiotic in febrile urinary infections. RESULTS: Bacteria producing ESBL has a relatively high susceptible to temocillin, ranging from 61 % to 90 %. These rates would allow its use in probabilistic. The dosage recommended is currently, in the normo-renal patient, 4g per day by intermittent infusion or continuously after a loading dose of 2g. Some studies argue, particularly in case of difficult clinical situations or obese patients, for administration of high doses (6g/24h) rather continuous infusion. There is no evident relationship between high doses and side effects. With an excellent urinary and prostatic diffusion, temocilllin might be recommend for the treatment of ESBL prostatitis. CONCLUSION: Temocillin is known to have good urinary and prostatic diffusion. According to our results, this antibiotics is now a reliable alternative for the treatment of documented ESBL urinary tract infections. LEVEL OF EVIDENCE: 4.
