A collaborative review of the microsatellite instability/deficient mismatch repair phenotype in patients with upper tract urothelial carcinoma.

OBJECTIVE: To perform a collaborative review of the literature exploring the microsatellite instability/deficient mismatch repair (MSI/dMMR) phenotype in patients with upper tract urothelial carcinoma (UTUC). METHOD: A collaborative review of the literature available on Medline was conducted by the Cancer Committee of the French Association of Urology to report studies describing the genetic mechanisms, investigation, prevalence and impact of the MSI/dMMR phenotype in UTUC patients. RESULTS: The predominant genetic mechanism leading to the MSI/dMMR phenotype in UTUC patients is related to the constitutional mutation of one allele of the MMR genes MLH1, MSH2, MSH6 and PMS2 within Lynch syndrome. Indications for its investigation currently remain limited to patients with a clinical suspicion for sporadic UTUC to refer only those with a positive testing for germline DNA sequencing to screen for this syndrome. With regard to technical aspects, despite the interest of MSIsensor, only PCR and immunohistochemistry are routinely used to somatically investigate the MSI and dMMR phenotypes, respectively. The prevalence of the MSI/dMMR phenotype in UTUC patients ranges from 1.7% to 57%, depending on the study population, investigation method and definition of a positive test. Younger age and a more balanced male to female ratio at initial diagnosis are the main specific clinical characteristics of UTUC patients with an MSI/dMMR phenotype. Despite the conflicting results available in the literature, these patients may have a better prognosis, potentially related to more favourable pathological features. Finally, they may also have lower sensitivity to chemotherapy but greater sensitivity to immunotherapy. CONCLUSION: Our collaborative review summarises the available data from published studies exploring the MSI/dMMR phenotype in UTUC patients, the majority of which are limited by a low level of evidence.

A prospective descriptive 1-year study in France of all BCG therapy dispensations for non-muscle-invasive bladder cancer.

OBJECTIVES: To describe the clinico-pathological characteristics of non-muscle-invasive bladder cancer (NMIBC) treated in metropolitan France over 1 year when bacille Calmette-Guérin (BCG) was subject to a national quota, and to document, in the context of recurrent shortages of intravesical BCG for NMIBC, the real-life indications for adjuvant treatment. MATERIALS AND METHODS: Between February 2021 and February 2022, the French National Agency for the Safety of Medicines (ANSM) asked the French Association of Urology to propose a science-based quota solution for BCG using a clinical score. The ANSM then asked the distributor of the drug, MEDAC, to collect the scores for all patients for whom BCG was requested by healthcare institutions and to prioritize the requests for patients with the highest scores. Tumour stage, grade, size, number, time to recurrence, carcinoma in situ, age, accessibility of alternative treatments (total cystectomy, radio-chemotherapy, thermo-chemotherapy) and BCG treatment progress (initiation or maintenance) were documented for each intravesical BCG prescription. A descriptive analysis of the data collected during the quota year was performed. RESULTS: During the 1-year quota, 25 878 requests for BCG were made for 19 024 patients, 60.5% of whom were aged ≥70 years. Requests for induction and maintenance treatment accounted for 12 704 (49.1%) and 13 174 prescriptions (50.9%), respectively. NMIBC treated with BCG maintenance therapy was more frequently high-risk NMIBC (91.7% vs 90.2%; P < 0.0001) than NMIBC for which induction therapy was requested. The number of cases of NMIBC leading to BCG adjuvant treatment was estimated at 12 704 cases/66 062 188 inhabitants over 1 year in metropolitan France. CONCLUSIONS: Our data suggest that the incidence of NMIBC at high risk of recurrence and progression is underestimated in reference epidemiological studies. These results should help to better define future care needs.

Prognostic value of programmed death ligand-1 and programmed death-1 expression in patients with upper tract urothelial carcinoma.

OBJECTIVE: To evaluate the prognostic value of programmed death ligand-1 (PD-L1) and programmed death-1 (PD-1) expression in patients with upper tract urothelial carcinoma (UTUC). PATIENTS AND METHODS: A retrospective multicentre study was conducted in 283 patients with UTUC treated with radical nephroureterectomy (RNU) between 2000 and 2015 at 10 French hospitals. Immunohistochemistry analyses were performed using 2 mm-core tissue microarrays with NAT105® and 28.8® antibodies at a 5% cut-off for positivity on tumour cells and tumour-infiltrating lymphocytes to evaluate PD-L1 and PD-1 expression, respectively. Multivariable Cox regression models were used to determine the independent predictors of recurrence-free (RFS), cancer-specific (CSS) and overall survival (OS). RESULTS: Overall, 63 (22.3%) and 220 (77.7%) patients with UTUC had PD-L1-positive and -negative disease, respectively, while 91 (32.2%) and 192 (67.8%) had PD-1-positive and -negative disease, respectively. Patients who expressed PD-L1 or PD-1 were more likely to have pathological tumour stage ≥pT2 (68.3% vs 49.5%, P = 0.009; and 69.2% vs 46.4%, P < 0.001, respectively) and high-grade (90.5% vs 70.0%, P = 0.001; and 91.2% vs 66.7%, P < 0.001, respectively) disease with lymphovascular invasion (52.4% vs 17.3%, P < 0.001; and 39.6% vs 18.2%, P < 0.001, respectively) as compared to those who did not. In multivariable Cox regression analysis adjusting for each other, PD-L1 and PD-1 expression were significantly associated with decreased RFS (hazard ratio [HR] 1.83, 95% confidence interval [CI] 1.09-3.08, P = 0.023; and HR 1.59, 95% CI 1.01-2.54, P = 0.049; respectively), CSS (HR 2.73, 95% CI 1.48-5.04, P = 0.001; and HR 1.96, 95% CI 1.12-3.45, P = 0.019; respectively) and OS (HR 2.08, 95% CI 1.23-3.53, P = 0.006; and HR 1.71, 95% CI 1.05-2.78, P = 0.031; respectively). In addition, multivariable Cox regression analyses evaluating the four-tier combination of PD-L1 and PD-1 expression showed that only PD-L1/PD-1-positive patients (n = 38 [13.4%]) had significantly decreased RFS (HR 3.07, 95% CI 1.70-5.52; P < 0.001), CSS (HR 5.23, 95% CI 2.62-10.43; P < 0.001) and OS (HR 3.82, 95% CI 2.13-6.85; P < 0.001) as compared to those with PD-L1/PD-1-negative disease (n = 167 [59.0%]). CONCLUSIONS: We observed that PD-L1 and PD-1 expression were both associated with adverse pathological features that translated into an independent and cumulative adverse prognostic value in UTUC patients treated with RNU.

Which revision strategy is the best for non-mechanical failure of male artificial urinary sphincter?

PURPOSE: Persistence or recurrence of stress urinary incontinence (prSUI) after artificial urinary sphincter (AUS) implantation may be secondary to non-mechanical failure (NOMECA). It have for long been assumed to result from urethral atrophy. Its existence is now debated. As the pathophysiology of NOMECA is not elucidated, the most appropriate management remains unclear. We aimed to compare the several revision techniques for NOMECA of AUS in men. METHODS: NOMECA was defined as prSUI, with normally functioning device, no erosion, infection or fluid loss. Exclusion criteria were neurogenic SUI, revision or explantation for other causes. From 1991 to 2022, 143 AUS revisions for NOMECA, including 99 cuff DOWNSIZING, 10 cuff repositioning (RELOC), 13 TANDEM-CUFF placement, 18 cuff changing (CHANGE), three increasing balloon pressure (BALLOON-UP), were performed in 10 centers. BALLOON-UP patients weren't included in comparative analysis due to small sample size. All components could be changed during the revision. Patients were also categorized in COMPLETE-CHANGE vs. PARTIAL-CHANGE of the device. RESULTS: The three-months complete continence rate was 70.8% with a significant difference between RELOC and DOWNSIZING groups (p = 0.04). COMPLETE CHANGE was significantly associated with complete continence status at three months in multivariate analysis (83.3% vs. 63.3%, OR = 2.7; CI 95% [1.1-7.1], p = 0.03). Estimated five-year reoperation-free and explantation-free survival were respectively 63.4% and 75.9% (p = 0.16; p = 0.30). Those were significantly longer in COMPLETE-CHANGE vs PARTIAL-CHANGE (82.2% vs. 69.6%, p = 0.03); (71.2% vs. 58.2%, p = 0.047). CONCLUSIONS: AUS revision for prSUI due to NOMECA yields satisfactory outcomes regardless of the technique used. We observed better functional outcomes when repositioning the new cuff. COMPLETE-CHANGE may improve functional outcomes, explantation-free and reoperation-free survivals.

[Outpatient surgery for penile hypospadias in pediatric urology: A monocentric experience with a mean follow-up of 3 years]. / Chirurgie ambulatoire de l'hypospade pénien pédiatrique : expérience monocentrique avec un recul moyen de 3 ans.

INTRODUCTION: Hypospadias is one of the most common congenital anomalies in men. Outpatient surgery has been proposed but is not widespread. The aim of this study was to evaluate our experience of outpatient surgery for penile hypospadias repair and to specify the constraints for a result similar to a conventional inpatient procedure. PATIENTS AND METHODS: Observational, retrospective and single-center study, including all the patients operated on hypospadias for the first time by one of the 3 senior surgeons, between January 2011 and March 2018. Peno-scrotal and perineal hypospadias were excluded because systematically hospitalized. RESULTS: One hundred sixty-six patients were included. 67 patients (40,4%) were treated on an outpatient basis. The mean age at the time of procedure was 15.6 (6-51) months. Forms with curvature were almost exclusively hospitalized (1 vs. 25, P<0.001). There was no significant difference for anterior penile forms (60 vs. 81, P=0.06). Middle and posterior hypospadias were more often hospitalized, although outpatient experience exists. There were no more complications in the outpatient group. CONCLUSION: Outpatient hypospadias surgery seems to be achievable in most of the cases, provided that medical care is standardized and multidisciplinary, the staff is trained and involved and a specific organization is put in place in the department. Evaluation of the socio-family environment is therefore fundamental.

A study of the immunohistochemical profile of bladder cancer in neuro-urological patients by the French Association of Urology.

PURPOSE: To establish whether the expression of markers of cell differentiation (CK7, CK14, CK20, GATA3), apoptosis (p53), proliferation (Ki67, STAG2) and peri-tumoural lymphocytes (CD3, CD8), provides specific information about urothelial carcinogenesis in neuro-urological patients with bladder cancer (NBC). METHODS: Tissue samples from NBC were retrieved from 15 centres in France and compared to control samples from non neuro-urological patients with bladder cancer (NNBC) and from neuro-urological patients without bladder cancer (NB). The expression of CK7, CK14, CK20, GATA3, p53, Ki67, STAG2, CD3 and CD8 markers was analysed using immunohistochemistry of tissue microarray sections. RESULTS: Overall, tissue samples from 124 patients were included in the study (n = 72 NBC, n = 26 NNBC and n = 26 NB). Muscle invasive bladder cancer (MIBC) was found in 52 NBC patients (72.2%) and squamous cell differentiation in 9 (12.5%). In NBC samples, the expression of CK20 and GATA3 was significantly more frequent in NMIBC compared to MIBC (p = 0.015 and p = 0.004, respectively). CK20 and GATA3 were significantly more expressed in NBC compared to NNBC (p < 0.001 and p = 0.010, respectively). The expression of CK14, Ki67, CD3 and CD8 was significantly more frequent in NBC than in NNBC samples (p = 0.005, p < 0.001, p < 0.001 and p < 0.001, respectively). The expression of CD3 and CD8 was similar in NBC and NB samples. CONCLUSION: In NBC, markers of basal differentiation, proliferation and peri-tumoural lymphocytes were significantly more expressed compared to NNBC controls. These results suggest the aggressiveness of NBC and the role of chronic inflammation in the carcinogenesis of bladder cancer in neuro-urological patients.

Impact of COVID-19 pandemic on functional urology procedures in France: a prospective study.

PURPOSE: To evaluate the impact of COVID-19 pandemic on functional urology procedures in France. METHODS: A prospective study was conducted within 11 secondary and tertiary referral centers in France. Patients aged > 18 years who were diagnosed with a functional urology disease before the national lockdown (March 17th, 2020) and who required a surgery were included. Study period went from March 17th to September 30th 2020. The included interventions were listed according to the guidelines for functional urology enacted by the French Association of Urology and delay of reoperation was compared to the guidelines' delay. The primary outcome was the number of procedures left unscheduled at the end of the study period. Descriptive statistics were performed. RESULTS: From March 17th 2020 to September 3 rd 2020, 1246 patients with a previous diagnosis of a functional urological disease requiring a surgery were included. The mean follow-up was 140.4 days (± 53.4). Overall, 316 interventions (25.4%) were maintained whereas 74 (5.9%) were canceled, 848 (68.1%) postponed and 8 patients (0.6%) died. At the end of the follow-up, 184 patients (21.7%) were still not rescheduled. If the intervention was postponed, the mean delay between the initial and final date was 85.7 days (± 64.4). CONCLUSION: Overall, more than two thirds of interventions had to be postponed and the mean delay between the initial and final date was about three months.

Impact of radiation therapy on artificial urinary sphincter implantation in male patients: A multicenter study.

AIMS: To evaluate the impact of an history of radiation therapy on the outcomes of artificial urinary sphincter (AUS) implantation in male patients. METHODS: The charts of all patients who underwent AUS implantation for stress urinary incontinence (SUI) after prostate surgery in thirteen centers between 2004 and 2020 were retrospectively reviewed. We excluded patients with neurogenic SUI. Continence rates and incidence of complications, revision and cuff erosion were evaluated. The outcomes in irradiated men were compared to those of non irradiated men. RESULTS: A total of 1277 patients who had an AUS met the inclusion criteria with a median age of 70 years, of which 437 had an history of prior radiotherapy. There was no difference in comorbidities. In irradiated patients, postoperative social continence, urethral atrophy and infection rates were respectively 75.6%, 2.4% and 9.5% and 76.8%, 5.4%, and 5.8% in nonirradiated men (respectively, p = 0.799, p = 0.128, p = 0.148). There were more urethral erosion in irradiated male patients. After a mean follow up of 36.8 months, the explantation free survival was poorer in irradiated patients (p = 0.001). CONCLUSION: These data suggest that pelvic radiotherapy before AUS adversely affect device survival with and increased greater occurrence of infection-erosion and therefore of explantation.

Bayesian predictive model to assess BRCA2 mutational status according to clinical history: Early onset, metastatic phenotype or family history of breast/ovary cancer.

BACKGROUND: Mutations of the BRCA2 gene are the most frequent alterations found in germline DNA from men with prostate cancer (PrCa), but clinical parameters that could better orientate for BRCA2 mutation screening need to be established. METHODS: Germline DNA from 325 PrCa patients (median age at diagnosis: 57 years old) was screened for BRCA2 mutation. The mutation frequency was compared between three subgroups: patients with an age at diagnosis at 55 years old and under (Group I); a personal or family history of breast, uterine or ovarian cancer (Group II); or a metastatic disease (Group III). Frequency of BRCA2 mutations was established for each combination of phenotypes, and compared between patients meeting or not the criteria for each subgroup using Fisher's exact test. Mutual information, direct effect, elasticity and contribution to the mutational status of each phenotype, taking into account overlap between subgroups, were also estimated using Bayesian algorithms. RESULTS: The proportion of BRCA2 mutation was 5.9% in Group I, 10.9% in Group II and 6.9% in Group III. The frequency of BRCA2 mutation was significantly higher among patients of Group II (p = .006), and reached 15.6% among patients of this group who presented a metastatic disease. Mutual information, direct effect, elasticity and contribution to the mutational status were the highest for phenotype II. Fifteen (71.4%) of the 21 BRCA2 mutation carriers had an aggressive form of the disease. Four (19%) of them died from PrCa after a median follow-up duration of 64.5 months. CONCLUSIONS: Our results showed that a higher frequency of BRCA2 mutation carriers is observed, not only among PrCa patients with young onset or a metastatic disease, but also with a personal or a familial history of breast cancer.

Prevalence and Risk Factors of Artificial Urinary Sphincter Revision in Nonneurological Male Patients.

PURPOSE: The main objective of this study was to assess the prevalence and risk factors of male artificial urinary sphincter (AUS) mechanical failures and nonmechanical failures. MATERIALS AND METHODS: The charts of all male patients who underwent AUS implantation between 2004 and 2020 in 16 centers were retrospectively reviewed. Patients with neurogenic stress urinary incontinence (SUI) were excluded as well as revisions/explantations due to infections and/or erosions. The causes of revision were divided into mechanical failures (fluid loss or malfunction from any components of the AUS), nonmechanical failures (urethral atrophy, recurrence/persistence of SUI despite normally functioning device) and other (pump malposition, balloon herniation, hematoma, pain). Failure-free survival analysis was performed both for general and specific causes of revision. Predictors of mechanical and nonmechanical failures were determined by Cox proportional hazards model. RESULTS: A total of 1,020 patients met the inclusion criteria. After a median followup of 20 months, the estimated 5-year and 10-year overall revision-free survival was 60% and 40%, respectively. There were 214 AUS revisions: 59 (27.6%) for mechanical failures, 121 (56.5%) for nonmechanical failures and 34 (15.9%) other causes of revision. In multivariable Cox regression analysis, larger cuff size was the only predictor of overall revisions (HR=1.04 [1.01-1.07]; p=0.01) and revision for nonmechanical failure (HR=1.05 [1.02-1.09]; p=0.004). CONCLUSIONS: Half of the male AUS patients underwent device revision within the first 10 years after implantation. Nonmechanical failures are the primary cause of AUS revision in nonneurological men. Larger cuff size appears to be the main determinant of AUS revision risk.

Transcorporal vs. bulbar artificial urinary sphincter implantation in male patients with fragile urethra.

PURPOSE: To compare transcorporal vs bulbar artificial urinary sphincter (AUS) implantation in men with fragile urethra and to investigate the risk factors of AUS explantation in this population. METHODS: The charts of all male patients who had an AUS implantation between 2004 and 2020 in 16 centers were reviewed retrospectively. The primary endpoint was device explantation-free survival. Only patients with a fragile urethra were included in the present analysis. Fragile urethra was defined as a urethra carrying a high risk of cuff erosion because of prior radiotherapy and/or history of AUS explantation and/or history of urethral stricture surgery. The patients were divided in two groups according to the implantation site: bulbar vs transcorporal. RESULTS: 464 patients were included for analysis. 88 patients underwent a transcorporal AUS implantation and 376 underwent a bulbar AUS implantation. Explantation-free survival was similar in both groups (estimated 5-year explantation free survival rates 55.3% vs. 58.4%; p=0.98). In the subgroup of patients with a history of previous AUS explantation, transcorporal approach tended to bring longer explantation-free survival (2-year explantation-free survival: 61.9% vs. 58.2%; p=0.096). In multivariate analysis, the only risk factor of shorter explantation-free survival was the history of previous AUS explantation (HR=2.65; p=0.01). CONCLUSIONS: Transcorporal AUS implantation was not associated with longer explantation-free survival. History of previous AUS explantation was the only risk factor associated with shorter explantation-free survival and this subgroup of patients may be the only one to draw benefits of transcorporal AUS implantation.

Long-term functional outcomes of augmentation cystoplasty in adult spina bifida patients: A single-center experience in a multidisciplinary team.

AIM: To report the very long-term functional outcomes of augmentation cystoplasty (AC) in adult spina bifida patients. METHODS: All consecutive adult spina bifida patients who underwent AC between 1991 and 2008 were enrolled. Early postoperative complications (Clavien-Dindo classification) and long-term outcomes (voiding modalities, urodynamic parameters, renal function, continence, and quality of life) were assessed. RESULTS: Twenty-eight patients with a median age of 20 years (IQR 17-25) were included. They all underwent AC with a supratrigonal cystectomy (SC). The median follow-up was 13.6 years (IQR 6-16.5). Thirteen early postoperative complications (12 grade I-II, 1 grade III) were observed in 11 patients (39%). Eight patients (29%) had upper urinary tract infections managed with antibiotics, with 2 patients requiring ureteral stents. Bladder stones occurred in 2 patients (7%) and were managed with endoscopy and cystostomy. One bladder perforation was reported. One bladder cancer was observed 26 years after surgery. Creatinine clearance and all urodynamic parameters were significantly improved post-operatively. The overall complication and reoperation rates were 57% and 14%, respectively. At last follow up, the continence rate was 71% (n = 20), with 93% (n = 26) performing intermittent self-catheterization. Quality of life was improved for 71% of patients. CONCLUSION: In adult spina bifida population, AC is a high-risk procedure with an overall complication rate of 57% and a reoperation rate of 14%. However, AC is beneficial to the overall health of the patients since it provides a satisfying continence rate, an improvement of quality of life, and long-term protection of the upper urinary tract.

Comparison of cell cycle progression score with two immunohistochemical markers (PTEN and Ki-67) for predicting outcome in prostate cancer after radical prostatectomy.

PURPOSE: Previous studies of the cell cycle progression (CCP) score in surgical specimens of prostate cancer (PCa) in patients treated by radical prostatectomy (RP) demonstrated significant association with time to biochemical recurrence (BCR). In this study, we compared the ability of the CCP score and the expression of PTEN or Ki-67 to predict BCR in a cohort of patients treated by RP. Finally, we constructed the best predictive model for BCR, incorporating biomarkers and relevant clinical variables. MATERIALS AND METHODS: The study population consisted of 652 PCa patients enrolled in a retrospective cohort and who had RP surgery in French urological centers from 2000 to 2007. RESULTS: Among the 652 patients with CCP scores and complete clinical data, BCR events occurred in 41%, and the median time from surgery to the last follow-up among BCR-free patients was 72 months. In univariate Cox analysis, the continuous CCP score and positive Ki-67 predicted recurrence with a HR of 1.44 (95% CI 1.17-1.75; p = 5.3 × 10-4) and 1.89 (95% CI 1.38-2.57; p = 1.6 × 10-4), respectively. In contrast, PTEN expression was not associated with BCR risk. Of the three biomarkers, only the CCP score remained significantly associated in a multivariable Cox model (p = 0.026). The best model incorporated CAPRA-S and CCP scores as predictors, with HRs of 1.32 and 1.24, respectively. CONCLUSION: The CCP score was superior to the two IHC markers (PTEN and Ki-67) for predicting outcome in PCa after RP.

Complications of non-continent cutaneous urinary diversion in adults with spinal cord injury: a retrospective study.

STUDY DESIGN: Retrospective cohort study. OBJECTIVES: To report the long-term complications of non-continent cutaneous urinary diversion (NCCUD) in adult patients with spinal cord injury (SCI). SETTING: Hospital in Paris, France. METHODS: A retrospective single center study included all adult patients with SCI who underwent an ileal conduit between 1997 and 2014. Early complications were reported according to Clavien-Dindo classification. Long-term complications and reoperation rates were recorded, as well as stoma management and autonomy improvement related to urinary function. RESULTS: One hundred and two patients were included. The surgical indications included failure of intermittent catheterization (n = 43), urethral fistulae due to skin ulcers (n = 50), renal failure (n = 8), recurrent urinary tract infections (n = 9), lithiasis (n = 3), and bladder tumors (n = 2). There were 67 early postoperative complications for 44 patients (43%) leading to an additional surgery in 15 cases: 30 grade I-II, 30 grade III, 6 grade IV, and 1 grade V. A total of 37 late complications were reported for 36 patients (35%): 17 ureteral anastomosis stenosis, 3 stoma hernia, 3 pyocystis (3/15 patients), 7 pyelonephritis, 2 renal failures, 2 ureteral lithiasis, 1 uterine prolapse, 1 incisional hernia, and 1 tumor recurrence. Renal function remained unchanged (p = 0.53). Autonomy related to urinary function was improved in 88% of patients. The correct fitting of the stoma was possible for 81% of the patients. CONCLUSIONS: Despite a perioperative morbidity rate of 43% and a late complication rate of 35%, as a last resort procedure, NCCUD is an end-stage solution in patients with SCI to preserve renal function and achieve autonomy.

Stress urinary incontinence in female neurological patients: long-term functional outcomes after artificial urinary sphincter (AMS 800TM ) implantation.

AIMS: To report the long-term functional outcomes of artificial urinary sphincter (AUS) implantation in female adult neurological patients suffering from stress urinary incontinence (SUI) due to sphincter deficiency. METHODS: Female patients with neurological disease suffering from SUI due to sphincter deficiency who underwent AUS (AMS 800TM ) implantation between 1984 and 2011 were included. Continence rate defined as no need for pads and survival rates of the device without needing explantation or revision using Kaplan-Meier curves were reported. RESULTS: Overall, 26 patients, median age 49.2 years (IQR 28.5-59.7) were included. The median follow-up time was 7.5 years (IQR 3.9-23.8). At the end of follow-up period, 15 patients (57.7%) still had their primary AUS. The AUS was explanted in five women because of infection or erosion. Survival rates, without AUS explantation were 90%, 84%, 84%, and 74% at 5, 10, 15, 20 years, respectively. Survival rates without AUS revision were 75%, 51%, 51%, and 51% at 5, 10, 15, 20 years, respectively. 71.4% of patients with AUS were continent. When considering the 26 initial patients, including the patients in whom the AUS was explanted, the continence rate was 57.7%. CONCLUSIONS: For treating neurogenic sphincter deficiency in the long term, the AMS 800TM can offer a satisfying rate of continence to female patients, with a tolerable rate of explantation and revision.

Apparent diffusion coefficient value is a strong predictor of unsuspected aggressiveness of prostate cancer before radical prostatectomy.

PURPOSE: To evaluate the use of multiparametric MRI (mp MRI) parameters in order to predict prostate cancer aggressiveness as defined by pathological Gleason score or molecular markers in a cohort of patients defined with a Gleason score of 6 at biopsy. METHODS: Sixty-seven men treated by radical prostatectomy (RP) for a low grade (Gleason 6) on biopsy and mp MRI before biopsy were selected. The cycle cell proliferation (CCP) score assessed by the Prolaris test and Ki-67/PTEN expression assessed by immunohistochemistry were quantified on the RP specimens. RESULTS: 49.25 % of the cancers were undergraded on biopsy compared to the RP specimens. Apparent diffusion coefficient (ADC) < 0.80 × 10(-3) mm(2)/s (P value 0.003), Likert score >4 (P value 0.003) and PSA density >0.15 ng/ml/cc (P value 0.035) were significantly associated with a higher RP Gleason score. Regarding molecular markers of aggressiveness, ADC < 0.80 × 10(-3) mm(2)/s and Likert score >4 were also significantly associated with a positive staining for Ki-67 (P value 0.039 and 0.01, respectively). No association was found between any analyzed MRI or clinical parameter and the CCP score. CONCLUSION: Decreasing ADC value is a stronger indicator of aggressive prostate cancer as defined by molecular markers or postsurgical histology than biopsy characteristics.

The subclassification of papillary renal cell carcinoma does not affect oncological outcomes after nephron sparing surgery.

OBJECTIVES: To evaluate the oncological outcomes of papillary renal cell carcinoma (pRCC) following nephron sparing surgery (NSS) and to determine whether the subclassification type of pRCC could be a prognostic factor for recurrence, progression, and specific death. MATERIALS AND METHODS: An international multicentre retrospective study involving 19 institutions and the French network for research on kidney cancer was conducted after IRB approval. We analyzed data of all patients with pRCC who were treated by NSS between 2004 and 2014. RESULTS: We included 486 patients. Tumors were type 1 pRCC in 369 (76 %) cases and type 2 pRCC in 117 (24 %) cases. After a mean follow-up of 35 (1-120) months, 8 (1.6 %) patients experienced a local recurrence, 12 (1.5 %) had a metastatic progression, 24 (4.9 %) died, and 7 (1.4 %) died from cancer. Patients with type I pRCC had more grade II (66.3 vs. 46.1 %; p < 0.001) and less grade III (20 vs. 41 %; p < 0.001) tumors. Three-year estimated cancer-free survival (CFS) rate for type 1 pRCC was 96.5 % and for type 2 pRCC was 95.1 % (p = 0.894), respectively. Three-year estimated cancer-specific survival rate for type 1 pRCC was 98.4 % and for type 2 pRCC was 97.3 % (p = 0.947), respectively. Tumor stage superior to pT1 was the only prognostic factor for CFS (HR 3.5; p = 0.03). CONCLUSION: Histological subtyping of pRCC has no impact on oncologic outcomes after nephron sparing surgery. In this selected population of pRCC tumors, we found that tumor stage is the only prognostic factor for cancer-free survival.

Accuracy of the prostate health index versus the urinary prostate cancer antigen 3 score to predict overall and significant prostate cancer at initial biopsy.

BACKGROUND: It remains unclear whether the Prostate Health Index (PHI) or the urinary Prostate-Cancer Antigen 3 (PCA-3) score is more accurate at screening for prostate cancer (PCa). The aim of this study was to prospectively compare the accuracy of PHI and PCA-3 scores to predict overall and significant PCa in men undergoing an initial prostate biopsy. METHODS: Double-blind assessments of PHI and PCA-3 were conducted by referent physicians in 138 patients who subsequently underwent trans-rectal ultrasound-guided prostate biopsy according to a 12-core scheme. Predictive accuracies of PHI and PCA-3 were assessed using AUC and compared according to the DeLong method. Diagnostic performances with usual cut-off values for positivity (i.e., PHI >40 and PCA-3 >35) were calculated, and odds ratios associated with predicting PCa overall and significant PCa as defined by pathological updated Epstein criteria (i.e., Gleason score ≥7, more than three positive cores, or >50% cancer involvement in any core) were estimated using logistic regression. RESULTS: Prevalences of overall and significant PCa were 44.9% and 28.3%, respectively. PCA-3 (AUC = 0.71) was the most accurate predictor of PCa overall, and significantly outperformed PHI (AUC = 0.65; P = 0.03). However, PHI (AUC = 0.80) remained the most accurate predictor when screening exclusively for significant PCa and significantly outperformed PCA-3 (AUC = 0.55; P = 0.03). Furthermore, PCA-3 >35 had the best accuracy, and positive or negative predictive values when screening for PCa overall whereas these diagnostic performances were greater for PHI >40 when exclusively screening for significant PCa. PHI > 40 combined with PCA-3 > 35 was more specific in both cases. In multivariate analyses, PCA-3 >35 (OR = 5.68; 95%CI = [2.21-14.59]; P < 0.001) was significantly correlated with the presence of PCa overall, but PHI >40 (OR = 9.60; 95%CI = [1.72-91.32]; P = 0.001) was the only independent predictor for detecting significant PCa. CONCLUSIONS: Although PCA-3 score is the best predictor for PCa overall at initial biopsy, our findings strongly indicate that PHI should be used for population-based screening to avoid over-diagnosis of indolent tumors that are unlikely to cause death.

Multiparametric Magnetic Resonance Imaging Predicts Postoperative Pathology but Misses Aggressive Prostate Cancers as Assessed by Cell Cycle Progression Score.

PURPOSE: We identified prognostic biomarkers in prostate cancer by a radiogenomics strategy that integrates gene expression using the cell cycle progression score and medical images. MATERIALS AND METHODS: We obtained institutional review board approval and written informed consent from 106 men with prostate cancer, including 60% at low risk, who underwent multiparametric magnetic resonance imaging before radical prostatectomy was done and a cell cycle progression score was determined. The correlation between the results of multiparametric magnetic resonance imaging and Gleason grade or cell cycle progression score was assessed by logistic regression. RESULTS: Patients with primary Gleason grade greater than 3 had a longer median maximal tumor diameter (13 vs 10 mm) and a lower median apparent diffusion coefficient (0.745 vs 0.88×10(-3) mm2 per second, each p=0.0001) than those with primary Gleason grade 3 or less. Maximal diameter 10 mm or greater (OR 4.9, 95% CI 1.7 to 14.0, p=0.0012) and apparent diffusion coefficient 0.80×10(-3) mm2 per second or less (OR 7.5, 95% CI 3.0 to 18.7, p<0.0001) were significantly associated with primary Gleason grade greater than 3. The combined measure of maximal diameter less than 10 mm and apparent diffusion coefficient greater than 0.80×10(-3) mm2 per second identified only index lesions harboring primary Gleason grade 3. However, 7 of those lesions showed a molecular pattern of high risk lethal prostate cancer (cell cycle progression score greater than 0). CONCLUSIONS: Multiparametric magnetic resonance imaging is able to predict low and high risk Gleason scores in the tumor. However, the cell cycle progression score did not completely match the imaging result. These findings suggest that management of early stages prostate cancer could strongly benefit by performing magnetic resonance imaging targeted biopsy coupled with molecular analysis.
