RESUMO
BACKGROUND: Ureteral cancer is a rare cancer. This study aimed to provide an up-to-date and comprehensive analysis on the global trends of ureteral cancer incidence and its association with lifestyle and metabolic risk factors. METHODS: The incidence of ureteral cancer was estimated from the Cancer Incidence in Five Continents Plus and Global Cancer Observatory databases. We analyzed the (1) global incidence of ureteral cancer by region, country, sex, and age group by age-standardized rates (ASR); (2) associated risk factors on a population level by univariable linear regression with logarithm transformation; and (3) incidence trend of ureteral cancer by sex and age group in different countries by Average Annual Percentage Change (AAPC). RESULTS: The global age-standardized rate of ureteral cancer incidence in 2022 was 22.3 per 10,000,000 people. Regions with higher human development index (HDI), such as Europe, Northern America, and East Asia, were found to have a higher incidence of ureteral cancer. Higher HDI and gross domestic product (GDP) and a higher prevalence of smoking, alcohol drinking, physical inactivity, unhealthy dietary, obesity, hypertension, diabetes, and lipid disorder were associated with higher incidence of ureteral cancer. An overall increasing trend of ureteral cancer incidence was observed for the past decade, especially among the female population. CONCLUSIONS: Although ureteral cancer was relatively rare, the number of cases reported was rising over the world. The rising trends among females were more evident compared with the other subgroups, especially in European countries. Further studies could be conducted to examine the reasons behind these epidemiological changes and confirm the relationship with the risk factors identified.

OBJECTIVE: To report the learning curve of multiple operators for fusion magnetic resonance imaging (MRI) targeted biopsy and to determine the number of cases needed to achieve proficiency. MATERIALS AND METHODS: All adult males who underwent fusion MRI targeted biopsy between February 2012 and July 2021 for clinically suspected prostate cancer (PCa) in a single centre were included. Fusion transrectal MRI targeted biopsy was performed under local anaesthesia using the Koelis platform. Learning curves for segmentation of transrectal ultrasonography (TRUS) images and the overall MRI targeted biopsy procedure were estimated with locally weighted scatterplot smoothing by computing each operator's timestamps for consecutive procedures. Non-risk-adjusted cumulative sum (CUSUM) methods were used to create learning curves for clinically significant (i.e., International Society of Urological Pathology grade ≥ 2) PCa detection. RESULTS: Overall, 1721 patients underwent MRI targeted biopsy in our centre during the study period. The median (interquartile range) times for TRUS segmentation and for the MRI targeted biopsy procedure were 4.5 (3.5, 6.0) min and 13.2 (10.6, 16.9) min, respectively. Among the 14 operators with experience of more than 50 cases, a plateau was reached after 40 cases for TRUS segmentation time and 50 cases for overall MRI targeted biopsy procedure time. CUSUM analysis showed that the learning curve for clinically significant PCa detection required 25 to 45 procedures to achieve clinical proficiency. Pain scores ranged between 0 and 1 for 84% of patients, and a plateau phase was reached after 20 to 100 cases. CONCLUSIONS: A minimum of 50 cases of MRI targeted biopsy are necessary to achieve clinical and technical proficiency and to reach reproducibility in terms of timing, clinically significant PCa detection, and pain.

OBJECTIVE: To evaluate the impact of adjuvant therapy on oncological outcomes in patients with intermediate-risk non-muscle-invasive bladder cancer (NMIBC), as due to the poorly-defined and overlapping diagnostic criteria optimal decision-making remains challenging in these patients. PATIENTS AND METHODS: In this multicentre study, patients treated with transurethral resection of bladder tumour for Ta disease were retrospectively analysed. All patients with low- or high-risk NMIBC were excluded from the analysis. Associations between adjuvant therapy administration with recurrence-free survival (RFS) and progression-free survival (PFS) rates were assessed in Cox regression models. RESULTS: A total of 2206 patients with intermediate-risk NMIBC were included in the analysis. Among them, 1427 patients underwent adjuvant therapy, such as bacille Calmette-Guérin (n = 168), or chemotherapeutic agents, such as mitomycin C or epirubicin (n = 1259), in different regimens up to 1 year. The median (interquartile range) follow-up was 73.3 (38.4-106.9) months. The RFS at 1 and 5 years in patients treated with adjuvant therapy and those without were 72.6% vs 69.5% and 50.8% vs 41.3%, respectively. Adjuvant therapy was associated with better RFS (hazard ratio [HR] 0.79, 95% confidence interval [CI] 0.70-0.89, P < 0.001), but not with PFS (P = 0.09). In the subgroup of patients aged ≤70 years with primary, single Ta Grade 2 <3 cm tumours (n = 328), adjuvant therapy was not associated with RFS (HR 0.71, 95% CI 0.50-1.02, P = 0.06). While in the subgroup of patients with at least one risk factor including patient age >70 years, tumour multiplicity, recurrent tumour and tumour size ≥3 cm (n = 1878), adjuvant intravesical therapy was associated with improved RFS (HR 0.78, 95% CI 0.68-0.88, P < 0.001). CONCLUSION: In our study, patients with intermediate-risk NMIBC benefit from adjuvant intravesical therapy in terms of RFS. However, in patients without risk factors, adjuvant intravesical therapy did not result in a clear reduction in the recurrence rate.
RESUMO
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.
RESUMO
OBJECTIVES: To assess the risk of venous thromboembolic events (VTEs) and bleeding with or without thromboprophylaxis during neoadjuvant chemotherapy in bladder cancer patients scheduled for radical cystectomy. MATERIALS AND METHODS: We conducted a retrospective cohort study in 4886 patients with non-metastatic bladder cancer undergoing cystectomy across 28 centres in 13 countries between 1990 and 2021. Inverse probability weighting analyses were performed to estimate the effect of thromboprophylaxis on VTE and bleeding. RESULTS: In 147 patients (3%) VTEs were recorded within the first year. These occurred a median (interquartile range [IQR]) of 127 (82-198) days after bladder cancer diagnosis. Bleeding events occurred in 131 patients (3%) within the first year. These occurred a median (IQR) of 101 (83-171) days after cancer diagnosis. In inverse probability weighting analyses, compared to patients without thromboprophylaxis during chemotherapy, patients with thromboprophylaxis had not only a lower risk of VTE (hazard ratio [HR] 0.32, 95% confidence interval [CI] 0.12-0.81; P = 0.016) but also a lower bleeding risk (HR 0.03, 95% CI 0.09-0.12; P <0.0001). The retrospective nature of the study was its main limitation. CONCLUSIONS: In this retrospective analysis, the benefit of thromboprophylaxis during neoadjuvant chemotherapy before cystectomy is in line with data from randomised trials in other malignancies. Our data suggest thromboprophylaxis is protective against VTEs and should be the standard of care during neoadjuvant chemotherapy.
RESUMO
PURPOSE: Testicular cancer (TC) predominantly affects young men and early detection enhances survival. However, uncertainty surrounds the impact of population-wide screening. Testicular self-examination (TSE) is a simple detection method but there is a gap in current practices that needs to be assessed. Our goal was to assess the perceptions and knowledge of male subjects in the general population (MP) and general practitioners (GPs) regarding TSE for TC. METHODS: Two distinct surveys evaluating knowledge and perceptions of TSE for TC were administered to GPs and MP, aged 15â45-years. Factors that could favour the realisation of TSE or improve the knowledge of TC were evaluated by multivariable logistic regression. RESULTS: Overall, 1048 GPs (mean (SD) age: 35.1 ± 10.3 years) and 1032 MP (mean (SD) age: 27 ± 8.2 years) answered the survey. Among the GPs, only 93 (8.9%) performed scrotal examination for TC screening. Although the majority (n = 993, 94.8%) were aware of the age of onset of TC, most (n = 768, 73.3%) did not know the overall survival rate from TC. GPs familiar with the guidelines were more likely to explain TSE to their patients (OR = 2.5 [95% CI 1.5â4.1]; p < 0.01). Among the MP, 800 (77.5%) admitted that they did not know how to perform TSE and 486 (47.1%) did not know the main symptoms associated with TC. MP who had already undergone TC screening were more likely to be familiar with the main symptoms (OR = 2.1 [95% CI 1.6â2.7]; p < 0.001) and MP who knew someone with TC or who had already undergone TC screening were more likely to be aware of the correct prevalence of TC (OR = 1.9 [95% CI 1.3â2.7], p < 0.01; and OR = 1.6 [95% CI 1.2â2.1], p < 0.01; respectively). CONCLUSION: The knowledge of both GPs and MP regarding TC could be improved. TSE screening and knowing someone close with TC improved the awareness of our subjects.

CONTEXT: Radical nephroureterectomy (RNU) with bladder cuff resection is the standard treatment in patients with high-risk upper tract urothelial cancer (UTUC). However, it is unclear which specific surgical technique may lead to improve oncological outcomes in term of intravesical recurrence (IVR) in patients with UTUC. OBJECTIVE: To evaluate the efficacy of surgical techniques and approaches of RNU in reducing IVR in UTUC patients. EVIDENCE ACQUISITION: Three databases were queried in January 2024 for studies analyzing UTUC patients who underwent RNU. The primary outcome of interest was the rate of IVR among various types of surgical techniques and approaches of RNU. EVIDENCE SYNTHESIS: Thirty-one studies, comprising 1 randomized controlled trial and 1 prospective study, were included for a systematic review and meta-analysis. The rate of IVR was significantly lower in RNU patients who had an early ligation (EL) of the ureter compared to those who did not (HR: 0.64, 95% CI: 0.44-0.94, p = 0.02). Laparoscopic RNU significantly increased the IVR compared to open RNU (HR: 1.28, 95% CI: 1.06-1.54, p < 0.001). Intravesical bladder cuff removal significantly reduced the IVR compared to both extravesical and transurethral bladder cuff removal (HR: 0.65, 95% CI: 0.51-0.83, p = 0.02 and HR: 1.64, 95% CI: 1.15-2.34, p = 0.006, respectively). CONCLUSIONS: EL of the affected upper tract system, ureteral management, open RNU, and intravesical bladder cuff removal seem to yield the lowest IVR rate in patients with UTUC. Well-designed prospective studies are needed to conclusively elucidate the optimal surgical technique in the setting of single post-operative intravesical chemotherapy.

INTRODUCTION: There is limited evidence on the outcomes of robotic partial nephrectomy (RPN) and open partial nephrectomy (OPN) in obese patients (BMI ≥ 30 kg/m2). In this study, we aimed to compare perioperative and oncological outcomes of RPN and OPN. METHODS: We relied on data from patients who underwent PN from 2009 to 2017 at 16 departments of urology participating in the UroCCR network, which were collected prospectively. In an effort to adjust for potential confounders, a propensity-score matching was performed. Perioperative outcomes were compared between OPN and RPN patients. Disease-free survival (DFS) and overall survival (OS) were estimated using the Kaplan-Meier method and compared using the log-rank test. RESULTS: Overall, 1277 obese patients (932 robotic and 345 open were included. After propensity score matching, 166 OPN and 166 RPN individuals were considered for the study purposes; no statistically significant difference among baseline demographic or tumor-specific characteristics was present. A higher overall complication rate and major complications rate were recorded in the OPN group (37 vs. 25%, p = 0.01 and 21 vs. 10%, p = 0.007; respectively). The length of stay was also significantly longer in the OPN group, before and after propensity-score matching (p < 0.001). There were no significant differences in Warm ischemia time (p = 0.66), absolute change in eGFR (p = 0.45) and positive surgical margins (p = 0.12). At a median postoperative follow-up period of 24 (8-40) months, DFS and OS were similar in the two groups (all p > 0.05). CONCLUSIONS: In this study, RPN was associated with better perioperative outcomes (improvement of major complications rate and LOS) than OPN. The oncological outcomes were found to be similar between the two approaches.

PURPOSE: We evaluate the efficacy and safety of combining antimuscarinics with alpha-blockers to treat storage symptoms in men with benign prostatic hyperplasia. MATERIALS AND METHODS: Searches were carried out on PubMed, MEDLINE, EMBASE, and Cochrane databases to identify randomized, placebo-controlled trials published before February 15, 2022, assessing the efficacy or safety of antimuscarinics in men with benign prostatic hyperplasia treated with alpha-blockers. Further meta-analyses were performed using standardized mean difference and risk ratio. RESULTS: A total of 12 randomized trials were included in the systematic review. The meta-analysis showed no impact of antimuscarinics on the number of urgencies per day (SMD -0.23 [95%CI: -0.64; -0.17]; P = .21). However, the use of antimuscarinics was associated with a small reduction of micturition episodes per day (SMD -0.19 [95%CI: -0.37; -0.01]; P = .045). With regard to side effects, post-void residual increased slightly in patients treated with antimuscarinics (SMD 0.26 [95%CI: 0.15; 0.37]; P < .01). In addition, there was a higher risk of acute urinary retention (RR 3.26 [95%CI: 1.35; 7.86]; P = .02), dry mouth (RR 3.43 [95%CI: 1.86; 6.32]; P < .001), and constipation (RR 2.92 [95%CI: 1.48; 5.73]; P < .001) with the use of antimuscarinics. Finally, the risk of treatment interruption due to adverse events was higher for the patients treated with antimuscarinics (RR 1.74 [95%CI: 1.27; 2.38]; P < .01). CONCLUSIONS: The addition of antimuscarinics to alpha-blockers was not associated with a substantial reduction in urgencies and micturition episodes in benign prostatic hyperplasia patients with storage symptoms. In addition, the toxicity profile was not in favor of antimuscarinic use in these patients.

PURPOSE: Treatment options for the management of upper tract urothelial cancer are based on accurate staging. However, the performance of conventional cross-sectional imaging for clinical lymph node staging (N-staging) remains poorly investigated. This study aims to evaluate the diagnostic accuracy of conventional cross-sectional imaging for upper tract urothelial cancer N-staging. MATERIALS AND METHODS: This study was a multicenter, retrospective, observational study. We included 865 nonmetastatic (M0) upper tract urothelial cancer patients treated with curative intended surgery and lymph node dissection who had been staged with conventional cross-sectional imaging before surgery. We compared clinical (c) and pathological (p) N-staging results to evaluate the concordance of node-positive (N+) and node-negative (N0) disease and calculate cN-staging's diagnostic accuracy. RESULTS: Conventional cross-sectional imaging categorized 750 patients cN0 and 115 cN+. Lymph node dissection categorized 641 patients pN0 and 224 pN+. The cN-stage was pathologically downstaged in 6.8% of patients, upstaged in 19%, and found concordant in 74%. The sensitivity and specificity of cN-staging were 25% (95% CI 20; 31) and 91% (95% CI 88; 93). Positive and negative likelihood ratios were 2.7 (95% CI 2.0; 3.8) and 0.83 (95% CI 0.76; 0.89). The area under the receiver operating characteristics curve (0.58, 95% CI 0.55; 0.61) revealed low diagnostic accuracy. CONCLUSIONS: Conventional cross-sectional imaging had low sensitivity in detecting upper tract urothelial cancer pN+ disease. However, cN+ increased the likelihood of pN+ by almost threefold. Thus, conventional cross-sectional imaging is a rule-in but not a rule-out test. Lymph node dissection should remain the standard during extirpative upper tract urothelial cancer surgery to obtain accurate N-staging. cN+ could be a strong argument for early systemic treatment.

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.

OBJECTIVE: To evaluate prospectively the effects of surgical excision of renal tumours on blood pressure (BP). PATIENTS AND METHODS: In a multicentre prospective study, we evaluated 200 patients who underwent nephrectomy for renal tumour between 2018 and 2020 at seven departments of the French Network for Kidney Cancer, the UroCCR. All patients had localized cancer without pre-existing hypertension (HTN). Blood pressure was measured the week before nephrectomy, and at 1 month and 6 months after nephrectomy, according to the recommendations for home BP monitoring. Plasma renin was measured 1 week before surgery and 6 months after surgery. The primary endpoint was the occurrence of de novo HTN. The secondary endpoint was clinically significant increase in BP at 6 months, defined by an increase in systolic and/or diastolic ambulatory BP ≥10 mmHg or requirement for medical antihypertensive treatment. RESULTS: Blood pressure and renin measurements were available for 182 (91%) and 136 patients (68%), respectively. We excluded from the analysis 18 patients who had undeclared HTN detected on preoperative measurements. At 6 months, 31 patients (19.2%) had de novo HTN and 43 patients (26.3%) had a significant increase in their BP. Type of surgery was not associated with an increased risk of HTN (21.7% partial nephrectomy [PN] vs 15.7% radical nephrectomy [RN]; P = 0.59). There was no difference between plasmatic renin levels before and after surgery (18.5 vs 16; P = 0.46). In multivariable analysis, age (odds ratio [OR] 1.07, 95% confidence interval [CI] 1.02-1.12; P = 0.03) and body mass index (OR 1.14, 95% CI 1.03-1.26; P = 0.01) were the only predictors of de novo HTN. CONCLUSION: Surgical treatment of renal tumours is associated with significant changes in BP, with de novo HTN occurring in almost 20% of the patients. These changes are not impacted by the type of surgery (PN vs RN). Patients who are scheduled to undergo kidney cancer surgery should be informed of these findings and have their BP closely monitored after the operation.
RESUMO
OBJECTIVES: To assess the impact of pathological upstaging from clinically localized to locally advanced pT3a on survival in patients with renal cell carcinoma (RCC), as well as the oncological safety of various surgical approaches in this setting, and to develop a machine-learning-based, contemporary, clinically relevant model for individual preoperative prediction of pT3a upstaging. MATERIALS AND METHODS: Clinical data from patients treated with either partial nephrectomy (PN) or radical nephrectomy (RN) for cT1/cT2a RCC from 2000 to 2019, included in the French multi-institutional kidney cancer database UroCCR, were retrospectively analysed. Seven machine-learning algorithms were applied to the cohort after a training/testing split to develop a predictive model for upstaging to pT3a. Survival curves for disease-free survival (DFS) and overall survival (OS) rates were compared between PN and RN after G-computation for pT3a tumours. RESULTS: A total of 4395 patients were included, among whom 667 patients (15%, 337 PN and 330 RN) had a pT3a-upstaged RCC. The UroCCR-15 predictive model presented an area under the receiver-operating characteristic curve of 0.77. Survival analysis after adjustment for confounders showed no difference in DFS or OS for PN vs RN in pT3a tumours (DFS: hazard ratio [HR] 1.08, P = 0.7; OS: HR 1.03, P > 0.9). CONCLUSIONS: Our study shows that machine-learning technology can play a useful role in the evaluation and prognosis of upstaged RCC. In the context of incidental upstaging, PN does not compromise oncological outcomes, even for large tumour sizes.

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.
RESUMO
BACKGROUND: Penile prothesis (PP) is a recommended treatment for erectile dysfunction that is refractory to less invasive treatments, but there are few validated tools to assess patient satisfaction. AIM: The aim of this study was to assess patient satisfaction after PP implantation using the French Satisfaction Survey for Inflatable Penile Implant (SSIPI) questionnaire. METHODS: Demographic, clinical, and perioperative data were collected from all consecutive patients who underwent PP implantation in our center between 2016 and 2021. The French SSIPI questionnaire was completed during a telephone call with each patient by an independent investigator. OUTCOMES: A good functional result was considered when the total SSIPI score was >48, corresponding to a score of >3 for each item. RESULTS: The median global SSIPI score for the cohort was 66 (interquartile range [IQR], 60-73), and 53 (89.8%) patients were satisfied. The appearance of the penis with the PP was the item that had the lowest score for satisfaction (median score 23 [IQR, 19-26]), while the patients reported almost no pain (median score 10 [IQR, 9-10]). When patients with a total score of ≤64 were compared with those with a score of >64, PP size was significantly greater in the group with better functional results (P = .03). CLINICAL IMPLICATIONS: Assessment of patient satisfaction with a PP is important because this is the main criterion used to judge the success of surgery. STRENGTHS AND LIMITATIONS: To our knowledge, this is the first study to evaluate the satisfaction of patients with a PP using the French-validated version of SSIPI questionnaire. However, patients came from a single center and the population size was small. CONCLUSION: Almost 90% of patients with a PP were satisfied with the device when satisfaction was assessed using the SSIPI questionnaire.

PURPOSE: The natural history of prostate cancer (PC) almost always evolves to castration-resistant prostate cancer (CRPC) status, sometimes comprising pure or mixed neuroendocrine prostate cancers (NEPC) differentiation. In CRPC, monitoring using only prostate-specific antigen (PSA) is not optimal since neuroendocrine differentiated cells do not secrete PSA. Thus, monitoring with PSA and chromogranin A (CgA) may be useful. This review aims to evaluate evidence for the usefulness of CgA assessments during the monitoring of prostate cancer. METHOD: This review was based on three recent meta-analysis concerning CgA and prostate cancer. Further data were obtained from PubMed and Embase databases by searches using keywords, including chromogranin A and prostate cancer. RESULTS: CgA levels remain largely unchanged during the early PC evolution. The development of NEPC is characterised by lower PSA secretion and increased CgA secretion. Data supporting the prognostic value of high CgA baseline levels for survival are contrasting and scarce. However, increasing CgA levels early during treatment of metastatic (m)CRPC suggests resistance to treatment and predicts shorter survival, particularly in men with high baseline levels of CgA levels. In men with mCRPC, the first-line chemotherapy may be more appropriate than other agents when baseline CgA levels are high. Also, increasing CgA levels during treatment may indicate disease progression and may warrant a change of therapy. CONCLUSION: CgA monitoring at baseline and regularly during mCRPC management may be useful for monitoring disease evolution. An increased CgA baseline levels and increasing CgA levels may assist physicians with choosing and modifying therapy.

PURPOSE: Despite surgical and anesthetic progress, radical cystectomy for bladder cancer remains one of the most morbid surgeries in urology. The objective of our study was to describe intraoperative complications and to assess the impact of surgical approach on morbidity. METHODS: We retrospectively reviewed medical records of patients treated by radical cystectomy for localized muscle invasive bladder cancer between 2015 and 2020, following the Martin et al. criteria for complications reports. All intraoperative adverse events were graded according to the EAUiaiC scores. Multivariate regression models were used to determine predicting factors of complications. RESULTS: A total of 318 patients were included for analysis. Among them, 17 patients (5.4%) presented an intraoperative complication. No preoperative oncological or clinical factor was associated with the occurrence of an intraoperative complication. Surgical approach had no impact on morbidity. Both overall survival (HR 2.02; CI95% 0.87-4.68; p = 0.101) and recurrence-free survival (HR 1.856; CI95% 0.804-4.284; p = 0.147) were not associated with intraoperative complication. CONCLUSION: Radical cystectomy remains a highly morbid surgery and surgical approach did not improve the complication rate. Perioperative morbidity has a significant impact on patient survival. The association between intraoperative and postoperative complications illustrates the cumulative effect of perioperative events that are associated with survival.

PURPOSE: To summarize evidence regarding the use of neoadjuvant (NAC) and adjuvant chemotherapy (AC) among patients treated with radical nephroureterectomy (RNU). METHODS: A comprehensive literature search of PubMed (MEDLINE), EMBASE and the Cochrane library was performed to identify any original or review article on the role of perioperative chemotherapy for UTUC patients treated with RNU. RESULTS: With regards to NAC, retrospective studies consistently suggested that it may be associated with better pathological downstaging (pDS) ranging from 10.8 to 80% and complete response (pCR) ranging from 4.3 to 15%, while decreasing the risk of recurrence and death as compared to RNU alone. Even higher pDS ranging from 58 to 75% and pCR ranging from 14 to 38% were observed in single-arm phase II trials. With regards to AC, retrospective studies provided conflicting results although the largest report from the National Cancer Database suggested an overall survival benefit in pT3-T4 and/or pN + patients. In addition, a phase III randomized controlled trial showed that the use of AC was associated with a disease-free survival benefit (HR = 0.45; 95% CI = [0.30-0.68]; p = 0.0001) in pT2-T4 and/or pN + patients with acceptable toxicity profile. This benefit was consistent in all subgroups analyzed. CONCLUSIONS: Perioperative chemotherapy improves oncological outcomes associated with RNU. Given the impact of RNU on renal function, the rational is stronger for the use of NAC which impacts final pathology and potentially prolongs survival. However, the level of evidence is stronger for the use of AC that has been proven to decrease the risk of recurrence after RNU with a potential survival benefit.

PURPOSE: To report perioperative, renal function and oncological outcomes of robot-assisted radical nephroureterectomy (RNU) for patients with upper tract urothelial carcinoma (UTUC). METHODS: This was a retrospective single-arm monocentric study including all consecutive UTUC patients treated with robot-assisted RNU at our institution between 2014 and 2022. Descriptive statistics with median and interquartile range (IQR) for continuous variables and numbers with frequencies for categorical variables were used to report perioperative and renal function outcomes while Kaplan-Meier curves were computed to present extravesical and intravesical recurrence-free survival(RFS) as well as cancer-specific (CSS) and overall survival (OS) with the corresponding 95% confidence intervals(CIs). RESULTS: Overall, 70 patients with a median age of 69.6 [63.3-74.9] years were included in our study. With regards to perioperative outcomes, the median operative time was 157 [130-182] min with a median blood loss of 200 [100-300] cc. Intraoperative complications occurred in 4 (5.7%) patients but no conversion to open or laparoscopic surgery was required. Postoperative complications occurred in 9 (12.9%) patients, including 5 (7.1%) with grade ≥ 3 complications according to the Clavien-Dindo classification. The median length of stay was 4 [3-6] days. With regards to renal function outcomes, the median postoperative loss in estimated glomerular filtration rate at discharge was 16 [10.25-26] mL/min/1.73 m2. With regards to oncological outcomes, the 3-year extravesical and intravesical RFS, CSS and OS rates were 73.6 [62.8-86.2]%, 68.1 [54.6-85]%, 82.5 [72-94.4]% and 75.3 [63.4-89.5]%, respectively. CONCLUSION: We report favorable perioperative and oncological outcomes with expected decrease in renal function after robot-assisted RNU for patients with UTUC.

BACKGROUND: Upper urinary tract urothelial carcinoma (UTUC) is often locally advanced at initial diagnosis and is associated with high recurrence and mortality rates after radical nephroureterectomy (RNU). Adjuvant platinum-based chemotherapy has shown a recurrence-free survival benefit in a randomised phase III trial, while neoadjuvant treatment seems promising in retrospective series. On the contrary, little is known about the role of perioperative immunotherapy and its combination with chemotherapy for UTUC patients, although initial positive results have been published for muscle-invasive bladder cancer. STUDY DESIGN AND ENDPOINTS: Against this backdrop, we are running a multi-centre single-arm phase 2 trial of neoadjuvant Durvalumab, a monoclonal antibody targeting programmed cell death ligand 1, combined with Gemcitabine and Cisplatin or Carboplatin for high-risk UTUC patients. The primary outcome is pathological complete response rate at RNU. Secondary endpoints include the partial pathological response rate, safety, as well as disease-free and overall survival. A biomarker analysis is also planned. PATIENTS AND INTERVENTIONS: Included patients must have a good performance status and harbour a non-metastatic UTUC, considered at high risk of progression, defined as either biopsy-proven high-grade disease or invasive features at imaging with or, more recently, without high-grade cytology at the multidisciplinary team discretion, as specified in the latest amendment. Enrolled patients receive 3 cycles of neoadjuvant immuno-chemotherapy before RNU, and the standard of care thereafter. The trial is registered as NCT04617756 and is supervised by an independent data monitoring committee.
