Global burden, risk factors, and temporal trends of ureteral cancer: a comprehensive analysis of cancer registries.

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.

Artificial Urinary Sphincter Implants in Men: A National Health Care Data System-Based Study to Assess Reinterventions in France.

PURPOSE: Significant concerns remain regarding the long-term outcomes of AMS 800 artificial urinary sphincter (AUS) implants in men. The objective was to assess the long-term AUS reintervention (replacement or removal) rates after a first-ever AUS implantation. MATERIALS AND METHODS: This population-based retrospective cohort study included all men age ≥ 18 years in France who underwent a first-ever AUS implantation (identified using a unique device identifier) for male stress urinary incontinence (SUI) after prostate cancer (PCa) or benign prostatic hyperplasia (BPH) treatment, between January 1, 2006, and December 31, 2018. The primary outcome was reintervention-free survival rates (replacements and removals), estimated using the Kaplan-Meier method. Secondary outcomes were replacement and removal. A multivariable Cox proportional hazards model was used to assess associations between patient and hospital factors and the hazard of reintervention. RESULTS: The study included 8475 men with a median age of 69 years (IQR, 65-74) and a median follow-up time of 6 years (IQR, 3-9). Reintervention-free survival was 71% (95% CI, 70-72) at 2 years, 57% (95% CI, 55-58) at 5 years, and 40% (95% CI, 38-41) at 10 years. Reintervention-free survival was lower after BPH surgery, after radiotherapy combined with RP, and in centers performing fewer implantations. Removal-free survival was 83% (95% CI, 83%-84%) at 2 years, 75% (95% CI, 74%-76%) at 5 years, and 66% (95% CI, 65%-68%) at 10 years. CONCLUSIONS: Among men undergoing AUS implantation for SUI because of PCa or BPH treatment, the probability of reintervention was 29% within 2 years after implantation. The median time to reintervention was 6.6 years (IQR, 6.4-7.1), and the reintervention-free survival rate at 10 years was 40%. These insights can inform therapeutic decision making for patients and surgeons during the management of male SUI.

Long-term recurrence risk, metastatic potential and length of cystoscopic surveillance of low-grade non-muscle invasive bladder cancer.

PURPOSE: Patients with Ta low-grade (LG) non-muscle invasive bladder cancer (NMIBC) rarely develop metastases or die from it. Long-term data are scant and length of follow-up poorly defined. MATERIAL AND METHODS: This retrospective study included 521 patients diagnosed with primary TaLG (n=491) or papillary urothelial neoplasm of low malignant potential (PUNLMP, n=30) from 1989-2019 at an Academic center. Patient data was acquired using patient records chart review and a bladder cancer informatics registry at the center. Risk of recurrence, progression in stage, to muscle invasion, metastases and death due to BC were analyzed. RNAseq assessed the transcriptomic profiles of four TaLG that metastasized. Interobserver variability in pathological grading (WHO 2004/2022 and 1973, n=80) was blindly assessed by three expert pathologists. RESULTS: Median follow-up was 9.6 (95%CI: 8.6-10.2) years. Among 521 patients (73% men, median age 67.0 years), 350 recurred, 57 progressed in stage, 20 developed metastases, and 15 died from BC (median of 9.6 years after diagnosis). Cancer-specific survival probabilities were 0.99, 0.98 and 0.96 at 5-, 10- and 15- years, respectively. Fifty patients who were recurrence-free for the first 5 years developed late recurrences and 2 of them died of BC. Metastatic TaLG had more adverse transcriptomic findings in keeping with higher grade tumors despite phenotypically similar to indolent tumors. Grading concordance for the 2004/2022 system and WHO 1973 was 0.78 (95%CI: 0.65-0.90) and 0.41 (95%CI: 0.32-0.50), respectively. CONCLUSION: This study with long-term data challenges the assumption that primary TaLG NMIBC nearly never progresses to lethal disease if followed long enough. However, the risk of BC-related mortality is extremely low in patients who are recurrence-free for the first 5 years. Minimizing variability in pathological grading remains an unmet need.

Learning curve for fusion magnetic resonance imaging targeted prostate biopsy and three-dimensional transrectal ultrasonography segmentation.

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.

Comparative effectiveness of robot-assisted radical cystectomy with intracorporeal urinary diversion vs open radical cystectomy for bladder cancer.

OBJECTIVES: To assess the comparative effectiveness of robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) vs open radical cystectomy (ORC) for bladder cancer (BC). PATIENTS AND METHODS: We conducted a real-life monocentric study including all consecutive patients who underwent RARC with ICUD or ORC for BC at our institution from 2014 to 2023. Uni- and multivariable logistic and Cox regression analyses were used to compare perioperative, oncological and stricture outcomes between both groups by calculating odds (ORs) and hazard (HRs) ratios with their corresponding 95% confidence intervals (CIs), respectively. RESULTS: Overall, 316 patients underwent either RARC with ICUD (n = 228 [72.2%]) or ORC (n = 88 [27.8%]). The perioperative benefits of RARC vs ORC included decreased risks of major blood loss (OR 0.10, 95% CI 0.04-0.23; P < 0.001), perioperative transfusion (OR 0.30, 95% CI 0.16-0.57; P < 0.001), 90-day major complications (OR 0.56, 95% CI 0.29-0.99; P = 0.04), and prolonged initial length of hospital stay (OR 0.20, 95% CI 0.09-0.35; P < 0.001), as well as more days alive and out of the hospital within 90 days of surgery (OR 2.56, 95% CI 1.46-4.6; P < 0.01). In addition, the use of RARC vs ORC was associated with a higher lymph node (LN) count (OR 3.35, 95% CI 1.83-6.30; P < 0.001), while there was no significant difference in recurrence-free (HR 0.72, 95% CI 0.49-1.07; P = 0.1), cancer-specific (HR 0.69, 95% CI 0.43-1.10; P = 0.1), overall (HR 0.76, 95% CI 0.47-1.20; P = 0.3) and uretero-ileal stricture-free (HR 1.18, 95% CI 0.62-2.25; P = 0.6) survival between both groups after a median (interquartile range) follow-up of 42.3 (16.4-73.8) months. CONCLUSION: Our real-world study supports the effectiveness of RARC with ICUD vs ORC for BC. We generally observed better perioperative outcomes, as well as similar oncological-except for higher LN count-and uretero-ileal stricture outcomes after RARC with ICUD vs ORC.

Adjuvant intravesical therapy in intermediate-risk non-muscle-invasive bladder cancer.

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.

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.

The potential benefits of concomitant statins treatment in patients with non-muscle-invasive bladder cancer.

OBJECTIVE: To investigate the influence of statins on the survival outcomes of patients with non-muscle-invasive bladder cancer (NMIBC) treated with adjuvant intravesical bacille Calmette-Guérin (BCG) immunotherapy. PATIENTS AND METHODS: A retrospective cohort of consecutive patients with NMIBC who received intravesical BCG therapy from 2001 to 2020 and statins prescription were identified. Overall survival (OS), cancer-specific survival (CSS), recurrence-free survival (RFS), and progression-free survival (PFS) were analysed between the Statins Group vs No-Statins Group using Kaplan-Meier method and multivariable Cox regression. RESULTS: A total of 2602 patients with NMIBC who received intravesical BCG were identified. The median follow-up was 11.0 years. On Kaplan-Meier analysis, the Statins Group had significant better OS (P < 0.001), CSS (P < 0.001), and PFS (P < 0.001). Subgroup analysis indicated statins treatment started before BCG treatment had better CSS (P = 0.02) and PFS (P < 0.01). Upon multivariable Cox regression analysis, the 'statins before BCG' group was an independent protective factor for OS (hazard ratio [HR] 0.607, 95% confidence interval [CI] 0.514-0.716), and CSS (HR 0.571, 95% CI 0.376-0.868), but not RFS (HR 0.885, 95% CI 0.736-1.065), and PFS (HR 0.689, 95% CI 0.469-1.013). CONCLUSIONS: Statins treatment appears to offer protective effects on OS and CSS for patients with NMIBC receiving adjuvant intravesical BCG.

Thromboprophylaxis during neoadjuvant chemotherapy for bladder cancer reduces thromboembolism and bleeding.

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.

Patients and general practitioner knowledge and perception of testicular self-examination for cancer.

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 15‒45-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 1.5‒4.1]; 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 1.6‒2.7]; 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 1.3‒2.7], p < 0.01; and OR = 1.6 [95% CI 1.2‒2.1], 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.

Perioperative and functionnal outcomes of robot-assisted laparoscopic versus open ureterovesical reimplantation for benign lower ureteral pathologies: a single-center comparative study.

PURPOSE: The robot-assisted laparoscopic (RALUVR) and open (OUVR) approaches have both been described for ureterovesical reimplantation to treat benign lower ureteral pathologies. Thus, we aimed to compare the perioperative and functional outcomes of RALUVR vs. OUVR. METHODS: We performed a retrospective comparative study including all consecutive patients treated with RALUVR or OUVR for benign lower ureteral pathologies between January 2013 and December 2022 at our center. Logistic regression analyses were used to assess the predictors of complication ≥ Clavien-Dindo (CD) III within 90 days, prolonged length of stay (LOS), and 90-day overall success. The Kaplan-Meier method and Cox regression analyses were used to assess vesicoureteral reflux-free (VU-RFS) and stenosis-free (SFS) survivals. RESULTS: Overall, 44 patients underwent RALUVR (n = 19; 43%) and OUVR (n = 25; 57%). In univariable logistic regression analyses, the use of RALUVR vs. OUVR was not significantly associated with postoperative complications ≥ CDIII (OR = 0.98; 95% CI=[0.17-5.09]; p = 0.98), and 90-day overall success (OR = 1.43; 95% CI=[0.24-11.28]; p = 0.7). Despite a shorter median LOS after RALUVR vs. OUVR (4 vs. 10 days, respectively; p < 0.001), multivariable logistic regression analysis showed no impact of the surgical approach on prolonged LOS (OR = 0.51, 95% CI=[0.03-13.86]; p = 0.65). No significant difference was observed in 2-year VU-RFS (72.9% vs. 100%, respectively; p = 0.2) and 2-year SFS between the RALUVR and OUVR groups (85.7% vs. 87.7%, respectively; p = 0.8). In Cox regression analysis, the use of RALUVR vs. OUVR was not significantly associated with VU-RFS (HR = 4.26; 95% CI=[0.38-47.84]; p = 0.24) or SFS (HR = 1.32; 95% CI=[0.22-8.01]; p = 0.76). CONCLUSION: We observed that RALUVR provides similar perioperative and functional outcomes as compared to OUVR, except for potentially shorter LOS.

Open versus robotic partial nephrectomy in obese patients: a multi-institutional propensity score-matched analysis (UroCCR 43-Robese study).

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.

Differential effect of surgical technique on intravesical recurrence after radical nephroureterectomy in patients with upper tract urothelial cancer: a systematic review and Meta-analysis.

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.

Novel intravesical therapies and delivery systems for the management of bladder cancer.

PURPOSE OF REVIEW: Bladder cancer is a substantial burden for public health worldwide. A risk-adapted treatment strategy is required for non muscle-invasive (NMIBC) and muscle-invasive bladder cancer (MIBC). To date, treatment includes surgery with or without peri-operative local or systemic treatment. The aim of this review was to explore novel intravesical therapies and delivery systems emerging in NMIBC and MIBC. RECENT FINDINGS: Several novel intravesical therapies and delivery systems for NMIBC and MIBC treatment recently emerged. Hyperthermic intravesical chemotherapy (HIVEC) allows a reasonable cancer control in selected high-risk NMIBC. Novel intravesical drugs such as nadofaragene firadenovec, Oncofid-P-B or Nogapendekin alfa-inbakicept seem to be safe and well tolerated. However, their efficacy in high-risk NMIBC should be further investigated. Hydrogels appear to be safe, well tolerated and potentially efficient in primary chemoablation in selected cases of low-grade intermediate-risk NMIBC tumors. Drug-releasing intravesical systems (drug-RIS) such as TAR-200 are safe and well tolerated, providing high partial and complete response rate in both NMIBC and MIBC patients. SUMMARY: The armamentarium for the treatment of bladder cancer patients is expanding, notably with HIVEC, hydrogels, drug-RIS and novel therapies. However, accurate patients' selection is key to prevent disease progression in any bladder-sparing strategy, and radical cystectomy remains the gold-standard to date.

Health-related quality of life of patients with prostate cancer initiating GnRH agonist therapy: the PRISME study.

OBJECTIVES: To compare the evolution of health-related quality of life (HRQoL) over 6 months of GnRH agonist (GnRHa) therapy among age groups for patients with prostate cancer (PCa). PATIENTS AND METHODS: PRISME (NCT03516110) was a non-interventional, prospective study conducted in France in patients aged ≥60 years with PCa initiating GnRHa therapy within routine care. HRQoL was evaluated at baseline and after 6 months using the EORTC quality of life in ELDerly cancer patients 14 items (QLQ-ELD14) questionnaire. Cognitive status was assessed using the Mini Mental State Examination (MMSE). Analyses of covariance compared the evolution of the change from baseline of the QLQ-ELD14 scores among age groups. RESULTS: 814 patients were enrolled (245, 60-70 years; 314, 70-75 years; 252, ≥75 years). Slight or no changes were observed in each QLQ-ELD14 dimension between baseline and 6 months, overall and by age. In the primary effectiveness analysis, there was no difference among age groups in the change from baseline in QLQ-ELD14 scores. Baseline cognitive status was lower in the oldest age group, but there were no changes in all age groups. As expected, sexual function declined in all age groups. CONCLUSION: GnRHa therapy influence on HRQoL, cognition and sexuality appeared independent of age.

Prostate cancer that has spread to other parts of the body is called "advanced prostate cancer." Hormone therapy is a common treatment for high risk localized and advanced prostate cancer. It works by lowering hormone levels, causing prostate cancers to grow more slowly or shrink. But, side effects from this kind of treatment can affect a patient's quality of life. Common side effects of hormone therapy include a loss of sex drive, erectile dysfunction, bone weakening, hot flushes, or mood disorders. Most patients with prostate cancer are over the age of 60 years, but elderly patients are often excluded from clinical trials, meaning that we lack data about them. This study assessed if there was a link between age and health-related quality of life in men with advanced prostate cancer treated with hormone therapy. The study included 814 men with advanced prostate cancer who were over 60 years old and had started a type of hormone therapy called gonadotropin-releasing hormone agonist (GnRHa) therapy. The results showed that health-related quality of life was similar after 6 months of hormone therapy, in the overall group of patients and in the different age groups (60­70, 70­75, and over 75 years of age). Cognitive impairment occurred about twice as often in patients aged over 75 years than among younger patients, before initiation of hormone therapy. Cognitive impairment was likely caused by ageing and was not associated with hormone therapy treatment. Sexual function decreased in all age groups, particularly in patients aged 60­70 years. This study did not reveal any major impact of hormone therapy on health-related quality of life in older men with advanced prostate cancer, after a 6-month period and the use of routine questionnaires.

Renal involvement in genetic neurocutaneous syndromes.

Phakomatoses, otherwise known as neurocutaneous syndromes, are a heterogeneous group of rare genetic disorders that predominantly affect structures arising from the embryonic ectoderm, namely the skin, eye globe, retina, and central nervous system. In addition to the common neurocutaneous syndromes (neurofibromatosis, tuberous sclerosis complex, Sturge Weber syndrome, Von Hippel-Lindau syndrome), a large number of relatively uncommon phakomatoses have been described in the literature. Cardiovascular, pulmonary, and musculoskeletal systems involvement in these disorders have been reported. Data on kidney involvement is not well described. This review discusses renal involvement in neurocutaneous syndromes. This includes the association with renal masses (cyst, angiomyolipoma, benign or malignant tumor), known vasculopathy, glomerular or tubular disorders, urinary tract anomalies, hypertension, and chronic kidney disease.

Role of Antimuscarinics Combined With Alpha-blockers in the Management of Urinary Storage Symptoms in Patients With Benign Prostatic Hyperplasia: An Updated Systematic Review and Meta-analysis.

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.

Diagnostic Accuracy of Clinical Lymph Node Staging for Upper Tract Urothelial Cancer Patients: A Multicenter, Retrospective, Observational Study.

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.

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.

Nephrectomy for kidney tumour increases the risk of de novo arterial hypertension.

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.
