RESUMO
PURPOSE OF REVIEW: Several novel therapies approved by the Food and Drug Administration (FDA) and explosion of clinical trials have changed the landscape Bacillus Calmette-Guérin (BCG)-unresponsive nonmuscle invasive bladder cancer (NMIBC). Given the recent advancements in bladder sparing options, the role of radical cystectomy (RC) in BCG-unresponsive NMIBC remains a subject of debate. RECENT FINDINGS: All three novel agents currently approved by the FDA for BCG-unresponsive NMIBC have strict indication [carcinoma in situ (CIS)], low response rate, and short response duration. Some promising new agents are awaiting results and/or FDA approval. RC still provides the best oncologic control and acceptable quality of life, and potentially represents the most cost-effective option. SUMMARY: It is an exciting time for the urologic oncology community to see the FDA approvals of some of the novel bladder sparing therapies and expansion of ongoing clinical trials. Yet, RC should still be considered as the gold standard of BCG-unresponsive NMIBC. We also must be cautious and selective in recommending bladder sparing options for patients with BCG-unresponsive NMIBC.
RESUMO
PURPOSE: To report perioperative and long-term postoperative outcomes of cystectomy patients with ileal conduit (IC) urinary diversion undergoing parastomal hernia (PSH) repair. METHOD: We reviewed patients who underwent cystectomy and IC diversion between 2003 and 2022 in our center. Baseline variables, including surgical approach of PSH repair and repair technique, were captured. Multivariable Cox regressionanalysis was performed to test for the associations between different variables and PSH recurrence. RESULTS: Thirty-six patients with a median (IQR) age of 79 (73-82) years were included. The median time between cystectomy and PSH repair was 30 (14-49) months. Most PSH repairs (32/36, 89%) were performed electively, while 4 were due to small bowel obstruction. Hernia repairs were performed through open (n=25), robotic (10), and laparoscopic approaches (1). Surgical techniques included direct repair with mesh (20), direct repair without mesh (4), stoma relocation with mesh (5), and stomarelocation without mesh (7). The 90-day complication rate was 28%. In a median follow-up of 24 (7-47) months, 17 patients (47%) had a recurrence. The median time to recurrence was 9 (7-24) months. On multivariable analysis, 90-day complication following PSH repair was associated with an increased risk of recurrence. CONCLUSIONS: In this report of one of the largest series of PSH repair in the Urology literature, 47% of patients had a recurrence following hernia repair with a median follow-up time of 2 years. There was no significant difference in recurrence rates when comparing repair technique or the use of open or minimally invasive approaches.

INTRODUCTION: Opioid dependence represents a public health crisis and can be observed after outpatient urologic procedures. The purpose of this study was to evaluate the risk of persistent opioid usage after radical orchiectomy for testicular cancer. MATERIALS AND METHODS: The TriNetX Research network database was queried for men between 15 and 45 years undergoing radical orchiectomy for a diagnosis of testicular cancer. All patients with N+ or M+ disease, prior opioid use, and patients who underwent chemotherapy, radiotherapy, or retroperitoneal lymph node dissection were excluded. Patients were stratified whether they were prescribed opioids or not at time of orchiectomy. The incidence of new, persistent opioid use, defined as a prescription for opioids between 3 and 15 months after orchiectomy, was evaluated. RESULTS: A total of 2,911 men underwent radical orchiectomy for testicular cancer, of which 89.8% were prescribed opioids at time of orchiectomy. After propensity score matching for age, race, and history of psychiatric diagnosis, 592 patients were included (296 received opioids, 296 did not). Overall, 0% of patients who did not receive postoperative opioids developed new persistent opioid use, whereas 10.5% of patients who received postoperative opioids developed new persistent opioid use. Patients prescribed postoperative opioids for orchiectomy had statistically higher risk difference of developing new persistent opioid use (Risk Difference: 10.5%; 95% CI: 7.0-14.0; Z: 5.7; P < 0.01). CONCLUSIONS: Postoperative opioid prescription following radical orchiectomy is significantly associated with developing new persistent opioid use, with 1 in 10 young men who received postoperative opioids obtaining a new prescription for opioids well beyond the postoperative period. Future efforts should emphasize nonopioid pathways for pain control following this generally minor procedure.
RESUMO
We previously reported that tumors harboring any one of four gene mutations (ATM, RB1, FANCC, or ERCC2) were likely to respond to neoadjuvant cisplatin-based chemotherapy (NAC), resulting in cancer-free surgical specimens at the time of cystectomy (pT0). Here, we report our validation of this finding. Using the CARIS 592 Gene Panel (Caris Life Sciences, Phoenix, AZ, USA), we analyzed 105 pre-NAC tumor specimens from a large multicenter trial (S1314) of either neoadjuvant gemcitabine and cisplatin (GC), or dose-dense methotrexate, vinblastine, Adriamycin, and cisplatin (DDMVAC). We found that a mutation in any one of these four genes predicted for pT0 at surgery (odds ratio = 5.36; 95% confidence interval [CI] 2.05, 14.02; two-sided p = 0.0006). The biomarker was better at predicting the presence of disease (negative predictive value for pT0 86%; 95% CI 73%, 94%) than the absence of disease (positive predictive value for pT0 48%; 95% CI 35%, 62%). There was no evidence of an interaction between the treatment arm (DDMVAC vs GC) and the genetic variant in terms of pT0. When combined with clinical assessment, these findings help inform patient selection for bladder preservation after cisplatin-based chemotherapy. PATIENT SUMMARY: A common standard of care for patients with muscle-invasive bladder cancer is neoadjuvant chemotherapy (NAC) followed by cystectomy to achieve cure. We previously discovered that specific DNA mutations in tumor samples collected at initial biopsy (transurethral resection of a bladder tumor) were predictive of a complete response to NAC. In other words, patients with these mutations were more likely to have a bladder found to be cancer free after surgery. In this study, we analyzed a larger set of tumor samples from a national clinical trial of chemotherapy followed by cystectomy to validate these earlier findings. We conclude that this biomarker test, when combined with careful clinical assessment, can be used to allocate patients to careful bladder surveillance instead of surgery. This hypothesis has been tested in the RETAIN trial presented previously (NCT02710734).
RESUMO
BACKGROUND AND OBJECTIVE: Therapeutic options for patients with non-muscle-invasive bladder cancer (NMIBC) have traditionally been limited to intravesical immunotherapy or chemotherapy. A considerable number of new options have been investigated in recent years. Our aim was to review the efficacy and toxicity of novel therapeutic options (results already reported or currently under investigation) for patients with NMIBC. METHODS: We assessed the efficacy of various novel therapeutic options by examining key endpoints in diverse settings, including recurrence, progression, overall survival, disease-specific survival, and complete response. We identified the principal advantages and limitations for each option. Safety was predominantly evaluated as the incidence of grade ≥3 adverse events. Our investigation focused on evidence from scientific articles and congress abstracts published in English within the past 5 yr. KEY FINDINGS AND LIMITATIONS: To date, pembrolizumab, nadofaragene firadenovec, and the combination of BCG with N-803 have received US Food and Drug administration approval for the treatment of BCG-unresponsive carcinoma in situ of the bladder (with or without papillary tumours). Five phase 3 trials are recruiting BCG-naïve patients with high-risk NMIBC. There is increasing interest in an ablative rather than an adjuvant approach for patients with intermediate-risk NMIBC. CONCLUSIONS AND CLINICAL IMPLICATIONS: Novel drugs and device-assisted drug delivery systems are on the verge of changing the treatment of NMIBC. Novel intravesical options seem to have the same efficacy with fewer adverse events in comparison to systemic therapies. PATIENT SUMMARY: We reviewed new therapy options for non-muscle-invasive bladder cancer. Two agents (pembrolizumab and nadofaragene firadenovec) have been approved to date. Ongoing trials are assessing direct delivery of drugs in solution into the bladder. This route seems to have similar efficacy and fewer side effects than intravenous immunotherapy.
RESUMO
The contemporary paradigm of testicular cancer management is achieving high and durable cure rates while minimizing the burden of treatment given the potential long-term toxicities associated with radiation therapy and systemic therapies. The management of low-stage seminoma has seen significant changes in recent years. Nuances of surveillance strategies for stage I seminoma exist and continue to evolve. Emerging data show retroperitoneal lymph node dissection is a viable treatment option for selected patients with clinical stage IIA and IIB seminoma.

OBJECTIVE: To compare survival and pathologic outcomes in patients with progressive muscle-invasive bladder cancer (pgMIBC) and de novo muscle-invasive bladder cancer (dnMIBC) after radical cystectomy (RC), with a focus on the role of neoadjuvant chemotherapy (NAC). METHODS: A comprehensive literature search was conducted on PubMed and EMBASE databases to identify studies comparing pgMIBC to dnMIBC. Survival outcomes, including cancer-specific survival (CSS), overall survival (OS), and recurrence-free survival (RFS), and pathologic outcomes (rates of ≤pT1, pT0, pT3/T4, and pN+ disease) were compared between pgMIBC and dnMIBC. RESULTS: The analysis included 19 cohorts from 16 studies, categorized into 3 groups based on NAC use: 1. patients who underwent RC and were all treated with NAC (RCâ¯+â¯NAC only group); 2. patients who underwent RC, with or without NAC (RC +/- NAC group); 3. patients who only underwent RC without NAC (RC only group). Compared to dnMIBC, pgMIBC demonstrated worse outcomes for CSS, OS, and RFS. In the RCâ¯+â¯NAC only group (3 cohorts), the hazard ratio (HR) for CSS was 1.52 (95% confidence interval [CI]â¯=â¯1.05-2.2), while the HR for OS was 1.46 (95%CIâ¯=â¯1.05-2.02). Similarly, in the RC +/- NAC group (6 cohorts for CSS and 3 cohorts for OS), the HR for CSS was 1.27 (95%CIâ¯=â¯1.05-1.55), and the HR for OS was 1.27 (95%CIâ¯=â¯1.08-1.51). There were no significant differences observed in pathologic outcomes, including rates of ≤pT1, pT0, and pT3/T4 disease, across all subgroups. However, pgMIBC was associated with a higher risk of nodal metastatic (pN+) disease in the RCâ¯+â¯NAC only group (4 cohorts, relative risk [RR]â¯=â¯1.43, 95%CIâ¯=â¯1.12-1.84). CONCLUSIONS: The findings highlight the potentially worse prognosis in patients with pgMIBC compared to dnMIBC, even with the modern use of NAC. The study emphasizes the importance of careful patient counseling, further classification of patients for treatment selection, and the consideration of additional or innovative systemic therapies for pgMIBC.

PURPOSE: AUA guidelines for patients with microhematuria (≥3 red blood cells [RBC]/high-power field [hpf]) include cystoscopy for most over age 40 due to risk of urothelial cancer (UC). Cxbladder Triage (CxbT) is a urinary genomic test with UC negative predictive value of 99%. In this prospective randomized controlled trial, we compared cystoscopy use in a standard of care (SOC) arm vs a marker-based approach. MATERIALS AND METHODS: All patients with hematuria provided urine for a CxbT. Those categorized as lower risk (LR), defined as 3 to 29 RBC/hpf and minimal smoking history (<10 pack-years) were randomized between the test group provided with the CxbT result vs the SOC control group. Negative CxbT patients were offered omission of cystoscopy with surveillance. "Not lower risk" (NLR) patients (>30 RBC/hpf or >10 pack-year smoking history) had a CxbT but otherwise SOC. Patient decision and outcomes were recorded. RESULTS: Of 390 eligible patients, 255 were NLR and 135 were LR randomized to CxbT informed decision or SOC. The median age was 62 years (range 18-94) and 54% were male. Overall, 63% of CxbT tests were negative. For NLR patients, 82% had cystoscopy. In the LR control group, cystoscopy was performed in 67% of SOC and 27% in the test group (relative risk 0.41 [95% CI 0.27-0.61]). Compared to cystoscopy, CxbT had 90% sensitivity, 56% specificity, and 99% negative predictive value for UC. CONCLUSIONS: In this prospective randomized controlled trial, use of CxbT in patients with LR hematuria resulted in 59% reduction of cystoscopy use. This clinical utility of CxbT can reduce the burden of unnecessary cystoscopies.

OBJECTIVE: To compare the value of flexible blue-light cystoscopy (BLC) vs flexible white-light cystoscopy (WLC) in the surveillance setting of non-muscle-invasive bladder cancer (NMIBC). METHODS: All major databases were searched for articles published before May 2023 according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. The primary outcome was the accuracy of flexible BLC vs WLC in detecting bladder cancer recurrence among suspicious bladder lesions. RESULTS: A total of 10 articles, comprising 1634 patients, were deemed eligible for the quantitative synthesis. In the meta-analysis focusing on the detection of disease recurrence, there was no difference between flexible BLC and WLC (odds ratio [OR] 1.08, 95% confidence interval [CI] 0.82-1.41)]; the risk difference (RD) showed 1% of flexible BLC, corresponding to a number needed to treat (NNT) of 100. In the subgroup meta-analysis of detection of carcinoma in situ (CIS) only, there was again no significant difference between flexible BLC and WLC (OR 1.19, 95% CI 0.82-1.69), BLC was associated with a RD of 2% (NNT = 50). The positive predictive values for flexible BLC and WLC in detecting all types of recurrence were 72% and 66%, respectively, and for CIS they were 39% and 29%, respectively. CONCLUSION: Surveillance of NMIBC with flexible BLC could detect more suspicious lesions and consequently more tumour recurrences compared to flexible WLC, with a increase in the rate of false positives leading to overtreatment. A total of 100 and 50 flexible BLC procedures would need to be performed to find on additional tumor and CIS recurences, respectively. A risk-stratified strategy for patient selection could be considered when using flexible BLC for the surveillance of NMIBC patients.
RESUMO
The use of blue light cystoscopy (BLC) has been shown to improve bladder tumor detection. However, data demonstrating the efficacy of BLC across different races are limited. Herein, we aim to evaluate heterogeneity in the characteristics of BLC for the detection of malignant lesions among various races. Clinicopathologic information was collected from patients enrolled in the multi-institutional Cysview® registry (2014-2021) who underwent transurethral resection or biopsy of bladder tumors. Outcome variables included sensitivity and negative and positive predictive values of BLC and white light cystoscopy (WLC) for the detection of malignant lesions among various races. Overall, 2379 separate lesions/tumors were identified from 1292 patients, of whom 1095 (85%) were Caucasian, 96 (7%) were African American, 51 (4%) were Asian, and 50 (4%) were Hispanic. The sensitivity of BLC was higher than that of WLC in the total cohort, as well as in the Caucasian and Asian subgroups. The addition of BLC to WLC increased the detection rate by 10% for any malignant lesion in the total cohort, with the greatest increase in Asian patients (18%). Additionally, the positive predictive value of BLC was highest in Asian patients (94%), while Hispanic patients had the highest negative predictive value (86%). Our study showed that regardless of race, BLC increases the detection of bladder cancer when combined with WLC.
RESUMO
PURPOSE: We assessed the effect of prophylactic biologic mesh on parastomal hernia (PSH) development in patients undergoing cystectomy and ileal conduit (IC). MATERIALS AND METHODS: This phase 3, randomized, controlled trial (NCT02439060) included 146 patients who underwent cystectomy and IC at the University of Southern California between 2015 and 2021. Follow-ups were physical exam and CT every 4 to 6 months up to 2 years. Patients were randomized 1:1 to receive FlexHD prophylactic biological mesh using sublay intraperitoneal technique vs standard IC. The primary end point was time to radiological PSH, and secondary outcomes included clinical PSH with/without surgical intervention and mesh-related complications. RESULTS: The 2 arms were similar in terms of baseline clinical features. All surgeries and mesh placements were performed without any intraoperative complications. Median operative time was 31 minutes longer in patients who received mesh, yet with no statistically significant difference (363 vs 332 minutes, P = .16). With a median follow-up of 24 months, radiological and clinical PSHs were detected in 37 (18 mesh recipients vs 19 controls) and 16 (8 subjects in both arms) patients, with a median time to radiological and clinical PSH of 8.3 and 15.5 months, respectively. No definite mesh-related adverse events were reported. Five patients (3 in the mesh and 2 in the control arm) required surgical PSH repair. Radiological PSH-free survival rates in the mesh and control groups were 74% vs 75% at 1 year and 69% vs 62% at 2 years. CONCLUSIONS: Implementation of biologic mesh at the time of IC construction is safe without significant protective effects within 2 years following surgery.

INTRODUCTION: Limited data are available regarding the effect of enhanced recovery after surgery (ERAS) protocols on the long-term outcomes of radical cystectomy (RC) in bladder cancer patients. The aim of this study is to evaluate the oncological outcomes in patients who underwent RC with ERAS protocol. METHODS: We reviewed the records of patients who underwent RC for primary urothelial bladder carcinoma with curative intent from January 2003 to August 2022. The primary and secondary outcomes were recurrence-free (RFS) and overall survival (OS). Multivariable Cox regression analysis was performed to evaluate the effect of ERAS on oncological outcomes. RESULTS: A total of 967 ERAS patients and 1144 non-ERAS patients were included in this study. The RFS rates at 1, 3, and 5 years after RC were 81%, 71.5%, and 69% in the ERAS cohort, respectively. This rate in the non-ERAS group was 81%, 71%, and 67% at 1, 3, and 5 years after RC, respectively (P = 0.50). However, ERAS patients had significantly better OS with 86%, 73%, and 67% survival rates at 1, 3, and 5 years compared to 84%, 68%, and 59.5% survival rates in the non-ERAS group, respectively (P = 0.002). In multivariable analysis adjusting for other relevant factors, ERAS was no longer independently associated with recurrence-free (HR = 0.96, 95% CI 0.76-1.22, P = 0.75) or overall survival (HR = 0.84, 95% CI 0.66-1.09, P = 0.28) following RC. CONCLUSION: ERAS protocols are associated with a shorter hospital stay, yet with no impact on long-term oncologic outcomes in patients undergoing RC for bladder cancer.

OBJECTIVES: To assess the efficacy of blood-based liquid biopsy in the diagnosis, surveillance, and prognosis of upper tract urothelial carcinoma (UTUC). METHODS AND MATERIALS: In this prospective study, peripheral blood samples were collected from patients with primary UTUC before surgery with curative intent and follow-up visits at University of Southern California between May 2021 and September 2022. The samples were analyzed using the third-generation comprehensive high-definition single-cell assay (HDSCA3.0) to detect rare events, including circulating tumor cells (CTCs) and oncosomes, based on the immunofluorescence signals of DAPI (D), cytokeratin (CK), CD45/CD31 (CD), and vimentin (V). The findings of pre-surgery liquid biopsies were compared with those of blood samples from normal donors (NDs) and matched follow-up liquid biopsies. The association between liquid biopsy findings and clinical data, including recurrence-free survival (RFS), was also assessed. RESULTS: Twenty-eight patients with UTUC were included, of whom 21 had follow-up samples. Significant differences in specific rare analytes were detected in the preoperative samples compared to the NDs. In the post- vs. presurgery matched analysis, a significant decrease was detected in total-, CK-, and CK|V oncosomes, as well as in D-, D|V-, and D|V|CD cells. With a median follow-up of 11 months, 8 patients had disease recurrence. Survival analysis demonstrated that patients with >1.95 preoperative CK|V oncosomes (pâ¯=â¯0.020) and those with >4.18 D|CK|V cells (pâ¯=â¯0.050) had worse RFS compared to other patients. CONCLUSIONS: This study demonstrated promising initial evidence for the biomarker role of CTCs and oncosomes in the diagnosis and surveillance of patients with UTUC.

PURPOSE: The purpose of this American Urological Association (AUA) guideline amendment is to provide a useful reference on the effective evidence-based treatment strategies for early-stage testicular cancer. METHODOLOGY/METHODS: The original methodology protocol included searches of PubMed®, Embase®, and the Cochrane Central Register of Controlled Trials (CENTRAL) from January 1980 through August 2018. The search strategy used medical subject heading (MeSH) terms and key words relevant to the diagnosis and treatment of early-stage testicular cancer. The searches conducted for the update presented herein utilized the same methodological protocol to capture literature published through March 2023. When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided as Clinical Principles and Expert Opinions. RESULTS: Updates were made to statements on imaging, seminoma management, non-seminoma management, surveillance for stage I testicular cancer, and additional survivorship. Further revisions were made to the methodology and reference sections as appropriate. CONCLUSIONS: This guideline seeks to improve clinicians' ability to evaluate and treat patients with early-stage testicular cancer based on currently available evidence. Future studies will be essential to further support or refine these statements to improve patient care.
