"Prostatectomy after gender-affirming vaginoplasty for a transgender woman with prostate cancer".

We present the case of a 75 year old transgender woman 18 months post gender-affirming vaginoplasty found to have unfavorable, intermediate risk prostate cancer. She elected a robotic radical prostatectomy with bilateral pelvic lymph node dissection. Postoperatively, the patient resumed neovaginal dilation without difficulty, and had improvements on International Prostate Symptom Score when compared to post-vaginoplasty, pre-prostatectomy. Incontinence measured by Revised Urinary Incontinence Scale remained mild. Robotic prostatectomy can, under appropriate circumstances, allow preservation of the neovaginal vault, but requires considerable experience and multidisciplinary intraoperative collaboration.

Transperineal vs Transrectal Prostate Biopsy-The PREVENT Randomized Clinical Trial.

This randomized clinical trial compares the effect of transperineal vs transrectal prostate biopsy on infection rates after biopsy.

Integrative Drug Screening and Multiomic Characterization of Patient-derived Bladder Cancer Organoids Reveal Novel Molecular Correlates of Gemcitabine Response.

BACKGROUND AND OBJECTIVE: Predicting response to therapy for each patient's tumor is critical to improving long-term outcomes for muscle-invasive bladder cancer. This study aims to establish ex vivo bladder cancer patient-derived organoid (PDO) models that are representative of patients' tumors and determine the potential efficacy of standard of care and curated experimental therapies. METHODS: Tumor material was collected prospectively from consented bladder cancer patients to generate short-term PDO models, which were screened against a panel of clinically relevant drugs in ex vivo three-dimensional culture. Multiomic profiling was utilized to validate the PDO models, establish the molecular characteristics of each tumor, and identify potential biomarkers of drug response. Gene expression (GEX) patterns between paired primary tissue and PDO samples were assessed using Spearman's rank correlation coefficients. Molecular correlates of therapy response were identified using Pearson correlation coefficients and Kruskal-Wallis tests with Dunn's post hoc pairwise comparison testing. KEY FINDINGS AND LIMITATIONS: A total of 106 tumors were collected from 97 patients, with 65 samples yielding sufficient material for complete multiomic molecular characterization and PDO screening with six to 32 drugs/combinations. Short-term PDOs faithfully represent the tumor molecular characteristics, maintain diverse cell types, and avoid shifts in GEX-based subtyping that accompany long-term PDO cultures. Utilizing an integrative approach, novel correlations between ex vivo drug responses and genomic alterations, GEX, and protein expression were identified, including a multiomic signature of gemcitabine response. The positive predictive value of ex vivo drug responses and the novel multiomic gemcitabine response signature need to be validated in future studies. CONCLUSIONS AND CLINICAL IMPLICATIONS: Short-term PDO cultures retain the molecular characteristics of tumor tissue and avoid shifts in expression-based subtyping that have plagued long-term cultures. Integration of multiomic profiling and ex vivo drug screening data identifies potential predictive biomarkers, including a novel signature of gemcitabine response. PATIENT SUMMARY: Better models are needed to predict patient response to therapy in bladder cancer. We developed a platform that uses short-term culture to best mimic each patient's tumor and assess potential sensitivity to therapeutics.

Extragonadal germ cell tumors: A clinicopathologic study with emphasis on molecular features, clinical outcomes and associated secondary malignancies.

Extragonadal germ cell tumors (EGCTs) are rare, representing <5% of all germ cell tumors (GCTs). Whilst EGCTs share morphological and immunohistochemical features with their gonadal counterparts, they tend to be more aggressive and are frequently associated with secondary somatic malignancies. The aim of our study was to evaluate the clinical, morphological and immunohistochemical features, and to analyze tumors for chromosomal abnormalities of 12p, in addition to any novel genetic alterations, in a series of EGCTs. Seventy-seven EGCTs were included. Anterior mediastinum was the most common anatomic site, followed by central nervous system, retroperitoneum, sacroccygeal area, and neck. Whole genome SNP array identified isochromosome 12p in 26% of tumors. Additional cytogenetic abnormalities included the presence of gain of chr 21 in 37% of tumors. Somatic-type malignancies were identified in 8% of patients. Disease progression (metastasis and/or recurrence) was documented in 8 patients, most of whom died from their relapse. Three patients who died of disease had somatic-type malignancies. Mediastinal seminomas had a significantly better overall survival when compared to mediastinal non-seminomatous GCTs. Our study demonstrates that EGCTs share similar histologic features, but diverse clinical outcomes compared to their gonadal counterparts. Outcomes vary according to anatomic location and histologic subtypes. Our data corroborate that somatic-type malignancies are frequently encountered in mediastinal EGCTs and that their presence portends a poorer prognosis.

NCCN Guidelines® Insights: Bladder Cancer, Version 3.2024.

Bladder cancer, the sixth most common cancer in the United States, is most commonly of the urothelial carcinoma histologic subtype. The clinical spectrum of bladder cancer is divided into 3 categories that differ in prognosis, management, and therapeutic aims: (1) non-muscle-invasive bladder cancer (NMIBC); (2) muscle invasive, nonmetastatic disease; and (3) metastatic bladder cancer. These NCCN Guidelines Insights detail recent updates to the NCCN Guidelines for Bladder Cancer, including changes in the fifth edition of the WHO Classification of Tumours: Urinary and Male Genital Tumours and how the NCCN Guidelines aligned with these updates; new and emerging treatment options for bacillus Calmette-Guérin (BCG)-unresponsive NMIBC; and updates to systemic therapy recommendations for advanced or metastatic disease.

Social Vulnerability and Receipt of Neoadjuvant Chemotherapy in Patients Undergoing Radical Cystectomy for Bladder Cancer.

OBJECTIVE: To evaluate the association between a population-level measure of social determinants of health, the Centers for Disease Control and Prevention Social Vulnerability Index (SVI), and receipt of neoadjuvant chemotherapy in patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy. METHODS: We queried our institutional database for patients with nonmetastatic MIBC treated with radical cystectomy between 2000 and 2022. Patients were assigned an SVI via ZIP code of residence and grouped into quintiles of SVI (ie, least vulnerable to most vulnerable). Multivariable logistic regression was performed to evaluate the association between SVI and receipt of neoadjuvant chemotherapy, adjusting for age, race, gender, and cancer stage. A sub-analysis was performed to evaluate the association between subthemes of SVI (socioeconomic status, household composition/disability, race/ethnicity/language, and housing/transportation) and receipt of neoadjuvant chemotherapy. RESULTS: Of the 978 patients identified, 490 (50.1%) received neoadjuvant chemotherapy. Patients that received neoadjuvant chemotherapy had a lower SVI, were younger, and had >cT2 stage (all, P <.05). The most vulnerable patients had lower odds of receiving neoadjuvant chemotherapy (OR 0.61, 0.39-0.95) compared to the least vulnerable patients. Analysis of subthemes of SVI demonstrated similar associations by socioeconomic status (OR 0.56, 0.36-0.86) and household composition/disability (OR 0.57, 0.33-0.99). CONCLUSION: Adverse social determinants of health, or social vulnerability, are associated with suboptimal and disparate utilization of neoadjuvant chemotherapy in patients with MIBC undergoing radical cystectomy. Strategies for identifying vulnerable populations may allow for more targeted interventions that would improve equity in bladder cancer care.

Efficacy of Intravesical Nadofaragene Firadenovec for Patients With Bacillus Calmette-Guérin-Unresponsive Nonmuscle-Invasive Bladder Cancer: 5-Year Follow-Up From a Phase 3 Trial.

PURPOSE: Nadofaragene firadenovec-vncg is a nonreplicating adenoviral vector-based gene therapy for bacillus Calmette-Guérin (BCG)-unresponsive carcinoma in situ (CIS) with/without high-grade Ta/T1. We report outcomes following 5 years of planned follow-up. MATERIALS AND METHODS: This open-label phase 3 trial (NCT02773849) enrolled patients with BCG-unresponsive nonmuscle-invasive bladder cancer in 2 cohorts: CIS ± Ta/T1 (CIS; n = 107) and Ta/T1 without CIS (Ta/T1 cohort; n = 50). Patients received 75 mL (3 × 1011 vp/mL) nadofaragene firadenovec intravesically once every 3 months with cystoscopy and cytology assessments, with continued treatment offered to those remaining high grade recurrence-free (HGRF). RESULTS: One hundred fifty-seven patients were enrolled from 33 US sites (n = 151 included in efficacy analyses). Median follow-up was 50.8 months (interquartile range 39.1-60.0), with 27% receiving ≥ 5 instillations and 7.6% receiving treatment for ≥ 57 months. Of patients with CIS 5.8% (95% CI 2.2-12.2) were HGRF at month 57, and 15% (95% CI 6.1-27.8) of patients with high-grade Ta/T1 were HGRF at month 57. Kaplan-Meier-estimated HGRF survival at 57 months was 13% (95% CI 6.9-21.5) and 33% (95% CI 19.5-46.6) in the CIS and Ta/T1 cohorts, respectively. Cystectomy-free survival at month 60 was 49% (95% CI 40.0-57.1): 43% (95% CI 32.2-53.7) in the CIS cohort and 59% (95% CI 43.1-71.4) in the Ta/T1 cohort. Overall survival at 60 months was 80% (71.0, 86.0): 76% (64.6-84.5) and 86% (70.9-93.5) in the CIS and Ta/T1 cohorts, respectively. Only 5 patients (4 with CIS and 1 with Ta/T1) experienced clinical progression to muscle-invasive disease. CONCLUSIONS: At 60 months, nadofaragene firadenovec-vncg allowed bladder preservation in nearly half of the patients and proved to be a safe option for BCG-unresponsive nonmuscle-invasive bladder cancer.

Transperineal Versus Transrectal Magnetic Resonance Imaging-targeted and Systematic Prostate Biopsy to Prevent Infectious Complications: The PREVENT Randomized Trial.

BACKGROUND AND OBJECTIVE: The transrectal biopsy approach is traditionally used to detect prostate cancer. An alternative transperineal approach is historically performed under general anesthesia, but recent advances enable transperineal biopsy to be performed under local anesthesia. We sought to compare infectious complications of transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis. METHODS: We assigned biopsy-naïve participants to undergo transperineal biopsy without antibiotic prophylaxis versus transrectal biopsy with targeted prophylaxis (rectal culture screening for fluoroquinolone-resistant bacteria and antibiotic targeting to culture and sensitivity results) through a multicenter, randomized trial. The primary outcome was post-biopsy infection captured by a prospective medical review and patient report on a 7-d survey. The secondary outcomes included cancer detection, noninfectious complications, and a numerical rating scale (0-10) for biopsy-related pain and discomfort during and 7-d after biopsy. KEY FINDINGS AND LIMITATIONS: A total of 658 participants were randomized, with zero transperineal versus four (1.4%) transrectal biopsy infections (difference -1.4%; 95% confidence interval [CI] -3.2%, 0.3%; p = 0.059). The rates of other complications were very low and similar. Importantly, detection of clinically significant cancer was similar (53% transperineal vs 50% transrectal, adjusted difference 2.0%; 95% CI -6.0, 10). Participants in the transperineal arm experienced worse periprocedural pain (0.6 adjusted difference [0-10 scale], 95% CI 0.2, 0.9), but the effect was small and resolved by 7-d. CONCLUSIONS AND CLINICAL IMPLICATIONS: Office-based transperineal biopsy is tolerable, does not compromise cancer detection, and did not result in infectious complications. Transrectal biopsy with targeted prophylaxis achieved similar infection rates, but requires rectal cultures and careful attention to antibiotic selection and administration. Consideration of these factors and antibiotic stewardship should guide clinical decision-making. PATIENT SUMMARY: In this multicenter randomized trial, we compare prostate biopsy infectious complications for the transperineal versus transrectal approach. The absence of infectious complications with transperineal biopsy without the use of preventative antibiotics is noteworthy, but not significantly different from transrectal biopsy with targeted antibiotic prophylaxis.

Interruptions in bladder cancer care during the COVID-19 public health emergency.

BACKGROUND: Academic and community urology centers participating in a pragmatic clinical trial in non-muscle-invasive bladder cancer completed monthly surveys assessing restrictions in aspects of bladder cancer care due to the COVID-19 Public Health Emergency. Our objective was to describe pandemic-related restrictions on bladder cancer care. METHODS: We invited 32 sites participating in a multicenter pragmatic bladder cancer trial to complete monthly surveys distributed through REDCap beginning in May 2020. These surveys queried sites on whether they were experiencing restrictions in the use of elective surgery, transurethral resection of bladder tumors (TURBT), radical cystectomy, office cystoscopy, and intravesical bacillus Calmette-Guerin (BCG) availability. Responses were collated with descriptive statistics. RESULTS: Of 32 eligible sites, 21 sites had at least a 50% monthly response rate over the study period and were included in the analysis. Elective surgery was paused at 76% of sites in May 2020, 48% of sites in January 2021, and 52% of sites in January 2022. Over those same periods, coinciding with COVID-19 incidence waves, TURBT was restricted at 10%, 14%, and 14% of sites, respectively, radical cystectomy was restricted at 10%, 14%, and 19% of sites, respectively, and cystoscopy was restricted at 33%, 0%, and 10% of sites, respectively. CONCLUSIONS: Bladder cancer care was minimally restricted compared with more pronounced restrictions seen in general elective surgeries during the COVID-19 pandemic.

Everything or Nothing: Supervised High-intensity Exercise is the Only Way to Achieve Meaningful Results.

Prehabilitation exercise should be performed via supervised, high-intensity exercise training regimens. This type of training is preferred by patients, increases exercise accountability, leads to emotional and social benefits, and ensures that exercises are performed in a safe and efficient manner.

The effect of cisplatin-based neoadjuvant chemotherapy on the renal function of patients undergoing radical cystectomy.

INTRODUCTION: Cisplatin-based neoadjuvant chemotherapy (NAC) is the standard of care for patients with muscle-invasive bladder cancer (MIBC) undergoing radical cystectomy (RC). Cisplatin, however, can induce renal toxicity. Furthermore, RC is an independent risk factor for renal injury, with decreases in estimated glomerular filtration rate (eGFR) of up to 6 mL/min/1.73 m2 reported at one year postoperatively. Our objective was to evaluate the effect of cisplatin-based NAC and RC on the renal function of patients undergoing both. METHODS: We analyzed a multicenter database of patients with MIBC, all of whom received cisplatin-based NAC prior to RC. eGFR values were collected at time points T1 (before NAC), T2 (after NAC but before RC), and T3 (one year post-RC). eGFR and proportion of patients with eGFR <60 ml/min/1.73m2 (chronic kidney disease [CKD] stage ≥3) were compared between these time points. As all patients in this dataset had received NAC, we identified a retrospective cohort of patients from one institution who had undergone RC during the same time period without NAC for context. RESULTS: We identified 234 patients with available renal function data. From T1 to T3, there was a mean decline in eGFR of 17% (13 mL/min/1.73 m2) in the NAC cohort and an increase in proportion of patients with stage ≥3 CKD from 27% to 50%. The parallel cohort of patients who did not receive NAC was comprised of 236 patients. The mean baseline eGFR in this cohort was lower than in the NAC cohort (66 vs. 75 mL/min/1.73 m2). The mean eGFR decline in this non-NAC cohort from T1 to T3 was 6% (4 mL/min/1.73 m2), and the proportion of those with stage ≥3 CKD increased from 37% to 51%. CONCLUSIONS: Administration of NAC prior to RC was associated with a 17% decline in eGFR and a nearly doubled incidence of stage ≥3 CKD at one year after RC. Patients who underwent RC without NAC had a higher rate of stage ≥3 CKD at baseline but appeared to have less renal function loss at one year.

Comparing Patient-reported Functional Outcomes After Radical Prostatectomy in Historical and Contemporary Practice.

PURPOSE: Modifications to surgical technique, particularly the widespread adoption of robotic surgery, have been proposed to improve functional recovery after prostate cancer surgery. However, rigorous comparison of men in historical vs contemporary practice to evaluate the cumulative effect of these changes on urinary and sexual function after radical prostatectomy is lacking. MATERIALS AND METHODS: We compared prospectively collected patient-reported urinary and sexual function from historical (PROSTQA [Prostate Cancer Outcomes and Satisfaction With Treatment Quality Assessment study], n=235) and contemporary (MUSIC-PRO [Michigan Urological Surgery Improvement Collaborative Patient Reported Outcome] registry, n=1,215) cohorts at the University of Michigan to understand whether modern techniques have resulted in functional improvements for men undergoing prostate cancer surgery. RESULTS: We found significant differences in baseline function, with better urinary (median [IQR]; 100 [93.8-100] vs 93.8 [85.5-100], P < .001) and sexual scores (median [IQR]; 83.3 [66.7-100] vs 74.4 [44.2-87.5], P < .001) prior to treatment in PROSTQA compared to MUSIC-PRO patients, respectively. There was no statistically significant difference in the pattern of urinary incontinence recovery after surgery from 6-24 months between groups (P = .14). However, men in the contemporary MUSIC-PRO group did have significantly better recovery of sexual function compared to men in the historical PROSTQA group (P < .0001). Further, we found that contemporary practice consists of men with more unfavorable demographic and clinical characteristics compared to historical practice. CONCLUSIONS: Our results demonstrate that the widespread alterations in prostate cancer surgery over the past 2 decades have yielded improvements in sexual, but not urinary, function recovery.

Protocol of a multicentre randomised controlled trial assessing transperineal prostate biopsy to reduce infectiouscomplications.

INTRODUCTION: Approximately one million prostate biopsies are performed annually in the USA, and most are performed using a transrectal approach under local anaesthesia. The risk of postbiopsy infection is increasing due to increasing antibiotic resistance of rectal flora. Single-centre studies suggest that a clean, percutaneous transperineal approach to prostate biopsy may have a lower risk of infection. To date, there is no high-level evidence comparing transperineal versus transrectal prostate biopsy. We hypothesise that transperineal versus transrectal prostate biopsy under local anaesthesia has a significantly lower risk of infection, similar pain/discomfort levels and comparable detection of non-low-grade prostate cancer. METHODS AND ANALYSIS: We will perform a multicentre, prospective randomised clinical trial to compare transperineal versus transrectal prostate biopsy for elevated prostate-specific antigen in the first biopsy, prior negative biopsy and active surveillance biopsy setting. Prostate MRI will be performed prior to biopsy, and targeted biopsy will be conducted for suspicious MRI lesions in addition to systematic biopsy (12 cores). Approximately 1700 men will be recruited and randomised in a 1:1 ratio to transperineal versus transrectal biopsy. A streamlined design to collect data and to determine trial eligibility along with the two-stage consent process will be used to facilitate subject recruitment and retention. The primary outcome is postbiopsy infection, and secondary outcomes include other adverse events (bleeding, urinary retention), pain/discomfort/anxiety and critically, detection of non-low-grade (grade group ≥2) prostate cancer. ETHICS AND DISSEMINATION: The Institutional Review Board of the Biomedical Research Alliance of New York approved the research protocol (protocol number #18-02-365, approved 20 April 2020). The results of the trial will be presented at scientific conferences and published in peer-reviewed medical journals. TRIAL REGISTRATION NUMBER: NCT04815876.

Intra-practice Urologist-level Variation in Targeted Fusion Biopsy Outcomes.

OBJECTIVE: To examine the extent to which the urologist performing biopsy contributes to variation in prostate cancer detection during fusion-guided prostate biopsy. METHODS: All men in the Michigan Urological Surgery Improvement Collaborative (MUSIC) clinical registry who underwent fusion biopsy at Michigan Medicine from August 2017 to March 2019 were included. The primary outcomes were clinically significant cancer detection rate (defined as Gleason Grade ≥2) in targeted cores and clinically significant cancer detection on targeted cores stratified by PI-RADS score. Bivariate and multivariable logistic regression analyses were performed. RESULTS: A total of 1133 fusion biopsies performed by 5 providers were included. When adjusting for patient age, PSA, race, family history, prostate volume, clinical stage, and PI-RADS score, there was no significant difference in targeted clinically significant cancer detection rates across providers (range = 38.5%-46.9%, adjusted P-value = .575). Clinically significant cancer detection rates ranged from 11.1% to 16.7% in PI-RADS 3 (unadjusted P = .838), from 24.6% to 43.4% in PI-RADS 4 (adjusted P = .003), and from 69.4% to 78.8% in PI-RADS 5 (adjusted P = .766) lesions. CONCLUSION: There was a statistically significant difference in clinically significant prostate cancer detection in PI-RADS 4 lesions across providers. These findings suggest that even among experienced providers, variation at the urologist level may contribute to differences in clinically significant cancer detection rates within PI-RADS 4 lesions. However, the relative impact of biopsy technique, radiologist interpretation, and MR acquisition protocol requires further study.

Use of a physical activity monitor to track perioperative activity of radical cystectomy patients. Our first glimpse at what our patients are doing before and after surgery.

PURPOSE: To optimize recovery after radical cystectomy (RC), providers stress the importance of ambulation and adequate rest. However, little is known about the activity and sleep habits of patients undergoing RC. Therefore, we utilized a wearable physical activity monitor (PAM) in the perioperative period to provide the first objective data on physical activity and sleep habits for RC patients. MATERIALS AND METHODS: We prospectively identified patients ≥60 years old with planned RC. Participants completed a 4-week prehabilitation exercise program prior to surgery. They wore a PAM for 7-day intervals: at baseline, after prehabilitation, at postoperative day (POD) 30 and POD90. We tracked physical activity via metabolic equivalents (METs). METs were categorized by intensity: light (MET 1.5-<3), moderate (MET 3-<6), and vigorous (MET ≥6). We calculated daily step totals. We tracked hours slept and number of sleep awakenings. We correlated activity and sleep with self-reported quality of life (QOL). RESULTS: Forty-two patients completed prehabilitation and RC. Moderate intensity exercise decreased at POD30 (61 minutes/d at baseline, 30 minutes/d at POD30, P = 0.005). Physical activity did not significantly differ for light or vigorous activity at any timepoint. RC did not significantly affect sleep. Sleep and physical activity were associated with mental and physical QOL, respectively. CONCLUSIONS: This is the first study utilizing patient-worn monitors in RC to track physical activity and sleep. This study gives patients and providers a better understanding of postcystectomy recovery expectations. With these results in mind, interventions may be implemented to optimize activity and sleep in the perioperative period.

Impact of Maximal Transurethral Resection on Pathological Outcomes at Cystectomy in a Large, Multi-institutional Cohort.

PURPOSE: While the presence of residual disease at the time of radical cystectomy for bladder cancer is an established prognostic indicator, controversy remains regarding the importance of maximal transurethral resection prior to neoadjuvant chemotherapy. We characterized the influence of maximal transurethral resection on pathological and survival outcomes using a large, multi-institutional cohort. MATERIALS AND METHODS: We identified 785 patients from a multi-institutional cohort undergoing radical cystectomy for muscle-invasive bladder cancer after neoadjuvant chemotherapy. We employed bivariate comparisons and stratified multivariable models to quantify the effect of maximal transurethral resection on pathological findings at cystectomy and survival. RESULTS: Of 785 patients, 579 (74%) underwent maximal transurethral resection. Incomplete transurethral resection was more frequent in patients with more advanced clinical tumor (cT) and nodal (cN) stage (P < .001 and P < .01, respectively), with more advanced ypT stage at cystectomy and higher rates of positive surgical margins (P < .01 and P < .05, respectively). In multivariable models, maximal transurethral resection was associated with downstaging at cystectomy (adjusted odds ratio 1.6, 95% CI 1.1-2.5). In Cox proportional hazards analysis, maximal transurethral resection was not associated with overall survival (adjusted HR 0.8, 95% CI 0.6-1.1). CONCLUSIONS: In patients undergoing transurethral resection for muscle-invasive bladder cancer prior to neoadjuvant chemotherapy, maximal resection may improve pathological response at cystectomy. However, the ultimate effects on long-term survival and oncologic outcomes warrant further investigation.

Applicant perceptions of virtual interviews for society of urologic oncology fellowships during the COVID-19 pandemic.

The COVID-19 public health emergency forced the conversion of in-person SUO fellowship interviews into virtual interviews. We sought to understand applicant perspectives and preferences related to virtual interviews and whether programs should consider virtual interviews in the future. We distributed a survey to 2020 SUO Fellowship interview participants at 4 SUO urologic oncology fellowship programs. Response items were on a Likert scale scored 1-5 with higher scores indicating greater agreement with the survey item construct. Survey responses were collated and thematic mapping used to describe open text responses. Descriptive statistics were used for analysis of survey and open text results. Fifty-eight SUO fellowship applicants completed the survey. Virtual interviews successfully promoted interaction with SUO fellowship program faculty (mean 4.6, SD 0.6), outlined program research opportunities (mean 4.5, SD 0.7), and proffered opportunities to ask questions about the fellowship (mean 4.7, SD 0.5). Applicants exhibited weakly positive orientation to the adequacy of the virtual format (mean 3.5, SD 1.1). 63% of applicants would prefer a virtual format in the future. Qualitative feedback noted the benefits of virtual interviews were lower cost and reduced time away from residency. SUO fellowship applicants exhibited mixed preferences for virtual and in-person interviews. Although virtual fellowship interviews have benefits such as cost savings and time efficiency, notable weaknesses included challenges observing the culture of the programs. Following the pandemic, SUO fellowship programs may consider virtual interviews but should consider incorporating opportunities for informal interactions between faculty, fellows, and fellow applicants.

Multicenter evaluation of neoadjuvant and induction gemcitabine-carboplatin versus gemcitabine-cisplatin followed by radical cystectomy for muscle-invasive bladder cancer.

PURPOSE: Cisplatin-based chemotherapy followed by radical cystectomy (RC) is recommended in patients with muscle-invasive bladder cancer (MIBC). However, up to 50% of patients are cisplatin ineligible. The aim of this study was to compare clinical outcomes after ≥ 3 cycles of preoperative gemcitabine-carboplatin (gem-carbo) versus gemcitabine-cisplatin (gem-cis). METHODS: We identified 1865 patients treated at 19 centers between 2000 and 2013. Patients were included if they had received ≥ 3 cycles of neoadjuvant (cT2-4aN0M0) or induction (cTanyN + M0) gem-carbo or gem-cis followed by RC. RESULTS: We included 747 patients treated with gem-carbo (n = 147) or gem-cis (n = 600). Patients treated with gem-carbo had a higher Charlson Comorbidity Index (p = 0.016) and more clinically node-positive disease (32% versus 20%; p = 0.013). The complete pathological response (pCR; ypT0N0) rate did not significantly differ between gem-carbo and gem-cis (20.7% versus 22.1%; p = 0.73). Chemotherapeutic regimen was not significantly associated with pCR (OR 0.99 [95%CI 0.61-1.59]; p = 0.96), overall survival (OS) (HR 1.20 [95%CI 0.85-1.67]; p = 0.31), or cancer-specific survival (CSS) (HR 1.35 [95%CI 0.93-1.96]; p = 0.11). Median OS of patients treated with gem-carbo and gem-cis was 28.6 months (95%CI 18.1-39.1) and 45.1 months (95%CI 32.7-57.6) (p = 0.18), respectively. Median CSS of patients treated with gem-carbo and gem-cis was 28.8 months (95%CI 9.8-47.8) and 71.0 months (95%CI median not reached) (p = 0.02), respectively. Subanalyses of the neoadjuvant and induction setting did not show significant survival differences. CONCLUSION: Our results show that a subset of cisplatin-ineligible patients with MIBC achieve pCR on gem-carbo and that survival outcomes seem comparable to gem-cis provided patients are able to receive ≥ 3 cycles and undergo RC.

NCCN Guidelines® Insights: Bladder Cancer, Version 2.2022.

The NCCN Guidelines for Bladder Cancer provide recommendations for the diagnosis, evaluation, treatment, and follow-up of patients with bladder cancer and other urinary tract cancers (upper tract tumors, urothelial carcinoma of the prostate, primary carcinoma of the urethra). These NCCN Guidelines Insights summarize the panel discussion behind recent important updates to the guidelines regarding the treatment of non-muscle-invasive bladder cancer, including how to treat in the event of a bacillus Calmette-Guérin (BCG) shortage; new roles for immune checkpoint inhibitors in non-muscle invasive, muscle-invasive, and metastatic bladder cancer; and the addition of antibody-drug conjugates for metastatic bladder cancer.

TERT Promoter Mutations in Keratinizing and Nonkeratinizing Squamous Metaplasia of the Urinary Tract.

We identified urothelial tract biopsy and resection specimens with keratinizing squamous metaplasia (KSM), nonkeratinizing squamous metaplasia (NKSM), and urothelial and squamous carcinomas over a 20-yr period, focusing on cases with neurogenic lower urinary tract dysfunction (NLUTD) and/or those with spatial or temporal variation in sampling. TERT promoter mutations as assessed via allele-specific polymerase chain reaction were surprisingly common in our testing cohort, identified not only in 15 (94%) invasive cancer foci but also in 13 (68%) examples of KSM and seven (70%) examples of NKSM. TERT promoter mutations were present in 23 foci from NLUTD specimens and 11 foci from bladder diverticula, including in foci of KSM, NKSM, and unremarkable urothelium from cases with no clinical association with previous, concurrent, or subsequent cancer. Our demonstration of temporally and spatially persistent TERT promoter mutation in examples of KSM and NKSM in cases of bladder cancer and in morphologically benign cases with neurogenic dysfunction suggests a molecular mechanism by which such pre-neoplastic lesions can potentially progress and develop into overt carcinoma. Given the interest in TERT promoter mutations as a potential biomarker for the development of bladder cancer, these findings possibly explain the association between conditions with chronic urinary bladder injury (such as the natural history of NLUTD) and higher risk of bladder cancer. TERT promoter mutations may represent an early event in bladder cancer tumorogenesis, and our findings expand on the clinical ramifications and predictive value of TERT promoter mutations in this context. PATIENT SUMMARY: Mutations in the TERT gene are the most common genetic changes in bladder cancer. We found that these mutations are also sometimes present in patients with chronic bladder irritation such as neurogenic bladder dysfunction and changes to the lining of the bladder that pathologists would consider "benign." This finding might explain why such conditions are associated with the development of bladder cancer.
