Racial Differences in the Detection Rate of Bladder Cancer Using Blue Light Cystoscopy: Insights from a Multicenter Registry.

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.

Predicting Peak Productivity in Urologic Medicare Practice via Work-Relative Value Units.

OBJECTIVE: To explore factors associated with productivity in urologic practice. Work-relative value units (wRVUs), the basis for Center for Medicare & Medicaid Services (CMS) and private payer reimbursements, commonly serve to estimate physician productivity. Limited data describes which practice factors predict increased wRVU productivity. METHODS: The 2017 and 2018 CMS databases were retrospectively queried for urologic Medicare provider demographics and procedural/service details. Medical school graduation year was used to estimate years in practice and generation (Millennial, Gen X, Baby Boomer, or Post-War). Treated patients' demographics were obtained. Adjusted and unadjusted linear mixed models were performed to predict wRVU production. RESULTS: Included were 6773 Medicare-participating urologists across the United States. Millennials produced 1115 wRVUs per year, while Gen X and Baby Boomers produced significantly more (1997 and 2104, respectively, P <.01). Post-War urologists produced numerically more (1287, P = .88). In adjusted analyses, predictors of Medicare wRVU productivity included female and pelvic medicine and reconstructive surgery (exponentiated beta estimate (ß) 1.46, 95% CI 1.32-1.60), men's health (ß 1.22, 95% CI 1.13-1.32), and oncologic subspecialization (ß 1.08, 95% CI 1.02-1.14), female gender (ß 0.87, 95% CI 0.82-0.92), wRVUs generated from inpatient procedures (ß 1.08, 95% CI 1.06-1.09) and office visits (ß 0.88, 95% CI 0.87-0.89), and the level of education (ß 1.10, 95% CI 1.07-1.14) and percent impoverished patients (ß 0.85, 95% CI 0.83-0.88) in provider's practice zip code. CONCLUSION: Urologic experience, specialization, demographics, practice patterns, and patient demographics are significantly associated with wRVU productivity in Medicare settings. Further work should incorporate quality metrics into wRVUs and ensure patient demographics do not affect reimbursement.

Association of household net worth with healthcare costs after radical cystectomy using real-world data.

BACKGROUND: Financial toxicity of bladder cancer care may influence how patients utilize healthcare resources, from emergency department (ED) encounters to office visits. We aim to examine whether greater household net worth (HHNW) confers differential access to healthcare resources after radical cystectomy (RC). METHODS: This population-based cohort study examined the association between HHNW and healthcare utilization costs in the 90 days post-RC in commercially insured patients with bladder cancer. Costs accrued from the index hospitalization to 90 days after including health plan costs (HPC) and out-of-pocket costs (OPC). Multivariable logistic regression models were generated by encounter (acute inpatient, ED, outpatient, and office visit). RESULTS: A total of 141,903 patients were identified with HHNW categories near evenly distributed. Acute inpatient encounters incurred the greatest HPC and OPC. Office visits conferred the lowest HPC while ED visits had the lowest OPC. Black patients harbored increased odds of an acute inpatient encounter (OR 1.22, 95% CI 1.16-1.29) and ED encounter (OR 1.20, 95% CI 1.14-1.27) while Asian (OR 0.76, 95% CI 0.69-0.85) and Hispanic (OR 0.74, 95% CI 0.69-0.78, p < 0.001) patients had lower odds of an outpatient encounter, compared to White counterpart. Increasing HHNW was associated with decreasing odds of acute inpatient or ED encounters and greater odds of office visits. CONCLUSIONS: Lower HHNW conferred greater risk of costly inpatient encounters while greater HHNW had greater odds of less costly office visits, illustrating how financial flexibility fosters differences in healthcare utilization and lower costs. HHNW may serve as a proxy for financial flexibility and risk of financial hardship than income alone.

Evaluation of URO17® to improve non-invasive detection of bladder cancer.

BACKGROUND: The gold standard for detecting bladder cancer is cystoscopy with biopsy or transurethral resection confirming histologic diagnosis. URO17® employs a chromogenically labeled monoclonal antibody to keratin 17 (k17), an intermediate filament cytoskeleton molecule associated with bladder, pancreatic, and cervical cancers. Preliminary studies evaluating k17 demonstrated a high sensitivity and specificity for the detection of bladder cancer, supporting the need for further study. OBJECTIVE: To evaluate the sensitivity and specificity of URO17. METHODS: This is a cross-sectional study of participants undergoing urologic procedures between July 6, 2018 and July 17, 2019 at a single institution. Patients undergoing cystectomy, endoscopic bladder and/or upper tract procedure for probable urothelial carcinoma comprised cases; patients undergoing urologic procedures for other reasons comprised the control group (i.e. prostatectomy, nephrectomy, etc.). Voided urine samples were at the time of procedure; a minority of participants underwent multiple resections in the study period, thus, as many as three urine samples were taken from any given participant. Samples were distributed for blinded testing with URO17. Sensitivity and specificity were calculated. RESULTS: In 152 participants and 167 samples, URO17 demonstrated an overall sensitivity of 90% and 92% and a specificity of 88% and 87%, respectively. In 76 participants and 91 samples from patients with suspected urothelial carcinoma, the sensitivity was 90% and 92%, and the specificity was 50% and 54%, respectively. No controls demonstrated a positive URO17 result, and URO17 superseded urine cytology detection of low-grade and high-grade Ta. False positive results were associated with inflamed tissue or urothelial atypia on histology; the large majority had a history of intravesical therapy. CONCLUSION: Limitations include cross-sectional design and convenience sampling. URO17 may improve sensitivity of urine cytology in the detection of urothelial cancer, though further study is required to refine the application of this biomarker in clinical practice.

"I think my vagina is still there?": Women's perspectives on sexual function and dysfunction following radical cystectomy for bladder cancer, a qualitative study.

BACKGROUND: Women's sexual health after radical cystectomy is an important but poorly understood aspect of bladder cancer survivorship. Dedicated investigation is needed to elucidate patient perceptions on sexual function and dysfunction in this setting. AIMS: In this study we sought to qualitatively examine women's perceptions and experiences of sexual health following radical cystectomy for bladder cancer. METHODS: We conducted one-on-one qualitative telephone interviews with 40 women who underwent radical cystectomy in the past 6 months to 5 years and signed a research consent form to be contacted for future studies. We examined women's experiences of engaging in sexual activity after surgery and their attitudes toward sex and body image. We audio recorded, transcribed, and coded the interviews using ATLAS.ti software and applied grounded theory methods for analysis. OUTCOMES: For data that emerged during the qualitative interviews that was related to lack of knowledge about how physical and psychological sexual health would be affected after surgery, we reviewed and discussed transcripts that enabled coding of the data into emerging topic areas. RESULTS: Our analysis yielded 4 main themes. (1) Women reported receiving little to no information from providers about female sexual dysfunction prior to or after radical cystectomy. Women wished they had been provided more information about female sexual dysfunction from their clinicians, including strategies for postoperative self-pleasure and nonintercourse methods of sexual pleasure with partners. (2) Women shared that they were not sexually active following surgery due to physical and mental barriers. (3) When women did try to engage in sex, they described feeling disappointed that it did not feel the same as prior to surgery. (4) Some women found that physical therapy helped them to physically and mentally recover their strength to engage in sexual activity again. CLINICAL IMPLICATIONS: Clinicians must directly address sexual health concerns with patients who undergo radical cystectomy. STRENGTHS AND LIMITATIONS: This study has several key strengths. Investigation into women's sexual function and dysfunction addresses a gap in understanding of this component of women's health-related quality of life after radical cystectomy, which represents an unmet need. The large number of interviews conducted as well as the in-depth information obtained through one-on-one interviews are additional strengths. This study also has limitations, including possible shortcomings of telephone interviews compared with in-person interviews. However, telephone interviews were beneficial because the interviews took place during the COVID-19 pandemic and spared patients from extra visits or from having to travel long distances to the respective medical centers. Other possible limitations were that patients may have been reluctant to share all of their experiences and that patients who underwent urostomies, also termed ileal conduits, were overrepresented in this study compared with women who underwent continent urine diversions, which allow greater control over urine output. CONCLUSION: Broadening the understanding of sexual health beyond sexual intercourse to encompass sexuality and self-pleasure can provide clinicians, patients, and their families with more effective preparation and strategies to care for an essential aspect of their wellbeing.

Standardization of the evaluation and surveillance of patients with BCG unresponsive high grade non-muscle invasive bladder cancer clinical trials.

There are multiple ongoing and planned clinical trials that are evaluating novel therapies to treat patients with BCG-unresponsive high grade nonmuscle invasive bladder cancer (NMIBC). Importantly, there is considerable variation in surveillance strategies between these clinical trials, specifically with regards to the use of advanced imaging, enhanced cystoscopy, and mandatory biopsies, which could impact landmark efficacy assessments of investigational agents. To present guideline recommendations for the standardization of cystoscopic evaluation, surveillance, and efficacy assessments for patients with BCG-unresponsive NMIBC participating in clinical trials. On September 29, 2023 at the annual meeting of the International Bladder Cancer Network, a breakout session was convened, during which representatives from various disciplines discussed potential guidance statements with opportunity for discussion and comment. A set of statements regarding use of white light and enhanced cystoscopy were developed to help guide a pragmatic approach to surveillance and efficacy assessments of patients in clinical trials. The use of "for cause" and "mandatory" biopsies was also addressed. A standard approach to evaluation of patients within the context of clinical trials is necessary to accurately assess the efficacy of novel agents, especially within single arm trials that lack an appropriate comparator. Additionally, the utilization and timing of mandatory biopsies is critical, as these biopsies may impact both disease evaluations and the determination of duration of response.

Initial Experience with 68Ga-FAP-2286 PET Imaging in Patients with Urothelial Cancer.

Improved imaging modalities are needed to accurately stage patients with muscle-invasive bladder cancer (MIBC) and metastatic urothelial carcinoma. Imaging with small-molecule ligands or inhibitors of fibroblast activation protein (FAP) is a promising modality that has demonstrated initial efficacy across a broad range of tumors. We present our experience with the novel FAP-peptide binder 68Ga-FAP-2286 in patients with MIBC. Methods: Patients with histopathologically confirmed bladder cancer who had either localized disease at diagnosis (localized cohort, n = 13) or known metastatic disease (metastatic cohort, n = 8) were imaged with 68Ga-FAP-2286 PET as part of a clinical trial (NCT04621435). The SUVmax of 68Ga-FAP-2286 PET-positive lesions and lesion size were documented. In patients who had available 18F-FDG PET performed within 45 d of 68Ga-FAP-2286 PET (n = 5), uptake on the 2 scans was compared. When there was a discrepancy between imaging modalities on retrospective review, biopsy of suggestive lesions was performed as the standard of care. Results: In the metastatic and localized cohorts, 36 and 18 68Ga-FAP-2286-avid lesions, respectively, were identified across multiple anatomic locations, including lymph nodes, visceral metastases, and bones. Fourteen of 36 lesions in the metastatic cohort and 14 of 18 lesions in the localized cohort were lymph nodes measuring less than 1 cm. Among lesions measuring less than 0.5 cm, 0.5-1 cm, and more than 1 cm, average SUVmax was 5.2 ± 2.6, 9.6 ± 3.7, and 13.0 ± 4.3, respectively, in the metastatic cohort and 10.5 ± 5.1, 10.8 ± 5.7, and 9.9 ± 5.4, respectively, in the localized cohort. Five patients had 18F-FDG PET available for comparison. The average SUVmax for lesions avid on 68Ga-FAP-2286 PET and 18F-FDG PET was 9.9 ± 3.4 versus 4.2 ± 1.9, respectively (n = 16 lesions). For 3 patients in the localized cohort, 68Ga-FAP-2286 PET informed clinical management, including identification of both false-positive findings on 18F-FDG PET and false-negative findings on conventional CT. Conclusion: 68Ga-FAP-2286 imaging is highly sensitive in patients with urothelial cancer and is effective in identifying metastatic lesions across a variety of anatomic sites, including subcentimeter lymph nodes that would not have raised suspicion on conventional scans. This novel imaging modality may inform clinical decision-making in patients with MIBC both by refining local nodal staging and by defining metastatic disease that would otherwise be undetectable on conventional imaging.

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.

Protocol of the Comparison of Intravesical Therapy and Surgery as Treatment Options (CISTO) study: a pragmatic, prospective multicenter observational cohort study of recurrent high-grade non-muscle invasive bladder cancer.

BACKGROUND: Bladder cancer poses a significant public health burden, with high recurrence and progression rates in patients with non-muscle-invasive bladder cancer (NMIBC). Current treatment options include bladder-sparing therapies (BST) and radical cystectomy, both with associated risks and benefits. However, evidence supporting optimal management decisions for patients with recurrent high-grade NMIBC remains limited, leading to uncertainty for patients and clinicians. The CISTO (Comparison of Intravesical Therapy and Surgery as Treatment Options) Study aims to address this critical knowledge gap by comparing outcomes between patients undergoing BST and radical cystectomy. METHODS: The CISTO Study is a pragmatic, prospective observational cohort trial across 36 academic and community urology practices in the US. The study will enroll 572 patients with a diagnosis of recurrent high-grade NMIBC who select management with either BST or radical cystectomy. The primary outcome is health-related quality of life (QOL) at 12 months as measured with the EORTC-QLQ-C30. Secondary outcomes include bladder cancer-specific QOL, progression-free survival, cancer-specific survival, and financial toxicity. The study will also assess patient preferences for treatment outcomes. Statistical analyses will employ targeted maximum likelihood estimation (TMLE) to address treatment selection bias and confounding by indication. DISCUSSION: The CISTO Study is powered to detect clinically important differences in QOL and cancer-specific survival between the two treatment approaches. By including a diverse patient population, the study also aims to assess outcomes across the following patient characteristics: age, gender, race, burden of comorbid health conditions, cancer severity, caregiver status, social determinants of health, and rurality. Treatment outcomes may also vary by patient preferences, health literacy, and baseline QOL. The CISTO Study will fill a crucial evidence gap in the management of recurrent high-grade NMIBC, providing evidence-based guidance for patients and clinicians in choosing between BST and radical cystectomy. The CISTO study will provide an evidence-based approach to identifying the right treatment for the right patient at the right time in the challenging clinical setting of recurrent high-grade NMIBC. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03933826. Registered on May 1, 2019.

Phase 2 Trial of Atezolizumab in Bacillus Calmette-Guérin-unresponsive High-risk Non-muscle-invasive Bladder Cancer: SWOG S1605.

BACKGROUND: Although radical cystectomy (RC) is the standard of care for patients with bacillus Calmette-Guérin (BCG)-unresponsive high-risk non-muscle-invasive bladder cancer (NMIBC), many patients are ineligible for surgery or elect bladder preservation. OBJECTIVE: To evaluate the efficacy and safety of atezolizumab in BCG-unresponsive high-risk NMIBC. DESIGN, SETTING, AND PARTICIPANTS: This was a single-arm phase 2 trial in patients with BCG-unresponsive high-risk NMIBC who were ineligible for or declined RC. INTERVENTION: Intravenous atezolizumab every 3 wk for 1 yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary endpoint was the pathological complete response (CR) rate for patients with carcinoma in situ (CIS) determined via mandatory biopsy at 6 mo. Event-free survival (EFS) at 18 mo for patients with non-CIS tumors and treatment-related adverse events (TRAEs) were key secondary endpoints. RESULTS AND LIMITATIONS: Of 172 patients enrolled in the trial, 166 received at least one dose of atezolizumab (safety analysis) and 129 were eligible (efficacy analysis). Of the 74 patients with CIS, 20 (27%) experienced a CR at 6 mo. The median duration of response was 17 mo, and 56% (95% confidence interval [CI] 34-77%) of the responses were durable to at least 12 mo. The 18-mo actuarial EFS rate among 55 patients with Ta/T1 disease was 49% (90% CI 38-60%). Twelve of 129 eligible patients experienced progression to muscle-invasive or metastatic disease. Grade 3-5 TRAEs occurred in 26 patients (16%), including three treatment-related deaths. The study was limited by the small sample size and a high rate of patient ineligibility. CONCLUSIONS: The efficacy of atezolizumab observed among patients with BCG-unresponsive NMIBC is similar to results from similar trials with other agents, but did not meet the prespecified efficacy threshold. Modest efficacy needs to be balanced with a significant rate of TRAEs and the risk of disease progression when considering systemic immunotherapy in early-stage bladder cancer. PATIENT SUMMARY: We tested intravenous immunotherapy (atezolizumab) in patients with high-risk non-muscle-invasive bladder cancer that recurred after BCG (bacillus Calmette-Guérin) treatment. Although we found similar outcomes to previous trials, the benefit of this therapy is modest and needs to be carefully balanced with the significant risk of side effects. This trial is registered on ClinicalTrials.gov as NCT02844816.

Background and Update for ECOG-ACRIN EA8212: A Randomized Phase 3 Trial of Intravesical Bacillus Calmette-Guérin (BCG) Versus Intravesical Docetaxel and Gemcitabine Treatment in BCG-naïve High-grade Non-muscle-invasive Bladder Cancer (BRIDGE).

Impact of Squamous Histology on Clinical Outcomes and Molecular Profiling in Metastatic Urothelial Carcinoma Patients Treated With Immune Checkpoint Inhibitors or Enfortumab Vedotin.

INTRODUCTION: Urothelial carcinoma with squamous differentiation (UCS) is associated with increased resistance to chemotherapy, but outcomes associated with newer therapies approved in this space over the last 5 to 10 years are less well defined. We investigated clinical outcomes and molecular profiling of patients with UCS treated with an immune checkpoint inhibitor (ICI) and/or Enfortumab vedotin (EV). PATIENTS AND METHODS: We undertook a retrospective analysis of UC patients treated with ICI and/or EV. Objective response rate (ORR), progression free survival (PFS) and overall survival (OS) were compared between pure UC (pUC) and UCS using X2 and log-rank tests, respectively. Prevalence of the most commonly detected somatic alterations were also compared between the 2 histologic subgroups. RESULTS: A total of 160 patients (40 UCS, 120 pUC) were identified for this analysis. Among 151 patients treated with ICI (38 UCS, 113 pUC), UCS patients had a shorter mPFS (1.9 vs. 4.8 months, P < 0.01) and mOS (9.2 vs. 20.7 months, P < 0.01) compared to pUC. Among 37 patients treated with EV (12 UCS, 25 pUC), UCS patients had a lower ORR (17% vs. 70%, P < 0.01) and shorter mPFS (3.4 vs. 15.8 months, P < 0.01). UCS samples were enriched for CDKN2A, CDKN2B, PIK3CA, while pUC samples were enriched for ERBB2 alterations. CONCLUSION: In this single-center retrospective analysis, patients with UCS had a distinct somatic genomic profile relative to patients with pUC. Patients with UCS also had inferior outcomes to ICIs and EV compared to patients with pUC.

Readmissions trends following radical cystectomy for bladder cancer unchanged in the era of enhanced recovery after surgery (ERAS) protocols.

PURPOSE: To provide nationally representative estimates of contemporary trends in readmission rates, readmission location (index vs. nonindex hospital), and causes of readmission following radical cystectomy (RC) in the era of enhanced recovery after surgery (ERAS) protocol implementation. MATERIALS AND METHODS: Patients with bladder cancer who underwent RC were identified in the Nationwide Readmissions Database (2016-2019). Yearly trends in 30-day and 90-day readmission rates and readmission causes were assessed in the whole cohort and subset of patients who underwent RC at high volume centers (>22 RCs/year). Multivariable logistic regression was used to determine predictors of index readmission, nonindex readmission, death during readmission, and experiencing a second readmission. RESULTS: Among the 20,957 RC patients, the 30-day and 90-day readmission rates were 23.5% (n = 4,931) and 39.1% (n = 7,987), respectively. For 90-day readmissions, 27.6% (n = 2,206) were to nonindex hospitals. During the study period, there was no significant change in the yearly 30-day or 90-day readmission rates and percentage of readmissions to nonindex hospitals (all p > 0.05). This was also true in the subset of patients who underwent RC at high volume centers. The only significant change in causes of readmission during the study period was wound readmissions (2.7% in 2016 vs. 5.1% of readmissions in 2019, p = 0.02). CONCLUSIONS: During the era of ERAS protocol implementation, in this nationally representative study, most causes of readmission and both 30 and 90-day readmission rates were unchanged, even at high volume RC centers. Moving forward, novel interventions are needed which focus on the postdischarge recovery period to help decrease readmission rates following RC.

Somatic alterations of TP53 and MDM2 associated with response to enfortumab vedotin in patients with advanced urothelial cancer.

Background: Enfortumab vedotin (EV) is an antibody-drug conjugate approved for patients with treatment-refractory advanced urothelial carcinoma (aUC), however data on biomarkers of response is lacking. Methods: We retrospectively identified all aUC patients at our institution who received EV monotherapy and had next-generation sequencing (NGS) data available. Patients were considered responders if they had a complete response or partial response on restaging scans during treatment. Observed response rate (ORR) was evaluated by local investigator and compared between responders and non-responders using Chi-squared test. A univariable analysis was conducted using the Cox proportional hazard test to assess for associations between baseline characteristics and most common somatic alterations (in ≥10% of patients) with patient survival outcomes [progression-free survival (PFS) and overall survival (OS)]. Somatic alterations were then individually evaluated in separate multivariate models while accounting for patient and clinical characteristics using Cox regression models. Results: Among 29 patients treated with EV monotherapy, 27 had available NGS data. Median age was 70, 24 (83%) were men, 19 (62%) were Caucasian, 15 (52%) had pure urothelial histology and 22 (76%) had primary tumor in the bladder. ORR was 41%, and PFS and OS for the overall cohort were 5.1 months and 10.2 months. Responders were enriched among patients with TP53, KDM6A and MDM2 alterations. Patients with these alterations, as well as those with composite TP53/MDM2 alterations (alterations in either TP53 or MDM2), also had increased ORR with EV treatment compared to patients without these alterations. In the univariable analysis, baseline albumin level ≥ 3.0g/dL and presence of composite TP53/MDM2 alterations were associated with a prolonged OS. Baseline ECOG 0/1, TP53 alterations and TP53/MDM2 alterations were associated with a prolonged PFS. In the multivariable analysis, TP53 and TP53/MDM2 alterations were genomic markers predictive of improved PFS after accounting for the relevant clinical characteristics. Conclusion: In this single-center retrospective analysis of aUC patients treated with EV, presence of TP53 or MDM2 somatic alterations, lower ECOG PS scores (ECOG 0 or 1) and higher albumin levels (≥3 g/dL) were associated with improved outcomes with EV treatment. Prospective and external validation of these findings in larger cohorts is warranted.

Cxbladder Monitor testing to reduce cystoscopy frequency in patients with bladder cancer.

PURPOSE: Bladder cancer surveillance is associated with high costs and patient burden. CxMonitor (CxM), a home urine test, allows patients to skip their scheduled surveillance cystoscopy if CxM-negative indicating a low probability of cancer presence. We present outcomes from a prospective multi-institutional study of CxM to reduce surveillance frequency during the coronavirus pandemic. MATERIALS AND METHODS: Eligible patients due for cystoscopy from March-June 2020 were offered CxM and skipped their scheduled cystoscopy if CxM-negative. CxM-positive patients came for immediate cystoscopy. The primary outcome was safety of CxM-based management, assessed by frequency of skipped cystoscopies and detection of cancer at immediate or next cystoscopy. Patients were surveyed on satisfaction and costs. RESULTS: During the study period, 92 patients received CxM and did not differ in demographics nor history of smoking/radiation between sites. 9 of 24 (37.5%) CxM-positive patients had 1 T0, 2 Ta, 2 Tis, 2 T2, and 1 Upper tract urothelial carcinoma (UTUC) on immediate cystoscopy and subsequent evaluation. 66 CxM-negative patients skipped cystoscopy, and none had findings on follow-up cystoscopy requiring biopsy. Six of these patients did not attend follow-up, 4 elected to undergo additional CxM instead of cystoscopy, 2 stopped surveillance, and 2 died of unrelated causes. CxM-negative and positive patients did not differ in demographics, cancer history, initial tumor grade/stage, AUA risk group, or number of prior recurrences. Median satisfaction (5/5, IQR 4-5) and costs (26/33, 78.8% no out-of-pocket costs) were favorable. CONCLUSIONS: CxM safely reduces frequency of surveillance cystoscopy in real-world settings and appears acceptable to patients as an at-home test.

Is a restaging TURBT necessary in high-risk NMIBC if the initial TURBT was performed with blue light?

OBJECTIVES: To evaluate whether a restaging transurethral resection of bladder tumor (TURBT) is necessary in high-risk nonmuscle invasive bladder cancer (NMIBC) if the initial TURBT was performed using blue light (BL) technology. METHODS AND MATERIALS: Using the multi-institutional Cysview registry between 2014 and 2021, all consecutive adult patients with known NMIBC (Ta and T1 disease) who underwent TURBT followed by a restaging TURBT within 8 weeks were reviewed. Patients were stratified according to their initial TURBT, BL vs. white light (WL), and compared to determine rates of residual disease and upstaging. Univariate analysis was performed using Mann-Whitney U and chi-square tests, with P < 0.05 considered significant. RESULTS: Overall, 115 patients had TURBT for NMIBC followed by a restaging TURBT within 8 weeks and were included in the analysis. Patients who underwent BL compared to WL for their initial TURBT had higher rates of benign pathology on restaging TURBT, although this was not statistically significant (47% vs. 30%; P = 0.08). Of patients with residual tumors on restaging TURBT, there were no differences in rates of Ta (22% vs. 26.5%; P = 0.62), T1 (22% vs. 26.5%; P = 0.62), or CIS (5.5% vs. 13%; P = 0.49) when the initial TURBT was done using BL compared to WL. Rates of upstaging to muscle invasive disease were also not different when initial TURBT was performed using BL compared to WL (3% vs. 4%; P = 0.78). CONCLUSIONS: TURBT using BL does not reduce rates of residual disease or risk of upstaging on restaging TURBT in Ta or T1 disease. Thus, a restaging TURBT is still necessary even if initial TURBT was performed using BL.

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.

Wake-Up Call to Address Sleep Health in Non-Muscle Invasive Bladder Cancer: Underappreciated Contributor to Poor Quality of Life.

BACKGROUND: Few studies have specifically examined sleep health in patients with non-muscle invasive bladder cancer (NMIBC). Further study is warranted to inform future strategies in patients with NMIBC. OBJECTIVE: We aim to describe sleep health in a cohort of patients with NMIBC, and its relationship with quality of life (QOL). METHODS: We conducted an observational cross-sectional study in patients undergoing surveillance for NMIBC. The validated Pittsburgh Sleep Quality Index (PSQI) was used to assess sleep health (scores from 0-21) in the overall study population as well as stratified. We assessed QOL among participants with and without poor sleep quality using the SF-12 and QLQ-NMIBC-24. RESULTS: In a cohort of 94 NMIBC patients, median age was 67 years (IQR: 58, 72) and median time since initial diagnosis was 27 months (IQR: 9, 41). The mean PSQI score was 6.3 (SD: 3.8) and 64% percent of participants met or exceeded the PSQI cut-off score of 5, with a score of 5 or more indicating overall poor sleep quality. In those with poor sleep quality, there were statistically significant detriments in multiple QOL domains. CONCLUSIONS: In patients undergoing surveillance for NMIBC, there is a substantial burden of sleep disturbances and resulting decrements in QOL. These data support the need for future interventions to support sleep quality and highlight the importance of addressing sleep health as part of NMIBC survivorship care to improve QOL in patients with NMIBC.

Epidemiology, Screening, and Prevention of Bladder Cancer.

CONTEXT: Bladder cancer (BC) represents a significant health problem due to the potential morbidity and mortality associated with disease burden, which has remained largely unaltered over time. OBJECTIVE: To provide an expert collaborative review and describe the incidence, prevalence, and mortality of BC and to evaluate current evidence for BC screening and prevention. EVIDENCE ACQUISITION: Data on the estimated incidence and mortality of BC for 2020 in 185 countries were derived from the International Agency for Research on Cancer GLOBOCAN database. A review of English-language articles published over the past 5 yr was conducted using PubMed/MEDLINE to identify risk factors in addition to contemporary evidence on BC screening and prevention. EVIDENCE SYNTHESIS: BC is the tenth most common cancer worldwide, with 573 278 cases in 2020. BC incidence is approximately fourfold higher in men than women. Tobacco smoking remains the principal risk factor, accounting for approximately 50% of cases. There is insufficient evidence to recommend routine BC screening. However, targeted screening of high-risk individuals (defined according to smoking history or occupational exposure) may reduce BC mortality and should be the focus of prospective randomized trials. In terms of disease prevention, smoking cessation represents the most important intervention, followed by a reduction in exposure to occupational and environmental carcinogens. CONCLUSIONS: BC confers a significant disease burden. An understanding of BC epidemiology and risk factors provides an optimal foundation for disease prevention and the care of affected patients. PATIENT SUMMARY: Bladder cancer is the tenth most common cancer worldwide and is approximately four times more common among men than among women. The main risk factors are tobacco smoking, followed by exposure to carcinogens in the workplace or the environment. Routine screening is not currently recommended, but may be beneficial in individuals at high risk, such as heavy smokers. Primary prevention is extremely important, and smoking cessation represents the most important action for reducing bladder cancer cases and deaths.
