Purpose: To describe the incidence and management of patients who develop a prostatic urethral (PU) urothelial carcinoma recurrence after Bacillus Calmette-Guerin (BCG) induction for non-muscle invasive bladder cancer (NMIBC)., Materials and Methods: We performed a retrospective cohort study of all patients who received BCG induction at our institution from 1996 to 2021 (N = 642) for NMIBC. All patients with pathologically confirmed PU involvement following BCG induction with no known PU involvement pre-BCG were included. We describe the presentation, management, and outcomes for PU recurrence., Results: Among the 642 patients, 21 (3.3%) patients had a PU recurrence after BCG induction. 8 (38%) patients received >2 cycles of BCG induction prior to the recurrence. Median time from induction to PU recurrence was 21 months and 12 (57.1%) patients had concurrent bladder recurrence. At the time of their PU recurrence, 14/21 (67%) of patients were deemed BCG Unresponsive. Nearly all (18/21) were high grade, and 10 were stage Tis, 7 Ta, and 3 T1, and 1 T2. 19/21 (90%) patients received bladder sparing treatment: 6 with TURBT and BCG, 6 with TURBT and intravesical chemotherapy, 5 with TURBT only, and 2 did not receive immediate treatment of their PU recurrence due to advanced stage of disease. 2/21 (9.5%) received a radical cystectomy for initial treatment of the post-BCG PU recurrence, of which all were >pT2. Median follow-up time from BCG induction to the patient's last visit was 64.5 months. Following treatment of PU recurrence, 15/18 patients had another recurrence at a median of 5 months: about 47% of recurrences were bladder only and 14% recurred only in the PU as well. About 1 patient received a RC after the second recurrence and was pT2., Conclusion: Patients with PU recurrences following intravesical BCG have a high-risk disease phenotype with a significant risk of recurrence. Conservative management may be appropriate for well-selected patients who do not desire a cystoprostatectomy., (Copyright © 2024 Elsevier Inc. All rights reserved.)

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., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Purpose: While radical cystectomy (RC) is the standard of care for muscle invasive bladder cancer (MIBC), partial cystectomy (PC) is an effective alternative in select patients. We sought to examine differences in survival for RC and PC in a hospital-based registry., Material and Methods: We identified patients diagnosed with cT2-4 bladder cancer who underwent RC or PC from 2003 to 2015 in the National Cancer Database (NCDB). Using inverse probability treatment weighting (IPTW) to control for known confounders, we compared the primary outcome of overall survival (OS) in patients who underwent RC vs. PC. Kaplan-Meier survival analysis, univariable and multivariable Cox proportional hazards modeling were used. We performed a secondary survival analysis for a subcohort of patients with cT2, cN0, tumor size ≤5 cm, and no concurrent carcinoma in situ (CIS), who may be optimal candidates for PC., Results: A total of 22,534 patients met inclusion criteria, of which 6.9% (1,457) underwent PC. RC had longer median OS than PC (67.8 vs. 54.1 months) and on Cox regression analysis (HR 0.88, 95% CI, 0.80-0.95, P = 0.002). However, in our subcohort, there was no difference in OS between RC and PC (HR 1.02, 95% CI, 0.9-1.2, P = 0.74). PC was associated with increased time from surgery to any systemic therapy or death in the subcohort., Conclusions: Among patients with clinically organ-confined MIBC, PC appears to afford similar survival outcomes to RC in a large national data set. The safety and tolerability of PC may warrant consideration in highly selected patients., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Inc.

Background: Novel treatments and trial designs remain a high priority for bacillus Calmette-Guerin (BCG)-unresponsive non-muscle-invasive bladder cancer (NMIBC) patients., Objective: To evaluate the safety and preliminary efficacy of anti-PD-L1 directed therapy with durvalumab (D), durvalumab plus BCG (D + BCG), and durvalumab plus external beam radiation therapy (D + EBRT)., Design, Setting, and Participants: A multicenter phase 1 trial was conducted at community and academic sites., Intervention: Patients received 1120 mg of D intravenously every 3 wk for eight cycles. D + BCG patients also received full-dose intravesical BCG weekly for 6 wk with BCG maintenance recommended. D + EBRT patients received concurrent EBRT (6 Gy × 3 in cycle 1 only)., Outcome Measurements and Statistical Analysis: Post-treatment cystoscopy and urine cytology were performed at 3 and 6 -mo, with bladder biopsies required at the 6-mo evaluation. The recommended phase 2 dose (RP2D) for each regimen was the primary endpoint. Secondary endpoints included toxicity profiles and complete response (CR) rates., Results and Limitations: Twenty-eight patients were treated in the D (n = 3), D + BCG (n = 13), and D + EBRT (n = 12) cohorts. Full-dose D, full-dose BCG, and 6 Gy fractions × 3 were determined as the RP2Ds. One patient (4%) experienced a grade 3 dose limiting toxicity event of autoimmune hepatitis. The 3-mo CR occurred in 64% of all patients and in 33%, 85%, and 50% within the D, D + BCG, and D + EBRT cohorts, respectively. Twelve-month CRs were achieved in 46% of all patients and in 73% of D + BCG and 33% of D + EBRT patients., Conclusions: D combined with intravesical BCG or EBRT proved feasible and safe in BCG-unresponsive NMIBC patients. Encouraging preliminary efficacy justifies further study of combination therapy approaches., Patient Summary: Durvalumab combination therapy can be safely administered to non-muscle-invasive bladder cancer patients with the goal of increasing durable response rates., (Copyright © 2023 European Association of Urology.

Purpose: Partial cystectomy (PC) is a bladder sparing option to treat bladder cancer in a carefully selected group of patients. We sought to analyze outcomes of partial cystectomy (PC) in a contemporary cohort of patients at a single institution., Material and Methods: Records were reviewed for 43 patients with a primary urothelial carcinoma (UC) who had a partial cystectomy with curative intent at Columbia University Medical Center from 2004 to 2019. Endpoints of interest were noninvasive recurrence (defined as any recurrent nonmuscle invasive disease), advanced recurrence (defined as a muscle invasive recurrence or metastasis), and death. We used unadjusted Cox proportional hazards regressions and log rank tests to estimate the association between clinical characteristics and endpoints of interest., Results: Among 43 patients with bladder cancer treated with partial cystectomy, median patient age was 73 years (interquartile range 67-77.5) and 86% were male. Twenty-three percent of patients received preoperative neoadjuvant chemotherapy (NAC) and 49% of patients were given perioperative intravesical chemotherapy at the time of PC. Pathologic stage was

Background: Many patients with recurrent high-risk non-muscle invasive bladder cancer after intravesical bacillus calmette-guerin (BCG) face a difficult decision between radical cystectomy (RC) or salvage intravesical therapy (IVT). We sought to determine if there is a difference in overall survival RC and IVT after previous treatment with BCG., Methods: We performed a retrospective cohort study of patients with Ta, T1, and Tis bladder cancer treated with induction BCG in the SEER-Medicare dataset from 2000 to 2015. We used a proportional hazards regression model to compare differences in survival between patients having RC and IVT. We adjusted for confounding using a propensity score and stratified our analysis according to timing of treatment and stage at diagnosis., Results: We identified 3940 patients who received either IVT (79%) or RC (21%) following induction BCG. Among patients treated within 12 months of BCG, there was no significant difference in survival between RC and IVT (HR 0.92, 95% CI 0.81-1.04) and 17% of patients having early IVT ultimately required RC. Among patients treated at least 12 months after BCG, RC was associated with worse survival than IVT (HR 1.19, 95% CI 1.06-1.35) and 10% of patients having late IVT ultimately required RC., Conclusion: Among patients with bladder cancer who required additional treatments after induction BCG, we did not observe a difference in overall survival between IVT and RC within 12 months of starting BCG. While RC remains the gold-standard for high risk recurrent NMIBC after BCG, bladder preservation with IVT may be appropriate for well-selected patients., (Copyright © 2022 Elsevier Inc.

Objective: To investigate the outcomes of mixed-grade non-muscle invasive bladder cancer (NMIBC) based on the degree of high-grade predominance., Methods: We identified patients in our institutional database who had a transurethral resection of bladder tumor(s) for NMIBC. Tumors with mixed-grade features on pathology report were reanalyzed, assigned the percentage high-grade component, and stratified into ≤ 5% high-grade and > 5% high-grade groups. All others were classified as low-grade or high-grade NMIBC. Differences in recurrence-free survival were assessed by log-rank test. A multivariable Cox regression model was used to evaluate the impact of tumor grade on recurrence, controlling for tumor stage, size, multifocality, and intravesical therapy., Results: Two hundred and twenty patients were followed for a median of 2 years; 127 (58%) had low-grade NMIBC, 66 (30%) had high-grade NMIBC, and 27 (12%) had mixed-grade NMIBC. Of the mixed-grade patients, 14 had a ≤ 5% high-grade component, and 13 had a > 5% high-grade component. Recurrence rates across all groups ranged from 42% to 79%. There was no significant difference in intravesical recurrence-free survival among the grade categories as assessed by log-rank test. On multivariable Cox regression analysis, grade category was not significantly associated with likelihood of recurrence., Conclusions: The prognosis of mixed-grade histology in NMIBC has not previously been well defined. Although grade category was not found to be an independent significant predictor of recurrence, the recurrence rate for mixed-grade tumors was quite high overall. Further studies are required to better understand appropriate risk stratification and treatment of mixed-grade NMIBC., (Copyright © 2021 Elsevier Inc. All rights reserved.)

Objectives: Prior studies have shown that pathologic complete response at radical cystectomy, a significant prognostic factor, can be attributed to both neoadjuvant chemotherapy (NAC) and high-quality transurethral resections (TURBT) prior to NAC. It remains unclear whether the visual completeness of TURBT prior to NAC plays an important role in subsequent outcomes. We sought to assess the association of completeness of TURBT prior to NAC with response and survival outcomes., Methods and Materials: We retrospectively reviewed all patients with clinically localized muscle-invasive bladder cancer at our institution who received NAC from 2000 to 2017. Complete TURBT was defined as resection of all visible tumor in entirety, resection to normal-appearing muscle, and/or repeat pre-NAC TURBT revealing cT0. Patients who were restaged as cT0 after NAC and refused cystectomy were placed on an active surveillance/delayed intervention (ASDI) protocol. The primary endpoints were overall and cancer-specific survival. The secondary endpoints were recurrence-free and muscle-invasive recurrence-free survival., Results: Of 93 patients, 62 (67%) underwent complete TURBT prior to chemotherapy. Compared to patients with incomplete TURBT, those with complete TURBT had lower rates of variant histology (13% vs. 32%) and hydronephrosis (15% vs. 39%). Also, 36% of patients with incomplete TURBT had ≥cT3 disease prior to NAC, compared to none in the complete TURBT cohort. Patients with complete TURBT were more likely to defer RC and pursue ASDI (61% vs. 32%). Those with complete TURBT had lower rates of pT2 or higher disease at cystectomy (48% vs. 75%), with a lower rate of N+ disease trending towards significance (17% vs. 37%). Patients with complete TURBT had higher 5-year overall (77% vs. 46%, P = 0.003) and cancer-specific (85% vs. 50%, P = 0.001) survival. On Cox regression analysis, complete TURBT was significantly associated with superior cancer-specific, recurrence-free, and muscle-invasive recurrence-free survival., Conclusions: A complete TURBT prior to NAC is associated with improved survival and oncologic outcomes in this cohort with muscle-invasive bladder cancer. The extent to which complete TURBT simply represents a proxy for less aggressive disease or is actually a beneficial therapeutic intervention which improves response to chemotherapy is difficult to define retrospectively., (Copyright © 2021 Elsevier Inc.

Objectives: To describe contemporary perioperative outcomes for octogenarians managed under an Enhanced Recovery After Surgery (ERAS) protocol. ERAS protocols have improved outcomes in radical cystectomy (RC), though outcomes for octogenarian patients undergoing RC in the modern ERAS era are not well researched. ERAS components have been gradually implemented into our clinical care pathways over the past 10 years., Methods and Materials: Octogenarians undergoing RC at our institution were retrospectively identified between 2009 and 2019. Cox proportional hazards models examined changes in time to hospital discharge and time to bowel movement over time, and logistic regression models examined differences in 90-day readmissions and discharge dispositions over time. Secondary analyses examined the effect of alvimopan on time to hospital discharge and time to bowel movement using log-rank tests, along with 90-day readmissions and discharge dispositions using Chi-squared tests., Results: Seventy octogenarian patients underwent RC during the study period. Median time to bowel movement was 6 days, while median time to hospital discharge was 9 days. Two-thirds of patients were discharged to home and 22% were readmitted within 90 days. There were no statistically significant associations between year of surgery and perioperative outcomes. Patients taking alvimopan had decreased time to hospital discharge (hazard ratio = 2.7, 95% confidence interval [1.5, 5.0], P = 0.002), but showed no difference in other perioperative outcomes., Conclusions: Octogenarians treated with RC had no significant changes in perioperative outcomes during the implementation of ERAS components at our institution. However, octogenarians taking alvimopan were observed to have decreased time to hospital discharge., (Copyright © 2020 Elsevier Inc. All rights reserved.)

Bladder paragangliomas are rare tumors, with no prospective studies or guidelines on the management of this disease. We present a case series of 6 patients managed with bladder preservation over a median follow-up period of 124 months. We also present a review of the recent literature on bladder paragangliomas. We aim to provide a timely synthesis of the recent evidence on bladder paragangliomas as changing paradigms necessitate individualized treatment., (Copyright © 2020 Elsevier Inc.

Purpose: For patients with bacillus Calmette-Guérin unresponsive or recurrent/relapsing nonmuscle invasive bladder cancer, multi-agent intravesical trials have been limited. In this study we investigate the safety of intravesical cabazitaxel, gemcitabine and cisplatin in the salvage setting., Materials and Methods: This was a dose escalation, drug escalation trial for patients with bacillus Calmette-Guérin unresponsive or recurrent/relapsing nonmuscle invasive bladder cancer who declined or were ineligible for radical cystectomy. All patients underwent a 6-week induction regimen of sequentially administered cabazitaxel, gemcitabine and cisplatin. Complete response was defined as no cancer on post-induction transurethral bladder tumor resection and negative urine cytology, while partial response allowed for positive cytology. Responders continued with maintenance cabazitaxel and gemcitabine monthly for the first year and bimonthly for the second year., Results: A total of 18 patients were enrolled. Mean age was 71 years, median followup was 27.8 months (range 16.3 to 46.9) and mean number of previous rounds of intravesical therapies before trial enrollment was 3.7. Nine patients (50%) had received intravesical chemotherapy after bacillus Calmette-Guérin and 7 (39%) were previously treated in a phase I clinical trial setting. At enrollment 6 (33%) subjects had T1 disease and 13 (72%) had carcinoma in situ. There were no dose limiting toxicities. Initial partial and complete response rates were 94% and 89%, respectively. At 1 year recurrence-free survival was 0.83 (range 0.57 to 0.94) and at 2 years estimated recurrence-free survival was 0.64 (0.32 to 0.84)., Conclusions: In this high risk and highly pretreated cohort of bacillus Calmette-Guérin unresponsive or recurrent/relapsing nonmuscle invasive bladder cancer cases combination intravesical cabazitaxel, gemcitabine and cisplatin was a well tolerated and potentially effective regimen.

Introduction: Over 1,500 bladder cancers were diagnosed among US Veterans in 2010, the majority of which were non-muscle invasive bladder cancer (NMIBC). Little is known about NMIBC treatment within the Veterans Health Administration. The objective of the study was to assess the quality of care for Veterans with newly-diagnosed NMIBC within Veterans Integrated Service Network (VISN) 02., Materials and Methods: We used ICD-9 and ICD-10 codes to identify patients with newly-diagnosed bladder cancer from 1/2016-8/2017. We risk-stratified the patients into low, intermediate, and high-risk based on the 2016 American Urological Association Guidelines on NMIBC. Our primary objectives were percentages of transurethral resection of bladder tumors (TURBTs) with detrusor, repeat TURBT in high-risk and T1 disease, high-risk NMIBC treated with induction intravesical therapy (IVT), and responders treated with maintenance IVT. We performed logistic regression for association between distance to diagnosing hospital and receipt of induction IVT in high-risk patients., Results: There were 121 newly-diagnosed NMIBC patients; 16% low-risk, 28% intermediate-risk, and 56% high-risk. Detrusor was present in 80% of all initial TURBTs and 84% of high-risk patients. Repeat TURBT was performed in 56% of high-risk NMIBC and 60% of T1. Induction IVT was given to 66% of high-risk patients and maintenance IVT was given to 59% of responders. On multivariate logistic regression, distance to medical center was not associated with receipt of induction IVT (OR = 0.99, 95% CI [0.97,1.01], p = 0.52)., Conclusions: We observed high rates of sampling of detrusor in the first TURBT specimen, utilization of repeat TURBT, and administration of induction and maintenance intravesical BCG for high-risk patients among a regional cohort of US Veterans with NMIBC. While not a comparative study, our findings suggest high quality NMIBC care in VA VISN 02., (© Association of Military Surgeons of the United States 2019. All rights reserved.

Background: Bladder cancer is the ninth most common noncutaneous malignancy worldwide, though a fraction (2%-5%) are diagnosed as squamous cell carcinoma (SCC) in the Western world. Current understanding is based on small, single-institution studies and SEER-database reviews with conflicting results. We used the National Cancer Database to explore clinical characteristics and outcomes from a large cohort of invasive bladder SCC., Methods: We queried the National Cancer Database for diagnoses of urothelial carcinoma (UC) or SCC using International Classification of Disease-O-3 morphologic codes from cases reported between 2004 and 2015. Primary outcome was overall survival in cT2-4N0M0 bladder cancer. Statistical analysis performed using chi-squared test, Kaplan-Meier survival, binomial logistic regression, and Cox proportional hazards., Results: The final cohort included 394,979 bladder cancer patients, of which 4,783 (1.2%) were classified as SCC histology. In comparison to UC, patients with SCC were more likely female (49% vs. 24%; P < 0.01) and African American (11% vs. 5%; P < 0.01). Patients with SCC presented at a higher stage than UC with muscle-invasive bladder cancer (MIBC) present at diagnosis in 70% vs. 19%. On multivariate analysis, SCC independently predicted poorer prognosis (hazard-ratio [HR] 1.79, P < 0.01) when controlling for patient characteristics and treatment modality. Unlike UC, there was no benefit with the use of NAC over radical cystectomy alone (HR 0.93, P = 0.69) for patients with SCC., Conclusions: Invasive SCC of the bladder carries a worse prognosis as compared to UC histology, both overall and on a stage-for-stage basis. As opposed to UC, we did not observe a survival benefit for NAC among SCC patients treated with cystectomy., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Objective: To investigate the rate of bladder cancer in patients undergoing cystoscopic evaluation for asymptomatic microscopic hematuria (AMH) in order to identify groups at sufficiently low-risk for bladder cancer in whom invasive testing may be avoided., Methods: We performed a retrospective review of patients who underwent cystoscopic evaluation for AMH between 2010 and 2018. Age, gender, smoking status, history of pelvic radiation, and number of red blood cells per high-power field on urine microscopy were recorded. We used logistic regression to explore the association between specific risk factors and a diagnosis of bladder cancer on cystoscopy., Results: Among the 2118 patients who underwent cystoscopy for AMH, 25 patients (1.2%) were diagnosed with a bladder cancer, all of which were nonmuscle invasive urothelial carcinoma. There were no bladder cancers detected in patients under the age of 50. Older age and positive smoking history were significantly associated with bladder cancer., Conclusion: Bladder cancer was an uncommon finding on cystoscopy among patients being evaluated for AMH, especially in younger patients. We confirmed several known risk factors for bladder cancer, including older age and smoking history. Further studies are required to evaluate the utility of cystoscopy for identifying latent bladder cancers in low-risk patients., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Purpose: To provide a summary of the Third International Consultation on Bladder Cancer recommendations for the management of non-muscle invasive bladder cancer (NMIBC)., Methods: A detailed review of the literature was performed focusing on original articles for the management of NMIBC. An international committee assessed and graded the articles based on the Oxford Centre for Evidence-based Medicine system. The entire spectrum of NMIBC was covered such as prognostic factors of recurrence and progression, risk stratification, staging, management of positive urine cytology with negative white light cystoscopy, indications of bladder and prostatic urethral biopsies, management of Ta low grade (LG) and high risk tumors (Ta high grade [HG], T1, carcinoma in situ [CIS]), impact of BCG strain and host on outcomes, management of complications of intravesical therapy, role of alternative therapies, indications for early cystectomy, surveillance strategies, and new treatments. The working group provides several recommendations on the management of NMIBC., Results: Recommendations were summarized with regard to staging; management of primary and recurrent LG Ta and high risk disease, positive urine cytology with negative white light cystoscopy and prostatic urethral involvement; indications for timely cystectomy; and surveillance strategies., Conclusion: NMIBC remains a common and challenging malignancy to manage. Accurate staging, grading, and risk stratification are critical determinants of the management and outcomes of these patients. Current tools for risk stratification are limited but informative, and should be used in clinical practice when determining diagnosis, surveillance, and treatment of NMIBC.

Purpose: We report the outcomes in patients with muscle invasive bladder cancer from 2 institutions who experienced a clinically complete response to neoadjuvant platinum based chemotherapy and elected active surveillance. It was unknown whether conservative treatment could be safely implemented in these patients., Materials and Methods: We retrospectively reviewed the records of patients with muscle invasive bladder cancer at our institutions who elected surveillance following a clinically complete response to transurethral resection of bladder tumors and neoadjuvant chemotherapy from 2001 to 2017. A clinically complete response was defined as absent tumor on post-chemotherapy transurethral resection of bladder tumor, negative cytology and normal cross-sectional imaging., Results: In the 148 patients followed a median of 55 months (range 5 to 145) the 5-year disease specific, overall, cystectomy-free and recurrence-free survival rates were 90%, 86%, 76% and 64%, respectively. Of the patients 71 (48%) experienced recurrence in the bladder, including 16 (11%) with muscle invasive disease and 55 (37%) with noninvasive disease. Salvage radical cystectomy prevented cancer specific death in 9 of 12 patients (75%) who underwent cystectomy after muscle invasive relapse and in 13 of 14 (93%) after noninvasive relapse., Conclusions: We observed high rates of overall and disease specific survival with bladder preservation in patients who achieved a clinically complete response to neoadjuvant chemotherapy. These outcomes support the safety of active surveillance in carefully selected, closely monitored patients with muscle invasive bladder cancer. Future studies should aim to improve patient selection by identifying biomarkers predicting invasive relapse and developing novel imaging methods of early detection., (Copyright © 2018 American Urological Association Education and Research, Inc.

Bladder cancer is the fifth most prevalent cancer in the U.S., yet is understudied, and few laboratory models exist that reflect the biology of the human disease. Here, we describe a biobank of patient-derived organoid lines that recapitulates the histopathological and molecular diversity of human bladder cancer. Organoid lines can be established efficiently from patient biopsies acquired before and after disease recurrence and are interconvertible with orthotopic xenografts. Notably, organoid lines often retain parental tumor heterogeneity and exhibit a spectrum of genomic changes that are consistent with tumor evolution in culture. Analyses of drug response using bladder tumor organoids show partial correlations with mutational profiles, as well as changes associated with treatment resistance, and specific responses can be validated using xenografts in vivo. Our studies indicate that patient-derived bladder tumor organoids represent a faithful model system for studying tumor evolution and treatment response in the context of precision cancer medicine., (Copyright © 2018 Elsevier Inc.

Purpose: Radical cystectomy (RC) has become increasingly regionalized to high-volume hospitals. Our objective was to describe changes in regional market concentration and the distribution of RCs among hospitals, and examine how these changes affect patient travel distance to surgery., Materials and Methods: We used the surveillance, epidemiology, and end results-Medicare database to identify patients who had RC for bladder cancer from 2001 to 2011. We defined RC market concentration within each Hospital Referral Regions (HRR) in surveillance, epidemiology, and end results using the Hirschman-Herfindhal Index. We measured straight-line patient travel distance to the nearest cystectomy provider hospital and used linear regression to evaluate the effect of market concentration on travel distance for surgery. We performed a similar analysis on patients who had laparoscopic cholecystectomy as a comparator., Results: We identified 10,802 patients with bladder cancer who had RC. From 2001 to 2011, 40% of HRRs had a statistically significant increase in Hirschman-Herfindhal Index, 53% had no significant change and 7% had a statically significant decrease. The median patient travel distance increased significantly from 10.4 miles (interquartile range: 2.6-30.2) to 16 miles (interquartile range: 6.3-40.4, P<0.0001). Patients who lived in a highly concentrated HRR had to travel significantly further than patients who lived in an unconcentrated HRR (β = 37.5, P<0.001). These trends were not seen for laparoscopic cholecystectomy., Conclusions: Between 2001 and 2011, RC became increasingly regionalized to a small group of hospitals with a resultant increase in regional RC market concentration and patient travel distance. The clinical consequences on these changes to patients who require RC are uncertain., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: We sought to determine if idiographic, or self-defined, measures added to our understanding of patients with bladder cancer's quality of life (QOL) prior to radical cystectomy (RC). We tested whether idiographic measures increased prediction of global QOL beyond standard (nomothetic) measures of QOL components., Methods: We administered the European Organization for Research and Treatment of Cancer Quality of Life Questionnaires (QLQ)-C30 and QLQ-BLM30, and our own idiographic Quality of Life Appraisal Profile prior to RC. Idiographic measures included number of goal statements, distance from goal attainment, and ability to complete goal attainment activities. Multivariate linear regression was used to predict measures of global QOL and related constructs of life satisfaction and mental health., Results: Two hundred fiftheen patients reported a median of 8 (interquartile range [IQR] 6, 11) goals and half had an average goal attainment rating above 6.9 out of 10 (IQR 5.5, 8.2). On multivariable analysis, QLQ-C30 role functioning and QLQ-BLM30 future perspective explained 15.7% of the variability in preoperative global QOL. Including goal attainment and activity difficulty explained an additional 12% of global QOL variance. Smaller gains were seen on measures of global health, life satisfaction, mental health, and activity, suggesting that idiographic measures capture aspects of QOL distinct from health and functional status defined by nomothetic scales., Conclusions: Idiographic assessment of QOL added to prediction of global QOL above and beyond health-related components measured using nomothetic instruments. This self-defined information may be valuable in communicating with cancer patients about their QOL. Copyright © 2015 John Wiley & Sons, Ltd., (Copyright © 2015 John Wiley & Sons, Ltd.)

Purpose: We determined the extent to which complications as well as number of hospital-free days within 30 and 90 days of surgery predicted health related quality of life 1 year after radical cystectomy., Materials and Methods: We used data from a prospective health related quality of life study using a validated instrument, the Vanderbilt Cystectomy Index-15. Complications were graded by the Clavien system, and hospital length of stay and length of stay during readmissions were used to calculate 30 and 90-day hospital-free days, respectively. We compared the number of hospital-free days among patients with varying levels of complications. Multivariate analysis was performed to determine predictors of Vanderbilt Cystectomy Index-15 score 1 year after surgery adjusting for demographic (age, gender, comorbidities) and clinical variables (stage and diversion type)., Results: A total of 100 patients with complete baseline and 1-year followup health related quality of life data were included in the analysis. Median (IQR) 30 and 90-day hospital-free days were 24 (22-25) and 84 (82-85), respectively. Patients who experienced any complications had significantly fewer 30-day hospital-free days (22 vs 24 days, p <0.01) and 90-day hospital-free days (81 vs 84 days, p <0.01), and patients with higher grade complications had fewer hospital-free days than those with lower grade or no complications (p <0.01). On multivariate analysis female gender and baseline Vanderbilt Cystectomy Index-15 score independently predicted higher 1-year health related quality of life scores., Conclusions: Patients who experience complications after radical cystectomy have fewer 30 and 90-day hospital-free days. However, neither predicts health related quality of life at 1 year. Instead, long-term health related quality of life appears to be driven largely by baseline health related quality of life and gender., (Copyright © 2014 American Urological Association Education and Research, Inc.

Background: Differences in quality of care may contribute to racial variation in outcomes of bladder cancer (BCa). Quality indicators in patients undergoing surgery for BCa include the use of high-volume surgeons and high-volume hospitals, and, when clinically indicated, receipt of pelvic lymphadenectomy, receipt of continent urinary diversion, and undergoing radical cystectomy instead of partial cystectomy. The authors compared these quality indicators as well as adverse perioperative outcomes in black patients and white patients with BCa., Methods: The Healthcare Cost and Utilization Project State Inpatient Databases for New York, Florida, and Maryland (1996-2009) were used, because they consistently included race, surgeon, and hospital identifiers. Quality indicators were compared across racial groups using regression models adjusting for age, sex, Elixhauser comorbidity sum, insurance, state, and year of surgery, accounting for clustering within hospital., Results: Black patients were treated more often by lower volume surgeons and hospitals, they had significantly lower receipt of pelvic lymphadenectomy and continent diversion, and they experienced higher rates of adverse outcomes compared with white patients. These associations remained significant for black patients who received treatment from surgeons and at hospitals in the top volume decile., Conclusions: Black patients with BCa had lower use of experienced providers and institutions for BCa surgery. In addition, the quality of care for black patients was lower than that for whites even if they received treatment in a high-volume setting. This gap in quality of care requires further investigation., (© 2013 American Cancer Society.)

Purpose: Most long-term morbidity after radical cystectomy is related to the urinary diversion or reconstruction. While there are benefits to an orthotopic neobladder, there can be a substantial risk of voiding dysfunction in women. We examine the prevalence of postoperative voiding complications in women who underwent orthotopic neobladder diversion., Materials and Methods: We identified all women who underwent radical cystectomy and orthotopic neobladder for bladder cancer at our institution from 1996 to 2011 (51) and included patients with regular clinic followup (49). The presence and severity of incontinence and hypercontinence were evaluated at routine clinic visits. Unadjusted analyses were performed to measure the association between patient variables and voiding symptoms, with p < 0.05 considered significant., Results: Daytime incontinence, nighttime incontinence and hypercontinence were reported by 43%, 55% and 31% of women, respectively. A neobladder-vaginal fistula developed in 3 women (6%). On unadjusted analysis having daytime incontinence was associated with a concurrent or previous hysterectomy (p = 0.031), but not with age, disease stage, preoperative incontinence, year of surgery or sparing the vaginal wall. The severity of daytime incontinence was associated with preoperative incontinence only (p = 0.02). The presence and severity of nighttime incontinence were associated with patient age only (p = 0.013, p = 0.005, respectively). Hypercontinence was not associated with any variable., Conclusions: Among women with orthotopic neobladder after radical cystectomy we identified a significant prevalence of voiding dysfunction. We recommend preoperative discussion of these possible complications with any woman interested in orthotopic neobladder to establish realistic expectations. For properly selected women who understand these risks, orthotopic neobladder may be an appropriate diversion choice., (Copyright © 2012 American Urological Association Education and Research, Inc.

Objective: Radical cystectomy (RC) for bladder cancer can be associated with significant morbidity and alterations in health-related quality of life (HRQOL). The Functional Assessment of Cancer Therapy--Vanderbilt Cystectomy Index (FACT-VCI) is a condition-specific HRQOL survey for patients undergoing RC and urinary diversion (UD) for bladder cancer. This study evaluates the reliability, validity, and responsiveness of the Vanderbilt cystectomy index (VCI)., Methods: The FACT-VCI was administered to patients with bladder cancer undergoing RC and UD (n = 190) at 2 major cancer centers. Statistical methods included principal components analysis, Cronbach's coefficient alpha, and nonparametric correlation coefficients. The Functional Assessment of Cancer Therapy--General (FACT-G) was used to test criterion-related validity and a linear mixed model tested the effects of time and diversion type on longitudinal VCI scores., Results: A single summary score of 15 gender-neutral items (VCI-15) represented the optimum solution for postoperative data, which was internally consistent (α = 0.85), had strong retest reliability (ρ = 0.891), and was associated with all FACT-G scales and total score (ρ ≥ 0.38, P <.001). Preoperatively, the VCI-15 was internally consistent (α = 0.77) and was associated with the FACT-G physical and functional scales and total score (ρ ≥ 0.41, P <.001). Although VCI-15 scores at postoperative year 1 did not differ from preoperative values overall (P = .145), they did differ by diversion type (P = .027), with no substantive change after orthotopic neobladder (40 ± 9 vs 39 ± 10) but with a clinically significant improvement after an ileal conduit (39 ± 11 vs 44 ± 11)., Conclusion: The VCI-15 is a reliable and valid condition-specific HRQOL survey for patients with bladder cancer undergoing RC and UD. Future studies of RC patients should measure HRQOL using validated, condition-specific forms, such as the FACT-VCI., (Copyright © 2012 Elsevier Inc. All rights reserved.)

Purpose: The American Urological Association guideline for asymptomatic microhematuria recommends in patients with a negative initial workup, repeat workup should be considered for those with persistent/recurrent microhematuria. However, there is little data on the yield of repeat evaluation. Our hypothesis was that repeat workup yields a low detection rate of urologic malignancy.Materials and Methods: We retrospectively reviewed all patients at our institution who underwent microhematuria workup with cystoscopy and upper tract imaging from May 2010 to June 2016. Microhematuria was defined as ≥3 RBCs/HPF on a properly collected specimen in the absence of a benign cause. Demographics, age, smoking history, history of radiation, and findings on repeat cystoscopy and imaging were collected. Our primary endpoint was a new diagnosis of urologic malignancy.Results: Our initial cohort included 1,332 patients, of whom 21 were diagnosed with urothelial carcinoma and 7 with suspicious renal masses on initial workup. A total of 637 patients with negative initial workup had persistent/recurrent microhematuria. Repeat cystoscopy was performed in 161 (25%) patients at a median of 39 months, and repeat upper tract imaging was performed in 317 (50%) patients at a median of 39 months. Overall, repeat cystoscopy revealed new bladder cancer in 2 (1.2%) patients and repeat imaging revealed new suspicious renal mass in 4 (1.3%) patients.Conclusions: We observed a low number of newly diagnosed malignancies among patients with persistent/recurrent asymptomatic microhematuria who had a prior negative workup. Additional research is required to determine the utility of a repeat AMH workup. [ABSTRACT FROM AUTHOR]
