Abstract
OBJECTIVE To describe patient characteristics and pathological stage at bladder cancer (BCa) diagnosis in a diverse population within a national, equal-access healthcare system. METHODS This retrospective cohort study identified 15 966 men diagnosed with BCa in the Veterans Affairs (VA) healthcare system from 2000 to 2020. The primary outcome was pathological stage at diagnosis, determined by index transurethral resection of bladder tumour. Logistic regression was used to assess the relationship between race and stage. Competing risk models tested the association between race and BCa-specific mortality with cumulative incidence estimates. RESULTS Of 15 966 BCa patients, 12 868 (81%), 1726 (11%), 493 (3%) and 879 (6%) were White, Black, Hispanic and Other race, respectively. Black patients had significantly higher muscle-invasive bladder cancer (MIBC) rates than White patients (35% vs 32%; P = 0.009). In multivariable analysis, the odds of presenting with MIBC did not differ significantly between Black and White patients (odds ratio [OR] 1.10, 95% confidence interval [CI] 0.98-1.22) or between Hispanic patients (OR 0.82, 95% CI 0.67-1.01) and White patients. Compared to White patients, Black patients had a similar risk of BCa-specific mortality (hazard ratio [HR] 0.89, 95% CI 0.75-1.06), whereas Hispanic patients had a lower risk (HR 0.56, 95% CI 0.38-0.82). CONCLUSIONS Black patients presented with the highest rates of de novo MIBC. However, in a large, equal-access healthcare system, this did not result in a difference in BCa-specific mortality. In contrast, Hispanic patients had lower risks of MIBC and BCa-specific mortality.

Abstract
BACKGROUND Population-based studies evaluating outcomes for metastatic upper tract urothelial carcinoma (mUTUC) are sparse and rarely capture both patients with de novo (synchronous) metastases and those who progress to metastatic disease (metachronous). Herein we evaluated the outcomes and costs associated with synchronous and metachronous mUTUC, utilizing a novel Methodology. Additionally, we created a guideline-based quality score to improve care in this space. PATIENTS AND METHODS We identified all patients with mUTUC aged 66 years and older included in the SEER-Medicare linked database between 2004 and 2012. Achievement of 3 quality criteria was assessed: (1) cancer-specific survival (CSS)>12 months; (2) receipt of systemic therapy; (3) receipt of hospice/palliative care. Total healthcare and out-of-pocket costs were evaluated. Regression analyses were performed to assess characteristics associated with quality criteria and total healthcare costs. RESULTS Of the 1223 patients identified, at least one quality criterion was met in just 40.2% and only 54 patients (4.4%) received palliative care. In multivariable analysis, patients with synchronous mUTUC (OR:0.55, 95%CI:0.41-0.72), and at least 3 comorbidities (OR:0.68, 95%CI:0.47-0.98) were less likely to achieve at least 1 quality criterion. Meeting at least 1 quality criterion was associated with increased costs ($94,677, 95%CI:87,702-101,652 versus $63,575, 95%CI:59,598-67,552). CONCLUSIONS Less than half of patients with mUTUC met at least 1 quality criterion. Quality score achievement was associated with a modest increase in total healthcare spending. These findings not only provide guidance for future study of rare diseases using secondary data, but also highlight inadequacies in the current management of mUTUC.

Abstract
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.

Abstract
BACKGROUND Age disparity in patients with non-muscle-invasive bladder cancer (NMIBC) exists. Whether this is due to differences in adequate cancer care or tumour biology is unclear. OBJECTIVE To investigate age disparities in NMIBC using the Surveillance, Epidemiology, and End Results (SEER)-Medicare and UROMOL datasets. DESIGN, SETTING, AND PARTICIPANTS The SEER-Medicare data were used to identify patients with clinical stage Ta, Tis, and T1 NMIBC between 2005 and 2017 (n = 32 225). Using the UROMOL cohort (n = 834), age disparities across transcriptomic, genomic, and spatial proteomic domains were assessed. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS For the SEER-Medicare data, multivariable competing-risk regression was used to examine the association between age and recurrence, progression, and bladder cancer-specific mortality (BCSM). For the UROMOL cohort, multivariable general linear model and multinomial logistic regression were performed to evaluate the association between age and tumour biology. RESULTS AND LIMITATIONS An analysis of the SEER-Medicare cohort revealed 5-yr recurrence rates of 55.2%, 57.4%, and 58.9%; 5-yr progression rates of 25.6%, 29.2%, and 36.9%; and 5-yr BCSM rates of 3.9%, 5.8%, and 11.8% in patients aged 66-70, 71-80, and ≥81 yr, respectively. After multivariable adjustment, age ≥81 yr was associated with a higher risk of recurrence (hazard ratio [HR] 1.07, 95% confidence interval [CI] 1.03-1.12; p = 0.001), progression (HR 1.32, p < 0.001), and BCSM (HR 2.58, p < 0.001). UROMOL2021 transcriptomic class 2a was most frequently observed in patients with advanced age (34.0% in ≥76 yr vs 21.6% in ≤65 yr; p = 0.004), a finding confirmed on multivariable analysis (risk ratio [RR] 3.86, p = 0.002). UROMOL2021 genomic class 3 was observed more frequently in patients aged ≥76 yr (4.9% vs 24.2%; p = 0.001). Limitations include the definitions used for recurrence and progression, which may lead to under- or overestimation of true rates. CONCLUSIONS Among SEER-Medicare patients with NMIBC, advanced age is associated with inferior oncological outcomes. These results reflect age-related molecular biological differences observed across transcriptomic and genomic domains, providing further evidence that innate tumour biology contributes to observed disparities in NMIBC outcomes. PATIENT SUMMARY Older patients with non-muscle-invasive bladder cancer have worse oncological outcomes than younger patients. Some of this age disparity may be due to differences in tumour biology.

Abstract
INTRODUCTION Prior studies suggest that white light cystoscopy (WLC) alone can fail to detect cases of non-muscle invasive bladder cancer (NMIBC) vs. blue light cystoscopy (BLC). We describe bladder cancer outcomes and the impact of BLC among NMIBC patients in an equal access setting. MATERIALS AND METHODS We assessed 378 NMIBC patients within the Veterans Affairs system that had a CPT code for BLC from December 1, 2014 to December 31, 2020. We determined recurrence rates and time to recurrence prior to BLC (ie, after previous WLC if available) and following BLC. We used the Kaplan-Meier method to estimate event-free survival and Cox regression to determine association between BLC and recurrence, progression, and overall survival; and further, whether these outcomes differed by race. RESULTS Of 378 patients with complete data, 43 (11%) were Black and 300 (79%) White. Median follow-up was 40.7 months from bladder cancer diagnosis. Median time to first recurrence following BLC was longer vs. WLC alone (40 [33-NE] vs. 26 [17-39] months). Recurrence risk was significantly lower following BLC (Hazard Ratio [HR] 0.70; 95% Confidence Interval [CI], 0.54-0.90). There was no significant difference in recurrence (HR 0.69; 95% CI, 0.39-1.20), progression (HR 1.13; 95% CI, 0.32-3.96), and overall survival (HR 0.74; 95% CI, 0.31-1.77) following BLC by Black vs. White race. CONCLUSION In this study from an equal access setting in the VA, we observed significantly decreased recurrence risk and prolonged time interval to recurrence following BLC vs. WLC alone. There was no difference in bladder cancer outcomes by race.

Abstract
CONTEXT Differences in recovery, oncological, and quality of life (QoL) outcomes between open radical cystectomy (ORC) and robot-assisted radical cystectomy (RARC) for patients with bladder cancer are unclear. OBJECTIVE This review aims to compare these outcomes within randomized trials of ORC and RARC in this context. The primary outcome was the rate of 90-d perioperative events. The secondary outcomes included operative, pathological, survival, and health-related QoL (HRQoL) measures. EVIDENCE ACQUISITION Systematic literature searches of MEDLINE, Embase, Web of Science, and clinicaltrials.gov were performed up to May 31, 2022. EVIDENCE SYNTHESIS Eight trials, reporting 1024 participants, were included. RARC was associated with a shorter hospital length of stay (LOS; mean difference [MD] 0.21, 95% confidence interval [CI] 0.03-0.39, p = 0.02) than and similar complication rates to ORC. ORC was associated with higher thromboembolic events (odds ratio [OR] 1.84, 95% CI 1.02-3.31, p = 0.04). ORC was associated with more blood loss (MD 322 ml, 95% CI 193-450, p < 0.001) and transfusions (OR 2.35, 95% CI 1.65-3.36, p < 0.001), but shorter operative time (MD 76 min, 95% CI 39-112, p < 0.001) than RARC. No differences in lymph node yield (MD 1.07, 95% CI -1.73 to 3.86, p = 0.5) or positive surgical margin rates (OR 0.95, 95% CI 0.54-1.67, p = 0.9) were present. RARC was associated with better physical functioning or well-being (standardized MD 0.47, 95% CI 0.29-0.65, p < 0.001) and role functioning (MD 8.8, 95% CI 2.4-15.1, p = 0.007), but no improvement in overall HRQoL. No differences in progression-free survival or overall survival were seen. Limitations may include a lack of generalization given trial patients. CONCLUSIONS RARC offers various perioperative benefits over ORC. It may be more suitable in patients wishing to avoid blood transfusion, those wanting a shorter LOS, or those at a high risk of thromboembolic events. PATIENT SUMMARY This study compares robot-assisted keyhole surgery with open surgery for bladder cancer. The robot-assisted approach offered less blood loss, shorter hospital stays, and fewer blood clots. No other differences were seen.

Abstract
OBJECTIVE This analysis seeks to understand variables within our institution that impact pain management agreement (PMA) utilization for chronic noncancer pain (CNCP). DESIGN Retrospective chart review. SETTING Public academic medical center. PATIENTS Adults prescribed an opioid for CNCP between July 2020 and October 2020. MAIN OUTCOME MEASURE We assessed the association between patient demographics, prescription factors, and prescriber factors with the presence of a PMA. Unadjusted rates and chi-square tests were generated for each predictor. Additionally, we performed two multivariable logistic regressions: one including all variables and another utilizing a stepwise forward variable selection process to further understand the relationships between predictors and the presence of a PMA. RESULTS 49.7 percent of patients who received an opioid for CNCP had a PMA on file. One significant predictor of the presence of PMA was prescriber specialty with anesthesia/pain medicine, demonstrating 88 percent compliance. Compared to anesthesia/pain medicine, patients receiving opioids from internal medicine had an odds ratio (OR) of 0.155 (95 percent confidence interval (CI), 0.109-0.220), while patients receiving opioids from family medicine had an OR of 0.122 (95 percent CI, 0.090-0.167). Additionally, patients who received schedule II opioids (as opposed to schedule III/IV opioids), patients with multiple opioid fills in 3 months, middle aged patients, and Black patients were more likely to have a PMA. CONCLUSIONS Compliance with PMA within our institution was only 49 percent despite an existing state law mandating use. Our analysis suggests quality improvement interventions should target patients on schedule III/IV opioids who receive their prescriptions from primary care providers.

Abstract
The morbidity associated with radical cystectomy (RC) for muscle-invasive bladder cancer (MIBC) has fueled investigations into the feasibility of bladder preservation strategies after a favorable clinical response to neoadjuvant therapy (NAT). Identifying optimal candidates for bladder preservation is predicated on our ability to identify tumors with inherent cisplatin sensitivity and accurately stage patients before and after NAT. In the present review, we evaluate the accuracy and limitations of contemporary staging modalities and investigate clinical outcomes in patients with MIBC who were managed with bladder preservation after NAT. Lastly, we discuss the predictive role of cisplatin-sensitizing DNA damage response (DDR) gene alterations as a foundational component to current prospective clinical trials evaluating bladder preservation in the setting of MIBC.

Abstract
The authors prospectively evaluated the implementation of a prespecified protocol to eliminate post-discharge opioid prescription after major urologic cancer surgery at a single center among a predominantly opioid naïve population. The intervention included both provider and patient education along with a standardized regimen for non-opioid analgesia during the inpatient stay and after discharge. Use of a standardized protocol nearly eliminated opioid prescriptions after major urologic cancer surgery without adversely impacting patient reported pain control and satisfaction, unplanned visits, and complications.

Abstract
Importance To date, limited data exist regarding the association between Agent Orange and bladder cancer, and the Institute of Medicine concluded that the association between exposure to Agent Orange and bladder cancer outcomes is an area of needed research. Objective To examine the association between bladder cancer risk and exposure to Agent Orange among male Vietnam veterans. Design, Setting, and Participants This nationwide Veterans Affairs (VA) retrospective cohort study assesses the association between exposure to Agent Orange and bladder cancer risk among 2 517 926 male Vietnam veterans treated in the VA Health System nationwide from January 1, 2001, to December 31, 2019. Statistical analysis was performed from December 14, 2021, to May 3, 2023. Exposure Agent Orange. Main Outcomes and Measures Veterans exposed to Agent Orange were matched in a 1:3 ratio to unexposed veterans on age, race and ethnicity, military branch, and year of service entry. Risk of bladder cancer was measured by incidence. Aggressiveness of bladder cancer was measured by muscle-invasion status using natural language processing. Results Among the 2 517 926 male veterans (median age at VA entry, 60.0 years [IQR, 56.0-64.0 years]) who met inclusion criteria, there were 629 907 veterans (25.0%) with Agent Orange exposure and 1 888 019 matched veterans (75.0%) without Agent Orange exposure. Agent Orange exposure was associated with a significantly increased risk of bladder cancer, although the association was very slight (hazard ratio [HR], 1.04; 95% CI, 1.02-1.06). When stratified by median age at VA entry, Agent Orange was not associated with bladder cancer risk among veterans older than the median age but was associated with increased bladder cancer risk among veterans younger than the median age (HR, 1.07; 95% CI, 1.04-1.10). Among veterans with a diagnosis of bladder cancer, Agent Orange was associated with lower odds of muscle-invasive bladder cancer (odds ratio [OR], 0.91; 95% CI, 0.85-0.98). Conclusions and Relevance In this cohort study among male Vietnam veterans, there was a modestly increased risk of bladder cancer-but not aggressiveness of bladder cancer-among those exposed to Agent Orange. These findings suggest an association between Agent Orange exposure and bladder cancer, although the clinical relevance of this was unclear.

Abstract
Bladder cancer remains one of the costliest malignancies to manage. We provide a narrative review of literature assessing the economic burden and cost-effectiveness of bladder cancer treatment and surveillance. This is an update to a previous review and focuses on data published within the past 10 years. We queried PubMed and MEDLINE for all bladder cancer cost-related literature between 2013 and 2023. After initial screening, 117 abstracts were identified, 50 of which were selected for inclusion in our review. Management of disease recurrence and treatment complications contributes significantly to the high cost of care. High-value interventions are therefore treatments that improve recurrence-free and overall survival at minimal additional toxicity. De-escalation of surveillance and diagnostic interventions may help to reduce costs in this space without compromising oncologic control. The persistently rising cost of novel cancer drugs undermines their value when only modest gains in efficacy are observed. Multiple cost-effectiveness analyses have been published and are useful for contextualizing the cost, efficacy, and impact on quality of life that interventions have in this population. Further cost-effectiveness work is needed to better characterize the impact that treatment costs have on patients' financial well-being and quality of life.

Abstract
482 Background: Population-based studies evaluating outcomes exclusively for metastatic upper tract urothelial carcinoma (mUTUC) are sparse and often only capture patients with de novo (synchronous) metastases as opposed to those who progress to metastatic disease (metachronous). We sought to evaluate the outcomes and costs associated with mUTUC and employ a novel methodology to identify both synchronous and metachronous mUTUC patients using claims data. Additionally, we created a guideline-based quality score to improve quality of care in this space. Methods: Using the SEER-Medicare database we identified patients aged 66 years and older diagnosed with mUTUC between 2004 and 2012. Achievement of the following quality criteria was assessed: 1) cancer-specific survival greater than 12 months; 2) receipt of systemic therapy; 3) receipt of hospice/palliative care. Kaplan-Meier survival curves and Cox proportional hazard models were used to compare overall survival between quality scores (0 vs. ≥1) and synchronous vs. metachronous mUTUC. Total healthcare and Medicare Part D out-of-pocket costs within two years of diagnosis were evaluated. Regression analyses were performed to assess characteristics associated with quality criteria and total healthcare costs. Results: Of the 1,223 patients identified, 381 (31.2%) and 842 (68.8%) had synchronous and metachronous mUTUC, respectively. At least one quality criterion was met in 40.2% of patients. Notably, only 54 patients (4.4%) received palliative care services. On multivariable analysis, patients with synchronous mUTUC (OR:0.55, 95%CI:0.41–0.72), and at least 3 comorbidities (OR:0.68, 95%CI:0.47–0.98), were less likely to achieve at least one quality criterion. Patients meeting quality criteria had longer survival compared with patients who did not meet criteria (HR:0.52, 95%CI: 0.46–0.59). Meeting at least one quality criterion was independently associated with increased costs ($94,677, 95%CI: 87702–101652 vs. $63575, 95%CI: 59598–67552) on multivariable regression analysis. Conclusions: Less than half of mUTUC patients met at least one quality criterion. Quality score achievement was associated with longer overall survival at a modest increase in total healthcare spending. These findings not only provide guidance for future study of rare diseases using secondary data, but also highlight inadequacies in the current management of mUTUC.

Abstract
461 Background: Prior studies suggest that white light cystoscopy (WLC) alone can fail to detect cases of non-muscle invasive bladder cancer (NMIBC) compared to blue light cystoscopy (BLC). We describe bladder cancer outcomes and the impact of BLC among NMIBC patients in an equal access setting. Methods: A total of 378 NMIBC patients within the Veterans Affairs system that had a CPT code for BLC from December 1, 2014 to December 31, 2020 were assessed. We determined recurrence rates and time to recurrence prior to BLC (i.e. after previous WLC if available) and following BLC. We used the Kaplan-Meier method to estimate event-free survival and Cox regression to determine the association between race and recurrence, progression, and overall survival. Results: Of 378 patients with complete data, 43 (11%) were Black and 300 (79%) White. Median follow-up was 40.7 months from bladder cancer diagnosis. There were 194 (51%) patients with either TaHG or T1 without CIS; 52 (14%) had CIS with or without TaHG or T1; and 127 (34%) had TaLG only. A total of 239 (63%) patients received BCG at any point during the study. Median time to first recurrence following BLC was longer compared to WLC alone (40 (33-NE) vs. 26 (17-39) months). The risk of recurrence was significantly lower following BLC (Hazard Ratio (HR) 0.70; 95% Confidence Interval (CI) 0.54-0.90). There was no significant difference in recurrence (Hazard Ratio (HR) 0.83; 95% Confidence Interval (CI) 0.48-1.43), progression (HR 1.46; 95% CI 0.45-4.74), and overall survival (HR 0.69; 95% CI 0.29-1.65) following BLC by Black vs. White race. Conclusions: In this study from an equal access setting in the VA, we observed significantly decreased risk of recurrence and prolonged time interval to recurrence following BLC compared to WLC alone. There was no difference in any bladder cancer outcomes by race.

Abstract
INTRODUCTION Muscle-invasive bladder cancer (BC) often occurs in patients with competing mortality risks, while also being associated with the highest rate of second primary nonurothelial cancers (SNUC) of all solid malignancies. We investigated the incidence, risk factors, and timing of SNUC as a competing mortality risk factor in patients with BC who were treated with curative intent radical cystectomy (RC). METHODS We performed a retrospective cohort study assessing patients who underwent RC for cT2-4 N0M0 BC from January 1, 2005 to December 31, 2018 at a single, high volume tertiary care referral center. The Fine-Gray multivariable regression model was used to evaluate predictive factors for SNUC. Cumulative incidence of mortality (CIM) was estimated with modified Kaplan-Meier analysis. RESULTS The median follow-up time for the 693 patients who underwent RC was 3.7 years (interquartile range [IQR] 1.9-5.9 years). SNUC developed in 85 (12.3%) patients at a median 3.0 years post-RC (IQR 1.2-5.5 years). On multivariable analysis, the only significant predictor for developing SNUC was freedom from BC recurrence or metastasis (HR 1.54, 95% CI 1.12-1.76, P = 0.019). The most common SNUCs were primary lung cancer (24, 3.2% of cohort) and colon cancer (9, 1.3% of cohort). BC surveillance imaging diagnosed SNUC in 35/52 (67.3%) patients with solid-organ visceral primaries. The overall mortality rate for any SNUC was 38.8%, with the 3 most lethal cancer types being pancreatic, lung, and colon (62.5%, 54.2%, and 44.4% mortality, respectively). The incidence of SNUC uniformly increased postoperatively, with a cumulative incidence of 22.1% (95% CI, 16.8-27.9%) at 12-years post-RC. 163 patients (23.5%) died from BC, 33 patients (4.8%) died from SNUC, and 94 patients (13.6%) died from other causes. While the CIM for BC plateaued around 5-years post-RC at 24%, the incidence of other-cause mortality uniformly rose throughout the postoperative period. By post-RC year 9 there was no significant difference in CIM between BC (CIM 27.2%, 95% CI, 23.5-31.1%) and other-causes (CIM 20.0%, 95% CI, 15.8-24.6%). CONCLUSIONS The cumulative incidence of SNUC at 12-years post-RC was 22%, with the majority identified on BC surveillance imaging. While BC mortality plateaued around 5-years post-RC, mortality related to SNUC or other causes rose steadily in the postoperative period. These data have clinical significance with regards to patient counseling, survivorship and oncologic surveillance in the highly comorbid muscle-invasive BC population.

Abstract
CONTEXT Patients undergoing radical cystectomy frequently suffer from infectious complications, including urinary tract infections (UTIs) and surgical site infections (SSIs) leading to emergency department visits, hospital readmission, and added cost. OBJECTIVE To summarize the literature regarding perioperative antibiotic prophylaxis, ureteric stent usage, and prevalence of infectious complications after cystectomy. EVIDENCE ACQUISITION A systematic review of PubMed/Medline, EMBASE, Cochrane Library, and reference lists was conducted. EVIDENCE SYNTHESIS We identified 20 reports including a total of 55 306 patients. The median rates of any infection, UTIs, SSIs, and bacteremia were 40%, 20%, 11%, and 6%, respectively. Perioperative antibiotic prophylaxis differed substantially between reports. Perioperative antibiotics were used only during surgery in one study but were continued over several days after surgery in all other studies. Empirical use of antibiotics for 1-3 d after surgery was described in 12 studies, 3-10 d in two studies, and >10 d in four studies. Time to stent removal ranged from 4 to 25 d after cystectomy. Prophylactic antibiotics were used before stent removal in nine of 20 studies; two of these studies used targeted antibiotics based on urine cultures from the ureteric stents, and the other seven studies used a single shot or 2 d of empirical antibiotics. Studies with any prophylactic antibiotic before stent removal found a lower median percentage of positive blood cultures after stent removal than studies without prophylactic antibiotics before stent removal (2% vs 9%). CONCLUSIONS We confirmed a high proportion of infectious complications after cystectomy, and a heterogeneous pattern of choice and duration of antibiotics during and after surgery or stent removal. These findings highlight a need for further studies and support quality prospective trials. PATIENT SUMMARY In this review, we observed wide variability in the use of antibiotics before or after surgical removal of the bladder.

Abstract
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.

Abstract
BACKGROUND To examine differences in survival outcomes for muscle-invasive bladder cancer patients stratified by new mental health diagnosis. METHODS Using the Surveillance, Epidemiology, and End Results (SEER)-Medicare data, we identified patients diagnosed with muscle-invasive bladder cancer between 2008 and 2014. Our primary outcome was cancer-specific and overall hazards of mortality. As a secondary outcome, we reported predictors of developing a new mental health diagnosis after bladder cancer diagnosis. We used Cox proportional hazards models to determine the impact of palliative care and mental health diagnoses on survival outcomes after adjusting for grade, stage, comorbidity index, and baseline demographics. RESULTS Of the 3794 patients who met inclusion criteria, 1193 (31%) were diagnosed with a mental health illness after their bladder cancer diagnosis during the 6 years in the study period. The most common diagnoses were depression (13%), alcohol and drug abuse (12%), and anxiety (11%). Patients with a post-bladder cancer mental health diagnosis had a 57% higher hazard of overall mortality (HR 1.57, P = .048) and an 80% higher hazard of bladder cancer-specific mortality (HR 1.81, P = .037) CONCLUSIONS: New mental health diagnoses are associated with worse survival in patients with muscle invasive bladder cancer. This suggests that a multimodal approach to bladder cancer treatment should include addressing the non-oncologic needs of the patient to optimize survival outcomes.

Abstract
CONTEXT Intermediate-risk (IR) non-muscle-invasive bladder cancer (NMIBC) is a heterogeneous disease. OBJECTIVE To update the International Bladder Cancer Group (IBCG) guidance and provide practical recommendations on IR NMIBC management. EVIDENCE ACQUISITION A collaborative review of published randomized clinical trials, meta-analyses, systematic reviews, and clinical practice guidance on IR NMIBC published before January 2022 was undertaken using PubMed/Medline. EVIDENCE SYNTHESIS Variation exists between guidelines in defining IR NMIBC. The IBCG recommends defining IR NMIBC as any TaLG tumor that is either recurrent or multifocal or has size ≥3 cm, OR any T1LG tumor. If the 3 tier grading system is used, than any TaG2 tumor would also be considered IR diease regardless of whether new diagnosis or recurrent. Accurate grading and staging of tumor, particularly in ruling out HG/G3 disease and/or carcinoma in situ, are crucial. The IBCG recommends that management of IR NMIBC should be further based on the following risk factors: multifocal tumor (more than one), early recurrence (<1 yr), frequent recurrence (>1/yr), tumor size (≥3 cm), and failure of prior intravesical treatment. Patients with no risk factors are best managed by one dose of postoperative intravesical chemotherapy. Patients with one to two risk factors should be offered additional adjuvant induction intravesical chemotherapy (or bacillus Calmette-Guérin (BCG) if prior chemotherapy has been used). Patients with three or more risk factors should be offered induction plus 1-yr maintenance BCG. Where BCG is not available or recurrent disease following BCG is present, alternative intravesical treatments such as chemotherapy (single agent, combination, or chemohyperthermia) or a clinical trial are recommended. CONCLUSIONS Standardizing the definition of IR NMIBC is critical for appropriate management of patients and for allowing a comparison of outcomes across clinical trials. The IBCG recommends defining IR NMIBC as any TaLG tumor that is either recurrent or multifocal or ≥3 cm, OR any T1LG tumor. If the 3 tier grading system is used, than any TaG2 tumor would also be considered IR disease regardless of whether new diagnosis or recurrent. Adjunctive management should then be based on established risk factors. PATIENT SUMMARY Standardizing the definition of intermediate-risk (IR) non-muscle-invasive bladder cancer (NMIBC), which is a heterogeneous disease, is critical for appropriate management of patients. The International Bladder Cancer Group recommends classification of IR NMIBC tumors and personalized management based on the following risk factors: multifocal tumor (more than one), early recurrence (<1 yr), frequent recurrence (>1/yr), tumor size (≥3 cm), and previous intravesical treatment.

Abstract
PURPOSE Understanding treatment patterns and effectiveness for patients with metastatic prostate cancer (mPCa) is dependent on accurate assessment of metastatic status. The objective was to develop a natural language processing (NLP) model for identifying patients with mPCa and evaluate the model's performance against chart-reviewed data and an International Classification of Diseases (ICD) 9/10 code-based method. METHODS In total, 139,057 radiology reports on 6,211 unique patients from the Department of Veterans Affairs were used. The gold standard was metastases by detailed chart review of radiology reports. NLP performance was assessed by sensitivity, specificity, positive predictive value, negative predictive value, and date of metastases detection. Receiver operating characteristic curves was used to assess model performance. RESULTS When compared with chart review, the NLP model had high sensitivity and specificity (85% and 96%, respectively). The NLP model was able to predict patient-level metastasis status with a sensitivity of 91% and specificity of 81%, whereas sensitivity and specificity using ICD9/10 billing codes were 73% and 86%, respectively. For the NLP model, date of metastases detection was exactly concordant and within < 1 week in 55% and 58% of patients, compared with 8% and 17%, respectively, using the ICD9/10 billing codes method. The area under the curve for the NLP model was 0.911. A limitation is the NLP model was developed on the basis of a subset of patients with mPCa and may not be generalizable to all patients with mPCa. CONCLUSION This population-level NLP model for identifying patients with mPCa was more accurate than using ICD9/10 billing codes when compared with chart-reviewed data. Upon further validation, this model may allow for efficient population-level identification of patients with mPCa.

Abstract
BACKGROUND We sought to determine whether differences in subtype distribution and differentially expressed genes exist between African Americans (AAs) and European Americans (EAs) in patients with high-risk nonmuscle-invasive bladder cancer (NMIBC). METHODS We performed a retrospective cohort study including 26 patients (14 AAs and 12 EAs) from the University of Texas Medical Branch and the Durham Veterans Affair Health Care System from 2010 to 2020 among treatment naïve, high-risk NMIBC. Profiled gene expressions were performed using the UROMOL classification system. RESULTS UROMOL racial subtype distributions were similar with class 2a being most common with 10 genes commonly upregulated in AAs compared to EAs including EFEMP1, S100A16, and MCL1 which are associated with progression to muscle-invasive bladder cancer, mitomycin C resistance, and bacillus Calmette-Guérin durability, respectively. We used single nuclei analysis to map the malignant cell heterogeneity in urothelial cancer which 5 distinct malignant epithelial subtypes whose presence has been associated with different therapeutic response prediction abilities. We mapped the expression of the 10 genes commonly upregulated by race as a function of the 5 malignant subtypes. This showed borderline (P = 0.056) difference among the subtypes suggesting AAs and EAs may be expected to have different therapeutic responses to treatments for bladder cancer. AAs were enriched with immune-related, inflammatory, and cellular regulation pathways compared to EAs, yet appeared to have reduced levels of the aggressive C3/CDH12 bladder tumor cell population. CONCLUSIONS While premature, gene expression differed between AAs and EAs, supporting potential race-based etiologies for muscle-invasion, response to treatments, and transcriptome pathway regulations.

Abstract
PURPOSE To systematically review the literature to investigate racial disparities among bladder cancer clinical trial enrollees. METHODS A systematic review was conducted using Ovid, MEDLINE® to identify clinical trials between 1970 and 2020. Articles were reviewed and were included if they assessed race in their outcomes reporting among bladder cancer patients enrolled in clinical trials. The review was conducted in accordance with the PRISMA statement. RESULTS We identified 544 clinical trials meeting our initial search criteria, with only 24 (4.4%) studies reporting racial demographic data. Enrollees were largely Caucasian (81-98%), with a strikingly small proportion of enrolled patients consisting of African-Americans (2-8%) and Hispanics (2-5%). Only one of the studies reported results on the efficacy and safety/tolerability of the tested treatment separately for racial groups and performed analyses stratified by race. CONCLUSION Race is poorly studied in bladder cancer clinical trials. Trial cohorts may not reflect multicultural populations. The potential association between race and efficacy, safety or tolerability of the tested interventions is unknown. Given the up to twofold increase in bladder cancer-specific death among African-Americans, further research is needed to address the impact of race in clinical trials, while encompassing socioeconomic factors and disease risk factor exposures.

Abstract
Importance Low testosterone levels in males have been linked with increase in proinflammatory cytokines—a primary culprit in COVID‐19 disease progression—and with adverse COVID‐19 outcomes. To date, however, no published studies have assessed the effect of testosterone therapy on COVID‐19 outcomes in older men. Objective To examine whether testosterone therapy reduced disease progression in older men diagnosed with COVID‐19. Design, setting, and participants Nested within a national cohort of older (aged ≥50 years) male patients diagnosed with COVID‐19 between January 1, 2020 and July 1, 2021 from the Optum electronic health record COVID‐19 database, two matched case–control studies of COVID‐19 outcomes were conducted. Cases—defined, respectively, as persons who (a) were hospitalized ≤30 days after COVID‐19 diagnosis (n = 33,380), and (b) were admitted to the intensive care unit or received mechanical ventilation during their COVID‐19 hospitalization (n = 10,273)—were matched 1:1 with controls based on demographic and clinical factors. Exposures Testosterone therapy was defined based on receipt of prescription at ≤60, ≤90, or ≤120 days before COVID‐19 diagnosis. Main outcomes and measures Adjusted odds ratios (ORs) for the risk of hospitalization within 30 days of COVID‐19 diagnosis and intensive care unit admission/mechanical ventilation during COVID‐19 hospitalization. Results The use of testosterone therapy was not associated with decreased odds of hospitalization (≤60 days: OR = 0.92, 95% confidence interval [CI] = 0.70–1.20; ≤90 days: OR = 0.87, 95% CI = 0.68–1.13; ≤120 days: OR = 0.97, 95% CI = 0.72–1.32) or intensive care unit admission/mechanical ventilation (≤60 days: OR = 0.67, 95% CI = 0.37–1.23; ≤90 days: OR = 0.63, 95% CI = 0.36–0.11; ≤120 days: OR = 0.58, 95% CI = 0.29–1.19). Conclusions and relevance This study showed that testosterone therapy was not associated with decreased risks of COVID‐19 adverse outcomes. These findings may provide clinically relevant information regarding testosterone treatment in older men with COVID‐19 and other respiratory viral infections with similar pathogenesis.

Abstract
IMPORTANCE Low-risk non-muscle-invasive bladder cancer (NMIBC) is associated with extremely low rates of progression and cancer-specific mortality; however, patients with low-risk NMIBC may often receive non-guideline-recommended and potentially costly surveillance testing and treatment. OBJECTIVE To describe current surveillance and treatment practices, cancer outcomes, and costs of care for low-grade papillary stage Ta (low-grade Ta) NMIBC and identify factors associated with increased cost of care. DESIGN, SETTING, AND PARTICIPANTS This population-based cohort study identified 13 054 older adults (aged 66-90 years) diagnosed with low-grade Ta tumors in the Surveillance, Epidemiology and End Results-linked Medicare database from January 1, 2004, through December 31, 2013. Medicare claims data through December 31, 2014, were also reviewed. Data were analyzed from April 1 to October 6, 2021. EXPOSURES Surveillance testing and treatment among patients with low-grade Ta NMIBC. MAIN OUTCOMES AND MEASURES The primary outcome was patterns in population-level surveillance and treatment practice over time among patients with low-grade Ta NMIBC. Secondary outcomes were recurrence (defined as receipt of subsequent transurethral resection of bladder tumor >3 months after index diagnosis of NMIBC and initial transurethral resection of bladder tumor), progression (defined as receipt of definitive treatment for bladder cancer), and costs of care. RESULTS Among 13 054 patients who met inclusion criteria, 9596 (73.5%) were male and 3458 (26.5%) were female, with a median age of 76 years (IQR, 71-81 years). A total of 403 patients (3.1%) were Black, 120 (0.9%) were Hispanic, 12 123 (92.9%) were White, and 408 (3.1%) were of other races and/or ethnicities. Rates of surveillance cystoscopy increased over the study period (from 79.3% in 2004 to 81.5% in 2013; P = .007), with patients receiving a median of 3.0 cystoscopies per year (IQR, 2.0-4.0 per year). Rates of upper tract imaging (particularly computed tomography or magnetic resonance imaging) also increased over the study period (from 30.4% in 2004 to 47.0% in 2013; P < .001), with most patients receiving a median of 2.0 imaging tests per year (IQR, 1.0-2.0 per year). The use of urine cytologic testing or other urine biomarker assessment also increased (from 44.8% in 2004 to 54.9% in 2013; P < .001). Rates of adherence to current guidelines were similar over time (eg, a median of 4398 patients [55.2%] received ≤2 cystoscopies per year in 2004-2008 vs a median of 2736 patients [53.8%] in 2009-2013; P = .11), suggesting overuse of all surveillance testing modalities. With regard to treatment, 2250 patients (17.2%) received intravesical bacillus Calmette-Guérin, and 792 patients (6.1%) received intravesical chemotherapy (excluding receipt of a single perioperative dose). Among all patients with low-grade Ta NMIBC, 217 (1.7%) experienced disease recurrence and 52 (0.4%) experienced disease progression. The total annual median costs of low-grade Ta surveillance testing and treatment increased by 60% (from $34 792 in 2004 to $53 986 in 2013), with higher 1-year median expenditures noted among those with disease recurrence ($76 669) vs no disease recurrence ($53 909) at the end of the study period. CONCLUSIONS AND RELEVANCE In this cohort study, despite low rates of disease recurrence and progression, rates of surveillance testing increased during the study period. The annual cost of care also increased over time, particularly among patients with recurrent disease. Efforts to improve adherence to current practice guidelines, with the focus on limiting overuse of surveillance testing and treatment, may mitigate associated increasing costs of care.

Abstract
455 Background: Earlier studies on the cost of muscle-invasive bladder cancer treatments are limited to short-term periods of cost. Our study objective is to compare the 2- and 5-year costs associated with trimodal therapy (TMT) versus radical cystectomy (RC) benchmarked against costs for patients who received no curative treatment. Methods: This cohort study used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database. Medicare expenditures were summed from inpatient, outpatient, and physician services within 2 and 5 years of diagnosis to determine total costs Total Medicare costs at 2-and 5-years following TMT versus RC were compared using inverse probability of treatment-weighted (IPTW) propensity score models. Results: A total of 2,537 patients aged 66-85 years diagnosed with clinical stage T2-4a muscle-invasive bladder cancer from January 1, 2002 through December 31, 2009. Total median costs for patients that received no definitive/systemic treatments (RC, TMT, radiotherapy alone, or chemotherapy alone) were $73,780 vs. $88,275 at 2-and 5-years respectively. Total median costs were significantly higher for TMT than RC at 2-years ($372,839 vs. $191,363, p<0.001) and 5-years ($424,570 vs. $253,651, p<0.001), respectively. TMT had higher outpatient median costs than RC (2-yr: $318,221 vs. $100,900; 5-yr: $367,092 vs. $146,561) with significantly higher costs largely associated with radiology, medications, pathology/laboratory, and other professional services. Conclusions: TMT vs. RC was associated with higher long-term costs among patients with muscle-invasive bladder cancer largely driven by outpatient expenditures. Reduction in costs associated with radiology, medications, pathology/laboratory, and other professional services may improve the value of TMT.[Table: see text]

Abstract
447 Background: Mortality from bladder cancer (BC) increases exponentially once it invades the muscle. At the population level, accurate delineation of these patients is challenging. Methods: To develop and validate a natural language processing (NLP) model for automatically identifying muscle-invasive BC (MIBC) patients, aiding in population-based BC research. All patients with a CPT code for transurethral resection of bladder tumor (TURBT) (N = 76,060) were selected from the Department of Veterans Affairs (VA) Corporate Data Warehouse database. A sample of 600 patients (with 2,337 full-text notes) who had TURBT and confirmed pathology results were selected for NLP model development (500 patients) and validation (100 patients). Muscle-invasion (yes/no), unknown, or no cancer, were confirmed by detailed chart review of pathology notes. The NLP performance was assessed by calculating the sensitivity, positive predictive value (PPV), and overall accuracy at the individual note and patient levels. Results: In the validation cohort, the NLP model had overall accuracy of 88% and 92% at the note and patient levels. Specifically, PPV and specificity for predicting muscle-invasion on note level were 83% and 70%, respectively. The model classified non-muscle invasive BC (NMIBC) with 98% sensitivity at both the note and patient levels. Although the sensitivity for MIBC was 70% for note-level determination, the sensitivity was 86% when evaluated at the patient level. When applying the model to 71,200 patients VA-wide, the model classified 13,642 (19%) as having MIBC and 47,595 (66%) as NMIBC. The NLP model was able to identify invasion status for 96% TURBT patients at the population level. Inherent limitations include relatively small training set given the size of the VA population. Conclusions: This NLP model for identifying muscle-invasion at the population level had high accuracy. The NLP model may be a practical and accurate tool for efficiently identifying BC invasion status and may potentially aid in population-based BC research in the VA.

Abstract
527 Background: Patients with high-risk non-muscle-invasive bladder cancer (NMIBC) have heterogeneous outcomes with African Americans (AAs) having worse survival than European Americans (EAs). It is unknown whether race-based biological differences contribute to this disparity. Methods: We performed a retrospective cohort study including patients from the University of Texas Medical Branch (UTMB) and the Durham VA Health Care System (DVAHCS) from 2010-2020 among treatment naïve, high-risk NMIBC. Profiled gene expressions of high-risk NMIBC by race were performed using the UROMOL classification system. Results: A total of 26 patients (14 AAs and 12 EAs) matched on age and sex were included with no significant difference in clinical stage group (CIS +/- T1 or TaHG vs. TaHG or T1, no CIS), smoking status, or progression. We found a similar racial UROMOL subtype distribution with class 2a being most common. A total of 10 genes were discovered to be commonly upregulated differentially expressed genes (up-DEGs) in AAs vs EAs. EFEMP1, which has been associated with progression to muscle-invasive bladder cancer (MIBC) in vitro, and S100A16 gene expression, which has been implicated with mitomycin C resistance in bladder cancer in vitro, was significantly more common among AAs. We used single nuclei analysis to map the malignant cell heterogeneity in urothelial cancer which five distinct malignant epithelial subtypes whose presence has been associated with different therapeutic response prediction ability. We mapped the expression of the 10 genes commonly up-DEGs by race as a function of the five malignant subtypes. This showed borderline (p = 0.056) differences among the subtypes suggesting AA and EA patients may be expected to have different therapeutic responses to treatments for BC. AAs were enriched with immune-related, inflammatory, and cellular regulation pathways compared to EAs, yet appeared to have reduced levels of the aggressive C3 bladder tumor cell population. Conclusions: In this small sample, we found similar subtype distribution among high-risk NMIBC patients according to race. However, gene expression differs by race, supporting potential novel race-based etiologies for differences in muscle-invasion, response to treatments, and transcriptome pathway regulations. Further biological studies in NMIBC molecular sub-stratification, associated treatment(s), and prognoses in a larger cohort are needed to support these hypotheses.

Abstract
464 Background: Low-risk non-muscle invasive bladder cancer (NMIBC) is associated with extremely low rates of progression and cancer-specific mortality, however, these patients may often receive non-guideline recommended and potentially costly surveillance and treatment(s). We sought to describe current surveillance and treatment practices, oncologic outcomes, and cost of care for low-grade papillary (LG Ta) NMIBC and identify predictors of increased cost of care. Methods: This population-based cohort study identified 13,054 patients diagnosed with LG Ta tumors in the Surveillance, Epidemiology and End Results-Medicare linked database from January 1, 2004 through December 31, 2013. The primary outcome was to characterize trends in population-level surveillance and treatment practice patterns over time among LG Ta patients. The secondary outcomes were recurrence, progression, and costs of care. Results: Of the 13,054 patients who met inclusion criteria, 9,596 (73.5%) were male and 3,485 (26.5%) were female, with a median age of 76 (Interquartile Range (IQR): 71–81) years. Rates of surveillance cystoscopy increased over the study period (79.3% to 81.5%, p = 0.007) with patients undergoing a median of three cystoscopies per year (IQR: 2–4). Rates of upper tract imaging utilization also increased, namely the use of computed tomography (CT) or magnetic resonance imaging (MRI) (30.4% to 47%, p < 0.001), with most patients undergoing a median of two imaging tests per year. Similarly, the use of urine cytology or other urine biomarkers also increased (44.8% to 54.9%, p < 0.001). Rates of compliance with current guidelines decreased over time suggesting overutilization of all surveillance testing modalities. A total of 17.2% of patients received intravesical bacillus-Calmette Guerin (BCG) and 6.1% received intravesical chemotherapy (excluding single perioperative dose). Among all LG Ta patients, 1.7% and 0.4% experienced disease recurrence and progression, respectively. Total annual median costs of LG Ta surveillance and care increased 1.6-fold from $34,792 to $53,986 over the study period, with increased expenditures noted among those with disease recurrence ($53,909 and $76,669). Conclusions: Despite low rates of disease recurrence or progression, rates of surveillance testing increased during the study period. Annual cost of care increased over time, particularly among patients with recurrent disease. Efforts to improve adherence to current practice guidelines, with the focus on limiting overutilization of surveillance testing and overtreatment, may mitigate associated rising costs of care.

Abstract
PURPOSE Mortality from bladder cancer (BC) increases exponentially once it invades the muscle, with inherent challenges delineating at the population level. We sought to develop and validate a natural language processing (NLP) model for automatically identifying patients with muscle-invasive bladder cancer (MIBC). METHODS All patients with a Current Procedural Terminology code for transurethral resection of bladder tumor (TURBT; n = 76,060) were selected from the Department of Veterans Affairs (VA) database. A sample of 600 patients (with 2,337 full-text notes) who had TURBT and confirmed pathology results were selected for NLP model development and validation. The NLP performance was assessed by calculating the sensitivity, specificity, positive predictive value, negative predictive value, F1 score, and overall accuracy at the individual note and patient levels. RESULTS In the validation cohort, the NLP model had average overall accuracies of 94% and 96% at the note and patient levels. Specifically, the F1 score and overall accuracy for predicting muscle invasion at the patient level were 0.87% and 96%, respectively. The model classified nonmuscle-invasive bladder cancer (NMIBC) with overall accuracies of 90% and 93% at the note and patient levels. When applying the model to 71,200 patients VA-wide, the model classified 13,642 (19%) as having MIBC and 47,595 (66%) as NMIBC and was able to identify invasion status for 96% of patients with TURBT at the population level. Inherent limitations include a relatively small training set, given the size of the VA population. CONCLUSION This NLP model, with high accuracy, may be a practical tool for efficiently identifying BC invasion status and aid in population-based BC research.

Abstract
OBJECTIVES To determine the geographic distribution of muscle-invasive bladder cancer mortality according to race in the United States (US). African Americans (AAs) have up to two times the risk of bladder cancer mortality compared to Caucasians. Bladder cancer mortality increases exponentially once it invades the muscle. Geographic heterogeneity in bladder cancer mortality according to race remains to be determined. DESIGN Analysis of Surveillance, Epidemiology, and End Results (SEER)-Medicare data for 6,044 patients aged 66-85 diagnosed with clinical stage T2-T4 N0M0 bladder cancer from 1 January 2002 to 31 December 2011. Fine and Gray-competing risks regression models were used to assess the association of race with bladder cancer-specific mortality (BCSM) according to tumor registry. RESULTS Out of 6,044 patients, 5,408 (89.5%) were Caucasian, 352 (5.82%) were non-Hispanic AA, 85 (1.4%) were Hispanic, and 199 (3.29%) were other. Of the 18 registries, AAs with bladder cancer were largely concentrated in Louisiana (19%), New Jersey (17.9%), and Georgia (17.6%). New Jersey was the only registry where AAs had increased risk of BCSM than Caucasians and only for stage T2 disease: (AHR, 1.74; 95% CI 1.22-2.47, p = 0.002). According to treatment, AAs in New Jersey had worse BCSM than Caucasians when they underwent radical cystectomy (AHR, 2.05; 95% CI 1.26-3.35, p = 0.0039) and radiotherapy or chemotherapy alone (AHR, 1.55; 95% CI 1.03-2.35, p = 0.0367). CONCLUSIONS We observed geographic variation in bladder cancer mortality which impacted only one registry with one of the largest population of AAs. These findings support further investigation into the social determinants of race (i.e., socioeconomic status and distance to healthcare facility) and culturally centered healthcare decision making which may drive these results.

Abstract
Background Upper tract urothelial carcinoma (UTUC) is a heterogeneous disease that presents a clinical management challenge for the urologic surgeon. We assessed treatment patterns, costs, and survival outcomes among patients with nonmetastatic UTUC. Methods We identified 4114 patients diagnosed with nonmetastatic UTUC from 2004 to 2013 in the Survival Epidemiology, and End Results-Medicare population-based database. Patients were stratified into low- or high-risk disease groups. Median total costs from 30 days prior to diagnosis through 365 days after diagnosis were compared between groups. Overall and cancer-specific survival were evaluated using Cox proportional hazards regression. All statistical tests were 2-sided. Results After risk stratification, 1027 (24.9%) and 3087 (75.0%) patients were classified into low- vs high-risk UTUC groups. Most patients underwent at least 1 surgical intervention (95.1%); 68.4% underwent at least 1 endoscopic intervention. Patients diagnosed with high- vs low-risk UTUC were more likely to undergo nephroureterectomy (83.6% vs 72.0%; P < .001); few patients with low-risk disease were exclusively managed endoscopically (16.9%). At 365 days after diagnosis, costs of care for high- vs low-risk UTUC were statistically significantly higher ($108 520 vs $91 233; median difference $16 704, 95% confidence interval [CI] = $11 619 to $21 778; P < .001). Those with high-risk UTUC had worse cancer-specific and overall survival compared with patients with low-risk UTUC (cancer-specific survival hazard ratio [HR] = 4.14, 95% CI = 3.19 to 5.37; overall survival HR = 1.78, 95% CI = 1.62 to 1.96). Conclusions UTUC continues to be managed primarily with nephroureterectomy, regardless of risk stratification, and patients with high-risk UTUC have worse overall and cancer-specific survival. Substantial costs are associated with management of low- and high-risk UTUC, with the latter being more costly up to 1 year from diagnosis.

Abstract
BACKGROUND Multiple single-arm clinical trials showed promising pathologic complete response rates with neoadjuvant immune checkpoint inhibitors (ICIs) in muscle-invasive bladder cancer. We conducted a cost-effectiveness analysis comparing neoadjuvant ICIs with cisplatin-based chemotherapy (CBC). METHODS We applied a decision analytic simulation model with a health care payer perspective to compare neoadjuvant ICIs vs. CBC. For the primary analysis we compared pembrolizumab with ddMVAC. We performed a secondary analysis with gemcitabine/cisplatin as CBC and exploratory analyses with atezolizumab or nivolumab/ipilimumab as ICI. We input pathologic complete response rates from trials or meta-analysis and costs from average sales price. Outcomes of interest included costs, 2-year recurrence-free survival (RFS), and incremental cost-effectiveness ratio (ICER) of cost per 2-year RFS. A threshold analysis estimated a price reduction for ICI to be cost-effective and one-way and probabilistic sensitivity analyses were performed. RESULTS The incremental cost of pembrolizumab compared with ddMVAC was $8,041 resulting in an incremental improvement of 1.5% in 2-year RFS for an ICER of $522,143 per 2-year RFS. A 21% reduction in cost of pembrolizumab would render it more cost-effective with an ICER of $100,000 per 2-year RFS. GC required an 89% pembrolizumab cost reduction to achieve an ICER of $100,000 per 2-year RFS. Atezolizumab appeared to be more cost-effective than ddMVAC. CONCLUSIONS ICIs were not cost-effective as neoadjuvant therapies, except when atezolizumab was compared with ddMVAC. Randomized clinical trials, larger sample sizes and longer follow-up are required to better understand the value of ICIs as neoadjuvant treatments.

Abstract
BACKGROUND The objective of this study was to describe bladder cancer outcomes as a function of race among patients with high-risk non-muscle-invasive bladder cancer (NMIBC) in an equal-access setting. METHODS A total of 412 patients with high-risk NMIBC who received bacille Calmette-Guérin (BCG) from January 1, 2010, to December 31, 2015, were assessed. The authors used the Kaplan-Meier method to estimate event-free survival and Cox regression to determine the association between race and recurrence, progression, disease-specific, and overall survival outcomes. RESULTS A total of 372 patients who had complete data were included in the analysis; 48 (13%) and 324 (87%) were Black and White, respectively. There was no difference in age, sex, smoking status, or Charlson Comorbidity Index by race. White patients had a higher socioeconomic status with a greater percentage of patients living above the poverty level in comparison with Black patients (median, 85% vs 77%; P < .001). A total of 360 patients (97%) received adequate induction BCG, and 145 patients (39%) received adequate maintenance BCG therapy. There was no significant difference in rates of adequate induction or maintenance BCG therapy according to race. There was no significant difference in recurrence (hazard ratio [HR], 1.53; 95% confidence interval [CI], 0.64-3.63), progression (HR, 0.77; 95% CI, 0.33-1.82), bladder cancer-specific survival (HR, 1.01; 95% CI, 0.30-3.46), or overall survival (HR, 0.97; 95% CI, 0.56-1.66) according to Black race versus White race. CONCLUSIONS In this small study from an equal-access setting, there was no difference in the receipt of BCG or any differences in bladder cancer outcomes according to race.

Abstract
OBJECTIVE To determine the estimated budget impact to practices that incorporate blue light cystoscopy (BLC) with hexaminolevulinate HCl (HAL) for the surveillance of non-muscle-invasive bladder cancer (NMIBC) in the clinic setting. With the introduction of advanced technologies in the clinic setting such as HAL, further cost comparative research is needed to justify HAL as a high value option. MATERIAL AND METHODS A budget impact model was developed from the facility perspective assessing projected costs at 2 years for a simulated facility with 50 newly diagnosed bladder cancer patients. Treatment and surveillance cystoscopy intervals were based on clinical guidelines. Clinical inputs, including tumor stage and grade at diagnosis, rates of recurrence and relative risk reduction when using BLC with HAL, were derived from published studies. Cost inputs were based on Medicare reimbursement rates and facility costs. RESULTS Use of BLC identified 9 additional recurrences over two years compared to white light cystoscopy alone. Use of flexible BLC for surveillance marginally increased costs to the practice, with a net difference of $0.76 per cystoscopy over 2 years. CONCLUSIONS From the office/clinic perspective, the model suggests that the use of flexible BLC for the surveillance of NMIBC may not impact cost per cystoscopy and identifies 9 recurrences over 2 years that would be missed using white light cystoscopy alone. These findings could have important implications in the management of NIMBC and help guide clinical practice guidelines that promote cost-effective care and improved patient outcomes.

Abstract
OBJECTIVE Older patients diagnosed with cancer are at increased risk of physical and emotional distress; however, prescription utilization patterns largely remain to be elucidated. Our objective was to comprehensively assess prescription patterns and predictors in older patients with bladder cancer. METHODS A total of 10,516 older patients diagnosed with clinical stage T1-T4a, N0, M0 bladder urothelial carcinoma from 1 January 2008 to 31 December 2012 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare were analyzed. We used multivariable analysis to determine predictors associated with psychotropic prescription rates (one or more). Medication possession ratio (MPR) was used as an index to measure adherence in intervals of 3 months, 6 months, 1 year, and 2 years. Evaluation of psychotropic prescribing patterns and adherence across different drugs and demographic factors was done. RESULTS Of the 10,516 older patients, 5621 (53%) were prescribed psychotropic drugs following cancer diagnosis. Overall, 3972 (38%) patients had previous psychotropic prescriptions prior to cancer diagnosis, and these patients were much more likely to receive a post-cancer diagnosis prescription. Prescription rates for psychotropic medications were higher among patients with higher stage BC (p < 0.001). Gamma aminobutyric acid modulators/stimulators and serotonin reuptake inhibitors/stimulators were the highest prescribed psychotropic drugs in 21% of all patients. Adherence for all drugs was 32% at 3 months and continued to decrease over time. CONCLUSION Over half of the patients received psychotropic prescriptions within 2 years of their cancer diagnosis. Given the chronicity of psychiatric disorders with observed significantly low adherence to medications that warrants an emphasis on prolonged patient monitoring and further investigation.

Abstract
TPS4586 Background: The standard of care for patients with muscle-invasive bladder cancer (MIBC) consists of neoadjuvant chemotherapy and radical cystectomy (RC) or chemoradiotherapy (CRT). However, RC is associated with potential morbidity or mortality from the procedure. TAR-200 is an intravesical drug-delivery system designed for the local continuous release of gemcitabine within the bladder. Cetrelimab is an investigational immunoglobulin G4 anti–programmed cell death protein-1 antibody. In patients with MIBC, this clinical trial will evaluate whether combination treatment with intravesical TAR-200 and systemic cetrelimab will result in enhanced local and systemic antitumor activity versus concurrent CRT. Methods: SunRISe-2 (NCT04658862) is a prospective, multicenter, open-label, randomized phase 3 study evaluating the efficacy and safety of intravesical TAR-200 plus systemic cetrelimab versus CRT in participants with MIBC. Eligible participants are aged ³18 years with an ECOG performance status of 0, 1, or 2, and histologically proven, cT2-T4a, N0, M0 urothelial carcinoma of the bladder diagnosed within 90 days of the randomization date, and who refuse or are ineligible for RC. Approximately 550 participants will be randomized in a 1:1 ratio and with stratification by 2 factors: transurethral resection of bladder tumor screening results (visibly complete vs incomplete) and screening tumor stage (T0 vs Ta/T1/Tis vs T2-T4a). Participants in Arm 1 will receive intravesical TAR-200 every 3 weeks for the first 18 weeks on study; and, beginning at week 24, every 12 weeks through study year 3. Cetrelimab will be dosed every 3 weeks until month 18. Participants in Arm 2 will receive standard of care CRT (with either cisplatin or gemcitabine, for up to 6 weeks). A primary disease assessment will be performed at week 18 to evaluate treatment response in both arms. Subsequent assessments (axial imaging and cystoscopy) will occur at week 24 and every 12 weeks thereafter through study year 2, and then every 24 weeks through study year 5. The primary endpoint is bladder intact event-free survival. Key secondary endpoints include metastasis-free survival, overall survival, overall response rate (at week 18), and safety and tolerability. Other/exploratory end points include assessments of cancer-specific survival, time to symptomatic progression, pharmacokinetics, immunogenicity, health-related quality of life, healthcare resource utilization, and biomarkers. Participants are being enrolled at approximately 272 study sites worldwide. The study opened for enrollment in December 2020. Clinical trial information: NCT04658862.

Abstract
IMPORTANCE Management of high-risk non-muscle-invasive bladder cancer (NMIBC) represents a clinical challenge due to high failure rates despite prior bacillus Calmette-Guérin (BCG) therapy. OBJECTIVE To describe real-world patient characteristics, long-term outcomes, and the economic burden in a population with high-risk NMIBC treated with BCG therapy. DESIGN, SETTING, AND PARTICIPANTS This retrospective cohort study identified 412 patients with high-risk NMIBC from 63 139 patients diagnosed with bladder cancer who received at least 1 dose of BCG within Department of Veterans Affairs (VA) centers across the US from January 1, 2000, to December 31, 2015. Adequate induction BCG therapy was defined as at least 5 installations, and adequate maintenance BCG therapy was defined as at least 7 installations. Data were analyzed from January 2, 2020, to January 20, 2021. EXPOSURES Intravesical BCG therapy, including adequate induction BCG therapy, was defined as at least 5 intravesical instillations of BCG within 70 days from BCG therapy start date. Adequate maintenance BCG therapy was defined as at least 7 installations of BCG within 274 days of the start (the first instillation) of adequate induction BCG therapy (ie, adequate induction BCG plus some form of additional BCG). MAIN OUTCOMES AND MEASURES The Kaplan-Meier method was used to estimate outcomes, including event-free survival. All-cause expenditures were summarized as medians with corresponding interquartile ranges (IQRs) and adjusted to 2019 USD. RESULTS Of the 412 patients who met inclusion criteria, 335 (81%) were male and 77 (19%) were female, with a median age of 67 (IQR, 61-74) years. Follow-up was 2694 person-years. A total of 392 patients (95%) received adequate induction BCG therapy, and 152 (37%) received adequate BCG therapy. For all patients with high-risk NMIBC, the 10-year progression-free survival rate and disease-specific death rate were 78% and 92%, respectively. Patients with carcinoma in situ (Cis) had worse disease-free survival than those without Cis (hazard ratio [HR], 1.85; 95% CI, 1.34-2.56). Total median costs at 1 year were $29 459 (IQR, $14 991-$52 060); at 2 years, $55 267 (IQR, $28 667-$99 846); and at 5 years, $117 361 (IQR, $59 680-$211 298). Patients with progressive disease had significantly higher median 5-year costs ($232 729 [IQR, $151 321-$341 195] vs $94 879 [IQR, $52 498-$172 631]; P < .001), with outpatient care, pharmacy, and surgery-related costs contributing. CONCLUSIONS AND RELEVANCE Despite adequate induction BCG therapy, only 37% of patients received adequate BCG therapy. Patients with Cis had increased risk of progression, and progression regardless of Cis was associated with significantly increased costs relative to patients without progression. Extrapolating cost figures, regardless of progression, resulted in nationwide costs at 1 year of $373 million for patients diagnosed with high-risk NMIBC in 2019.

Cost-effectiveness analysis of neoadjuvant immune checkpoint inhibition (ICI) versus cisplatin-based chemotherapy (CBC) in muscle-invasive bladder cancer (MIBC). J Clin Oncol 2021.

Abstract
419 Background: Multiple single-arm clinical trials have shown promising pathologic complete response (pCR) rates with neoadjuvant ICIs in MIBC. However, ICIs remain costly. We conducted a cost-effectiveness analysis comparing neoadjuvant ICIs with CBC. Methods: We applied a decision analytic simulation model with a health care payer perspective and two-year time horizon to compare neoadjuvant ICIs vs CBC. For the primary analysis we compared pembrolizumab with dose dense methotrexate, vinblastine, doxorubicin, and cisplatin (ddMVAC). We performed a secondary analysis with gemcitabine/cisplatin (GC) as CBC and exploratory analyses with atezolizumab or nivolumab/ipilimumab as ICIs (vs both ddMVAC and GC). We input pCR rates from trials (ICIs) or a weighted average of prior studies (CBC) and costs from average sales price. Outcomes of interest included costs, 2-year recurrence-free survival (RFS), and incremental cost-effectiveness ratio (ICER) of cost per 2-year RFS. A threshold analysis estimated a pCR rate or price reduction for ICI to be cost-effective and one-way and probabilistic sensitivity analyses were performed. Results: Results of the cost effectiveness analysis are shown in the table. The incremental cost of pembrolizumab compared with ddMVAC was $8,042 resulting in an incremental improvement of 0.66% in 2-year RFS for an ICER of $1,218,485 per 2-year RFS. A pCR of 71% or a 26% reduction in cost of pembrolizumab would render it more cost-effective with an ICER of $100,000 per 2-year RFS. GC required a 96% pembrolizumab cost reduction to achieve an ICER of $100,000 per 2-year RFS. Atezolizumab appeared to be more cost-effective than ddMVAC, even though the 2yr RFS was 0.66% worse. Conclusions: ICIs were not cost-effective as neoadjuvant therapies, except when atezolizumab was compared with ddMVAC. Pembrolizumab would approach cost-effective thresholds with 26% or 96% reduction in cost when compared to ddMVAC and GC, respectively. Randomized clinical trials, larger sample sizes and longer follow-up are required to better understand the value of ICIs as neoadjuvant treatments. [Table: see text]

Abstract
Supplemental Digital Content is available in the text. The General Data Protection Regulation (GDPR) became binding law in the European Union Member States in 2018, as a step toward harmonizing personal data protection legislation in the European Union. The Regulation governs almost all types of personal data processing, hence, also, those pertaining to biomedical research. The purpose of this article is to highlight the main practical issues related to data and biological sample sharing that biomedical researchers face regularly, and to specify how these are addressed in the context of GDPR, after consulting with ethics/legal experts. We identify areas in which clarifications of the GDPR are needed, particularly those related to consent requirements by study participants. Amendments should target the following: (1) restricting exceptions based on national laws and increasing harmonization, (2) confirming the concept of broad consent, and (3) defining a roadmap for secondary use of data. These changes will be achieved by acknowledged learned societies in the field taking the lead in preparing a document giving guidance for the optimal interpretation of the GDPR, which will be finalized following a period of commenting by a broad multistakeholder audience. In parallel, promoting engagement and education of the public in the relevant issues (such as different consent types or residual risk for re-identification), on both local/national and international levels, is considered critical for advancement. We hope that this article will open this broad discussion involving all major stakeholders, toward optimizing the GDPR and allowing a harmonized transnational research approach.
