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
INTRODUCTION It is unknown whether race/ethnicity affects access and/or survival after neoadjuvant (NAC) or adjuvant chemotherapy (ADJ) at radical cystectomy (RC). We addressed these knowledge gaps. MATERIAL AND METHODS Within the Surveillance, Epidemiology, and End Results database (2007-2020), we identified NAC candidates (T2-T4N0M0) and ADJ candidates (T3-T4 and/or N1-3). We focused on the four most prevalent race/ethnicities: Caucasians, Hispanics, African American (AA), and Asian/Pacific Islanders (API). Multivariable logistic regression models (MLR) tested access to NAC and ADJ. Subsequently, within NAC-exposed patients, survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression models addressed CSM according to race/ethnicity were fitted. We repeated the same methodology in ADJ-exposed patients. RESULTS In 6418 NAC candidates, NAC was administered in 1011 (19.0%) Caucasians, 88 (21.0%) Hispanics, 65 (17.0%) AA, and 53 (18.0%) API. In MLR, AA exhibited lower access rates to NAC (OR 0.83, p = 0.04). In NAC-exposed patients, AA independently predicted higher CSM (HR 1.3, p < 0.001) and API independently predicted lower CSM (HR 0.83, p = 0.03). Similarly, in 5195 ADJ candidates, ADJ was administered to 1387 (33.0%) Caucasians, 100 (28.0%) Hispanics, 105 (29.0%) AA, and 90 (37.0%) API. In MLR, AA (OR 68, p = 0.003) and Hispanics (OR 0.69, p = 0.004) exhibited lower access rates to ADJ. In ADJ-exposed patients, AA independently predicted lower CSM (HR 1.32, p < 0.001), while API showed better CSM (HR 0.82, p = 0.01). CONCLUSION Relative to Caucasians, AA are less likely to receive either NAC or ADJ. Moreover, relative to Caucasians, AA exhibit higher CSM even when treated with either NAC or ADJ.

Abstract
Background Multiagent neoadjuvant chemotherapy (NAT) has been linked with improved survival for locally advanced (LA) or borderline resectable (BR) pancreatic ductal adenocarcinoma (PDAC). However, the existence of disparities in its utilization remains to be elucidated. Methods All adults with PDAC were tabulated from the 2011-2017 Nationwide Cancer Database. Tumor vascular involvement was determined using the clinical T stage and CS_EXTENSION variables. The significance of temporal trends was calculated using Cuzick's non-parametric test. A Cox proportional hazard model was used to assess the impact of NAT utilization on hazard of two-year mortality. A logistic regression model was developed to determine factors associated with receipt of NAT. Results Of 3811 patients meeting inclusion criteria, 50.8 % received NAT. NAT utilization significantly increased over the study period, from 31.7 % in 2011 to 81.1 % in 2017 (p < 0.001). NAT was associated with significantly reduced two-year mortality (Hazards Ratio 0.34, 95 % Confidence Interval [CI] 0.18-0.67).After adjustment, younger (Adjusted Odds Ratio [AOR] 0.97/year, CI 0.96-0.98) and Black (AOR 0.65, CI 0.48-0.89; ref: White) patients demonstrated reduced odds of NAT. Furthermore, patients with Medicare (AOR 0.73, CI 0.59-0.90; ref: Private) or Medicaid insurance (AOR 0.67, CI 0.46-0.97; ref: Private) had lower odds of NAT, as did those treated at non-academic institutions (Community: AOR 0.42, CI 0.35-0.52, Integrated: 0.68, CI 0.54-0.85) or in the lowest education quartile (AOR 0.52, CI 0.29-0.95; ref: Highest). Conclusions We identified increasing utilization of NAT for BR/LA pancreatic adenocarcinoma. Despite being linked with significantly reduced two-year mortality, socioeconomic disparities affect odds of NAT.

Development and validation of competing risk nomograms for predicting cancer‑specific mortality in non-metastatic patients with non‑muscle invasive urothelial bladder cancer. Sci Rep 2024; 14:17641. [PMID: 39085366 PMCID: PMC11291689 DOI: 10.1038/s41598-024-68474-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Accepted: 07/24/2024] [Indexed: 08/02/2024] Open
Abstract
We aimed to assess the cumulative incidences of cancer-specific mortality (CSM) in non-metastatic patients with non‑muscle invasive urothelial bladder cancer (NMIUBC) and establish competing risk nomograms to predict CSM. Patient data was sourced from the Surveillance, Epidemiology, and End Results database, as well as the electronic medical record system in our institution to form the external validation cohort. Sub-distribution proportional hazards model was utilized to determine independent risk factors influencing CSM in non-metastatic NMIUBC patients. Competitive risk nomograms were constructed to predict 3-year, 5-year, and 8-year cancer-specific survival (CSS) in all patients group, TURBT group and cystectomy group, respectively. The discrimination and accuracy of the model were validated through the concordance index (C-index), the area under the receiver operating characteristic curve (AUC), and calibration curves. Decision curve analysis (DCA) and a risk stratification system was employed to evaluate the clinical utility of the model. Race, age, marital status, surgery in other sites, tumor size, histological type, histological grade, T stage and N stage were identified as independent risk factors to predict CSS in all patients group. The C-index for 3-year CSS was 0.771, 0.770 and 0.846 in the training, testing and external validation sets, respectively. The ROC curves showed well discrimination and the calibration plots were well fitted and consistent. Moreover, DCA demonstrated well clinical effectiveness. Altogether, the competing risk nomogram displayed excellent discrimination and accuracy for predicting CSS in non-metastatic NMIUBC patients, which can be applied in clinical practice to help tailor treatment plans and make clinical decisions.

Abstract
Racial and ethnic minority populations experience poorer cancer outcomes compared to non-Hispanic White populations, but qualitative studies have typically focused on single subpopulations. We explored experiences, perceptions, and attitudes toward cancer care services across the care continuum from screening through treatment among African American and Hispanic residents of Nebraska to identify unique needs for education, community outreach, and quality improvement. We conducted four focus groups (N = 19), April-August 2021 with people who were aged 30 or older and who self-identified as African American or Hispanic and as cancer survivors or caregivers. Sessions followed a structured facilitation guide, were audio recorded and transcribed, and were analyzed with a directed content analysis approach. Historical, cultural, and socioeconomic factors often led to delayed cancer care, such as general disuse of healthcare until symptoms were severe due to mistrust and cost of missing work. Obstacles to care included financial barriers, transportation, lack of support groups, and language-appropriate services (for Hispanic groups). Knowledge of cancer and cancer prevention varied widely; we identified a need for better community education about cancer within the urban Hispanic community. Participants had positive experiences and a sense of hope from the cancer care team. African American and Hispanic participants shared many similar perspectives about cancer care. Our results are being used in collaboration with national and regional cancer support organizations to expand their reach in communities of color, but structural and cultural barriers still need to be addressed.

The potential role of precision medicine to alleviate racial disparities in prostate, bladder and renal urological cancer care. BJUI COMPASS 2024; 5:405-425.

Abstract
Background Racial disparities in oncological outcomes resulting from differences in social determinants of health (SDOH) and tumour biology are well described in prostate cancer (PCa) but similar inequities exist in bladder (BCa) and renal cancers (RCCs). Precision medicine (PM) aims to provide personalized treatment based on individual patient characteristics and has the potential to reduce these inequities in GU cancers. Objective This article aims to review the current evidence outlining racial disparities in GU cancers and explore studies demonstrating improved oncological outcomes when PM is applied to racially diverse patient populations. Evidence acquisition Evidence was obtained from Pubmed and Web of Science using keywords prostate, bladder and renal cancer, racial disparity and precision medicine. Because limited studies were found, preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines were not applied but rather related articles were studied to explore existing debates, identify the current status and speculate on future applications. Results Evidence suggests addressing SDOH for PCa can reverse racial inequities in oncological outcomes but differences in incidence remain. Similar disparities in BCa and RCC are seen, and it would be reasonable to suggest achieving parity in SDOH for all races would do the same. Research applying a PM approach to different ethnicities is lacking although in African Americans (AAs) with metastatic castrate-resistant prostate cancer (mCRPCa) better outcomes have been shown with androgen receptor inhibitors, radium-223 and sipuleucel. Exploiting the abscopal effect with targeted radiation therapy (RT) and immunotherapy has promise but requires further study, as does defining actionable mutations in specific patient groups to tailor treatments as appropriate. Conclusion For all GU cancers, the historical underrepresentation of ethnic minorities in clinical trials still exists and there is an urgent need for recruitment strategies to address this. PM is a promising development with the potential to reduce inequities in GU cancers, however, both improved understanding of race-specific tumour biology, and enhanced recruitment of minority populations into clinical trials are required. Without this, the benefits of PM will be limited.

Abstract
INTRODUCTION Trimodal therapy (TMT) is the most validated bladder-sparing treatment for organ-confined urothelial carcinoma of the urinary bladder (OC UCUB, namely cT2N0M0). However, it is unknown if barriers to the use of TMT or cancer-specific mortality (CSM) differences exist according to race/ethnicity. We addressed this knowledge gap. MATERIAL AND METHODS Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified OC UCUB patients aged from 18 to 85 treated with radical cystectomy (RC) or TMT. Temporal trends described TMT versus RC use over time. Subsequently, in the subgroup of TMT-treated patients, survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression (MCR) models addressed CSM according to race/ethnicity. RESULTS Among 19,501 assessable patients, 15,336 (79%) underwent RC versus 4165 TMT (21%). Overall, of all races/ethnicities, 16,245 (83.3%) were White Americans, 1215 (6.3%) Hispanics, 1160 (5.9%) African Americans, and 881 (4.5%) Asian/Pacific Islanders. Among TMT-treated patients, 3460 (83.1%) were White Americans, 298 (7.1%) African Americans, 218 (5.3%) Hispanics, and 189 (4.5%) Asian/Pacific Islanders. The lowest rate of TMT use relative to RC and TMT patients was recorded in Hispanics (17.9%). Over time, TMT use increased in White Americans (EAPC: + 4.5%, p = 0.001) and Asians/Pacific Islanders (EAPC: + 5.2%, p = 0.003), but not in others. Kaplan-Meier analyses showed median CSM of 49 months, 41 months, and 34 months and not reached in White Americans, Hispanics, African Americans, and Asian/Pacific Islanders, respectively (p = 0.02). In MCR models, two race/ethnicity subgroups independently predicted either worse (African Americans, HR: 1.20, p = 0.02) or better CSM (Asian/Pacific Islanders, HR: 0.75, p = 0.02). CONCLUSION Race/ethnicity affects both access to TMT (lower access in Hispanics) as well as survival after TMT (better in Asians/Pacific Islanders and worse in African Americans).

Establishment and validation of nomograms to predict the overall survival and cancer-specific survival for non-metastatic bladder cancer patients: A large population-based cohort study and external validation. Medicine (Baltimore) 2024; 103:e37492. [PMID: 38489693 PMCID: PMC10939645 DOI: 10.1097/md.0000000000037492] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/14/2023] [Revised: 01/08/2024] [Accepted: 02/14/2024] [Indexed: 03/17/2024] Open
Abstract
This study aimed to develop nomograms to accurately predict the overall survival (OS) and cancer-specific survival (CSS) of non-metastatic bladder cancer (BC) patients. Clinicopathological information of 260,412 non-metastatic BC patients was downloaded from the Surveillance, Epidemiology, and End Results (SEER) database from 2000 to 2020. LASSO method and Cox proportional hazard regression analysis were utilized to discover the independent risk factors, which were used to develop nomograms. The accuracy and discrimination of models were tested by the consistency index (C-index), the area under the subject operating characteristic curve (AUC) and the calibration curve. Decision curve analysis (DCA) was used to test the clinical value of nomograms compared with the TNM staging system. Nomograms predicting OS and CSS were constructed after identifying independent prognostic factors. The C-index of the training, internal validation and external validation cohort for OS was 0.722 (95%CI: 0.720-0.724), 0.723 (95%CI: 0.721-0.725) and 0.744 (95%CI: 0.677-0.811). The C-index of the training, internal validation and external validation cohort for CSS was 0.794 (95%CI: 0.792-0.796), 0.793 (95%CI: 0.789-0.797) and 0.879 (95%CI: 0.814-0.944). The AUC and the calibration curves showed good accuracy and discriminability. The DCA showed favorable clinical potential value of nomograms. Kaplan-Meier curve and log-rank test uncovered statistically significance survival difference between high- and low-risk groups. We developed nomograms to predict OS and CSS for non-metastatic BC patients. The models have been internally and externally validated with accuracy and discrimination and can assist clinicians to make better clinical decisions.

Abstract
Neoadjuvant cisplatin-based chemotherapy (NACC) followed by radical cystectomy is the standard treatment for localized muscle-invasive bladder cancer (MIBC). Patients who achieve a complete pathological response following NACC have better overall survival than those with residual disease. However, a subset of patients does not derive benefit from NACC while experiencing chemotherapy-related side effects that may delay cystectomy, which can be detrimental. There is a need for predictive and prognostic biomarkers to better stratify patients who will derive benefits from NACC. This review summarizes the currently available literature on various predictors of response to neoadjuvant chemotherapy. Covered predictors include clinical factors, treatment regimens (including chemotherapy and immunotherapy), histological predictors, and molecular predictors such as DNA repair genes, p53, FGFR3, ERBB2, Bcl-2, EMMPRIN, survivin, choline-phosphate cytidylyltransferase-α, epigenetic markers, immunological markers, other molecular predictors and gene expression profiling. Further, we elaborate on the potential role of neoadjuvant immunotherapy and the correlative biomarkers of response.

Urol Oncol 2023; 41:431.e7-431.e14. [PMID: 37295979 DOI: 10.1016/j.urolonc.2023.05.019] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 04/26/2023] [Accepted: 05/21/2023] [Indexed: 06/12/2023]
Abstract
OBJECTIVE Among patients diagnosed with non-muscle invasive bladder cancer (NMIBC), those with high risk disease have the greatest risk of recurrence and disease progression. The underutilization of intravesical immunotherapy with Bacillus Calmette-Guérin (BCG) has been a longstanding concern in clinical practice. This study aimed to determine the disparities present in receipt of adjuvant intravesical chemotherapy and immunotherapy in treatment of patients with high grade NMIBC following initial transurethral resection of a bladder tumor (TURBT). METHODS The California Cancer Registry data was used to identify 19,237 patients diagnosed with high grade NMIBC who underwent TURBT. Treatment variables include re-TURBT, re-TURBT and intravesical chemotherapy (IVC) and/or BCG. Independent variables include age, sex, race/ethnicity, neighborhood socioeconomic status (nSES), primary insurance payer and marital status at diagnosis. Multiple logistic regression and multinomial regression models were used to examine variation in the treatments received following TURBT. RESULTS The proportion of patients receiving TURBT followed by BCG was similar across all racial and ethnic groups (28%-32%). BCG therapy was higher in patients belonging to the highest nSES quintile (37% for highest vs. 23%-26% for the 2 lowest quintiles). In multiple variable analyses, receipt of any intravesical therapy (IVT) was influenced by nSES, age, marital status, race/ethnicity, and insurance type. Patients in the lowest nSES quintile had a 45% less likelihood of receiving IVT compared to the highest nSES group (OR [95%CI]: 0.55[0.49, 0.61]). Race/ethnicity differences in receipt of any adjuvant therapy were noted in the middle to lowest nSES quintile for Hispanic and Asian/Pacific Islander patients when compared to non-Hispanic White patients. When comparing variation in treatment by insurance type at diagnosis, those with Medicare or other insurance were 24% and 30% less likely to receive BCG after TURBT compared to those with private insurance, (OR [95%CI]: 0.76 [0.70, 0.82] and 0.70[0.62, 0.79]) respectively. CONCLUSION In patients with a diagnosis of high risk NMIBC, disparities in utilization of BCG are seen based on SES, age, and insurance type.

Abstract
BACKGROUND Traditional estimates can only provide static predictions of cancer outcomes and cannot assess the evolving effect of race on patient survival. This study aims to reveal the dynamic survival of patients with bladder cancer and to explore the evolving effect of race on patient prognosis. METHODS Using data from the Surveillance, Epidemiology, and End Results (SEER) registry, 99,590 white, 6,036 African American, and 4,685 Asian/Pacific Islander (API) patients with bladder cancer were identified. Conditional cancer-specific survival (CSS) rates, which could reflect the dynamic survival prediction of cancer patients, represented the primary outcomes, and were estimated by the Kaplan-Meier algorithm. The evolving effect of race on patient survival was evaluated by multivariable Cox regression in combination with conditional survival (CS) estimates. RESULTS The 5-year CSS for African American patients who had survived 1, 2, 3, 4, or 5 years after definitive therapy improved from the baseline calculation by + 5.8 (84.4%), + 9.5 (87.4%), + 12.8 (90.0%), + 14.4 (91.3%), and + 14.7% (91.5%), respectively. The increasing trend also held for overall white and API patients, and for all patient subsets when CS was calculated according to different levels of sex, age, and disease stage. African Americans, despite having the worst survival at baseline, could have CSS comparable to their white and API counterparts after 4 years of survivorship. In addition, the risk of death for African Americans tended to decrease with increasing survival, and the risk was no longer significantly different from that of whites after 4 years of survival. CONCLUSIONS While having the worst initial predicted outcomes, African Americans may eventually achieve comparable survival to white and API patients given several years of survivorship. As patient survival increases, African American race may lose its role as an indicator of poorer prognosis.

Abstract
OBJECTIVE To examine the association of area-level socioeconomic status, rural-urban residence, and type of insurance with overall and cancer-specific mortality among patients with muscle-invasive bladder cancer. METHODS Using the Pennsylvania Cancer Registry, which collects demographic, insurance, and clinical information on every patient with cancer within the state, we identified all patients diagnosed with non-metastatic muscle-invasive bladder cancer between 2010 and 2016 based on clinical and pathologic staging. We used the Area Deprivation Index (ADI) as a surrogate for socioeconomic status and Rural-Urban Commuting Area codes to classify urban, large town, and rural communities. ADI was reported in quartiles, with 4 representing the lowest socioeconomic status. We fit multivariable logistic regression and Cox models to assess the relationship of these social determinants with overall and cancer-specific survival adjusting for age, sex, race, stage, treatment, rural-urban classification, insurance and ADI. RESULTS We identified 2597 patients with non-metastatic muscle-invasive bladder cancer. On multivariable analysis, Medicare (hazards ratio [HR] 1.15), Medicaid (HR 1.38), ADI 3 (HR 1.16) and ADI 4 (HR 1.21) were independent predictors of greater overall mortality (all P < 0.05). Female sex and receipt of non-standard treatment were associated with increased overall mortality and bladder cancer-specific mortality. There was no significant difference in both overall and cancer-specific survival between patients who were non-Hispanic White compared to non-White or between those from urban areas, large towns, or rural locations. CONCLUSION Lower socioeconomic status and Medicare and Medicaid insurance were associated with a greater risk of overall mortality while rural residence was not a significant factor. Implementation of public health programs may help reduce the gap in mortality for low SES at-risk populations.

Abstract
PURPOSE Examine patient, tumor, and treatment characteristics effect on the disparity between black and white patients with muscle-invasive bladder cancer (MIBC) who undergo radical cystectomy (RC). METHODS 1,286 black patients in the 2004 to 2016 National Cancer Database fit inclusion criteria. A tapered match was performed from 17,374 white patients sequentially matched to the black cohort on demographics (age, gender, insurance, income, education, county, diagnosis year), presentation (demographic variables, stage, grade, tumor size, Charlson score), and treatment (demographic and presentation variables, lymph node count, hospital volume, neoadjuvant chemotherapy [NAC], treatment delay), creating 3 matched cohorts. Chi-square and Kruskal-Wallis tests were used to compare cohorts. Kaplan-Meier analysis was used to compare 5-year overall survival (OS). RESULTS 5-year OS rate was 40.4% and 35.6% for unmatched white and black cohorts (P < 0.001), respectively. Following demographics and presentation match, 5-year OS rate for white patients decreased to 39.2% (P = 0.003) and 39.10% (P = 0.019), respectively. After treatment match, 5-year OS rate decreased to 36.7% for white patient (P = 0.32). Following presentation match, 7.2% of black patients vs. 5.8% of white patients had treatment delay, and 10.1% of black patients vs. 11.2% of white patients received NAC. The treatment match resulted in a 0.3% difference between groups for treatment delay and NAC. CONCLUSIONS Our analysis demonstrates that disparity between black and white patients with muscle-invasive bladder cancer exists in demographic-, presentation-, and treatment-related variables. Treatment variables may be a large contributing factor to survival disparities. Further research is needed to identify social, biological, and organizational inputs that contribute to these disparities.

Abstract
Background Radical cystectomy (RC) is considered a complex procedure that entails significant morbidity and mortality. Objectives We aimed to determine pre-operative patient characteristics that help predict a prolonged length of hospital stay (PLOS) following RC. Design and Methods The American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP) database was used to select patients who underwent RC between the years 2011 and 2020. Prolonged length of stay was defined as a hospital stay ⩾9 days. We compared patient demographics, pre-operative labs, surgical characteristics, and medical history between patients with or without PLOS. Multivariable logistic regression models controlling for pre-operative characteristics and propensity score matching for post-operative complications were conducted to control for possible confounders. Results The analysis yielded details of 19,158 RC patients of which 6007 (31%) patients had a PLOS. Patients with PLOS were more likely to have post-operative complications that could serve as predictors for the PLOS rather than their pre-operative characteristics. Hence, we matched our cohort for these complications. After matching, patient pre-operative characteristics that predict PLOS included female gender (Odds Ratio (OR) = 5.91), 10-year increase in age (OR = 1.15), non-White race (OR = 1.98), partially or totally dependent functional health status (OR = 2.86), bleeding disorders (OR = 4.67), congestive heart failure (OR = 1.59), pre-operative transfusion (OR = 3.03), and a 20-min increase in operative time (OR = 1.01) (p < 0.046). Conclusion Patient demographics and pre-operative factors can help predict PLOS in RC patients. These predictors could serve as tools for patient counseling and risk stratification.

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.

Disparities in patient and system factors explain racial/ethnic disparities in delayed time to treatment in muscle invasive bladder cancer. Urol Oncol 2022; 40:343.e15-343.e20. [PMID: 35339357 DOI: 10.1016/j.urolonc.2022.02.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2021] [Revised: 02/07/2022] [Accepted: 02/10/2022] [Indexed: 11/19/2022]
Abstract
PURPOSE Treatment delays in muscle invasive bladder cancer (MIBC) have been shown to be associated with worse outcomes. While every attempt is made to provide adequate treatment expeditiously, Black and Hispanic patients often experience delays at a higher rate than their White counterparts. This study aims to quantify the mechanisms that contribute to this disparity in treatment delay. METHODS Retrospective analysis of clinical T-stages II-IVa MIBC patients who underwent surgical resection from 2004 to 2017 in the National Cancer Database. A causal inference mediation analysis using the counterfactual framework was implemented to estimate the extent to which racial/ethnic disparities in patient and system factors explain the racial/ethnic disparities in time to treatment. Mediators included income, education, comorbidities, insurance, and hospital type. RESULTS Among 22,864 patients who met inclusion criteria, 7%, 3%, 2% were of Black, Hispanic, and Other race/ethnicity, respectively. In multivariable models, compared to White patients, Black, and Hispanic patients were associated with 26% (odds ratio = 1.26, 95% confidence interval = 1.12-1.42) and 29% (odds ratio = 1.29, 95% confidence interval = 1.07-1.55) increased odds of having a treatment delay relative to White patients. Mediation analyses suggested that 49% and 26% the treatment delay among Black and Hispanic patients, respectively, could be removed if an intervention equalized the distribution of academic treatment, education, and insurance status to that of White patients. Treatment at an academic hospital and education were the mediators that explained the largest portion of the racial/ethnic disparity in treatment delay. CONCLUSION Black and Hispanic MIBC patients experience treatment delays when compared to White patients. Intervening upon patient and system factors could reduce substantial treatment delays. Future research is needed to identify other causes of disparities in treatment delays and may help population health initiatives to address racial/ethnic disparities in clinical settings.

Abstract
Bladder Cancer (BLCA) is the ninth most frequently diagnosed cancer globally and the sixth most common cancer in the US. African Americans (AA) exhibit half the BLCA incidence compared to European Americans (EA), but they have a 70% higher risk of cancer-related death; unfortunately, this disparity in BLCA mortality remains poorly understood. In this study, we have used an ethnicity-balanced cohort for unbiased lipidomics profiling to study the changes in the lipid fingerprint for AA and EA BLCA tissues collected from similar geographical regions to determine a signature of ethnic-specific alterations. We identified 86 lipids significantly altered between self-reported AA and EA BLCA patients from Augusta University (AU) cohort. The majority of altered lipids belong to phosphatidylcholines (PCs), phosphatidylethanolamines (PEs), ly sophosphatidylcholines (lysoPCs), phosphatidylserines (PSs), and diglycerides (DGs). Interestingly, levels of four lysoPCs (lyso PCs 20:3, lyso PCs 22:1, lyso PCs 22:2, and lyso PCs 26:1) were elevated while, in contrast, the majority of the PCs were reduced in AA BLCA. Significant alterations in long-chain monounsaturated (MonoUN) and polyunsaturated (PolyUN) lipids were also observed between AA and EA BLCA tumor tissues. These first-in-field results implicate ethnic-specific lipid alterations in BLCA.

Abstract
BACKGROUND To measure the quality of care for lip and oral cavity cancer worldwide using the data from the Global Burden of Disease (GBD) Study 2017. METHODS After devising four main indices of quality of care for lip and oral cavity cancer using GBD 2017 study's measures, including prevalence, incidence, years of life lost, years lived with disability, and disability-adjusted life years, we utilised principal component analysis (PCA) to determine a component that bears the most proportion of info among the others. This component of the PCA was considered as the Quality-of-Care Index (QCI) for lip and oral cavity cancer. The QCI score was then reported in both men and women worldwide and different countries based on the socio-demographic index (SDI) and World Bank classifications. RESULTS Between 1990 and 2017, care quality continuously increased globally (from 53.7 to 59.6). In 1990, QCI was higher for men (53.5 for men compared with 50.8 for women), and in 2017 QCI increased for both men and women, albeit a slightly higher rise for women (57.2 for men compared with 59.9 for women). During the same period, age-standardised QCI for lip and oral cavity cancer increased in all regions (classified by SDI and World Bank). Globally, the highest QCI scores were observed in the elderly age group, whereas the least were in the adult age group. Five countries with the least amount of QCIs were all African. In contrast, North American countries, West European countries and Australia had the highest indices. CONCLUSION The quality of care for lip and oral cavity cancer showed a rise from 1990 to 2017, a promising outcome that supports patient-oriented and preventive treatment policies previously advised in the literature. However, not all countries enjoyed such an increase in the QCI to the same extent. This alarming finding could imply a necessary need for better access to high-quality treatments for lip and oral cavity cancer, especially in central African countries and Afghanistan. More policies with a preventive approach and paying more heed to the early diagnosis, broad insurance coverage, and effective screening programs are recommended worldwide. More focus should also be given to the adulthood age group as they had the least QCI scores globally.

Abstract
BACKGROUND Socioeconomics, demographics, and insurance status play roles in healthcare access. Considering the limited resources available, understanding the relative impact of disparities helps prioritize programs designed to overcome them. This study evaluates gastrointestinal cancer care disparity by comparing the impact of different patient factors across oncologic care metrices. METHODS A multi-institutional prospectively maintained cancer database was reviewed retrospectively for gastrointestinal cancers (esophagus, stomach, liver, pancreas, colorectal, and hepato-pancreato-biliary) from 2007 to 2017 to assess quality of care provided. Quality of care was defined by clinical course following national guidelines for the respective cancer. This included surgical intervention, chemotherapy, palliative care, and minimal delay to treatment/diagnosis. Logistic regression was used to adjust for confounders and identify factors associated with quality of care. Kaplan-Meier survival curves were compared using log-rank test. RESULTS One thousand seventy-two patients were identified. Survival improved in patients with private insurance compared to government-funded options [median overall survival (mOS) 57.8 vs. 21.2 months; P < .001]. Private insurance also correlated with earlier stage at diagnosis [stages I-II = 50.9% vs. 37.5%, stages III-IV = 37.7% vs. 49.1%, P < .001], increased chemotherapy use [44.2% vs. 37.1%, P < .001], and more surgical intervention [62.4% vs. 48.8%, P < .001]. Outcomes were inferior for Black Americans, including trend towards lower rate of surgical treatment [42% vs. 54%, P = .058] and worse survival in private insurance carriers [mOS 7.8 vs. 57.8 months, P = .021] and those with early stage disease [mOS 39.2 vs. 81.5 months, P = .045] compared to White counterparts. CONCLUSIONS Insurance status has the strongest impact on the quality of gastrointestinal oncologic care with negative synergistic negative effect of race for Black Americans. While governmental programs aim to improve equality of care, there remains significant disparity compared to private insurance. Moreover, private insurance doesn't correct disparity for Black Americans, suggesting the need to address racial imbalances in cancer care.

Abstract
PURPOSE Centralization of care to high-volume centers improves outcomes across urologic malignancies, but there exists a paucity of data for low-incidence cancers. Given the rarity of primary urethral cancer (UC) and the need for complex multidisciplinary treatment, we sought to evaluate differences in practice patterns and clinical outcomes across types of treating facilities. MATERIALS AND METHODS We identified all patients diagnosed with UC from 2004 to 2016 in the National Cancer Database. The Kaplan-Meier method was used to evaluate overall survival (OS) and multivariable Cox regression analysis was used to investigate independent predictors of OS. The chi-square test was used to analyze differences in practice patterns. RESULTS We identified 6,445 patients with UC. Median overall survival was 40.5 months (interquartile range 38.4-42.6). There was a significant difference in OS based upon facility type, and this difference remained significant on subgroup analysis for squamous cell carcinoma and urothelial carcinoma. Academic centers had superior OS on pairwise comparisons (all P< 0.05) and were associated with decreased risk of death, hazard ratio 0.858 (95% confidence interval 0.749-0.983). Academic centers had a significantly greater frequency of neoadjuvant/adjuvant chemotherapy and radiation (P < 0.001). Academic centers performed radical surgery in 34.1% of patients compared to 14.5% in community programs (P < 0.001), and regional lymphadenectomy in 31.6% of patients compared to 13.2% in community programs (P < 0.001). CONCLUSION There exist significant differences in survival for patients with UC based upon treating facility. Variations in practice patterns including multimodal treatment, radical surgery, and regional lymphadenectomy may contribute to the observed differences in clinical outcomes.

Abstract
OBJECTIVE To determine the influence of socioeconomic parameters on urinary stone surgeries. METHODS A retrospective cohort study analyzed patients undergoing urolithiasis surgery in our community network hospital in North Carolina from 2005-2018. RESULTS Of 7731 patients, 2160 (28%), 5,174 (67%), and 397 (5%) underwent SWL, URS, and PCNL, respectively. A higher proportion of Whites underwent URS (67%) and SWL (74%) than PCNL (56%); whereas a larger percentage of Blacks underwent PCNL (24%) than URS (20%) and SWL (15%) groups (P <.001). Private insurance payers were greater in the SWL (95%) group than URS (80%) and PCNL (81%) (P <.001). The distribution of median income was significantly different amongst the 3 surgeries with higher income classes overutilizing SWL and underutilizing PCNL compared to lower income classes (P <.001). In linear regression modeling, the proportion of SWL in a postal code was positively associated with median income (R2=0.55, P <.001); URS and PCNL were negatively associated with median income (R2=0.40, P <.001 and R2=0.41, P <.001, respectively). On multivariate logistic regression modeling, Blacks were significantly more likely to undergo PCNL than Whites (aOR 1.32, 95% CI 1.01-1.74 P <.050). Private insurance payers were more likely to undergo SWL (aOR 11.0, 95% CI 7.26-16.8, P <.0001) than public insurance payers. Patients in higher median income brackets are significantly less likely to undergo PCNL than those in the <$40,000 income bracket (P <.0001). CONCLUSION Our study suggests that socioeconomic status impacts urolithiasis surgical management, underscoring disparity recognition importance in endourologic care and ensuring appropriate surgical care regardless of socioeconomic status.

Abstract
PURPOSE Post-operative complication rates may vary among racial and/or ethnic groups and have not been previously described in individuals with spina bifida (SB) undergoing urologic surgery. The aim of this study was to compare in-hospital complication frequencies of individuals with SB following urologic surgery by race/ethnicity. METHODS The Nationwide Inpatient Sample was used to identify pediatric patients with SB who underwent inpatient urologic procedures. A pediatric cohort (<18 years old) with SB that underwent urologic surgery were assessed. All analyses report weighted descriptive statistics, outcomes, and race/ethnicity was the primary predictor variable. The primary outcome of interest was post-operative complications which were defined using NSQIP ICD-9 code definitions. Secondary analysis included length of stay (LOS), and encounter cost was estimated using the cost-to-charge ratio files provided by the Healthcare Cost and Utilization Project. RESULTS The unadjusted model showed no differences in complications, LOS, and cost. In the adjusted model there were no differences in complications, LOS, and cost between Black and White encounters. However, Hispanic ethnicity was associated with a 20%(95%CI: 4-40%) increase in LOS and 18%(95%CI: 2-35%, p = 0.02) increase in cost compared to White encounters. CONCLUSION There was no evidence of variation for in-hospital complication rates among racial/ethnic groups undergoing urologic surgery. Hispanic ethnicity was associated with higher costs and longer LOS in pediatric SB encounters.

Abstract
IMPORTANCE Bladder cancer is a common malignancy in women and is the fourth most common malignancy in men. Bladder cancer ranges from unaggressive and usually noninvasive tumors that recur and commit patients to long-term invasive surveillance, to aggressive and invasive tumors with high disease-specific mortality. OBSERVATIONS Advanced age, male sex, and cigarette smoking contribute to the development of bladder cancer. Bladder tumors can present with gross or microscopic hematuria, which is evaluated with cystoscopy and upper tract imaging depending on the degree of hematuria and risk of malignancy. Non-muscle-invasive tumors are treated with endoscopic resection and adjuvant intravesical therapy, depending on the risk classification. Enhanced cystoscopy includes technology used to improve the detection of tumors and can reduce the risk of recurrence. Patients with high-risk non-muscle invasive tumors that do not respond to adjuvant therapy with the standard-of-care immunotherapy, bacille Calmette-Guérin (BCG), constitute a challenging patient population to manage and many alternative therapies are being studied. For patients with muscle-invasive disease, more aggressive therapy with radical cystectomy and urinary diversion or trimodal therapy with maximal endoscopic resection, radiosensitizing chemotherapy, and radiation is warranted to curb the risk of metastasis and disease-specific mortality. Treatment of patients with advanced disease is undergoing rapid changes as immunotherapy with checkpoint inhibitors, targeted therapies, and antibody-drug conjugates have become options for certain patients with various stages of disease. CONCLUSIONS AND RELEVANCE Improved understanding of the molecular biology and genetics of bladder cancer has evolved the way localized and advanced disease is diagnosed and treated. While intravesical BCG has remained the mainstay of therapy for intermediate and high-risk non-muscle-invasive bladder cancer, the therapeutic options for muscle-invasive and advanced disease has expanded to include immunotherapy with checkpoint inhibition, targeted therapies, and antibody-drug conjugates.

Abstract
Aim: To understand physician visit patterns among patients with stage IV (including nonmetastatic [M0] and metastatic [M1] disease) urothelial carcinoma (UC) and understand factors associated with a timely referral to a medical oncologist and systemic treatment. Patients & methods: Retrospective analysis of Surveillance, Epidemiology and End Results-Medicare data. Results: First physician encounter was with a urologist (M0: 69%; M1: 53%) or primary care physician ([PCP]; M0: 19%, M1: 25%) for the majority of patients around UC diagnosis. After the index urologist encounter, most patients had a subsequent medical oncologist visit at a median of 52 days (M0: 69.5 days, M1: 33 days). In an adjusted model, older age, index PCP visit, higher comorbidities and M0 disease were negatively associated with a medical oncologist referral. Among those referred to a medical oncologist, older age, Hispanic or non-Hispanic Black race and not being married were negatively associated with subsequent chemotherapy receipt (p < 0.05). Conclusion: Many patients with advanced UC encounter multiple specialists during their disease course. Older patients or those with a first UC-related encounter with a PCP are less likely to be referred to medical oncology. Once referred to medical oncology, social determinants, including race and marital status, are relevant predictors of receiving chemotherapy.

Abstract
INTRODUCTION We aimed to identify preoperatively available patient variables associated with increased mortality within 30 and 90 days of radical cystectomy (RC) for localized urothelial carcinoma (UC), and to evaluate temporal trends in early mortality rates. METHODS We reviewed the National Cancer Database to identify patients who underwent RC for UC between 2006 and 2013. Preoperatively available patient-specific demographics and mortality rates at 30 and 90 days postoperatively were analyzed. Univariable and multivariable logistic regression analyses were performed to examine factors associated with 30- and 90-day mortality. RESULTS We identified 37 366 patients who underwent RC between 2006 and 2013. Overall mortality rates remained stable over time. From 2006-2013, 936 patients (2.5%) and 2554 patients (6.8%) died of any cause within 30 and 90 days post-RC, respectively. On multivariable analysis, increased age, higher clinical T and N stage, increased Charlson-Deyo comorbidity classification, African-American race, lower hospital volume, non-academic centers, lower patient income, and absence of insurance were each significantly associated with increased early mortality after RC (p<0.05). The protective effect of higher hospital volume was similar regardless of patient's age, clinical stage, or comorbidity status. CONCLUSIONS Our study identified patient-specific variables that are significantly associated with increased early mortality after RC. These findings can be used in counselling to identify ideal candidates for RC to decrease patient harm. Furthermore, early mortality rates after RC have remained stable over time, indicating that ongoing quality improvement is essential to improve outcomes.

Abstract
INTRODUCTION Current literature on perioperative and oncological outcomes following radical cystectomy among different racial groups is limited, especially among Hispanics and Asians. The objective of this study was to assess the impact of racial differences on perioperative and oncological outcomes in a large cohort of bladder cancer patients who underwent radical cystectomy. METHODS We retrospectively reviewed the records of 3293 patients who underwent radical cystectomy with curative intent at our institution between 1971 and 2017. Based on race, patients were categorized as Hispanic (n=190), Asian (n=145), African American (n=67), and Caucasian (n=2891). Baseline characteristics, pericystectomy complications, and oncological outcomes, including recurrence-free and overall survival, were compared between the racial groups. RESULTS Mean patient age was 68±10.6 years. Median followup was 10.28 years. Body masss index and American Society of Anesthesiologists scores were significantly higher in Hispanic and African American population, and smoking incidence was lower in Asian patients. Hispanics presented with significantly higher clinical stage and longer time interval from diagnosis to treatment (mean 85.5 vs. 75.4 days in Caucasians, p<0.001). Overall 90-day complication and readmission rates were higher in Hispanics (41.06% and 18.95%, respectively). Oncological outcomes, however, were comparable between different race groups. In multivariate analysis, pathological nodal status and lymphovascular invasion were independent predictors of oncological outcomes, but race was not. CONCLUSIONS In this very large, ethnically diverse patient cohort who underwent radical cystectomy with curative intent, pericystectomy complications were more common in Hispanics; however, race was not an independent predictor of long-term oncological outcome.

Abstract
PURPOSE OF REVIEW A review of the impact of several key patient characteristics on oncologic outcomes in bladder cancer (BC) summarized and analyzed in a narrative fashion. RECENT FINDINGS The bulk of the published literature suggests that females and blacks have poorer cancer-specific outcomes. Both groups tend to present with worse disease, which may be driven by differences in access to timely and quality care. Attempts to assess the association between smoking status and history and BC outcomes have been hindered by the quality and heterogeneity of the data, although several studies have linked smoking with higher rates of recurrence and poorer survival. Being married, particularly in men, may improve survival after radical cystectomy (RC). Limited data suggests that socioeconomic and education levels may be associated with poorer survival; however, the data is limited. A growing body of investigation suggests that there are significant differences in oncologic outcomes in BC patients based on race, gender, smoking status, socioeconomic status, and others. Further focus and investigation is needed to validate these findings, investigate the root cause of these differences, and offer solutions to mitigate them.

Does Health Insurance Modify the Association Between Race and Cancer-Specific Survival in Patients with Urinary Bladder Malignancy in the U.S.? INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16183393.

Abstract
Background: Scientific evidence on the effect of health insurance on racial disparities in urinary bladder cancer patients' survival is scant. The objective of our study was to determine whether insurance status modifies the association between race and bladder cancer specific survival during 2007-2015. Methods: The 2015 database of the cancer surveillance program of the National Cancer Institute (n = 39,587) was used. The independent variable was race (White, Black and Asian Pacific Islanders (API)), the main outcome was cancer specific survival. Health insurance was divided into uninsured, any Medicaid and insured. An adjusted model with an interaction term for race and insurance status was computed. Unadjusted and adjusted Cox regression analysis were applied. Results: Health insurance was a statistically significant effect modifier of the association between race and survival. Whereas, API had a lower hazard of death among the patients with Medicaid insurance (HR 0.67; 95% CI 0.48-0.94 compared with White patients, no differences in survival was found between Black and White urinary bladder carcinoma patients (HR 1.24; 95% CI 0.95-1.61). This may be due a lack of power. Among the insured study participants, Blacks were 1.46 times more likely than Whites to die of bladder cancer during the 5-year follow-up (95% CI 1.30-1.64). Conclusions: While race is accepted as a poor prognostic factor in the mortality from bladder cancer, insurance status can help to explain some of the survival differences across races.

Abstract
Urothelial cancer of the bladder (UCB) is usually a disease of the elderly. The influence of age on oncological outcomes remains controversial. This study aims to investigate the impact of age on UCB outcomes in Europe focusing particularly on young and very young patients. We collected data of 669 UCB patients treated with RC at our tertiary care center. We used various categorical stratifications as well as continuous age to investigate the association of age and tumor biology as well as endpoints with descriptive statistics and Cox regression. The median age was 67 years and the mean follow-up was 52 months. Eight patients (1.2%) were ≤40 years old and 39 patients (5.8%) were aged 41-50 years, respectively. In multivariable analysis, higher continuous age and age above the median were independent predictors for disease recurrence, and cancer-specific and overall mortality (all p-values ≤ 0.018). In addition, patients with age in the oldest tertile group had inferior cancer-specific and overall survival rates compared to their younger counterparts. Young (40-50 years) and very young (≤40 years) patients had reduced hazards for all endpoints, which, however, were not statistically significant. Age remains an independent determinant for survival after RC. Young adults did, however, not have superior outcomes in our analyses. Quality of life and complications are endpoints that need further evaluation in patients undergoing RC.

Abstract
BACKGROUND Recent advances in genomic and genetic technologies have facilitated better health outcomes for urologic cancer patients. Genomic and genetic heterogeneity may contribute to differences in tumor biology and urologic cancer burden across various populations. OBJECTIVE To examine how emerging genomic and genetic biomarkers, self-reported race, and ancestry-informative markers are associated with kidney, prostate, and bladder cancer outcomes. RESULTS Genomic and genetic alterations found in African American kidney cancer patients included distinct somatic mutations, somatic copy number alterations, chromosomal instability, germ-line risk alleles, and germ-line genetic variants. These changes correlated with improved risk prediction, prognosis, and survival; and a predicted decrease in response to targeted therapies. SNP risk alleles and ancestry-informative markers were associated with improved risk prediction in prostate cancer patients of both African and European descent. AKT activation suggest differential response to AKT-targeted therapies in African American, Asian American, and Tunisian bladder cancer patients. Both self-reported race and genetic ancestry predicted urologic cancer risk prediction. CONCLUSION Precision medicine approaches that integrate population-specific genomic and genetic information with other known urologic cancer-specific characteristics can improve outcomes and be leveraged to reduce cancer health disparities. Further investigations are necessary to identify novel genomic biomarkers with clinical utility.

Abstract
INTRODUCTION Metabolomics is a chemical process, involving the characterization of metabolites and cellular metabolism. Recent studies indicate that numerous metabolic pathways are altered in bladder cancer (BLCA), providing potential targets for improved detection and possible therapeutic intervention. We review recent advances in metabolomics related to BLCA and identify various metabolites that may serve as potential biomarkers for BLCA. Areas covered: In this review, we describe the latest advances in defining the BLCA metabolome and discuss the possible clinical utility of metabolic alterations in BLCA tissues, serum, and urine. In addition, we focus on the metabolic alterations associated with tobacco smoke and racial disparity in BLCA. Expert commentary: Metabolomics is a powerful tool which can shed new light on BLCA development and behavior. Key metabolites may serve as possible markers of BLCA. However, prospective validation will be needed to incorporate these markers into clinical care.

Abstract
OBJECTIVE Length of hospital stay for patients following radical cystectomy is an important determinant for improved quality of care. We sought to develop and validate a predictive model for length of hospital stay following radical cystectomy. METHODS Patients aged 66 to 90 years diagnosed with clinical stage T2-4a muscle-invasive bladder cancer who underwent radical cystectomy were included from January 1, 2002 through December 31, 2011 using the Surveillance, Epidemiology, and End Results (SEER)-Medicare data. Linear regression analyses were used to develop and validate a predictive model for length of hospital stay. RESULTS A total of 2,448 patients met inclusion criteria. After random assignment, 1,224 patients were included in the discovery cohort and 1,224 patients included in the validation cohort. The cohorts were well balanced with no significant difference in any of the preoperative variables. A best model was developed using marital status, Surveillance, Epidemiology, and End Results (SEER) region, clinical stage, Charlson comorbidity index, logarithm of hospital cystectomy volume, and use of neoadjuvant chemotherapy in a backward selection to predict the length of stay. There was robust internal validation (sum square error (SSE): 258.1 vs. predicted sum of squares (PRESS): 264.0 at SLS = 0.10), consistent with the external validation (average square error (ASE): discovery (0.248) vs. validation (0.258)) cohort. The strength of the model in predicting length of stay for the entire cohort was (R2 = 0.048). CONCLUSION In this large population-based study, we developed and validated a model to predict length of hospital stay following radical cystectomy. Identification of at-risk patients for prolonged hospital stay may aid in targeted interventions to reduce length of stay, improve quality of care, and decrease healthcare costs.
