Use of psychotropic drugs among older patients with bladder cancer in the United States.

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.

Proximity to Oil Refineries and Risk of Cancer: A Population-Based Analysis.

BACKGROUND: The association between proximity to oil refineries and cancer rate is largely unknown. We sought to compare the rate of cancer (bladder, breast, colon, lung, lymphoma, and prostate) according to proximity to an oil refinery in Texas. METHODS: A total of 6 302 265 persons aged 20 years or older resided within 30 miles of an oil refinery from 2010 to 2014. We used multilevel zero-inflated Poisson regression models to examine the association between proximity to an oil refinery and cancer rate. RESULTS: We observed that proximity to an oil refinery was associated with a statistically significantly increased risk of incident cancer diagnosis across all cancer types. For example, persons residing within 0-10 (risk ratio [RR] = 1.13, 95% confidence interval [CI] = 1.07 to 1.19) and 11-20 (RR = 1.05, 95% CI = 1.00 to 1.11) miles were statistically significantly more likely to be diagnosed with lymphoma than individuals who lived within 21-30 miles of an oil refinery. We also observed differences in stage of cancer at diagnosis according to proximity to an oil refinery. Moreover, persons residing within 0-10 miles were more likely to be diagnosed with distant metastasis and/or systemic disease than people residing 21-30 miles from an oil refinery. The greatest risk of distant disease was observed in patients diagnosed with bladder cancer living within 0-10 vs 21-30 miles (RR = 1.30, 95% CI = 1.02 to 1.65), respectively. CONCLUSIONS: Proximity to an oil refinery was associated with an increased risk of multiple cancer types. We also observed statistically significantly increased risk of regional and distant/metastatic disease according to proximity to an oil refinery.

Impact of Alzheimer's disease and related dementia diagnosis following treatment for bladder cancer.

OBJECTIVES: Our objective was to assess the incidence of Alzheimer's Disease and related dementia diagnosis following treatment for muscle-invasive bladder cancer and impact on survival outcomes. MATERIALS AND METHODS: A total of 4814 patients diagnosed with clinical stage T2-T4a, N0, M0 bladder cancer between January 1, 2002 to December 31, 2011 using the Surveillance, Epidemiology, and End Results (SEER)-Medicare database were identified. Alzheimer's disease and related dementia diagnosis was identified using International Statistical Classification of Disease-Ninth Edition outpatient and inpatient codes. Incidence of dementia following treatment were calculated and reported as dementia cases per 10,000 person-years. Cox proportional hazards models were used to assess the impact of dementia on survival outcomes. RESULTS: Of the 4814 patients, 2403 (49.9%) underwent radical cystectomy (RC) and 2411 (50.1%) underwent radiotherapy (RTX) and/or chemotherapy (CTX). Overall, 837 (17.4%) patients developed Alzheimer's disease and related dementia following bladder cancer treatment. There was no significant difference in the incidence of Alzheimer's disease and related dementia following either treatment. Patients diagnosed with Alzheimer's disease and related dementia had worse overall (Hazard Ratio (HR), 2.64; 95% Confidence Interval (CI), 2.41-2.89) and cancer-specific (HR, 2.45; 95% CI, 2.18-2.76) survival than those without a dementia diagnosis following treatment. CONCLUSION: While we observed no difference in new-onset Alzheimer's disease and related dementia diagnosis following RC or RTX and/or CTX, patients with a Alzheimer's and related dementia diagnosis was associated with worse overall and cancer-specific survival. These findings have important implications for screening and the development of targeted interventions for improving outcomes in older adults following complex cancer treatments, as observed in this bladder cancer population.

Comparison of Costs of Radical Cystectomy vs Trimodal Therapy for Patients With Localized Muscle-Invasive Bladder Cancer.

Importance: Earlier studies on the cost of muscle-invasive bladder cancer treatments lack granularity and are limited to 180 days. Objective: To compare the 1-year costs associated with trimodal therapy vs radical cystectomy, accounting for survival and intensity effects on total costs. Design, Setting, and Participants: This population-based cohort study used the US Surveillance, Epidemiology, and End Results-Medicare database and included 2963 patients aged 66 to 85 years who had received a diagnosis of clinical stage T2 to T4a muscle-invasive bladder cancer from January 1, 2002, through December 31, 2011. The data analysis was performed from March 5, 2018, through December 4, 2018. Main Outcomes and Measures: Total Medicare costs within 1 year of diagnosis following radical cystectomy vs trimodal therapy were compared using inverse probability of treatment-weighted propensity score models that included a 2-part estimator to account for intrinsic selection bias. Results: Of 2963 participants, 1030 (34.8%) were women, 2591 (87.4%) were white, 129 (4.4%) were African American, and 98 (3.3%) were Hispanic. Median costs were significantly higher for trimodal therapy than radical cystectomy in 90 days ($83 754 vs $68 692; median difference, $11 805; 95% CI, $7745-$15 864), 180 days ($187 162 vs $109 078; median difference, $62 370; 95% CI, $55 581-$69 160), and 365 days ($289 142 vs $148 757; median difference, $109 027; 95% CI, $98 692-$119 363), respectively. Outpatient care, radiology, medication expenses, and pathology/laboratory costs contributed largely to the higher costs associated with trimodal therapy. On inverse probability of treatment-weighted adjusted analyses, patients undergoing trimodal therapy had $136 935 (95% CI, $122 131-$152 115) higher mean costs compared with radical cystectomy 1 year after diagnosis. Conclusions and Relevance: Compared with radical cystectomy, trimodal therapy was associated with higher costs among patients with muscle-invasive bladder cancer. The differences in costs were largely attributed to medication and radiology expenses associated with trimodal therapy. Extrapolating cost figures resulted in a nationwide excess spending of $468 million for trimodal therapy compared with radical cystectomy for patients who received a diagnosis of bladder cancer in 2017.

Comparing Survival Outcomes and Costs Associated With Radical Cystectomy and Trimodal Therapy for Older Adults With Muscle-Invasive Bladder Cancer.

Importance: Radical cystectomy is the guidelines-recommended treatment of muscle-invasive bladder cancer, but a resurgence of trimodal therapy has occurred. Limited comparative data are available on outcomes and costs attributable to these 2 treatments. Objective: To compare the survival outcomes and costs between trimodal therapy and radical cystectomy in older adults with muscle-invasive bladder cancer. Design, Setting, and Participants: This population-based cohort study used data from the Surveillance, Epidemiology, and End Results-Medicare linked database. A total of 3200 older adults (aged ≥66 years) with clinical stage T2 to T4a bladder cancer diagnosed from January 1, 2002, to December 31, 2011, and with claims data available through December 31, 2013, were included in the analysis. Patients who received radical cystectomy underwent either only surgery or surgery in combination with radiotherapy or chemotherapy. Patients who received trimodal therapy underwent transurethral resection of the bladder followed by radiotherapy and chemotherapy. Propensity score matching by sociodemographic and clinical characteristics was used. Data analysis was performed from August 1, 2017, to March 11, 2018. Main Outcomes and Measures: Overall survival and cancer-specific survival were evaluated using the Cox proportional hazards regression model and the Fine and Gray competing risk model. All Medicare health care costs for inpatient, outpatient, and physician services within 30, 90, and 180 days of treatment were compared. The total amount spent nationwide was estimated, using 180-day medical costs between treatments, by the total number of new cases of muscle-invasive bladder cancer in the United States in 2011. Results: Of the 3200 patients who met the inclusion criteria, 2048 (64.0%) were men and 1152 (36.0%) were women, with a mean (SD) age of 75.8 (6.0) years. After propensity score matching, 687 patients (21.5%) underwent trimodal therapy and 687 patients (21.5%) underwent radical cystectomy. Patients who underwent trimodal therapy had significantly decreased overall survival (hazard ratio [HR], 1.49; 95% CI, 1.31-1.69) and cancer-specific survival (HR, 1.55; 95% CI, 1.32-1.83). No differences in costs at 30 days were observed between trimodal therapy ($15 233 in 2002 vs $18 743 in 2011) and radical cystectomy ($17 990 in 2002 vs $21 738 in 2011). However, median total costs were significantly higher with trimodal therapy than with radical cystectomy at 90 days ($80 174 vs $69 181; median difference, $8964; Hodges-Lehmann 95% CI, $3848-$14 079) and at 180 days ($179 891 vs $107 017; median difference, $63 771; Hodges-Lehmann 95% CI, $55 512-$72 029). Extrapolating these figures to the total US population revealed $335 million in excess spending for trimodal therapy compared with the less costly radical cystectomy ($492 million) for patients who received a muscle-invasive bladder cancer diagnosis in 2011. Conclusions and Relevance: Trimodal therapy was associated with significantly decreased overall survival and cancer-specific survival as well as $335 million in excess spending in 2011. These findings have important health policy implications regarding the appropriate use of high value-based care among older adults with invasive bladder cancer who are candidates for either radical cystectomy or trimodal therapy.

Impact of psychiatric illness on decreased survival in elderly patients with bladder cancer in the United States.

BACKGROUND: Treatments for muscle-invasive bladder cancer are multimodal, complex, and often carry significant risks of physical and psychological morbidity. The objectives of this study were to define the incidence and types of psychiatric illnesses diagnosed after treatment and to determine their impact on survival outcomes. METHODS: In total, 3709 patients who were diagnosed with clinical stage T2 through T4a bladder cancer from January 1, 2002, to December 31, 2011, from the Surveillance, Epidemiology, and End Results-Medicare were analyzed. Multivariable analysis and Cox proportional-hazards models were used to determine the predictors associated with psychiatric diagnosis and impact on survival outcomes. RESULTS: Of 3709 patients, 1870 (50.4%) were diagnosed with posttreatment psychiatric disorders. Patients who underwent radical cystectomy were identified as being at significantly greater risk of having a posttreatment psychiatric illness compared with those who received radiotherapy and/or chemotherapy (hazard ratio [HR], 1.19; 95% confidence interval [CI], 1.07-1.31; P = .001). In adjusted analyses, diagnosis of a psychiatric disorder resulted in significantly worse overall survival (HR, 2.80; 95% CI, 2.47-3.17; P < .001) and cancer-specific survival (HR, 2.39; 95% CI, 2.05-2.78; P < .001). CONCLUSIONS: One-half of patients with muscle-invasive bladder cancer who underwent treatment were diagnosed with a psychiatric disorder, which resulted in worse survival outcomes compared with patients who did not have a posttreatment psychiatric diagnosis. This information can be used to inform interventions to educate patients with muscle-invasive bladder cancer regarding the impact of different treatments on mental health.
