5026 Background: To investigate the clinical and economic disease burden for patients (pts) with non-muscle invasive bladder cancer (NMIBC), muscle invasive bladder cancer (MIBC), and metastatic urothelial carcinoma (mUC) using a Swedish bladder cancer registry. Methods: Pts diagnosed with bladder cancer in the Stockholm Gotland region between 2005-2013 were included and followed until May 31, 2015 or until death. MIBC was classified if a T, N, M at diagnosis was T2, T3, T4, N1, N2, N3, or M1, otherwise pts were classified as NMIBC. All diagnostic and therapeutic interventions were captured and differentiated. Inpatient and outpatient healthcare resource utilization (days) and associated costs (US $) were also analyzed. Results: 3587 bladder cancer pts were identified (NMIBC-2728; MIBC-859) with a median observation time of 49.7 (Q1-Q3: 27.8-78.7) versus 17.2 (Q1-Q3: 6.5-39.3) months. 5-year survival for patients with NMIBC at diagnosis was 71.3% (95% CI; 69.5-73.3) and 26.4% (95%CI; 23.4-29.8) for MIBC. By year 1, survival for MIBC-T2, T3, and T4 was 66%, 41.7%, and 28.4%, respectively. Progression from NMIBC to MIBC was estimated in 19.4% (528/2728) of pts. In year 1, 84% (2,275/2,728) of TURBT procedures were performed on NMIBC pts. Over the next 2-10 years of follow-up, 11,035 repeat TURBT procedures were undertaken in this cohort. In the 859 MIBC pts, 607 TURBT procedures and 333 radical cystectomies occurred in year 1. In the same cohort, 28.3% (243/859), 15.5% (78/505), and 8.6% (29/338) received systemic chemotherapy in years 1, 2, and 3, respectively. Total health resource utilization (HRU) cost for the NMIBC and MIBC cohorts is provided in Table. Median HRU cost per person-year was estimated at $30,470 for MIBC versus $9,228 for NMIBC in year 1. For MIBC-T2, T3, and T4, median cost per person-year was $30,154, $33,917, and $38,959 in year 1, respectively. Conclusions: This retrospective analysis accomplished its primary purpose to provide a real-world understanding for the clinical and economic impact of bladder cancer over a 10-year period when treatment interventions were relatively consistent. Total HRU Costs for Patients with NMIBC and MIBC per Follow-up Year (Years 1 to 5). [Table: see text]
