We used simulations to compare the benefits and costs of major guidelines for surveillance of high-risk NMIBC. METHODS: A Monte-Carlo simulation was created to model the 10-year outcomes and costs of 5 guidelines for surveillance of 10,000 patients diagnosed with carcinoma in situ (CIS), high-grade (HG) Ta or T1 NMIBC at age 70 years: the American Urological Association (AUA), National Comprehensive Cancer Network (NCCN), European Association of Urology (EAU), Canadian Urological Association (CUA), and National Institute for Health and Care Excellence (NICE). We evaluated separately the most intense (denoted as AUAi and CUAi) and relaxed (AUAr and CUAr) surveillance regimens within the range of surveillance frequencies allowed by the AUA and CUA guidelines. RESULTS: For HGT1, absolute differences in 10-year cumulative incidence (CI) of muscle invasive bladder cancer (MIBC) were ≤0.4% across guidelines (Table 1). Differences across guidelines were minimal in cancer-specific survival (CSS) and overall survival (OS). For CIS and HgTa, greater absolute differences in MIBC CI were seen across guidelines (CIS: ≤0.8%; HgTa: ≤1.3%) and within guidelines (CIS: 0.6% for both AUA and CUA; HgTa: 0.9% for AUA, 0.6% for CUA). For both CIS and HGTa, absolute differences across guidelines were ≤0.5% in CSS and ≤0.2% in OS. In cost-effectiveness analysis, the surveillance regimens all achieved similar health utilities; the less stringent ones such as CUAr and NICE led to cost savings (Table 2). Under conventional cost-effectiveness thresholds, CUAr was the most cost-effective option for HGT1 and CIS, and NICE for HGTa. CONCLUSIONS: Oncological outcomes were highly similar across guidelines for surveillance of HGT1. Small to moderate differences were noted across and within guidelines for surveillance of CIS and HgTa. More stringent surveillance regimens did not achieve enough health utility benefits to be found cost-effective versus less stringent regimens.
