ABSTRACT
OBJECTIVE:
To compare the cost-utility of initial management of high-grade T1 non-muscle invasive bladder cancer (HGT1 NMIBC) with intravesical BCG vs immediate radical cystectomy. High-risk NMIBC patients may climb a costly ladder of treatments, culminating in radical cystectomy for oncologic or symptomatic benefit in up to one-third. This high healthcare resource utilization presents a challenging dilemma in balancing sufficiently aggressive management with cost, toxicity, and quality-of-life.METHODS:
Cost-utility of initially managing HGT1 with intravesical BCG and early radical cystectomy with ileal conduit urinary diversion was compared using decision-analytic Markov models. Five-year oncologic outcomes, adverse event rates, and published utility values were extracted from literature. Costs were calculated from a US Medicare perspective in 2021 US dollars. Sensitivity analysis identified drivers of cost and break-even points for recurrence and progression.RESULTS:
Mean costs were $26,093 for intravesical BCG and $39,720 for immediate radical cystectomy, though cystectomy generated a gain of 2.2 quality-adjusted life years (QALYs) compared to intravesical BCG. Immediate cystectomy was a more cost-effective management strategy for HGT1 NMIBC with an incremental CE ratios (ICER) of $7120/QALY. The costs associated with cystectomy, TURBT, and BCG toxicity had the greatest impact on ICER. One-way sensitivity analysis demonstrated that intravesical BCG became a cost-effective management strategy if the 5-year recurrence rate of HG T1 was less than 56% or the 5-year progression rate to MIBC was less than 4%.CONCLUSION:
At current prices, treatment of high-grade T1 NMIBC with early radical cystectomy is more cost-effective management strategy than initial treatment with intravesical BCG.
