What's known on the subject? and What does the study add?
Bladder cancer is one of the costliest malignancies to treat throughout the life of a patient. The most cost-effective management for low–risk non-muscle-invasive bladder cancer is not known.
The current study shows that employing cystoscopic office fulguration for low-risk appearing bladder cancer recurrences can materially impact the cost-effectiveness of therapy. In a follow-up protocol where office fulguration is routinely employed for low-risk bladder cancers, peri-operative intravesical chemotherapy may not provide any additional cost-effectiveness benefit.
- • To examine the cost-effectiveness of fulguration vs transurethral resection of bladder tumour (TURBT) with and without perioperative intravesical chemotherapy (PIC) for managing low-risk carcinoma not invading bladder muscle (NMIBC). Low-risk NMIBC carries a low progression rate, lending support to the use of office-based fulguration for small recurrences rather than traditional TURBT.
MATERIALS AND METHODS
- • A Markov state transition model was created to simulate treatment of NMIBC with vs without PIC, with recurrence treated by formal TURBT vs treatment with fulguration.
- • Costing data were obtained from the Medicare Resource Based Relative Value Scale.
- • Data regarding the success of PIC were obtained from the peer-reviewed literature, as were corresponding utilities for bladder cancer-related procedures.
- • Sensitivity analyses were performed.
- • At 5-year follow-up, a strategy of fulguration without PIC was the most cost-effective (mean cost-effectiveness = US $654.8/quality-adjusted life year), despite a lower recurrence rate with PIC.
- • Both fulguration strategies dominated each TURBT strategy.
- • Sensitivity analysis showed that fulguration without PIC dominated all other strategies when the recurrence rate after PIC was increased to ≥14.2% per year.
- • Similarly, the cost-effectiveness of TURBT becomes more competitive with fulguration when the total cost of TURBT declines < US $1175.
- • The present study shows that fulguration without PIC was the most cost-effective strategy for treating low-risk NMIBC.
- • The effectiveness of PIC and the cost of TURBT can materially impact the cost-effectiveness of the different management strategies.
- • These results should be considered in treatment decisions in the context of preserving oncological control.
