Purpose

To estimate the cost-effectiveness from a French payer perspective of CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) alone compared with CHOP plus rituximab (R-CHOP) for treatment of patients with diffuse large B-cell lymphoma.

Methods

Mean patient survival, days of hospitalization, and chemotherapy costs during treatment were estimated from a Phase III trial in France, Belgium, and Switzerland. Survival during the trial was estimated using the Kaplan–Meier method; survival beyond the trial period was projected based on mortality rates from the Scottish and Newcastle Lymphoma Group database. French diagnosis-related group (DRG) payment schedules were applied to trial data to estimate cost of adverse events and drug administration. We estimated survival and cost-effectiveness [the incremental cost per quality-adjusted life-year (QALY) gained] from 4 years (median clinical trial follow-up period) to 15 years, discounted at a fixed annual rate of 3%. We used published patient preferences. We converted currency to euros, based on 2003 exchange rates.

Results

R-CHOP resulted in a 20.6% relative increase in complete response rate (absolute increase from 63% to 76%), and a 31% decrease in risk of death at 4 years (95% CI 8–49%). Over a 15-year time horizon, mean overall survival (OS) duration was estimated to be 6.90 years for R-CHOP and 5.74 years for CHOP, a mean increase in OS of 1.16 years (or 1.07 QALYs). Total direct medical costs were €13,170 higher with R-CHOP, with an incremental cost-effectiveness ratio of €12,259 per QALY gained.

Conclusion

R-CHOP significantly increases mean OS up to 4 years compared with CHOP, and its cost-effectiveness ratio compares favorably with other oncology treatments in widespread use.
