Abstract

Background: The GOELAMS 072 study showed that first-line high-dose chemotherapy (HDT) with peripheral blood stem cell transplant (PBSCT) support was superior to the standard chemotherapy regimen (cyclophosphamide, doxorubicin, vincristine and prednisone; CHOP) in adults with aggressive non-Hodgkin’s lymphoma (NHL).

Objective: The aim of the study was to evaluate the pharmacoeconomic profile of HDT with PBSCT support relative to standard CHOP therapy as first-line treatment in adults with aggressive NHL.

Methods: We performed a cost-effectiveness analysis from the French Public Health Insurance perspective, restricted to hospital costs (€, year 2008 values). The clinical effectiveness criterion was censured overall survival (OS) difference after a median follow-up of 4 years for the entire cohort. A total of 197 patients were included (CHOP, n = 99; HDT, n = 98). Uncertainty was assessed using non-parametric bootstrap simulations and various scenario analyses.

Results: Five-year OS did not differ significantly between groups for the entire cohort. Nevertheless, subgroup analyses appeared to be more relevant for decision making: among patients with a high-intermediate risk according to the age-adjusted International Prognostic Index (IPI), HDT yielded a significantly higher 5-year OS than CHOP (74% vs 44%; p = 0.001). Among these patients, the mean censured OS survival, adjusted for time discounting and quality of life (QOL), increased with HDT by 1.20 years (95% CI 1.19, 1.21). The cost per life-year saved with HDT was estimated as h34 315 (95% CI 32 683, 35 947) in this subgroup.

Conclusion: Results suggested thatHDT with PBSCT supportmight be considered a cost-effective strategy among patients with high-intermediate-risk NHL according to the age-adjusted IPI. Its place and its cost effectiveness potential versus, or in combination with, rituximab still need further research.
