Résumé
OBJECTIVE: The cardiotoxicity of anthracyclines remains a key problem in patients with aggressive non-Hodgkin's lymphoma (NHL). With regard to the actual long-term prognosis of aggressive NHL, the development of cardioprotective strategies is mandatory for these patients. A cost-effectiveness analysis was carried out to determine the potential economic profile of dexrazoxane or liposome-encapsulated doxorubicin in patients with aggressive NHL treated with a CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone) as first-line therapy. METHODS: A decision-analysis model described clinical events and economic consequences for theoretical patients who were to receive eight consecutive cycles of a CHOP regimen containing 50 mg/m(2) of doxorubicin as first-line chemotherapy. The timeframe of the model was the patient's lifetime. The probabilities were related to the cumulative dose of doxorubicin and age. The study was carried out from the perspective of the French healthcare system. Patients entered the model at 'choose' node: no cardioprotection versus cardioprotection with dexrazoxane or liposome-encapsulated doxorubicin. The model was based on a retrospective epidemiological study and on published data. The clinical end-point was life expectancy. Direct medical costs related to the cardioprotection and the treatment of congestive heart failure were considered. Monetary values for French prices in the year 2002 were used. Several univariate sensitivity analyses were carried out with varying clinical and economic parameters. RESULTS: Per 100 patients, the two cardioprotective strategies provided similar benefits that were estimated as 24.5 and 13.4 life-years in 60- and 40-year-old patients, respectively. The cost per life-year saved with dexrazoxane was estimated as euro6931 and euro15 599 in 60- and 40-year-old patients, respectively, and euro22 940 and euro44 982, respectively, with liposome-encapsulated doxorubicin. Several sensitivity analyses showed the robustness of the model. CONCLUSION: The results suggest the potential clinical and economic usefulness of cardioprotective therapies in patients with aggressive NHL. Prospective studies are needed to confirm these findings.
