Pharmacoeconomic profile of paclitaxel as a first-line treatment for patients with advanced ovarian carcinoma. A lifetime cost-effectiveness analysis.

Abstract

BACKGROUND. Analysis of published survival curves has recently been proposed as a method for conducting incremental cost-effectiveness analysis in which two treatments are compared with each other in terms of cost per year of life gained. In patients with advanced ovarian carcinoma, the combination of paclitaxel and cisplatin has been reported to improve survival more significantly than standard therapy with cyclophosphamide and cisplatin. However, the high cost of paclitaxel indicates a need for an evaluation of the pharmacoeconomic profile of these treatments. METHODS. The authors conducted an incremental cost-effectiveness analysis to assess the paclitaxel-based regimen in terms of cost per year of life gained. The analysis utilized data from a published controlled long term trial involving 184 patients treated with paclitaxel and cisplatin and 202 patients treated with cyclophosphamide and cisplatin. Gompertz’ law was employed to obtain the lifetime estimate of the years gained by patients given the first treatment in comparison with patients given the
