IMPACT OF DOXORUBICIN ON SURVIVAL IN ADVANCED OVARIAN-CANCER

Purpose: Our study examined the impact of the addition of doxorubicin to ovarian cancer regimens in general, while removing the confounding influence of other drugs. Materials and Methods: We performed an overview using the data from two large analyses, the Advanced Ovarian Cancer Trialists Group (AOCTG [Br Med J 303:884-893, 1991] and Williams et al [Seminars in Oncol 19:120-128, 1992 (suppl 2)]) and the Ovarian Cancer Meta-Analysis Project (OCMP [J Clin Oncol 9:1668-1674, 1991]). Results: Our data suggest that the addition of doxorubicin significantly improves survival (hazards ratio, 0.85; 95% confidence interval [CI], 0.76 to 0.95; P = .003) and that the size of this benefit is of a similar magnitude to that of platinum. Conclusion: The implication of our results is that the basic drugs for the standard treatment of advanced ovarian cancer should be a combination of platinum and doxorubicin. The addition of an alkylating agent may add toxicity and lead to a dose reduction of these two drugs. In view of recent date on combination therapy with paclitaxel and platinum, it would be appropriate to compare this regimen with a combination of doxorubicin and platinum.
