Melphalan for the treatment of patients with recurrent epithelial ovarian cancer

The purpose of this study was to determine the response to melphalan in patients with recurrent epithelial ovarian cancer after platinum-based therapy. This retrospective observational study analyzed 10 patients with recurrent epithelial ovarian carcinoma treated with melphalan between August 1995 and April 2001. All had received primary platinum-based therapy. Nine of the 10 patients had chemosensitive disease. All but one patient had received one or more second-line therapies prior to melphalan. The median time to recurrence after first-line therapy was 26 months (range, 3-68). Treatment with melphalan resulted in 2 (20%) complete responses and 1 (10%) partial response (response rate, 30%; 95% CI 8%, 65%). The median progression-free interval after initiation of melphalan therapy was 8 months (range, 3-23). The most common side effects were grade I thrombocytopenia (20% of courses) and grade 11 leukopenia (18% of courses). The use of melphalan as palliative chemotherapy in patients with recurrent ovarian cancer results in response rates similar to those reported with other more expensive agents. Melphalan at the doses reported here has a favorable toxicity profile.
