Abstract

Objective. The aim of the study was to analyze the benefit/toxicity profile of a second-line treatment with carboplatin alone or carboplatin plus another non-cross-resistant drug (epidoxorubicin) in ovarian cancer patients sensitive to cisplatin-based chemotherapy at first-line treatment. Methods. We conducted a randomized clinical trial. Women with epithelial ovarian cancer FIGO Stage II-IV who had a complete or partial response to first-line treatment with cisplatin or carboplatin-based regiments and subsequently progressed or relapsed more than 6 months after discontinuation of first-line treatment were eligible for the study. A total of 190 subjects entered the study. They were randomly allocated to either 300 mg/m 2 of carboplatin every 28 days for five cycles (95 patients) or 120 mg/m 2 of epidoxorubicin and 300 mg/m 2 of carboplatin every 28 days for five cycles (95 patients). Results. A complete response was reported, respectively, in 32 (36%) women allocated to carboplatin alone and in 28 (31.8%) of those allocated to carboplatin plus epidoxorubicin. The corresponding figures for partial response were 18 (20.2%) and 26 (29.9%). Comparing the frequency of complete response, partial response, no change, and progression, the differences between the two groups were not significant (X 2 3 5.10, P = 0.16). The median duration of response was 16 months in the carboplatin alone and 20 months in the carboplatin plus epidoxorubicin group (P = not significant). The 3-year percentage of survival was 29% in the carboplatin alone and 42% in the carboplatin plus epidoxorubicin group; this difference was not statistically significant. The frequency of leukopenia, anemia, and thrombocytopenia grade 3-4 was higher in the epidoxorubicin plus carboplatin than in the carboplatin alone group. Alopecia G3 was present in 88% of women treated with epidoxorubicin plus carboplatin. Conclusions. The general results of this study do not show any marked differences in response to second-line treatment among women treated with single-agent (carboplatin) or multiagent (carboplatin plus epidoxorubicin) schedules. Toxicity, particularly hematological, was more relevant in women treated with the multiagent schedule.
