High-dose platinum chemotherapy in advanced ovarian cancer: a phase II study.
From September 1986 to November 1988, 38 patients with previously untreated ovarian cancer, FIGO stages III and IV, were allocated to a study testing the efficacy of high-dose platinum delivered as combined carboplatin and cisplatin. The regimen was as follows: Day 1, 250-350 mg/m2 carboplatin and 500 mg/m2 cyclophosphamide, Day 15, 100 mg/m2 cisplatin. Overall clinical response was 60%, and complete pathologic response, verified at second-look laparotomy, was 24%. Median survival was 17 months and 3-year survival 27%. The results are similar to those obtained by a standard dose of cisplatin, cyclophosphamide, and doxorubicin. Myelotoxicity was dose limiting. After receiving four cycles, 44% of patients had grade 3 or 4 leucopenia and 65% had grade 3 or 4 thrombopenia. Despite this, dose intensity of combined cisplatin and carboplatin was between 30 and 45 mg/m2/week, expressed as cisplatin by assuming that 1 mg cisplatin equals 4 mg of carboplatin. A correlation between dose intensity and response was not found. In conclusion the study showed that the regimen is feasible, but very myelotoxic. The results were not superior to those obtained by combination chemotherapy using standard doses of cisplatin.
