OBJECTIVE: This study was designed to evaluate the efficacy and toxicity of topotecan hydrochloride, used singly or combined with other drugs in patients with recurrent advanced ovarian cancer.
METHODS: Eighteen ovarian cancer patients who had received cytoreductive operation 1 to 3 times and 8 to 18 courses of chemotherapy but still failed in DDP-based(86.3%) and Taxol-based(32.7%) as well as combined DDP and Taxol-based(30.7%) chemotherapy, were divided into 3 groups: 1. Topotecan 1.2 mg/m2 q.d.i.v. for 5 consecutive days every 3 weeks for a total of 6 patients and 14 courses. 2. Topotecan 0.7 mg/m2 q.d.i.v. for 5 consecutive days and cis-platin 20 mg/m2 q.d.i.v. for 3 consecutive days over 4 weeks and 3. Topotecan 0.7 mg/m2 q.d.i.v. for 4 consecutive days and taxol 100 mg/m2 q.d.i.v. for one day as well as cis-platin 20 mg/m2 q.d.i.v. for 3 consecutive days totalling 12 patients and 27 courses. All together 18 courses, median 2.7 courses, were given.
RESULTS: All 18 patients were evaluable. PR was achieved in 3 patients with a response rate of 16.7%. The main adverse effects were hematological toxicity, lasting for 3-27 days. Ten (55.6%) patients developed leucocytopenia Grade III-IV which occurred in 16(33.3%) courses. Six(33.3%) patients developed thrombocytopenia Grade III-IV which occurred in 8(16.7%) courses. Six(33.3%) patients developed RBC reduction Grade III which occurred in 8(16.7%) courses. Peripheral nerve inflammation was most serious in the non-hematologic toxicity.
CONCLUSION: Topotecan is effective in recurrent advanced ovarian cancer patients who have failed in DDP or/and taxol-based regimes. Topotecan combined with cisplatin and taxol would be effective even if single topotecan has failed. Careful evaluation before treatment is indicated.
