Abstract

OBJECTIVE
To evaluate the efficacy and side effects of cispaltin and carboplatin each in combination with paclitaxel in recurrent epithelial ovarian cancer who had not taken paclitaxel-based chemotherapy.
MATERIALS AND METHODS
Between January 1994 and October 1999, in department of obstetrics and gynecology, Asan medical Center, 42 recurrent ovarian cancer patients who had initial platinum-based chemotherapy except paclitaxel were treated with paclitaxel-based chemotherapy. One group was 14 patients treated with paclitaxel-cisplatin and the other group was 28 patients treated with paclitaxel-carboplatin. Disease free interval before recurrence was 6 months at least. Patients received paclitaxel 135mg/m2 followed by either cisplatin 75mg/m2 or carboplatin 300mg/m2. The schedule was repeated every 3 weeks for at least 6 cycle. Response was evaluated by physical examination, serial serum CA 125 measurement, chest PA before each cycle, and abdomino-pelvic CT scan every 3 cycles.
RESULTS
As paclitaxel-cisplaitin group, with a median follow-up of 34.5 months (range, 9-60 months), 1 patient had complete response, 6 patients had partial response, 3 patients had stable disease and 4 patients had persistent disease, overall response rate was 50%, mean survival duration was 40 months. As paclitaxel-carboplatin group, with a median follow-up of 25.5 months (7-36 months), 4 patients had complete response, 11 patients had partial response, 6 patients had stable disease, and 7 patients had persistent disease, overall response rate was 53.4%, mean survival of 24 months. As grade of side effects in each group, we evaluated leukopenia, anemia, thrombocytopenia, nausea, vomiting, fever, neurological abnormality, and renal abnormality. The rate of grade 3 to 4 leukopenia was 11% in paclitaxel-cisplatin arm and 17% paclitaxel-arboplatin, in arm.
CONCLUSION
These results demonstrate that the combined chemotherapy of paclitaxel followed by cisplatin or carboplatin is highly effective and safe in recurrent epithelial ovarian cancer who had taken no previous paclitaxel-based chemotherapy.
