Multimodal approach (surgery, chemotherapy, and radiotherapy) in the treatment of advanced ovarian carcinoma

Abstract

Forty-five patients with advanced ovarian carcinoma without prior chemotherapy were treated with cisplatin-Adriamycin (doxorubicin) combination, 50 mg/m2 intravenously, for 11 cycles. Second-look operation (SLO) was performed in patients without evidence of disease at the end of chemotherapy. Abdominopelvic irradiation was administered to those found to have microscopic or minimal disease (tumor less than 2 cm) at SLO. Forty patients were evaluable. Chemotherapy induced complete response in 56.7% and partial response in 16.7%. In 25% of the reoperated patients, no tumor was found; 30% had microscopic disease; 25% had minimal disease; and 20% had larger tumors. Two-year survival rate was 45%. The residual tumor left at initial operation, the histologic grade, and the response to chemotherapy influenced survival. Toxicity was moderate. There were three treatment-related deaths (one due to sepsis, one due to cardiotoxicity, and one at SLO, respectively). Radiotherapy was poorly tolerated after chemotherapy. The median duration of follow-up was 21.5 months. Further follow-up is needed to study the long-term benefits of this multimodal approach.
