Failure of second-look laparotomy to influence survival in epithelial ovarian cancer.

The survival benefit of second-look laparotomy after completion of primary chemotherapy in patients with epithelial ovarian cancer has been assessed in a prospective randomised trial of 166 patients. Patients were randomised into three groups. All were initially treated with cisplatin (100 mg/m2 x 5) after primary laparotomy. Group A (n = 53) was scheduled to have a second-look laparotomy, followed by cyclical oral chlorambucil. Group B (n = 56) was scheduled to have a second-look laparotomy, followed by total abdominal and pelvic irradiation, and group C (n = 57) received oral chlorambucil as for group A but had no second-look operation. With a median follow up of 46 months (range 21-64), no differences in survival were noted between the three groups. The median survival for group A was 21 months (95% CI 11-31 months), for group B 15 months (11-19), and for group C 17 months (8-26). Thus second-look laparotomy after completion of first-line single-agent cisplatin chemotherapy did not confer any survival benefit on patients with epithelial ovarian cancer.
