Second-look laparotomy in epithelial ovarian carcinoma: precise definition, sensitivity, and specificity of the operative procedure.
Twenty-five women treated with chemotherapy for epithelial ovarian carcinoma underwent "second-look" laparotomy after thorough clinical and radiographic examinations failed to detect residual tumor. Chest roentgenogram, barium enema, upper gastrointestinal series with small-bowel follow through, and abdominopelvic CAT scan were obtained in all patients prior to operation. Inspection, palpation, and multiple biopsies were performed in accordance with precise and detailed protocol requirements. Eight patients (32%) had gross tumor found at laparotomy, while 6 (24%) had no suspicion of residual disease at operation but had cytologic or microscopic evidence of tumor found on review of submitted specimens. Eleven patients (44%) had no gross or microscopic evidence of residual ovarian carcinoma. After follow-up of from 4 to 25 months, 1 of these 11 patients (9%) has suffered a recurrence. The maximum sensitivity of "second-look" laparotomy is 85.7%, and the maximum specificity is 90.9% in this series. Any additional recurrences observed over time will decrease both the sensitivity and specificity of the operation. The sites of microscopic disease support rigid adherence to a precise operative procedure which should minimize the false negative rate.
