Abstract

Variables associated with a negative second-look laparotomy in patients with stage III epithelial ovarian carcinoma are analyzed. Fifty-six patients were clinically free of disease after systemic chemotherapy and were subjected to second-look laparotomy to assess tumor status. Eighteen of these patients (32.1%) had no evidence of malignancy. Eight (14.3%) additional patients with no gross evidence of disease at laparotomy had microscopic persistence; five of these had disease documented in the pelvic or para-aortic lymph nodes. Significant variables associated with a histologically and cytologically negative second-look operation were low tumor grade (P less than .01), the use of cis-platinum containing combination chemotherapy (P less than .01), patient age less than or equal to 50 years (P less than .02), small residual tumor (less than 0.5 cm) before chemotherapy (P less than .05), and metastatic tumor less than or equal to 10 cm before initial cytoreduction (P less than .05). Patients treated with six to nine cycles of combination chemotherapy had the same probability of a negative second-look laparotomy as those treated with ten to 12 cycles. Multivariate discriminate analysis indicated that patients with low tumor grade, those receiving cis-platinum containing combination chemotherapy, and those with minimal residual tumors (less than 0.5 cm) after primary cytoreductive surgery correctly classify second-look status in 78.6% of patients. Until a nonsurgical method of monitoring subclinical disease is available, a through second-look laparotomy, including a pelvic and para-aortic lymphadenectomy, should be performed.
