Second-look laparotomy in stage I ovarian cancer following comprehensive surgical staging.

Abstract

To evaluate the role of second-look laparotomy in patients with comprehensively staged stage I epithelial ovarian cancer. We reviewed the medical records and obtained long-term follow-up on 54 stage I patients who had second-look laparotomies following complete surgical staging and chemotherapy. The distribution by stage was as follows: stage IA 18 (33%), stage IB two (4%), and stage IC 34 (63%). Eighteen patients (33%) had endometrioid tumors, 12 (22%) clear cell, 13 (24%) mucinous, eight (15%) serous, and three (6%) undifferentiated. Forty-four patients (82%) had grade 2 or 3 tumors. Thirty-eight (70%) were treated with platinum-based regimens and 16 (30%) received non-platinum regimens. At second-look laparotomy, tumor was identified in three women (5.5%). Stage, cell type, and grade did not predict the second-look laparotomy result, although no patient with a grade 1 tumor had a positive second-look laparotomy. With a mean follow-up of 48 months from second-look laparotomy, 11 women (22%) have had recurrences following negative second looks. Tumor grade was a strong predictor of recurrence following negative second-look laparotomy (P < .0001), with the risk of recurrence being 0% for grades 1 and 2 and 52% for grade 3. Substage, cell type, and chemotherapy type and duration did not predict recurrence. The likelihood of a positive second-look laparotomy is about 5% in well-staged stage I ovarian cancer. Patients with stage I, grade 3 tumors have a risk of recurrence of approximately 50% following negative second-look laparotomy.
