This study found that nearly one-third of early ovarian cancer patients required rectosigmoid colon resection for complete tumor removal, often due to cancer invasion, endometriosis, or adhesions.

Abstract

Objective To investigate the surgical effort of endometriosis the in the surgical management of early ovarian cancer. Design: A retrospective study Setting National Cancer Center Population All women who underwent cytoreductive surgery between January 2001 and July 2008 Method: Retrospective medical chart review Main Outcomes Measure Requirement of the rectosigmoid colon and pathological outcome of resected the rectosigmoid colon Results: Of the 37 stage I and 15 stage II ovarian cancer women, twelve cases (23.1%) were serous carcinomas and 40 (76.9%) were non-serous carcinomas (9 mucinous, 11 endometrioid, 14 clear cell, 2 transitional cell, and 4 mixed carcinomas). Co-existence of endometriosis was identified in 28.8% of the patients at adnexa, pelvic peritoneum, and rectum. Resection of the rectosigmoid colon to completely resect all suspicious lesions was required in 15 patients (28.8%). Cancer and endometriosis were identified in 6 (40%) and 5 (33%) patients, respectively. Fibrosis and/or adhesion were identified in 4 (27%) patients. Complications related resection of the rectosigmoid colon such as fistula or leakage were not identified with a median follow up of 50 months. Conclusions: Resection of the rectosigmoid colon with adjacent pelvic peritonectomy is required in approximately one-third of the patients with early ovarian cancer for complete removal of all suspicious metastatic lesions in the pelvis. Cancer invasion, endometriosis, and fibrosis and/or adhesion are the causes to perform resection of the rectosigmoid colon in such patients.
