Surgical implications of mesenteric lymph node metastasis from advanced ovarian cancer after bowel resection

Authors


Abstract

Background

Studies addressing mesenteric and mesocolic lymph node metastasis in patients with advanced ovarian cancer that have undergone bowel resection are lacking.

Methods

A retrospective analysis was performed in a series of 50 individuals who underwent surgical cytoreduction for epithelial ovarian cancer that included bowel resection from April 2004 to September 2010.

Results

Forty-one patients had bowel resection with mesenteric lymph nodes that were suitable for analysis. Twenty-four (58.5%) patients underwent retosigmoidectomies, 14 (34.1%) received other types of colectomies, and three (7.3%) underwent small bowel resection. There was serosal involvement in 14 cases (34.1%), muscularis propria invasion in 13 cases (31.7%), submucosa invasion in six cases (14.6%), and mucosa in eight cases (19.5%). Lymphatic invasion was observed in 24 patients (58.5%). A median of 14 mesenteric lymph nodes were analyzed. Metastatic lymph nodes were observed in 29 (70.7%) cases. Invasion into the muscularis propria (P = 0.036), lymphatic invasion (P = 0.045), and retroperitoneal lymph node metastasis (P = 0.002) correlated significantly with mesenteric lymph node involvement.

Conclusions

Resection of regional lymph nodes of affected organs that is similar to surgical procedures that are performed for colorectal carcinoma is an appropriate, optimal debulking surgery for patients with ovarian carcinoma. J. Surg. Oncol. 2011; 104:250–254. © 2011 Wiley-Liss, Inc.
