Abstract

Objective: To profile the incidence of mesenteric lymph node metastases in patients with ovarian carcinoma and metastases to the gastrointestinal tract in order to determine the optimal technique for surgical debulking. Methods: The slides and charts of all patients with ovarian carcinoma who had undergone bowel resection were retrospectively reviewed and follow-up information was obtained. Results: Of 100 separate bowel resections 44% had penetration of metastases to the muscularis, 18% had invasion through the submucosa, 4% had mucosal perforation, and two patients had clinical perforation. Fifty-five percent of all resections demonstrated lymph–vascular space invasion (LVSI). In the 33 specimens which included pathologic analysis of mesenteric lymph nodes, 79% had positive LVSI, which correlated with the presence of mesenteric lymph node metastases (P= 0.05) but not histologic grade (P= 0.20). When surgery was performed for secondary debulking, the frequency of mesenteric node metastasis was higher (P= 0.15). There was a trend for patients with positive mesenteric nodes to fail sooner (median survival, 20 months vs 32 months). Conclusions: Because ovarian carcinoma metastases to the gastrointestinal tract are frequently associated with metastases to mesenteric lymph nodes, gynecologic oncology surgeons may wish to consider resection of the mesentery in a wedge fashion similar to current standards of resection for primary bowel carcinoma in cases in which a bowel resection is being performed with the intent to debulk to zero visible residual disease.

    However, the mechanism behind the haematogenous PLM formation is not well explored. It is not surprising that OC, invading the bowel from the serosal surface, easily conquer the lymph-vascular channels and venous streams highly concentrated in the subserosal space [6]. Naxerova et al. [20] conducted a study on the mutation patterns between primary tumours, lymph nodes and distant metastases in CRC with the aim to discriminate the possible relationship between these entities.

    Among the 24 resections with involved lymph nodes at the pathological analysis, 81% percent of cases with positive mesenteric nodes had lymphovascular space involvement (LVSI).15 Patients with such spread tend to fail sooner (median survival duration of 20 months versus 32 months in patients without involved mesenteric lymph nodes).15 At the end of their publication, the authors suggested that surgical resection of the mesentery should be similar to that performed in patients with primary bowel carcinoma in order to debulk residual metastatic nodes “remaining” in the unresected meso to zero visible residual disease.15

    Thus, establishing an adequate pre-operative and/or intraoperative work-up is of the upmost importance in identifying which ovarian cancer patients will require colorectal surgery. Regarding mesocolic lymphnode status, in contrast to data reported in other literature,37 we did not observe any significant difference in oncologic outcome between patients with positive and negative mesorectal lymphnodes. However, since mesocolic lymphnode are often involved, we believe that, in the context of AOC complete cytoreduction, debulking procedures should include a sigmoid mesocolectomy with resection of the associated lymphatic tributaries at the time of RR, as performed for intestinal carcinoma.
