title: Prognostic factors for and prognostic value of mesenteric lymph node involvement in advanced-stage ovarian cancer.
abstract: OBJECTIVE
  To determine the prognosis of and prognostic factors for mesenteric node involvement in patients undergoing a bowel resection at the time of debulking surgery for primary treatment of advanced-stage ovarian cancer (ASOC).
  
  
  METHODS
  A retrospective review of patients treated between 2005 and 2008 for ASOC and undergoing initial and interval debulking surgery with bowel resection (whatever the bowel segment). The characteristics and prognostic impact of mesenteric node involvement were studied.
  
  
  RESULTS
  During the study period, 52 patients underwent debulking surgery for ASOC with bowel resection. Eighteen and 34 patients underwent initial or interval debulking surgery respectively. The most frequent site of the bowel resection was the rectosigmoid colon (38 patients; 73%) and 12 patients had resection of at least 2 intestinal segments. All patients had a complete macroscopic resection of peritoneal disease. Nineteen patients (37%) had mesenteric node involvement with a median of 4 involved nodes (range, 1-12). The degree of involvement of the intestinal wall and retroperitoneal node involvement (pelvic or para-aortic) had no impact on the risk of mesenteric node involvement. Overall survival and the location of recurrent disease were similar in patients with or without spread to mesenteric nodes.
  
  
  CONCLUSIONS
  This study suggests that mesenteric node involvement is frequent in patients undergoing bowel resection in ASOC. Such spread does not appear to have an impact on patient survival. Modifying peroperative (particularly the extent of the mesocolon resection) or postoperative management is therefore unnecessary.
