title: [Comparison of clinicopathological features and operative prognosis of gastric carcinoma complicated with Krukenberg tumor and with pelvic peritoneal dissemination].
abstract: OBJECTIVE
  To compare the clinicopathological characters and operative prognosis of gastric cancer complicated with Krukenberg tumor and with pelvic peritoneal dissemination.
  
  
  METHODS
  Thirty-nine female cases of gastric carcinoma with pelvic metastasis were treated operated on between August 1994 and March 2006. Among them, 18 cases were complicated with Krukenberg tumor and 21 cases with pelvic peritoneal dissemination. The clinicopathological characters in the two groups were recorded and compared and the operative prognosis were analyzed.
  
  
  RESULTS
  There was no significant difference in age, tumor location and size, hepatic metastasis, organic encroachment, infiltration degree, positive lymph nodes, differentiated degree, tissue typing, Borrmann typing, value of carcinoembryonic antigen between the two groups (P > 0.05). The rate of P3 (peritoneal dissemination) in the cases of Krukenberg tumor (44.4%) was significantly lower than that in pelvic peritoneal dissemination group (85.7%) (P < 0.01), whereas the focal resection rate (77.8%) and multi-organ dissection rate (55.6%) were significantly higher than in pelvic peritoneal dissemination (38.0%, 23.8%) (P < 0.05). The mean survival of all cases was 12.6 months. The mean survival in the patients with Krukenberg tumor and pelvic peritoneal dissemination was 20.5, 15.0 months, respectively (P < 0.05). The mean survival of total focal resection, palliative focal resection, non-focal resection was 19.9, 12.5 and 5.7 months, respectively (P < 0.01). Non-focal resection, pelvic peritoneal dissemination, P3 of peritoneal implantation, hepatic metastasis, organic encroachment, total gastric cancer were unfavorable prognosis factors for all cases.
  
  
  CONCLUSIONS
  Compared with pelvic peritoneal dissemination, the gastric cancer with Krukenberg tumor is associated with more limited peritoneal dissemination, higher resection rate and better prognosis. Focal resection can improve the prognosis.
