Results of resection of gastric cancer with distant metastases

BACKGROUND/AIMS: The present study was carried out in order to examine the outcome of resection in cases of gastric cancer with distant metastases. METHODOLOGY: The survival rates of two hundred and eighty-one patients who had undergone resection for primary carcinomas of the stomach, and who had distant metastases according to the TNM classification, were studied. RESULTS: The 5-year survival rates for patients with metastasis to the peritoneum or group 3 nodes were 8.9% and 15.3% respectively and were significantly higher than the survival rates for patients with metastasis to the liver (0%), to group 4 nodes (2.2%) or to more than one site among the liver, lymph nodes and peritoneum (3.5%). Moreover, the 5-year survival rates for patients with metastasis to the peritoneum and N3 nodes increased significantly to 29.4% and 24.2%, respectively, when curative surgery was performed. CONCLUSIONS: The findings of the present study suggests that metastases to the adjacent peritoneum or group 3 nodes have a greater chance of being cured using radical surgery, and that gastrectomy with extended lymphadenectomy (D2-D3) may be used for advanced gastric cancer if there is no gross evidence of metastasis to the distant peritoneum, liver or group 4 nodes.
