Rational Operation for Primary Gastric Carcinoma with Liver Metastasis

OBJECTIVE To investigate the prognosis of advanced gastric carcinoma patients with liver metastasis, and provide a foundation for rational operations. METHODS The operations and prognosis of 102 primary gastric carcinoma patients with liver metastasis were studied retrospectively. RESULTS In gastric carcinoma patients with H1 metastasis who underwent a resection operation, the 6-month, 1- and 2-year post-operative survival rates were 61%, 42% and 7%. There was a statistically significant difference in survival between resected and non-resected patients （P=0.000） in gastric carcinoma cases with H2 metastasis, resection operations resulted in 54%, 16% and 8% respective survival rates, with no significant difference compared to patients not receiving a resection （P=0.132）. Gastric carcinoma patients with H3 metastasis who received a resection operation showed 25%, 13% and 0% respective survivals with no significantly better prognosis compared to the non-resected cases （P=0.135）. There was no statistically significant difference in survival between the cases with or without peritoneal metastasis （P=0.152）. CONCLUSION A resection operation provides a better prognosis for gastric carcinoma patients with H1 metastasis independent of peritoneal metastasis, but resection has no benefit for gastric carcinoma cases with H2 or H3 metastasis. Peritoneal metastases are not the significant influencing factor for the prognosis of gastric cancer with liver metastasis.
