Clinicopathological analysis of synchronous liver metastasis in gastric cancer and evaluation of surgical outcomes / 中华胃肠外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the clinicopathological factors affecting synchronous liver metastasis in gastric cancer,and evaluate its surgical outcome.</p><p><b>METHODS</b>Clinical data of 44 patients with synchronous hepatic metastasis from gastric cancer from Aug. 1994 to Feb. 2004 were reviewed retrospectively, and compared with those of 576 gastric cancer patients without hepatic metastasis to analyze the clinicopathological factors affecting synchronous liver metastasis from gastric cancer. The survivals after radical resection, palliative and exploratory operation were compared.</p><p><b>RESULTS</b>Univariate analysis revealed that ascites, pelvic and peritoneal seeding, serosal invasion, lymph node metastasis, involvement of neighboring organs, Borrmann types,depth of infiltration were correlated with synchronous hepatic metastasis from gastric cancer (P< 0.01). Logistic regression showed peritoneal seeding (P=0.003, OR=1.629), serosal infiltration (P=0.000, OR=3.000), lymph node metastasis (P=0.081, OR=1.689) were independent risk factors for synchronous hepatic metastasis from gastric cancer. Sixteen (36.4%) patients received radical excision, 15 (34.1%) patients palliative operation, and 13 (29.5 %) patients exploratory operation,and the median survival times were 19.5, 11.0 and 6.2 months respectively (P< 0.05).</p><p><b>CONCLUSIONS</b>Peritoneal seeding,serosal infiltration, lymph node metastasis are most important risk factors for synchronous hepatic metastasis from gastric cancer. Radical resection of gastric primary lesion and hepatic metastases can significantly prolong survival time.</p>
