Clinicopathological characristics of mucinous gastric carcinoma / 中国普通外科杂志

ABSTRACT

ObjectiveTo investigate the clinicopathological characristics of mucinous gastric carcinoma (MUC). MethodsFrom 1994 to 2001, 438 gastric cancer patients underwent operation, among them, 36 patients (8 2%) were with MUC. The clinicopathological parameters and prognosis of MUC and non MUC were analyzed retrospectively. ResultsThere were no significant differences in age, sex, tumor site and hepatic metastasis. Patients with MUC had higher rate of serosal invasion, invasive type lymph node involvement, peritoneal dissemination. Patients with MUC were of more advanced stage (stage Ⅲ and Ⅳ:MUC 88 9%,non MUC 73 9%). The 1 year and 2 year survival rate for MUC patients was lower than that for non MUC patients (50 5%?33 1% vs. 74 9%?64 7%). Conclusions The poor prognosis of MUC was correlated with frequent serosal invasion, lymph node involvement, peritoneal dissemination, and advanced stage at the time of diagnosis.
