ABSTRACT
PURPOSE: Borrmann type IV gastric cancer is still detected at an advanced stage and survival rates for these patients remain poor. The purpose of this study was to provide valuable prognostic and surgical information on patients with Borrmann type IV gastric cancer. METHODS: We compared the clinicopathological features of Borrmann type IV gastric cancer with those of other types of gastric cancer. Clinicopathologic features of patients with Borrmann type IV gastric cancer were evaluated as prognostic predictors by univariate and multivariate analyses. RESULTS: The results showed that Borrmann type IV gastric cancer had more advanced and unfavorable clinicopathological factors compared with other Borrman types. The 5-year overall survival rate was 16.7%, and the median survival 25 months. The 5-year overall survival rate was influenced by tumor size, depth of invasion, lymph node metastasis, and chemotherapy. Of these, independent prognostic factors were lymph node metastasis (present vs absent, risk ratio 1.855, p=0.002) and radical (R0) resection (no vs yes, risk ratio 2.035, p<0.001). A significant survival benefit for radical resection was observed, with a 5-year overall survival rate of 30.7% compared with non-radically resected cases (4.8%). CONCLUSIONS: Early detection and radical resection were essential to improve the prognosis of patients with Borrmann type IV gastric cancer.
