Comparison of clinicopathological features and prognosis of gastric cancer located in the lesser and greater curve.

Abstract

Little is known about the features of gastric cancer located in the lesser and greater curve. This study aims to investigate the clinicopathological features and prognosis of gastric cancer located in the lesser and greater curve. From September 2008 to March 2015, 780 gastric cancer patients were enrolled in the present study. The associations between locations and features of patients were analyzed. There were 571 male (73.2%) and 209 female (26.8%) patients. The median age was 56years (ranged 21-86). There were 684 tumors located in the lesser curve (87.7%) and 96 located in the greater curve (12.3%). The incidence of melena was significantly lower in patients with tumors located in the lesser curve than that in the greater curve (8.5 vs 15.6%, P=0.024). The median size of tumors in the lesser curve was significantly larger than that in the greater curve (5.0 (0.3-15) vs 4.0cm (0.5-15), P=0.001). The remaining clinicopathological features were comparable between the two groups (all P>0.05). Tumor location was not a risk factor for the prognosis of gastric cancer by univariate and multivariate analysis (both P>0.05). The postoperative complications (all P>0.05) and prognoses (P=0.279) were comparable between tumors located in the lesser and greater curve. The ratio of gastric cancer located in the lesser to greater curve was 7.1:1. Compared with tumors located in the greater curve, the incidence of melena was significantly lower and the tumor size was significantly larger in tumors located in the lesser curve. The prognoses were comparable between tumors located in the lesser and greater curve.
