Abstract

In this study, our aim was to determine the possible effects of Helicobacter pylori (HP), chronic atrophic gastritis (CAG), and gastrointestinal metaplasia (GIM) on survival in operated bowel type gastric cancer patients (INT-GC). Among 548 patients, 347(63.3%) were male. The median age was 57 years. Disease-free survival (DFS) and overall survival (OS) were significantly shorter in patients with GIM than those in patients without GIM (log rank, P = 0.003 and log rank P = 0.003, respectively). Multivariate analysis showed that presence of GIM (HR, 2.1) was found to be an independent factor of worse DFS. In our study, stage pIII patients with GIM had significantly shorter DFS and OS than those without GIM (log rank p = 0.008 and log rank p = 0.001, respectively). However, in subgroup analysis of patients with GIM, there was no significant DFS and OS difference between patients with stage pI and pII disease (log rank p = 0.999, log rank p = 0.184 vs. log rank p = 0.409, log rank p = 0.281, respectively).
