Clinicopathological correlations with p53 expression in gastric cancer patients with curative resection

Purpose: Mutations in the p53 gene and accumulation of p53 protein are the most common genetic events in gastric carcinomas. This study evaluates the association of p53 gene expression with clinicopathologic findings and prognosis of gastric cancer patients who underwent curative resection. Methods: Retrospective analysis was performed on 236 consecutive patients with gastric cancer who underwent surgery at the Kosin University Gospel Hospital between December 2011 and September 2012. Nuclear p53 expression was detected by immunohistochemistry. Results: p53 expression was detected in 213 patients (90.3%). There was no significant association between positivity for p53 and clinicopathological features. Expression of p53 (P
