^aP < 0.05,

^bP < 0.01, From comparison in each group of clinicopatho-logic feature by chi-square test or Fisher’s exact test. m: mucosa, sm: submucosa, mp: muscularis propria, ss: subserosa, se: inva-sion to serosa, si: invasion to other organ. Tumor size was de-fined as the largest size in extension on the gastric mucosa.
