aTNM classification. Tumor depth of invasion was defined as follows: T1, tumor invades submucosa; T2, tumor invades muscularis propria; T3, tumor invades through the muscularis propria into pericolorectal tissues; T4, tumor penetrates to the surface of the visceral peritoneum or tumor directly invades or is adherent to other organs or structures. Values are expressed as the median (range) or n (%). PS, performance status; C, cecum; A, ascending colon; T, transverse colon; D, descending colon; S, sigmoid colon; Ra, upper rectum; Rb, lower rectum; Pap, papillary adenocarcinoma; Wel, well-differentiated adenocarcinoma; Mod, moderately differentiated adenocarcinoma.
