Pathological characteristics of colorectal neoplasms according to tumor size and morphological subtypes. Pathological diagnoses of colorectal neoplasms according to the tumor size in each morphological subtype. Frequencies of pT1 carcinomas were compared between depressed and other types in each stratum of the tumor size. Values for P were based on the Wilcoxon rank-sum test for comparisons of rates of pT1 carcinomas between depressed and other subtypes. SSA/P, sessile serrated adenoma/polyp.
