NCI Definition: A malignant epithelial neoplasm that arises from the rectum and invades through the muscularis mucosa into the submucosa. The vast majority are adenocarcinomas. [1]

Rectal carcinomas most frequently harbor alterations in APC, TP53, KRAS, SMAD4, and FBXW7 [2].

Most Commonly Altered Genes in Rectal Carcinoma

APC Mutation, TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, and KRAS Mutation are the most common alterations in rectal carcinoma [2].
