NCI Definition: A malignant neoplasm that arises from the epithelium of any part of the digestive system. Representative examples include colorectal carcinoma, esophageal carcinoma, and pancreatic carcinoma. [1]

Digestive system carcinomas most frequently harbor alterations in TP53, KRAS, CDKN2A, ARID1A, and ERBB2 [2].

Most Commonly Altered Genes in Digestive System Carcinoma

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