Overview

NCI Definition: A rare tumor containing unequivocal elements of both hepatocellular and cholangiocarcinoma that are intimately admixed. This tumor should be distinguished from separate hepatocellular carcinoma and cholangiocarcinoma arising in the same liver. The prognosis of this tumor is poor. [1]

Combined hepatocellular carcinoma and cholangiocarcinomas most frequently harbor alterations in TP53, PBRM1, CDKN2B, CDKN2A, and BAP1 [2].

Most Commonly Altered Genes in Combined Hepatocellular Carcinoma and Cholangiocarcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, CDKN2B Loss, and CDKN2A Loss are the most common alterations in combined hepatocellular carcinoma and cholangiocarcinoma [2].
