Associated Genetic Biomarkers


NCI Definition: An adenocarcinoma arising from the gallbladder. It is the most common malignant tumor of the gallbladder and it is usually well to moderately differentiated. The incidence is higher in patients with gallstones than in patients without gallstones. Signs and symptoms usually present late in the course of the disease and are reminiscent of those of chronic cholecystitis including right upper quadrant pain. Histologic variants include adenocarcinoma of the intestinal type, clear cell adenocarcinoma, mucinous adenocarcinoma, papillary adenocarcinoma, and signet ring adenocarcinoma. [1]

Gallbladder adenocarcinomas most frequently harbor alterations in TP53, CDKN2A, SMAD4, ERBB2, and ARID1A [2].

Most Commonly Altered Genes in Gallbladder Adenocarcinoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, TP53 Exon 7 Mutation, and TP53 Exon 8 Mutation are the most common alterations in gallbladder adenocarcinoma [2].
