NCI Definition: A carcinoma arising in the oral cavity. Most oral cavity carcinomas are squamous cell carcinomas of the tongue, buccal mucosa, or gums. Less frequent morphologic variants include mucoepidermoid carcinoma and adenocarcinoma. [1]

Oral cavity carcinomas most frequently harbor alterations in TP53, CDKN2A, NOTCH1, PIK3CA, and KMT2D [2].

Most Commonly Altered Genes in Oral Cavity Carcinoma

TP53 Mutation, TP53 Missense, TP53 c.217-c.1178 Missense, CDKN2A Mutation, and PIK3CA Mutation are the most common alterations in oral cavity carcinoma [2].
