NCI Definition: A malignant epithelial neoplasm characterized by the presence of spindle cells and anaplastic morphologic features. Giant cells and a sarcomatous component may also be present. [1]

Sarcomatoid carcinomas most frequently harbor alterations in TP53, KRAS, CDKN2A, MET, and CDKN2B [2].

Most Commonly Altered Genes in Sarcomatoid Carcinoma

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