NCI Definition: A usually aggressive malignant neoplasm arising from the uterine corpus and less often the cervix. It is characterized by the presence of two components: a malignant epithelial component and a sarcomatous component. In the uterine corpus the epithelial component is usually glandular whereas in the cervix is usually non-glandular. Carcinosarcoma of the cervix, although it is aggressive, it may have a better prognosis compared to the uterine corpus carcinosarcoma. [1]

Uterine carcinosarcomas most frequently harbor alterations in TP53, PIK3CA, KRAS, FBXW7, and CCNE1 [2].

Most Commonly Altered Genes in Uterine Carcinosarcoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, PIK3CA Mutation, and TP53 Exon 7 Mutation are the most common alterations in uterine carcinosarcoma [2].
