NCI Definition: An aggressive malignant smooth muscle neoplasm, arising from the uterine corpus. It is characterized by a proliferation of neoplastic spindle cells. [1]

Uterine corpus leiomyosarcomas most frequently harbor alterations in TP53, RB1, ATRX, MED12, and PTEN [2].

Most Commonly Altered Genes in Uterine Corpus Leiomyosarcoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, RB1 Loss, and ATRX Mutation are the most common alterations in uterine corpus leiomyosarcoma [2].
