Overview

NCI Definition: An undifferentiated soft tissue sarcoma characterized by the presence of a pleomorphic malignant cellular infiltrate. It is also known as malignant fibrous histiocytoma. [1]

Undifferentiated pleomorphic sarcomas most frequently harbor alterations in TP53, RB1, CDKN2A, ATRX, and CDKN2B [2].

Most Commonly Altered Genes in Undifferentiated Pleomorphic Sarcoma

TP53 Mutation, TP53 c.217-c.1178 Missense, TP53 Missense, CDKN2A Loss, and ATRX Mutation are the most common alterations in undifferentiated pleomorphic sarcoma [2].
