Overview

NCI Definition: A rare, high grade sarcoma that arises from the endometrial stroma. It is characterized by round cell morphology. It was previously also known as undifferentiated uterine sarcoma. In 2014, high grade endometrial stromal sarcoma was reclassified and is currently considered a distinct and rare neoplasm. It appears to have a prognosis that falls between low grade endometrial stromal sarcoma and undifferentiated sarcoma. [1]

High-grade endometrial stromal sarcomas most frequently harbor alterations in ZRSR2, CDKN2A, YWHAE, PTEN, and PBRM1 [2].

CDKN2A Loss, ZRSR2 Loss, YWHAE-NUTM2B Fusion, PBRM1 Mutation, and NUTM2B-YWHAE Fusion are the most common alterations in high-grade endometrial stromal sarcoma [2].
