New Haven, Conn. In a new study, Yale Cancer Center researchers have defined the genetic landscape of uterine leiomyosarcomas (uLMS). Furthermore, using fully sequenced patient-derived xenografts, the team has preclinically validated new treatment modalities, which may point to new treatments for uterine cancer. Study results were published online in an early edition of the
Proceedings of the National Academy of Science (PNAS).
Uterine cancer is the most common gynecologic malignancy and uterine leiomyosarcomas (uLMS) are highly lethal sarcomas arising from the myometrium, the smooth muscle layer of the uterus. They represent the most common type of uterine sarcomas, which overall account for three to seven percent of all uterine cancers. uLMS have poor prognosis and are characterized by aggressive biological behavior leading to early local and distant metastatic spread.
