Clinical outcomes and prognostic markers in uterine leiomyosarcoma: a population-based cohort.

Objective: The aim was to identify clinical parameters and immunohistochemical markers predictive of recurrence and overall survival (OS) in a community cohort of patients with primary uterine leiomyosarcoma (ULMS).

Methods/materials: All patients with new diagnosis of ULMS from 1999 to 2007 were identified from the Kaiser Permanente Northern California pathology database. A retrospective chart review was performed to gather demographic and clinical data.
