A closer look at the natural history and recurrence patterns of high-grade truncal/extremity leiomyosarcomas: A multi-institutional analysis from the US Sarcoma Collaborative

Natural history and outcomes for truncal/extremity (TE) soft tissue sarcoma (STS) is derived primarily from studies investigating all histiotypes as one homogenous cohort. We aimed to define the recurrence rate (RR), recurrence patterns, and response to radiation of TE leiomyosarcomas (LMS). Patients from the US Sarcoma Collaborative database with primary, high-grade TE STS were identified. Patients were grouped into LMS or other histology...
