BACKGROUND: There are no data about the natural history of leiomyosarcoma of vascular origin (vLMS) in comparison with leiomyosarcoma (LMS) of other origin and about the management of advanced disease.
METHODS: Among 1472 patients diagnosed with sarcoma from January 1980 to December 2008 at our institution, 195 patients (13%) had LMS. LMS had a vascular origin in 14 cases (7%).
RESULTS: Patients with vLMS had a significantly worse median metastasis-free survival (MFS) (0.25 versus 9.6 years, P = 0.001) and overall survival (OS; 2.1 versus 7 years, P < 0.0001) than patients with LMS of other origin. On multivariate analysis, grade and vascular origin were the sole independent adverse prognostic factors for OS. Eight metastatic patients with vLMS received a first-line anthracycline chemotherapy regimen. Two patients had partial response, four had stable disease and two had progressive disease. OS of patients with metastatic vLMS was not significantly different from that observed in patients with metastatic LMS of other origin (22.1 versus 16.5 months, P = 0.84).
CONCLUSIONS: Vascular origin is an independent adverse prognostic factor for MFS and OS in patients with LMS. Patients with metastatic vLMS had a similar outcome than patients with metastatic LMS of other origin.
