Primary Angiosarcoma of Bone (original) (raw)

BACKGROUND-Angiosarcoma of bone is a rare high-grade malignant vascular tumor. The literature regarding treatment and outcome of patients with this tumor is limited. We performed a two-institutional retrospective study to analyze treatment and survival of patients with angiosarcoma of bone. PATIENTS AND METHODS-We reviewed patients with the histological diagnosis of primary angiosarcoma of bone treated from 1980 to 2009. Demographic details, histology, treatment and survival were reviewed. RESULTS-38 men, 22 women (median age 54 years). Most lesions occurred in the femur and the pelvis. Metastatic disease at presentation was diagnosed in 24 patients (40%). Forty-three patients underwent surgery, with 30 of them achieving surgical complete remission (SCR). Radiotherapy (RT) was applied to 17 patients, and chemotherapy (CT) to 13/35 and 15/22 patients with localized and metastatic disease, respectively. The 5-year overall survival (OS) was 20%: 33% for patients with localized disease and 0% for metastatic patients. Higher 5-year OS was reported for patients who achieved SCR (46%) than for
