BACKGROUND: Angiosarcomas (AS) are rare, aggressive tumors. Optimal treatment has not been well defined. The authors undertook a retrospective review of patients seen at their institution with the intent of identifying prognostic factors and optimal treatment strategies. METHODS: Between 1955 and 1990, 67 patients with AS were seen at the University of California, at Los Angeles Medical Center. Follow-up ranged from 1 to 173 months with a median of 30 months. RESULTS: The overall prognosis was poor. The actuarial 2- and 5-year disease free survivals (DFS) were 44% and 24%, respectively. Of 52 recurrences after primary treatment, 81% (42 of 52) had a component of local failure. Twenty-eight patients had developed distant metastases at last follow-up. Of patients who received surgery (S) and radiation therapy (RT), with or without chemotherapy (CT), 5-year actuarial DFS was 43%, compared with 17% for patients who underwent S +/- CT as initial treatment (P = 0.03). Only 9% of patients (1 of 11) treated with RT +/- CT were rendered free of disease. CONCLUSIONS: Patients with AS usually present with high grade histology, and with multifocal disease. There is a propensity for both local recurrence and distant metastases. Our results and a review of the literature, suggest that S plus RT offers the best chance for long term control of this aggressive tumor. The role of CT remains undefined.
