BACKGROUND: Data regarding the role of anthracyclines and taxanes as first‐line treatments of metastatic angiosarcoma are limited. METHODS: Records of 117 metastatic angiosarcoma patients who were treated with either doxorubicin or weekly paclitaxel were reviewed. RESULTS: Seventy‐five patients (64%) were treated with weekly paclitaxel and 42 (36%) with single‐agent doxorubicin. Patients in the weekly paclitaxel group were older and more frequently had angiosarcomas arising from the skin. In the doxorubicin group, 34 patients were evaluable for response: 2 (6%) had complete response, 8 (23.5%) had partial response, 10 (29.5%) had stable disease, and 14 (41%) had progressive disease. In the weekly paclitaxel group, 68 patients were evaluable for response: 9 (13%) had complete response, 27 (40%) had partial response, 20 (29.5%) had stable disease, and 12 (17.5%) had progressive disease. Objective responses to weekly paclitaxel were more frequent in cutaneous angiosarcomas, whereas tumor location did not impact response to doxorubicin. Median progression‐free survival (PFS) was 4.9 months (95% confidence interval [95% CI], 3.9‐6.0 months). Median overall survival (OS) was 8.5 months (95% CI, 6.4‐10.7 months). On multivariate analysis, ECOG performance status (PS) was the sole independent factor associated with PFS and OS. CONCLUSIONS: First‐line single‐agent doxorubicin and weekly paclitaxel seem to have similar efficacy in metastatic angiosarcomas. Cutaneous angiosarcomas respond favorably to weekly paclitaxel. Best supportive care should be considered in patients with poor PS. Cancer 2011. © 2011 American Cancer Society.
