Abstract

Objectives:

The benefit of radiotherapy (RT) for unresectable hemangioendotheliomas or patients with a high risk of local recurrence is unclear. This single-institution report describes the long-term effectiveness of RT for hemangioendothelioma.

Methods:

From 1976 to 2009, 14 patients with nonmetastatic hemangioendothelioma were treated with RT at our institution. Median patient age was 45 years (range, 20 to 71 y). Nine patients had hemangioendothelioma of the extremities and 5 had spinal tumors. Eleven tumors originated from bone. Most tumors (n=12) were ≤5 cm in diameter. Nine patients had multifocal tumors. Four patients underwent surgery and postoperative RT, whereas 10 had RT alone. All 4 operative patients had microscopic negative margins. Median RT dose was 52.2 Gy (range, 45 to 60 Gy) for RT alone and 62.2 Gy (range, 60 to 64.8 Gy) for postoperative patients. Seven patients received 1.5-2 Gy once daily and 7 patients received 1.2 Gy twice daily. The median follow-up was 10.3 years (range, 0.1 to 28.0 y).

Results:

The 10-year local control, cause-specific survival, and overall survival rates were 100%, 86%, and 73%, respectively. Two patients experienced a distant metastasis and died within 3 months of starting definitive RT. Three patients died of intercurrent illness at a median of 10.5 years after treatment. Nine patients had no evidence of disease at most recent follow-up. No patients experienced greater than grade 1 acute or late toxicity from RT.

Conclusions:

With no local recurrences and minimal risk of toxicity, our data suggest that RT can effectively manage this disease and radical surgery compromising function or cosmesis may be safely avoided with moderate-dose RT.
