Background:
Radiation-induced angiosarcoma (RA) is a well-recognized complication of breast conservation therapy (BCT).
Methods:
Over a 12-year period, 14 patients with a median age of 68 years were identified retrospectively. The median latency from BCT to onset of RA was 81 months. The incomplete excision rate (complete histologic margin taken to be > 10 mm) was 46%. There was a significant difference in the size of the cutaneous defect between the complete and incomplete excision groups (412 vs 592 cm(2), respectively; P < .05), indicating more extensive disease in the latter group.
Results:
The tumor recurred locally in 12 patients (92%). The median time to local recurrence (LR) in patients with incomplete excision was 3 versus 23 months in patients who had a complete excision. The median survival time for patients who underwent complete versus incomplete excision was 42 and 6 months, respectively.
Conclusions:
RA is a challenging condition, with a prolonged latency period and variable clinical progression. Incomplete excision of RA is a surrogate marker of aggressive disease and is associated with rapid LR and poor survival.
