Resumo: | Abstract Objective: To characterize a population of patients with radiation-induced angiosarcoma (RIAS) of the breast treated at an oncology center, focusing mainly on the imaging features, although also on the clinical presentation, diagnosis, and management. Materials and Methods: We performed a retrospective review of patients with histologically proven angiosarcoma of the breast or chest wall, all of whom received radiotherapy, after conservative or radical breast surgery, between 2000 and 2015. Results: Eleven patients met the inclusion criteria. The median age at the time of diagnosis of RIAS of the breast was 71.5 years (range, 58-87 years), and the median latency period was 8.9 years (range, 4-27 years). The rate of local recurrence was 54.4%, RIAS recurring after a median period of 10 months (range, 3-18 months), and distant metastases occurred in three patients (27.3%). All of the tumors were accompanied by skin changes, and a palpable mass was seen in four. Most of the imaging findings were nonspecific. Six patients underwent magnetic resonance imaging, which revealed pronounced skin enhancement in all six. Ultrasound-guided core needle biopsies were negative in three of the eight patients. Conclusion: RIAS of the breast is a rare but recognized complication of radiotherapy for breast carcinoma, with a poor prognosis and high recurrence rate, which requires a high index of suspicion for a prompt diagnosis. |
