The Complex Management of the Breast Angiosarcoma: A Retrospective Study

Area of Science:

• Oncology
• Surgical Pathology
• Medical Oncology

Background:

• Breast angiosarcoma is a rare, aggressive malignancy with poor prognosis.
• Two distinct subtypes exist: primary breast angiosarcoma (PBA) and secondary breast angiosarcoma (SBA).

Purpose of the Study:

• To compare institute experience with literature data on PBA and SBA.
• To analyze treatment patterns and outcomes for breast angiosarcoma subtypes.

Main Methods:

• Retrospective analysis of 29 patients diagnosed with PBA or SBA between 2006 and 2019.
• Evaluation of surgical, neoadjuvant, and adjuvant treatment modalities.
• Comparison of recurrence-free survival (RFS) and overall survival (OS) between subtypes.

Main Results:

• Surgery was the primary treatment for all patients; only 6 received adjuvant therapy.
• Taxanes with or without gemcitabine, and anthracyclines were preferred chemotherapy regimens.
• PBA patients presented at a younger median age (38 vs. 75) and showed a trend towards lower RFS and OS compared to SBA patients, though not statistically significant.

Conclusions:

• Primary breast angiosarcoma is associated with a younger age at diagnosis compared to secondary breast angiosarcoma.
• Lower median RFS and OS were observed in PBA patients versus SBA patients.
• Findings highlight differences in presentation and suggest potential variations in disease behavior between breast angiosarcoma subtypes.
