Breast Angiosarcoma: 15-Years Experience

Area of Science:

• Oncology
• Surgical Oncology
• Cancer Research

Background:

• Breast angiosarcoma is a rare and aggressive cancer, occurring as primary (PAS) or secondary (SAS) types.
• Secondary angiosarcoma often arises after radiation therapy for breast cancer.
• This study focuses on the management and outcomes of breast angiosarcoma within a specialized breast and surgical oncology unit.

Purpose of the Study:

• To evaluate the clinical characteristics, management strategies, and survival outcomes of patients with primary and secondary breast angiosarcoma.
• To compare outcomes between primary and secondary breast angiosarcoma.
• To highlight the diagnostic challenges and emphasize the need for early detection and specialized care.

Main Methods:

• Retrospective review of patients with histologically confirmed breast angiosarcoma (PAS or SAS) treated between 2009 and 2024.
• Analysis of patient demographics, clinical presentation, treatment modalities (surgery, radiotherapy, chemotherapy), complications, and survival data.
• Comparison of outcomes between PAS and SAS groups.

Main Results:

• Fifteen patients were analyzed: 4 with PAS and 11 with SAS.
• SAS patients were older and had a history of prior breast cancer radiotherapy; they often presented with skin discoloration.
• While management (surgical resection) was similar, local recurrence rates were 9.1% for SAS and 0% for PAS. Mortality rates were 25% for PAS and 18.2% for SAS.

Conclusions:

• Breast angiosarcoma has a poor prognosis, characterized by high recurrence and mortality rates.
• Diagnosis is challenging due to rarity, subtle symptoms, and non-specific imaging findings.
• A high index of suspicion and prompt referral to specialized sarcoma/breast units are essential for optimal management.
