Clinicopathological features of breast angiosarcoma

Area of Science:

• Oncology
• Surgical Pathology

Background:

• Breast angiosarcomas are rare neoplasms with limited therapeutic strategies.
• Investigating clinicopathologic features and treatment outcomes is essential due to rarity.

Purpose of the Study:

• To investigate the clinicopathologic features of breast angiosarcoma.
• To examine treatment strategies and compare outcomes with existing literature.

Main Methods:

• Retrospective chart and slide review of patients diagnosed with primary or secondary breast angiosarcoma.
• Data collected from 1997 to 2012 at the National Cancer Center Hospital, Tokyo, Japan.

Main Results:

• Nine patients diagnosed: six primary, three secondary breast angiosarcomas.
• Primary angiosarcoma: median age 39, median tumor size 6.78 cm. 5-year survival rate was 50%.
• Secondary angiosarcoma: all cases recurred; one achieved long-term survival with local control therapy.

Conclusions:

• Breast angiosarcoma exhibits high recurrence rates.
• Tumor size and surgical margins are critical for long-term survival.
• Total mastectomy with adequate margins and early detection are recommended; local recurrence may be curable with surgery.
