Prognosis of Patients with Cutaneous Angiosarcoma After Surgical Resection with Curative Intent: Is There a...

Area of Science:

• Oncology
• Dermatology
• Surgical Pathology

Background:

• Cutaneous angiosarcoma (cAS) has varied etiologies including idiopathic (I-cAS), radiotherapy-induced (RT-cAS), lymphedema-associated (ST-cAS), and UV-related (UV-cAS).
• Understanding oncological outcomes across these subtypes is crucial for patient management.

Purpose of the Study:

• To evaluate and compare oncological outcomes among different subtypes of cutaneous angiosarcoma.
• To identify prognostic factors influencing recurrence and survival in cAS patients.

Main Methods:

• Retrospective analysis of 234 non-metastatic cAS patients treated with curative intent surgery.
• Outcomes assessed included local recurrence (LR), distant metastases (DM), and overall survival (OS).
• Subtypes analyzed were I-cAS, RT-cAS, ST-cAS, and UV-cAS.

Main Results:

• No significant differences in LR, DM, or OS were observed between cAS subtypes.
• Age under 65 and radiotherapy administration were linked to reduced LR rates.
• Distant metastases, unlike local recurrence, significantly correlated with decreased OS.

Conclusions:

• Oncological outcomes do not significantly differ across cutaneous angiosarcoma subtypes.
• Overall survival for cAS remains suboptimal.
• Radiotherapy is associated with a reduced risk of local recurrence in cAS.
