Naka et al developed a prognostic score for patients with angiosarcoma. This can help identify a patient who may benefit from more aggressive or novel management. The authors are from the Osaka University in Japan.
Parameters:
(1) tumor size
(2) mitotic count in 10 high power fields (HPF)
(3) treatment

where:
• Multimodal therapy consists of excisional surgery with chemotherapy, with or without radiation therapy.
• Age greater than 50 years was an additional poor prognostic finding.
prognostic score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 3
• The higher the score the worse the prognosis.
