Demicco et al developed a risk model for patients with solitary fibrous tumor (SFT). This model can help to identify a patient who may benefit from more aggressive management. The authors are from the University of Texas M.D. Anderson Cancer Center in Houston.
Parameters:
(1) age in years
(2) diameter of tumor in cm
(3) mitotic figures per 10 high power field (hpf)

where:
• The field area for the high power field was not stated. Magnification was 400x.
• The highest mitotic count out of 3 to 5 10-field counts was used.
total score =
= SUM(points for all 3 parameters)
Interpretation:
• minimum score: 0
• maximum score: 6
• The higher the score the worse the prognosis.
