Description

Ferreri et al developed a prognostic score for patients with primary CNS lymphoma. This can help identify those patients who may benefit from more aggressive or who may be a candidate for investigational therapy. The authors are from the International Extranodal Lymphoma Study Group.

total score =

= SUM(points for all 5 parameters)

 

Interpretation:

• minimum score: 0

• maximum score: 5

• The higher the risk, the worse the prognosis.
