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.
Parameters:
(1) age
(2) ECOG performance status
(3) serum LDH
(4) CSF protein level
(5) region of brain involvement

= SUM(points for all 5 parameters)
Interpretation:
• minimum score: 0
• maximum score: 5
• The higher the risk, the worse the prognosis.
