Follicular Lymphoma International Prognostic Index (FLIPI) Calculator      
Prognostic score for newly-diagnosed follicular lymphoma      
Applies at the time of diagnosis.
  Value Points     1. Sum the number of risk factors to calculate the FLIPI score
Age (years)
Age:  < 60 years  60 years or older
Raised LDH
Lactate dehydrogenase (LDH):  Normal  Raised
nodal areas involved (number)
Number of nodal areas involved:  4 or fewer  5 or more
Ann Arbor stage
Ann Arbor stage:  I or II  III or IV
Hemoglobin (g/dL)
Hemoglobin:  12 g/dL or greater  < 12 g/dL
          2. Determine risk category and prognosis
FLIPI score Risk category % of patients1 Median PFS (m)2
Sum of score     0 or 1 Good 36 84
Risk category     2 Inter­mediate 37 70
3 - 5 Poor 27 42
