In 2009, the International Follicular Lymphoma Prognostic Factor Project published an updated score, FLIPI2. The FLIPI2 includes the following risk factors (as with FLIPI1, each factor is worth 1 point) [9] :

  • Age >60y

  • β2-microglobulin (B2M) above the upper limit of normal

  • Bone marrow involvement

  • Hemoglobin level < 12 g/dL

  • Longest diameter of the largest involved node >6 cm
