FLIPI Follicular Lymphoma International Prognostic Index

Calculates the Follicular Lymphoma International Prognostic Index (FLIPI) using 5 adverse factors: age >60, Ann Arbor stage III–IV, hemoglobin <12 g/dL, >4 nodal areas involved, and elevated LDH. Scores 0–5 define low (0–1), intermediate (2), or poor (3–5) risk.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates the Follicular Lymphoma International Prognostic Index (FLIPI) using 5 adverse factors: age >60, Ann Arbor stage III–IV, hemoglobin <12 g/dL, >4 nodal areas involved, and elevated LDH. Scores 0–5 define low (0–1), intermediate (2), or poor (3–5) risk

Each component has a specific meaning:

  • 5 adverse factors: age >60 — The 5 adverse factors: age >60 recorded for the scenario being assessed.
  • Ann Arbor stage III–IV — The ann arbor stage iii–iv recorded for the scenario being assessed.
  • Hemoglobin <12 g/dL — The hemoglobin <12 g/dl recorded for the scenario being assessed.
  • >4 nodal areas involved — The >4 nodal areas involved recorded for the scenario being assessed.
  • Elevated LDH — The elevated ldh recorded for the scenario being assessed.

Note: Interpret the flipi score result against the thresholds and context described above.

How to Use

Enter the 5 adverse factors: age >60, Ann Arbor stage III–IV, hemoglobin <12 g/dL, >4 nodal areas involved, elevated LDH for the scenario you are assessing. Calculates the Follicular Lymphoma International Prognostic Index (FLIPI) using 5 adverse factors: age >60, Ann Arbor stage III–IV, hemoglobin <12 g/dL, >4 nodal areas involved, and elevated LDH. Scores 0–5 define low (0–1), intermediate (2), or poor (3–5) risk. Use the flipi score result to inform your calculation.
