Chronic Lymphocytic Leukemia International Prognostic Index

Chronic Lymphocytic Leukemia International Prognostic Index

Risk Category*

Points

Treatment

Low risk

(0–1 points)

No treatment recommended

Intermediate risk

(2–3 points)

No treatment recommended, unless patient is symptomatic

High risk

(4–6 points)

Treatment recommended, unless the patient is asymptomatic

Very high risk

7–10 points

Treatment with novel agents or in a clinical trial (preferred over chemotherapy)

CLL-IPI Prognostic Factor Point Value: Age > 65 years = 1 point; CLL-IPI Prognostic Factor Point Value: Rai stage I-IV or Binet stage B-C = 1 point; Unmutated IGHV = 2 points; serum beta-2 microglobulin > 3.5 mg/L = 2 points; TP53 mutation or deletion 17p = 4 points.

* For each CLL-IPI risk category, the overall survival (without treatment) at 5 years (p < 0.001 for all) is estimated to be: low-risk: 93% (95% CI 91-96); intermediate risk: 79% (95% CI 76-83); high risk: 63% (95% CI 58-69); very-high risk: 23% (95% CI 13-34)

CLL = chronic lymphocytic leukemia; IGHV = immunoglobulin heavy chain variable region; IPI = international prognostic index.
