BALL Score for Relapsed/Refractory CLL

Predicts overall survival in previously treated (relapsed/refractory) CLL starting targeted therapy or chemoimmunotherapy (Soumerai 2019). Four factors, 1 point each: 0–1 low, 2–3 intermediate, 4 high risk.

Score interpretation

Low Risk (BALL 0–1) 0–1

24-month overall survival 89.7% (training cohort, Soumerai 2019).

→ Prognostic only — the score does not decide whether to treat (iwCLL 2018 criteria). Treat per guideline; consider clinical trials.

Intermediate Risk (BALL 2–3) 2–3

24-month overall survival 79.5% (training cohort).

→ The authors encourage clinical trial participation for intermediate- and high-risk patients; choose therapy per guideline and MDT.

High Risk (BALL 4) 4

24-month overall survival 55.8% (training cohort).

→ Clinical trial strongly encouraged (novel combinations, CAR-T); MDT discussion, including allogeneic transplant evaluation in fit patients.

Interpretation bands for the BALL Score. Apply clinical judgement and local guidance.
