EUTOS Score for Chronic Myelogenous Leukaemia

Predicts achievement of complete cytogenetic response (CCyR) at 18 months in CML treated with imatinib.

By palpation or ultrasound. Enter 0 if not palpable.

Score interpretation

Low Risk (EUTOS ≤ 87) 0–87

EUTOS ≤ 87: Low risk. 5-year progression-free survival 90% on imatinib (Hasford 2011).

→ Standard imatinib dosing. Monitor per European LeukemiaNet (ELN) milestones.

High Risk (EUTOS > 87) ≥ 87.01

EUTOS > 87: High risk. 34% did not reach complete cytogenetic response at 18 months on imatinib; 5-year progression-free survival 82% (Hasford 2011).

→ Consider 2nd-generation TKI upfront. Enrol in clinical trial if possible. Close monitoring of milestones.
