General description
The tool calculates prognostic risk group of the EUTOS long-term survival score (ELTS), Sokal and Euro (Hasford) scores for adult patients diagnosed with chronic myeloid leukemia (CML). The score is calculated from patient age, spleen size, blasts in peripheral blood and platelet count. Based on the risk score the patient is assigned to one of the three groups: low-risk, intermediate-risk and high-risk group.

ELTS score =
0.0025 × (age in completed years/10)³
+ 0.0615 × spleen size below costal margin
+ 0.1052 × blasts in peripheral blood
+ 0.4104 × (platelet count/1000)⁻½

Sokal score =
exp ((0.0116 × (age [years] – 43.4))
+ (0.0345 × (spleen size [cm] – 7.51))
+ (0.188 × ((platelets [10⁹/L]/700)² – 0.563))
+ (0.0887 × (blasts % – 2.10)))

Hasford score =
((0.6666 × age [0 when age < 50 years; 1 otherwise])
+ (0.0420 × spleen size [cm])
+ (0.0584 × blasts %)
+ (0.0413 × eosinophils %)
+ (0.2039 × basophils [0 when basophils < 3%; 1 otherwise])
+ (1.0956 × platelet count [0 when platelets < 1500 × 10⁹/L; 1 otherwise])) × 1000
