Allogeneic stem cell transplantation in chronic myeloid leukemia patients: Single center experience

Table 1 Calculation of relative risk

	Sokal score	Hasford score	EUTOS
Calculation	0.0116 × (age - 43.4) + 0.0345 × (spleen - 7.51) + 0.188 × [(platelet count/700)2 - 0.563] + 0.0887 × (blast cells - 2.10)	0.666 when age ≥ 50 + (0.042 × spleen) + 1.0956 when platelet > 1500 × 109/L + (0.0584 × blast cells) + 0.20399 when basophils > 3% + (0.0413 × eosinophils) + 100	Spleen × 4 + basophils × 7
Risk definition	Exponential of the total	Total × 1000	Total
	Low risk: < 0.8	Low risk: ≤ 780	Low risk: ≤ 87
	Intermediate risk: 0.8-1.2	Intermediate risk: 781-1480	High risk: > 87
	High risk: > 1.2	High risk: > 1480

Age is given in years. Spleen is given in centimeters below the costal margin (maximum distance). Blast cells, eosinophils, and basophils are given in percent of peripheral blood differential. All values must be collected before any treatment. EUTOS: European Treatment and Outcome Study.
