HASFORD Score Calculator          
  Value Points     1. Sum the points for each risk factor
Age (years)*
[(0.6666 x age [0 when age < 50 years; 1 otherwise]) + (0.0420 x spleen size [cm]) + (0.0584 x blasts [%]) + (0.0413 x eosinophils [%]) + (0.2039 x basophils [0 when basophils < 3%; 1 otherwise]) + (1.0956 x platelet count [0 when platelets < 1500 x 109/L; 1 otherwise]) x 1000]
Spleen size (cm below costal margin)*
Platelet count (x 109/L)*
Peripheral blood blasts (% of leukocytes)*
Peripheral blood eosinophils (% of leukocytes)*
Peripheral blood basophils (% of leukocytes)*
          2. Assign risk category and determine prognosis
Hasford score       low-risk (score ≤ 780)
Hasford risk group       intermediate-risk (score 781 – 1480)
