The scoring system of Sanz et al for myelodysplasia uses the patient's age, platelet count and per cent bone marrow blasts to separate patients into prognostic groups and to predict likely survival time.
Parameters:
(1) platelet count per µL
(2) percent blasts in the bone marrow
(3) age of the patient in years
