The association between nonleukemic death and various features recorded at presentation in patients with refractory anemia (RA), RA with ring sideroblasts, and RA with excess of blasts was analyzed in 251 patients using the proportional hazards model. Features associated with higher nonleukemic death rates were: 1% or more metamyelocytes in peripheral blood (PB); lower 59Fe incorporation rate; 1% or more blasts in PB; lower hematocrit or hemoglobin; presence of giant platelets; 1 microgram… CONTINUE READING
