After 3 months, progression to sAML was observed: WBC of 24.1 × 109/L with an increased percentage (40%) of polymorphic blasts, 1% promyelocytes, 2% myelocytes, 10% metamyelocytes, 30% neutrophils, 1% eosinophils, 4% basophils, 4% lymphocytes, and 8% monocytes, accompanied by severe anemia (Hb 5.8 g/dL) and normal PLT count. This evidence concerns the gene GSTM1 and anemia (phenotype).
