Her hemoglobin was 10.5 g/dl, platelet count 237 X 109 / L and total leukocyte count 40 X 109 /L, which included 80% mature lymphoid cells with coarse clumped chromatin. Bone marrow revealed a nodular lymphoid infiltrate. The peripheral blood lymphoid cells were positive for CD19, CD5, CD20, CD23 and were negative for CD79B and FMC-7.

On examination, liver and spleen were enlarged 4 cm and 3 cm respectively below the costal margins. His hemoglobin was 10.0 g/dl, platelet count 37 x 109/L and total leukocyte count 70 x 109/L, which included 80% eosinophils. Bone marrow examination revealed a cellular marrow comprising 45% blasts and 34% eosinophils and eosinophilic precursors. The blasts stained negative for myeloperoxidase and non-specific esterase¬ and were positive for CD 19, CD 10, CD22 and CD20. Which one of the following statements in not true about this disease ?
