Autologous or allogeneic HSCT may be considered medically necessary to treat childhood ALL in second or greater remission or refractory ALL.

In patients with cytopenia(s), the presence of clonal cytogenetic abnormalities, except for +8, del(20q) and −Y, can serve as presumptive evidence of myelodysplastic syndrome.

Philadelphia chromosome during therapy of acute leukemia and myelodysplastic syndrome is rare. We reported 19 patients, including 11 men and 8 women with a median age of 53 years at initial diagnosis.

3. Acute myelogenous leukemia (AML) comprises about 20%, chronic myelogenous leukemia (CML) comprises about 3% of childhood leukemia cases. Other rare myeloid leukemias account for 1-2% of cases. 4. AML incidence peaks in first 2 years of life, declines to a nadir at 9 years and increases slowly thereafter during the adolescent years. 5.

Thrombocytosis is classified according to its cause as primary or secondary (3). The so-called primary thrombocytosis or thrombocythemia is observed in chronic myeloproliferative disorders, but also in some myelodysplasias, e.g., 5q syndrome. The most common disorder with primary thrombocytosis is ET. Thanks to including bone marrow histology
