Popis: A 52-year-old man was admitted for treatment of acute lymphoblastic leukemia (ALL). The bone marrow was hypercellular with 67.2% blasts, which were negative for peroxidase, and expressed CD13, CD33, CD34, CD10 and CD7. Cytogenetic and molecular studies revealed t(9;22) and -7(Ph/-7) with major BCR/ABL rearrangement. The patient was treated with the L-AdVP regimen, but failed to achieve complete remission (CR). He then received two courses of chemotherapy consisting of intermediate- and high-dose cytarabine (ara-C), resulting in CR. This case suggests that Ph/-7 ALL with major BCR/ABL gene rearrangement showing coexpression of myeloid antigens may be sensitive to intermediate- and high-dose ara-C.
