Inclusion criteria
Inclusion criteria: 1) Patients diagnosed with B-lymphoblastic leukemia / lymphoma with BCR-ABL1 (B-lymphoblastic leukemia / lymphoma with t (9; 22) (q34; q11.2): BCR-ABL1 in WHO classification revision 4th edition (2017) 2) BCR-ABL1 fusion gene positive. (1) The BCR-ABL1 fusion gene is positive by chimeric gene screening. (2) If the above 1) and 2) (1) are satisfied, the patient is diagnosed with Ph + ALL unless there is a clear record suggesting the existence of chronic phase. This is a rule that even if the major BCR-ABL1 fusion gene positive patient is BCR-ABL positive in neutrophil FISH, this test does not diagnose it as the first acute conversion case of chronic myelogenous leukemia. 3) Patients older than 15 and more and under 65 at the time of consent acquisition. 4) There is no prior treatment with this antineoplastic drug for this disease. If the administration period of prednisolone is less than one week before confirming that the BCR-ABL1 fusion gene is positive, it is not regarded as a prior treatment history. An intrathecal injection of methotrexate 12 mg/body within 1 week from the start date of prednisolone administration is not also considered to be a prior treatment history. 5) ECOG PS of 0, 1, 2, or 3. 6) Patients must have adequate cardiac, hepatic, renal, and pulmonary functions. (1) No serious abnormalities of QTc prolongation (481 msec or more, equivalent to grade 2 or more) in the electrocardiogram. (2) In cases echocardiography example, no LVEF less than 50% serious abnormalities are observed. (3) The serum bilirubin level is 2.0 mg / dL or less. (4) Serum creatinine level is 2.0 mg / dL or less. (5) Percutaneous oxygen saturation concentration is 94% or more in room air. 7) Voluntary written consent must be given before enrollment. 8) The diagnosis has been notified to the patient.
