title: Two cases of acute myelogenous leukemia with high terminal deoxynucleotidyl transferase activity responding to vincristine-prednisolone treatment with complete remission.
abstract: Increased TdT activity was demonstrated in 2 cases of AML. One of them had Ph1 positive chromosome due to a standard translocation of t(9:22). Treatment with cytosine arabinoside, daunorubicin, 6-mercaptopurine and prednisolone was ineffective or only partially effective. Switching to the vincristine and prednisolone therapy resulted in a complete remission in both cases.
