[Successful treatment of CML in accelerated phase with mithramycin].

Abstract

The patient, an 18-year-old male, was admitted on May 17, 1988, because of high-grade fever, neuralgia and generalized lymphadenopathy. Bone marrow examination revealed a large number of small nests with myeloid blastic cells negative for both peroxidase and TdT activity. Ph1 chromosome and bcr rearranged fragment were positive. On a diagnosis of CML in the accelerated phase, treatment was started with standard BHAC-DMP and vincristine. However, fever still persisted and hematological improvement could not be obtained. From September 20, 1988, mithramycin was given at 25 micrograms/kg every three days. No fever was noted and the NAP score decreased. However, fever reappeared despite the continuing treatment. Combination use of vincristine (1.0 mg/week) and mithramycin (25 micrograms/kg/week) was then begun, and the fever immediately disappeared. After mithramycin administration, a transient marked increase of neutrophils appeared in the peripheral blood, suggesting the induction of differentiation. After then, a complete remission was obtained. A transient disappearance of Ph1 chromosome by the chemotherapy was noticed. He has remained in the chronic phase of CML for one year. In conclusion, combination use of vincristine and mithramycin may be useful in the treatment of the myeloid blast crisis.
