Treatment of the blastic phase of chronic myelogenous leukemia with mitoxantrone and high-dose cytosine arabinoside.
Twenty-seven patients in the blastic phase of chronic myelogenous leukemia received combination chemotherapy with mitoxantrone 5 mg/m2 intravenously daily for 5 days, and cytosine arabinoside 3 g/m2 intravenously over 2 hours every 12 hours for six doses. The patients' median age was 42 years (range, 19-61 years), and 26 of them had Philadelphia chromosome-positive disease. Overall, seven patients (26%) achieved complete remission, and one (4%) had a partial remission for an overall response rate of 30%. Eight patients died during remission induction, and 11 had resistant disease. The median survival was 14 weeks for the total population, and 24 weeks for patients achieving a complete remission. The nonmyelosuppressive toxicity of the combination was acceptable; serious neurologic and pulmonary toxicities were uncommon. Significant marrow hypoplasia was observed resulting in a high incidence of febrile episodes (85% of patients). The combination of mitoxantrone and high-dose cytosine arabinoside did not significantly improve overall prognosis. Since chemotherapy continues to produce disappointing results, other innovative approaches need to be explored.
