Clinical Effects of Arsenic Trioxide by Slowing-intravenous Infusion on Acute Promyelocyte Leukemia

Although As2O3 is effective in the treatment of acute promyelocytic leukemia (APL), some side effects, such as leukocytosis which can increase the incidence of cerebral hemorrhage and early death rate, often occur during the early stage of As2O3 treatment. In this paper, the advantages of continuously slow intravenous As2O3 infusion on relieving leukocytosis and decreasing the incidence of cerebral hemorrhage and early death rate were observed clinically.
