This phase 2 trial will explore the efficacy of a single dose of vinblastine (6mg/m2) to leukoreduce patients with newly diagnosed AML and hyperleukocytosis. Patients will be allocated 1:1 into two groups: intravenous single dose vinblastine or oral hydroxiurea (50mg/kg/day until response or induction chemotherapy). Effective leukoreduction and safety parameters will be compared.
Vinblastine can leukoreduce patients with newly diagnosed AML and hyperleukocytosis but clinical trials are lacking.
