Abstract
Patients with primary refractory or early relapsed acute myeloid leukemia (AML) have a dismal prognosis, and the treatment options for these patients are limited. The present study retrospectively examined the efficacy and toxicities of the combination of cladribine 5 mg/m2 per day and intermediate-dose cytarabine 1 g/m2 per day for 5 days and granulocyte colony–stimulating factor (G-CSF) as a salvage treatment in 36 patients with relapsed/refractory AML. Among these, 32 patients had de novo AML, and the remaining 4 patients had secondary AML. The median age for the study cohort was 45.8 years. According to the European LeukemiaNet prognostic index, 5 patients had favorable risk, 18 had intermediate risk, and 11 had poor risk. The complete remission was achieved in 58% of the patients with tolerable toxicities. Fifteen patients underwent stem cell transplantation later. Patients who underwent allogeneic hematopoietic stem cell transplantation had a significantly improved 1-year overall survival compared with those who did not (73% vs. 29%, P < 0.001). The results suggested that, as a salvage regimen, modified cladribine, cytarabine, and G-CSF were effective and well tolerated for patients with relapsed/refractory AML, especially for patients who underwent subsequent stem cell transplantation.
