Abstract Patients with primary refractory or relapsed acute myeloid leukemia (AML) who undergo intensive salvage chemotherapy carry a high risk of treatment failure due to infectious complications and early relapses. The study presented here assessed the effect of granulocyte colony-stimulating factor (G-CSF) on the duration of post-treatment neutropenia, the incidence of infection-related deaths, and the disease-free and overall survival. Sixty-eight evaluable patients with relapsed and refractory AML received G-CSF 5 μg/kg per day subcutaneously starting 2 days after the completion of salvage treatment with the S-HAM regimen, consisting of high-dose cytosine arabinoside twice daily on days 1, 2, 8, and 9 and mitoxantrone on days 3, 4, 10, and 11. Ninety-one patients who were treated with the identical S-HAM regimen but without G-CSF support during a preceding study served as controls. The application of G-CSF resulted in a significant shortening of critical neutropenia of less than 500 μl (36 vs. 40 days;p=0.008), which translated into a trend towards a lower early death rate (21% vs. 30%) and an increase of complete remissions (56% vs. 47%, p=0.11). In patients younger than 60 years a significant prolongation of time to treatment failure (159 vs. 93 days, p=0.038) and of duration of disease-free survival (203 vs. 97 days, p=0.003) was observed. These results indicate a beneficial effect of G-CSF on early mortality as well as on long-term outcome when administered after S-HAM salvage therapy for advanced AML.
