Abstract:
Use of growth factors (G-CSF/GM-CSF) as adjunct in induction therapy of AML is controversial. Possible stimulation of leukemia cell clones has been the major cause of concern. We treated 50 cases of AML with GM-CSF as an adjunct during induction therapy. 35 patients (70%) achieved complete remission out of which 13 patients relapsed at a median relapse period of 15 months. Average duration of neutropenia was 10.5 days. (15 days in the control) Febrile episodes were fewer and antibiotic support was required for an average period of only 7.6 days (16.9 days in the control). The benefits including the economic analysis of the role of GM-CSF in this setting is discussed.
