What is the risk in G-CSF treatment for severe congenital neutropenia?
Severe congenital neutropenia is a rare hematological condition causing severe chronic neutropenia. Treatment with the myeloid growth factor, granulocyte-colony stimulating factor (G-CSF) is usually effective, but the dose of G-CSF required to normalize blood neutrophils varies greatly. Ten to thirty percent of the patients evolve to develop acute myeloid leukemia or myelodysplastic syndromes, necessitating careful clinical monitoring.
