CSF3 and infection: Routine use of MGF to prevent infection is not recommended for patients with MDS (National Comprehensive Cancer Network [NCCN] Clinical Practice Guidelines, 2016), however, for patients with active infections or neutropenic fever, MGF, granulocyte colony-stimulating factors filgrastim (Neupogen) and pegfilgrastim (Neulasta), can be safely administered to patients concurrently with lenalidomide and might limit the severity of infections and the need for repeated dose reductions of lenalidomide (Kurtin & Sokol, 2006).
