Oncology practice patterns in the use of hematopoietic growth factors.

Recombinant hematopoietic growth factors were introduced into clinical practice a decade ago: erythropoietin in 1989, granulocyte colony-stimulating factor (G-CSF) and granulocyte-macrophage colony-stimulating factor (GM-CSF) in 1991, and interleukin-11 in 1997. The role of these agents in supportive therapy for children with cancer is still under considerable evaluation. This pediatric-based review summarizes current clinical applications, practice guidelines, and practice patterns for hematopoietic growth factors in the supportive care of children with cancer. It also discusses ongoing controversies and unanswered questions.
