The clinical utility of granulocyte colony-stimulating factor: early achievements and future promise.
Recombinant granulocyte colony-stimulating factor (rHuG-CSF) is a hematopoietic growth factor that acts selectively on the neutrophil lineage, and has had a major impact on clinical practice. Two forms are in clinical use: filgrastim has been approved for use in more than 45 countries for the amelioration of chemotherapy-induced neutropenia and restoration of granulopoiesis following bone-marrow transplantation and lenograstim has been approved in Europe and Japan. In some countries, rHuG-CSF is also approved for various other indications, such as severe chronic neutropenia. Infection and neutropenia are a major cause of morbidity and mortality following cytotoxic chemotherapy, and there is a known correlation between neutropenia and the risk of infection. Hematopoietic growth factors have been used successfully in the prevention and treatment of neutropenia. There is evidence to suggest that use of rHuG-CSF before the onset of neutropenia allows patients to receive the maximum benefit; however, patients who do not receive rHuG-CSF prophylactically still benefit from the use of rHuG-CSF for the treatment of febrile neutropenia. These patients have an accelerated neutrophil recovery and a shorter duration of febrile neutropenia. These effects seem to translate into a significant reduction in the number of patients requiring prolonged hospitalization. This paper reviews the use of rHuG-CSF in the treatment of febrile neutropenia and describes how it is routinely used by hematologists and oncologists in non-clinical trial settings.
