Recombinant granulocyte colony-stimulating factor (rG-CSF): pharmacoeconomic considerations in chemotherapy-induced...

Recombinant granulocyte colony-stimulating factor (rG-CSF) therapy is associated with a dose-proportional reduction in the frequency, duration and severity of neutropenia associated with cytotoxic chemotherapy. This is associated with a decrease in the incidence of infection, with subsequent reductions in the number of hospitalisations, days of hospitalisation and antibiotic requirements. These effects produce marked reductions in costs, and could contribute substantially towards offsetting the costs of rG-CSF, although the magnitude of the savings will vary between institutions and with the chemotherapy regimen used. Other benefits include a reduction in the frequency and severity of mucositis, and an improved patient quality of life. However, further research is required to evaluate other potentially important considerations including the targeting of specific patient populations (e.g. those receiving regimens with a curative intent), and additional improvements in patient quality of life and, perhaps, mortality. Thus, although specific pharmacoeconomic analyses are limited, preliminary evidence indicates that rG-CSF, administered prior to the onset of neutropenia in patients receiving cytotoxic chemotherapy, can provide cost reductions both from an institutional and a payor perspective, with even greater potential savings from a societal viewpoint.
