In order to analyze the clinical activity and cost-effectiveness of granulocyte colony-stimulating factors (G-CSF), the prophylactic usage of G-CSF in patients treated with a single chemotherapy regimen during early courses was prospectively evaluated.
Usage of granulocyte colony-stimulating factor every 2 days is clinically useful and cost-effective for febrile neutropenia during early courses of chemotherapy.
