Abstract
Hematopoietic growth factors, including granulocyte colony-stimulating factor (G-CSF), are being increasingly used to prevent chemotherapy-induced neutropenia. We report a patient with aggressive non-Hodgkin's lymphoma who was successfully supported with G-CSF through a weekly VACOP-B chemotherapy regimen. The patient had become severely neutropenic at week 3, requiring a one-week delay. For the remainder of the treatment, G-CSF at a dose of 4 μg/kg/day was administered daily over 4 days after week 4, then over 3 days thereafter, beginning the day after the non-myelosuppressive weeks (vincristine/bleomycin). A total of 5 such G-CSF courses were given, with no further neutropenia despite administration of full chemotherapy doses on schedule. This case suggests that, at least with the VACOP-B regimen, chemotherapy-induced neutropenia can be prevented using much lower quantities of G-CSF than has been reported using other regimens.
