Abstract;G-CSF has been demonstrated to be effective on leukopenia induced by cancer chemotherapy. The author administered nartograstim subcutaneously at a dose of 50 .MU.g in one course of cancer chemotherapy in 7 patients, 3 with ovarian tumor, 2 with uterine corpus cancer, and 2 with uterine cervical cancer, receiving two or more courses of the same chemotherapy. The necessity of administering G-CSF for consecutive days was studied by comparing the recovery of leukopenia between consecutive- and alternate-day regimens. The duration from the nadir to .GEQ.2000/mm3 or .GEQ.3000/mm3 of leukocyte count and the time-course profile at measuring points were superior by consecutive-day regimen than by alternate-day regimen. However, there was no statistically significant difference in any endpoint or in the time of dosing G-CSF. No infection occurred by consecutive- or alternate-day regimen. The administration of G-CSF on alternate days to treat myelosuppression induced by cancer chemotherapy seems to be a choice of regimen depending on leukocyte status of patients. (author abst.)
