Chemotherapy-associated neutropenia with same-day versus next-day pegfilgrastim in outpatient chemotherapy: solid tumour cohort study

Higher rates of FN were observed in the overall cohort when PGF was administered on D0, largely influenced by the subgroup of BC patients. Among OT, the day of PGF administration did not impact the outcome. These findings support the administration of PGF on D+1 of chemotherapy in BC patients when FN prevention is the objective. For patients with OT, administration of PGF on D0 is considered appropriate.
