Introduction: Granulocyte colony stimulating factors (G-CSF), including filgrastim and pegfilgrastim, are associated with bone pain, potentially impacting treatment adherence. This study hypothesized that a 5-day regimen of filgrastim (5-day-FIL) would result in less bone pain than single-dose pegfilgrastim (PEG) in patients receiving chemotherapy for early breast cancer.
Methods: In this multicenter, open-label, randomized controlled trial, patients requiring prophylactic G-CSF during chemotherapy were randomized 1:1 to receive either 5-day FIL or PEG.

Background: Febrile neutropenia (FN), a major hematologic adverse event in perioperative chemotherapy for breast cancer, is more prevalent among Asian populations than Caucasians. Hematopoietic growth factor guidelines recommend pegfilgrastim for primary prophylaxis based on chemotherapy regimen and patient risk factors. We verified the appropriateness of these guidelines for patient selection.

Objectives: Large trials and meta-analyses in adults suggest a similar efficacy and safety of a single dose of peg-filgrastim compared with daily filgrastim in the prevention of chemotherapy-induced neutropenia. However, there is no large prospective data in the pediatric population. This trial was designed to demonstrate the efficacy and safety of peg-filgrastim in children.
