Continuous infusion of granulocyte colony-stimulating factor is associated with an advantage in neutrophil recovery in pediatric oncologic disorders
Abstract
Introduction: The use of intensified chemotherapy has significantly improved overall survival (OS) and relapse-free survival (RFS) in cancer patients. However, it also increases the risk of chemotherapy-induced neutropenia (CIN). Granulocyte colony-stimulating factor (G-CSF) is commonly used to hasten neutrophil recovery, but limited research has focused on the superiority of different routes of G-CSF administration.
Materials and methods: This was a randomized, prospective, single-institution study. Twenty-eight participants were enrolled and randomly assigned to experimental and control arms in a 1:1 ratio. At the end of the study, 20 cases were eligible for statistical analysis. The primary endpoint was the duration from the onset of neutropenia to steady neutrophil recovery. Secondary endpoints included the safety profile, 7-day emergency return rate, and the occurrence of infectious or febrile events.
Results: The mean duration from CIN to neutrophil recovery was 6.2 days in the intravenous drip (IVD) group and 7.6 days in the intravenous injection (IVI) group (P = 0.0068). The mean difference between the two groups was 1.4 days. A significantly lower incidence of febrile neutropenia (FN) was observed in the IVD group compared to the IVI group (15% vs. 50%, P = 0.0407). Adverse effects (AEs) were comparable between the two groups.
Conclusions: The IVD route of G-CSF administration leads to faster neutrophil recovery and reduces the risk of FN. All evaluable AEs are…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
