Application of G-CSF in high-leukocyte acute myeloid leukemia is a poor prognostic factor

Abstract

Objective: To analyze the effect of granulocyte colony-stimulating factor (G-CSF) on outcomes in patients with acute myeloid leukemia (AML). Methods: A total of 526 patients with AML in the Haematology Department were enrolled. They were divided into a G-CSF treatment group and a no G-CSF group according to whether G-CSF was administered in the induction chemotherapy period, with 355 cases in the G-CSF group and 171 cases in the no G-CSF group. Cox regression analysis and Kaplan-Meier curve analysis were used to analyze the effect of G-CSF on the first complete remission (CR1) phase and overall survival (OS). In addition, further analysis was performed based on an initial white blood cell count of 50 * 10^9/L. Results: The application of G-CSF significantly shortened the CR1 phase and OS in patients with high leukocytes. Conclusions: G/GM-CSF should be used with caution in patients with AML, especially those with high leukocytes.
