Abstract:
Objective:To retrospectively analyze efficacy and safety of granulocyte colony-stimulating factor(G-CSF)in relapsed/refractory B cell acute lymphoblastic leukemia(R/R B-ALL)patients with neutropenia(NE)after receiving CAR-T cell therapy.Methods:From March 2017 to December 2022,99 patients with R/R B-ALL developed NE after receiving CAR-T cell therapy in Tianjin First Central Hospital were collected and divided into two groups according to using time of G-CSF.One was early G-CSF group(received G-CSF within 7 days,n=56),the other was control group(received G-CSF after 7 d,n=43),whose recovery of NE and occurrence of adverse reactions after G-CSF were compared.Results:Duration of NE in early G-CSF group was shorter than control group[4(2,5.7)vs 11(9,14),P<0.05],but there were no significant differences in the lowest absolute neutrophil count(ANC),degree of NE inhibition and incidence of infection(P=0.261,P=0.09,P=0.111).There was no significant difference between incidence and severity of cytokine release syndrome(CRS)between two groups,and CRS was controllable in all patients.Conclusion:Early application of G-CSF in R/R B-ALL patients after CAR-T cell therapy can shorten duration of NE,and has no significant effect on adverse reactions after CAR-T cells.
