Review Case ReportsDonor-derived CAR-T Cells Serve as a Reduced-intensity Conditioning Regimen for Haploidentical Stem Cell Transplantation in Treatment of Relapsed/Refractory Acute Lymphoblastic Leukemia: Case Report and Review of the Literature.
Reduced-intensity conditioning (RIC) regimens with low tolerable toxicities have been used for allogeneic hematopoietic stem cell transplantation (allo-HSCT). However, the relapse rate by this treatment is high. Treatment of CD19 B-cell relapsed/refractory acute lymphoblastic leukemia (r/r ALL) with allogeneic chimeric antigen receptor-modified T (CAR-T) cells is safe and effective. Use of allogeneic CD19-CAR-T cells as a part of RIC regimens for treatment of r/r ALL patients with haploidentical HSCT has not been investigated yet. ⋯ Treatment of r/r ALL with RIC including CD19-CAR-T cells followed by allo-HSCT was safe and effective, which suggest that CAR-T cells can be used as a part of RIC regimens in the treatment of r/r ALL in haploidentical HSCT.
