A Prospective, Open-label, Randomized Controlled, Multicenter Clinical Study of MSD-HSCT Using a TBI or TMLI Conditioning Regimen for Adult ALL
This study aims to compare the effects of two different conditioning regimens on patients with acute lymphoblastic leukemia (ALL) undergoing matched sibling donor hematopoietic stem cell transplantation (MSD-HSCT): Total Body Irradiation (TBI) and Total Marrow, Central Nervous System and Lymphoid Irradiation (TMLI). Both regimens are supported and recommended by literature; however, there is no definitive evidence favoring one over the other. We hypothesize that the TMLI regimen, compared to the TBI regimen, may more effectively eliminate leukemia cells in the bone marrow and lymphoid tissues,
