BuCY vs TBICY Conditioning Regimen for Standard-risk ALL Undergoing Allo-HSCT

March 30, 2022 updated by: Qifa Liu, Nanfang Hospital of Southern Medical University

Busulfan Plus Cyclophosphamide vs Total Body Irradiation Plus Cyclophosphamide Conditioning Regimen for Standard-risk Acute Lymphocytic Leukemia Undergoing HLA-matched Allogeneic Hematopoietic Stem Cell Transplantation

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) appears to be an efficient tool to cure standard-risk acute lymphocytic leukemia (ALL) in first CR (CR1) but the choice between BU-based or TBI-based conditioning regimens still remains controversial. In this study, the safety and efficacy of BUCY and TBICY myeloablative conditioning regimens in patients undergoing allo-HSCT for ALL in CR1 are evaluated.

Detailed Description

Allo-HSCT appears to be an efficient tool to cure standard-risk ALL in CR1. The conditioning regimen with BUCY or TBICY is considered as the standard myeloablative regimen for ALL in CR1, but the choice between BU-based or TBI-based conditioning regimen still remains controversial.In order to analyze the impact of conditioning regimen on long-term survival and relapse, in this study, the safety and efficacy of BUCY and TBICY myeloablative conditioning regimens in patients undergoing allo-HSCT for ALL in CR1 are evaluated.
