Abstract
Allogeneic hematopoietic stem cell transplantation (HSCT) plays a key role in treatment of hematological malignancies. However, relapse of hematological malignancies is the main challenge of HSCT that causes significant declination of overall survival (OS) after HSCT. In recent years, the newly emerging chimeric antigen receptor T-cell (CAR-T) immunotherapy has obtained remarkable achievements in hematological malignancies, and with the progress of research, the safety and effectiveness of CAR-T are also increasing. Studies have found that donor-derived CAR-T can significantly increase OS rates in relapsed patients after transplantation through and control disease recurrence and progression. This review will focus on the efficacy and safety of donor-derived CAR-T in relapsed hematological malignancies after allo-HSCT, and summarize the main challenges to be resolved. Key words: Hematologic neoplasms; Hematopoietic stem cell transplantation; Recurrence; Donor-derived; Chimeric antigen receptor T-cell
