DCL, an abbreviation for donor cell leukemia, represents the occurrence of leukemia originating from the transplanted donor cells. The table includes information on ABO blood type compatibility, HLA matching, CMV status, and CHIP status. Additionally, DCL type is classified as either mixed chimerism, indicating the coexistence of recipient and donor cells, or pure donor chimerism, denoting complete replacement of recipient cells by donor cells. HLA: human leukocyte antigen; CMV: cytomegalovirus; CHIP: clonal hematopoiesis of indeterminate potential; DCL: donor cell leukemia.
