Abstract excerpt
Loss of mismatched HLA is a cause of relapse following HLA-mismatched allo-SCT. We directly detected the loss of mismatched HLA alleles in relapsed leukemic cells at a MRD level using HLA typing by multicolor FACS (HLA-Flow) in combination with FISH in the BM of two patients with MLL-AF9-positive AML, at 6 and 10 months after mismatched allo-SCT. HLA-Flow with FISH analysis detected relapsed leukemic cells not...
