High class II-associated invariant chain peptide expression on residual leukemic cells is associated with increased relapse risk in acute myeloid leukemia
2014
Abstract The presence of class II-associated invariant chain (CLIP) on leukemic cells is negatively associated with clinical outcome in untreated acute myeloid leukemia (AML). CLIP plays a role in the immune escape of leukemic cells, suggesting that it impairs the immunogenicity of minimal residual disease (MRD) cells causing a relapse. Here, we demonstrate that CLIP expression on leukemia-associated phenotype (LAP)-positive cells during follow-up is significantly correlated with a shortened relapse-free survival, even in those patients who are generally considered as MRD low (0.01–0.1% LAP + cells). Consequently, CLIP evaluation could be of additional value in the evaluation of MRD to predict a relapse of AML.
