We designed a novel panel of antibodies to identify aberrant differentiation\/maturation profiles of residual leukemia cells in patients who were not diagnosed at our institution, relapsed with an antigenic shift, or lack leukemia\u2010associated immunophenotypes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We compared the MRD status detected using MFC and real\u2010time quantitative polymerase chain reaction (RT\u2010qPCR) in the same 158 bone marrow samples collected from 44 AML patients carrying leukemia\u2010specific fusion genes. The clinical performance of the MFC\u2010based MRD status was analyzed in 168 AML patients who exhibited morphologic CR (135) or active disease (33) before HSCT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Strong concordance was found between MFC\u2010based and RT\u2010qPCR\u2010based MRD status (<jats:italic>\u03ba<\/jats:italic>\u00a0=\u00a00.868). Among the patients displaying CR, the positive MRD status detected using MFC was correlated with a worse prognosis [HRs (<jats:italic>P<\/jats:italic> values) for relapse, event\u2010free survival, and overall survival: 4.83 (&lt;0.001), 2.23 (0.003), and 1.79 (0.049), respectively]; the prognosis was similar to patients with an active disease before HSCT.
