Prognostic significance of minimal residual disease assessed by flow cytometry in acute myeloid leukemia
Abstract
Despite high complete remission rate after induction chemotherapy, long-term prognosis for acute myeloid leukemia (AML) patients is still unsatisfactory. Leukemic blast cells remaining after therapy, which cannot be detected by standard method for response assessment in AML, termed minimal residual disease (MRD) are responsible for frequent relapses. High sensitivity methods, e.g. flow cytometry are being widely studied for MRD monitoring. Majority of studies confirm this parameter to be an independent risk factor for relapse and death in AML. What is more, MRD assessment is thought to be complementary to cytogenetic and molecular aberrancies in risk stratification and applying more adequate risk-adapted therapy. However, lack of method standardization is an obstacle to its incorporation into clinical practice.
