Research advances in value of flow cytometric immunophenotyping in diagnosis and prognostic evaluation of myelodysplastic syndrome / 中国实验血液学杂志

ABSTRACT

Myelodysplastic syndromes (MDS) are myeloid neoplasms characterized by dysplasia in one or more linages of cells and increased risk of development of acute myeloid leukemia (AML). Along with the deeply understanding of myelodysplastic syndrome, the diagnosis standards of this disease experienced a leap in essence: from a single standard of morphological test in FAB to multiple detecting means in WHO standard of 2008, flow cytometry has been proposed as an adjunctive diagnostic test in the 2007 Vienna standards and the 2008 WHO standards. Recently, A heterogeneous spectrum of immunophenotypic abnormalities have been reported in MDS, and some of which are of great significance to the diagnosis, classification, prognosis assessment, and treatment of the disease. In the year of 2003, a flow cytometric scoring system (FCSS) was built to evaluate the prognosis of MDS patients, which was able to qualify the phenotypic aberrancies in the myelomonocytic, erythroid, and megakaryocytic lineage. It filled the gap of the international prognostic scoring system (IPSS) and the WHO classification-based prognostic scoring system (WPSS), and was of great value to the clinical diagnosis and treatment of MDS. In this article, the value of MDS immunophenotyping in diagnosis and prognosis evaluation of MDS is reviewed in term of MDS immunophenotypic abnormalities and flow cytometric scoring system.
