Research Progress on Role of Gene Mutations in Prognostic Evaluation of Patients with Myelodysplastic Syndrome after Stem-Cell Transplantation--Review / 中国实验血液学杂志

ABSTRACT

Abstract　　Myelodysplastic syndromes (MDS) represent a clonal hematopoietic stem cell disorder characterized by morphologic features of dyspoiesis, high risk of transformation from MDS into AML. Allogeneic hematopoietic stem-cell transplantation is the only curative therapy for MDS, but the failure rate of transplantation is still high, which attribute to relapsed disease and transplant-related complications. Recently, the spectrum of gene abnormalities in MDS has been revealed by next generation genomic sequencing techniques. It was found that more than 80% MDS patients have at least one gene mutation. Mutated genes in MDS are powerfully associated with clinical phenotype and prognosis. In this review , the recent advancements regarding recurrent gene mutations in MDS are briefly summarized, and the  prognostic values of gene mutations are discussed in MDS or after allogeneic hematopoietic stem-cell transplantation,so as to set up a predicting model and to guide the treatment.
