The challenge for allogeneic hematopoietic stem cell transplantation in acute leukemia/ myelodyplastic syndrom with TP53, TET2 or DNMT3A gene mutations / 天津医药

ABSTRACT

@#Recently, much gene mutations have been detected in patients with acute leukemia or myelodysplastic syndrome (MDS) using next-generation sequencing (NSG) technology. Some of them are proved to be important prognostic markers. It has been showed that TP53, TET2 or DNMT3A gene mutations are associated with poor prognosis in acute leukemia or MDS patients. The prognosis of these patients is poor with short remission and survival. Allogeneic hematopoietic stem cell transplantation is the only way to cure these patients. However, the outcomes after transplantation are inferior to those in patients without these mutations. The hypomethylating agents or immune targeting therapy might improve their prognosis when combined with the present strategies. Here, the impact of TP53, TET2 and DNMT3A gene mutations on the prognosis after chemotherapy or transplantation is reviewed.
