摘要: 目的 探讨MDS、MDS/AML及原发AML基因突变频谱的异同点及其临床意义。方法 选取98例MDS患者、32例MDS/AML患者及234例原发AML患者为研究对象,利用二代测序技术检测基因突变。结果 MDS组中突变率较高的基因突变为TET2(16.7%,16/96)、U2AF1(12.0%,6/50)、SF3B1(11.8%,9/76);MDS/AML组中突变率较高的基因突变为TP53(33.3%,2/6)、DNMT3A(30%,6/20)、IDH2(21.1%,4/19);原发AML组中突变率较高的基因突变为FLT3-ITD(18.0%,42/233)、NPM1(16.3%,38/233)、DNMT3A(14.9%,14/94)。DNMT3A(P=0.006)、IDH2(P=0.004)及NPM1(P=0.002)等基因突变在MDS与MDS/AML两组间的突变率有统计学差异;FLT3-ITD(P=0.001)、NPM1(P=0.002)、CEBPA(P=0.011)及IDH2(P=0.019)等基因突变在MDS与原发AML两组间的突变率有统计学差异;所有受检基因突变在MDS/AML与原发AML两组间的基因突变的突变率无统计学差异(P>0.05)。结论 MDS、MDS/AML及原发AML基因突变的突变频谱具有相似性及异质性,从MDS到MDS/AML、原发AML基因突变的变化不仅影响疾病转归及预后而且可帮助鉴别MDS/AML和原发AML。

Abstract: Objective To explore the similarities and differences of spectrum of gene mutations in patients with myelodysplastic syndrome, MDS/AML and de novo acute myeloid leukemia and their clinical significance. Methods 98 patients with MDS, 32 patients with MDS/AML, 234 patients with de novo AML were selected. Gene mutations were detected by second generation sequencing. Results The most frequent mutations in MDS were as follows:TET2(16.7%, 16/96), U2AF1(12.0%, 6/50), SF3B1(11.8%, 9/76); The most frequent mutations in MDS/AML were TP53(33.3%, 2/6), DNMT3A(30%, 6/20), IDH2 (21.1%, 4/19);The most frequent mutations in de novo AML were FLT3-ITD(18.0%, 42/233), NPM1(16.3%, 38/233), DNMT3A(14.9%, 14/94); DNMT3A(P=0.006),IDH2(P=0.004) and NPM1(P=0.002) were statistical difference between MDS and MDS/AML; FLT3-ITD(P=0.001),NPM1(P=0.002),CEBPA(P=0.011) and IDH2(P=0.019) were statistical difference between MDS and de novo AML;There were no siatistical significance (P>0.05) in the frequency of all detected gene mutations between MDS/AML and AML. Conclusion The spectrum of gene mutation of MDS, MDS/AML and primary AML have similarities and heterogeneity.The changes of gene mutations from MDS to MDS/AML and de novo AML not only affect disease outcome and prognosis, but also help to identify MDS/AML and de novo AML.
