57例CEBPA基因突变患者占同期所有353例AML患者的16.1%,其中bZIP区域框内突变(CEBPA-bZIPinf)28例,其余CEBPA基因突变(CEBPA-other)29例。与CEBPA-other患者相比,CEBPA-bZIPinf患者更年轻(54岁对64岁,P=0.010),原发性AML更常见(P=0.001),骨髓原始细胞比例更高(68.0%对36.3%,P=0.001)。CEBPA-bZIPinf及CEBPA-other患者分别有24例和19例接受化疗,CEBPA-bZIPinf患者的1个疗程完全缓解率显著高于CEBPA-other(87.5%对47.4%,P=0.010)及CEBPA野生型(87.5%对50.3%,P=0.002)患者。中位随访11个月,CEBPA-bZIPinf患者的中位总生存期明显长于CEBPA野生型患者(未达到对22.1个月,P=0.012)。.
