JAK2、MPL和CALR基因突变在中国原发性骨髓纤维化患者中的预后意义
目的评价JAK2、MPL和CALR基因突变在中国原发性骨髓纤维化(PMF)患者中的预后意义。方法回顾性分析402例PMF患者的临床资料及JAK2、MPL和CALR基因突变,应用Kaplan—Meier、Log.rank和Cox回归模型进行相关预后因素分析。结果402例PMF患者中男209例,女193例,中位年龄55(15~89)岁。JAKV617F基因突变189例(47.0%),MPLW515基因突变13例(3.2%),CALR基因突变81例(20.1%)[1型突变30例(37.0%),2型突变48例(59.3%),少见型突变3例(3.7%)],119例(29.6%)未检测到JAK2、MPL和...

Summary: | 目的评价JAK2、MPL和CALR基因突变在中国原发性骨髓纤维化(PMF)患者中的预后意义。方法回顾性分析402例PMF患者的临床资料及JAK2、MPL和CALR基因突变,应用Kaplan—Meier、Log.rank和Cox回归模型进行相关预后因素分析。结果402例PMF患者中男209例,女193例,中位年龄55(15~89)岁。JAKV617F基因突变189例(47.0%),MPLW515基因突变13例(3.2%),CALR基因突变81例(20.1%)[1型突变30例(37.0%),2型突变48例(59.3%),少见型突变3例(3.7%)],119例(29.6%)未检测到JAK2、MPL和CALR基因突变。单因素分析显示,2型CALR突变或未检测到JAK2、MPL和CALR基因突变的患者中位生存期(74个月)短于检测到JAK2、MPL或1型及少见型CALR基因突变的患者(168个月)[HR=2.990(95%C11.935-4.619),P〈0.001]。因此,将基因突变类型分为预后不良组(2型CALR突变和未检测到JAK2、MPL和CALR基因突变)和预后良好组(JAKV617F、MPLW515、1型及少见型CALR基因突变)。经多因素分析提出了中国PMF患者的动态国际预后积分系统(DIPSS—Chinese)分子预后积分系统,各参数赋值如下:DIPSS.Chinese低危组0分,中危组1分,高危组2分,2型CALR突变或未检测到JAK2、MPL和CALR基因突变积1分。402例患者中,低危组(0分)132例(32.8%),中危-1组(1分)143例(35.6%),中危.2组(2分)106例(26.4%),高危组(3分)21例(5.2%)。低危组中位生存时间未达到,中危-1组为156(95%C1117~194)个月,中危.2组为60(95%CI28~91)个月,高危组为22(95%CI10~33)个月,总生存差异具有统计学意义(P〈0.001)。DIPSS.Chinese分子预后积分系统较DIPSS—Chinese有更准确的预测能力(-2log似然比分别为855.6和869.7,P=0.005)。结论在中国PMF患者中,2型CALR突变和未检测到JAK2、MPL和CALR突变是独立的不良预后因素,DIPSS—Chinese分子预后积分系统有更好的预测价值。 |

Methods Four hundred and two Chinese patients with PMF were retrospectively analyzed. The Kaplan-Meier method, the Log-rank test, the likelihood ratio test and the Cox proportional hazards regression model were used to evaluate the prognostic scoring system. Results This cohort of patients included 209 males and 193 females with a median age of 55 years (range: 15-89). JAK2V617F mutations were detected in 189 subjects (47.0%), MPLW515 mutations in 13 (3.2%) and CALR mutations in 8 |
