Abstract

目的评估修订版国际血栓预测模型(IPSET)在中国原发性血小板增多症(ET)患者中的应用价值,探索适用于中国ET患者的血栓预测模型。方法对1982年3月1日至2012年4月30日期间诊治的746例成人ET患者的病历资料进行回顾性分析。结果全部746例患者中,男305例,女441例,诊断时中位年龄52(18~87)岁。采用修订版IPSET将患者分组,其中极低危组271例(36.3%)、低危组223例(29.9%)、中危组63例(8.4%)、高危组189例(25.3%),四组的无血栓生存差异有统计学意义(χ2=72.301,P<0.001)。修订版IPSET在原版IPSET低危组中区分出36例中危患者,在原版IPSET中危组中区分出19例高危患者,在原版IPSET高危组中区分出51例低危患者,避免了部分患者的治疗不足或过度。修订版IPSET低危组中有心血管危险因素(CVF)者的血栓发生率显著高于无CVF者[16.3%(8/49)对5.2%(9/174),χ2=5.264,P=0.022],而与中危组相当[16.3%(8/49)对14.3%(9/63),χ2=0.089,P=0.765]。因此,在修订版IPSET的基础上,低危组中伴CVF者被划分至中危组,即为适于中国ET患者的修订版IPSET,此模型能区分出更多的血栓患者。结论修订版IPSET在血栓预测方面优于原版IPSET,将修订版IPSET优化后得到了更适于中国ET患者的修订版IPSET,为中国ET患者的分层治疗提供了依据。
