Abstract

目的探讨极高危原发性轻链型淀粉样变(pAL)患者的临床特征及其预后。方法回顾性分析2009年1月至2016年2月在北京协和医院确诊的205例pAL患者的临床资料,将梅奥2004分期Ⅲb期或梅奥2012分期4期的患者定义为极高危患者。结果34例(16.6%)为极高危pAL患者,中位年龄57(20~84)岁,男性22例(64.7%)。所有患者均有心脏受累,15例(44.1%)患者的受累脏器≥ 3个。27例(81.8%)患者的心功能分级为3~4级,中位血清肌钙蛋白I为0.25(0.08~1.23)µg/L,中位血清N末端B型利钠肽前体为11 733(1 892~103 277)ng/L,中位血清游离轻链差值为403.0(18.1~1 911.6)mg/L,8例(24.2%)患者的骨髓浆细胞比例≥0.100。16例(47.1%)患者采用硼替佐米为主的化疗方案,总体血液学缓解率为58.3%。中位随诊27(1~40)个月,14例(41.2%)患者在诊断后3个月内死亡,中位生存时间仅为4个月。3、6、12和24个月的预期生存率分别为51.3%、44.0%、35.2%和29.6%。一线化疗后获得血液学缓解、未获得血液学缓解以及姑息治疗的患者1年预计存活率分别为90.9%、11.1%及0(P<0.001)。结论极高危pAL患者的预后极差,早期病死率高,获得血液学缓解的pAL患者有着明显更好的预后。
