摘要
目的:探讨异基因造血干细胞移植(allo-HSCT)后并发肝脏cGVHD患者的危险因素及预后。方法:总结2013年1月至2016年12月期间在本院接受allo-HSCT的147例患者临床资料,回顾性分析患者性别、年龄、移植前疾病状态、HLA相合程度、供者性别、干细胞类型、GVHD预防方案中是否加用ATG、预处理期间肝功能异常、移植前HBsAg、急性GVHD与肝脏cGVHD发生的关系,并分析肝脏cGVHD与患者预后关系。结果:32例患者发生肝脏cGVHD,累积发生率26.4%。单因素分析移植前HBsAg~+及预处理期间肝功能异常均与肝脏cGVHD无明显相关(P>0.05),多因素分析显示,早期出现aGVHD(HR=2.087,P=0.045)是肝脏cGVHD的独立危险因素,加用ATG显著降低肝脏cGVHD的发生率(HR=0.231,P=0.000)。单因素分析发生肝脏cGVHD与未发生组相比患者移植后2年复发率较低(P=0.038)。结论:移植早期出现aGVHD是肝脏cGVHD发生的独立危险因素,ATG可以减少肝脏cGVHD的发生率。肝脏cGVHD患者移植后2年复发率相对低。
Objective: To analyze the risk factors and prognosis of hepatic chronic GVHD after allogeneic hematopoietic stem cell transplantation( allo-HSCT). Methods: The clinical data of 147 patients undergoing allo-HSCT from January 2013 to December 2016 were analyzed,the correlation between recipient age and sex,disease state,matched degree of HLA,donor sex,stem cell sources,ATG in GVHD prophylaxis,liver dysfunction during conditioning period,pre-transplant HBsAg,prior aGVHD and hepatic cGVHD were studied,and the correlation between hepatic cGVHD and prognosis were analysed. Results: Thirty-two patients had hepatic cGVHD,cumulative incidence of 26. 4%. In univariate analysis,pre-transplant HBsAg + and liver dysfunction during conditioning period were not significantly related with hepatic cGVHD( P > 0. 05). In multivariate analysis,prior acute GVHD( HR = 2. 087,P =0. 045) was the independent risk factor for hepatic cGVHD,ATG( HR = 0. 231,P = 0. 000) was significantly related with a lower incidence of hepatic cGVHD. In univariate analysis,patients with hepatic cGVHD had a lower 2 years relapse rate( P = 0. 038). Conclusion: Prior acute GVHD is the independent risk factor for hepatic cGVHD,the ATG can significantly reduce the incidence of hepatic cGVHD. Hepatic cGVHD has been found to relate with a lower 2 years relapse rate.
