摘　　要：目的探讨造血干细胞移植共患病指数（HCT-CI）对异基因造血干细胞移植（allo-HSCT）患者移植后非复发死亡率（NRM）及总生存（OS）率的预测作用。方法选取2003年7月至2010年11月allo—HSCT患者161例纳入研究队列随访并总结临床资料，多因素分析HCT-CI、患者年龄、性别、预处理方案、移植前疾病状态、移植方式、HLA配型对NRM及OS率的影响。分析在不同移植前疾病状态下，HCT-CI评分对OS率及NRM的预测作用。结果161例allo-HSCT患者3年OS率及NRM分别为61．4％及26．4％。HCT-CI评分0分、1-2分及I〉3分组患者的3年NRM分别为14．9％、24．5％、52．7％，3年OS率分别为68．9％、64．6％、34．7％。组间比较显示，HCT-CI评分I〉3分和0分组患者的3年NRM及OS率差异有统计学意义（P值均〈0．01）。COX回归模型分析显示，移植前疾病状态高危、HCT-CI评分〉13为影响OS率及NRM的独立危险因素（相对危险度分别为3．53和3．35，3．77和6．85，P值均〈0．01）。在移植前疾病状态为低危的101例患者中，HCT-CI评分为0分、1-2分和I〉3分组患者的3年NRM及OS率差异有统计学意义（P值均〈0．01）；而在高危组的60例患者中，不同HCT-CI评分组间OS率及NRM的差异无统计学意义（P=0．252及0．347）。结论HCT-CI评分及移植前疾病状态分层是影响allo-HSCT后NRM和OS率的独立危险因素。在移植前疾病状态低危组，HCT-CI评分对allo-HSCT移植后的NRM及OS率具有预测作用；在移植前疾病状态高危组，HCT-CI评分对NRM及OS率无预测作用。Objective To study the prognostic implications of hematopoietic cell transplantationspecific comorbidity index （HCT-CI） on non-relapse mortality （NRM） and overall survival （OS） in patients underwent allogeneic hematopoietic stem cell transplantation （allo-HSCT）. Methods Clinical data of 161 cases received allo-HSCT from July 2003 to November 2010 were analyzed retrospectively. The prognostic significance of HCT-CI, age, sex, conditioning regimens, disease status before transplantation, graft source and the degree of HLA matches for NRM and OS was conducted by COX regression model. The prognostic impact of HCT-CI on NRM and OS was performed in all patients under different disease status before transplantation. Results Of the 161 cases with allo-HSCT, 3-year NRM and OS were 26.4% and 61.4% respectively. NRM at 3 years in patients with HCT-CI score 0, 1-2 and ≥3 were 14.9% , 24.5% and 52.7% respectively. And OS at 3 years were 68.9% , 64.6% and 34.7% respectively. There were significant differences between HCT-CI score 0 and≥3 groups for NRM and OS （P〈0.01）. High-risk disease status before transplantation （NRM： RR=3.35, P〈0.01; OS： RR=3.53, P〈 0.01） and HCT-CI score≥3 （NRM： RR=6.85, P〈0.01; OS： RR=3.77, P〈0.01） were independent risk factors by COX regression model. In the subgroup analysis according to disease status, high score of HCT- CI was associated with poor OS （P〈0.01） and high NRM （P〈0.01） in patients with low-risk, but not in those with high-risk disease status. Conclusions HCT-CI score and disease status before transplantation are independent risk factors for patients received allo-HSCT. HCT-CI score have prognostic implication for NRM and OS in patients with low-risk disease status, but not in high-risk group.
