摘 要:目的评价抗胸腺细胞球蛋白(ATG)/抗淋巴细胞球蛋白(ALG)治疗重型再生障碍性贫血(SAA)患者的近期疗效及长期生存情况。方法分析1982年12月至2011年6月接受ATG/ALG治疗的345例SAA患者3个月及6个月疗效,长期随访并应用Kaplan—Meier法分析其5年总生存(0s)率。结果345例患者中非极重型AA(mSAA)184例,极重型AA(VSAA)161例。中位随访时间为44.0(0.5~244.0)个月。本组患者3个月及6个月总有效率分别为29.9%及45.4%,mSAA患者3个月及6个月总有效率分别为39.2%和55.6%,显著高于VSAA患者的19.6%和34.0%(P值均〈0.01)。不同种属来源的ATG/ALG治疗SAA患者疗效间差异无统计学意义,兔源ATG中,德国Fresenius制剂(rATG—F)组3个月(10.6%)和6个月(25.5%)总有效率显著低于法国Sangstat制剂(rATG—S)组(36.6%和56.6%)(P值均〈0.01)。Kaplan—Meier法估计所有患者5年0s率为61.7%(95%CI55.4%-68.0%),其中mSAA患者5年0s率为71.0%(95%CI62.9%-79.1%),显著高于VSAA患者的50.4%(95%C140.1%-60.7%)(P〈0.01)。2007年后实施治疗的VSAA患者5年0s率为73.7%(95%CI52.2%~95.2%),与mSAA患者的89.7%(95%C179.5%~99.9%)比较差异无统计学意义(P=0.240)。接受ATG/ALG联合环孢素(CsA)治疗的患者5年0s率为64.8%(95%CI57.9%-71.7%),显著高于单用ATG/ALG治疗者[32.6%(95%CI15.7%。49.5%)](P〈0.01)。加用重组人G—CSF(rhG—CSF)并不能提高患者5年0s率。rATG—S组患者5年0s率为66.1%(95%c,55.8%~76.4%),显著高于rATG-F组患者[46.6%(95%C135.9%~57.3%)](P〈0.01)。结论①mSAA患者近期及远期疗效均优于VSAA患者,2007年后实施治疗VSAA患者长期生存接近mSAA患者;②rATG—S近期及远期疗�Objective To assess the short term curative efficacy and long-term survival outcomes of severe aplastic anemia patients following antithymocyte globulin/lymphoglobulin (ATG/ALG) with or without cyclosporine (CsA). Methods A total of 345 cases hospitalized in our hospital between December 1982 and June 2011 were enrolled into this study. We assessed the response rates 3 and 6 months after ATG/ALG, and estimated the overall survival (OS) by Kaplan-Meier method for this cohort of patients. Results The cohort of 345 patients was routinely followed-up with a median follow-up of 44.0 ( range, 0.5 - 244.0) months. The response rates at 3 and 6 months were 29.9% and 45.4%, respectively. The differences in response rates at both 3 (39.2% vs 19.6%, P 〈 0.01) and 6 months (55.6% vs 34.0%, P 〈 0.01 ) between 184 non-se- vere aplastic anemia (mSAA) and 161 very severe aplastic anemia(VSAA) were statistically significant. The response rates among the different ATG preparations were comparative; but 3-( 10. 6% ) and 6-month(25.5%) responses produced by rATG-Fresenius were significantly inferior to those by rATG-Sangstat (36.6% and 56.6%, respectively) (all P 〈0.01). The 5-year OS was 61.7% (95% CI 55.4% - 68.0% ) for the entire cohort of patients, and 5-year OS for mSAA patients [71.0% (95% CI 62.9% - 79.1% ) ] was superior to that of VSAA patients [ 50.4% (95% CI 40.1% -60.7% ), P 〈 0.01 ] ; but for the patients treated from 2007, the difference of OS in the last 5 years between VSAA and mSAA was not sig- nificant [73.7% (95% C152.2%-95.2%) vs 89.7% (95% C179.5% -99.9%); P=0.24]. Our study also confirmed the superiority of ATG/ALG + CsA regimen [64.8% (95% CI 57.9% -71.7% ) ] over ATG/ALG alone [32.6% (95% CI 15.7% -49.5% ) ~ with regard to 5-year OS (P 〈0.01 ) ; but the addition of recombinant human granulocyte colony-stimulating factor (rhG-CSF) to ATG/ALG had no benefit in terms of OS. rATG-S produced significantly better 5-year
