摘 要:目的:探讨存活素和人类白细胞抗原I类分子( HLA-Ⅰ)在肾透明细胞癌( CCRCC)组织中的表达及其与CCRCC患者预后的关系。方法应用免疫组化方法检测2006年2月至2010年2月90例CCRCC组织及其中10例癌旁正常肾组织中存活素和HLA-Ⅰ的表达情况,应用单因素及多因素分析存活素和HLA-Ⅰ与CCRCC患者年龄、性别、分级、分期、淋巴结情况等临床特征以及与预后的关系。结果 CCRCC 组织中存活素的表达阳性率为82.2%(74/90),HLA-Ⅰ表达下调率为67.8%(61/90),存活素阳性率与肿瘤分级(P=0.016)、分期(P=0.000)及淋巴结转移(P=0.001)相关,而HLA-Ⅰ的表达下调率与患者年龄、性别以及肿瘤分级、分期和淋巴结转移均无关( P>00.5)。存活素表达阴性者的无瘤生存率(25.0%,4/16)高于表达阳性者(52.7%,39/74),差异有统计学意义(P=0.037);HLA-Ⅰ表达正常者的无瘤生存率(27.6%,8/29)高于表达下调者(60.7%,37/61),差异有统计学意义( P=0.020)。单因素及多因素分析结果表明存活素(P =0.033)、HLA-Ⅰ( P=0.026)及两者结合(P=0.014)可作为预测CCRCC患者预后的重要指标。结论存活素阳性表达及HLA-Ⅰ表达下调对预测CCRCC患者无瘤生存期及总生存期有重要意义。Objective To investigate the expression of survivin/Human leukocyte antigen class I ( HLA-Ⅰ) proteins and its physiological significance in clear cell renal cell carcinoma ( CCRCC ) . Methods Immunohistochemistry was used to analyze survivin/HLA-Ⅰ protein expression in 90 cases of CCRCC and 10 normal tissues to study relationships with clinical symptoms and disease prognosis . Resutl s The level of survivin protein expression was found to be significantly higher in CCRCC tissues 82.2%( 74/90) than in normal tissues( 0/10).However, the relative amount of HLA-Ⅰprotein in colorectal cancer tis-sue was also found to be significantly lower 67.8%(61/90) than in normal tissues 90%(9/10).Survivin expression was associated with tumor grade , stage,and lymph node metastasis ( P=0.000, P=0.016, and P=0.001, respectively ) .Conversely , lost HLA-Ⅰexpression did not have any associations with clinicopath-ological data (P〈0.05).Survivin negative patients (25.0%, 4/16) had a higher tumor-free survival rate than patients (52.7%, 39/74)with survivin expression (P=0.037).Patients (27.6%, 8/29) with normal HLA-Ⅰlevels had a higher tumor-free survival rate than those ( 60.7%, 37/61) with reduced HLA-Ⅰlev-els (P=0.020).The univariate and multivariate analyses indicated that expression of survivin and HLA indi -vidually and in combination were independent predictors for CCRCC patient survival . Conclusions Over-expression of survivin but reduced HLA-Ⅰ expression is associated with CCRCC development and progres-sion.
