摘  要:目的探讨窖蛋白-1在肺腺癌中表达的临床病理意义和预后价值。方法采用免疫组织化学EnVision法检测185例肺腺癌中窖蛋白-1、甲状腺转录因子1(TTF.1)的表达,分析窖蛋白.1表达水平与临床病理参数和预后的关系。结果窖蛋白.1在肺腺癌中阳性率为26.5%(49/185),显著低于正常肺组织(阳性率100%,P〈0.01)。窖蛋白-1表达水平在男性(P=0.004)、吸烟(P=0.006)、肿瘤最大径〉3.5cnl(P=0.048)、实体为主型腺癌(P=0.025)、高危险度(P=0.044)、脉管侵犯(P=0.019)、淋巴结转移(P=0.030)、复发(P=0.021)及高临床分期(P=0.027)的患者中明显高于对照组。窖蛋白-1表达在TTF-1阴性组的阳性率高于‘rrF-1阳性组(P=0.022),且两者表达呈负相关趋势(r=一0。154,P=0.037)。窖蛋白.1阳性表达患者的5年累积生存率(32.7%)显著低于阴性患者(84.8%,P〈0.01),1TrF-1阴性表达患者的5年累积生存率(21.6%)显著低于阳性患者(86.1%,P〈0.01)。单因素生存分析显示,窖蛋白-1与TTF-1表达水平(P〈0.01)、组织学亚型(P=0.002)、危险度分级(P=0.002)、肿瘤最大径(P=0.009)、脉管侵犯(P=0.019)、淋巴结转移(P=0.018)、复发(P=0.032)及临床分期(P=0.024)是患者术后生存期的影响因素,而COX多因素分析显示窖蛋白.1阳性(P=0.043)、TTF—1阴性(P=0.003)及高危险度分级(P=0.028)的肺腺癌患者术后生存时间较短。结论窖蛋白-1表达与肺腺癌组织学亚型及侵袭转移密切相关,对判断组织学起源和评估预后具有重要价值,窖蛋白-1阳性提示预后不良。[Abstract] Objective To study the expression, clinicopathologic correlation and prognostic significance of caveolin-1 in lung adenocarcinomas (LAC). Methods Immunohistochemical study (EnVision method) for caveolin-1 and TTF-1 was carried out in 185 cases of LAC encountered during the period from 2005 to 2010. The correlation between caveolin-1 expression and various clinicopathologic parameters was analyzed statistically. Results The rate of caveolin-1 expression in the 185 eases of LAC was 26. 5% (49/185) and significantly lower than that in normal lung tissue (P 〈 0. 01 ). There was also higher rate of caveolin-1 expression in male patients ( P = 0. 004 ) , smokers ( P = 0. 006 ) , tumors larger than 3.5 cm ( P = 0. 048 ) , predominantly solid tumor subtype ( P = 0. 025 ) , high tumor grade ( P = 0. 044) , tumors with vascular invasion ( P = 0. 019 ) , lymph node metastasis ( P = 0. 030) , recurrence (P = 0. 021 ) and high clinical stage (P = 0. 027 ). The expression level of caveolin-1 in TFF1-negative cases was significantly higher than that in TTFl-positive cases and caveolin-1 expression also negatively correlated with TI'F-1 expression in LAC (r = -0. 154, P = 0. 037 ). The five-year overall survival rate of patients with caveolin-1 positive tumors was lower than that in caveolin-1 negative group (P 〈 0. 01 ). Univariate analysis indicated the expression level of caveolin-1 and TrF-1 ( P 〈 0. 01 ) , histologic subtype ( P = 0. 002 ) , tumor grade ( P = 0. 002 ) , tumor size ( P = 0. 009 ) , vascular invasion ( P = 0. 019) , lymph node metastasis ( P = 0. 018), recurrence (P = 0. 032) and clinical stage (P = 0. 024) correlated with the survival of patients with LAC. COX muhivariate analysis revealed that LAC with caveolin-1 positive expression, TYF-1 negative expression and high tumor grade carried a significantly unfavorable prognosis. Conclusion Caveolin-1 expression correlates with histologic subtype, tumo
