目的:研究Survivin蛋白在非小細(xì)胞肺癌(NSCLC)中表達(dá)的臨床意義。方法:運(yùn)用免疫組化(IHC)方法檢測(cè)51例NSCLC組織、21例癌旁組織和11例良性肺病變組織中Survivin的表達(dá),并采用SPSS13.0軟件進(jìn)行統(tǒng)計(jì)分析。結(jié)果:Survivin在胞漿和/或胞核均有表達(dá),其在NSCLC、癌旁和良性肺病變組織中的陽(yáng)性率之間存在顯著統(tǒng)計(jì)學(xué)差異(Plt;0.001),腫瘤組表達(dá)(76.5%,39/51)高于癌旁組織(19.0%,4/21)(P=0.000)。Survivin表達(dá)與分化程度有關(guān)(Ρlt;0.05),其生存曲線及復(fù)發(fā)轉(zhuǎn)移風(fēng)險(xiǎn)曲線均沒有意義(Ρ>0.05)。多因素COX回歸分析提示臨床分期和復(fù)發(fā)轉(zhuǎn)移狀態(tài)為影響生存的因素。結(jié)論:Survivin可能與NSCLC的發(fā)生發(fā)展相關(guān),還不能支持它作為判斷預(yù)后和復(fù)發(fā)轉(zhuǎn)移的指標(biāo)。

Survivin, a member of inhibitor of apoptosis protein (IAP) family, is one of the most powerful factors in inhibiting apoptosis up to now. This study is to explore the value of ERCC1 and Survivin in predicting the sensitivity of non-small cell lung cancer (NSCLC) to platinum-based chemotherapy and the interrelationship between the two markers. Methods From January 2001 to June 2002, expressions of ERCC1 and Survivin of 51 advanced NSCLC patients (Ⅲ B or IV) were tested through immunohistochemistry. The patients were treated with at least 2 cycles of platinum-based chemotherapy. The curative effect was evaluated later, and the relationship among detected data, curative effect of chemotherapy and patients′ clinical parameters were analyzed with SPSS 13.0 software. Results The positive expression rates of ERCC1 and Survivin in NSCLC tissues were 58.8 % (30/51) and 76.5 % (39/51), respectively. The effective rate of chemotherapy and 5-year survival rate for the negative group of ERCC1 were significantly higher than those for the positive group (Plt;0.05). The results for Survivin were similar to those for ERCC1, but there was no statistical significance (Pgt;0.05). We also found there was no relationship between ERCC1 and Survivin by Spearman′s correlation analysis (rs=-0.088, P=0.537). Conclusion ERCC1 and Survivin may be correlated with the development of NSCLC, and ERCC1 may be related to curative effect and prognosis of NSCLC. There was probably no mechanism of coordination or regulation in multi-drug resistance between ERCC1 and Survivin.
