【摘要】 目的:研究原发性肝细胞癌组织中Survivin的表达及其与肝癌细胞的生物学行为及预后的关系。方法:应用免疫组织化学染色对83例肝癌及相应癌旁组织中Survivin蛋白的表达情况进行检测,应用半定量RT-PCR技术对11例肝癌及相应癌旁组织中Survivin mRNA的表达情况进行检测,结合临床病理资料分析。结果:肝癌及癌旁组织中Survivin蛋白的表达率分别为63.9%(53例)和39.6%(21例)。肝癌组织中,41.5%(22例)表达于肝癌细胞核,45.3%(24例)表达于肝癌细胞浆,13.2%(7例)在胞核、胞浆中均有表达。统计学分析表明,Sur-vivin蛋白阳性反应定位于胞核的病例,其肿瘤的包膜侵犯率和转移率更高(P<0.05);且术后生存期<2年的肝癌组中的核表达率显著高于术后生存期≥2年者(P<0.01)。RT-PCR结果显示,11例肝癌组织均表达Survivin mRNA,而癌旁组织只有45.5%(5例)表达。结论:Survivin在肝癌中呈现高表达,其核表达与肝癌的恶性生物学行为及预后密切相关。更多还原

【Abstract】 AIM: To study the expression of Survivin and its relationship to prognosis in human hepatocellular carcinoma(HCC).METHODS: The expression of Survivin protein in 83 cases of HCC and their neighboring noncancerous tissues was detected by immunohistochemistry. The expression of Survivin mRNA in 11 cases of HCC and their neighboring noncancerous tissues was detected by semi-quantitative RT-PCR. RESULTS: Survivin protein expression was detected in 53 of 83 (63.9%) HCC tissues and 21 of 53 (39.6%) corresponding noncancerous tissues. 22 of 53 Survivin-positive HCCs (41.5%) showed punctate nuclear staining in HCC cells, 24 of 53 Survivin-positive HCCs (45.3%) showed cytoplasmic staining in HCC cells and the remaining 7 showed both nuclear and cytoplasmic staining. The positive rates of nuclear Survivin expression in cases of envelope invasion or tumor metastasis were significantly higher than those in cases without envelope invasion or tumor metastasis (P<0.05). The patients with positive nuclear Survivin expression had the higher chance of poor prognosis than those with negative nuclear Survivin expression (P<0.01). Survivin mRNA was detected in all the 11 HCC and 5 of 11 (45.5%) neighboring noncancerous tissues.CONCLUSION: There is a high expression of Survivin in HCC and positive nuclear Survivin may play an important role in malignant biological behavior and prognosis of HCC.更多还原
