FISH结合组织芯片技术检测不同进展阶段肺癌组织中Survivin mRNA的表达和意义(英文)

目的用荧光原位杂交(fluorescence in situ hybridization,FISH)方法检测肺癌进展组织芯片中Survivin mRNA的表达,并探讨其在肺癌发生、发展中的作用和意义。方法利用FISH方法和组织芯片技术,检测肺原发癌89例,淋巴结转移肺癌12例,肺癌前病变12例和正常肺标本10例中Sur- vivin mRNA的表达情况。结果原发肺癌中有69．7％表达Survivin mRNA,显著高于正常组(P<0．05);癌前病变组Survivin mRNA的表达显著高于正常组 (P<0．05);Survivin mRNA的表达与分化程度、淋巴结转移和临床分期相关(P<0．05)。结论 FISH敏感性强,荧光标记物稳定;组织芯片技术具有高效率、高信息量等优点,在病理学中有很好的应用前景;Survivin mR- NA在肺癌和癌前病变组织中高表达,与进展程度和恶性行为相关,对肺癌的发生、发展起促进作用,为早期诊断、预后估计和治疗提供一定的依据。

Expression and Significance of Survivin mRNA in Lung Cancer of Different Progression Stages by FISH and Tissue Microarray Technology*

Objective: To investigate the expression of Survivin mRNA in lung cancer progression tissue microarray by FISH (fluorescence in situ hybridization) method and determine its role and significance in lung cancer genesis and progress. Methods: The expression of Survivin mRNA was detected by FISH method and tissue microarray technology. 89 cases of primary lung cancer, 12 cases of lymph node metastasis of lung cancer, 12 cases of precancerous lesion and 10 cases of normal lung tissue were examined. Results: 69.7% of primary lung cancer express Survivin mRNA; the positive ratio of primary lung cancer and precancerous lesion were both significantly higher than that of normal lung tissue (P<0.05); the expression of Survivin mRNA was related to the differentiation degree, lymph node metastasis and clinical stages (P<0.05). Conclusion: FISH has good sensitivity and stability. Tissue microarray technology has many advantages, such as high efficiency, high throughput, etc; it may have good prospect in pathology. Survivin mRNA was highly expressed in lung cancer and precancerous lesion; it was related to the progress and malignant behavior; it may play a promotion role in lung cancer genesis and progress and offer basis to early diagnosis, prognosis estimate and treatment.
