摘要
目的探讨CXC趋化凶子受体4(CXCR4)和生存素(Survivin)蛋白在非小细胞肺癌中的表达及其临床意义。方法应用免疫组织化学法检测64例肺癌组织标本及癌旁组织CXCR4和Survivin的表达,分析其表达与临床病理参数及预后的关系。结果64例肺癌组织中有41例CXCR4蛋白阳性表达干丌43例Survivin蛋白阳性表达,阳性表达率分别为64.1%和67.2%,正常肺组织呈阴性表达(P〈0.01);CXCR4和Survivin蛋白表达与TNM分期、淋巴结转移和组织分化程度有关(P〈0.05);肺癌中CXCR4和Survivin蛋白表达呈正相关(r=0.448P〈0.05)。结论CXCR4和Survivin蛋白在肺癌中高表达,两者在肺癌的发展中相互促进。
Objective To investigate the expression of CXC chemokine receptor -4 (CXCR4) and Survivin in non - small lung cancer and the mechanism. Methods Immunohistochemical streptavidin - pero- sidase technique was used to detect the expression of CXCR4 and Survivin in 64 cases of non - small lung cancer tissues. Subsequently, the associations between CXCR4 expression, Survivin expression, CXCR4/ Sarvivin coexpression and clinicopathologic factors were assessed, and survival analyses were peribrmed. Results In total, 41 (64. 1%) patients expressed CXCR4, 43 (67.2%) expressed Survivin, and 34 ( 82.9% ) coexpressed CXCR4 and Survivin. Significant association between CXCR4 and Survivin expres- sion was observed ( r = 0. 448 ) in non - small lung cancer tissues. The expression of CXCR4 was correlated wilh tmnor differentiation, TNM stage and lymph node metastasis (P 〈 0. 05 ), but not with histological types, gender and age (P 〉 0. 05 ). The positive rate of Survivin was correlated with differentiation, clinical staging and lymph node metastasis (P 〈 0. 05 ) , but not with gender, age and histological types (P 〉 0. 05 ). Conclusion The high expression of CXCR - 4 and Survivin may contribute to metastasis, invasion and lymph node metastasis of non - small lung cancer.
