sema4c在喉鳞状细胞癌组织中的表达及意义
Keywords: 喉鳞状细胞癌,脑信号蛋白4c,微小染色体维持蛋白2,免疫组化,微淋巴管密度
Abstract:
?目的:探讨脑信号蛋白4c(sema4c)在喉鳞状细胞癌组织中的表达及意义。方法:采用免疫组化envision二步法检测82例喉鳞状细胞癌及癌旁正常喉黏膜组织中sema4c和微小染色体维持蛋白2(mcm2)蛋白的表达水平,用d2-40标记淋巴管,计数微淋巴管密度(lmvd),分析三者的表达水平变化与临床病理指标的关系。结果:sema4c、mcm2蛋白在喉鳞状细胞癌组织中的阳性率分别为60%(49/82)及98%(80/82),均显著高于癌旁正常喉黏膜组织(p<0.01),lmvd在癌及癌旁喉黏膜中的差别无统计学意义(p=0.077);sema4c、mcm2的表达水平与颈部淋巴结转移有关,与年龄及肿瘤t分级无显著相关。sema4c、mcm2蛋白表达水平和lmvd,两两间均呈正相关关系(p<均0.05)。结论:sema4c的异常高表达与喉鳞状细胞癌的发生发展、转移及预后有关,提示sema4c有可能成为判断喉鳞状细胞癌生物学行为及预后指标。
