CD147、NF-κB在食管鳞状细胞癌组织中的表达及意义

The significance and expression of CD147 and NF-κB in esophageal squamous cell carcinoma

目的 研究基质金属蛋白酶刺激因子（CD147）、核转录因子-κB[NF-κB（p65）]在食管鳞状细胞癌组织中的表达及其在食管鳞癌侵袭转移的作用及可能机制.方法 应用免疫组织化学方法检测40例食管鳞癌患者癌组织及其癌旁正常对照组织CD147、NF-κB的表达.结果 CD147、NF-κB在食管鳞癌表达阳性率为77.5%、87.5%,在癌旁正常对照组为25%、42.5%,2组差异有统计学意义（P＜0.05）;CD147在早期和中晚期食管癌表达阳性率为33.3%、90.3%,在NF-κB为55.6%、96.8%,2组差异均有统计学意义（P＜0.05）;CD147在食管鳞癌无转移和转移组表达阳性率为28.6%、87.9%,在NF-κB为42.9%、97%,2组差异均有统计学意义（P＜0.05）.结论 CD147、NF-κB在食管鳞癌组织表达增高,与肿瘤的浸润、转移相关,它们可能是通过共同的作用途径来实现的.

Objective To investigate the expression of extracellular matrix metalloproteinase inducer （CD147）, nuclear factor kappa B （NF-κB） in esophageal squamous cell carcinoma tissue and probe their relationship to invasion and metastasis of esophageal carcinoma. Methods Immunochemical staining was performed to detect the expression of CD147 and NF-κB protein in 40 cases of esophageal carcinoma tissues and 40 cases of normal control. Results The positive rate of CD147 and NF-κB in esophageal carcinoma tissues and in adjacent noncancerous tissues were 77.5%/87.5% Vs 25%/42. 5%, P〈0.05.The positive rate of their prophase and metaphase-advanced stage esophageal carcinoma tissues were 33.3%/90.3% Vs 55.6%/96.8%, P〈0.05..The positive rate of non-metastatic and metastatic esophageal carcinoma tissues were 28.6%/87.9% Vs 42.9%/97%, P〈0.05.Conclusions Our results suggested that the increased expression of CD147 and NF-κB contributed to tumor angiogenesis in esophageal squamous cell carcinoma, which might be through the common pathway.
