CXCL14和EGFR 在胃癌组织中的表达及其临床意义*

Expression and clinical significance of CXCL14and EGFR in human gastric cancer

  • 摘要: 目的:探讨趋化因子CXCL14和表皮生长因子受体(epidermal growth factor receptor ,EGFR)在胃癌中的表达及与临床病理特征间的关系。方法:收集2014年3 月至2015年12月武警后勤学院附属医院手术切除胃癌标本121 例及其癌旁非肿瘤胃黏膜62例和异体非肿瘤胃黏膜60例,采用免疫组织化学法分别检测CXCL14和EGFR 的表达。结果:胃癌组织中CXCL14和EGFR 阳性表达率分别为80.17% 和48.76% ,均显著高于癌旁非肿瘤胃黏膜和异体非肿瘤胃黏膜,差异均具有统计学意义(均P < 0.01);CX?CL14表达与胃癌浸润深度、分化程度和临床分期有关,差异均具有统计学意义(均P < 0.05);EGFR 表达与胃癌分化程度、淋巴结转移和临床分期有关,差异均具有统计学意义(均P < 0.05)。 Spearman 相关分析显示,胃癌中CXCL14的表达与EGFR 呈正相关(r s = 0.195,P < 0.05)。结论:在胃癌中CXCL14异常表达可能与胃癌的发生发展有关,与EGFR 表达呈正相关,推测二者在胃癌发生发展过程中有一定协同作用。

     

    Abstract: Objective:To investigate the expression of C-X-C chemokine ligand-14(CXCL14) and epidermal growth factor receptor (EG -FR) in human gastric cancer and to analyze the relationship of CXCL14with clinicopathological features. Methods:The expression of CXCL 14and EGFR was detected by Immunohistochemical SP method in 121 cases of gastric cancer tissue, 62cases of the adjacent non-tumor gastric mucosa, and 60cases of allogeneic non-tumor gastric mucosa. Results: The positive rates of CXCL 14and EGFR expres -sion were 80. 17% and 48. 76% in gastric cancer, respectively, and both were significantly higher in the adjacent non-tumor gastric mu -cosa and allogeneic non-tumor gastric mucosa. The differences were significant (P<0. 01). Overexpression of CXCL 14was closely corre  lated with the depth of cancer invasion, differentiation, and clinical stage, and the differences were significant ( P<0. 05). Overexpres -sion of EGFR was correlated with cancer differentiation, lymph node metastasis, and clinical stage. The differences were significant ( P< 0. 05). Based on the Spearman correlation analysis, the expression of CXCL 14and EGFR in gastric cancer was positively correlated ( rs=0. 195 , P<0. 05). Conclusion: Abnormal CXCL14expression in gastric cancer may be associated with the occurrence and development of gastric cancer. CXCL 14expression is positively correlated with EGFR expression, suggesting that the two have a synergistic effect in gas-tric cancer development.
