摘要 目的: 研究 EGFR (epidermal growth factor receptor)、 HER2 ( human epidermalgrowth factor receptor-2) 及 CXCR4 (chemokine
(C-X-C motif) receptor 4)在 NSCLC 中的表达, 分析它们与 NSCLC 临床病理特征的的关系。 方法: 选择我科 2009 年 7 月 -2012 年
12 月收治的 75 例非小细胞肺癌 (NSCLC ) 患者为研究对象, 支气管镜活检得到 NSCLC 肿瘤组织标本,免疫组织化学技术分别检
测 EGFR、 HER2、 CXCR4 在 NSCLC 组织中的表达,并分析 EGFR、 HER2、 CXCR4 的表达与 NSCLC 患者临床病理指标和生存期
的相关性。 结果: EGFR、 HER2 及 CXCR4 在 NSCLC 中的表达与患者淋巴转移及远处转移有关 (P<0.05 )。 EGFR、 HER2 及 CXCR4
在 NSCLC 中的表达均呈正相关, EGFR 与 HER2, EGFR 与 CXCR4, HER2 与 CXCR4 的相关系数分别为 r=0.296 ( P<0.01 ), r=0.
578 ( P<0.01 ), r=0.426 ( P<0.01 )。3 种基因表达越多, 患者中位生存时间越短 (P<0.05 )。结论: EGFR、 HER2 及 CXCR4 与 NSCLC
的发生发展关系密切, 针对性的多个靶向抑制, 可更好发挥抑癌作用。根据三者不同的表达情况初步筛选出针对靶向治疗的单一
或联合靶点, 有助于为 NSCLC 患者提供个体化的治疗方案。为进一步治疗提供依据。 |

ABSTRACT Objective:To investigate the expression of EGFR(epidermal growth factor receptor), HER2( human Epidermal growth
factor receptor-2) and CXCR4 (chemokine (C-X-C motif) receptor 4) in NSCLC and analyze their relationship with clinicopathological
features of Non-small cell lung cancer (NSCLC). Methods:75 cases of NSCLC admitted in our hospital from July 2009 to December
2012 were selected, and the expressions of EGFR, HER2 and CXCR4 in NSCLC tissues from bronchoscopic biopsy were detected by
immunohistochemical technique. The correlation between EGFR, HER2 and CXCR4 expression and clinicopathological features as well
as survival was analyzed. Results:The positive EGFR, HER2 and CXCR4 expression in NSCLC was significantly correlated with lymph
node metastasis and distant metastasis (P<0.05 ) . The correlation of EGFR, HER2 and CXCR4 expression were positively. The
correlation coefficient of EGFR, HER2 and CXCR4 respectively was r=0.296 (P<0.01), r=0.578 (P<0.01), r=0.426 (P<0.01). Survival
period of EGFR, HER2 and CXCR4 in positive cases were significantly shorter than negative cases; and the more positive expression, the
shorter survival time (P<0.05). Conclusion:Upregulation of the EGFR, HER2 and CXCR4 expression was closely related with NSCLC
metastasis and prognosis. These three proteins which was inhibited may play a better suppressor role. Under the different expression of
the three proteins can screeed a single or combinated therapeutic target, which is benefit for NSCLC patients to provide individualized
therapy and the further treatment basis. |
