摘要:
目的研究一种潜在的肿瘤标记物CHCHD2在非小细胞肺癌(NSCLC)患者肿瘤组织和癌旁组织中的表达情况。方法采 用免疫组化法检测60例NSCLC患者肿瘤组织及35例癌旁组织中CHCHD2蛋白的定位与表达,分析其与肺癌患者临床病理参 数、总生存(OS)之间的关系。运用Oncomine数据库分析CHCHD2mRNA在非小细胞肺癌中表达水平。结果免疫组化结果显 示CHCHD2在NSCLC中的阳性表达率(75.0%)明显高于癌旁组织(17.1%),且与淋巴结转移、TNM分期、肿瘤分化程度密切相 关,而与性别、年龄、组织学分型无关;Oncomine数据库分析结果表明与正常对照组相比,CHCHD2 mRNA在非小细胞肺癌中 高表达(P<0.05);Kaplan-Meier生存曲线分析表明,在NSCLC中CHCHD2蛋白阳性表达组患者术后总的生存时间明显低于阴 性组患者,log-rank分析其差异有统计学意义。结论CHCHD2在NSCLC中高表达,可能作为一种潜在的肿瘤标志物参与了 NSCLC的发生、发展,并促进其侵袭和转移,有望作为NSCLC早期诊断及判断不良预后的指标。
Abstract:
Objective To investigate the expression of CHCHD2, a potential tumor marker, in tumor and adjacent tissues from patients with non-small cell lung cancer (NSCLC). Methods Immunohistochemistry was used to detect the expression and location of CHCHD2 in the tumor tissues from 60 patients with NSCLC and 35 adjacent tissues to analyze the correlation of CHCHD2 expression with the clinicopathological variables and overall survival of the patients. The expression profile of CHCHD2 mRNA in NSCLC was analyzed using Oncomine database. Results The positivity rate of CHCHD2 was significantly higher in the tumor tissues than in adjacent tissues in patients with NSCLC (75.0% vs 17.1%). CHCHD2 positivity in the tumor tissues was associated with lymph node metastasis, pathological TNM stage, and tumor grades but not with age, gender, or histological type of the tumors. Analysis using Oncomine database showed that CHCHD2 mRNA was expressed at significantly higher levels in NSCLC than in normal control group (P<0.05). Kaplan-Meier survival analysis showed that NSCLC patients with a positive expression of CHCHD2 had a significantly shorter overall survival time than those negative for CHCHD2 (P<0.05). Conclusion As a potential tumor marker, CHCHD2 over-expression plays a role in the occurrence and progression of NSCLC and promotes tumor invasion and metastasis, and can potentially serve as an indicator for early diagnosis and prognostic evaluation of NSCLC.
