摘要:

背景:肿瘤干细胞标志物CD133在非小细胞肺癌发生、发展过程中的作用存在争议。
目的:系统评价有关非小细胞肺癌组织中CD133表达及临床意义的病例对照研究。
方法:计算机检索PubMed、EMBASE、Web of Science、中国生物医学文献数据库(CBM)、中文科技期刊全文数据库(VIP)、中国期刊全文数据库(CNKI)及万方数据库,并辅以文献追溯的方法,收集国内外发表的相关病例对照研究,检索时间均从建库至2012年9月。两位研究者按纳入排除标准筛选文献并评价纳入研究质量,应用RevMan5.1软件进行Meta分析。
结果与结论:共纳入10个病例对照研究,包含非小细胞肺癌组织808例。Meta分析结果显示:在CD133表达方面,非小细胞肺癌组织比癌旁组织或正常组织高[OR=8.15,95%CI(4.61, 14.41),P < 0.000 01],有淋巴结转移的非小细胞肺癌组织比无淋巴结转移的高[OR=1.83,95%CI(1.06, 3.17),P=0.03],中低分化的非小细胞肺癌组织比高分化的高[OR = 2.09,95%CI(1.42, 3.08),P=0.000 2];非小细胞肺癌组织病理分级Ⅰ级和临床Ⅱ-Ⅲ级CD133表达的差异无显著性意义[OR=1.06,95%CI (0.66,1.70),P=0.81]。现有研究表明,CD133在非小细胞肺癌发生、发展过程中可能起重要作用,但其能否作为非小细胞肺癌诊断及预后的可靠指标尚不确定,需要进行更多设计严谨、细致的高质量流行病学研究来进一步证实。

Abstract:

BACKGROUND: Argument exists about the role of tumor stem cell marker CD133 in the development of non-small cell lung cancer.
OBJECTIVE: To systemically evaluate the case-control studies addressing the CD133 expression and clinical significance in non-small cell lung cancer.
METHODS: A computer-based retrieval of PubMed, EMBASE, Web of Science, CBM, VIP, CNKI and Wanfang Database was performed from their establishment to September 2012 for case-control studies investigating the CD133 expression and clinical significance in non-small cell lung cancer. After evaluating methodological quality of studies met the inclusion criteria, we analyzed the data with meta analysis using RevMan 5.1 software.
RESULTS AND CONCLUSION: Ten case-control studies were identified, involving 808 cases with non-small cell lung cancer. Meta analysis results showed that, the positive rate of CD133 expression in non-small cell lung cancer was significantly higher than that in normal lung tissues [odd ratio (OR)=8.15, 95% confidence interval (CI) (4.61, 14.41), P < 0.000 01], and also higher in non-small cell lung cancer tissue with lymph node metastasis than that with non-lymph node metastasis [OR = 1.83, 95%CI (1.06, 3.17), P = 0.03], as well as higher in non-small cell lung cancer tissue with low and moderate differentiation than that with high differentiation [OR=2.09, 95%CI(1.42, 3.08), P=0.000 2]. There was no significant difference in the CD133 expression between pathologic grading I vs. pathologic grading Ⅱ-Ⅲ non-small cell lung cancer tissue [OR = 1.06, 95%CI (0.66, 1.70), P=0.81]. Experimental findings indicate that, CD133 plays a crucial role in the development of non-small cell lung cancer. However, it is still unclear whether CD133 could be regarded a marker to diagnose and predict non-small cell lung cancer, which needs more high-quality case-control studies to explore the question clearly.
