Tissue microarray (TMA) is a recently implemented, high-throughput technology for the analysis of molecular markers in oncology. This research tool permits the rapid assessment of a biomarker in thousands of tumor samples, using commonly available laboratory assays such as immunohistochemistry and in situ hybridization. Although introduced less than a decade ago, TMA has proven to be invaluable in the study of tumor biology, the development of diagnostic tests, and the investigation of oncologic biomarkers. This review describes the impact of TMA-based research in clinical oncology and its potential future applications. Technical aspects of TMA construction and the advantages and disadvantages inherent to this technology are also discussed.
组织微阵列(TMA)是一种最近应用的高通量技术,用于肿瘤学中分子标志物的分析。这种研究工具能够通过免疫组织化学和原位杂交等常用实验室检测方法,对数千个肿瘤样本中的生物标志物进行快速评估。尽管TMA问世还不到十年,但已被证明在肿瘤生物学研究、诊断测试开发以及肿瘤生物标志物研究中具有极高价值。本文综述了基于TMA的研究在临床肿瘤学中的影响及其未来潜在应用。同时也讨论了TMA构建的技术方面以及该技术固有的优缺点。
