近年来，随着分子生物学等基础医学研究的快速发展和医学模式的转变，诞生了转化医学的概念。转化医学是将医学生物学基础研究成果迅速、有效地转化为可在临床实际中应用的理论、技术、方法和药物，在实验室与病房（bench to bedside）之间架起相互沟通的桥梁。目前，肿瘤分子标志物的研究进展迅速，越来越多的研究成果正在成为肿瘤诊断、治疗、预后及疗效监测的有效工具，是转化医学模式的重要体现。

Recently, the concept of translational medicine has come into being with the fast development of basic medicine such as molecular biology and change of medical mode. The aim of translational medicine is to quickly and effectively translate the basic research achievement of medical biology into theories, technologies, methods and drugs for clinical application, which paves a way from bench to bedside. With the fast research progress of tumor molecular biomarkers, more and more findings have been used for tumor diagnosis, treatment, prognosis and curative effect surveillance, which is an important embodiment of translational medicine.
