现行的肺癌TNM分期标准已暴露出不足,而新的标准即将面世。分子分期(molecular staging)的概念进入人们的视野,由于它能够发现常规手段无法检测到的微转移灶(micro-metastasis),为临床上对肺癌的TNM分期进行更加严谨的界定提供了科学依据,因而受到各国学者的关注。全文介绍新的TNM分期标准的变化,并对国内外关于肺癌的分子分期研究进行综述。 The current TNM staging criteria for lung cancer have been exposed inadequately, and new standards are forthcoming. The concept of molecular staging enters the field of vision. Because it can find micro-metastases that can not be detected by conventional methods, it provides a scientific basis for more rigorous definition of TNM staging of lung cancer. Which has drawn the attention of scholars in various countries. The full text introduces the new TNM staging standards changes, and reviews the molecular staging of lung cancer at home and abroad.
