TNM分类法是应用最广泛的肿瘤分期系统。最新版本(1987年)包括了基于影象学而发生的重要变化,这是以前的版本中(1978年)所没有的。本文的目的是使人们重视影象学在TNM分类上的应用及肿瘤分期的方式已经改变。综合应用US、CT、MR、核医学和内腔超声可容许行肿瘤的术前分期,这在旧TNM分类版本中未反映出。尽管有上述变化,大多数术前TNM评估仍由非放射医师运用放射医师提供的资料作出。我们希望通过在肿瘤分期中运用放射医师的发现,鼓励他们对TNM分期的兴趣,使他们在肿瘤分期上充当更主动的角色,促使TNM分期有更大进步。
The TNM classification is the most widely used tumor staging system. The latest version (1987) included important changes that occurred based on imagery, which was not available in previous versions (1978). The purpose of this paper is to make people pay attention to the application of imaging in TNM classification and the way of tumor staging has changed. Comprehensive application of US, CT, MR, nuclear medicine, and intraluminal sonography may allow preoperative staging of tumors, which is not reflected in the old TNM classification version. Despite these changes, most preoperative TNM assessments are still made by non-radiologists using information provided by radiologists. We hope that by using the findings of radiologists in the staging of tumors to encourage them to interest in TNM staging, they will be able to play a more active role in tumor staging and make TNM staging more progress.
