PHÂN LOẠI TNM TRONG UNG THƯ PHỔI PHIÊN BẢN 8 – NHỮNG ĐIỂM CHẨN ĐOÁN HÌNH ẢNH CẦN LƯU Ý

Abstract

The TNM cancer classification system (T: stands for Tumor, meaning U; N: stands for Node, means lymph nodes; and M: stands for Metastasis, meaning metastasis) is UIAC (Union International Against Cancer) was first introduced in 1944 of the last century, and was officially published as a paper book in 1968. This classification system since its inception includes 5 goals, so far still unchanged: (1) Assistance in treatment planning; (2) Prognosis of disease condition; (3) Evaluation of treatment results; (4) Make it easier to exchange and compare information between treatment facilities (due to the common use of a unified system); (5) As a basis to contribute to the study of malignancies. Since 1987, UIAC has cooperated with AJCC (American Joint Committee on Cancer) to continue to research and improve the TNM classification system, turning it into a world standard classification system in cancer, including lung cancer. The official TNM versions that have been announced include: 5; 6; 7; 8. Version 8 was announced in 2017 and has been in use ever since. This article will specifically interpret imaging situations in order to unify their use in clinical practice.
