支气管肺癌的分级在选择治疗方法和估计预后中具有重要参考价值。自Denoix设计的TNM(Tumor Nodal-involtment Metastasis)分级系统为国际抗癌联盟(International Union Against Cancer, IUAC)认可并于1974年首次发表后,在放射、气管镜、肺科、外科、肿瘤以及病理诸学科之间架起了一座桥梁,使以上各科学者在肺癌分级的评价中有了共同语言和参照标准。1986年,经过修订的新的肺癌国际分级系统的出台,使肺癌的临床分级和选择治疗方法更科学。在肺癌TNM分级系统中,淋巴结受累或转移(N)的分期是其重要组成部分,也是估计预后的主要依据,对此有较多研究,
The grading of bronchial lung cancer has important reference value in selecting treatment methods and estimating prognosis. The Denimix-designed Tumor Nodal-involtment Metastasis (TNM) grading system was approved by the International Union Against Cancer (IUAC) and first published in 1974 after radiology, bronchoscopy, pulmonology, surgery, oncology, and pathology. A bridge has been set up between the various disciplines, so that the above scientists have common language and reference standards in the evaluation of lung cancer grading. In 1986, the revised new international classification system for lung cancer was introduced, making the clinical classification and selection of treatment methods for lung cancer more scientific. In the TNM classification system of lung cancer, the stage of lymph node involvement or metastasis (N) is an important part of it, and it is also the main basis for estimating the prognosis. There are many studies on this,
