Initial staging is a key part of the initial evaluation of non-small cell lung cancer. It relies on the 7th edition of the TNM classification. Proposals have been recently developed for the 8th edition of the classification, which is due to be enacted in early 2017. Among these proposals, the weight of tumor size has been increased and new N descriptors have been introduced to further describe N category depending on the number station involved. Regarding M descriptors, oligometastatic disease is distinguished from multiple distant extrathoracic metastases.
初始分期是非小细胞肺癌初始评估的关键部分。它依据第7版TNM分类。最近已针对第8版分类提出了建议，该版分类将于2017年初颁布。在这些建议中，肿瘤大小的权重增加了，并且引入了新的N描述符，以根据受累淋巴结站数进一步描述N类别。关于M描述符，寡转移疾病与多个远处胸外转移相区分。
