Criteria for TNM Clinical Staging
Physical examination and history; pathologic examination of primary tumor or other tissue to establish a diagnosis of cancer, imaging, endoscopy, and studies to determine presence or absence of positive nodes and distant metastases.
Criteria for TNM Pathologic Staging
Tumor too widespread to be included in the definition for limited stage disease.
Note: patients with pleural effusion, contralateral supraclavicular nodes, or multiple ipsilateral lung tumors may be included in either stage because the size of the radiotherapy port has not been defined.
