T0 Lung Cancer T0 TNM Finding C60966 NCI Thesaurus Lung cancer without any evidence of a primary tumor. (from AJCC 6th and 7th Eds.)
T1 Lung Cancer T1 TNM Finding v7 C88868 NCI Thesaurus Lung cancer with a tumor size of 3 cm or less in greatest dimension, surrounded by lung or visceral pleura and without bronchoscopic evidence of invasion more proximal than the lobar bronchus (i.e., not in the main bronchus). The uncommon superficial tumor of any size with its invasive component limited to the bronchial wall, which may extend proximal to the main bronchus, is also classified as T1a. (from AJCC 7th Ed.)
T1a Lung Cancer T1a TNM Finding v7 C88869 NCI Thesaurus Lung cancer with a tumor size of 2 cm or less n greatest dimension, surrounded by lung or visceral pleura and without bronchoscopic evidence of invasion more proximal than the lobar bronchus (i.e., not in the main bronchus). The uncommon superficial tumor of any size with its invasive component limited to the bronchial wall, which may extend proximal to the main bronchus, is also classified as T1a. (from AJCC 7th Ed.)
T1b Lung Cancer T1b TNM Finding v7 C88870 NCI Thesaurus Lung cancer with a tumor size more than 2 cm but 3 cm or less in greatest dimension, surrounded by lung or visceral pleura and without bronchoscopic evidence of invasion more proximal than the lobar bronchus (i.e., not in the main bronchus). The uncommon superficial tumor of any size with its invasive component limited to the bronchial wall, which may extend proximal to the main bronchus, is also classified as T1a. (from AJCC 7th Ed.)
T2 Lung Cancer T2 TNM Finding v7 C88871 NCI Thesaurus Lung cancer with a tumor size more than 3 cm but 7 cm or less or tumor with any of the following features (T2 tumors with these features are classified T2a if 5 cm or less): Involves main bronchus, 2 cm or more distal to the carina; Invades visceral pleura (PL1 or PL2); Associated with atelectasis or obstructive pneumonitis that extends to the hilar region but does not involve the entire lung. (from AJCC 7th Ed.)
T2a Lung Cancer T2a TNM Finding v7 C88872 NCI Thesaurus Lung cancer with a tumor size more than 3 cm but 5 cm or less in greatest dimension. (from AJCC 7th Ed.)
T2b Lung Cancer T2b TNM Finding v7 C88873 NCI Thesaurus Lung cancer with a tumor size more than 5 cm but 7 cm or less in greatest dimension. (from AJCC 7th Ed.)
T3 Lung Cancer T3 TNM Finding v7 C88874 NCI Thesaurus Lung cancer with a tumor size more than 7 cm or one that directly invades any of the following: parietal pleural (PL3) chest wall (including superior sulcus tumors), diaphragm, phrenic nerve, mediastinal pleura, parietal pericardium; or tumor in the main bronchus (less than 2 cm distal to the carina but without involvement of the carina); or associated atelectasis or obstructive pneumonitis of the entire lung or separate tumor nodule(s) in the same lobe. (from AJCC 7th Ed.)
T4 Lung Cancer T4 TNM Finding v7 C88875 NCI Thesaurus Lung cancer with a tumor of any size that invades any of the following: mediastinum, heart, great vessels, trachea, recurrent laryngeal nerve, esophagus, vertebral body, carina, and separate tumor nodule(s) in a different ipsilateral lobe. (from AJCC 7th Ed.)
TX Lung Cancer TX TNM Finding C60965 NCI Thesaurus Lung cancer in which the primary tumor cannot be assessed, or in which the diagnosis is confirmed by the presence of malignant cells in sputum or bronchial washings, but not visualized by imaging or bronchoscopy. (from AJCC 6th and 7th Eds.)
Tis Lung Cancer Tis TNM Finding C60967 NCI Thesaurus Lung cancer with a finding of carcinoma in situ. (from AJCC 6th and 7th Eds.)
