Overview
According to the American Joint Committee on Cancer (AJCC) staging system, there are 4 stages squamous cell carcinoma of the lung, based on 3 factors: tumor size, lymph node invasion, and metastasis. Each stage is assigned a letter and a number that designate T for tumor size, N for node invasion, and M for metastasis.

- The table below summarizes the TNM staging system for the diagnosis of non-small cell lung cancer[1]
TNM | Description | |
---|---|---|
TX | The primary tumour cannot be assessed, or there are malignant cells in the sputum or bronchoalveolar lavage but not seen on imaging or bronchoscopy | |
T0 | No evidence of primary tumor | |
Tis | Carcinoma in situ | |
T1 | Tumour less than 3 cm in its greatest dimension, surrounded by lung or visceral pleura and without bronchoscopic invasion into the main bronchus. | |
T2 | A tumour with any of: more than 3 cm in greatest dimension; Extending into the main bronchus, but more than 2 cm distal to the carina; Obstructive pneumonitis, but not involving the entire lung | |
T3 | A tumour with any of: invasion of the chest wall, diaphragm, mediastinal pleura, or parietal pericardium; Extending into the main bronchus, within 2 cm of the carina, but not involving the carina; Obstructive pneumonitis of the entire lung | |
T4 | A tumour with any of: invasion of the mediastinum, heart, great vessels, trachea, oesophagus, vertebra, or carina; Separate tumour nodules in the same lobe; Malignant pleural effusion | |
Regional Lymph Nodes | ||
NX | Lymph nodes cannot be assessed | |
N0 | No lymph nodes involved | |
N1 | Metastasis to ipsilateral peribronchial or ipsilateral hilar lymph nodes | |
N2 | Metastasis to ipsilateral mediastinal or subcarinal lymph nodes | |
N3 | Metastasis to any of: ipsilateral supraclavicular lymph nodes; Ipsilateral scalene lymph nodes; Contralateral lymph nodes. | |
Distant Metastasis | ||
MX | Distant metastasis cannot be assessed | |
M0 | No distant metastasis | |
M1 | Distant metastasis is present |
