Overview
Adenocarcinoma of the lung may be classified into several subtypes based on TNM and UICC staging system.[1]
Staging
TNM staging[1]
TNM | Definition | |
---|---|---|
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. |
UICC staging[1]
Stage | T | N | M |
---|---|---|---|
Occult carcinoma | TX | N0 | M0 |
Stage 0 | Tis | N0 | M0 |
Stage IA | T1 | N0 | M0 |
Stage IB | T2 | N0 | M0 |
Stage IIA | T1 | N1 | M0 |
Stage IIB | T2 | N1 | M0 |
T3 | N0 | M0 | |
Stage IIIA | T1 | N2 | M0 |
T2 | N2 | M0 | |
T3 | N1 | M0 | |
T3 | N2 | M0 | |
Stage IIIB | Any T | N3 | M0 |
T4 | Any N | M0 | |
Stage IV | Any T | Any N | M1 |
