Overview
Adenocarcinoma of the lung may be classified into several subtypes based on TNM and UICC staging system.
Staging
TNM staging:[1]
TNM | Definition | |
---|---|---|
TX | Primary tumor cannot be assessed, or tumor is proven by the presence of malignant cells in sputum or bronchial washings but not visualized by imaging or bronchoscopy. | |
T0 | No evidence of primary tumor. | |
Tis | Carcinoma in situ.
Squamous cell carcinoma in situ (SCIS) Adenocarcinoma in situ (AIS): adenocarcinoma with pure lepidic pattern, ≤ 3 cm in greatest dimension | |
T1 | Tumor is 3 cm or less in size and has not spread to the visceral pleura or the main bronchi. | |
T1a – Tumor is smaller than 2 cm. | ||
T1b – Tumor is larger than 2 cm, but smaller than 3 cm. | ||
T2 | Tumor is larger than 3 cm, but smaller than 7 cm; or the tumor has any of the following features: Cancer has spread to the main bronchi, but is not closer than 2 cm to the carina; cancer has spread to the visceral pleura; tumor is associated with obstructive pneumonitis or atelectasis. | |
T2a – Tumor is larger than 3 cm, but 5 cm or less in size. | ||
T2b – Tumor is larger than 5 cm, but 7 cm or less in size | ||
T3 | A tumor with any of the following: Invasion of the chest wall, diaphragm, mediastinal pleura, or parietal pericardium; extension into the main bronchus, within 2 cm of the carina, but not involving the carina; obstructive pneumonitis of the entire lung. | |
T4 | A tumor with any of: Invasion of the mediastinum, heart, great vessels, trachea, esophagus, vertebra, or carina; Separate tumor 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 | ||
M0 | No distant metastasis. | |
M1 | Distant metastasis is present. | |
M1a – Any one of the following: separate tumour nodule(s) in the opposite lung; tumor nodules on the parietal pleura; pleural effusion or pericardial effusion. | ||
M1b – Distant metastasis. |
UICC staging[1]
Stage | T | N | M |
---|---|---|---|
Occult carcinoma | TX | N0 | M0 |
Stage 0 | Tis | N0 | M0 |
Stage IA | T1 | N0 | M0 |

Stage IIA | T2b | N0 | M0 |
T1 | N1 | M0 | |
T2a | N1 | M0 | |
Stage IIB | T2b | N1 | M0 |
T3 | N0 | M0 | |
Stage IIIA | T1 | N2 | M0 |
T2 | N2 | M0 | |
T3 | N1 | M0 | |
T3 | N2 | M0 | |

T4 | N1 | M0 | |
Stage IIIB | T4 | N2 | M0 |
Any T | N3 | M0 | |
Stage IV | Any T | Any N | M1 |
