was changed:
Non-small cell lung cancer (NSCLC) staging can be accomplished both by the TNM system or by the AJCC staging system.
The staging has since been revised - see - Lung cancer (IASLC 8th edition staging)
For a general discussion of these tumours please refer to the article on non-small cell lung cancer (NSCLC).
TNM system
The old 7th edition January 2010 NSCLC staging is as follows 4:
Primary tumour (T)
- Tx: malignant cells on cytology but no tumour found on bronchoscopy or imaging.
- Tis: carcinoma in situ
-
T1
- tumour size equal or less than 3 cm
- not involving the main bronchus
- T1a: smaller than 2 cm in longest dimension
- T1b: larger than 2 cm but smaller or equal to 3 cm
-
T2:
- tumour size more than 3cm but less/equal to 7cm or
- involving the main bronchus but >2 cm from carina
- visceral pleural involvement
- lobar atelectasis extending to the hilum but not collapse of the entire lung
- T2a: larger than 3 cm but smaller than 5 cm
- T2b: larger than 5 cm but smaller than 7 cm
-
T3
- tumour size more than 7 cm or
- tumour < 2 cm from carina but not involving trachea or carina
- involvement of the chest wall, including Pancoast tumour, diaphragm, phrenic nerve, mediastinal pleura or parietal pericardium
- separate tumour nodule(s) in the same lobe
- atelectasis or post-obstructive pneumonitis of the entire lung
-
T4
- any size tumour with:
- involvement of the trachea, oesophagus, recurrent laryngeal nerve, vertebra, great vessels or heart
- separate tumour nodules in the same lung but not in the same lobe
Nodal status (N)
- Nx: regional nodes cannot be assessed
- N0: no regional nodal metastases
- N1: ipsilateral peribronchial, hilar or intrapulmonary nodes, including direct invasion
- N2: ipsilateral mediastinal or subcarinal nodes
- N3: contralateral nodal involvement; ipsilateral or contralateral scalene or supraclavicular nodal involvement
Distant metastasis (M)
- Mx: distant metastases cannot be assessed
- M0: no distant metastases
-
M1: distant metastases present
- M1a: presence of a malignant pleural or pericardial effusion, pleural dissemination, or pericardial disease, and metastasis in opposite lung
- M1b: extrathoracic metastases
AJCC staging system
-
stage 0
- TNM equivalent: carcinoma in situ
- resectable: yes
-
stage I
- TNM equivalent: T1 or T2, N0, M0
- resectable: yes
- 5-year survival: 47%
-
stage IIa
- TNM equivalent: T1, N1, M0
- resectable: yes
-
stage IIb
- TNM equivalent: T2, N1, M0 or T3, N0, M0
- resectable: yes
- 5-year survival: 26%
-
stage IIIa
- TNM equivalent: T1 or 2, N2, M0 or T3, N1 or 2, M0
- resectable: yes
--------------- accepted cut off between resectable and non-resectable ----------
-
stage IIIb
- TNM equivalent: T1, 2 or 3, N3, M0 or T4, N0, 1, 2 or 3, M0
- resectable: no
- 5-year survival: 8%
-
stage IV
- TNM equivalent: any T, any N with M1
- resectable: no
- 5-year survival: 2%
Histological grade
- grade 1: well differentiated
- grade 2: moderately differentiated
- grade 3: poorly differentiated
- grade 4: undifferentiated
