The article deals with lung cancer staging. A general discussion of staging is found in cancer staging.
General
The clinical staging and pathologic staging are concordant in only approximately ~50% of cases.[1]
TNM staging system
Tumour
| T stage | Size/criteria | Other requirements | Comment |
|---|---|---|---|
| T0 | (no tumour) | rare | |
| Tis | no invasion | rare | |
| T1a | <=2 cm | confined to lung, no VPI, no main branch bronchus involvement | |
| T1b | >2 cm, <=3 cm | confined to lung, no VPI, no main branch bronchus involvement | |
| T2a | >3cm or VPI or main branch bronchus involvement, <= 5cm | confined to lung, no total lung collapse | |
| T2b | >5cm or VPI or main branch bronchus involvement, < 7cm | confined to lung, no total lung collapse | |
| T3 | >7 cm or 2 or more nodules or total lung collapse | ||
| T4 | extension beyond the lung |
Lymph nodes
| N stage | Criteria | Comment |
|---|---|---|
| N0 | no lymph node metastases | |
| N1 | metastasis in any ipsilateral node | includes hilar, peribronchial & intrapulmonary nodes; direct extension also counts |
| N2 | metastasis in any ipsilateral mediastinal node or subcarinal node | |
| N3 | metastasis in any contralateral node, scalene node or supraclavicular node |
Lymph nodes stations
| Station number | Location | Staging |
|---|---|---|
| Station 1 | lower cervical, supraclavicular, sternal notch | N3 for supraclavicular, N2 for others |
| Station 2 | upper paratracheal nodes | N2 |
| Station 3 | prevascular (anterior) and retrotracheal (posterior) | N2 |
| Station 4 | lower paratracheal (right and left) | N2 |
| Station 5 | subaortic/aorto-pulmonary window | N2 |
| Station 6 | Para-aortic (phrenic or asc. aorta) | N2 |
| Station 7 | subcarinal | N2 |
| Station 8 | paraesophageal | N2 |
| Station 9 | pulmonary ligament | N2 |
| Station 10 | hilar nodes (left and right) | N1 |
| Station 11 | interlobar nodes (left and right) | N1 |
| Station 12 | lobar | N1 |
| Station 13 | segmental | N1 |
| Station 14 | subsegmental | N1 |
