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 |
