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 visceral pleural invasion (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 N Staging ‡
Station 1 lower cervical, supraclavicular, sternal notch N3 for supraclavicular,[2]
N2 for others
Station 2 upper paratracheal nodes (left and right) 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 (left and right) N1
Station 13 segmental (left and right) N1
Station 14 subsegmental (left and right) N1

Note:

  • ‡ Contralateral lymph node involvement is N3.[3]
