Lung Cancer Staging Flashcards
N1
Меtaѕtаsis in ipsilateral peribronchial and/or ipsilateral hilar lymph node(s) and intrapulmonary nodes
N2
Меtаstаѕis in ipsilateral mediastinal and/or subcarinal lymph node(s)
N3
Меtaѕtаѕiѕ in contralateral mediastinal, contralateral hilar, ipsilateral or contralateral scalene, or supraclavicular lymph node(s)

T2a and T2b (location)
Lung
- bronchus/hilum
- visceral pleura
- atelectasis/pneumonitis (b/c obs)
T1 (location)
Surrounded by lung or visceral pleura (NO invasion more proximal than lobar bronchus)
T3 Location
3 places:
- 3 looks like p–> pericarditis and phrenic nerve
- 2 3s together looks like 2 nodules in same lobe
- Chest wall
T4 Location
midline (mediastinum and spine)
diaphragm
