Lung Cancer Flashcards
T1 NSCLC
<=3cm
confined to lobar bronchus
T2 NSCLC
>3cm <=5cm or main bronchus (without carina involvement) visceral pleura invasion causing atelectasis/pneumonitis
T3 NSCLC
>5cm <=7cm or >1 tumor in same lobe invasion of - chest wall - phrenic - pericardium
T4 NSCLC
>7cm or >1 tumor in a different ipsilateral lobe invasion of - diaphragm - mediastinum - heart - great vessels - trachea, carina - recurrent laryngeal - goos - vertebrae
N1 NSCLC
ipsilateral peribronchial nodes +/- hilar nodes
and
intrapulmonary nodes (Stations 10-14)
N1 alters prognosis but not management
N2 NSCLC
ipsilateral mediastinal (Stations 2-4, 8-9)
or
subcarinal lymph nodes (Station 7)
N3 NSCLC
contralateral mediastinal +/- hilar nodes
or
scalene/supraclavicular nodes (either side)
unresectable
M1a NSCLC
separate tumors in contralateral lobe
or
tumor with pleural/pericardial nodes or malignant effusion (pleural or pericardium)
M2a NSCLC
single extrathoracic met
M3a NSCLC
MC Met
multiple extrathoracic met (1+ organs)
bone, then lung, brain, liver, adrenal
Stage I NSCLC
T1-2a N0
Stage II NSCLC
T1-2 N1
or
T2-3 N0
Stage III NSCLC
T1-2 N2 T3 N1 T4 NX or TX N3
Stage IV NSCLC
TXNXM1
Distinction between Nodal Stations 10 and 4
N1 vs N2
Station 10: most proximal pulmonary nodal station
Station 4: lower paratracheal (mediastinal)
Right: lower border of azygos vein
Left: upper border of PA
Below this is station 10(N1), above this is station 4(N2)
