N1

N3
Stadio IIIA (N2)
Subsets
IIIA 1
Metastasi “single station” identificate
all’esame istologico definitivo
(metastasi linfonodali microscopiche occulte)
IIIA 2
Metastasi “single station”
riconosciute intraoperatoriamente
IIIA 3
N2 potenzialmente resecabile
(identificato preoperatoriamente)
IIIA 4
N2 “bulky multistation” non resecabile
Eterogeneità dell’ N2
 Single N2 disease significantly better survival than
multiple N2 disease
 Tumor in the upper lobe significantly longer
survival than with middle/lower lobe involvement
 Single N2 disease with NSCLC in the upper lobe
good candidates for pulmonary resection
(3- and 5-y survival 74,9% and 53,5%)

N2 sottocarenale
Surgery for pts with T1-3 N2 NSCLC
might be accettable if subcarinal lymph node metastasis
is predicted to be absent
