[A non-small cell lung cancer (NSCLC), histologically classified as large cell carcinoma. No distant metastasis. Various extents of tumor size and aggressiveness, and of regional lymph node metastasis. Subclassified as Stage IIA (T1,N1,M0) or Stage IIB (either T2,N1,M0 or T3,N0,M0). N0: no regional lymph node metastasis. N1: regional metastasis to ipsilateral peribronchial and/or ipsilateral hilar lymph nodes, and intrapulmonary nodes including involvement by direct extension of the primary tumor. T1: tumor is 3 cm or less in greatest dimension, surrounded by lung or visceral pleura, and without bronchoscopic evidence of invasion more proximal than the lobar bronchus. T2: tumor has any of the following features of size or extent: more than 3 cm in greatest dimension; involves the main bronchus, 2 cm or more distal to the carina; invades the visceral pleura; associated with atelectasis or obstructive pneumonitis that extends to the hilar region but does not involve the entire lung. T3: tumor (of any size) directly invades any of the following: chest wall (including superior sulcus tumors), diaphragm, mediastinal pleura, parietal pericardium; or tumor in the main bronchus less than 2 cm distal to the carina but without involvement of the carina; or associated atelectasis or obstructive pneumonitis of the entire lung.
