NCIt definition : Stage IA includes: (T1a, N0, M0); (T1b, N0, M0). T1a: Lung cancer with a tumor size
of 2 cm or less in greatest dimension, surrounded by lung or visceral pleura and without
bronchoscopic evidence of invasion more proximal than the lobar bronchus (i.e., not
in the main bronchus). The uncommon superficial tumor of any size with its invasive
component limited to the bronchial wall, which may extend proximal to the main bronchus,
is also classified as T1a. T1b: Lung cancer with a tumor size more than 2 cm but 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 (i.e., not
in the main bronchus). N0: No regional lymph metastasis. M0: No distant metastasis.
