T2 means that either the mass is >3cm in diameter or has encroached upon the pleura or main bronchus 2 cm from carina or focal collapse of lung.
N2 means that the tumor has involved the lymph nodes in direct extension plus ipsilateral mediastinal or subcarinal nodes.
M0 means no metastatis to distant organ.
Sorry, really dont know about prognosis, but the tumor is certainly within the lung and its adjoining lymph nodes but non small cell tumors respond poorly to chemotherapy. So the doctors know the best about his health and life expectancy.
I really hope that he lives a healthy and long life.
