Use of High Dose Radiation Followed by Chemotherapy and Radiation to Treat Locally Advanced NSCLC

Inclusion Criteria Subjects must meet all the following criteria: * Histologic or cytologic documentation of NSCLC (all histologies allowed) * Stage II or III disease (AJCC 7th Edition) based on imaging as required during screening: Stage II disease includes only subjects with medically inoperable N1 disease otherwise meeting eligibility criteria. Primary tumor ≤ 7 cm * Subjects with non-malignant pleural effusion identified on CT scan are eligible provided the effusion is not known or demonstrated to be an exudative effusion. If a pleural effusion is present, the following criteria must be met to exclude malignant involvement: A pleuracentesis is required if pleural fluid is present and visible on both CT scan and chest x-ray. Pleural fluid cytology must be negative for malignancy. Effusions that are minimal and too small for pleuracentesis as determined by the investigator will be eligible for enrollment. * FEV1 ≥ 1.0 Liter or ≥ 40% predicted with or without bronchodilator within six months prior to initiation of study treatment. Subjects who meet the criterion without O2, but who need acute (started within 10 days prior to enrollment) supplemental oxygen due to tumor-caused obstruction/hypoxia are eligible, provided the amount of the O2 needed has been stable. * Age ≥18 years. * ECOG performance status ≤ 2 * Subjects must have normal organ and marrow function as defined: Leukocytes ≥4,000/mcL; Absolute neutrophil count ≥1,500/mcL; Platelets ≥100,000/mcL; Total bilirubin …
