Primary outcomePrimary: Overall Survival (OS) Rate — 54.2 percentage of patients
Summary
This phase II trial studies how well positron emission tomography (PET)/computed tomography (CT) and single positron emission computed tomography (SPECT)/CT imaging works in improving radiation therapy treatment in patients with stage IIB-IIIB non-small cell lung cancer. PET/CT imaging mid-way through treatment may be able to accurately show how well radiation therapy and chemotherapy are working. SPECT/CT imaging may be able to tell which parts of the lung tissue are healthier than others. Based on the result of the imaging, treatment adjustments may be made to the radiation therapy to improve survival and decrease toxicity.

Eligibility Criteria
Inclusion Criteria
- Pathologically proven (either histologic or cytologic) diagnosis of stage IIB-IIIB non-small cell lung cancer (NSCLC); according to American Joint Committee on Cancer (AJCC) staging, 7th edition
- Staging workup must include: brain imaging (CT head or magnetic resonance imaging [MRI] brain) and PET/CT
- Pleural effusions must have cytology to rule out malignant involvement unless too small to undergo thoracentesis per radiology
- Patients must be considered unresectable or inoperable
- Patient must not have received prior radiation for this lung cancer
- Patients must be having concurrent chemotherapy
- Nodal recurrences can be treated on this protocol but prior curative surgery for lung cancer must have been at least 6 months prior to the nodal recurrence
- Patients must have measurable or evaluable disease that is FDG avid with standardized uptake value (SUV) > 3 on PET/CT
- Zubrod performance status 0-1
- PFTs including forced expiratory volume in 1 second (FEV1) within 26 weeks prior to registration; for FEV1, the best value obtained pre- or post-bronchodilator must be >= 0.8 liters/second or >= 50% predicted
- Blood cell count (CBC)/differential obtained within 8 weeks prior to registration on study
- Absolute neutrophil count (ANC) >= 1, 800 cells/mm^3
- Platelets >= 100,000 cells/mm^3
- Hemoglobin >= 10.0 g/dl (Note: The use of transfusion or other intervention to achieve hemoglobin (Hgb) >= 10.0 g/dl is acceptable)
- Serum creatinine within normal institutional limits or creatinine clearance >= 40 ml/min
- Bilirubin must be within or below normal institutional limits
- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) 10% unintentional weight loss within the past month
- Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 3 years; non-invasive conditions such as carcinoma in situ of the breast, oral cavity, or cervix are all permissible
- Prior radiotherapy to the region of the study cancer that would result in overlap of radiation therapy fields
- Pregnancy or women of childbearing potential and men who are sexually active and not willing/able to use medically acceptable forms of contraception
