Overview
Brief Summary
This phase I trial studies the side effects and best dose of radiation therapy when given together with cisplatin and etoposide in treating patients with non-small cell lung cancer that cannot be removed by surgery. Radiation therapy uses high energy x rays to kill tumor cells. Drugs used in chemotherapy, such as cisplatin and etoposide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Drugs, such as cisplatin, may make tumor cells more sensitive to radiation therapy. Giving radiation therapy together with cisplatin and etoposide may kill more tumor cells.
Detailed Description
PRIMARY OBJECTIVES: I. To determine the maximum tolerated dose (MTD) of escalating doses of radiotherapy (RT) administered concomitantly with a fixed dose of cisplatin and etoposide within the same overall treatment time. OUTLINE: This is a dose-escalation study of radiation therapy. Patients undergo 3-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) 5 days a week for 8 weeks. Patients also receive cisplatin intravenously (IV) over 60 minutes on days 1, 8, 28, and 36 and etoposide IV over 60 minutes on days 1-5 and 28-32. After completion of study treatment, patients are followed up at 8 weeks and 6 months.

Outcomes
Primary Outcomes
MTD of radiotherapy, in terms of number of daily fractions, that can be delivered using 3D-CRT or IMRT with the standard cisplatin/etoposide regimen
Time Frame: Up to 8 weeks after completion of radiotherapy
The MTD will be the highest dose at which no more than one of six patients experience a dose-limiting toxicity. Toxicity will be scored using the National Cancer Institute Common Toxicity Criteria version 4.0.
