Surgery With or Without Internal Radiation Therapy in Treating Patients With Stage I Non-Small Cell Lung Cancer

This randomized phase III trial studies surgery and internal radiation therapy to see how well they work compared to surgery alone in treating patients with stage I non-small cell lung cancer. Surgery may be an effective treatment for non-small cell lung cancer. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. It is not yet known whether surgery and internal radiation therapy are more effective than surgery alone in treating non-small cell lung cancer.
