Stereotactic Body Radiotherapy (SBRT) Versus Sublobar Resection for High-Risk Patients Non-Small Lung Cancer

This randomized phase II trial is for medically inoperable early stage non-small cell lung cancer (NSCLC) patients. It is designed to compare the number of patients who are disease free and alive at 2 years between Stereotactic Body Radiotherapy (SBRT) and surgical intervention arms. SBRT is less invasive and felt to be equally effective to surgery for early stage NSCLC. Surgery is currently the standard of care for these patients. The hypothesis of this study is that SBRT is at least as good as surgery for disease free survival at 2 years.
