Rationale: Surgery remains the standard of care for stage 1 (T1-2a N0)non-small cell lung cancer. Stereotactic body radiation therapy is a newer radiation treatment that gives fewer but higher and possibly more effective doses of radiation than standard radiation. This technique may be able to send x-rays directly to the tumor and cause less damage to normal tissue. It is not yet known whether stereotactic body radiation therapy is more effective than surgery in treating non-small cell lung cancer. Purpose: The primary aim of this randomized phase II trial is to determine if the efficacy of SBRT is comparable to that of standard surgical interventions for patients with T1N0 non-small cell lung cancer.
