Summary
This study compares the results of surgery to stereotactic body radiation therapy (SBRT) in patients with stage I non-small cell lung cancer (NSCLC). Both surgery and SBRT are standard treatments for this kind of lung cancer. Surgery removes the cancer but is more invasive and may have more complications. Radiation therapy uses high energy x-rays, particles, or radioactive seeds to kill cancer cells and shrink tumors. SBRT uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue. Information gathered from this study may help researchers find out if SBRT is as effective as surgery in treating patients with stage I NSCLC.
