Summary
Brief summary (as posted)
RATIONALE: Laser surgery for cancer of the larynx may have fewer side effects and improve recovery. Radiation therapy uses high-energy x-rays to damage tumor cells. Combining radiation therapy and laser surgery may kill more tumor cells. PURPOSE: Phase II trial to study the effectiveness of laser surgery plus radiation therapy in treating patients with early stage cancer of the larynx.
