Boosting Treatment for Head and Neck Cancer After Surgery

This trial studies how well radiation therapy works with or without a drug called cisplatin for patients who have stage III-IVA squamous cell carcinoma of the head and neck. The goal is to find out which approach helps patients more after they have had surgery. Radiation therapy uses high-energy rays to kill cancer cells, while cisplatin is a chemotherapy drug that helps stop the growth of these cells in different ways. Researchers want to see if combining these treatments is better than radiation alone.
