Radiation with or without chemotherapy for recurrent throat cancer

This trial is testing whether combining cisplatin (a chemotherapy drug) with radiation therapy works better than radiation therapy alone for people whose nasopharyngeal cancer has come back after their first treatment. The study wants to see if adding the medication helps control the cancer better and causes fewer serious side effects over time.

When nasopharyngeal cancer returns after initial treatment, radiation alone doesn't always control it well enough, and it can cause serious long-term side effects. Researchers hope that adding chemotherapy will improve how well the treatment works while reducing harmful effects.
