A Comprehensive Prospective Study on the 10-Year Outcome and Late Toxicity, Quality of Life of Reduced Volume Intensity Modulated Radiation Therapy in Nasopharyngeal Carcinoma

Nasopharyngeal carcinoma (NPC) is a type of head and neck cancer. The last three decades of research in head and neck radiation oncology have largely focused on improvements in survival, which have mostly come at the cost of long term toxicity for surviving patients.This is an observational study that is being done to evaluate the long-term efficacy, learn about the toxicity and quality of life that survivors of nasopharyngeal carcinoma may have following treated with reduced volume intensity modulated radiation therapy.
