Blood Tests and Questionnaires in Studying Adherence to Preventative Swallowing Exercises in Participants with Head and Neck Cancer

Trial Status: active

This trial uses blood tests and questionnaires to study how well participants with head and neck cancer adhere to swallowing exercises to prevent future disease. Using blood tests to study cytokines (proteins related to the immune system) may help doctors learn if certain levels of cytokines affect whether or not side effects occur and if they put participants at risk for future disease. Questionnaires may help doctors learn about the reasons head and neck cancer participants may or may not follow the swallowing exercises that they are asked to perform after receiving radiation treatments.
