Gastro-esophageal Reflux | Evaluation of Esomeprazole in Treating Gastro-esophageal Reflux Disease (GERD) in Head and Neck Cancer Patients Exposed to Radiation Therapy
Gastro-esophageal Reflux research study
What is the primary objective of this study?
The purpose of this research study is to measure acid reflux into the throat both before and after medical treatment in people who have had radiation therapy to their head and neck for the treatment of cancer. Many people who have received head and neck radiation therapy develop a dry mouth as a result of the radiation damage to their saliva glands. In addition to the discomfort associated with a dry mouth, the decrease in saliva may increase the severity of gastro-esophageal reflux disease (acid reflux). Acid reflux occurs when acid escapes from your stomach into your throat. You may not have any symptoms of acid reflux, but often it can cause symptoms of heartburn or chest discomfort. Acid reflux can be treated once it is diagnosed. Treatment consists of dietary changes, behavioral alterations, and medication. Medications are available that decrease the amount of acid in your stomach. Diagnosis of acid reflux is made with a pH-probe to test for acid in your throat.

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?
Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.
Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
