A Pilot Study of Tumor and Critical Normal Tissue Motion in Head and Neck Cancer Using Cone Beam CT
In Brief
A clinical study evaluating Cone Beam Computed Tomography (CT) Scan for Head and Neck Cancer. Completed, enrolled 23 participants across 1 site.
Detailed Summary
Cone beam CT (computed tomography) is a developing technology which allows CT images to be obtained while a patient is on the radiation treatment table.(A CT scan uses x-rays to produce detailed pictures of structures in the body.) In this study, cone beam CT scans will be obtained before individual radiation treatment sessions for head and neck cancer. The information gathered from these scans will be used by the researchers to look at patient movement as well as changes in the amount of normal and tumor tissue throughout the course of radiation therapy. The researchers will use this information to create hypothetical radiation treatment plans, which will be used as the basis for future research. The cone beam CT scan data will not be used to alter the actual radiation treatment of any of the patients enrolled on the study. In addition, tests of salivary output and swallowing and questionnaires about quality of life will be made to assess how the doses of radiation affect them.

Interventions
Cone beam CT scan is considered a noninvasive procedure (meaning that the procedure does not require breaking the skin or any tools that physically enter the body). It will add a small amount of additional radiation dose (less than 1%) to the head and neck. The increase in the amount of radiation is only a very small amount more than what patients who get standard daily imaging receive. The amount of radiation from the cone beam CT scans is not significant (less than 1%) when compared to the amount of radiation generally received for treatment of head and neck cancer.
