Widefield Fluorescence and Reflectance Imaging Systems and Oral Tissue Samples in Monitoring Participants at Risk for Developing Oral Cancer

This clinical trial studies widefield fluorescence and reflectance imaging, fluorescence spectroscopy, and tissue samples in regularly examining (monitoring) participants at risk for developing oral cancer. All tissue and cells are made of tiny particles. Some of these particles give off small amounts of light. This light is called fluorescence. Fluorescent imaging use instruments that shine different wavelengths (colors) of light in the mouth taking fluorescence pictures through a portable head light or by taking fluorescent and reflectance pictures through a dental microscope using a digital camera. Fluorescent spectroscopy uses a small probe placed gently against the lining of the mouth and the tissue is exposed to small amounts of fluorescent light that is then collected with a special camera and a computer to be analyzed. Checking mouth tissue samples under a microscope may also help detect abnormal cells. Diagnostic procedures, such as fluorescence and reflectance imaging, fluorescence spectroscopy imaging, and tissue samples, may help doctors detect pre-cancer or early cancer when it may be easier to treat.

Early Prediction of Oral Cancer by S100A7 Immunohistochemistry Signature-based Assessment

The purpose of this observational study is to evaluate the utility of the S100A7 immunohistochemistry signature-based assessment - STRATICYTE - in determining the risk of progression to cancer of clinically suspicious oral lesions.

Arabic PRO Measures for Head and Neck Cancer Radiotherapy.

The goal of Arabic patient-reported outcome measures during radiotherapy for head and neck cancer is to test the patient-reported outcome measure (PROM) tools. PROM tools are not validated cross-culturally in Arabic-speaking patient populations, which limits their use in our clinical setting. Validation of these PROM tools will allow clinicians to identify the concerns related to our patient population and measure the outcome of our interventions. Main objectives are: * To further validate (cross-culture) the PROM instruments related to head and neck cancer (HNC) in Arabic patients. * To investigate the prevalence and severity of the patient-reported concerns and their relevance with demographics and clinical characteristics. The participants will be given tasks to complete 6 tools survey before, during, and after radiotherapy.
