Patient Evaluation for Head and Neck Surgery Branch Studies

This purpose of this protocol is to evaluate and identify patients who may be eligible for actively enrolling NIH clinical research protocols for head and neck cancer; or provide standard evaluations and treatment necessary for patients with head and neck cancers enrolled in other NIH clinical protocols that do not include such treatment. Participants screened under this protocol will not be required to join a research study; the decision will be voluntary. Patients with head and neck cancer may enroll in this study. Participants may undergo various tests, described below, to determine their eligibility for participation in a specific clinical trial. Other tests may also be required, depending on the protocol or treatment for which the patient is being considered: * Blood tests About 3 to 5 tablespoons of blood will be drawn for routine tests, HLA typing and hepatitis and HIV screening. * Magnetic resonance imaging (MRI) This imaging procedure uses a powerful magnetic field to produce pictures of parts of the body in small section views. The test does not use radiation and may be done with or without a contrast dye material. * Computerized tomography (CT) This procedure uses x-rays to produces three-dimensional images of body organs in small section views. A contrast dye may or may not be used. * Positron emission tomography (PET) PET scans allow the doctor to see the activity of cells in specific body tissues. It requires injection of a radioactive material that attaches to a sugar fluid. The fluid goes to very active cells, such as cancer cells, revealing tumors. * Pulmonary function tests These tests use a machine the patient breathes into to measure the volume of air the patient can move in and out of the lungs. * Arteriogram, or angiogram The anatomy of the blood vessels can be seen using this procedure, which involves placing a small catheter (plastic tube) into an artery and injecting a contrast solution. Special X-rays are then taken to show the blood vess
