Total Body Composition in Detection of Nutrition Depletion in Head and Neck Patients

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to define the role of total body composition in the guidance of nutritional support and treatment monitoring in head and neck patients. Furthermore, the second aim of this study is to compare the clinical performance of dual energy X-ray absorptiometry as compared to CT in evaluating total body composition of patients.

Detailed Description
-----------------
In this 4-year cohort study, a total of 120 patients with stage III-IV head and neck cancer (squamous cell carcinoma) patient undergoing concurrent chemo-radiotherapy will be enrolled. Laboratory examination will be performed to evaluate the physiological change and treatment related toxicity, including BUN and Cr for hydration and renal function; complete blood cell and differential count, pre-albumin and albumin for nutrition, and C-reactive protein for inflammatory change. Both CT and dual energy X-ray absorptiometry (DXA) will be used to evaluate total body composition. CT is used to evaluate surface area of fat and muscle, and DXA is used to evaluate lean body mass, fat body mass and bone mineral content. MRI of the head and neck region is used for tumor staging of the head and neck cancer, monitoring the treatment response and detecting treatment related adverse effect.

Ability to understand and willingness to be enrolled in our study and sign a written informed consent document Exclusion Criteria: NPC is excluded from this study. Patients have acute medical conditions (such as bacterial or viral infection or active cardiopulmonary disease) that may be incapable of having regular image study. Patients are under regular steroid or hyperthyroid medications, which may have great impact on the whole body metabolism. Patients are under-nutrient and they need to have regular liquid oral nutrition formulas support. Patient that have dementia or pregnant. Patients not expecting to comply with follow up. Patient not suitable for chemotherapy. Patient not suitable for MRI, such as claustrophobia, previous metal implantation, previous cardiac pacemaker implantation, inability to comply with MRI instructions and poor renal function. Received barium study within a week.
