The study will include 60, ≥18 year old patients (of both genders) with head and neck cancers receiving concurrent radiation and chemotherapy treatment. Patients with any pathologically proven head and neck squamous cell carcinoma, except those of the nasopharynx and sinus will be eligible, if there is no evidence of metastatic disease. Patients with previous chemotherapy or radiation treatment will be excluded. A Karnofsky performance status ≥60% or more is required. Patients with significant cardiac, chest or gastrointestinal comorbidities will be excluded, as will those who have had previous chemotherapy or radiation treatment. Patients may receive standard nutritional care, as needed.
