## Abstract The role of the immune system in the pathogenesis and treatment of cancer is currently a popular area of research. An underlying fundamental concept of cancer immunology is the supposition that tumor cells express antigens differently than normal cells, both qualitatively and quantitati

β¦ Synopsis
Patients with head and neck cancer have immune impairment, demonstrable at several levels, often related t o the clinical tumor stage. Researchers have focused on this unique system to understand locoregional cancer biology and to develop new therapeutic strategies. Along with classic cellular immunology, which has already resulted in several new theories and therapies, recent molecular biologic data are providing stimulating insights into cancer immunology and the larger field of tumor-host interactions.
CELLULAR IMMUNOLOGY
Deficits of Cellular Function in the Head and Neck
Tumor Model. Host immune response against a tumor is heterogeneous. The various immune mechanisms involved include effector cells, their target structures, and regulatory elements. With appropriate orchestration, two main mechanisms of antitumor control normally exist: the natural killer (NK) nonspecific response and the specific response that is dependent on antigen presentation by the molecules of the major histocompatibility complex (MHC).
In head and neck cancer, deficits of the NK

## Abstract ## Background. The aim of this study was to systematically analyze outcome measures in head and neck cancer trials using the International Classification of Functioning. Disability, and Health (ICF) as reference. ## Methods. Clinical trials 2000 to 2006 in MEDLINE were selected accor
Rhenium-186 based radioimmunotherapy (RIT) may have potential for the treatment of minimal residual disease in patients with squamous cell carcinoma of head and neck (HNSCC). In an effort to enhance the efficacy of RIT, we evaluated the combination of RIT and anti-epidermal growth factor receptor (E
Background. Angiogenesis is crucial for tumor growth and metastasis. In several tumors, microvascular density has been shown to correlate with metastasis and aggressiveness. Basic fibroblast growth factor (bFGF) has potent angiogenic activity and has been identified in a wide variety of malignancies
