Abstract: The present disclosure relates to a panel of biomarkers for the detection/diagnosis and prognosis of head and neck squamous cell carcinoma (HNSCC). Biomarkers for the detection/diagnosis of carcinoma cells identified by proteomic profiling and, detection/identification of selected proteins that are differentially regulated, in a biological sample from an individual as candidate markers. The biomarkers are useful for non-invasive early detection/prognosis focusing on the protein profiling of saliva at different stages of oral pre-cancer and cancer progression. Furthermore, the present invention deals with novel methods of diagnosing and for providing a prognosis for oral cancer and periodontal disease. In addition, the invention also provides kits that are useful for the practice of the methods of the invention.

Abstract: Systematic comparisons of samples of adjacent clinically non malignant and tumor tissue from cancer of the gingivo buccal complex obtained during surgical resection of the tumor revealed significant differences in protein expression between the cancer tissue and the adjacent clinically non malignant tissue in each patient. This study has identified a set of new proteins which can differentiate between the epithelial tissue from cancer patients which may be useful for high-through put early detection, prognosis, and potential targets for therapy.

Abstract: The present invention relates to identification of a set of proteins, which elicit an autoantibody response in patients with cancer of gingivo-buccal complex. Systematic comparisons of serum samples from clinically normal individuals and from patients with cancer of gingivo-buccal complex has revealed significant differences in the presence of autoantibodies in sera against cellular antigens present in a cancer cell line. The autoantibody response to a single or combination of these protein antigens serves as a novel marker and can be utilized for screening, early detection, prognosis, and potential target for therapy. The invention also provides for the use of the identified protein antigens in immunoassays designed to detect the presence of serum antibodies to the specific protein antigens in sera from individuals that harbor such antibodies. The invention also relates to the use of the identified antigens as immunogens for stimulation of an immune response in patients expressing such protein antigens.
