Slide 2-

What is head and neck cancer? Head and Neck Cancer is a group of cancers that includes tumors in several areas above the collar bone.
Slide 3-

Head and Neck Cancer has three major subdivisions: Oral Cancer Laryngeal Cancer Nasopharyngeal Cancer.
Slide 4-

Head and Neck Cancer Squamous cell carcinoma of the head and neck (SCCHN) occurs in 50,000 new cases annually in the US, resulting in over 13,000 deaths each year
Slide 5-

Risk Factors for Head and Neck Cancer Tobacco Products: Smoking Tobacco Cigarettes Cigars Pipes Chewing Tobacco Snuff Ethanol Products Chemicals: Asbestos Chromium Nickel Arsenic Formaldehyde Other Factors: Ionizing Radiation Plummer-Vinson Syndrome Epstein-Barr Virus Human Papilloma Virus
Slide 6-

Possible Occupational Risks for Head and Neck Cancer Woodworking Leather manufacturing Nickel refining Textile industry Radium dial painting
Slide 7-

Warning Signs of Head and Neck Cancer Hoarseness Erythroplasia Referred otalgia Persistent sore throat Epistaxis Nasal obstruction Serous otitis media Neck mass Non-healing ulcer Dysphagia Submucosal mass Not all cancers present with symptoms at early stages!
Slide 8-

Factors Delaying the Diagnosis of Head and Neck Cancers Patient procrastination in seeking medical attention Physician delay in diagnosis Patient remains asymptomatic for a prolonged period
Slide 9-

Five-Year Survival Rate for Oral Cavity and Pharynx Cancer Stage at Diagnosis
Slide 10-

Concentrations of 60 cytokines, growth factors, and tumor antigens were measured in the sera of 116 SCCHN patients prior to treatment (active disease group), 103 patients who were successfully treated (no evidence of disease, NED, group), and 117 smoker controls without evidence of cancer.

Biomarkers utilized in this study
Slide 13-

Projection Pursuit Technique
Slide 14-

Head and Neck Cancer (ROC curve) Classification of head and neck cancer (n=116) vs. no evidence of disease group (n=103), and healthy smokers control utilizing the 25-marker panel. Cross-validation test, 55/45 random split, 100 runs.
Slide 15-

Sensitivity refers to the fraction of patients with the disease correctly identified as positive by the test. Specificity refers to the fraction of patients without the disease correctly identified as negative by the test.
Slide 16-

The multi-marker panel offering the highest diagnostic power was comprised of 25 biomarkers, including: EGF, EGFR, IL-8, tPAI-1, AFP, MMP-2, MMP-3, IFN-, IFN-, IP-10, RANTES, MIP-1, IL-7, IL-17, IL-1R, IL-2R, G-CSF, mesothelin, IGFBP-1, E-selectin, cytokeratin (CK)19, V-CAM, and CA-125.
Slide 17-

Head and Neck Cancer Link to chronic infection HPV Epstein Barr virus
Slide 18-

Human Papillomavirus (HPV) DNA virus Preferentially infect squamous epithelial cells >100 genotypes ≥40 genital HPV types
Slide 19-

Epidemiology of HPV The most common STD worldwide 80% sexually active adults in the US infected with at least one HPV type by age 501 Peak prevalence during adolescence and young adulthood Prevalence declines with age HPV 16 is the most common HR type 1.
