MedicalResearch.com: What is the background for this study?
Response: Head and neck cancer involves cancers of the oral cavity, oropharynx and larynx. It is difficult to treat. Part of the challenge is that it is distinguishing the patients with tumors that are going to behave aggressively from those with less aggressive disease. As a result, many patients undergo treatment that may be more intensive and morbid than they need while others need more aggressive treatment. Tissue markers associated with prognosis may be able to help clinicians differentiate patients who need more aggressive treatment from those whose treatment can be less intensive. CD44 is a cell surface glycoprotein and tumor-initiating marker. CD44 and another surface protein, EGFR, are involved in tumor extension and are associated with poor prognosis. Certain forms of Human Papillomavirus (HPV) are known to cause oropharyngeal cancer and are associated with a good prognosis. P16 is a surrogate marker for the kind of HPV that causes cancer. Understanding the relationships between how these markers are expressed in cancer tissue may direct patient treatment in the future.
