Abstract
Background and Objectives
High risk HPV is associated with oropharyngeal SCC (OSCC) and is responsible for the increasing incidence of this cancer type among younger patients.
Patients with HPV positive oropharyngeal SCC have a better prognosis when compared with HPV negative, tobacco induced SCC.
HPV E6 inactivates p53 leading to low expression of p53; tobacco induced oropharyngeal SCC is characterized by p53 overexpression, resistance to treatment and poor prognosis. However, in many cases of HPV OSCC, there is a history of current or remote smoking, making this disease a multifactorial process. We expect that smoking will influence the level of p53 expression in HPV positive smokers.
The objective of our study is to evaluate the differences in p53 expression in HPV positive and HPV negative patients, smokers and nonsmokers.
