Abstract

The three most important prognostic factors in patients with head and neck squamous cell carcinoma (HNSCC) are tumor size, nodular histological condition and tumor origin. Recently, human papilloma virus (HPV), particularly HPV-16, has been acknowledged as a prognostic factor. HPV+ patients have better survival than HPV-. This has created a controversy because other factors may influence the prognosis. The objective of this study was to investigate whether HPV has prognostic value in patients with HNSCC. We carried out a retrospective evaluation of patients with HNSCC and the following variables were analyzed: survival, tumor location, stage, general condition according to Eastern Cooperative Oncology Group (ECOG) status, treatment and HPV association identified by PCR. We used a descriptive analysis of simple frequencies and central tendency and dispersion measures according to the type of variables. We used descriptive analysis for overall survival with Kaplan- Meier and Cox regression with 95% confidence interval. There were 179 patients included: 119 (66.5%) were male. Average age of patients was 64 years; 34% of the tumors were located in the oral cavity and 33% were located in the larynx. Factors associated with survival ...Continue Reading
