Abstract
Purpose
To report the incidence of HPV-related oropharyngeal cancer (OC) in our region, and determine the influence of HPV status on survival among patients treated with chemoradiation (CRT).
Methods
A total of 102 patients with stage II–IV OC treated by CRT at four hospitals in Madrid, Spain were retrospectively reviewed. Immunohistochemistry analysis was performed to evaluate p16 expression in pretreatment tumor block samples obtained from these patients. HPV-positive and HPV-negative patients were compared to assess differences in overall survival (OS), loco-regional control and disease-free survival.
Results
Of the tumor samples evaluated, 26.7 % were p16 positive. HPV-positive patients were younger (median age, 56 vs 59 years; p = 0.052). No significant differences were observed in terms of tumor stage, gender, or smoking habit between HPV+ and HPV− patients. HPV+ patients showed a trend towards better OS (67.4, vs 49.7 %; hazard ratio, 0.55; p = 0.095).
Conclusions
Incidence of HPV-related OC in our region is similar to that reported in other regions in Europe, yet lower than in North America. We observed a trend for improved OS in patients with HPV+ oropharyngeal cancer.
