title: [Human papillomavirus in squamous cell cancer of the head and neck. A study at the Ulm Military Hospital, Germany].
abstract: There is increasing evidence worldwide that human papillomavirus is a major risk factor for head and neck cancer. Only few studies on this association have been performed in Germany to date. For the purposes of the present study, tumor specimens from 223 patients with squamous cell cancer of the oral cavity, oropharynx, hypopharynx and larynx were analyzed for HPV DNA and p16INK4a expression. The prevalence of HPV genotype 16 (HPV16) DNA in the study population was 17.5%. Further high-risk HPV types were not detected. All HPV16-positive tumors showed intense p16INK4a expression. HPV16 prevalence was highest in tonsillar carcinoma (37.5%) and lowest in laryngeal cancer (2.8%). We observed a significantly higher incidence of cervical lymph node metastases in patients with HPV16-positive tonsillar carcinoma in comparison to HPV-negative tumors (p < 0.016). Tobacco and/or alcohol consumption was significantly lower in patients with HPV-positive tumors (p < 0.0001).
