Effect of human papilloma virus infection status on the prognosis of localized stage head and neck squamous cell carcinomas in different ethnic groups of Xinjiang / 中华口腔医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To discuss the effect of limited head and neck squamous cell carcinomas human papillomavirus(HPV) infection status on the prognosis in different nationalities of Xinjiang.</p><p><b>METHODS</b>The clinical data of 149 cases of head and neck squamous cell carcinoma from Uighur, Han and Kazak was analyzed. The HPV16/18 infection and viral load was examined.The prognosis was analyzed by cox multiIvar-Iate model. The effect of HPV infection status on prognosis was evaluated.</p><p><b>RESULTS</b>In this study, Oropharyngeal HPV infection rate was 35.0%, followed by hypopharynx 30.0%, oropharyx was 16.0%. The overall survival rate of 3 years and 5 years was 66.4%, and 39.2% respectively. The clinical stage,N stage and HPV were influencing factors for the prognosis of patients with head and neck squamous cell carcinoma (P< 0.05). N stage and HPV were independent prognostic factors for the prognosis of patients with head and neck squamous cell carcinoma (P< 0.05).</p><p><b>CONCLUSIONS</b>There is a high rate of HPV infection in oropharynx in head and neck cancer. HPV positive is a protective factor for the prognosis of head and neck cancer, and the risk of death in patients with HPV was 3/5 lower than that of HPV negative patients. HPV viral load may be positively related to the total survival rate. N stage is a risk factor for the prognosis of head and neck cancer. Different nationalities have little influence on prognosis.</p>
