ABSTRACT
<p><b>OBJECTIVE</b>To detect the infection of human papillomavirus (HPV) 16/18 in patients with head and neck squamous cell carcinoma and explore the relationship between HPV infection and expressions of Ki-67 and P53 proteins in tumor tissue.</p><p><b>METHOD</b>The level of HPV 16/18 DNA was measured by real time polymerase chain reaction, and Ki-67 and P53 proteins were measured by immunohistochemistry in tissues from head and neck squamous cell carcinoma.</p><p><b>RESULTS</b>HPV 16/18 DNA was detected in 62.8% of our patients. In each cancer tissue sample, Ki-67 protein was expressed between 2% to 70%. P53 protein was expressed in 46.15% of our patients. No significant relation was found between HPV 16/18 DNA level and sex, smoking, drinking, and tumor clinical stages. However, level of HPV 16/18 DNA was found to have positive relation with tumor pathological grades and negative relation with P53 protein expression. No relation with Ki-67 protein expression was found.</p><p><b>CONCLUSION</b>Head and neck squamous cell carcinoma may be initiated by HPV 16/18 infection and the mechanism in carcinogenesis involves abnormal expression in P53 protein.</p>
