Abstract:
Objective To explore the role of HPV16 and p53 protein in the pathogenesis of tumors of nasal cavity and sinus of Chinese people. Methods The expression of HPV16 and p53 in 58 tumor samples of nasal cavity and sinus was detected by immunohistochemistry. Results There was no p53 expression in inverted pipillomas(IP). HPV16 infection rate in IP was 62.5%. The positive rate of p53 protein in the malignant tumors and IP with atypical hyperplasia was 56.0% and 44.4%, respectively, and HPV16 infection rate in the both tissues was 24.0% and 66.7%, respectively. The positive rate of p53 and HPV16 simultaneous expression in IP with atypical hyperplasia were 33.3%, which was higher than that in the malignant tumors and IP without atypical hyperplasia. Conclusion The high-risk HPV16 infection may be primary cause of IP. p53 gene mutation may be close relation with the pathogenesis of nasal cavity and sinus malignant tumors. HPV16 and p53 may have synergic effect in the malignant transformation of nasal cavity and sinus benign tumors.
