[Detection of Epstein-Barr virus and human papillomavirus in sinonasal malignant neoplasms].

ABSTRACT

OBJECTIVE: To investigate the existance of Epstein-Barr virus (EBV) and papilloma virus(HPV) in sinonasal malignant neoplasms. METHOD: EBV and HPV (including HPV6,11,16,18,33) gene were detected in paraffin-embedded tissues with polymerase chain reaction(PCR) from 32 cases of sinonasal malignant neoplasms. RESULT: EBV was detected in 12(37.5%), HPV in 21(65.6%); The coinfection of EBV and HPV was found in 6 cases with stage III-IV by TNM; 10 cases of nasal polyps contained neither EBV nor HPV. CONCLUSION: Like HPV, there may be relationship between EBV and sinonasal malignant neoplasms. The coinfection of EBV and HPV is related to stage III-IV by TNM of sinonasal malignant neoplasms.
