Popis: | The aim of the study was to investigate prevalence of high-risk human papillomavirus (HR-HPV) infection in sinonasal carcinomas by immunohistochemistry, in situ hybridization, and polymerase chain reaction, detecting p16INK4a protein (p16) expression and presence of both HPV DNA and HPV E6/E7 messenger RNA (mRNA). The study comprised 47 males and 26 females, aged 23–83 years (median 62 years), mostly (67 %) with a squamous cell carcinoma (SCC). Of the tumors, 53 % arose in the nasal cavity, 42 % in the maxillary sinus, and 5 % in the ethmoid complex. The follow-up period ranged 1–241 months (median 19 months). HPV16, HPV18, or HPV35 were detected in 18/73 (25 %) tumors, 17 SCCs, and 1 small cell neuroendocrine carcinoma. There was a strong correlation between results of HPV detection methods and p16 expression (p |
