RESUMO
Objective:To evaluate the role of HPV16E6,cyclin D1,and human telomerase transcriptase(hTERT) in the development and progression of nasopharyngeal carcinoma(NPC) and to discuss the clinical significance.Methods: Immunohistochemistry was used to detect the expression of HPV16E6,cyclin D1,and hTERT in paraffin-embedded nasopharyngeal carcinoma tissues and nasopharyngeal chronic inflammation tissues.The relationship between their expression with the clinicopathological features of NPC was analyzed;the influence of their expression on prognoses of patients was also analyzed.Results: The positive rates of HPV16E6,cyclin D1,and hTERT in NPC tissues were 62.5%(35/56),50.0%(28/56),and 67.9%(38/56),respectively,which were significantly higher than those in the inflammation tissues(P0.05).HPV16E6 expression was positively correlated with cyclin D1(r=0.480,P
