外耳道乳头状瘤中的人乳头瘤病毒检测及其临床意义

目的外耳道乳头状瘤(papilloma of the external auditory canal,PEAC)发病率占外耳道良性肿瘤的第1位。文中探讨人乳头瘤病毒(human papilloma virus,HPV)在PEAC发病中的作用及HPV检测在PEAC中的意义。方法观察45例PEAC中挖空细胞及异型增生的组织形态学变化,并采用原位杂交技术分别检测HPV低危型(6/11)DNA,HPV高危型(16/18)DNA。结果PEAC不伴挖空细胞、PEAC伴挖空细胞、PEAC伴挖空细胞同时伴异型增生组织中HPV低危型(6/11)DNA感染率分别为16.7%、80.6%、66.7%,三者间差异有统计学意义(P<0.05);HPV高危型(16/18)DNA感染率分别为0%、16.7%、66.7%,三者间差异有统计学意义(P<0.05)。HPV低危型(6/11)DNA的检出率与性别有关(P<0.05)。结论HPV感染是PEAC致病的重要因素,积极开展抗HPV感染的治疗对减低PEAC的发病,防止其复发及癌变均具有重要的意义。

Detection of human papilloma virus in papilloma of the external auditory canal and its clinical significance

Objective The incidence of papilloma of the external auditory canal (PEAC) ranks the first among the benign tumors of the external auditory. This study aimed to evaluate the role of human papilloma virus (HPV) infection in the pathogenesis of PEAC and the significance of HPV detection in the treatment of the disease. Methods We observed the histomorphological changes of koilocytes and their dysplasia in 45 cases of PEAC and detected HPV 6/11 DNA and HPV 16/18 DNA using the in situ hybridization (ISH) techni...
