The studies exploring the relationship between HPV infection and laryngealcarcinoma began in 1980s,since then,almost all the research was aimed at theinvestigation of the HPV prevalence in the biopsies,due to differences in thechoice of DNA detection method,cell sampling and the geogen,the prevalenceestimates of HPV have varied accordingly,and led to two different points about therelationship between HPV infection and laryngeal carcinoma:some researchersdemonstrated that a higher HPV prevalence could be found in laryngeal carcinomas(from 50% to 90%)than in benign laryngeal lesions,suggesting a relationshipbetween HPV infection and laryngeal carcinoma;but the other researchers foundthat the isolation of HPV is no greater in the laryngeal cancers(from 5% to 43.3%)than in the normal larynx or benign laryngeal lesions,thereby questioning itsctiological significance,so,the role of HPV in the development of laryngealcarcinomas still remains unclear.

有关HPV与喉癌的研究始于80年代，但20多年来研究模式始终停留在对临床标本进行检测的水平上，由于各家采用的检测手段敏感性不同、标本数量以及来源地域也存在差异，使各家学者对喉癌中HPV阳性率的报道极不一致，并由此导致了两种截然不同的观点：一部分学者报告的喉癌标本中HPV阳性率高达50%~90%，并显著高于喉良性肿瘤，认为HPV与喉癌有关；而另有不少学者检测的样本中，阳性率（5%~43.3%）并不比正常喉粘膜及良性肿瘤高，认为HPV与喉癌无关，因此，HPV到底是不是喉癌的致癌因素目前仍无定论。
