Head and neck cancer, the sixth most common cancer worldwide, account for about 1 out of 20 malignant tumors. In recent years a reduction in the incidence of cervical cancer, but a concomitant major increase in the incidence of HPV-mediated oropharyngeal cancer caused by orogenital HPV transmission has been observed. Consequently, in wealthy countries oropharyngeal squamous-cell carcinomas (OPSCC) is now the most frequent HPV-related cancer, having overtaken cervical cancer. Without effective medical interventions, this incidence trend could continue for decades. As no specific precursor lesion has been consistently identified in the oral cavity and oropharynx, HPV vaccination is the logical intervention to successfully counteract also the rising incidence of OPSCCs. However, HPV vaccine uptake remains suboptimal, particularly in males, the population at higher risk of OPSCC. Alternative primary prevention measures, such as modifications in sexual behaviors, could be implemented based on knowledge of individual genital HPV status. Until recently, this information was not available at a population level, but the current gradual shift from cytology (Pap test) to primary HPV testing for cervical cancer screening is revealing the presence of oncogenic viral genotypes in millions of women. In the past, health authorities and professional organizations have not consistently recommended modifications in sexual behaviors to be adopted when a persistent high-risk HPV cervicovaginal infection was identified. However, given the above changing epidemiologic scenario and the recent availability of an immense amount of novel information on genital HPV infection, it is unclear whether patient counseling should change. The right of future partners to be informed of the risk could also be considered. However, any modification of the provided counseling should be based also on the actual likelihood of a beneficial effect on the incidence of HPV-associated oropharyngeal cancers. The risk is on one side to induce unjustified anxiety and provide ineffective instructions, on the other side to miss the opportunity to limit the spread of oral HPV infections. Thus, major health authorities and international gynecologic scientific societies should issue or update specific recommendations, also with the aim of preventing inconsistent health care professionals' behaviors.
头颈部癌症是全球第六大常见癌症,约占恶性肿瘤的 1/20。近年来,宫颈癌的发病率有所下降,但与此同时,由于口咽 HPV 传播导致的 HPV 介导的口咽癌的发病率却显著增加。因此,在富裕国家,口咽鳞状细胞癌(OPSCC)现在是最常见的 HPV 相关癌症,已经超过了宫颈癌。如果没有有效的医疗干预,这种发病趋势可能会持续几十年。由于在口腔和口咽中尚未始终如一地确定特定的前驱病变,因此 HPV 疫苗接种是成功对抗 OPSCC 发病率上升的合理干预措施。然而,HPV 疫苗接种率仍然不理想,尤其是在男性中,他们是 OPSCC 高危人群。可以根据个体生殖器 HPV 状况的知识,实施 HPV 疫苗接种以外的其他初级预防措施。直到最近,由于人口水平上无法获得这些信息,但目前宫颈癌筛查正从细胞学(巴氏试验)逐渐转向 HPV 初筛,这揭示了数以百万计的女性存在致癌病毒基因型。过去,卫生当局和专业组织并没有一致建议在持续高危 HPV 宫颈感染时改变性行为。然而,鉴于上述不断变化的流行病学情况以及最近大量关于生殖器 HPV 感染的新信息,尚不清楚是否应该改变患者咨询。还可以考虑告知未来伴侣存在风险的权利。但是,任何提供咨询的修改都应基于对 HPV 相关口咽癌发病率产生有益影响的实际可能性。一方面,风险在于引起不必要的焦虑和提供无效的指导,另一方面则是错失限制口腔 HPV 感染传播的机会。因此,主要的卫生当局和国际妇科科学协会应该发布或更新具体建议,旨在防止卫生保健专业人员行为的不一致。
