Cervical cancer (CC) remains a current global issue, with >90% of cervical cancer cases being attributed to human papilloma virus (HPV). The highest burden of cervical cancer is reported in resource-depleted geographical areas with a high incidence of HPV infection. Recent developments in primary prevention include vaccinations against specific strains of HPV and the psychoeducation of the public. Yet, despite the availability of vaccinations, there is high incidence of both HPV and cervical cancer in developing countries, which is attributed to a multitude of barriers including inaccessibility to expensive vaccines. With regards to secondary prevention, progress is actively being made to develop more effective methods of screening and to specifically address the needs of low-income countries. In the past few years, more novel screening methods, such as self-assessment kits, immunohistochemistry and methylation marker analysis, have been developed. Barriers to screening in resource-depleted countries include limited financial resources and infrastructure to develop screening programmes, a lack of screening programmes that are accessible to populations, inadequate training of healthcare teams and stigma related to medical examinations performed as part of screening. Developing primary and secondary prevention programs, as well as addressing the barriers involved in countries with low socioeconomic levels, can drastically reduce morbidity and mortality rates associated with cervical cancer, thus reducing the burden associated with this gynaecological malignancy.
宫颈癌(CC)仍然是当前一个全球性问题,超过90%的宫颈癌病例归因于人乳头瘤病毒(HPV)。据报道,在HPV感染高发的资源匮乏地理区域,宫颈癌负担最重。一级预防的最新进展包括针对特定HPV毒株的疫苗接种以及公众的心理教育。然而,尽管有疫苗可用,但发展中国家的HPV和宫颈癌发病率仍然很高,这归因于多种障碍,包括难以获得昂贵的疫苗。在二级预防方面,正在积极取得进展,以开发更有效的筛查方法,并专门满足低收入国家的需求。在过去几年中,已经开发出了更多新颖的筛查方法,如自我评估试剂盒、免疫组织化学和甲基化标志物分析。资源匮乏国家筛查的障碍包括开展筛查项目的财政资源和基础设施有限、缺乏可供人群使用的筛查项目、医疗团队培训不足以及与作为筛查一部分进行的医学检查相关的耻辱感。制定一级和二级预防计划,以及解决社会经济水平较低国家所涉及的障碍,可以大幅降低与宫颈癌相关的发病率和死亡率,从而减轻与这种妇科恶性肿瘤相关的负担。
