To identify the gaps of knowledge and highlight the challenges and opportunities for controlling cervical cancer in sub-Saharan Africa (SSA).
A comprehensive review of peer-reviewed literature to summarize the epidemiological data on human papillomavirus (HPV) and invasive cervical cancer (ICC) by HIV status, to review feasible and effective cervical screening strategies, and to identify barriers in the introduction of HPV vaccination in SSA.
ICC incidence in SSA is one of the highest in the world with an age-standardized incidence rate of 31.0 per 100,000 women. The prevalence of HPV16/18, the two vaccine preventable-types, among women with ICC, does not appear to differ by HIV status on a small case series. However, there are limited data on the role of HIV in the natural history of HPV infection in SSA. Cervical screening coverage ranges from 2.0% to 20.2% in urban areas and 0.4% to 14.0% in rural areas. There are few large scale initiatives to introduce population-based screening using cytology, visual inspection or HPV testing. Only one vaccine safety and immunogenicity study is being conducted in Senegal and Tanzania. Few data are available on vaccine acceptability, health systems preparedness and vaccine cost-effectiveness and long-term impact.
Additional data are needed to strengthen ICC as a public health priority to introduce, implement and sustain effective cervical cancer control in Africa.
确定知识差距,突出撒哈拉以南非洲(SSA)地区宫颈癌防控面临的挑战与机遇。
全面回顾同行评议文献,以总结按艾滋病毒感染状况划分的人乳头瘤病毒(HPV)和浸润性宫颈癌(ICC)的流行病学数据,审查可行且有效的宫颈癌筛查策略,并确定在SSA地区引入HPV疫苗接种的障碍。
SSA地区的ICC发病率是世界上最高的之一,年龄标准化发病率为每10万名女性中有31.0例。在一个小病例系列中,ICC女性中两种可通过疫苗预防的HPV16/18型的流行率似乎不因艾滋病毒感染状况而异。然而,关于艾滋病毒在SSA地区HPV感染自然史中的作用的数据有限。城市地区的宫颈癌筛查覆盖率在2.0%至20.2%之间,农村地区为0.4%至14.0%。很少有大规模举措采用细胞学、视觉检查或HPV检测开展基于人群的筛查。塞内加尔和坦桑尼亚仅开展了一项疫苗安全性和免疫原性研究。关于疫苗可接受性、卫生系统准备情况以及疫苗成本效益和长期影响的数据很少。
需要更多数据,以将ICC作为公共卫生重点,在非洲引入、实施并维持有效的宫颈癌防控。
