Human papillomavirus (HPV)-related screening technologies and HPV vaccination offer enormous potential for cancer prevention, notably prevention of cervical cancer. The effectiveness of these approaches is, however, suboptimal owing to limited implementation of screening programmes and restricted indications for HPV vaccination. Trials of HPV vaccination in women aged up to 55 years have shown almost 90% protection from cervical precancer caused by HPV16/18 among HPV16/18-DNA-negative women. We propose extending routine vaccination programmes to women of up to 30 years of age (and to the 45-50-year age groups in some settings), paired with at least one HPV-screening test at age 30 years or older. Expanding the indications for HPV vaccination and much greater use of HPV testing in screening programmes has the potential to accelerate the decline in cervical cancer incidence. Such a combined protocol would represent an attractive approach for many health-care systems, in particular, countries in Central and Eastern Europe, Latin America, Asia, and some more-developed parts of Africa. The role of vaccination in women aged >30 years and the optimal number of HPV-screening tests required in vaccinated women remain important research issues. Cost-effectiveness models will help determine the optimal combination of HPV vaccination and screening in public health programmes, and to estimate the effects of such approaches in different populations.
人乳头瘤病毒(HPV)相关的筛查技术和 HPV 疫苗接种为癌症预防,特别是宫颈癌预防带来了巨大的潜力。然而,由于筛查计划的实施有限以及 HPV 疫苗接种的适应证受限,这些方法的效果并不理想。在年龄在 55 岁以下的女性中进行 HPV 疫苗接种试验表明,在 HPV16/18-DNA 阴性的女性中,HPV16/18 疫苗接种几乎可预防 90%的宫颈癌前病变。我们建议将常规疫苗接种计划扩大到年龄最大为 30 岁的女性(并在某些情况下扩大到 45-50 岁年龄组),同时在 30 岁或以上的年龄至少进行一次 HPV 筛查检测。扩大 HPV 疫苗接种的适应证,并在筛查计划中更广泛地使用 HPV 检测,有可能加速宫颈癌发病率的下降。这种联合方案对许多医疗保健系统来说都是一种有吸引力的方法,特别是中欧和东欧、拉丁美洲、亚洲以及一些较发达的非洲国家。疫苗接种在 30 岁以上的女性中的作用以及接种女性所需的 HPV 筛查检测的最佳数量仍然是重要的研究问题。成本效益模型将有助于确定 HPV 疫苗接种和筛查在公共卫生计划中的最佳组合,并估计这些方法在不同人群中的效果。
