J Natl Cancer I:针对接种过HPV疫苗的女性的更佳宫颈癌筛查方案!

2017-03-07 luowenbo MedSci原创

目前美国宫颈癌筛查指南尚未推出针对接种过HPV疫苗女性的宫颈癌筛查推荐,但接种过HPV疫苗的女性与未接种过HPV疫苗的女性相比,其宫颈癌筛查方案应该加以调整。

目前美国宫颈癌筛查指南尚未推出针对接种过HPV疫苗女性的宫颈癌筛查推荐,但接种过HPV疫苗的女性与未接种过HPV疫苗的女性相比,其宫颈癌筛查方案应该加以调整。

根据美国女性HPV与宫颈癌发生发展特点,建立数学模型,通过该模型来反应接种过二价、四价、九价HPV疫苗的美国女性,在采用不同的宫颈癌筛查方案时,其健康收益、健康成本和检查所致损伤的变化。从一级筛查试验(如:宫颈细胞学检查、HPV检查、宫颈细胞学联合HPV检查)、筛查起始年龄和/或开始一项新的筛查项目的年龄、常规筛查的间隔时间这三种指标来设定不同的宫颈癌筛查方案。从社会价值角度对不同的宫颈癌筛查方案进行成本-效益分析,即若一个宫颈癌筛查方案的成本效益比值在5万至20万美元每质量调整生命年(QALY),则认为该宫颈癌筛查方案具有好的成本效益比。

对于全程充分接种HPV的二价或四价疫苗的美国女性来说,最佳筛查方案是:25岁或30岁开始每五年进行一次宫颈细胞学检查或者HPV检测,成本效益比在34680至138560美元每质量调整生命年。将筛查年龄提前或者筛查频率增加会增加成本效益比。接种九价疫苗的女性,单用HPV检测作为筛查指标就已足够,同时应减少筛查频率(如:每十年一次),且开始筛查的年龄可以推后至35岁(40210美元每质量调整生命年)或30岁(127010美元每质量调整生命年),接种相对低效的九价HPV疫苗的女性,从25岁或30岁开始进行每十年一次的HPV筛查最佳。值得关注的是,现行美国宫颈癌筛查指南并不适用于HPV接种过的女性。

该数学研究模型表明,与美国现行宫颈癌筛查指南相比,接种过HPV疫苗的女性的宫颈癌筛查方案,应该推后筛查起始年龄,降低筛查频率,采用一级筛查方法,在保证健康效益的同时尽量避免筛查带来的身体伤害和降低筛查成本支出。
