Hospital based cytology screening is one of the suggested alternative strategies for the developing countries. The present communication attempts to estimate the reduction in lifetime risk of cervical cancer initiated through a hospital based single lifetime screening programme. The percent reduction in cumulative incidence of cervical cancer during lifetime in different age groups of women was calculated after estimating the number of incident cases in the absence as well as presence of screening. Our analysis revealed that by introducing the single life time cytology screening in the group of hospital attending population, an overall reduction in the cumulative incidence of cervical cancer during lifetime was found to be 10.2%. It was further estimated that the reduction was much less in the early age groups (2.4-10.2% in 20-34 years) as compared to later age groups (11.2-55.6% in 35+ years).
基于医院的细胞学筛查是发展中国家建议采用的替代策略之一。本通讯试图估算通过基于医院的单次终身筛查计划引发的宫颈癌终身风险降低情况。在估算有无筛查情况下的发病例数后，计算了不同年龄组女性一生中宫颈癌累积发病率的降低百分比。我们的分析表明，在就诊人群组中引入单次终身细胞学筛查后，发现宫颈癌终身累积发病率总体降低了10.2%。进一步估计，与年龄较大组（35岁及以上为11.2 - 55.6%）相比，年龄较小组（20 - 34岁为2.4 - 10.2%）的降低幅度要小得多。
