There is a continuing need to monitor and evaluate the impact of organized screening programmes on cancer incidence and mortality. We report results from a programme assessment conducted within the International Cancer Screening Network (ICSN) to understand the characteristics of cervical screening programmes within countries that have established population-based breast cancer screening programmes.
In 2007-2008, we asked 26 ICSN country representatives to complete a web-based survey that included questions on breast and cervical cancer screening programmes. We summarized information from 16 countries with both types of organized programmes.
In 63% of these countries, the organization of the cervical cancer screening programme was similar to that of the breast cancer screening programme in the same country. There were differences in programme characteristics, including year established (1962-2003 cervical; 1986-2002 breast) and ages covered (15-70+ cervical; 40-75+ breast). Adoption of new screening technologies was evident (44% liquid-based Pap tests; 13% human papillomavirus (HPV)-triage tests cervical; 56% digital mammography breast). There was wide variation in participation rates for both programme types (<4-80% cervical; 12-88% breast), and participation rates tended to be higher for cervical (70-80%) than for breast (60-70%) cancer screening programmes. Eleven ICSN member countries had approved the HPV vaccine and five more were considering its use in their organized programmes.
Overall, there were similarities and differences in the organization of breast and cervical cancer screening programmes among ICSN countries. This assessment can assist established and new screening programmes in understanding the organization and structure of cancer screening programmes.
持续监测和评估有组织的筛查计划对癌症发病率和死亡率的影响非常重要。我们报告了国际癌症筛查网络(ICSN)内部进行的一项计划评估的结果,以了解已建立基于人群的乳腺癌筛查计划的国家中宫颈癌筛查计划的特点。
在 2007-2008 年,我们要求 26 名 ICSN 国家代表完成一项基于网络的调查,其中包括有关乳腺癌和宫颈癌筛查计划的问题。我们总结了来自 16 个同时具有这两种有组织计划的国家的信息。
在这些国家中,63%的国家宫颈癌筛查计划的组织形式与本国的乳腺癌筛查计划相似。在计划特征方面存在差异,包括建立年份(宫颈癌为 1962-2003 年;乳腺癌为 1986-2002 年)和涵盖年龄(宫颈癌为 15-70+岁;乳腺癌为 40-75+岁)。新筛查技术的采用显而易见(44%采用液基巴氏涂片检查;13%采用人乳头瘤病毒(HPV)筛查试验检查宫颈癌;56%采用数字乳房摄影术检查乳腺癌)。两种类型的计划参与率差异很大(宫颈癌为<4-80%;乳腺癌为 12-88%),而且宫颈癌(70-80%)筛查计划的参与率往往高于乳腺癌(60-70%)筛查计划。11 个 ICSN 成员国已批准使用 HPV 疫苗,还有五个成员国正在考虑在其有组织的计划中使用该疫苗。
总体而言,ICSN 国家中乳腺癌和宫颈癌筛查计划的组织形式既有相似之处,也有不同之处。该评估可以帮助已建立的和新的筛查计划了解癌症筛查计划的组织和结构。
