EBCOG position statement: Gender neutral HPV vaccination for young adults

Provision of screening services for cervical and breast cancer - A scientific study commissioned by the European Board & College of Obstetrics and Gynaecology (EBCOG)

OBJECTIVE

Cancer screening can play an important role in early detection, improving treatment outcomes and reducing morbidity and mortality. Breast and cervical cancers belong to the most common gynaecological cancers group. Countries provide different screening programmes on its eligible population basis centred on different health care policies. This scientific study aims to assess and understand the health inequalities in the member countries of the European Board & College of Obstetrics and Gynaecology (EBCOG) as regards screening programmes of gynaecological cancer, with a special focus on breast and cervical cancers' screening strategies.

STUDY DESIGN

A descriptive questionnaire-based study was conducted, addressed to EBCOG member countries.

RESULTS

Ninety-one percent of the countries have an organized national or regional screening programme for cervical cancer. Of these, 45% of countries use both cytology and testing for Human Papilloma Virus (HPV) as screening test, 31% use cytology exclusively and 17% only perform HPV testing. Considerable differences were found regarding the interval of screening test: there are countries performing HPV detection triennially, while others perform only conventional cytology every 5 years. Sixty-nine percent of countries included in this study begin screening for cervical cancer in women aged 25 to 29 years, four of them using HPV detection as the screening test. Six countries begin cervical cancer screening before the age of 25. As regards vaccination against HPV, almost all countries have implemented national HPV vaccination programme, except in Poland and Turkey. The 9-valent HPV vaccine is the most frequently offered (77% of countries) and the majority vaccination programmes include both girls and boys. As regards breast cancer screening, all thirty-two countries have an implemented screening programme. All countries perform mammography as the screening test, 62.5% of them begin in women aged 50 to 54, with a 2-yearly interval in the majority. In five countries, screening programmes are performed biennially, starting between 45 and 49 years old. Seven countries start in women aged 41 to 44.

CONCLUSIONS

There are discrepancies around gynaecological cancer screenings provision among EBCOG member countries. It is important to establish European recommendations about screening for gynaecological cancers, in order to standardize the access to equitable better health care in gynaecological cancers within Europe.

EBCOG position statement on Inequalities in screening for cervical and breast cancer

Gynaecological cancers, namely breast and cervical cancer represent a high burden in women's health. It is well established that cervical and breast cancer screening programmes are effective in reducing morbidity and mortality. It is of the most importance to define strategies to provide a universal access to screening. In European countries, significant progress has been made over the past years concerning screening strategies, namely the choice of screening test, its frequency as well as the age to start and stop the screening. Introduction of Human Papillomavirus vaccination programmes is also making a measurable impact to reduce cervical cancer prevalence and mortality. Our survey has shown a variation among European countries in delivery of cervical and breast cancer screening programmes. These variations can be due to organizational, economic or cultural reasons. The European Board and College of Obstetrics and Gynaecology calls for an implementation of a unified policy of prevention, screening and early detection of cervical and breast cancer across Europe to optimize clinical outcomes and reduce variations.

The cost-effectiveness profile of sex-neutral HPV immunisation in European tender-based settings: a model-based assessment

BACKGROUND

In many European countries, human papillomavirus (HPV) vaccine uptake among girls has remained below target levels, supporting the scope for vaccination of boys. We aimed to investigate if sex-neutral HPV vaccination can be considered cost-effective compared with girls-only vaccination at uptake levels equal to those among girls and under tender-based vaccination costs achieved throughout Europe.

METHODS

We investigated the cost-effectiveness of sex-neutral HPV vaccination in European tender-based settings. We applied a Bayesian synthesis framework for health economic evaluation to 11 countries (Austria, Belgium, Croatia, Estonia, Italy, Latvia, the Netherlands, Poland, Slovenia, Spain, and Sweden), accommodating country-specific information on key epidemiological and economic parameters, and on current HPV vaccination programmes. We used projections from three independently developed HPV transmission models to tailor region-specific herd effects. The main outcome measures in the comparison of sex-neutral with girls-only vaccination were cancer cases prevented and incremental cost-effectiveness ratios (ICERs), defined as the cost in international dollars (I$) per life-year gained.

FINDINGS

The total number of cancer cases to be prevented by vaccinating girls at currently realised vaccine uptake varied from 318 (95% CI 197-405) per cohort of 200 000 preadolescents (100 000 girls plus 100 000 boys) in Croatia (under 20% uptake of the 9-valent vaccine) to 1904 (1741-2101) in Estonia (under 70% uptake of the 9-valent vaccine). Vaccinating boys at equal coverage increased these respective numbers by 168 (95% CI 121-213) in Croatia and 467 (391-587) in Estonia. Sex-neutral vaccination was likely to be cost-effective, with ICERs of sex-neutral compared with girls-only vaccination varying from I$4300 per life-year gained in Latvia (95% credibility interval 3450-5160; 40% uptake) to I$25 720 per life-year gained in Spain (21 380-30 330; 80% uptake). At uniform 80% uptake, a favourable cost-effectiveness profile was retained for most of the countries investigated (Austria, Belgium, Italy, Latvia, the Netherlands, Slovenia, Spain, and Sweden).

INTERPRETATION

Sex-neutral HPV vaccination is economically attractive in European tender-based settings. However, tendering mechanisms need to ensure that vaccination of boys will remain cost-effective at high vaccine uptake rates.
