The USPSTF confirms its 2018 recommendation for screening postmenopausal women, but evidence still is insufficient to make a recommendation for men.

Objective
This study explored and compared stakeholder perspectives on enhancements to cervical cancer screening for vulnerable women across seven European countries.

Design
In a series of Collaborative User Boards, stakeholders were invited to collaborate on identifying facilitators to improve cervical cancer screening.

Setting
This study was part of the CBIG-SCREEN project which is funded by the European Union and targets disparities in cervical cancer screening for vulnerable women (www.cbig-screen.eu). Data collection took place in Bulgaria, Denmark, Estonia, France, Italy, Portugal and Romania.

Participants
Represented stakeholders at various levels, including user representatives (vulnerable women), healthcare professionals, social workers, programme managers and decision makers.

Methods
14 meetings lasting 2 hours each were held in these seven countries between October 2021 and June 2022. The meetings were audio or video recorded, transcribed and translated into English for qualitative framework analysis.

Results
We engaged 120 participants in the Collaborative User Boards. Proposed solutions targeted both provider and system levels. In all countries, fostering trusting relationships between vulnerable women and social or healthcare professionals, coupled with community outreach for awareness and access to testing was a consistent recommendation. Participants in Estonia, Denmark, France, Italy, Portugal and Romania advocated for tailoring healthcare services to meet the unique needs of vulnerable populations through a holistic approach. In Bulgaria and Romania, participants advocated for the need to secure free access, from screening to follow-up, and emphasised the need for organised screening with target population screening registries.

Conclusion
The study offers insights into stakeholders’ recommendations for enhancing cervical cancer screening services for vulnerable women across seven European countries. Despite variations in the implementation level of population-based screening programmes, the imperative to optimise outreach and proximity work to improve cervical cancer screening resonated across all countries.

Background
Worldwide, lung cancer (LC) is the second most frequent cancer and the leading cause of cancer related mortality. Low-dose CT (LDCT) screening reduced LC mortality by 20–24% in randomised trials of high-risk populations. A significant proportion of those screened have nodules detected that are found to be benign. Consequently, many individuals receive extra imaging and/or unnecessary procedures, which can have a negative physical and psychological impact, as well as placing a financial burden on health systems. Therefore, there is a need to identify individuals who need no interval CT between screening rounds.

Methods and analysis
The aim of this study is to identify risk factors predictive of LC, which are known at the time of the scan, in patients with LDCT screen-detected lung nodules. The MEDLINE and EMBASE databases will be searched and articles that are on cohorts or mention cohorts of screenees with nodules will be identified. A data extraction framework will ensure consistent extraction across studies. Individual participant data (IPD) will be collected to perform a one-stage IPD meta-analysis using hierarchical univariate models. Clustering will be accounted for by having separate intercept terms for each cohort. Where IPD is not available, the effects of risk factors will be extracted from publications, if possible. Effects from IPD cohorts and aggregate data will be reported and compared. The PROBAST (Prediction model Risk Of Bias ASsessment Tool) will be used for assessment of quality of the studies.

Ethics and dissemination
Ethical approval was not required as this study is a secondary analysis. The results will be disseminated through publication in peer-reviewed journals and presentations at relevant conferences.

Objective
Screening for cervical cancer has been a globally advocated preventive strategy to reduce cervical cancer morbidity and mortality. This study aimed to describe the prevalence and barriers of cervical cancer screening, and to determine factors associated with cervical cancer screening among women of reproductive age in Moshi municipality, northern Tanzania.

Design
We conducted a cross-sectional study between August and September 2020.

Setting
Moshi municipality, Kilimanjaro, Tanzania.

Participants
Women of ages 15–49 years who live in Moshi municipality.

Results
A total of 300 women participated in the study and 22.7% had ever been screened for cervical cancer. Women below the age of 30 years had 87% lower odds of screening for cervical cancer compared with those aged 30 years and above (OR 0.13; 95% CI 0.04, 0.43). Women who had never heard about cervical cancer had 94% (OR 0.06; 95% CI 0.01, 0.51) lower odds of screening compared with those who ever heard about the disease. In comparison to married women, those who identified as single had 71% lower odds of screening for cervical cancer (OR 0.29; 95% CI 0.10, 0.73). Women without formal education or with only primary-level education had 72% lower odds of screening for cervical cancer compared with those with college or university education (OR 0.28; 95% CI 0.08, 0.98). A lack of awareness on where to screen and a lack of comprehensive knowledge about cervical cancer were reported as screening barriers among those who had never been tested.

Conclusion
Only one in five women have ever been screened for cervical cancer, despite the majority having heard about the disease. Overall knowledge of cervical cancer was low, with many women unaware of its causes, risk factors and preventive measures. Key barriers to screening included a lack of awareness and insufficient medical advice. Factors significantly associated with lower odds of screening were being under age of 30 years, not having heard about cervical cancer, having no formal or only primary education and being single. There is an urgent need for community-based interventions to increase awareness and education about cervical cancer and to improve access to screening services, especially for younger, less educated and single women.

Continuous monitoring of PCa screening programmes using the KPIs will serve as a powerful tool for optimizing service delivery, programme improvement, comparison per screening site, and ultimately contributing to a better benefit to harm ratio. The KPIs will be implemented in five pilot sites identified to be included in the PRAISE-U project aiming to identify an evidence-based scalable model for risk adapted PCa screening for Europe.

Background
Cervical cancer (CC) is preventable through regular screening and vaccination against human papillomavirus (HPV). However, CC remains a significant public health issue in low-income and middle-income countries (LMICs) like Vietnam, where financial constraints hinder the widespread implementation of HPV vaccination and screening programmes. Currently, Vietnam lacks both a national CC screening intervention and an HPV vaccination programme for women and girls. To date, cost-effectiveness studies evaluating CC screening methods in Vietnam remain limited.

Objectives
To evaluate the cost-effectiveness of two CC screening strategies for Vietnamese women aged 25–55 years: (1) cotesting combining cytology and HPV testing conducted three times at 5 year intervals (intervention) and (2) cytology-based screening conducted five times at 2 year intervals (comparator). The objective is to provide evidence to inform policy and clinical practice in Vietnam.

Design
Cost-effectiveness analysis using a Markov model with 1 year cycles to simulate the natural progression of CC.

Setting
The Vietnamese healthcare system, modelled from the provider’s perspective, with parameters adapted to the local context through expert consultations.

Participants
A simulated cohort of Vietnamese women aged 25–55 years.

Interventions
The intervention involved cotesting (cytology and HPV testing) three times at 5 year intervals. The comparator was cytology-based screening conducted five times at 2 year intervals.

Primary and secondary outcome measures
The primary outcome measure was quality-adjusted life years (QALYs). Costs and cost-effectiveness ratios were assessed using Vietnam’s gross domestic product (GDP) per capita as the cost-effectiveness threshold (1–3 times GDP per capita). Sensitivity analyses (one-way deterministic and probabilistic) were conducted to account for uncertainties.

Results
The cotesting strategy was less effective and more costly than cytology-based screening across all age groups. Cotesting resulted in higher costs and fewer QALYs than the comparator. Probabilistic sensitivity analyses confirmed that cotesting was not cost-effective under current conditions in Vietnam.

Conclusions
Cytology-based screening conducted five times at 2 year intervals is a more cost-effective option for CC screening in Vietnamese women aged 25–55 years. The cotesting strategy cannot be recommended due to its higher cost and lower effectiveness.

Today’s genomic technology introduces a multitude of assays that could be deployed in health care: diagnostic testing of patients with suspected monogenic conditions, polygenic risk prediction for common diseases, pharmacogenomic analysis for drug-gene interactions, analysis of tumors for targetable somatic sequence variations, and noninvasive screening for prenatal chromosomal disorders or occult cancer. Alongside these approaches we must also grapple with screening of the ostensibly healthy population for monogenic diseases of newborns, children, and adults with either targeted or genome-scale sequencing.

This multisite, single-group, prospective, observational study examines the feasibility and potential impact of genomic newborn screening using dried blood spots in a racially and ethnically diverse population from New York State.
