How Does Transitioning to Primary Human Papillomavirus Screening Impact Colposcopy Services? Lessons From an Australian National Program.

Objective: In 2017, Australian's National Cervical Screening Program changed from 2-yearly cytology to 5-yearly primary human papillomavirus (HPV) testing. The Stakeholder Opinions of Renewal Implementation and Experiences Study (STORIES) aimed to capture stakeholder perspectives during implementation of the renewed National Cervical Screening Program.

Materials And Methods: Qualitative semistructured interviews were conducted with key National Cervical Screening Program stakeholders 11-20 months following the change, either face-to-face, online, or via phone.

Correlates of intention-to-attend and confirmed cervical screening attendance during the COVID-19 pandemic in Australia: Findings from Compass-PLUS, a prospective cohort study.

Objective: The coronavirus pandemic impacted health-seeking behaviour and access to primary care in Australia. We investigated factors associated with intention-to-attend and attendance of cervical screening during the pandemic, mainly in Victoria, Australia.

Methods: We used questionnaire and attendance data (Aug 2020-Nov 2022) from Compass-PLUS, a sub-study of the Compass randomized-controlled trial of Human Papillomavirus-based vs cytology-based screening.

A modelled analysis of the impact of COVID-19-related disruptions to HPV vaccination.

COVID-19 disrupted school attendance in many countries, delaying routine adolescent vaccination against human papillomavirus (HPV) in some settings. We used , a dynamic model simulating HPV transmission, natural history, vaccination, cervical screening, and diagnosis of HPV-related cancers, to estimate the impact on HPV-related cancers from disruptions to HPV vaccination in a high-income setting. A baseline scenario of no disruption to HPV vaccination was modelled, which assumed uptake of the nonavalent vaccine at the age of 12 by 82.

Participation in the national cervical screening programme among women from New South Wales, Australia, by place of birth and time since immigration: A data linkage analysis using the 45 and up study.

Objective: Equitable elimination of cervical cancer in Australia within the next decade will require high National Cervical Screening Program (NCSP) participation by all subgroups of women. The aim of this study was to examine the participation of immigrants compared to Australian-born women.

Methods: Participation in the NCSP (≥1cytology test) over a 3-year (2010-2012) and 5-year (2008-2012) period, by place of birth and time since immigration was examined using individually linked data of 67,350 New South Wales (NSW) women aged ≥45 enrolled in the 45 and Up Study.

Implementation of Australia's primary human papillomavirus (HPV) cervical screening program: The STakeholders Opinions of Renewal Implementation and Experiences Study.

In this study, we aimed to document stakeholders' experiences of implementing Australia's renewed National Cervical Screening Program. In December 2017, the program changed from 2nd yearly cytology for 20-69 year olds to 5 yearly human papillomavirus (HPV) screening for women 25-74 years. We undertook semi-structured interviews with key stakeholders including government, program administrators, register staff, clinicians and health care workers, non-government organisations, professional bodies, and pathology laboratories from across Australia between Nov 2018 - Aug 2019.

The Indigenous Australian Human Papillomavirus (HPV) Cohort Study 2, Continuation for 5 to 10 Years: Protocol for a Longitudinal Study.

Background: Human papillomavirus (HPV) infection, a common sexually transmitted disease, is associated with cancers of the cervix, vulva, vagina, penis, anus, and head and neck. Oropharyngeal squamous cell carcinoma (OPSCC; throat cancer) is a type of cancer involving the head and neck area that is rapidly increasing across the globe. There are higher rates of OPSCC among Indigenous populations relative to non-Indigenous Australian populations, although the HPV-attributable fraction remains unknown.

An education resource for human papillomavirus oropharyngeal cancer patients: think-aloud interviews.

Purpose: The human papillomavirus (HPV) is well recognised as a factor in developing oropharyngeal cancer (OPC). A booklet for HPV-OPC patients aimed to deliver evidence-based messages in everyday language, in a way to minimise negative psychological impacts on patients. Our study explored the suitability of the booklet for use.

Exploring monitoring strategies for population surveillance of HPV vaccine impact using primary HPV screening.

Australia's cervical screening program transitioned from cytology to HPV-testing with genotyping for HPV16/18 in Dec'2017. We investigated whether program data could be used to monitor HPV vaccination program impact (commenced in 2007) on HPV16/18 prevalence and compared estimates with pre-vaccination benchmark prevalence. Pre-vaccination samples (2005-2008) (n = 1933; WHINURS), from 25 to 64-year-old women had been previously analysed with Linear Array (LA).

-Key Stakeholder Perspectives on the Initial Implementation of Self-Collection in Australia's Cervical Screening Program: A Qualitative Study.

Background: In December 2017, the Australian National Cervical Screening Program transitioned from 2-yearly cytology-based to 5-yearly human papillomavirus (HPV)-based cervical screening, including a vaginal self-collection option. Until July 2022, this option was restricted to under- or never-screened people aged 30 years and older who refused a speculum exam. We investigated the perspectives and experiences of stakeholders involved in, or affected by, the initial implementation of the restricted self-collection pathway.

A model-based analysis of the health impacts of COVID-19 disruptions to primary cervical screening by time since last screen for current and future disruptions.

We evaluated how temporary disruptions to primary cervical cancer (CC) screening services may differentially impact women due to heterogeneity in their screening history and test modality. We used three CC models to project the short- and long-term health impacts assuming an underlying primary screening frequency (i.e.

Health impacts of COVID-19 disruptions to primary cervical screening by time since last screen: A model-based analysis for current and future disruptions.

Background: We evaluated how temporary disruptions to primary cervical cancer (CC) screening services may differentially impact women due to heterogeneity in their screening history and test modality.

National experience in the first two years of primary human papillomavirus (HPV) cervical screening in an HPV vaccinated population in Australia: observational study.

Objective: To review the first two years of the primary human papillomavirus (HPV) cervical screening programme in an HPV vaccinated population.

Design: Observational study.

Setting: Australia.

Cancer Incidence in Migrants in Australia: Patterns of Three Infection-Related Cancers.

Background: Australia provides an ideal population-base for cancer migration studies because of its multicultural society and high-quality cancer registrations. Among migrant groups there is considerable variability in the incidence of infection-related cancers; thus, the patterns of three such cancers were examined among migrant groups relative to Australian-born residents.

Methods: Using national incidence data for cancers of the stomach, liver, and cervix diagnosed during 2005 to 2014, incidence rates were compared for selected migrant groups with the Australian-born population using incidence rate ratios (IRR), from a negative binomial regression model.

Oral HPV Infection among Indigenous Australians; Incidence, Persistence, and Clearance at 12-Month Follow-up.

Background: Persistent oral human papillomavirus (HPV) infection is a risk factor for oropharyngeal squamous cell carcinoma (OPSCC). Indigenous Australians have a higher rate of OPSCC than non-Indigenous Australians. Risk factors for oral HPV persistence among Indigenous Australians are poorly understood.

Impact of disruptions and recovery for established cervical screening programs across a range of high-income country program designs, using COVID-19 as an example: A modelled analysis.

COVID-19 has disrupted cervical screening in several countries, due to a range of policy-, health-service and participant-related factors. Using three well-established models of cervical cancer natural history adapted to simulate screening across four countries, we compared the impact of a range of standardised screening disruption scenarios in four countries that vary in their cervical cancer prevention programs. All scenarios assumed a 6- or 12-month disruption followed by a rapid catch-up of missed screens.

Cervical screening during the COVID-19 pandemic: optimising recovery strategies.

Disruptions to cancer screening services have been experienced in most settings as a consequence of the COVID-19 pandemic. Ideally, programmes would resolve backlogs by temporarily expanding capacity; however, in practice, this is often not possible. We aim to inform the deliberations of decision makers in high-income settings regarding their cervical cancer screening policy response.

Effective HPV vaccination coverage in Australia by number of doses and two-dose spacing: What if one or two doses are sufficient?

Background: Initially, three-dose schedules were recommended for vaccines against human papillomavirus (HPV); subsequently recommendations have been updated to a schedule of two doses delivered at least six (minimum five) months apart for those aged <15 years at dose 1. We aimed to re-estimate effective HPV vaccination coverage in Australia, considering reduced-dose schedules and possible one-dose effectiveness. We also aimed to identify which of the three school visits was most commonly missed amongst two-dose only recipients, to inform optimal timing of visits.

Impact of COVID-19-related care disruptions on cervical cancer screening in the United States.

Objectives: To quantify the secondary impacts of the COVID-19 pandemic disruptions to cervical cancer screening in the United States, stratified by step in the screening process and primary test modality, on cervical cancer burden.

Methods: We conducted a comparative model-based analysis using three independent NCI Cancer Intervention and Surveillance Modeling Network cervical models to quantify the impact of eight alternative COVID-19-related screening disruption scenarios compared to a scenario of no disruptions. Scenarios varied by the duration of the disruption (6 or 24 months), steps in the screening process being disrupted (primary screening, surveillance, colposcopy, excisional treatment), and primary screening modality (cytology alone or cytology plus human papillomavirus "cotesting").

Human papillomavirus vaccination for adults aged 30 to 45 years in the United States: A cost-effectiveness analysis.

Background: A nonavalent human papillomavirus (HPV) vaccine has been licensed for use in women and men up to age 45 years in the United States. The cost-effectiveness of HPV vaccination for women and men aged 30 to 45 years in the context of cervical cancer screening practice was evaluated to inform national guidelines.

Methods And Findings: We utilized 2 independent HPV microsimulation models to evaluate the cost-effectiveness of extending the upper age limit of HPV vaccination in women (from age 26 years) and men (from age 21 years) up to age 30, 35, 40, or 45 years.
