Curr Oncol 2023; 30:7692-7705. [PMID: 37623038 PMCID: PMC10453046 DOI: 10.3390/curroncol30080557] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 08/08/2023] [Accepted: 08/16/2023] [Indexed: 08/26/2023] Open
Abstract
This study examined invasive cervical cancer (ICC) incidence trends in British Columbia (BC) by age and stage-at-diagnosis relative to World Health Organization ICC elimination targets (4 per 100,000 persons). Incident ICC cases (1971-2017) were obtained from the BC Cancer Registry. Annual age-standardized incidence rates (ASIRs) per 100,000 persons were generated using the direct method. ASIRs were examined among all ages 15+ years and eight age groups using Joinpoint Regression with the Canadian 2011 standard population. Standardized rate ratios (SRRs) compared stage II-IV (late) versus stage I (early) ASIRs by age (2010-2017). ICC ASIRs did not reach the elimination target. ASIRs declined from 18.88 to 7.08 per 100,000 persons (1971-2017). Stronger declines were observed among ages 45+ years, with the largest decline among ages 70-79 years (AAPC = -3.2%, 95% CI = -3.9% to -2.6%). Among ages 25-69 years, varying levels of attenuation in declining trends and stabilization were observed since the 1980s. SRRs indicated higher rates of late-stage ICC among ages 55+ years (SRR-55-69 years = 1.34, 95% CI = 1.08-1.71). Overall, ICC incidence declined in BC since 1971 but did not reach the elimination target. The pace of decline varied across age groups and increased with age. Continued efforts are needed to progress cervical cancer elimination among all age groups.

Abstract
INTRODUCTION To assess outcome of a one-time human papillomavirus (HPV)-screening in 2017 of Danish women aged 70+. MATERIAL AND METHODS Women born 1947 or before were personally invited to have a cell-sample collected by their general practitioner. Screening- and follow-up samples were analyzed in hospital laboratories in the five Danish regions and registered centrally. Follow-up procedures varied slightly across regions. Cervical intraepithelial neoplasia 2 (CIN2) was recommended treatment threshold. Data were retrieved from the Danish Quality Database for Cervical Cancer Screening. We calculated CIN2+ and CIN3+ detection rates per 1000 screened women, and number of biopsies and conizations per detected CIN2+ case. We tabulated annual number of incident cervical cancer cases in Denmark for the years 2009-2020. RESULTS In total, 359 763 women were invited of whom 108 585 (30% of invited) were screened; 4479 (4.1% of screened, and 4.3% of screened 70-74 years) tested HPV-positive; of whom 2419 (54% of HPV-positive) were recommended follow-up with colposcopy, biopsy and cervical sampling, and 2060 with cell-sample follow-up. In total, 2888 women had histology; of whom 1237 cone specimen and 1651 biopsy only. Out of 1000 screened women 11 (95% confidence interval [CI]: 11-12) had conization. In total, 579 women had CIN2+; 209 CIN2, 314 CIN3, and 56 cancer. Out of 1000 screened women five (95% CI: 5-6) had CIN2+. Detection rate of CIN2+ was highest in regions where conization was used as part of first-line follow-up. In 2009-2016, number of incident cervical cancers in women aged 70+ in Denmark fluctuated around 64; in 2017 it reached 83 cases; and by 2021 the number had decreased to 50. CONCLUSIONS The prevalence of high-risk HPV of 4.3% in women aged 70-74 is in agreement with data from Australia, and the detection of five CIN+2 cases per 1000 screened women is in agreement with data for 65-69 year old women in Norway. Data are thus starting to accumulate on primary HPV-screening of elderly women. The screening resulted in a prevalence peak in incident cervical cancers, and it will therefore take some years before the cancer preventive effect of the screening can be evaluated.

HPV Testing Behaviors and Willingness to Use HPV Self-sampling at Home Among African American (AA) and Sub-Saharan African Immigrant (SAI) Women. J Racial Ethn Health Disparities 2022; 9:2485-2494. [PMID: 34780021 PMCID: PMC10060062 DOI: 10.1007/s40615-021-01184-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2021] [Revised: 10/27/2021] [Accepted: 10/30/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND HPV self-sampling is an emerging HPV testing method that offers reliable identification of cervical precancer and cancer. To determine the feasibility of HPV self-sampling in the USA, information is needed regarding women's use of HPV test and willingness to use self-sampling, especially among disparate groups such as African American (AA) and sub-Saharan African immigrant (SAI) women. The purpose of this study was to examine factors associated with having had at least one HPV test and willingness to use HPV self-sampling among AA and SAI women. METHODS AA and SAI women (n = 91) recruited from community settings completed a survey in a cross-sectional study. Data included sociodemographics, HPV and HPV testing knowledge, and willingness to use a HPV self-sampling test at home. Logistic regressions were performed to evaluate associations with having had a HPV test and willingness to use self-sampling. RESULTS Respondents mean age was 38.2 years (SD = 12.6) and 65% were SAIs. The majority (84%) reported having had at least one Pap test and (36%) had at least one HPV test. Sixty-seven percent were willing to self-sample at home. Age, education, and HPV testing knowledge were associated with having had a HPV test. Being uninsured and likelihood to accept a Pap test if recommended were associated with willingness to use self-sampling at home for an HPV test. CONCLUSIONS Health care providers have an important role in recommending cervical cancer screening according to current guidelines. HPV self-sampling may be a promising strategy to reach older, less educated, uninsured, and underinsured Black women.

Abstract
INTRODUCTION Cervical cancer screening ceases between the ages of 60 and 65 in most countries. Yet, a relatively high proportion of cervical cancers are diagnosed in women above the screening age. This study will evaluate if screening of women aged 65-69 years may result in increased detection of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) compared with women not invited to screening. Invited women may choose between general practitioner (GP)-based screening or cervico-vaginal self-sampling. Furthermore, the study will assess if self-sampling is superior to GP-based screening in reaching long-term unscreened women. METHODS AND ANALYSIS This population-based non-randomised intervention study will include 10 000 women aged 65-69 years, with no record of a cervical cytology sample or screening invitation in the 5 years before inclusion. Women who have opted-out of the screening programme or have a record of hysterectomy or cervical amputation are excluded. Women residing in the Central Denmark Region (CDR) are allocated to the intervention group, while women residing in the remaining four Danish regions are allocated to the reference group. The intervention group is invited for human papillomavirus-based screening by attending routine screening at the GP or by requesting a self-sampling kit. The reference group receives standard care which is the opportunity to have a cervical cytology sample obtained at the GP or by a gynaecologist. The study started in April 2019 and will run over the next 4.5 years. The primary outcome will be the proportion of CIN2+ detected in the intervention and reference groups. In the intervention group, the proportion of long-term unscreened women attending GP-based screening or self-sampling will be compared. ETHICS AND DISSEMINATION The study has been submitted to the Ethical Committee in the CDR which deemed that the study was not notifiable to the Committee and informed consent is therefore not required. The study is approved by the Danish Data Protection Regulation and the Danish Patient Safety Authority. Results will be disseminated in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT04114968.

Abstract
BACKGROUND Cervical screening attendance among 50-64 year-olds is suboptimal. Understanding attitudes to screening and reasons for non-attendance in older women will help to identify the content of interventions for this age group. This study aimed to explore barriers to cervical screening among women aged 50-64 years from hard-to-reach groups whose perspectives are often absent from research on cervical screening but are critical to developing appropriate interventions to increase engagement with the screening offer. METHODS Qualitative methodology was used. Six focus groups were carried out with women aged 50-64 years from lower socio-economic and ethnic minority backgrounds (n = 38). Focus group discussions were recorded, transcribed verbatim and translated where necessary. Data were analysed using the Framework Approach, a type of thematic analysis. RESULTS All women had heard of cervical screening, but many felt they had poor knowledge. Women's reasons for non-attendance were wide-ranging and included discomfort and embarrassment, negative perceptions of health professionals, worry and trust in the results, concern about the procedure, idiosyncratic beliefs, and extreme negative experiences. Some women reported not receiving letters or prompts to be screened. CONCLUSIONS Information designed specifically for older women should ensure they understand the purpose of screening and its relevance to them. Emphasising changes to the programme that have made the experience less uncomfortable, and improved sample taker awareness of how women feel, may help to allay concerns related to previous negative experiences.

Abstract
OBJECTIVES One reason that women over age 50 report avoiding cervical screening is increased discomfort postmenopause. This study aimed to explore the acceptability of human papillomavirus testing on clinician-collected vaginal samples without a speculum ('non-speculum') for cervical screening among older women. METHODS Thirty-eight women in England aged 50-64 with a range of cervical screening experience ('up-to-date' n = 17, 'overdue screening' n = 18, 'never screened' n = 3) were identified via a recruitment agency. Women participated in focus groups or interviews about the potential for using clinician-collected samples without a speculum. Discussions were analysed using Framework Analysis. RESULTS The two main themes identified were women's perceptions of the speculum and attitudes towards non-speculum screening. Many women reported negative experiences with the speculum, including increased pain after the menopause. Women generally had positive attitudes towards non-speculum clinician sampling and felt it would be a less intrusive option, but expressed concern that it could be less accurate than screening with a speculum. Women who were 'up-to-date' preferred conventional screening, while overdue and never screened women welcomed the option to be screened without a speculum. CONCLUSIONS Human papillomavirus testing on non-speculum clinician-collected vaginal samples could be an acceptable alternative cervical screening method for older women. Offering this approach could increase screening uptake in older women who find conventional cervical screening to be less acceptable with ageing or the menopause.

Abstract
BACKGROUND Although preventive measures have greatly decreased the national burden of cervical cancer, racial/ethnic and geographic disparities remain, including the disproportionate incidence and mortality among African American women in the Mississippi Delta. Along with structural barriers, health perceptions and cultural beliefs influence participation in cervical screening. This study examined perceived susceptibility to cervical cancer among African American women in the Delta across three groups: 1) women attending screening appointments (screened), 2) women attending colposcopy clinic following an abnormal Papanicolaou test (colposcopy), and 3) women with no screening in 3 years or longer (unscreened/underscreened). METHODS Data were collected during a study assessing the feasibility/acceptability of self-collected sampling for human papillomavirus (HPV) testing as a cervical screening modality. A questionnaire assessed demographics, health care access, and cervical cancer knowledge and beliefs (including perceived susceptibility). Participants were asked, "Do you think you are at risk for cervical cancer?", and responses included yes, no, and I don't know. Multinomial logistic regression models compared variables associated with answers among each group. RESULTS Of 524 participants, one-half did not know if they were at risk of cervical cancer (50%) or HPV exposure (53%). Between the unscreened/underscreened (n = 160), screened (n = 198), and colposcopy (n = 166) groups, age (p < .001), education (p = .02), and perceived risk of HPV exposure (p < .01) differed. Older age and younger age at first intercourse (unscreened/underscreened), family history and screening recommendations (screened), and family history and perceived risk of HPV exposure (colposcopy) were associated with perceived susceptibility to cervical cancer. CONCLUSIONS Differences in the perceived susceptibility to cervical cancer exist between African American women in the Delta. Understanding these variations can help in developing strategies to promote screening among this population with a high burden of disease.

Abstract
INTRODUCTION Leading professional organizations recommend cervical cancer screening for average-risk women aged 21-65 years. For average-risk women aged >65 years, routine screening may be discontinued if "adequate" screening with negative results is documented. Screening is recommended after age 65 years for women who do not meet adequate prior screening criteria or are at special risk. METHODS Authors examined the most recent cervical cancer incidence data from two federal cancer surveillance programs for all women by age and race, corrected for hysterectomy status. The 2013 and 2015 National Health Interview Surveys were analyzed in 2016 to examine the proportion of women aged 41-70 years without a hysterectomy who reported that they never had a Pap test or that their most recent Pap test was >5 years ago (not recently screened). RESULTS The incidence rate for cervical cancer among older women, corrected for hysterectomy status, did not decline until age ≥85 years. The proportion not recently screened increased with age, from 12.1% for women aged 41-45 years to 18.4% for women aged 61-65 years. CONCLUSIONS Even among women within the recommended age range for routine screening, many are not up to date, and a substantial number of women approach the "stopping" age for cervical cancer screening without an adequate prior screening history. Efforts are needed to reach women who have not been adequately screened, including women aged >65 years, to prevent invasive cervical cancer cases and deaths among older women.

Abstract
Cervical cancer is the fourth most common cancer in women worldwide (WHO, 2016). In many developed countries the incidence of cervical cancer has been significantly reduced by the introduction of organised screening programmes however, in the UK, a fall in screening coverage is becoming a cause for concern. Much research attention has been afforded to younger women but age stratified mortality and incidence data suggest that older women's screening attendance is also worthy of study. This paper provides a review of current evidence concerning the psycho-social influences that older women experience when deciding whether to attend cervical screening. Few studies have focussed on older women and there are significant methodological issues with those that have included them in their samples. Findings from these studies indicate several barriers which may deter older women from screening, such as embarrassment and logistical issues. Drivers to screening include reassurance and a sense of obligation. Physical, social and emotional changes that occur as women age may also have an impact on attendance. This review concludes that there is a clear need for better understanding of the perceptions of older women specifically with regard to cervical cancer and screening. Future research should inform the design of targeted interventions and provision of information to enable informed decision-making regarding cervical screening among older women.

Abstract
AIM In many countries, the age-specific pattern of cervical cancer incidence is currently bipolar with peaks at for instance 45 and 65 years of age. Consequently, a large proportion of cervical cancer cases are presently diagnosed in women above the screening age. The purpose of the study was to determine whether this bipolar pattern in age-specific incidence of cervical cancer reflects underlying biology or can be explained by the fact that the data come from birth cohorts with different screening histories. METHODS Combination of historical data on cervical screening and population-based cancer incidence data from Denmark 1943-2013, Finland and Norway 1953-2013, and Sweden 1958-2013. RESULTS Since the implementation of screening, the incidence of cervical cancer has decreased for each successive birth cohort. All birth cohorts showed a unipolar age-specific pattern. In unscreened women in Denmark and Sweden, the incidence peaked around the age of 50; the peak was less marked in Finland; while peak age for unscreened women could not be determined for Norway due to widespread opportunistic screening. The current old-age peak in the incidence of cervical cancer represents residuals from unscreened or underscreened birth cohorts. CONCLUSION The current bipolar pattern in age-specific incidence of cervical cancer can largely be explained by the different screening histories of successive birth cohorts. While it is reasonable to offer screening to elderly women today, birth cohort trends in disease burden should be carefully monitored to justify permanent changes in upper screening age.

Abstract
Invasive cervical cancer disproportionately affects women without sufficient access to care, with higher rates among minority groups in higher-income countries and women in low-resource regions of the world. Many elements contribute to racial/ethnic disparities in the cervical cancer continuum - from screening and diagnosis to treatment and outcome. Sociodemographic factors, access to healthcare, income and education level, and disease stage at diagnosis are closely linked to such inequities. Despite the identification of such elements, racial/ethnic disparities persist, and are widening in several minority subgroups, particularly in older women, who are ineligible for human papillomavirus (HPV) vaccination and are underscreened. Recent studies suggest that racial/ethnic differences in HPV infection exist and may also have a role in observed differences in cervical cancer. In this review, we provide an overview of the current literature on racial disparities in cervical cancer screening, incidence, treatment and outcome to inform future strategies to reduce persistent inequities.

Evidence of disrupted high-risk human papillomavirus DNA in morphologically normal cervices of older women. Sci Rep 2016; 6:20847. [PMID: 26875676 PMCID: PMC4753489 DOI: 10.1038/srep20847] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2015] [Accepted: 01/12/2016] [Indexed: 12/31/2022] Open
Abstract
High-risk human papillomavirus (HR-HPV) causes nearly 100% of cervical carcinoma. However, it remains unclear whether HPV can establish a latent infection, one which may be responsible for the second peak in incidence of cervical carcinoma seen in older women. Therefore, using Ventana in situ hybridisation (ISH), quantitative PCR assays and biomarkers of productive and transforming viral infection, we set out to provide the first robust estimate of the prevalence and characteristics of HPV genomes in FFPE tissue from the cervices of 99 women undergoing hysterectomy for reasons unrelated to epithelial abnormality. Our ISH assay detected HR-HPV in 42% of our study population. The majority of ISH positive samples also tested HPV16 positive using sensitive PCR based assays and were more likely to have a history of preceding cytological abnormality. Analysis of subsets of this population revealed HR-HPV to be transcriptionally inactive as there was no evidence of a productive or transforming infection. Critically, the E2 gene was always disrupted in those HPV16 positive cases which were assessed. These findings point to a reservoir of transcriptionally silent, disrupted HPV16 DNA in morphologically normal cervices, re-expression of which could explain the increase in incidence of cervical cancer observed in later life.
