RESUMO

BACKGROUND: Trials are underway to test the clinical utility of multi-cancer early detection (MCED) blood tests for screening asymptomatic individuals. We sought to understand the acceptability of MCED blood test screening and potential barriers and facilitators to participation among the general public. METHODS: We conducted eleven semi-structured online focus groups with 50-77-year-olds (n = 53) in April-November 2022. Participants were purposefully sampled to include a mix of socio-economic and ethnic backgrounds as well as people who would not want 'a blood test for cancer'. Participants were shown information about MCED blood tests. Transcripts were analysed using reflexive thematic analysis. RESULTS: Participants showed enthusiasm for MCED screening. Perceived benefits included procedural familiarity and the potential to screen for many cancers. Enthusiasm was driven by beliefs that cancer is a real and increasing risk (both at population level and personally with age) and that early detection reduces treatment burden and cancer mortality. Some felt they would not want to know if they had cancer. The potential for MCED tests to raise anxiety was a concern, especially in a false-positive scenario. Participants wanted to avoid unpleasant and unnecessary procedures. The initial blood test was deemed "less invasive" than current screening tests, but potential follow-up procedures were a concern. Views on MCED screening were influenced by wider factors including dislike of uncertainty, desire for choice and control over one's health, and existing relationships with the NHS. CONCLUSION: The introduction of MCED screening is likely to be appealing due to the simplicity and familiarity of the primary test procedure. Test accuracy needs to be high to facilitate acceptability and should be communicated from the outset. Some people would rather not know if they have cancer, and MCEDs will not appeal to all.

RESUMO

Anaplastic thyroid carcinoma is arguably the most lethal human malignancy. It often co-occurs with differentiated thyroid cancers, yet the molecular origins of its aggressivity are unknown. We sequenced tumor DNA from 329 regions of thyroid cancer, including 213 from patients with primary anaplastic thyroid carcinomas. We also whole genome sequenced 9 patients using multi-region sequencing of both differentiated and anaplastic thyroid cancer components. Using these data, we demonstrate thatanaplastic thyroid carcinomas have a higher burden of mutations than other thyroid cancers, with distinct mutational signatures and molecular subtypes. Further, different cancer driver genes are mutated in anaplastic and differentiated thyroid carcinomas, even those arising in a single patient. Finally, we unambiguously demonstrate that anaplastic thyroid carcinomas share a genomic origin with co-occurring differentiated carcinomas and emerge from a common malignant field through acquisition of characteristic clonal driver mutations.

RESUMO

OBJECTIVES: Cervical screening uptake in England is falling. Infographics could strengthen intention to attend, increase positive attitudes and improve knowledge. Age targeting could improve these outcomes further. We tested the impact of generic and age-targeted infographics. DESIGN: A randomized controlled trial using an age-stratified, parallel-group design. METHODS: Women aged 25-64 (n = 2095) were recruited through an online panel and randomized to see one of the three infographics. We tested: (i) impact of a generic cervical screening infographic compared to a control infographic on an unrelated topic with all screening age women and (ii) impact of an age-targeted infographic compared to a generic cervical screening infographic with older women (50-64 years). Intentions, knowledge and attitudes were measured. RESULTS: Women aged 25-64 years who viewed the generic infographic had significantly higher intentions [F(1, 1513) = 6.14, p = .013, η p 2 = .004], more accurate beliefs about the timeline of cervical cancer development (OR: 5.18, 95% CI: 3.86-6.95), more accurate social norms (OR: 3.03, 95% CI: 2.38-3.87) and more positive beliefs about screening benefits (OR: 2.23, 95% CI: 1.52-3.28) than those viewing the control infographic. In the older age group, there was no significant difference in intention between those viewing the generic versus age-targeted versions [F(1, 607) = .03, p = .853, η p 2 < .001], but the age-targeted version was more engaging [F(1, 608) = 9.41, p = .002, η p 2 = .015]. CONCLUSIONS: A cervical screening infographic can result in more positive attitudes and better knowledge and may have a small impact on intentions. Although age targeting did not affect intention, it had a positive impact on engagement and may therefore be useful in encouraging women to read and process materials.

RESUMO

Background: CDK4/6 inhibitors (CDK4/6i) have been established as standard treatment against advanced Estrogen Receptor-positive breast cancers. These drugs are being tested against several cancers, including in combinations with other therapies. We identified the T172-phosphorylation of CDK4 as the step determining its activity, retinoblastoma protein (RB) inactivation, cell cycle commitment and sensitivity to CDK4/6i. Poorly differentiated (PDTC) and anaplastic (ATC) thyroid carcinomas, the latter considered one of the most lethal human malignancies, represent major clinical challenges. Several molecular evidence suggest that CDK4/6i could be considered for treating these advanced thyroid cancers. Methods: We analyzed by two-dimensional gel electrophoresis the CDK4 modification profile and the presence of T172-phosphorylated CDK4 in a collection of 98 fresh-frozen tissues and in 21 cell lines. A sub-cohort of samples was characterized by RNA sequencing and immunohistochemistry. Sensitivity to CDK4/6i (palbociclib and abemaciclib) was assessed by BrdU incorporation/viability assays. Treatment of cell lines with CDK4/6i and combination with BRAF/MEK inhibitors (dabrafenib/trametinib) was comprehensively evaluated by western blot, characterization of immunoprecipitated CDK4 and CDK2 complexes and clonogenic assays. Results: CDK4 phosphorylation was detected in all well-differentiated thyroid carcinomas (n=29), 19/20 PDTC, 16/23 ATC and 18/21 thyroid cancer cell lines, including 11 ATC-derived ones. Tumors and cell lines without phosphorylated CDK4 presented very high p16CDKN2A levels, which were associated with proliferative activity. Absence of CDK4 phosphorylation in cell lines was associated with CDK4/6i insensitivity. RB1 defects (the primary cause of intrinsic CDK4/6i resistance) were not found in 5/7 tumors without detectable phosphorylated CDK4. A previously developed 11-gene expression signature identified the likely unresponsive tumors, lacking CDK4 phosphorylation. In cell lines, palbociclib synergized with dabrafenib/trametinib by completely and permanently arresting proliferation. These combinations prevented resistance mechanisms induced by palbociclib, most notably Cyclin E1-CDK2 activation and a paradoxical stabilization of phosphorylated CDK4 complexes. Conclusion: Our study supports further clinical evaluation of CDK4/6i and their combination with anti-BRAF/MEK therapies as a novel effective treatment against advanced thyroid tumors. Moreover, the complementary use of our 11 genes predictor with p16/KI67 evaluation could represent a prompt tool for recognizing the intrinsically CDK4/6i insensitive patients, who are potentially better candidates to immediate chemotherapy.

RESUMO

INTRODUCTION: Multi-cancer early detection (MCED) blood tests look for cancer signals in cell-free deoxyribonucleic acid. These tests have the potential to detect cancers at an earlier (asymptomatic) stage, improving cancer outcomes. Any screening method needs careful consideration of the psychological harms prior to implementation. The aim of this research is to explore the psychological impact of having a cancer signal detected following an MCED blood test. METHODS AND ANALYSIS: The project is embedded in the NHS-Galleri trial (ISRCTN91431511; NCT05611632), a large clinical trial in eight Cancer Alliances in England. In the trial, over 140 000 members of the general population aged 50-77 have been randomised 1:1 to either the intervention (blood tested with MCED test) or control (blood stored) arm. The proposed project focuses on participants in the intervention arm, who have a cancer signal detected. All participants who have a cancer signal detected (expected to be around 700 assuming a 1% test positive rate) will be sent a questionnaire at three timepoints: soon after receiving their result, 6 months and approximately 12 months later. The primary outcome is anxiety, assessed using the short-form 6-item Spielberger State Trait Anxiety Inventory. We will also assess the psychological consequences of screening (using the Psychological Consequences of Screening Questionnaire), reassurance/concern about the test result, understanding of results and help/health-seeking behaviour. A subsample of 40 participants (20 with a cancer diagnosis and 20 for whom no cancer was found) will be invited to take part in a one-to-one semistructured interview. ETHICS AND DISSEMINATION: Ethical approval for this work has been granted by the Wales Research Ethics Committee as part of the NHS-Galleri trial (Ref 21/WA/0141). Consent to be sent questionnaires is collected as part of the main trial. A separate consent form will be required for interview. Results will be disseminated via peer-reviewed publication and conference presentations.

RESUMO

OBJECTIVES: To examine the psychosexual impact and disclosure experiences of women testing HPV-positive following cervical screening. DESIGN: In-depth semi-structured interviews. METHODS: Interviews were conducted with 21 women of screening age (i.e. those aged 24-65 years) in England who self-reported testing HPV-positive in the context of cervical screening in the last 12 months. Data were analysed using Framework Analysis. RESULTS: The sexually transmitted nature of HPV, and aspects relating to the transmission of HPV and where their HPV infection had come from, had an impact on women's current, past and future interpersonal and sexual relationships. Most women had disclosed their HPV infection to others, however the factors influencing their decision, and others' reactions to disclosure differed. The magnitude and extent of psychosexual impact was influenced by how women conceptualized HPV, their understanding of key aspects of the virus, concerns about transmitting HPV and having a persistent HPV infection. CONCLUSIONS: Increasing knowledge of key aspects of HPV, such as its high prevalence and spontaneous clearance, and the differences between HPV and other STIs, may increase women's understanding of their screening result and reduce any negative psychosexual consequences of testing HPV-positive. Referring to HPV as an infection that is passed on by skin-to-skin contact during sexual activity, rather than an STI, may help to lessen any psychosexual impact triggered by the STI label.

RESUMO

Over 20% of women aged 50-64 in Britain have not attended cervical screening within the recommended 5-year interval. The aim of the present study was to investigate the impact of five messages, informed using strategies from the Behaviour Change Wheel, on strength of intention to attend cervical screening in women aged 50-64 with weak positive intentions to be screened when next invited. Women were randomised (2:2:1), into one of two intervention groups or a control group. The control group saw basic information about cervical screening. Intervention group 1 saw a social norms message and an outcome expectancy message. Intervention group 2 saw a risk reduction message and a response efficacy message. There was further randomisation within the two intervention groups (1:1) to test the effectiveness of message framing and age-targeted information. Lastly, both intervention groups were randomised (1:1) to see a message acknowledging the possible discomfort associated with screening and offering support, or the support message only. Data were included from 475 women, collected using an online survey in March 2022. Adjusting for baseline intention, social norms (p = .84), outcome expectancy (p = .51), risk reduction (p = .19), response efficacy (p = .23) and discomfort acknowledgement messages (p = .71) had no effect on intention strength. However, there was a significant increase in intention after reading multiple messages. These results suggest that although no single message has a significant impact on intentions, when combined, they may act together to increase intention strength. Further research will understand the impact of these messages when combined in information materials.

RESUMO

OBJECTIVES: The introduction of primary Human Papillomavirus (HPV) testing in the National Health Service (NHS) Cervical Screening Programme in England means the screening interval for 25-49 years can be extended from 3 to 5 years. We explored women's responses to the proposed interval extension. METHODS: We conducted semi-structured phone/video interviews with 22 women aged 25-49 years. Participants were selected to vary in age, socioeconomics and screening history. We explored attitudes to the current 3-year interval, then acceptability of a 5-year interval. Interviews were transcribed verbatim and analysed using framework analysis. RESULTS: Attitudes to the current 3-year interval varied; some wanted more frequent screening, believing cancer develops quickly. Some participants worried about the proposed change; others trusted it was evidence based. Frequent questions concerned the rationale and safety of longer intervals, speed of cancer development, the possibility of HPV being missed or cell changes occurring between screens. Many participants felt reassured when the interval change was explained alongside the move to HPV primary screening, of which most had previously been unaware. CONCLUSIONS: Communication of the interval change should be done in the context of broader information about HPV primary screening, emphasising that people who test negative for HPV are at lower risk of cell changes so can safely be screened every 5 years. The long time needed for HPV to develop into cervical cancer provides reassurance about safety, but it is important to be transparent that no screening test is perfect.

RESUMO

BACKGROUND: Testing positive for human papillomavirus (HPV) at cervical cancer screening has been associated with heightened anxiety. To date, the cognitive determinants of heightened anxiety remain unclear, making it difficult to design effective interventions. PURPOSE: This study investigated latent illness representation profiles in women testing positive for HPV with no abnormal cells (normal cytology) and explored associations between these profiles and anxiety. METHODS: Women aged 24-66 (n = 646) who had tested HPV-positive with normal cytology at routine HPV primary screening in England completed a cross-sectional survey shortly after receiving their result. RESULTS: Latent profile analysis identified three distinct profiles of illness representations (termed "adaptive," "negative," and "negative somatic"), which differed significantly in their patterns of illness perceptions. Hierarchal linear regression revealed that these latent illness representation profiles accounted for 21.8% of the variance in anxiety, after adjusting for demographic and clinical characteristics. When compared with adaptive representations (Profile 1), women with negative representations (Profile 2) and negative somatic representations (Profile 3) had significantly higher anxiety, with clinically meaningful between-group differences (mean difference [MD] = 17.26, confidence interval [CI]: 14.29-20.22 and MD = 13.20, CI: 9.45-16.96 on the S-STAI-6, respectively). CONCLUSION: The latent illness representation profiles identified in this study provide support for the role of negative beliefs contributing to anxiety in women testing HPV-positive with normal cytology. Characteristics specific to subgroups of highly anxious women (Profiles 2 and 3) could be used by policymakers to target information in routine patient communications (e.g., test result letters) to reduce unnecessary burden. Future research should adopt longitudinal designs to understand the trajectory of illness representations from HPV diagnosis through to clearance versus persistence.

RESUMO

OBJECTIVES: Many countries are now using primary human papillomavirus (HPV) testing for cervical screening, testing for high-risk HPV and using cytology as triage. An HPV-positive result can have an adverse psychological impact, at least in the short term. In this paper, we explore the psychological impact of primary HPV screening over 12 months. METHODS: Women were surveyed soon after receiving their results (n=1133) and 6 (n=762) and 12 months (n=537) later. Primary outcomes were anxiety (Short-Form State Anxiety Inventory-6) and distress (General Health Questionnaire-12). Secondary outcomes included concern, worry about cervical cancer and reassurance. Mixed-effects regression models were used to explore differences at each time point and change over time across four groups according to their baseline result: control (HPV negative/HPV cleared/normal cytology and not tested for HPV); HPV positive with normal cytology; HPV positive with abnormal cytology; and HPV persistent (ie, second consecutive HPV-positive result). RESULTS: Women who were HPV positive with abnormal cytology had the highest anxiety scores at baseline (mean=42.2, SD: 15.0), but this had declined by 12 months (mean=37.0, SD: 11.7) and was closer to being within the 'normal' range (scores between 34 and 36 are considered 'normal'). This group also had the highest distress at baseline (mean=3.3, SD: 3.8, scores of 3+ indicate case-level distress), but the lowest distress at 12 months (mean=1.9, SD: 3.1). At 6 and 12 months, there were no between-group differences in anxiety or distress for any HPV-positive result group when compared with the control group. The control group were less concerned and more reassured about their result at 6 and 12 months than the HPV-positive with normal cytology group. CONCLUSIONS: Our findings suggest the initial adverse impact of an HPV-positive screening result on anxiety and distress diminishes over time. Specific concerns about the result may be longer lasting and efforts should be made to address them.

RESUMO

OBJECTIVES: Low uptake of cervical screening in women in their 50s and 60s leaves them at elevated risk of cancer in older age. An age-targeted intervention could be an effective way to motivate older women to attend cervical screening. Our primary objective was to test the impact of different candidate messages on cervical screening intention strength. DESIGN: A cross-sectional online survey with randomized exposure to different candidate messages. METHODS: Women aged 50-64 years who were not intending to be screened when next invited were recruited through an online panel. Those meeting the inclusion criteria (n = 825) were randomized to one of three groups: (1) control group, (2) intervention group 1, (3) intervention group 2. Each intervention group saw three candidate messages. These included a descriptive social norms message, a diagram illustrating the likelihood of each possible screening outcome, a response efficacy message, a risk reduction message and an acknowledgement of the potential for screening discomfort. We tested age-targeted versions (vs. generic) of some messages. The primary outcome was screening intention strength. RESULTS: After adjusting for baseline intention, social norms (p = .425), outcome expectancy (p = .367), risk reduction (p = .090), response efficacy (p = .136) and discomfort acknowledgement messages (p = .181) had no effect on intention strength. Age-targeted messages did not result in greater intention than generic ones. CONCLUSIONS: There was no evidence that a single message used to convey social norms, outcome expectancy, risk reduction or response efficacy had an impact on intention strength for older women who did not plan to be screened in future.

RESUMO

BACKGROUND: Systematic reviews have identified effective strategies for increasing postal response rates to questionnaires; however, most studies have isolated single techniques, testing the effect of each one individually. Despite providing insight into explanatory mechanisms, this approach lacks ecological validity, given that multiple techniques are often combined in routine practice. METHODS: We used a two-armed parallel randomised controlled trial (n = 2702), nested within a cross-sectional health survey study, to evaluate whether using a pragmatic combination of behavioural science and evidenced-based techniques (e.g., personalisation, social norms messaging) in a study invitation letter increased response to the survey, when compared with a standard invitation letter. Participants and outcome assessors were blinded to group assignment. We tested this in a sample of women testing positive for human papillomavirus (HPV) at cervical cancer screening in England. RESULTS: Overall, 646 participants responded to the survey (response rate [RR] = 23.9%). Logistic regression revealed higher odds of response in the intervention arm (n = 357/1353, RR = 26.4%) compared with the control arm (n = 289/1349, RR = 21.4%), while adjusting for age, deprivation, clinical site, and clinical test result (aOR = 1.30, 95% CI: 1.09-1.55). CONCLUSION: Applying easy-to-implement behavioural science and evidence-based methods to routine invitation letters improved postal response to a health-related survey, whilst adjusting for demographic characteristics. Our findings provide support for the pragmatic adoption of combined techniques in routine research to increase response to postal surveys. TRIAL REGISTRATION: ISRCTN, ISRCTN15113095 .

RESUMO

BACKGROUND: Due to an increased risk of sexually transmitted infections (STIs), gay, bisexual and other men who have sex with men (MSM) have been recommended to receive vaccinations against human papillomavirus, meningitis C and hepatitis A/B. This review aimed to compare the rates of vaccine acceptability, uptake and completion, and to identify determinants of vaccine outcomes specific to MSM to inform a theoretical framework. METHODS: In January 2020 four databases were explored to identify vaccination behaviours and associated factors among MSM. A narrative systematic review and meta-analysis were performed. Data were synthesised for theoretical modelling. RESULTS: Seventy-eight studies, mostly from the USA, were included. The average vaccine acceptability was 63% (median = 72%, range: 30%-97%), vaccine uptake 45% (median = 42%, range: 5%-100%) and vaccine completion 47% (median = 45%, range: 12%-89%). Six categories of factors associated with vaccination acceptability, uptake and completion were conceptualised: Individual (e.g., demographic and psychosocial); Interpersonal (e.g., peer education); Healthcare provider (e.g., vaccine recommendation); Organisational and practice setting (e.g., routine collection of patient sexual orientation information that is integrated into a clinical decision support system); Community environment (e.g., targeted health promotion campaigns); and National, state and local policy environment (e.g., public health guidelines targeting MSM). CONCLUSION: Despite overall high levels of acceptability, uptake and completion rates were below targets predicted by cost-effectiveness modelling across all recommended vaccines. These parameters may need to be adjusted for more precise estimations of cost-effectiveness. Addressing the multiple levels of determinants, as outlined in our theoretical framework, will help guide interventions to increase vaccine completion among MSM.

RESUMO

Tens-of-millions of women every year test positive for human papillomavirus (HPV) at routine cervical screening. We performed a mixed-methods systematic review using a results-based convergent design to provide the first comprehensive overview of emotional response to testing positive for HPV (HPV+). We mapped our findings using the cognitive behavioural framework. Six electronic databases were searched from inception to 09-Nov-2019 and 33 papers were included. Random-effects meta-analyses revealed that HPV+ women with abnormal or normal cytology displayed higher short-term anxiety than those with normal results (MD on State-Trait Anxiety Inventory = 7.6, 95% CI: 4.59-10.60 and MD = 6.33, CI: 1.31-11.35, respectively); there were no long-term differences. Psychological distress (general/sexual/test-specific) was higher in HPV+ women with abnormal cytology in the short-term and long-term (SMD = 0.68, CI: 0.32-1.03 and SMD = 0.42, CI: 0.05-0.80, respectively). Testing HPV+ was also related to disgust/shame, surprise and fear about cancer. Broadly, adverse response related to eight cognitive constructs (low control, confusion, cancer-related concerns, relationship concerns, sexual concerns, uncertainty, stigma, low trust) and six behavioural constructs (relationship problems, social impact, non-disclosure of results, idiosyncratic prevention, indirect clinical interaction, changes to sexual practice). Almost exclusive use of observational and qualitative designs limited inferences of causality and conclusions regarding clinical significance.

RESUMO

OBJECTIVE: To explore reasons for variations in anxiety in women testing positive for human papillomavirus (HPV) with normal cytology at routine HPV primary cervical cancer screening. METHODS: In-depth interviews were conducted with 30 women who had tested HPV-positive with normal cytology, including 15 with low-to-normal anxiety and 15 with high anxiety. Data were analysed using Framework Analysis to compare themes between low and high anxiety groups. RESULTS: Several HPV-related themes were shared across anxiety groups, but only highly anxious women expressed fear and worry, fatalistic cognitions about cancer, fertility-related cognitions, adverse physiological responses and changes in health behaviour(s). In comparison to those with low anxiety, women with high anxiety more strongly voiced cognitions about the 12-month wait for follow-up screening, relationship infidelity, a lower internal locus of control and HPV-related symptom attributions. CONCLUSIONS: Receiving an HPV-positive with normal cytology result related to various emotional, cognitive, behavioural and physiological responses; some of which were specific to, or more pronounced in, women with high anxiety. If our observations are confirmed in hypothesis-driven quantitative studies, the identification of distinct themes relevant to women experiencing high anxiety can inform targeted patient communications and HPV primary screening implementation policy.

RESUMO

BACKGROUND: Human papillomavirus (HPV)-based cervical screening is now replacing cytology-based screening in several countries and many women in screening programmes will consequently receive HPV-positive results. Because of the sexually transmitted nature of HPV, receiving an HPV-positive result may raise questions about disclosing the infection to a sexual partner. OBJECTIVE: To review the quantitative and qualitative literature exploring women's concerns about disclosing a high-risk cervical HPV infection to a sexual partner. METHODS: We searched MEDLINE, PsycINFO, CINAHL Plus, Web of Science and EMBASE for studies reporting at least one disclosure-related outcome among women with high-risk HPV. We also searched the grey literature and carried out forward/backward citation searches. A narrative synthesis for quantitative studies and a thematic synthesis for qualitative studies were conducted. RESULTS: Thirteen articles met the inclusion criteria (12 qualitative, 1 quantitative). In the quantitative study, 60% of HPV-positive women felt disclosing an HPV result was 'risky'. Concerns about disclosing HPV to a sexual partner were influenced by the stigma that is associated with having an STI and uncertainty about how their partner would respond. Women questioned how, when and to whom they should disclose their HPV-positive status. CONCLUSIONS: The studies included in this review provide rich information about the range of concerns women have, the reasons for these concerns, and the questions women have about disclosing HPV to sexual partners. As studies were predominantly qualitative, the prevalence of concerns is unclear.

RESUMO

We used a cross-sectional survey to examine short-term anxiety and distress in women receiving different results following routine human papillomavirus (HPV) primary testing at cervical screening. Participants were women aged 24-65 (n = 1,127) who had attended screening at one of five sites piloting HPV primary screening in England, including a control group with normal cytology who were not tested for HPV. Women completed a postal questionnaire ~2 weeks after receiving their screening result. Unadjusted mean anxiety scores ranged from 32.9 (standard deviation [SD] = 12.2) in HPV-negative women to 42.1 (SD = 14.9) in women who were HPV-positive with abnormal cytology. In adjusted analyses, anxiety was significantly higher in women testing HPV-positive with either normal cytology (mean difference [MD] = 3.5, CI: 0.6-6.4) or abnormal cytology (MD = 7.2, CI: 3.7-10.6), than the control group. Distress was slightly higher in women who tested HPV-positive with abnormal cytology (MD = 0.9, CI: 0.02-1.8), than the control group. We also found increased odds of very high anxiety in women who tested HPV-positive with normal or abnormal cytology compared to the control group. This pattern of results was only observed among women receiving their first HPV-positive result, not among women found to have persistent HPV at 12-month follow-up. Testing HPV-positive with normal cytology for the first time, is associated with elevated anxiety despite carrying very low immediate cervical cancer risk. However, receiving the same test result at 12-month early recall does not appear to be associated with higher anxiety, suggesting anxiety may normalise with repeated exposure and/or over time.

RESUMO

OBJECTIVES: Uptake of cervical screening among women aged 50-64 years is declining. Not feeling at risk because of current sexual behaviour is a reason some older women give for not being screened. We hypothesised that explaining the long interval between acquiring human papillomavirus (HPV) and developing cervical cancer would increase the relevance of screening in older women. METHODS: Women aged 50-64 years (n=597) who did not intend to go for screening were recruited through an online panel and randomised to one of three information conditions: cause only (basic information about HPV and cervical cancer), cause with basic timeline (also read a sentence describing the long interval between acquiring HPV and developing cervical cancer) and cause with explicit timeline (read the same as the timeline group alongside an explanation of what this means for older women). Perceived risk of cervical cancer, screening intention strength and understanding of HPV were assessed preinformation and postinformation exposure. RESULTS: Information condition was significantly associated with risk perceptions and intention strength postintervention (F(2,593)=6.26, p=0.002 and F(2,593)=4.98, p=0.007 respectively). Women in the cause with explicit timeline condition were more likely to increase their risk perceptions and intention strength compared with cause only (24% vs 9% and 25% vs 13% for risk perceptions and intention, respectively). In the cause with explicit timeline group, women with 4-10 lifetime partners had higher odds of increasing their perceived risk and intention strength postintervention compared with those with 0-1 partners (OR=2.27, 95% CI 1.01 to 5.12 and OR=3.20, 95% CI 1.34 to 7.67, respectively). CONCLUSIONS: Providing a clear explanation that decouples women's perceived cervical cancer risk from their current sexual behaviour has the potential to increase perceived risk of cervical cancer and intentions to be screened among older women. Providing women with a clear cognitive representation of the aetiology of cervical cancer may be one approach to increasing screening uptake.
