Perceived cervical cancer risk among women treated for high-grade cervical intraepithelial neoplasia: The importance of specific knowledge

Determination of the Relationship Between Gynecological Cancer Awareness and Fear of Cancer in Women Using Social Media and the Affecting Factors

BACKGROUND

Understanding the relationship between fear of gynecological cancer and awareness of cancer in women may help oncology nurses increase women's participation in gynecological cancer screening.

OBJECTIVE

To examine the relationship between women's gynecological cancer awareness and cancer fear using social media and the affecting factors.

METHODS

In a descriptive and cross-sectional study design, online data were collected from 1231 women aged 20 to 69 years through social media using the Descriptive Information Form, the Gynecological Cancer Awareness Scale (GCAS), and the Cancer Worry Scale (CWS). Analytic tests included paired t tests, analysis of variance, and post hoc correlations and structural equation modeling.

RESULTS

The women's total mean GCAS score was above moderate (152 ± 17), and their mean CWS score was high (19 ± 5). There was no relationship between the GCAS and CWS mean scores. Characteristics of participants with high awareness of gynecological cancer were being young, having a high educational level, having children, living in a province, having a history of cancer or family history of cancer, and having regular gynecological examinations, Papanicolaou smear tests, breast self-examination, and vulva examinations ( P < .05). The fear of cancer was higher in women with children, a family history of cancer, and regular gynecological examination behaviors ( P < .05).

CONCLUSION

Awareness of gynecological cancer was not significantly statistically associated with fear of cancer. Certain sociodemographic and gynecological characteristics are associated with awareness of gynecological cancer and/or fear of cancer.

IMPLICATIONS FOR PRACTICE

Oncology nurses may plan individualized or large-scale educational events that may make use of social media to enhance accurate awareness of gynecological cancer and related examinations in women.

Knowledge of Thai women in cervical cancer etiology and screening

Knowledge about cervical cancer screening and Human papilloma virus (HPV) influence on their awareness to the cervical cancer screening program. Most previous studies found inadequate knowledge and attitude among healthy women affect the low rate of screening. This study aimed to assess knowledge of cervical cancer screening and HPV in women who had abnormal cervical cancer screening in Bangkok. Thai women, aged ≥ 18 years old, who had abnormal cervical cancer screening and scheduled to colposcopy clinics of 10 participating hospitals were invited to participate in this cross-sectional study. The participants were asked to complete a self-answer questionnaire (Thai language). The questionnaire composed of 3 parts: (I) demographic data, (II) knowledge about cervical cancer screening and (III) knowledge about HPV. Among 499 women who answered the questionnaires, 2 had missing demographic data. The mean age of the participants was 39.28 ± 11.36 years. 70% of them had experience of cervical cancer screening, with 22.7% had previous abnormal cytologic results. Out of 14 questions, the mean score of knowledge about cervical cancer screening was 10.04 ± 2.37. Only 26.9% had good knowledge about cervical cancer screening. Nearly 96% of woman did not know that screening should be done. After excluding 110 women who had never known about HPV, 25.2% had good knowledge about HPV. From multivariable analysis, only younger age (≤ 40 years) was associated with good knowledge of cervical cancer screening and HPV. In the conclusion, only 26.9% of women in this study had good knowledge regarding cervical cancer screening. Likewise, 20.1% of women who had ever heard about HPV has good knowledge about HPV. Providing information about cervical cancer screening and HPV should improve the women's knowledge and better adherence to the screening procedure.

Age, margin status, high-risk human papillomavirus and cytology independently predict recurrent high-grade cervical intraepithelial neoplasia up to 6 years after treatment

The present study aimed to identify the factors that independently contribute to disease recurrence among women first-time treated for high-grade cervical intraepithelial neoplasia (CIN) during 4–6 years of follow-up. Overall, 529 of 530 eligible patients participated; these patients all attended a 1st follow-up appointment ~6 months post-conization, at which time high-risk human-papillomavirus (HPV) testing, liquid-based cytology and colposcopy were performed. Full data on margin excision status, other aspects of initial treatment and comorbidity were obtained. At least one subsequent follow-up was attended by 88% of patients. A total of 22 recurrent cases were detected during follow-up. Detected recurrence was the outcome of focus for multiple logistic regression analysis, with odds ratios (OR) and 95% confidence intervals (CI) computed. Four significant independent risk factors were identified: Age 45 years or above (OR=3.5, 95% CI=1.3–9.9), one or both unclear or uncertain margins (OR=5.3, 95% CI=2.0–14.2), positive HPV at 1st follow-up (OR=5.8, 95% CI=2.0–16.8), and abnormal cytology at 1st follow-up (OR=3.9, 95% CI=1.4–11.0). Bivariate analysis revealed that persistent HPV positivity was associated with recurrence (P<0.01). These findings indicated that incomplete excision of the CIN lesion may warrant more intensive subsequent screening, regardless of early post-conization HPV findings. Although early post-conization positive HPV was a powerful, independent predictor of recurrent high-grade CIN, over one-third of the patients with detected recurrence had a negative early post-conization HPV finding. These patients returned for routine screening, at which time, in most cases, HPV status was positive, thus indicating the need for repeated HPV evaluation. Especially during the on-going pandemic, home vaginal self-sampling is recommended. Particular attention is required for women aged ≥45 years. In addition, although not statistically significant, relevant comorbidities, especially autoimmune conditions, warrant consideration in clinical decision-making. Women who have been treated for high-grade CIN are at risk for recurrent disease and progression to cervical cancer; therefore, they require careful, individualized follow-up to avoid these adverse consequences.

Acceptance of Self-Sampling Among Long-Term Cervical Screening Non-Attenders with HPV-Positive Results: Promising Opportunity for Specific Cancer Education

This study aims to investigate acceptance of vaginal self-sampling for high-risk human papilloma virus (HPV) among long-term screening non-attenders at increased cervical cancer risk and to identify leverage points to promote screening adherence among these women. Forty-three long-term screening non-attenders performed home vaginal self-sampling for HPV, had positive HPV results, and subsequently attended gynecologic examination. Sixteen (37.2%) had high-grade cervical intraepithelial neoplasia (CIN2 or 3), and two had invasive cervical cancer. Forty-one of these women completed a questionnaire concerning Specific Knowledge about HPV, CIN, and cervical cancer, potential barriers to screening and views about self-sampling. Results were compared with 479 women treated for CIN2+ who attended gynecologic follow-up and also performed self-sampling. Significant multivariate predictors of long-term non-attender status compared with referents were low Specific Knowledge, high confidence in self-sampling, and potential barriers-refraining from activity to attend gynecologic examination, needing another's help to attend, and long travel time. Non-attenders citing fear/refraining from gynecologic examination as why they preferred self-sampling significantly more often had lowest Specific Knowledge compared with other non-attenders. All non-attenders could envision themselves doing self-sampling again while only 74% of referents endorsed this statement (p = 0.0003). We conclude that HPV self-sampling is an acceptable option for women at increased cervical cancer risk who have been long-term screening non-attenders. Educational outreach to enhance Specific Knowledge about HPV, CIN and cervical cancer is critical. Those non-attenders who explicitly avoid gynecologic examinations need special attention.

Self-sampling for high-risk human papillomavirus as a follow-up alternative after treatment of high-grade cervical intraepithelial neoplasia

Women treated for high-grade cervical-intraepithelial-neoplasia (CIN) require long-term follow-up with high-risk human-papillomavirus (HPV) testing. Self-sampling for HPV is well-accepted among these patients, but its role in follow-up for this group requires investigation. The present study examined how well HPV findings from self-sampled vaginal (VSS) and urine specimens correctly identified women from this cohort with recurrent CIN2+ compared with samples collected by clinicians. At 1st post-conization follow-up, 531 patients (99.8% participation) gave urine samples, performed VSS, underwent colposcopy with punch biopsy of visible lesions and clinician-collected cervical sampling for HPV analysis and liquid-based cytology. A total of 113 patients with positive HPV and/or abnormal cytology at 1st follow-up underwent 2nd follow-up. At 1st follow-up, all patients with recurrent CIN3 had positive HPV results by all methods. Clinician sampling and VSS revealed HPV16 positivity in 50% of recurrent cases and urine sampling revealed HPV16 positivity in 25% of recurrent cases. At 2nd follow-up, all 7 newly-detected CIN2/3 recurrences were associated with HPV positivity on VSS and clinician-samples. Only clinician-collected samples detected HPV positivity for two adenocarcinoma-in-situ recurrences, and both were HPV18 positive. A total of 77 patients had abnormal cytology at 1st follow-up, for which HPV positivity via VSS yielded highest sensitivity. The HPV findings were positive from VSS in 12 patients with high-grade squamous-intraepithelial-lesions (HSIL), and 11 patients with HSIL had positive HPV findings in clinician-collected and urine samples. All methods for assessing HPV presence yielded significant age-adjusted odds ratios for predicting abnormal lesions at 1st follow-up. For overall HPV results, Cohen's kappa revealed substantial agreement between VSS and clinician sampling, and moderate agreement between urine and clinician sampling. Clinician sampling and VSS were highly concordant for HPV16. Insofar as the pathology was squamous (not glandular), VSS appeared as sensitive as clinician sampling for HPV in predicting outcome among the present cohort. Since VSS can be performed at home, this option can maximize participation in the required long-term follow-up for these women at high-risk.

Health care informational challenges for women diagnosed with cervical intraepithelial neoplasia: a qualitative study

Background

Internationally, women with cervical intraepithelial neoplasia (CIN) lack knowledge about their disease, which limits their ability to take responsibility for self-care and creates negative psychosocial effects, including marital problems. Normally, screening is performed in primary care, and in case of abnormal results, the patient is referred to specialized care for follow-up and treatment. Given the lack of international literature regarding patients’ experiences in primary and specialized healthcare, our study aims to: (a) investigate how women with CIN perceive the communication and management of information by healthcare providers at different moments of their healthcare and (b) identify these women’s informational needs.

Methods

A qualitative exploratory study was carried out in a gynecology unit of a public hospital of the Galician Health Care Service (Spain). Participants were selected through purposive sampling. The sample consisted of 21 women aged 21 to 52 years old with a confirmed diagnosis of CIN. Semistructured interviews were recorded and transcribed. A thematic analysis was carried out, including triangulation of researchers for analysis verification.

Results

Two analytical themes were identified. The first was communication gaps in the diagnosis and management of information in primary and specialized healthcare. These gaps occurred in the following moments of the healthcare process: (a) cervical cancer screening in primary care, (b) waiting time until referral to specialized care, (c) first consultation in specialized care, and (d) after consultation in specialized care. The second theme was participants’ unmatched informational needs. The doubts and informational needs of women during their healthcare process related to the following subthemes: (a) HPV transmission, (b) HPV infection symptoms and consequences, and (c) CIN treatment and follow-up.

Conclusions

This study shows that women who have a diagnosis of CIN experience important healthcare informational challenges when accessing primary and specialized care that have several implications for their wellbeing. The information given is limited, which makes it difficult for women to understand and participate in the decision making regarding the prevention and treatment of CIN. Service coordination among different levels of care and the availability of educational materials at any given time would improve the patients’ healthcare experience.

Risk factors and relationship between screening periodicity and risk of cervical cancer among nurses and midwives. A cross-sectional study

BACKGROUND

If nurses and midwives undergo cervical cancer screening regularly, they can become role models for other women regarding this screening.

OBJECTIVES

The aims here were (i) to determine factors associated with undergoing cervical cancer screening; and (ii) to examine the association of cervical cancer screening periodicity with cervical cancer risk levels among nurses and midwives.

DESIGN AND SETTING

Cross-sectional study in a public hospital.

METHODS

466 nurses and midwives participated in this study. The relationships between undergoing Pap smear screening and sociodemographic characteristics, cervical cancer risk factors, perception of cervical cancer risk and calculated cervical cancer risk levels were examined. Cervical cancer risk levels were determined using the "Your Disease Risk" assessment tool (Washington University).

RESULTS

35% of the nurses and midwives had undergone Pap smear testing at least once in their lifetimes. The odds of having undergone Pap smear testing were higher among smokers (odds ratio, OR: 2.08; 95% confidence interval, CI: 1.24-3.48) and among those who perceived their risk of cervical cancer to be high (OR: 3.60; 95% CI: 1.36-9.51). The frequency of undergoing Pap smear testing at least once in a lifetime was higher among primiparae (OR: 17.99; 95% CI: 6.36-50.84) and secundiparae (OR: 41.53; 95% CI: 15.01-114.91) than among nulliparae. No relationship was found between Pap smear test periodicity and calculated risk level.

CONCLUSION

There is a need to assess motivational barriers that might lead to low levels of Pap smear screening among nurses and midwives who are role models for women regarding cervical cancer prevention.

Knowledge, attitudes and awareness of the human papillomavirus among health professionals in New Zealand

Background

Human papillomavirus (HPV) is a common sexually transmitted infection that is implicated in 99.7% of cervical cancers and several other cancers that affect both men and women. Despite the role that HPV plays in an estimated 5% of all cancers and the evolving role of HPV vaccination and testing in protecting the public against these cancers, preliminary research in New Zealand health professionals suggest knowledge about HPV may not be sufficient.

Methods

A total of 230 practice nurses, smear takers and other clinical and laboratory staff who attended a range of training events completed a cross-sectional survey between April 2016 and July 2017. The survey explored four broad areas: demographics and level of experience, HPV knowledge (general HPV knowledge, HPV triage and test of cure (TOC) knowledge and HPV vaccine knowledge), attitudes towards the HPV vaccine and self-perceived adequacy of HPV knowledge.

Results

The mean score on the general HPV knowledge questions was 13.2 out of 15, with only 25.2% of respondents scoring 100%. In response to an additional question, 12.7% thought (or were unsure) that HPV causes HIV/AIDS. The mean score on the HPV Triage and TOC knowledge questions was 7.4 out of 10, with only 9.1% scoring 100%. The mean score on the HPV vaccine knowledge questions was 6.0 out of 7 and 44.3% scored 100%. Only 63.7% of respondents agreed or strongly agreed that they were adequately informed about HPV, although 73.3% agreed or strongly agreed that they could confidently answer HPV-related questions asked by patients. Multivariate analyses revealed that knowledge in each domain predicted confidence in responding to patient questions. Furthermore, the number of years since training predicted both HPV knowledge and Triage and TOC knowledge.

Discussion

Although overall level of knowledge was adequate, there were significant gaps in knowledge, particularly about the role of HPV testing in the New Zealand National Cervical Screening Programme. More education is required to ensure that misinformation and stigma do not inadvertently result from interactions between health professionals and the public.

Impact of the human papillomavirus status on the development of high-grade cervical intraepithelial neoplasia in women negative for intraepithelial lesions or malignancy at the baseline: A 9-year Swedish nested case-control follow-up study

BACKGROUND

The causal relation between high-risk human papillomavirus (HPV) and cervical cancer and its precursor lesions has led to the use of sensitive HPV molecular tests for screening. This study examined the impact of the baseline HPV status on the future risk of cervical intraepithelial neoplasia grade 2 or worse (CIN2+) among women with cytology negative for intraepithelial lesions or malignancy (NILM).

METHODS

This was a nested case-control study including women with NILM baseline cytology participating in the Swedish cervical screening program in 2005-2007. Ninety-six cases of CIN2+ and 5 age-matched controls per case were identified through the National Cervical Screening Registry by follow-up through 2014. Baseline liquid-based cytology samples were tested for HPV. Conditional logistic regression analysis was used to calculate odds ratios (ORs) with confidence intervals (CIs).

RESULTS

The risk of future high-grade cervical intraepithelial neoplasia (CIN) was strongly associated with the baseline HPV status. For women younger than 30 years, HPV-16/18 showed a significant association with future risk for CIN2+ (OR, 9.44; 95% CI, 3.37-26.4). Other HPV types were not significantly associated with future CIN2+ in these younger women. For women 30 years old or older, both HPV-16/18 and other HPV subtypes conferred a significant risk.

CONCLUSIONS

The presence of HPV-16/18 among women with NILM cytology is associated with an elevated future risk of high-grade CIN. HPV types other than HPV-16/18 seem to have a greater impact on women 30 years old or older than younger women. Women with NILM cytology and HPV-16/18 need specific follow-up management within screening.

Is self-sampling to test for high-risk papillomavirus an acceptable option among women who have been treated for high-grade cervical intraepithelial neoplasia?

Objective

Self-sampling to test for high risk human papilloma virus (HPV) is becoming an increasingly important component of cervical cancer screening. The aim of this observational study is to examine how women treated for high-grade cervical intraepithelial neoplasia (CIN) view HPV self-sampling.

Methods

Invited to participate in the present study were patients who had undergone treatment of high-grade CIN (grade 2 or higher) and were followed-up at 6-months at the Karolinska University Hospital, Stockholm. The participants were instructed as to how to perform HPV self-sampling. Thereafter, the participants completed a questionnaire about HPV self-sampling and other cervical cancer screening methods, as well as about self-perceived risk of cervical cancer without regular gynecologic follow-up and about specific knowledge regarding HPV, CIN and cervical cancer.

Results

Altogether 479 women enrolled in this study. The participation rate was 96.6%. Nearly 75% of the participants stated they would consider performing the HPV self-sampling prior to their next gynecologic follow-up. Confidence in HPV self-sampling was a significant independent predictor of willingness to perform HPV self-sampling. However, confidence in HPV self-sampling was significantly lower than confidence in Papanicolaou smears and in HPV testing with samples collected by health professionals. Higher specific knowledge about HPV, CIN and cervical cancer was also a significant independent predictor of willingness to perform HPV self-sampling, as was having travelled longer distance to attend gynecologic follow-up. Participants with lower income and without completed university education expressed significantly higher confidence in HPV self-sampling and lower confidence in Papanicolaou smears than the other women.

Conclusions

To the best of our knowledge, this is the first study to examine the views of women treated for high-grade CIN vis-à-vis HPV self-sampling. The latter is an acceptable option for the vast majority of this cohort of women.
