Factors affecting Pap smear uptake in a maternity hospital: A descriptive cross-sectional study

Diagnostic Accuracy of Serum P16ink4A and FOX-P3 Concentrations for Detection of Cervical Lesions Among Women Attending a Cervical Cancer Clinic in Western Uganda: A Case-Control Study

Introduction: Expression of P16ink4A and FOXP3 is correlated with the grades of cervical lesions. In this study, we determined the diagnostic accuracy of serum P16ink4A and FOXP3 concentrations for detection of cervical intraepithelial neoplasia (CIN) and cervical cancer (CC) in a rural setting in Southwestern Uganda. Material and Methods: CIN and CC cases (93 each before treatment), and 93 controls were identified. Clinical and demographic data were documented before quantifying serum P16ink4A and FOXP3 concentrations using quantitative ELISA kits. Cases were confirmed by cytology and/or histology. We employed descriptive statistics, cross-tabulation, and receiver operating curves (ROC) using statistical software for data science (STATA) 17. p-values <0.05 were considered statistically significant. Results: Serum FOXP3 concentration of 0.0545 ng/mL < showed moderate sensitivity (32.22% and 57.78%) for detection of CIN and CC from healthy controls, respectively. It also showed a moderately high specificity of 68.89% for detection of both CIN and CC from healthy controls (AUC-0.6014 and 0.7679, respectively). Serum P16ink4A concentration of 0.946 ng/mL < showed moderate sensitivities (50.00% and 60.00%) and specificities (56.67% and 55.56%) for the detection of CIN and CC from healthy controls, respectively (AUC-0.6085 and 0.7592, respectively). A combination of elevated serum FOXP3 and P16ink4A showed very low sensitivities of 18.89% in detecting CIN from healthy controls and 33.33% for detecting CC from healthy controls. This combination showed high specificity of 83.33% in detecting both CIN and CC from healthy controls (AUC-0.5992 and 0.7642, respectively). Conclusion: Although serum P16ink4A and FOXP3 concentrations showed moderate accuracy, their combination was more specific than sensitive. This combination has a high potential to be applied for diagnosis rather than screening for cervical lesions, at least in the Ugandan population. Combinations of P16ink4A and FOXP3 with other biomarkers could improve diagnostic accuracies. Additionally, studies could be conducted to assess the performance of these biomarkers in the detection of cervical lesions in specific populations, say Human Immunodeficiency Virus (HIV)-positive and HIV-negative populations.

Barriers, facilitators, needs, and preferences in seeking information regarding cervical cancer prevention programs among Turkish, Moroccan, and Syrian immigrant women: a scoping review

BACKGROUND

Cervical cancer (CC) is the fourth most frequently diagnosed cancer in women worldwide. Immigrant women are often disproportionately affected by CC but show low participation in CC screening and human papillomavirus (HPV) vaccination.

METHODS

We conducted a scoping review on immigrant women's information needs regarding CC screening participation and HPV vaccination uptake. A total of 584 articles were found on Embase.com, PsychINFO, and CINAHL, of which 87 articles were included.

RESULTS

This review revealed that immigrant women indicate a need for more personalized information regarding CC screening and HPV vaccination. We identified barriers to obtaining, processing, and understanding the information, which included overall practical, emotional, cultural and religious aspects (e.g., shame, taboo, lack of trust, fatalism, and cultural norms and values regarding sexual activity). Facilitators, such as translation services, receiving information from people with similar cultural and/or religious backgrounds, encouraging other women or family, and using home visits as an outreach strategy, were also identified.

CONCLUSIONS

Our review provides a comprehensive overview of the information needs and preferences of immigrant women, which could be used to tailor interventions, considering the contextual nuances in which these women are situated. The needs and preferences of immigrant women should be taken into account during the development of new information materials or other interventions. This would help immigrant women make informed decisions regarding participation in CC screening and HPV vaccination.

Exploring Factors Influencing Cervical Cancer Screening Participation among Singaporean Women: A Social Ecological Approach

Background/Objectives: Cervical cancer screening uptake in Singapore remains suboptimal. This study employed the Social Ecological Model (SEM) to investigate factors influencing cervical cancer screening participation among Singaporean women. Methods: The study included 665 women, aged 25-69 years, who reported awareness of cancer screening and no personal cancer history. Data were collected through a previously described online survey. Hierarchical logistic regression analysis was conducted to identify significant factors influencing screening participation. Results: Only 30% of participants reported cervical cancer screening participation. Women aged 25-29 years (OR = 0.33; 95% CI = 0.12-0.77), Malay women (OR = 0.42; 95% CI = 0.20-0.83), and unmarried women (OR = 0.30; 95% CI = 0.18-0.48) were less likely to be screened. Positive associations with screening participation were observed with good cervical cancer screening knowledge (OR = 2.90; 95% CI = 1.96-4.32), awareness of primary care providers' role in delivering screening services (OR = 1.94; 95% CI = 1.24-3.10), cancer information seeking behavior (OR = 1.59; 95% CI = 1.07-2.39), and acceptance of self-sampling options (OR = 1.81; 95% CI = 1.22-2.70). Conclusions: Our study highlights the cumulative impact of factors at various SEM levels on screening participation and underscores the necessity for more targeted and multi-pronged strategies to improve cervical cancer screening uptake in Singapore.

FOXP3 serum concentration; a likely predictor of CIN and cervical cancer: Secondary analysis from a case control study at a clinic in South western Uganda

Biomarkers including Forkhead/winged-helix transcription factor box P3 have been proposed in immunohistochemical techniques to diagnose cervical lesions, but can be objectively quantified and measured in blood using methods that can be standardised. In this study we quantified the serum FOXP3 concentrations and assessed their association with cervical lesions at the cervical cancer clinic of Mbarara Regional Hospital (MRRH) Southwestern Uganda. We performed secondary analysis on archived serum samples from a previous unmatched case control study in which we recruited 90 cervical cancer (CC) cases, 90 cervical intraepithelial neoplasia (CIN) cases before any form of treatment and 90 controls. Clinical and demographic data were recorded. We measured FOXP3 concentrations using quantitative ELISA. We performed descriptive statistics and logistic regression in STATA 17 and took P-values of < 0.05 as statistically significant. The mean concentration of FOXP3 was higher in serum samples from CC cases compared with CIN cases and controls, and this difference was statistically significant (P value < 0.001). More than half (52/90,58 %) of serum samples from CC cases had FOXP3 concentrations greater than 0.0545 ng/ml (P value < 0.001). Increase serum FOXP3 expression was not associated with CIN. Increase in serum FOXP3 concentrations were observed to increase the chances of CC by 2 times (OR: 2.094, P value 0.038, 95 % CI: 1.042---4.209). Serum FOXP3 is likely associated with cervical lesions especially CC in our study population. Serum FOXP3 testing may be useful in resource limited settings to aid detection of such lesions given the challenges associated with cytology and VIA. We recommend diagnostic utility studies for circulating FOXP3 as a biomarker for detection of cervical cancer.

"Barriers and Advantages of Self-Sampling Tests, for HPV Diagnosis: A Qualitative Field Experience Before Implementation in a Rural Community in Ecuador"

Introduction

Cervical cancer screening has demonstrated high efficacy in reducing cervical cancer mortality worldwide. However, clinician sampling is often perceived as an uncomfortable procedure that could reduce screening uptake. Self-sampling methods for HPV diagnosis have shown high sensitivity, which could increase acceptance and screening rates among women.

Purpose

This study aims to identify the perceived barriers and advantages of self-sampling methods versus clinician sampling for cervical cancer screening in a rural setting in Ecuador.

Patients and Methods

A qualitative study was conducted. Seven focus group discussions took place in the rural Parish of El Valle in Azuay Province, Cuenca, Ecuador. Women native to this rural area were included in the study. FGDs were recorded and transcribed, and content analysis was performed to categorize and analyze the data.

Results

A total of 45 women participated in the study. Clinician sampling was perceived as a painful and intrusive method. However, participants believed that it is more reliable compared to self-sampling methods, attributing this to the direct visualization of the cervix, which facilitates the detection of cervical pathologies. The perceived advantages of self-sampling included increased comfort, pain reduction, time savings, the ability to perform the test at home, and the potential for widespread availability through pharmacies or local traditional healers. Nevertheless, doubts about the test's reliability as well as the user's proficiency in self-testing posed barriers to the adoption of this technique.

Conclusion

Self-sampling methods offer several advantages over clinician sampling, such as enhanced privacy, comfort, and accessibility to cancer screening. Barriers primarily revolved around users' proficiency in performing the test and the reliability of the results. Providing training for using self-sampling tests could address these barriers.

Application of one-dimensional hierarchical network assisted screening for cervical cancer based on Raman spectroscopy combined with attention mechanism

Cervical cancer is one of the most common malignant tumors among women, and its pathological change is a relatively slow process. If it can be detected in time and treated properly, it can effectively reduce the incidence rate and mortality rate of cervical cancer, so the early screening of cervical cancer is particularly critical and significant. In this paper, we used Raman spectroscopy technology to collect the tissue sample data of patients with cervicitis, Low-grade Squamous Intraepithelial Lesion, High-grade Squamous Intraepithelial Lesion, Well differentiated squamous cell carcinoma, Moderately differentiated squamous cell carcinoma, Poorly differentiated squamous cell carcinoma and cervical adenocarcinoma. A one-dimensional hierarchical convolutional neural network based on attention mechanism was constructed to classify and identify seven types of tissue samples. The attention mechanism Efficient Channel Attention Networks module and Squeeze-and-Excitation Networks module were combined with the established one-dimensional convolutional hierarchical network model, and the results showed that the combined model had better diagnostic performance. The average accuracy, F1, and AUC of the Principal Component Analysis-Squeeze and Excitation-hierarchical network model after 5-fold cross validations could reach 96.49%±2.12%, 0.97±0.03, and 0.98±0.02, respectively, which were 1.58%, 0.0140, and 0.008 higher than those of hierarchical network. The recall rate of the Principal Component Analysis-Efficient Channel Attention-hierarchical network model was as high as 96.78%±2.85%, which is 1.47% higher than hierarchical network. Compared with the classification results of traditional CNN and ResNet for seven types of cervical cancer staging, the accuracy of the Principal Component Analysis-Squeeze and Excitation-hierarchical network model is 3.33% and 11.05% higher, respectively. The experimental results indicate that the model established in this study is easy to operate and has high accuracy. It has good reference value for rapid screening of cervical cancer, laying a foundation for further research on Raman spectroscopy as a clinical diagnostic method for cervical cancer.

Early screening of cervical cancer based on tissue Raman spectroscopy combined with deep learning algorithms

Cervical cancer is the most common reproductive malignancy in the female reproductive system. The incidence rate and mortality rate of cervical cancer among women in China are high. In this study, Raman spectroscopy was used to collect tissue sample data from patients with cervicitis, cervical precancerous low-grade lesions, cervical precancerous high-grade lesions, well differentiated squamous cell carcinoma, moderately differentiated squamous cell carcinoma, poorly differentiated squamous cell carcinoma and cervical adenocarcinoma. The collected data were preprocessed using an adaptive iterative reweighted penalized least squares (airPLS) algorithm and derivatives. Convolutional neural network (CNN) and residual neural network (ResNet) classification models were constructed to classify and identify seven types of tissue samples. The attention mechanism efficient channel attention network (ECANet) module and squeeze-and-excitation network (SENet) module were combined with the established CNN and ResNet network models, respectively, to make the models have better diagnostic performance. The results showed that efficient channel attention convolutional neural network (ECACNN) had the best discrimination, and the average accuracy, recall, F1 and AUC values after five cross-validations could reach 94.04%, 94.87%, 94.43% and 96.86%, respectively.

Religious Denomination, Religiosity, Religious Attendance, and Cancer Prevention. A Systematic Review

Recent research highlighted the influence of religion among health outcomes. To the best of our knowledge, there is no systematic review that summarizes the evidence on the relationship between religious factors and the utilization of cancer screenings. Therefore, this article aims to list the findings about the influence of religious denominations, the importance of religion in one’s life, and religious practices, such as church attendance on the utilization of cancer screenings. PubMed, PsycInfo and CINAHL were searched using a predefined algorithm in June 2020. We included observational studies that examined the association between religion and cancer screening use and employed appropriate items to quantify these key variables. Study selection, data extraction and quality assessment were performed independently by two reviewers. We detected n=27 studies that fulfilled the inclusion criteria. Hereby, n=16 used data from the United States. Most of the studies that were included in our review found a positive association between religious attendance and cancer screening utilization. There was mixed evidence concerning religious denomination as well as religiosity and use of cancer screenings. The studies suggest that religious factors are related to the utilization of cancer screenings. The findings of this systematic review may be helpful to resolve the underuse of cancer screenings by revealing at-risk-groups.

Factors associated with the intention to undergo Pap smear testing in the rural areas of Indonesia: a health belief model

Purposes

This study aimed to understand the influence of health beliefs, demographic factors, and health characteristics on the intention to undergo Pap smear testing among women in rural areas of Indonesia.

Methods

A descriptive cross-sectional study was conducted and 687 married women participated in the study. A convenience sampling was applied to recruit the participants from community health centres in a rural region in Indonesia. Self-reported data using the Health Beliefs Model Scale for Cervical Cancer and Pap Smear Test was collected to assess the health beliefs. Independent t-tests, simple logistic regressions, and a hierarchical logistic regression with 3 steps were run. Statistical significance for analysis was set at p < 0.05.

Results

The mean age of the participants was 42 years (SD = 8.4). Among the participants, 81% of the women had never undergone a Pap smear test, and 61% (n = 422) of the women reported a high intention of receiving a Pap smear test. Income and education Health beliefs regarding Pap smear testing were different between women who had low and high intentions to undergo Pap smear testing. Health beliefs, such as perceived benefits, severity, barriers to Pap smear testing, and health motivation for a Pap smear test were associated with the intention to undergo Pap smear testing among rural Indonesian women. Overall, the hierarchical multiple regression with 3 steps containing demographic, health characteristics, and health belief variables accounted for 31% variance of the intention to undergo Pap smear test among the Indonesian rural women.

Conclusions

Low screening rates of cervical cancer and high intentions to do the screening exist among rural Indonesian women. Health beliefs significantly affect the rural women’s intention of Pap smear testing in Indonesia.

Cervical cancer is a leading cancer among women and a significant cause of mortality for females around the world, including Indonesia. Globally, the screening rate for cervical cancer among women in rural areas remains low. In Indonesia, the incidence and the mortality from cervical cancer remain high compared to other female cancers. The Indonesian government has offered a free Pap smear screening to women since 2014, but the screening rate is still low, around 28%.

A total of 687 married women were included in the study. Approximately 80% of Indonesian women living in rural areas have never undergone a Pap smear test, and 60% of women reported a high intention of receiving a Pap smear test. Education, income, previous experience of Pap smear testing, a friend with a history of cervical cancer, perceived severity, perceived benefits, perceived barriers, and health motivations were significantly associated with the intention of Pap smear testing. Low screening rates of cervical cancer and high intentions toward the cervical cancer screening exist among rural Indonesian women. Health beliefs significantly affect the women’s intention of Pap smear testing.

Barriers to and Facilitators of Cervical Cancer Screening among Women in Southeast Asia: A Systematic Review

In Southeast Asia, cervical cancer is the second most common cancer in women. Low coverage for cervical cancer screening (CCS) becomes a roadblock to disease detection and treatment. Existing reviews on CCS have limited insights into the barriers and facilitators for SEA. Hence, this study aims to identify key barriers and facilitators among women living in SEA. A systematic literature review was conducted on Pubmed, Embase, PsycINFO, CINAHL, and SCOPUS. Primary qualitative and quantitative studies published in English that reported barriers and facilitators to CCS were included. The Mix Methods Appraisal Tool was used for the quality assessment of the included studies. Among the 93 included studies, pap smears (73.1%) were the most common screening modality. A majority of the studies were from Malaysia (35.5%). No studies were from Timor-Leste and the Philippines. The most common barriers were embarrassment (number of articles, n = 33), time constraints (n = 27), and poor knowledge of screening (n = 27). The most common facilitators were related to age (n = 21), receiving advice from healthcare workers (n = 17), and education status (n = 11). Findings from this review may inform health policy makers in developing effective cervical cancer screening programs in SEA countries.
