Factors Influencing the Experience of Breast and Cervical Cancer Screening Among Women in Low- and Middle-Income Countries: A Systematic Review

Prevalence of Breast Cancer Screening in Asia: Systematic Review and Meta-Analysis

BACKGROUND

Breast cancer is one of the leading causes of cancer-related mortality among women above 50 years of age. This systematic review and meta-analysis aimed at identifying the prevalence and trend of breast cancer screening among selected Asian countries.

METHODS

We searched three databases including, PubMed, Web of Science, and Scopus using our search terms. Two independent reviewers screened titles and abstracts applying the inclusion and exclusion criteria specified in the PROSPERO (registration ID: CRD42023401516) and any conflicts were resolved through discussion. Two independent reviewers and conflicts also completed the full-text screening, which was solved. Relevant information was extracted in an Excel sheet and random effects meta-analysis was performed to identify the pooled estimate of breast cancer screening in Asia using Stata 17.

RESULTS

We identified 41 studies from 14 selected Asian countries reporting breast cancer screening rates from 2012-2023. The pooled estimate of four countries (China, Iran, Japan, and Korea) with more than three data points on clinical breast examination and mammographic screening showed a screening rate of 24% (95% CI: 0.20 - 0.27) and 18% (95% CI: (0.14 - 0.21) in the last ten years respectively.

CONCLUSION

Most Asian countries do not have sufficient data on breast cancer screening due to a lack of nationally representative surveys or national-level cancer registries. Therefore, it is crucial to strengthen cancer control policies including breast cancer screening programs.

Drivers of breast cancer and cervical cancer screening among women of reproductive age: insights from the Ghana Demographic and Health Survey

BACKGROUND

The two major causes of cancer-related deaths among women in Ghana are breast cancer (BC) and cervical cancer (CC). These types of cancers typically do not show any symptoms until they have progressed. Therefore, it is important to screen for early detection. This research aimed to investigate the rate of breast cancer and cervical cancer screening, as well as the factors associated with it, among women of reproductive age in Ghana.

METHODS

This study analysed data from the 2022 Ghana Demographic and Health Survey. A total of 15,014 women aged 15 to 49 years were included in the analysis. Descriptive statistics and binary logistic regression were employed to analyse the data with the aid of STATA/SE, version 17.

RESULTS

It was found that 18.4% and 5.0% of the women had screened for BC and CC, respectively. Women aged 45-49 years were about three times more likely (aOR = 2.83, 95% CI: 1.88-4.24) to screen for BC compared to those aged 15-19 years. Women who had tested for HIV had increased odds (aOR = 1.88, 95% CI: 1.56-2.25) of screening for BC compared to their counterparts. Women within the richest wealth index (aOR = 1.95, 95% CI: 1.40-2.72) had increased odds of screening for BC compared to those in the poorest wealth index. Regarding CC screening, women with higher education (aOR = 2.56, 95% CI: 1.53-4.29) were two times more likely to screen for CC compared to those with no formal education. Women who did not use tobacco (aOR = 0.45, 95% CI: 0.21-0.96) had decreased odds of CC screening compared to their counterparts.

CONCLUSIONS

This study showed that the uptake of BC and CC screening services among women in Ghana was very low. The drivers of BC and CC screening included enabling, predisposing, and need factors. Stakeholders can leverage the mass media to raise awareness and educate women in reproductive age about the importance of BC and CC screening. This study provides relevant information that can inform BC and CC policies and programmes in Ghana.

Cost-utility and budget impact analyses of cervical cancer screening using self-collected samples for HPV DNA testing in Thailand

INTRODUCTION

Cervical cancer ranks as the third most prevalent cancer among women in Thailand. However, the effectiveness of cervical cancer screening programs is limited by several factors that impede the screening rate. The utilization of self-collected samples for screening purposes has the potential to alleviate barriers to screening in Thai women. This study assessed the cost-utility and budget impact of implementing cervical cancer screening using self-collected samples for human papillomavirus (HPV) deoxyribonucleic acid (DNA) testing in Thailand.

MATERIALS AND METHODS

We employed a decision tree integrated with a Markov model to estimate the lifetime costs and health benefits associated with the cervical cancer screening program for women aged 25-65. The analysis was conducted from a societal perspective. Four screening policy options were compared: (1) additional self-collected samples for HPV DNA testing, (2) clinician-collected samples for HPV DNA testing only, (3) clinician-collected samples for cytology test (i.e., status quo), and (4) no screening. The model inputs were based on unvaccinated women. The screening strategies and management in those with positive results were assumed followed to the Thai clinical practice guideline. Costs were reported in 2022 Thai baht. Sensitivity analyses were conducted. The ten-year budget impacts of the additional self-collected samples for HPV DNA testing were calculated from a payer perspective.

RESULTS

All screening policies were cost-saving compared to no screening. When comparing the additional self-collected samples for HPV DNA testing with the clinician-collected samples policy, it emerged as the dominant strategy. The incremental benefit in cervical cancer prevention achieved by incorporating self-collected samples for screening was observed at any additional screening rate that could be achieved through their use. Sensitivity analyses yielded consistently favorable results for the screening policies. The average annual budget impact of the additional self-collected samples for screening policy amounted to 681 million Thai baht. This budget allocation could facilitate cervical cancer screening for over 10 million women.

CONCLUSIONS

An addition of self-collected samples for HPV DNA testing into the cervical cancer screening program is cost-saving. The benefits of this screening policy outweigh the associated incremental costs. Policymakers should consider this evidence during the policy optimization process.

Patients' experiences undergoing breast evaluation in Rwanda's Women's Cancer Early Detection Program

PURPOSE

There is urgent need for interventions to facilitate earlier diagnosis of breast cancer in low- and middle-income countries where mammography screening is not widely available. Understanding patients' experiences with early detection efforts, whether they are ultimately diagnosed with cancer or benign disease, is critical to optimize interventions and maximize community engagement. We sought to understand the experiences of patients undergoing breast evaluation in Rwanda's Women's Cancer Early Detection Program (WCEDP).

METHODS

We conducted in-person semi-structured interviews with 30 patients in two districts of Rwanda participating in the WCEDP. Patients represented a range of ages and both benign and malignant diagnoses. Interviews were recorded, transcribed, translated, and thematically analyzed.

RESULTS

Participants identified facilitators and barriers of timely care along the breast evaluation pathway. Community awareness initiatives were facilitators to care-seeking, while persistent myths and stigma about cancer were barriers. Participants valued clear clinician-patient communication and emotional support from clinicians and peers. Poverty was a major barrier for participants who described difficulty paying for transport, insurance premiums, and other direct and indirect costs of hospital referrals in particular. COVID-19 lockdowns caused delays for referred patients. Although false-positive clinical breast exams conferred financial and emotional burdens, participants nonetheless voiced appreciation for their experience and felt empowered to monitor their own breast health and share knowledge with others.

CONCLUSION

Rwandan women experienced both benefits and burdens as they underwent breast evaluation. Enthusiasm for participation was not reduced by the experience of a false-positive result. Reducing financial, logistical and emotional burdens of the breast diagnostic pathway through patient navigation, peer support and decentralization of diagnostic services could improve patients' experience.

Recognising socio-cultural barriers while seeking early detection services for breast cancer: a study from a Universal Health Coverage setting in India

BACKGROUND

Breast cancer is the commonest cancer among women in India, yet the uptake of early detection programs is poor. This leads to late presentation, advanced stage at the time of diagnosis, and high mortality. Poor accessibility and affordability are the most commonly cited barriers to screening: we analyse socio-cultural factors influencing the uptake of early detection programmes in a Universal Health Coverage (UHC) setting in India, where geographical and financial barriers were mitigated.

METHODS

Two hundred seventy-two women engaging in an awareness-based early detection program were recruited by randomization as the participant (P) group. A further 272 women who did not participate in the early detection programme were recruited as non-participants (NP). None of the groups were previously screened for breast cancer. Interviews were conducted using a 19-point questionnaire, consisting of closed-ended questions regarding demographics and social, cultural, spiritual and trust-related barriers.

RESULTS

The overall awareness about breast cancer was high among both groups. None of the groups reported accessibility-related barriers. Participants were more educated (58.09% vs 47.43%, p = 0.02) and belonged to nuclear families (83.59% vs 76.75%, p = 0.05). Although they reported more fear of isolation due to stigma (25% vs 14%, p = 0.001), they had greater knowledge about breast cancer and trust in the health system compared to non-participants.

CONCLUSIONS

The major socio-cultural barriers identified were joint family setups, lower education and awareness, and lack of trust in healthcare professionals. As more countries progress towards UHC, recognising socio-cultural barriers to seeking breast health services is essential in order to formulate context-specific solutions to increase the uptake of early detection and screening services.
