Using Geospatial Analysis to Identify Priority Communities for Cervical Cancer Prevention in Texas

Introduction

Despite being almost entirely preventable, cervical cancer is the fourth most frequently diagnosed cancer among women worldwide. Cervical cancer incidence suggests missed opportunities for prevention. Geospatial analysis could strategically guide public health interventions. This study aimed to identify geographic clusters of cervical cancer incidence in Texas, a state with higher than national rates of cervical cancer incidence and mortality.

Methods

In this population-based cross-sectional study, the authors analyzed incident cervical cancer data among Texas women aged 30-64 years, from 2014 to 2018. The authors conducted a purely spatial Poisson-based analysis function in SaTScan to examine geographic clusters of higher-than-expected proportions of cervical cancer incidence (i.e., hot spots) and adjusted for age.

Results

A total of 5,060 women aged 30-64 years with incident cervical cancer diagnosis (mean age: 45.7 years, SD=9.6), including 1,840 (36.4%) Hispanic, 591 (11.7%) non-Hispanic Black, 2,397 (47.4%) non-Hispanic White, and 232 (4.6%) other races, were analyzed. Spatial scan analysis detected 7 significant hot spots of cervical cancer incidence. Hot spots were identified in the South Texas Plains (near Mexico border), Gulf Coast (Houston), Prairies and Lakes (North Texas), Panhandle Plains (Northwest Texas), and Piney Woods (Southeast Texas) regions of Texas. Hot spots, compared with the rest of Texas, had higher proportions of Hispanic population and individuals with socioeconomic disadvantages.

Conclusions

This study found spatial variation in cervical cancer incidence in Texas. The hot spot areas can benefit from targeted, novel, scalable, and cost-effective interventions to increase human papillomavirus vaccination and screening and early detection and treatment of precancerous cervical lesions.

Trends in HPV-associated cancer incidence in Texas medically underserved regions

BACKGROUND

While cervical cancer incidence rates (IR) in the United States have dropped in the last 20 years, non-cervical human papillomavirus (HPV) associated cancers increased. Many people in Texas (TX) live in medically underserved areas and have higher risk of developing HPV-associated cancers. Since previous studies of these regions focused on cervical cancer, we included other HPV-associated cancers in our analysis of IR in East TX and the TX-Mexico Border compared to other TX regions.

METHODS

Cancer data from 2006 to 2019 were obtained from the TX Cancer Registry. Cases of HPV-associated cervical, vaginal, vulvar, penile, anal, and oropharyngeal cancers and corresponding patient-level demographic data were included. We calculated IR per 100,000 and drew heat maps to visualize cancer IR by county. To control potential confounders, we added county-level risk factors: rates for smoking, excessive drinking, obesity, STIs, primary care provider availability and dentist availability, from the County Health Rankings and Roadmaps program. We reported IRs by region and time and estimated unadjusted and adjusted risk ratio (RR) for association of each type of cancer and region. Lastly, we created adjusted models for each cancer by period to see time trends of regional differences.

RESULTS

Risk of anal, cervical, and oropharyngeal cancer was lower at parts of the Border than in the rest of TX in the adjusted model. We also observed increasing anal and oropharyngeal cancer risk and decreasing cervical and vaginal cancer risk over time.

CONCLUSION

Patient sociodemographics, behavioral risk factors, and access to care may contribute to some observed differences in cancer IR across regions. This indicates that targeted prevention efforts towards these regions, especially in low socioeconomic status communities, may benefit future generations.

Culturally Competent Education and Human Papillomavirus Self-Sampling Achieves Healthy People 2030 Cervical Screening Target Among Low-Income Non-Hispanic Black and Hispanic Women

PURPOSE

Disparities in cervical cancer screening, incidence, and mortality exist in the United States. Cervical cancer incidence and mortality rates in Texas are 20% and 32% higher, respectively, than national averages. Within Texas, these rates are significantly higher among non-Hispanic (NH) Black and Hispanic women. Cervical cancer screening uptake is lower among NH Black and Hispanic women (72.9% and 75.9%, respectively) compared with White women (85.5%) in Texas.

METHODS

During March-August 2023, we conducted a pilot study that offered culturally competent education and human papillomavirus (HPV) self-sampling kits to women in two public housing projects in Houston, TX, that have predominantly NH Black or Hispanic residents. Among those eligible for cervical cancer screening, 35% (n = 24) of the NH Black and 34% (n = 16) of the Hispanic women were found to be underscreened per the US Preventive Services Task Force Guideline. We recruited 40 (24 NH Black and 16 Hispanic) eligible women for our study. The study was approved by the MD Anderson institutional review board and registered with ClinicalTrials.gov (NCT04614155-March 11, 2020).

RESULTS

Seventy-five percent of the NH Black and 87% of the Hispanic participants completed the HPV self-sampling procedures per protocol. Samples of 17% NH Black and 12% Hispanic participants showed a performance error. Overall, cervical cancer screening uptake improved from 65% to 91% among NH Black and from 66% to 96% among Hispanic participants.

CONCLUSION

Culturally competent education and HPV self-sampling resulted in remarkable improvement in cervical cancer screening uptake among underscreened NH Black and Hispanic women residents of Houston public housing projects. Implementing this strategy could significantly reduce cervical cancer incidence and mortality among similar populations in the United States and globally.

Current status and challenges in timely detection of cervical cancer in Mexico: expert consensus

Cervical cancer is a significant public health problem in low- and middle-income countries, accounting for 85% of new cases worldwide. Due to poorly organized screening programs, cervical cancer is more likely to develop in vulnerable groups who do not initiate or rarely undergo screening. Cervical cytology and detecting high-risk human papillomavirus types are the recommended screening tools. Further, these strategies allow for accurately identifying women at a higher risk of cervical cancer and establishing screening times. New detection tools, such as novel biomarkers or automatic HPV detection in the vagina or urine, can improve screening coverage. This review aims to identify the challenges faced by detection programs and screening tools in Mexico to provide evidence-based recommendations to improve early detection programs for cervical cancer.

Interventions to increase follow-up of abnormal cervical cancer screening results: A systematic literature review and meta-analysis

INTRODUCTION

Ensuring timely follow-up of abnormal screening results is essential for eliminating cervical cancer.

OBJECTIVE

The purpose of the study was to review single and multicomponent interventions designed to improve follow-up of women with abnormal cervical cancer screening results. We report on effectiveness across studies, and describe what aspects of these interventions might be more impactful.

METHODS

Publications were searched between January 2000 and December 2022. The search included observational, quasi-experimental (pre-post studies) and randomized controlled studies describing at least one intervention to increase follow-up of women with abnormal cervical cancer screening results. Outcomes of studies included completion of any follow-up (i.e., attending a follow-up appointment), timely diagnosis (i.e., colposcopy results within 90 days of screening) and time to diagnostic resolution (i.e., days between screening and final diagnosis). We assessed risk of bias for observational and quasi-experimental studies using the Newcastle-Ottawa Scale (NOS) tool and the Cochrane collaboration tool for randomized studies. We conducted a meta-analysis using studies where data were provided to estimate a summary average effect of the interventions on follow-up of patients and to identify characteristics of studies associated with an increased effectiveness of interventions. We extracted the comparison and intervention proportions of women with follow-up before and after the intervention (control and intervention) and plotted the odds ratios (ORs) of completing follow-up along with the 95% confidence intervals (CIs) using forest plots for the interventions vs. controls when data were available.

FINDINGS

From 7,457 identified studies, 28 met the inclusion criteria. Eleven (39%) of the included studies had used a randomized design. Most studies (63%) assessed completion of any follow-up visit as the primary outcome, whereas others measured time to definite diagnosis (15%) or diagnostic resolution (22%). Navigation was used as a type of intervention in 63% of the included studies. Most interventions utilized behavioral approaches to improve outcomes. The overall estimate of the OR for completion of follow-up for all interventions was 1.81 (1.36-2.42). The highest impact was for programs using more than one approach (multicomponent interventions) to improve outcomes with OR = 3.01 (2.03-4.46), compared with studies with single intervention approaches with OR = 1.56 (1.14-2.14). No statistical risks were noted from publication bias or small-study effects in the studies reviewed.

CONCLUSION

Our findings revealed large heterogeneity in how follow-up of abnormal cervical cancer screening results was defined. Our results suggest that multicomponent interventions were more effective than single component interventions and should be used to improve follow-up after abnormal cervical cancer screening results. Navigation appears to be an important tool for improving follow-up. We also provide recommendations for future studies and implications for policy in terms of better defining outcomes for these interventions.

A Comprehensive Program to Improve Treatment of Precancerous Cervical Lesions in the Rio Grande Valley of Texas

OBJECTIVE

To assess the impact of a multicomponent intervention in women with cervical dysplasia who were treated with loop electrosurgical excision procedure (LEEP), as well as the time between colposcopy and treatment.

DESIGN

Retrospective cohort study.

INTERVENTION

Clinic participation in a multicomponent cervical cancer prevention program that included community outreach, patient in-reach, and navigation, as well as provider capacity building with in-person training and ongoing telementoring through Project ECHO.

MAIN OUTCOME MEASURES

Medical records were reviewed to evaluate women with cervical dysplasia undergoing treatment with LEEP within 90 days of colposcopy, as well as time between colposcopy and treatment. Baseline data from year 1 were compared with each subsequent year of implementation. Additional variables examined included patient's age, history of abnormal screening results, and percentage of families living below poverty line based on county of residence, parity, and clinic site. We performed logistic regression and multiple linear regression analyses to assess the programmatic impact in the outcomes of interest by year of program implementation.

RESULTS

A total of 290 women were included in the study. The proportion of women undergoing treatment within 90 days of colposcopy increased from 76.2% at baseline to 91.3% in year 3 and 92.9% in year 4 of program implementation. The odds of undergoing treatment within 90 days were 5.11 times higher in year 4 of program implementation than at baseline. The mean time between colposcopy and LEEP decreased from 62 days at baseline to 45 days by year 4 of program implementation.

CONCLUSIONS

Implementation of our multicomponent cervical cancer prevention program increased the proportion of women undergoing LEEP within 90 days of colposcopy and decreased the time between colposcopy and LEEP. This program has the potential to support cervical cancer prevention efforts and could be implemented in other low-resource settings.

Addressing cervical cancer disparities in Texas: Expansion of a community-based prevention initiative for medically underserved populations

Although cervical cancer is preventable, significant disparities exist in access to screening and prevention services. In medically underserved areas (MUAs) of Texas, these rates are 55% higher compared to the remainder of the US. In 2019, we expanded a multicomponent, comprehensive program to improve cervical cancer prevention in partnership with 13 clinics and mobile vans in MUAs of Texas. Our multicomponent intervention program consists of community education and patient navigation coupled with a training/mentoring program for local medical providers to perform diagnostic procedures and treatment for patients with abnormal screening results. Hands-on training courses to learn these skills are coupled with biweekly telementoring conferences using Project ECHO® (Extension for Community Healthcare Outcomes). This program was implemented in 2015 and expanded to other MUAs in Texas in 2019. From March 2019 to August 2022, 75,842 individuals were educated about cervical cancer screening and HPV vaccination. A total of 44,781 women underwent screening for cervical cancer, and 2,216 underwent colposcopy and 264 underwent LEEP. High-grade cervical dysplasia was diagnosed in 658 individuals and invasive cervical cancer in 33 individuals. We trained 22 providers to perform colposcopy and/or LEEP. In addition, 78 Project ECHO telementoring sessions were held with an average of 42 attendees per session, with 72 individual patient cases discussed. Our comprehensive community-based prevention initiative for medically underserved populations has led to a significant number of individuals undergoing cervical cancer screening in MUAs, as well as improved access to colposcopy and LEEP services.

Barriers to breast and cervical cancer screening uptake among Black, Asian, and Minority Ethnic women in the United Kingdom: evidence from a mixed-methods systematic review

BACKGROUND

Cancer is currently the leading cause of mortality globally, with new cancer cases estimated at 19.3 million and almost 10 million deaths in 2020. Specifically, breast and cervical cancer incidence and mortality prevalence among women of the minority group or marginalised populations in Europe have continued to be a public health concern due to the low uptake of cancer screening. Thus, this study utilised a mixed-method systematic review to identify barriers to breast and cervical screening uptake among Black, Asian, and Minority Ethnic women in the United Kingdom.

METHODS

Databases including PubMed, CINAHL, British Nursing Index, Web of Science, EMBASE, and Scopus databases, were systematically searched for studies on barriers to breast and cervical screening uptake among Black, Asian, and Minority Ethnic women in the United Kingdom published in English between January 2010 to July 2022. This mixed-method systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines in reporting the included studies' results. The cluster mapping approach was used to identify and classify the barriers into themes.

RESULTS

Thirteen eligible studies were included in this current review. Seven of the thirteen studies used quantitative cross-sectional research design, while six used qualitative cross-sectional research design. These studies were conducted across the United Kingdom. Five themes were developed from the cluster mapping, and thirty-four sub-theme barriers to the uptake of breast and cervical cancer screening among Black, Asian, and Minority Ethnic women in the United Kingdom were identified. The developed themes in relation to the barriers include; socio-demographic characteristics, health service delivery, cultural, religious & language, the gap in knowledge & awareness, and emotional, sexual & family support.

CONCLUSION

The study concluded that barriers in socio-demographic characteristics, health service delivery, cultural, religious and language, the gap in knowledge & awareness, and emotional, sexual & family support were identified as non-uptake of breast and cervical cancer screening among Black, Asian, and Minority Ethnic women in the United Kingdom. Reducing or eliminating these barriers would improve the benefits of timely breast and cervical cancer screening in the United Kingdom.

Ethnic disparities in childhood leukemia survival by border residence: A Texas population-based analysis

BACKGROUND

The US-Mexico border is a medically underserved region where survival disparities have been observed in adults diagnosed and treated for various malignancies. Studies examining survival disparities among children living in this region and diagnosed with cancer are lacking. The objective of this study was to evaluate the impact of border residence on survival among children with acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and living near the Texas-Mexico border at the time of their diagnosis. The authors hypothesized that this group experiences inferior survival compared with patients with childhood leukemia living in nonborder areas.

METHODS

The authors conducted a retrospective survival analysis leveraging data from the Texas Cancer Registry. The study included patients aged birth to 19 years who were diagnosed with ALL or AML between 1995 and 2017. Cox proportional hazards models were used to evaluate the factors associated with the risk of death. Overall survival estimates were calculated using Kaplan-Meier methods.

RESULTS

During the study period, there were 6002 children diagnosed with ALL and 1279 diagnosed with AML. Inferior 5-year overall survival was observed among children with ALL living along the border region compared with those living in nonborder areas (77.5% vs. 85.8%). In adjusted models, children with ALL living along the border experienced a 30% increased hazard of death versus children living in nonborder areas. In contrast, for children with AML, survival estimates did not vary by border versus nonborder residence.

CONCLUSIONS

Living along the border was associated with inferior survival among children with ALL, but not among children with AML. Additional studies are urgently needed to identify the factors driving these disparities to effectively design multilevel interventions and influence state and national cancer control programs.

Navigating Financial Barriers to Papanicolaou Tests and Mammograms for Young Adult Women Residing in Rural and Border Areas of Texas

Purpose: Costs of Papanicolaou (Pap) tests and mammograms are a primary barrier for women aged 18-39 seeking screening and diagnostic services. Race/ethnicity and rural/border resident status compound their risks for delayed diagnosis, possibly resulting in higher mortality. Methods: We analyzed cross-sectional data from young adult (YA) women (aged 18-39) from a cancer education and patient navigation (PN) program in rural and border Texas from 2012 to 2016. Descriptive statistics, Chi-square tests, and logistic regressions summarized sociodemographic variables and receipt of PN, Pap tests, and mammograms. Results: The sample consisted of 1181 women aged 31.8 years (standard deviation 5.5) on average. A total of 795 (67.3%) received PN, 494 (41.8%) received a Pap test, and 121 (10.3%) received a mammogram. The YA women attending the program due to cost (odds ratio [OR]: 7.24; confidence interval [CI]: 4.74-11.05) and reporting 1 (OR: 3.84; CI: 2.40-6.14) or 2+ barriers (OR: 6.00; CI: 3.61-9.99) had higher odds of being navigated than those not concerned about cost and not identifying a barrier. The YA women attending due to cost (OR: 2.22, CI: 1.61-3.05) and receiving navigation (OR: 1.92; CI: 1.29-2.84) had higher odds of receiving a Pap test than their counterparts. The majority receiving a mammogram were worried about cost (85.1%); 40.5% had a family history of breast cancer, and a doctor or nurse recommended a mammogram for 15.7%. Conclusion: Detection of cervical and breast cancer in YA women residing in rural and border Texas may be improved with PN to assist with financial barriers to care and service coordination.

Addressing high cervical cancer rates in the Rio Grande Valley along the Texas-Mexico border: a community-based initiative focused on education, patient navigation, and medical provider training/telementoring

AIMS

Cervical cancer incidence and mortality rates are approximately 55% higher in the Rio Grande Valley (RGV) along the Texas-Mexico border compared with the average rates in the US. Our aim was to improve cervical cancer prevention efforts in the RGV through a comprehensive multilevel intervention initiative focused on community education, patient navigation, and training of local providers.

METHODS

We initiated a program in the RGV which consisted of (1) community education, (2) patient navigation, and (3) a training/mentoring program for local medical providers including hands-on training courses coupled with telementoring using Project ECHO® (Extension for Community Health Outcomes). We assessed the number of women undergoing cervical cancer screening, diagnosis, and treatment at three participating clinics caring for underserved women in the region.

RESULTS

From November 2014 to October 2018, 14,846 women underwent cervical cancer screening. A total of 2030 (13.7%) women underwent colposcopy for abnormal results (179% increase over baseline) and 453 women underwent loop electrosurgical excision procedures (LEEPs) for treatment of cervical dysplasia. Invasive cancer was diagnosed in 39 women who were navigated to a gynecologic oncologist for treatment. Seven local medical providers were trained to perform colposcopy and/or LEEP. Project ECHO telementoring videoconferences were held every 2 weeks for a total 101 sessions with an average of 22 participants per session and a total of 180 patient cases presented and discussed.

CONCLUSIONS

Our program led to a large number of women undergoing diagnosis and treatment of cervical dysplasia in the RGV. If sustained, we anticipate these efforts will decrease cervical cancer rates in the region. The program is currently being expanded to additional underserved areas of Texas and globally to low- and middle-income countries.

The continuing evolution of a cancer prevention, screening, and survivorship ECHO : A second year of implementation

INTRODUCTION

An estimated 39,010 Indiana residents were diagnosed with cancer in 2021. To address the cancer burden, Project ECHO (Extension Community Healthcare Outcomes) was launched in 2019 in Indiana to build specialty healthcare capacity among non-specialists. Due to positive outcomes from the pilot year, the Cancer Prevention, Screening, and Survivorship ECHO was implemented for a second year. The purpose of this study was to measure the participation and regional impact of this ECHO.

METHODS

ECHO sessions occurred twice monthly from October 2020 to October 2021. Changes were implemented in response to feedback from the pilot year, including making the curriculum more practical for learners and adding accreditation opportunities. Participant information and feedback was extracted from electronic surveys for review.

RESULTS

There were 24 ECHO sessions with 213 unique participants, increased from 140 unique participants in the pilot year. An average of 23.5 individuals attended each session, increased from 15.5 individuals per session. Enrolled participants served in a diverse set of roles and represented 247 zip codes, 30 Indiana counties, and 32 states across the United States, each of which increased from the pilot year.

DISCUSSION

In this second year, this ECHO expanded to reach more participants with increased attendance and a more diverse distribution of roles within healthcare, which may be attributed to feedback-driven curriculum design. Cancer care is multi-disciplinary, with health educators, nurses, and administrators, each acting within the cancer care continuum. As a result, this ECHO has been adapted to serve an increasingly broad distribution of professionals.

CONCLUSION

The second year of the Cancer Prevention, Screening, and Survivorship ECHO displayed increased overall enrollment and participation, greater diversity among participant roles, and a wider reach across Indiana and the United States.

County-Level Poverty and Barriers to Breast and Cervical Cancer Screening in a Health Education and Patient Navigation Program for Rural and Border Texas Residents

The study examined the impact of (1) county-level poverty rates and (2) patient navigation on breast and cervical cancer screening outcomes for women in rural and border counties in Texas reporting barriers to screening.Univariate analyses described the distribution and screening prevalence rates in the sample, while a series of random intercept logistic regression models analyzed mammogram (N = 2326 women aged 40+) and Papanicolaou (Pap; N = 2959 women aged 21-64) screening separately.Mammogram and Pap screening prevalence rates were highest among women who were aged 40-64, Spanish-speaking Latinas, lower educated, attending cancer education events because of the cost of the screenings, patient navigation recipients, living in the south region of Texas, and in counties with high poverty. Although models indicated significant variability in screening rates by county, county-level poverty was only significantly associated with odds of getting Pap screening in adjusted models. Not receiving patient navigation vs. receiving it was associated with lower odds for both mammogram (OR: 0.51, CI: 0.38-0.70) and Pap (OR: 0.69, CI: 0.50-0.94) screenings.County-level variation in screening rates exists for both mammogram and Pap tests and should be considered in the development and implementation of screening interventions in rural and border areas. However, other factors beyond poverty levels may explain the variation.

Perceived Barriers and Facilitators in Accessing Cervical Cancer Screening: The Voices of Women in a Low-Income Urban Community

Although advancements in cervical cancer prevention have helped reduce the incidence, mortality, and prevalence, access to these preventive services has not been experienced equally by all women in the United States. The purpose of this study was to learn about the factors that affect access to preventive services in a low-income, primarily Black community. Using a community-based participatory research approach, women were recruited to participate in 7 focus groups, with 6 to 8 women per group (N = 45). Participants were mainly Black (64%), with a mean age of 46 years, and 60% reporting completing at least some college. The discussions were transcribed, and text data were organized using Dedoose software. Guided by qualitative content analysis, the data were analyzed through an iterative process of coding and condensing the codes into themes. Ten types of barriers and 11 facilitators relating to cervical cancer screening access were identified and grouped into 7 themes. Participants provided suggestions for promoting cervical cancer screening in their community. On the basis of the findings of the data, the researchers conceptualized and mapped culturally and geographically appropriate interventions to promote cervical cancer screening within the community of interest.

Cancer prevention, screening, and survivorship ECHO: A pilot experience with an educational telehealth program

Introduction

The American Cancer Society, Inc. (ACS) estimates that 37,940 Indiana residents were diagnosed with cancer in 2020, which remains the leading cause of death in the state. Across the cancer continuum, national goals have been established targeting recommended benchmarks for states in prevention, screening, treatment, and survivorship. Indiana consistently falls below most goals for each of these targeted categories.

Methods

To address these disparities, we implemented Project ECHO (Extension for Community Healthcare Outcomes) as a virtual telehealth educational platform targeted at local healthcare providers. ECHO programs utilize a novel tele‐mentoring approach to the education of clinicians in a hub/spoke design. Sessions occurred twice monthly from September 2019 to September 2020 and consisted of a traditional didactic lecture and a case‐based discussion led by participating providers.

Results

During the pilot year there were a total of 22 ECHO sessions with 140 different participants. On average, 15.5 spokes attended each session with increasing participation at the end of the year. Post‐session surveys suggested generally favorable perception with 72% of respondents finding the quality “excellent.”

Discussion

Given the increasing rate of recurrent participation toward the end of the pilot year in conjunction with the favorable survey responses following each session, it was felt that the program was overall successful and warranted continued implementation.

Conclusion

The Project ECHO platform is a validated telehealth education platform that has the potential to impact cancer care at multiple points along the cancer continuum at the regional level.

Exploring Health Literacy and the Correlates of Pap Testing Among African Immigrant Women: Findings from the AfroPap Study

African immigrant (AI) women have low rates of Pap testing. Health literacy plays a pivotal role in health behaviors. Sources and types of health information could shape health literacy and inform the Pap testing behaviors of AI women. However, the influences of health literacy, sources, and types of health information along with cultural and psychosocial correlates on the Pap testing behaviors of AI women are poorly understood. To examine how sources and types of health information impact health literacy, and in turn, how health literacy and cultural and psychosocial factors influence the Pap testing behaviors of AI women. An adapted Health Literacy Skills Framework guided the selection of variables for this cross-sectional study. Convenience sampling was used to recruit 167 AI women, 21-65 years. Multivariate logistic regression was used to assess correlates of Pap testing after adjusting for covariates (age, education, English proficiency, employment, income, health insurance, access to primary care, marital status, and healthcare provider recommendation). Most participants (71%) had received a Pap test in the past and used multiple (two or more) sources (65%) and types (57%) of health information. Using multiple sources of health information (aOR 0.11, p < 0.01) but not types of health information was associated with Pap testing. Having negative cultural beliefs (aOR 0.17, p = 0.01) and having high self-efficacy (aOR 9.38, p < 0.01) were significantly associated with Pap testing after adjusting for covariates. High health literacy (OR 3.23, p < 0.05) and high decisional balance (OR 5.28, p < 0.001) were associated with Pap testing in bivariate models but did not remain significant after controlling for covariates. Cultural beliefs was a significant correlate of AI women's Pap testing behaviors regardless of other known social determinants of health (education, English proficiency, age, access to primary care). Disseminating health information through various sources has the potential to promote Pap testing among AI women. Larger studies which utilize a robust sampling strategy and include a diverse group of AI women are needed in order to optimize health interventions aimed at improving Pap test screening behaviors among AI women.

The Role of Sources and Types of Health Information in Shaping Health Literacy in Cervical Cancer Screening Among African Immigrant Women: A Mixed-Methods Study

BACKGROUND

Health literacy is a strong determinant of health outcomes among immigrants. How sources and types of health information influence health literacy in the context of cervical cancer screening among African immigrant women remains unknown.

OBJECTIVE

This study was undertaken to explore how various sources and types of health information influence information sharing and health literacy in the context of cervical cancer screening among African immigrant women.

METHODS

Using a mixed-methods approach, a convenience sample of African immigrant women (N = 167) completed study surveys followed by semi-structured individual phone interviews with a purposive sub-sample (n = 20) of survey participants. The relationship between sources and types of health information and health literacy was assessed using multivariate logistic regression. Emergent themes were identified in the qualitative interviews using content analysis. Qualitative and quantitative data were merged to describe differences and similarities in African immigrant women's experiences and display of health literacy by different sources and types of health information.

KEY RESULTS

Health care providers (78%), women friends (46%), and internet (45%) were the most common sources of health information used by African immigrant women, followed by women relatives (32%), television (22%), social media (17%), and church (16%). Content analysis revealed that the health care provider was rated as the most credible source; personal experiences of family and friends made health information more relatable; and church was the least endorsed source. Health information presented verbally (adjusted odds ratio of 5.51, p = .01) was associated with higher health literacy even after controlling for covariates. Most African immigrant women had health information presented in verbal form (80%), with pictures (43%) being the least popular type of health information.

CONCLUSIONS

Study findings suggest that verbal communication is associated with health literacy in the context of cervical cancer screening among African immigrant women. Health interventions that use peer educators (women friends and family) and incorporate verbal communication may be a more effective strategy in promoting positive cervical cancer health behaviors among African immigrant women. [HLRP: Health Literacy Research and Practice. 2021;5(2):e96-e108.] Plain Language Summary: For this mixed-methods study, a convenience sample of African immigrant women (N = 167) completed study surveys followed by semi-structured individual phone interviews with a purposive sub-sample (n = 20) of the survey participants. Study findings show a strong association between verbal communication and health literacy in the context of cervical cancer screening among African immigrant women.

Perceived Financial Barriers to Cervical Cancer Screening and Associated Cost Burden Among Low-Income, Under-Screened Women

Background: Despite screening's effectiveness in reducing cervical cancer incidence and mortality, disparities in cervical cancer screening uptake remain, with lower rates documented among uninsured and low-income individuals. We examined perceived financial barriers to, and the perceived cost burden of, cervical cancer screening. Materials and Methods: We surveyed 702 low-income, uninsured or publicly insured women ages 25-64 years in North Carolina, U.S., who were not up to date on cervical cancer screening according to national guidelines. Participants were asked about perceived financial barriers to screening and how much they perceived screening would cost. We used multivariable logistic regression to assess the sociodemographic predictors of perceived financial barriers. Results: Seventy-two percent of participants perceived financial barriers to screening. Screening appointment costs (71%) and follow-up/future treatment costs (44%) were most commonly reported, followed by lost pay due to time missed from work (6%) and transportation costs (5%). In multivariable analysis, being uninsured (vs. publicly insured), younger (25-34 vs. 50-64 years), White (vs. Black), and not reporting income data were associated with perceiving screening costs and future treatment costs as barriers to screening. Participants reported wide-ranging estimates of the perceived out-of-pocket cost of screening ($0-$1300), with a median expected cost of $245. Conclusions: The majority of our sample of low-income women perceived substantial financial barriers to screening, particularly related to screening appointment costs and potential follow-up/future treatment costs. Providing greater cost transparency and access to financial assistance may reduce perceived financial barriers to screening, potentially increasing screening uptake among this underserved population. Clinicaltrials.gov registration number NCT02651883.

Cervical cancer screening in the United States: Challenges and potential solutions for underscreened groups

Cervical cancer screening rates in the United States are generally high, yet certain groups demonstrate disparities in screening and surveillance. Individuals at greatest risk for cervical cancer are often from marginalized or underserved groups who do not participate in regular screening for a variety of reasons. Using the Population-based Research to Optimize the Screening Process (PROSPR) Trans-Organ Conceptual Model, including concepts of individual-, provider-, facility-, system-, or policy-level factors, we provide a commentary to highlight reasons for low screening participation among subgroups in the U.S. These include racial and ethnic minorities, rural residents, sexual and gender minorities, those with limited English proficiency, those with particular religious beliefs, and various health conditions. We describe barriers and offer potential solutions for each group. In addition, we discuss cross-cutting barriers to screening including difficulty interacting with the healthcare system (limited knowledge and health literacy, lack of provider recommendation/contact), financial (cost, lack of insurance), and logistical barriers (e.g., lack of usual source of care, competing demands, scheduling issues). Solutions to address these barriers are needed to improve screening rates across all underscreened groups. Changes at state and national policy levels are needed to address health insurance coverage. Mobile screening, ensuring that interpreters are available for all visits, and targeted in reach at non-gynecological visits can further overcome barriers. Employing community outreach workers can increase community demand for screening, and patient navigators can improve adherence to both screening and follow-up diagnostic evaluation. HPV self-sampling can address multiple barriers to cervical cancer screening.

The Use of Health-Related Technology to Reduce the Gap Between Developed and Undeveloped Regions Around the Globe

Cancer is the second leading cause of death worldwide, with approximately 70% of the 9.6 million deaths per year occurring in low- and middle-income countries (LMICs), where there is critical shortage of human and material resources or infrastructure to deal with cancer. If the current trend continues, the burden of cancer is expected to increase to 22 million new cases annually by 2030, with 81% of new cases and almost 88% of mortality occurring in LMICs. Global health places a priority on improving health and reducing these disparities to achieve equity in health for all people worldwide. In today's hyper-connected world, information and communication technologies (ICTs) will increasingly play an integral role in global health. Here, we focus on how the use of health-related technology, specifically ICTs and artificial intelligence (AI), can help in closing the gap between high-income countries (HICs) and LMICs in cancer care, research, and education. Key examples are highlighted on the use of telemedicine and tumor boards, as well as other online resources that can be leveraged to advance global health.

Co-infection with trichomonas vaginalis increases the risk of cervical intraepithelial neoplasia grade 2-3 among HPV16 positive female: a large population-based study

Background

Evidence suggested that vaginal microbiome played a functional role in the progression of cervical lesions in female infected by HPV. This study aimed at evaluating the influence of common vaginal infection on the carcinogenicity of high risk HPV (hr-HPV).

Methods

From January 15, 2017 to December 31, 2017, 310,545 female aged at least 30 years old had been recruited for cervical cancer screening from 9 clinical research centers in Central China. All the recruited participants received hr-HPV genotyping for cervical cancer screening and vaginal microenvironment test by a high vaginal swab. Colposcopy-directed biopsy was recommended for female who were infected with HPV 16 and HPV 18, and other positive hr-HPV types through test had undertaken triage using liquid-based cytology, cases with the results ≥ ASCUS among them were referred to colposcopy directly, and cervical tissues were taken for pathology examination to make clear the presence or absence of other cervical lesions.

Results

Among 310,545 female, 6067 (1.95%) were tested with positive HPV 16 and HPV 18, 18,297 (5.89%) were tested with other positive hr-HPV genotypes, cervical intraepithelial neoplasia (CIN) 1, CIN 2, CIN 3 and invasive cervical cancer (ICC) were detected in 861 cases, 377 cases, 423 cases, and 77 cases, respectively. Candida albicans and Gardnerella were not associated with the detection of cervical lesions. Positive trichomonas vaginitis (TV) was correlated with hr-HPV infection (p < 0.0001). Co-infection with TV increased the risk of CIN 1 among female infected with hr-HPV (OR 1.18, 95% CI: 1.42–2.31). Co-infection with TV increased the risk of CIN 2–3 among female infected with HPV 16 (OR 1.71, 95% CI: 1.16–2.53).

Conclusions

Co-infection of TV and HPV 16 is a significant factor for the detection of cervical lesions.

LncRNA EWSAT1 upregulates CPEB4 via miR-330-5p to promote cervical cancer development

Long non-coding RNA (lncRNA) Ewing sarcoma associated transcript 1 (EWSAT1) is an oncogene in a variety of tumors. Here, we planned to demonstrate EWSAT1 function in cervical cancer and further illustrate its underlying mechanism. EWSAT1 expression in cervical cancer was evaluated through qRT-PCR. Colony forming capacity was measured by colony formation assay and cell proliferation ability was measured by CCK-8 kit. Wound healing experiment was applied to test the cell migration and transwell assay was applied to test the invasion ability. Luciferase assay was employed to demonstrate EWSAT1 and miR-330-5p interaction. In cervical cancer, the expression of EWSAT1 was enhanced and contributed to the poor prognosis. Downregulated EWSAT1 expression inhibited Hela cell migration, proliferation, and invasion. EWSAT1 targeted to miR-330-5p and upregulated cytoplasmic polyadenylation element-binding protein 4 (CPEB4) expression by sponging miR-330-5p. Our study revealed that EWSAT1 enhances CPEB4 expression through sponging miR-330-5p, thereby promoting cervical cancer development, which might provide potential therapeutic targets for clinically cervical cancer patients.

LncRNA SNHG7 Functions as an Oncogene in Cervical Cancer by Sponging miR-485-5p to Modulate JUND Expression

BACKGROUND

Long non-coding RNA (LncRNA) SNHG7 is involved in the development of multiple cancers. However, its role in cervical cancer (CC) has not been elucidated. This study aimed to explore the function of SNHG7 in CC progression and the underlying mechanisms.

MATERIALS AND METHODS

The expression levels of SNHG7 and miR-485-5p in CC tissues and cell lines were measured by qPCR. Functional experiments including CCK-8 assay, wound healing assay, transwell assay, flow cytometry, Western blot, luciferases reporter assay and immunoprecipitation (RIP) were performed to explore the SNHG7/miR-485-5p/JUND pathway. Additionally, in vivo study was carried out by establishing tumor xenograft models.

RESULTS

We found that SNHG7 was markedly enhanced in CC tissues and cell lines, and associated with poor clinical characteristics. In vitro, knockdown of SNHG7 inhibited CC cell proliferation, migration and invasion, as well as aggravated cell apoptosis. As to mechanism investigation, rescue experiments revealed that miR-485-5p inhibitor could partially reverse the effects on CC cells induced by SNHG7 knockdown. SNHG7 upregulated JUND expression via miR-485-5p. Moreover, tumor xenograft models were established to confirm the findings in vivo.

CONCLUSION

SNHG7 promoted CC progression through miR-485-5p/JUND axis. The SNHG7/miR-485-5p/JUND pathway might provide a novel therapeutic target for CC treatment.

In vivo imaging of cervical precancer using a low-cost and easy-to-use confocal microendoscope

Cervical cancer incidence and mortality rates remain high in medically underserved areas. In this study, we present a low-cost (<$5,000), portable and user-friendly confocal microendoscope, and we report on its clinical use to image precancerous lesions in the cervix. The confocal microendoscope employs digital apertures on a digital light projector and a CMOS sensor to implement line-scanning confocal imaging. Leveraging its versatile programmability, we describe an automated aperture alignment algorithm to ensure clinical ease-of-use and to facilitate technology dissemination in low-resource settings. Imaging performance is then evaluated in ex vivo and in vivo pilot studies; results demonstrate that the confocal microendoscope can enhance visualization of nuclear morphology, contributing to significantly improved recognition of clinically important features for detection of cervical precancer.

Recruiting African Immigrant Women for Community-Based Cancer Prevention Studies: Lessons Learned from the AfroPap Study

Recruitment in research can be challenging, particularly for racial/ethnic minorities and immigrants. There remains a dearth of research identifying the health and sociocultural needs of these populations related to recruitment. To describe our experiences and lessons learned in recruiting African immigrant (AI) women for the AfroPap study, a community-based study examining correlates of cervical cancer screening behaviors. We developed several recruitment strategies in collaboration with key informants and considered published recruitment methods proven effective in immigrant populations. We also evaluated the various recruitment strategies using recruitment records and study team meeting logs. We enrolled 167 AI women in the AfroPap study. We used the following recruitment strategies: (1) mobilizing African churches; (2) utilizing word of mouth through family and friends; (3) maximizing research team's cultural competence and gender concordance; (4) promoting altruism through health education; (5) ensuring confidentiality through the consenting and data collection processes; and (6) providing options for data collection. Online recruitment via WhatsApp was an effective recruitment strategy because it built on existing information sharing norms within the community. Fear of confidentiality breaches and time constraints were the most common barriers to recruitment. We were successful in recruiting a "hard-to-reach" immigrant population in a study to understand the correlates of cervical cancer screening behaviors among AI women by using a variety of recruitment strategies. For future research involving African immigrants, using the internet and social media to recruit participants is a promising strategy to consider.

Advances in technologies for cervical cancer detection in low-resource settings

Introduction: Cervical cancer mortality rates remain high in low- and middle-income countries (LMICs) and other medically underserved areas due to challenges with implementation and sustainability of routine screening, accurate diagnosis, and early treatment of preinvasive lesions. Areas covered: In this review, we first discuss the standard of care for cervical cancer screening and diagnosis in high- and low-resource settings, biomarkers that correlate to cervical precancer and cancer, and needs for new tests. We review technologies for screening and diagnosis with a focus on tests that are already in use in LMICs or have the potential to be adapted for use in LMICs. Finally, we provide perspectives on the next five years of technology development for improved cervical cancer screening and diagnosis in LMICs. Expert opinion: Innovation toward improved molecular and imaging tests is needed to enable effective, affordable see-and-treat approaches to detect and treat cervical precancer in a single visit. Current molecular tests remain too complex and/or costly for widespread use. Especially with imaging tests, decision support may improve performance of new technologies.
