Understanding Breast Cancer Awareness, Perceptions, and Screening Practices Among the Population of Jazan, Saudi Arabia: A Cross-Sectional Study

Incidence and survival of primary metastatic breast cancer in Denmark; implication of breast cancer screening, classification, and staging practice.

Primary metastatic breast cancer (pMBC) accounts for 5-10% of annual breast cancers with a median survival of 3-4 years, varying among subtypes. In Denmark, the incidence of breast cancer increased until 2010, followed by a stabilisation. Several factors influencing pMBC incidence and survival, including screening prevalence, staging methods, and classification standards, remain pivotal but inadequately documented. This retrospective observational study involving pMBC patients diagnosed between 2000 and 2020 encompassed all Danish oncology departments. Data from the Danish Breast Cancer Group database and the National Patient Register included diagnosis specifics, demographics, treatment, and follow-up. Between 2000 and 2020, 3,272 patients were diagnosed with pMBC, a rise from 355 patients in 2000-2004 to 1,323 patients in 2015-2020. The increase was particularly observed in patients aged 70 years or older. Changes in tumour subtypes were observed, notably with a rise in human epidermal growth factor receptor 2 (HER2)-positive cases but a steady distribution of estrogen receptor (ER) status. Diagnostic practices changed over the two decades, with 6% evaluated with PET/CT (positron emission tomography-computed tomography) or CT (computed tomography) with a bone evaluation in 2000-2004 and 65% in 2015-2020. Overall survival (OS) improved from 23 months in 2000-2004 to 33 months in 2015-2020. In patients with ER-positive and HER2-positive disease, the multivariable model showed improved survival by year of diagnosis, and further, patients with ER-negative/HER2-negative disease fared worse the first 2 years after diagnosis. Our study delineates changes in the treatment and survival of pMBC over two decades. Stage migration, screening introduction, and changes in registration practice, however, prevent a valid assessment of a possible causal relationship.

Abstract PO2-28-09: Long-term Breast Cancer Risk Prediction in Black Women: External Validation of a Mammography-driven AI Model

Abstract Despite the demonstrated potential of artificial intelligence (AI) in breast cancer risk assessment for personalizing screening recommendations, further validation is required regarding AI model bias and generalizability. We performed external validation in Black women of a mammography-driven AI breast cancer risk model (Mirai) originally developed on screening cohorts primarily consisting of White women. In this institutional review board-approved, Health Insurance Portability and Protection Act (HIPAA)-compliant study under a waiver of consent, we retrospectively analyzed a case–cohort sample nested within the core academic breast cancer screening practice of BJC Healthcare, the hospital partner of Washington University in St. Louis. For the purposes of this validation study, relying on 2D digital mammography (DM) images, we focused on Black women presenting for annual DM screening (Selenia or Selenia Dimensions; Hologic) between 2008 and 2018. Eligible breast cancer cases were derived from all women with a breast cancer diagnosis (with associated biopsy-confirmed tumor pathology via institutional cancer registry) after negative (BI-RADS 1 or 2) DM screening 1 to 5 years prior to cancer diagnosis. We also identified a random sample of controls, defined as women who had negative (BI-RADS 1 or 2) DM screening, with 1 to 5 years of screening follow-up without a cancer diagnosis. Risk scores for all DM exams were calculated via the Mirai model. Performance was evaluated using concordance-index (C) analyses and associated 95% confidence intervals (CIs) for the entire cohort, as well as for study subgroups of invasive versus in-situ cancer and cancer molecular subtypes. We analyzed 1368 DM screening exams, including 672 DM exams from 391 women diagnosed with breast cancer (mean age, 58 years; standard deviation, 10 years) and 696 DM exams from 406 controls (mean age, 55 years; standard deviation, 10 years). The overall C-index was 0.62 [95% CIs 0.60–0.64] for all Black women, which was lower compared to previously reported validation results for Mirai in studies of similar design on predominantly White and racially diverse screening cohorts (C-index = 0.67-0.78). There was no evidence of a significant difference between invasive and in-situ cancer (C-index = 0.64 [95% CIs 0.61–0.66] vs. 0.64 [95% CIs 0.61–0.67]). Compared to other cancer molecular subtypes, performance was significantly higher among triple-negative (C-index = 0.67 [95% CIs 0.62–0.71]) and estrogen receptor (ER) negative cancer (C-index = 0.66 [95% CIs 0.61–0.70]). A previously developed mammography-driven AI model showed overall good performance in long-term breast cancer risk assessment in a dataset of Black women only, particularly for triple-negative and ER- cancer types. However, performance was lower compared to previously reported validation results from similar studies on predominantly White and racially diverse screening cohorts. Our results suggest that further refinements are needed towards more accurate breast cancer risk assessment in Black women.

Factors influencing breast cancer screening practices among women worldwide: a systematic review of observational and qualitative studies

BackgroundThe variation in breast cancer incidence rates across different regions may reflect disparities in breast cancer screening (BCS) practices. Understanding the factors associated with these screening behaviors is crucial for identifying modifiable elements amenable to intervention. This systematic review aims to identify common factors influencing BCS behaviors among women globally.MethodsRelevant papers were sourced from PubMed, Scopus, Embase, and Google Scholar. The included studies were published in English in peer-reviewed journals from January 2000 to March 2023 and investigated factors associated with BCS behaviors.ResultsFrom an initial pool of 625 articles, 34 studies (comprising 29 observational and 5 qualitative studies) with 36,043 participants were included. Factors influencing BCS behaviors were categorized into nine groups: socio-demographic factors, health status history, knowledge, perceptions, cultural factors, cues to action, motivation, self-efficacy, and social support. The quality appraisal scores of the studies ranged from average to high.ConclusionsThis systematic review highlights factors pivotal for policy-making at various levels of breast cancer prevention and assists health promotion professionals in designing more effective interventions to enhance BCS practices among women.

Abstract CT272: A cluster randomized trial to evaluate a church-based navigation model to increase breast cancer screening in Korean women (Faith In Action!): Trial in progress

Abstract Background: Breast cancer is the most commonly diagnosed cancer among Korean American women and incidence in this group is rising. Advanced-stage disease is more frequent among Korean women diagnosed with breast cancer than in other ethnicities due to low adherence to screening. Lower socioeconomic status, cultural barriers, perceived norm, distrust of healthcare system, and lack of awareness and culturally tailored communication on benefits of screening contribute to low screening utilization. Church settings offer important platforms for education as a majority of Korean American women >50 years regularly attend church services. Thus, the objective of this trial was to evaluate the efficacy of a culturally tailored intervention “Faith in Action!” on breast cancer screening adherence rates among Korean American women. Methods: A parallel cluster randomized trial with staggered roll-out will be conducted to evaluate the efficacy of the “Faith in Action!” intervention, a church-based small group education and lay health navigator program, delivered by trained church members, on breast cancer screening among Korean American women (NCT05298605). This study was designed and conducted in partnership with a Community Advisory Board. Trial enrollment began in July 2022 and is ongoing. Twenty-four total Korean churches in Los Angeles were randomized within blocks of 8 churches to either intervention or waitlist control conditions in a 1:1 ratio. Using a train-the-trainer approach, lay navigators from the Korean Church community nominated by church leadership are trained and certified to deliver the Faith in Action! intervention to study participants over a 6-month program period. Participants at churches randomized to the waitlist control group receive an educational presentation on physical activity and nutrition and, after 6-month follow-up, are invited to receive the Faith in Action! intervention. Eligible participants include women of Korean descent, ages 45-75 years, who: attend a participating church, do not have a breast cancer diagnosis, and did not receive mammogram in the last 2 years. The primary outcome is adherence to breast cancer screening guidelines within 6 months from end of program. Secondary outcomes include adherence to breast cancer screening within 1 year and participant knowledge about breast cancer screening practices. Qualitative interviews will be conducted to assess participants’ knowledge and barriers surrounding cancer screening decisions and program acceptability. To date, 16 churches (149 total participants) have been enrolled in the study and are being followed. It is expected that findings from this research will inform community-based efforts to increase breast cancer screening adherence among Korean American women and improve understanding of screening barriers in this group that is disproportionately impacted by breast cancer, while building capacity and opportunities for sustainability in the Korean faith community.

Lacked of Breast Cancer Awareness of Indonesian Rural Women: A Descriptive Study to Adult Women in District Pangandaran, Indonesia

Breast cancer remains a significant global health challenge, particularly in low and middle-income countries like Indonesia. Patients with advanced metastatic breast cancer have a dismal prognosis. A cancer promotion program’s failure can be attributed to low awareness of breast cancer. This descriptive study aimed to evaluate breast cancer awareness among adult women in District Pangandaran, Indonesia. Data was gathered in July 2018 from 189 individuals using a verified Breast Cancer Awareness Measure instrument developed by Cancer Research UK. Results revealed a concerning lack of awareness among participants regarding various breast cancer risk factors, symptoms, and screening practices. Additionally, reluctance to seek medical help due to fear of diagnosis was observed, particularly among housewives without health insurance. These findings highlight the urgent need for comprehensive health programs to enhance breast cancer awareness and promote early detection strategies tailored to the Indonesian population, especially in rural areas. Healthcare providers and public health workers play a vital role in this effort, along with implementing innovative health promotion policies by the government to improve cancer prevention programs.

Study of North Jordanian women's knowledge of breast cancer causes and medical imaging screening advantages

Backgroundamong both industrialized and developing nations, breast cancer is the most prevalent type of cancer among women. The purpose of this research project is to evaluate adult females in northern Jordan's level of awareness regarding breast cancer risk factors and potential causes. A link between certain variables and their comprehension of breast cancer risk factors was established, enabling us to take appropriate measures to increase women's awareness. MethodsWe conducted a cross-sectional study using a self-administered questionnaire to assess the awareness of breast cancer risk factors, treatment beliefs, and screening practices among adult females in north Jordan. There was a scoring system used. IBM SPSS Statistics (Version 20.0) was used to conduct all statistical analyses. ResultsOnly 18.11% of participants (n = 201) reported having little understanding of breast cancer risk factors; 36.31% of participants (n = 403) reported having fair knowledge; and 45.58% of participants (n = 506) reported having a good grasp of breast cancer risk factors. ConclusionThe study's findings show that North Jordanian women are well informed about breast cancer and its potential causes. To improve females' knowledge of breast cancer, however, we advocate for the need for ongoing medical education programs.

Breast cancer quality of care in Syria: screening, diagnosis, and staging

BackgroundThe Syrian decade-long war has severely affected the healthcare system, including almost vanishing cancer screening practices, war-destroyed medical facilities, and lack of continuous medical education. This study aims to present data on the affected breast cancer screening practices, methods of diagnosis, and stages distribution in Syria.MethodsMedical charts of breast cancer patients treated at Albairouni University Hospital between January 2019 and May 2022 were retrospectively reviewed. Eligible patients were women diagnosed with primary breast cancer. Exclusion criteria included females receiving neoadjuvant chemotherapy and incomplete charts. Data regarding the patient’s age, city of residence, marital status, number of children, smoking habits, method of diagnosis, tumor size (T), lymph nodes (N), and distal metastasis (M) were collected. We used Microsoft Excel and Statistical Package for the Social Sciences (SPSS) to analyze data. Descriptive methodology (frequency [n], percentage) was used.ResultsThe number of charts reviewed was 4,500. The number of remaining charts after applying the exclusion criteria was 2,367. The mean age was 51.8 (SD = 11.3). More than half of the patients (58.3%) came from outside Damascus -where the hospital is located- and its suburbs. Less than 5% of the population detected cancer by screening mammography. Only 32.4% of patients were diagnosed by a biopsy, while surgical procedures (lumpectomy and mastectomy) were used to diagnose 64.8% of the population. At the time of diagnosis, only 8% of patients presented with local-stage disease (stages 0 & I), 73% had a regional disease (stages II & III), and 19% had metastatic breast cancer (stage IV).ConclusionOur retrospective chart review analysis is the first comprehensive review in Syria for female breast cancer patients. We found a significant low percentage of patients diagnosed based on a screening mammogram, much higher surgical biopsies rather than a simple imaging-guided biopsy, and much lower than the national average of early-stage disease. Our alarming findings can serve as the base for future strategies to raise the population’s health awareness, create more serious national screening campaigns, and adopt a multidisciplinary approach to the disease in Syria.

Breast Cancer Screening: Knowledge, Attitudes, and Practices among Female University Students in The Gambia

Background. Breast cancer is the second most prevalent form of cancer in The Gambia, with an incidence rate of approximately 15% and a mortality rate exceeding 50% in 2020. The all-age prevalence stands at 11.25 per 100,000 population. In light of this, we conducted a study to assess the knowledge, attitude, and practice of breast cancer screening among female university students. Method. We conducted an institutional cross-sectional study involving 361 randomly sampled female university students. Data collection was done using a pretested, self-administered questionnaire. We utilized descriptive statistics to describe the prevalence and burden of breast cancer screening among the participants. Results. Our study revealed good knowledge regarding breast cancer screening among female university students, yet 82.8% had a negative attitude about the disease. More than three-quarters (76.6%) of the respondents had never practiced any form of breast cancer screening. Notably, there was a significant association between knowledge of breast cancer screening and attitude ( p = 0.027 ), and factors such as level of study ( p = 0.041 ), ethnicity ( p = 0.026 ), parity ( p = 0.018 ), and faculty of study ( p = < 0.001 ) influenced the participants’ knowledge. Conclusion. It is crucial to implement comprehensive awareness campaigns to address the negative attitude and poor screening practices among female university students regarding breast cancer. Additionally, providing free and widespread breast cancer screening services to students should be considered as a means to combat this disease.

The Sociocultural Influences on Breast Cancer Screening among Rural African Women in South Africa.

The incidence of breast cancer in South Africa is increasing, with rural South African women presenting with advanced stages of the disease. A woman's breasts are a symbol of her womanhood; they also constitute a social definition of her femininity. Women with breast cancer in rural South Africa are heavily stigmatized and suffer from various sociocultural interpretations of the disease. Breast cancer is frequently interpreted in rural South Africa as a symbol of witchcraft, sin, and punishment, and traditionally, it is treated by offering animal sacrifices, consumption of herbs, and prayer to ancestors. Using care-seeking behaviour theory as the theoretical framework, we intend to explore the sociocultural factors influencing breast cancer screening practices among rural South African women. A qualitative exploratory study was conducted using semi-structured interviews with 22 rural South African women selected by purposive sampling. Thematic analysis was used to analyse the data. The study identified four sociocultural factors influencing women's practices of breast cancer screening in rural South Africa, including psychological factors, habits, beliefs, and perceptions of healthcare. Women in rural South African communities have deep-rooted traditional beliefs and practices regarding breast cancer. Consequently, this influences women's preventative health behaviours regarding breast cancer screening. The development of culturally appropriate health education programs involving traditional healers and influential community leaders is essential to increasing the number of women being screened for breast cancer in rural South Africa.

Knowledge of breast cancer, willingness and barriers to mammography screening among rural women in Enugu State, Nigeria.

Breast cancer is a serious public health threat. Mammography is the most reliable screening method that detects breast cancer early, enabling early onset of treatment which improves the prognosis of the disease. To determine women's knowledge of breast cancer, as well as barriers and willingness of women to participate in mammography screening. Using the cross-sectional survey design, we sampled and studied two rural communities of Enugu State, Nigeria. Two researcher-made questionnaires were used for the study. Frequencies, percentages, chi-square and regression analysis were employed in data analysis. Only 11.4 percent of study participants had good knowledge of breast cancer. There were significant differences in knowledge of breast cancer based on level of education (χ2 = 15.670; p =.001), monthly income (χ2 =6.954; p = .021) and ever screened (χ2 =5.242; p =.015). Lack of money (48.0%) and lack of knowledge (30.4%) were the most reported barriers to breast cancer screening. Women that had ever screened were 92.3% less likely willing to be screened than those never screened (aOR: .077, 95%CI .011-.522, p=.009). Health Education should be combined with improving women's economic status and subsidizing the cost of screening to increase breast cancer screening practice.

Breast and cervical cancer screening practices in nine countries of Eastern Europe and Central Asia: A population-based survey

BackgroundEastern Europe and Central Asia (EECA) countries have higher cervical and breast cancer mortality rates and later stage at diagnosis compared with the rest of WHO European Region. The aim was to explore current early detection practices including “dispensarization” for breast and cervix cancer in the region. MethodsA questionnaire survey on early detection practices for breast and cervix cancer was sent to collaborators in 11 countries, differentiating services in the primary health setting, and population-based programs. Responses were received from Armenia, Belarus, Georgia, Kazakhstan, Kyrgyzstan, the Russian Federation (Arkhangelsk, Samara and Tomsk regions), Tajikistan, Ukraine, and Uzbekistan. ResultsAll countries but Georgia, Kyrgyzstan, and the Russian Federation had opportunistic screening by clinical breast exam within “dispensarization” program. Mammography screening programs, commonly starting from age 40, were introduced or piloted in eight of nine countries, organized at national oncology or screening centres in Armenia, Belarus and Georgia, and within primary care in others. Six countries had “dispensarization” program for cervix cancer, mostly starting from the age 18, with smears stained either by Romanowsky-Giemsa alone (Belarus, Tajikistan and Ukraine), or alternating with Papanicolaou (Kazakhstan and the Russian Federation). In parallel, screening programs using Papanicolaou or HPV test were introduced in seven countries and organized within primary care. ConclusionOur study documents that parallel screening systems for both breast and cervix cancers, as well as departures from evidence-based practices are widespread across the EECA. Within the framework of the WHO Initiatives, existing opportunistic screening should be replaced by population-based programs that include quality assurance and control.

Breast Cancer Risk Assessment and Screening Practices Reported Via an Online Survey.

Breast cancer screening guidelines differ between organizations, and significant variations in practice patterns exist. Previous evidence suggests that provider-level factors are the greatest contributors to risk assessment and screening practice variability. This study aimed to characterize provider factors associated with breast cancer risk assessment and screening practice patterns, and to assess perceived barriers to providing risk assessment. An online survey was distributed to providers at a single academic institution and to providers publicly via social media (January to August 2022). Respondents in the United States who care for adult women at risk for the development of breast cancer were included. Most of the respondents in the 143 completed surveys were white/Caucasian (79%) females (90%) age 50 years or younger (79%), and whereas 97% discuss breast cancer screening with their patients, only 90% order screening mammograms. Risk factor assessment was common (93%), typically performed at the first visit (51%). Additional training in genetics or risk assessment was uncommon (17%), although the majority were interested but did not have the time or resources (55%). Although most (64%) did not perceive barriers to providing risk assessment or appropriate screening, the most common barriers were time (77%) and education (55%). Barriers were more common among family practice or obstetrics and gynecology (OB/GYN) providers and those who worked in an academic setting (all p < 0.05). Breast cancer risk assessment and screening practices are highly variable. Although time is the major barrier to providing risk assessment, providers also need education. Primary care organizations could partner with breast cancer-focused societies for additional resources.

How does the war affect breast cancer quality of care? The Syrian experience.

e18724 Background: The Syrian decade-long war has severely affected the healthcare system, including almost vanishing cancer screening practices, war-destroyed medical facilities, and lack of continuous medical education. This study aims to present data on the affected breast cancer screening practices, methods of diagnosis, and stages distribution in Syria. Methods: Medical records of breast cancer patients treated at Albairouni University Hospital between 2019 and 2022 were retrospectively reviewed. Eligible patients were women diagnosed with primary breast cancer. Exclusion criteria included male gender, females receiving neoadjuvant chemotherapy, and incomplete charts. Data regarding the patient's age, city of residence, marital status, number of children, smoking habits, method of diagnosis, tumor size (T), lymph nodes (N), and distal metastasis (M) were collected. We used Microsoft Excel and Statistical Package for the Social Sciences (SPSS) to analyze data. Descriptive methodology (frequency [n], percentage) was used. Results: The number of included patients after applying the exclusion criteria was 2,367. The mean age was 51.8 (SD = 11.3). More than half of the patients (58.3%) came from outside Damascus -where the hospital is located- and its suburbs. Less than 5% of the population detected cancer by screening mammography. Only 32.4% of patients were diagnosed by a biopsy, while surgical procedures were used to diagnose 64.8% of the population. At the time of diagnosis, only 8% of patients presented with local-stage disease (stages 0 &amp; I), 73% had a regional disease (stages II &amp; III), and 19% had metastatic breast cancer (stage IV). Conclusions: Our retrospective chart review analysis is the first comprehensive review in Syria for female breast cancer patients. We found a chocking low percentage of patients diagnosed based on a screening mammogram, much higher surgical biopsies rather than a simple imaging-guided biopsy, and much lower than the national average of early-stage disease. Factors that might explain our results include lack of appropriate education, restricted access to medical facilities, and financial restraints. Our alarming findings can serve as the base for future strategies to improve breast cancer care in Syria by detecting the disease earlier and avoiding surgical diagnostic procedures.

Scientific uncertainty and perceived mammography benefits in women screened for breast cancer

Personal aversion to scientific uncertainty may influence how women perceive the benefits of mammography, a breast cancer screening practice with conflicting scientific opinions and guidelines. Such associations may even exist among women who participate in screening. We evaluated the distribution of aversion to ambiguous medical information (AA-Med), using a 6-item scale capturing the level of agreement with statements about obtaining a cancer screening test with conflicting medical recommendations in 665 women (aged 40-60years; 79.5% Hispanic) recruited during screening mammography appointments in New York City. We assessed the association of AA-Med with perceptions of benefits of mammography (breast cancer mortality reduction, worry reduction, early detection, treatment improvement) using multivariable logistic regression. Over a quarter of participants expressed negative reactions to medical ambiguity about a cancer screening test (e.g., fear, lower trust in experts), but a majority endorsed intention to undergo screening. AA-Med was higher in women who were U.S.-born, non-Hispanic black, and had marginal to adequate health literacy, but there were no differences by clinical factors or screening experiences (e.g., family history, prior breast biopsy). Women with higher AA-Med were more likely to perceive treatment benefits from mammography (OR = 1.37, 95% CI = 0.99-1.90), but AA-Med was not associated with other perceived mammography benefits. Aversion to uncertainty regarding cancer screening varies by sociodemographic characteristics but has limited associations with perceived mammography benefits in women who already participate in screening.

Abstract 1941: Barriers and effective interventions to engage Latinas' participation in breast cancer clinical trials

Abstract Breast cancer is the most diagnosed cancer among Latina women and is the leading cause of cancer-related death among Latinas (16.6%). While The Latino population is one of the fastest-growing populations in the US, they are severely underrepresented in clinical trials. Latinos make up 17% of the population but only 1% of clinical trial participants. Of clinical trials published covering 2001-2010, Latinos’ enrollment constituted only 2.2% of accrued participants. The percentage of Latino participants narrows down when we separate by gender. The goal of this study is to examine the prevalence of breast cancer-related barriers among Latinas and to determine the extent to which these barriers might influence Latinas enrolling in breast cancer clinical trials. If language and religion are the reason Latinas enroll less in breast cancer clinical trials, then increasing the availability of translated materials and a priest of a Catholic Church advertising the breast cancer studies will increase the enrollment rate of Latinas. Semi-constructed interviews were conducted with two Latino organizations to understand current barriers Latina’s face within the medical field. Based on these findings, I conducted an intervention at Our Lady of Tepeyac Church consisting of an information booth, making an announcement regarding Research Study 9127, and having bilingual Latinas available to give out more information while helping them enroll in Research Study 9127. At the end of the church intervention, 33 Latinas were enrolled in Research Study 9127, seeing a 550% increase in Latinas participating in Research Study 9127. Latinx women remain severely underrepresented in breast cancer clinical trials, thus limiting the generalizability of cancer clinical research, but interventions across churches would lead to improvements in general cancer knowledge, breast cancer screening practices, and intentions to enroll in clinical trials. This study can inform efforts to increase clinical trial participation in Latinas by highlighting important motivators to participation specific to Latinas and informing future interventions aimed at encouraging participation in clinical trials in a culturally sensitive and effective way.
