Breast cancer screening practice and associated factors: Women's Health Survey in Uberaba MG Brazil, 2014

Comprehensive diagnosis of advanced-stage breast cancer: exploring detection methods, molecular subtypes, and demographic influences - A cross-sectional study

BACKGROUND

Brazil faces notable Breast Cancer (BC) mortality despite lower incidence rates versus developed countries. Despite guidelines from medical societies, Brazilian public policy recommends biennial mammographic screening for women aged 50 to 69. This study investigates sociodemographic and clinical factors related to BC detection methods and clinical stage at diagnosis.

METHODS

The authors conducted a cross-sectional study at a São Paulo tertiary hospital. Patients were divided into 'symptomatic' and 'mammographic' detection groups. Bivariate analyses by detection method and clinical stage compared groups' profiles in terms of sociodemographic and clinical characteristics. Poisson regression analyses assessed sociodemographic and molecular subtypes´ influence on "mammographic detection" prevalence and "advanced-stage BC", reporting prevalence ratios and 95 % Confidence Intervals.

RESULTS

The authors studied 1,536 BC patients admitted from January 2016 to December 2017. The "mammographic detection" group had a higher proportion of patients aged 50‒69 years (62.9 % vs. 44.1 %), white race (63.3 % vs. 51.6 %), Catholic religion (58.2 % vs. 51.1 %), and Luminal A subtype (25.2 % vs. 13.2 %) compared to the "symptomatic detection" group. Patients with early-stage disease were more likely to have higher education levels (8.1 % vs. 5.5 %) and be married (39.8 % vs. 46.6 %) compared to those with advanced-stage. Molecular subtypes were significantly associated with the detection method and stage. The prevalence of advanced-stage disease in "mammographic" (n=313) and "symptomatic" (n=1191) groups was 18.5 % and 55 %, respectively . Mammographic detection significantly reduced advanced-stage BC prevalence (PR = 0.40, 95 % CI 0.31‒0.51).

CONCLUSION

Mammographic detection reduces advanced-stage breast cancer prevalence in Brazil, emphasizing the importance of regular screenings, especially among at-risk sociodemographic groups. Enhancing mammographic screening accessibility, lowering the starting age to 40, and extending coverage to include annual mammograms can significantly lower breast cancer mortality in Brazil, benefiting public health and patient outcomes.

Breast cancer pre-clinical screening using infrared thermography and artificial intelligence: a prospective, multicentre, diagnostic accuracy cohort study

BACKGROUND

Given the limited access to breast cancer (BC) screening, the authors developed and validated a mobile phone-artificial intelligence-based infrared thermography (AI-IRT) system for BC screening.

MATERIALS AND METHODS

This large prospective clinical trial assessed the diagnostic performance of the AI-IRT system. The authors constructed two datasets and two models, performed internal and external validation, and compared the diagnostic accuracy of the AI models and clinicians. Dataset A included 2100 patients recruited from 19 medical centres in nine regions of China. Dataset B was used for independent external validation and included 102 patients recruited from Langfang People's Hospital.

RESULTS

The area under the receiver operating characteristic curve of the binary model for identifying low-risk and intermediate/high-risk patients was 0.9487 (95% CI: 0.9231-0.9744) internally and 0.9120 (95% CI: 0.8460-0.9790) externally. The accuracy of the binary model was higher than that of human readers (0.8627 vs. 0.8088, respectively). In addition, the binary model was better than the multinomial model and used different diagnostic thresholds based on BC risk to achieve specific goals.

CONCLUSIONS

The accuracy of AI-IRT was high across populations with different demographic characteristics and less reliant on manual interpretations, demonstrating that this model can improve pre-clinical screening and increase screening rates.

Predictive Factors for the Risk of Sexual Dysfunction in Climacteric Women: Population-based Study

BACKGROUND

It is known that sexual problems increase with age but little is known about the predictors of female sexual dysfunction (FSD) in Brazilian climacteric women.

AIM

To identify predictive factors for FSD in climacteric women.

METHODS

This is a cross-sectional population-based study carried out through a household survey.

OUTCOMES

The measures investigated were sociodemographic characteristics, depressive symptoms, level of physical activity, presence of FSD, self-rated health and sleep satisfaction.

RESULT

A total of 381 climacteric, sexually active women were included, with a mean age of 55.04 (±7.21) years. The prevalence of FSD was 38.3%. All variables investigated were associated with FSD (P < .05). In the final model, the predictors for FSD were low satisfaction with sleep (OR 4.20; 95% CI 2.32-7.62), advanced age (OR 1.04; 95% CI 1.00-1.08), low education level (OR 0.90; 95% CI 0.85-0.97) and having a partner (OR 0.35; 95% CI 0.16-0.76).

CLINICAL IMPLICATION

These aspects deserve attention from the health team to prevent and identify FSD early in life in climacteric women.

STRENGTHS & LIMITATIONS

This study support existing data about risk factors for FSD in climacteric women. However, it is not possible to attribute causality to any of the correlates identified, which is a limitation of cross-sectional studies.

CONCLUSION

Dissatisfaction with sleep, senility, insufficient income, low education, not having a partner, complaints of depression, and the worse perception of global health are predictive factors for FSD in climacteric women.

Determinants of Lack of Access to Treatment for Women Diagnosed with Breast Cancer in Brazil

Access to timely treatment is essential for the probability of the cure and reduction of severe breast cancer cases. In Brazil, legislation states that cancer treatment must start within 60 days of diagnosis. This study analyzed the factors associated with lack of access to breast cancer treatment in women with a confirmed diagnosis inserted in the health system. We collected secondary data from Brazilian women with a diagnosis and without treatment from January to December 2019 through the Cancer Hospital Registers developed by the National Cancer Institute. Our findings indicate that most women (60.11%) are diagnosed with stage II cancer but are without treatment. Most of them are aged 18–70 years, non-white race/color, have a low educational level and are from the Southeast Brazilian region. In addition, social inequalities are determinant in women’s lack of access to breast cancer treatment.

Association of Late Marriage and Low Childbirth with Cervical Cancer Screening among Korean Women: Results from a Nationwide Survey

Simple Summary

Marriage and childbirth may affect adherence to cervical cancer screening. We have examined whether marriage and childbirth were associated with the adherence to cervical cancer screening among young adult women in Korea. Among 3925 women aged 20–39 years, 39.1% undertook cervical cancer screening within two years of eligibility. Compared with unmarried women, married women were more likely to adhere cervical cancer screening (adjusted odds ratio = 2.80, 95% CI: 2.99–3.44). And, as the number of births in married women increased, the adherence to cervical cancer screening increased.

Abstract

This study aimed to identify the association of marriage and childbirth with the adherence to cervical cancer screening among young adult women. Data across four years (2017–2020) of the cross-sectional Korean National Cancer Screening Survey were used. For measuring the adherence to cervical cancer screening, we used the cervical cancer screening rate with recommendation, which was defined as the percentage of women in the population eligible for screening who have had a cervical cancer screening within the past two years. Multiple logistic regression analysis was conducted to identify the association between marriage and adherence to cervical cancer screening. Overall, 3925 women aged 20–39 years were analyzed. Of these, 39.1% were screened for cervical cancer (26.6% unmarried and 57.1% married women). The married women had significantly higher adherence to cervical cancer screening than unmarried women (adjusted odds ratio = 2.80, 95% CI: 2.99–3.44). Compared with unmarried women, adherence to cervical cancer screening was significantly more likely to increase (p for trend, <0.001) in married women with an increased number of births. Our study confirmed that marriage and childbirth influence adherence to cervical cancer screening, suggesting that unmarried women may be vulnerable to cervical cancer.

Breast Cancer Screening Practice and Associated Factors Among Women Aged 20-70 Years in Urban Settings of SNNPR, Ethiopia

Background

Breast cancer is the leading cause of morbidity and mortality among women in many countries around the globe. Early detection of breast cancer plays a great role in cancer prevention and treatment by potentially decreasing mortality. However, evidence is sparse on breast cancer screening practice among women in southern Ethiopia. Therefore, the aim of this study was to assess breast cancer screening practice and associated factors among women 20–70 years of age in an urban setting in SNNPR, Ethiopia.

Methods

A community-based cross-sectional study was conducted from March to April 2020. Multistage sampling technique was applied to select the study participants. Data were collected by using a pretested interviewer-administered structured questionnaire. Bivariable and multivariable logistic regression was done to confirm association between dependent variable and covariates.

Results

From the total study participants, 83 (13.6%; 95%CI: 10.8, 16.4%), have regularly engaged in at least one breast cancer screening method. Women with a favorable attitude towards breast cancer and its screening (AOR=3.0; 95%CI: 1.63–5.56), educational status of college and above (AOR=3.8; 95%CI: 1.25– 11.48), family history of breast cancer (AOR=3.7; 95%CI: 1.73–7.96), awareness about breast cancer screening methods (AOR=3.0; 95%CI: 1.46–6.22), knowing someone screened for breast cancer (AOR=2.2; 95%CI: 1.10–4.38), and recommendation by health professionals for BCS (AOR=5.0; 95%CI: 2.35–10.68) were variables significantly associated with BCS practice.

Conclusion

Breast cancer screening practice is low. Women with college and above education level, favorable attitude towards breast cancer and its screening, awareness about breast cancer screening methods, family history of breast cancer, having a recommendation from health professionals and knowing someone who screened for breast cancer were associated with BCS practice. Therefore, this finding implies the need to intervene upon those factors.

Health Iniquity, Unhealthy Behavior, and Coverage of Mammography in Brazil

OBJECTIVE

To investigate the prevalence of mammography screening and the association among socio-demographic, behavior factors and non-adherence to mammography screening among women between 50 and 69 years old, using data from Vigitel 2016.

METHOD

Cross-sectional, population-based study with data from Vigitel including 12,740 women in the 50-69 age group. The variables were analyzed using logistic regression.

RESULTS

Among the women studied, 21.8% had not had a mammography in the past 2 years. The characteristics associated with non-adherence to the test were having less than 12 years of education (p<0.001), having no partner (p=0.001), being underweight (p=0.002), having a negative self-perceived health status (p<0.001) and having at least one negative health behavior (p<0.001).

CONCLUSION

There is a subgroup of women with markers of social vulnerability, which reflect the inequality in mammography screening.

Factors related to mammography adherence among women in Brazil: A scoping review

AIM

To explore and synthesize the literature on factors related to mammography screening adherence among women in Brazil.

DESIGN

A scoping review.

METHODS

We searched 11 databases for studies published between 2006-January 2020. All identified articles were screened, and data were extracted from eligible studies. We used the UK Government Social Research Service weight of evidence appraisal tool to appraise the quality of the included study.

RESULTS

From a total of 1,384 identified articles, 22 were retained. All included studies used quantitative, non-experimental methods and all but two studies used cross-sectional data. Quality of evidence varied across studies. We identified 41 factors that were investigated across the set of studies. Demographic and socio-economic factors were the most commonly investigated, with older age, urban residence, living in the southeast of Brazil, higher level of education, higher income and private health insurance most consistently associated with mammography adherence.

Temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service between 2008 and 2017

BACKGROUND

In Brazil, 70% of the population depends on the public healthcare system. Since early detection is considered crucial, this study aimed to evaluate temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service (SUS) according to the different regions of the country between 2008 and 2017.

METHODS

This ecological study analyzed data on breast cancer screening within the SUS for women aged 50-69 years. Coverage was calculated from the ratio between the number of screening tests conducted and the expected number for the target population. Joinpoint regression analysis was used to calculate annual percent changes (APC) in coverage.

RESULTS

Around 19 million mammograms were performed in 50-69-year old women within the SUS between 2008 and 2016. The estimated APC indicates that breast cancer screening coverage increased by 14.5% annually in Brazil between 2008 and 2012 (p < 0.01), with figures stabilizing between 2012 and 2017 as shown by an APC of - 0.4% (p = 0.3). In the five geographic regions of the country, the APC initially increased, then stabilized in the north, northeast and southeast and decreased in the south and Midwest. Of the 26 states, coverage increased in seven and remained stable in six. In the other 13, there was an initial increase followed by stabilization in 11, and a reduction in coverage in two. In the Federal District, coverage remained stable throughout the study period.

CONCLUSION

Evaluation of the temporal changes in breast cancer screening coverage provided under the Brazilian National Health Service revealed an initial increase, confirming that public policies were effective, although insufficient to ensure organized screening. There appears to be a lack of uniformity between the different regions and states and this situation is highlighted in the final 5-year period, with the APC reflecting stabilization of breast cancer screening coverage.
