Inequality by Skin Color in Breast Cancer Screening in Brazil: a Differences-in-Differences Analysis of the COVID-19 Pandemic. J Racial Ethn Health Disparities 2024:10.1007/s40615-024-01908-2. [PMID: 38228863 DOI: 10.1007/s40615-024-01908-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Revised: 12/28/2023] [Accepted: 01/04/2024] [Indexed: 01/18/2024]
Abstract
Breast cancer is the second most common cancer type and the first in mortality among Brazilian women. Mammograms are one of the main early diagnosis strategies. National breast cancer screening coverage is still low. Brazil's low screening coverage is due to high mammography access inequality. Skin color defines healthcare access differences. Our article explores the natural event of the COVID-19 pandemic to analyze differences in screening rates between two racial groups of women through the application of the differences in differences (DiD) estimator. The results indicate that BBI women (Black, Brown, and Indigenous Brazilian) have lower screening rates than WY women (White and Yellow) and that the pandemic reduced the difference between these two groups due to the lower number of mammograms performed by WY women. It is believed that the information channel can explain much of this result. The BA population, wealthier and more educated, may have had additional information about COVID-19 and its consequences, as well as an increased likelihood of working remotely and practicing social distance. Structural racism causes many social indicators to be correlated with inequality of access to mammography and negatively impacts health conditions for BBI women. Public policies are necessary for equal access to breast cancer screening for the most vulnerable women.

Assessment of Sexual Health and Use of Cervical Cancer Screening among the Female Working Population. IRANIAN JOURNAL OF PUBLIC HEALTH 2024; 53:198-207. [PMID: 38694863 PMCID: PMC11058389 DOI: 10.18502/ijph.v53i1.14696] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 10/09/2023] [Indexed: 05/04/2024]
Abstract
Background Cervical cancer occupies a significant place in the overall structure of morbidity and mortality in developing countries. We focused on the sexual health and use of cervical cancer screening among the female working population of reproductive age in Central Serbia. Methods The research was conducted as a cross-sectional study, according to the methodology Stepwise approach to noncommunicable disease risk factor surveillance WHO. The study population consisted of 1182 female working population aged 18-49 years, living on the territory of Central Serbia. The method of simple random sampling was utilized in the research itself. An anonymous standardized questionnaire was used as a research tool. Results During the first sexual intercourse, 38.9% of the participants reported not having used any of the contraceptives, whereas 74.5% of the participants reported not having used them during their last sexual intercourse and 26.1% of the respondents reported not having had a single Pap smear in their lifetime. The multivariate logistic regression analysis singled out the following factors in women who reported not having done a Pap smear in their lifetime as the most significant ones: age - the youngest age group (OR = 3.30, CI = 1.80-6.04), unemployment (OR = 2.87, CI = 0.07-3.40), women who had never been married or had never been in a common-law marriage (OR = 2.55, CI = 1.40-4.66) and individuals with a medium education level (OR = 2.63, CI = 1.67-4.14). Conclusion In Serbia, all the activities should be directed towards increasing the levels of awareness and knowledge on sexual health and cervical cancer screening services.

Papanicolaou test in Brazil: analysis of the National Health Survey of 2013 and 2019. Rev Saude Publica 2023; 57:55. [PMID: 37878841 PMCID: PMC10519687 DOI: 10.11606/s1518-8787.2023057004798] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2022] [Accepted: 09/26/2022] [Indexed: 10/27/2023] Open
Abstract
OBJECTIVES To compare the coverage of cervical cancer screening in Brazil in 2013 and 2019, investigating the factors associated with having the test performed and the reasons given for not doing it. Additionally, a comparison is made concerning the time taken to receive the test result in SUS (Sistema Único de Saúde) and in the private health services. METHODS Using data from the National Health Survey (Pesquisa Nacional de Saúde - PNS), prevalence rates and corresponding confidence intervals were calculated to determine the frequency of recent cervical cancer screenings among women aged between 25 and 64 years old in Brazil, for both 2013 and 2019. Poisson regression models were employed to compare the prevalence of the outcome according to sociodemographic characteristics. The reasons for not having the test and the time between performing and receiving the result were also analyzed. RESULTS The findings revealed an increase in the coverage of preventive cervical cancer exams in Brazil from 78.7% in 2013 to 81.3% in 2019. Additionally, there was a decline in the proportion of women who had never undergone the exam, from 9.7% to 6.1%. Prevalence of test uptake was higher among white women, those with higher levels of education and income, and those residing in the South and Southeast regions of the country. The most commonly cited reasons for not taking the test were the impression it was unnecessary (45% in both 2013 and 2019) and never having been asked to undergo the test (20.6% in 2013 and 14.8% in 2019). CONCLUSIONS Despite the high coverage of screening achieved in the country, there is great inequality in access to the test, and a non-negligible number of women are at greater risk of dying from a preventable disease. Efforts must be made to structure an organized screening program that identifies and captures the most vulnerable women.

Factors that Affect Performance of Clinical Breast Examination and Mammography Screening among Brazilian Women. Asian Pac J Cancer Prev 2023; 24:3477-3486. [PMID: 37898853 PMCID: PMC10770697 DOI: 10.31557/apjcp.2023.24.10.3477] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Accepted: 10/19/2023] [Indexed: 10/30/2023] Open
Abstract
BACKGROUND In the Brazilian health system, community health facilities consist of multidisciplinary teams that focus on family health, whereas health centers treat mainly illnesses of registered patients. In the present study we compared socio-economic factors and performance of mammography screening (MS) and clinical breast exam (CBE), respectively, among women who used both types of public health service centers. METHODS The present study included 180 women aged ≥40 years, who used different health service centers within the same municipal district. Of all 180 women, 110 (41.1%) and 70 (38.9%) used a health center and a community health facility. Logistic regression analysis was performed to calculate odds ratios (ORs) and confidence intervals (CIs) of variables. RESULTS Regression modeling indicated that women who used the community health facility, performed annual MS 9.52 (OR= 0.105; 95%CI: 0.03- 0.36) times more often (p <0.001). In this model retirement and gynecological service use ≤ each second year, increased annual MS performance 8.16 (95%CI: 1.55- 54.32) and 7.78 (95%CI: 2.54- 23.79) times (p <0.001; p <0.001). Among 113 (62.8%) women who reported strong fear of MS, the chance of its performance was 35.71 (OR= 0.028; 95%CI: 0.02- 0.32) times decreased (p= 0.05). In a second model use of gynecological service ≤ each second year, increased chance of annual CBE performance 7.92 (95%CI: 3.25- 19.29) times (p <0.001). Women who used the community health facility performed annual and bi-annual CBE 2.90 (OR= 0.345; 95%CI: 0.14- 0.86) and 2.97 (OR= 0.337; 95%CI: 0.12- 0.92) times more often, compared to women who used the health center (p =0.030). CONCLUSIONS Performance of MS and CBE varied both considerable among women who used different types of health service centers. Gynecological service use, fear and socioeconomic variables, additionally influenced regular performance of MS and CBE.

Cancer inequalities in incidence and mortality in the State of São Paulo, Brazil 2001-17. Cancer Med 2023; 12:16615-16625. [PMID: 37345901 PMCID: PMC10469722 DOI: 10.1002/cam4.6259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2023] [Revised: 06/02/2023] [Accepted: 06/05/2023] [Indexed: 06/23/2023] Open
Abstract
BACKGROUND Cancer disparities exist between and within countries; we sought to compare cancer-specific incidence and mortality according to area-level socioeconomic status (SES) in the State of São Paulo, Brazil. METHODS Cancer cases diagnosed 2003-2017 in the Barretos region and 2001-2015 in the municipality of São Paulo were obtained from the respective cancer registries. Corresponding cancer deaths were obtained from a Brazilian public government database. Age-standardized rates for all cancer combined and the six most common cancers were calculated by SES quartiles. RESULTS There were 14,628 cancer cases and 7513 cancer deaths in Barretos, and 472,712 corresponding cases and 194,705 deaths in São Paulo. A clear SES-cancer gradient was seen in São Paulo, with rates varying from 188.4 to 333.1 in low to high SES areas, respectively. There was a lesser social gradient for mortality, with rates in low to high SES areas ranging from 86.4 to 98.0 in Barretos, and from 99.2 to 100.1 in São Paulo. The magnitude of the incidence rates rose markedly with increasing SES in São Paulo city for colorectal, lung, female breast, and prostate cancer. Conversely, both cervical cancer incidence and mortality rose with lower levels of SES in both regions. CONCLUSIONS A clear SES association was seen for cancers of the prostate, female breast, colorectum, and lung for São Paulo. This study offers a better understanding of the cancer incidence and mortality profile according to SES within a highly populated Brazilian state.

Abstract
OBJECTIVE To estimate prevalence, assess trends and identify factors associated with non-performance of Pap smears among postpartum women residing in Rio Grande, Southern Brazil. METHODS Between 01/01 and 12/31 of 2007, 2010, 2013, 2016 and 2019, previously trained interviewers applied a single standardized questionnaire at the hospital to all postpartum women residing in this municipality. It was investigated from the planning of pregnancy to the immediate postpartum period. The outcome consisted of not performing a Pap smear in the last three years. The chi-square test was used to compare proportions and assess trends, and Poisson regression with robust variance adjustment in the multivariate analysis. The measure of effect was the prevalence ratio (PR). RESULTS Although 80% of the 12,415 study participants had performed at least six prenatal consultations, 43.0% (95%CI 42.1-43.9%) had not been screened in the period. This proportion ranged from 64.0% (62.1-65.8%) to 27.9% (26.1-29.6%). The adjusted analysis showed a higher PR for not performing Pap smears among younger puerperal women, living without a partner, with black skin color, lower schooling, and family income, who did not have paid work during pregnancy or planned pregnancy, who attended fewer prenatal consultations. smoked during pregnancy and were not being treated for any illness. CONCLUSION Despite the improvement in coverage, the observed rate of non-performance of Pap smears is still high. Women most likely to have cervical cancer were those who had the highest PR for not having this test.

Recent changes in trends of mortality from cervical cancer in Southeastern Brazil. Rev Saude Publica 2023; 57:25. [PMID: 37075421 PMCID: PMC10118416 DOI: 10.11606/s1518-8787.2023057004709] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/18/2022] [Accepted: 07/08/2022] [Indexed: 04/21/2023] Open
Abstract
OBJECTIVE To analyze the trends of cervical cancer mortality in Brazilian Southeastern states, and to compare them to Brazil and other regions between 1980 and 2020. METHODS Time series study based on data from the Sistema de Informações de Mortalidade (Brazilian Mortality Information System). Death data were corrected by proportional redistribution of deaths from ill-defined causes and cervical cancer of unspecified portion. Age-standardized and age-specific rates were calculated by screening target (25-39 years; 40-64 years) and non-target (65 years or older) age groups. Annual percentage changes (APC) were estimated by linear regression model with breakpoints. The coverage of Pap Smear exam in the Unified Health System (SUS) was evaluated between 2009 and 2020 according to age group and locality. RESULTS There were increases in corrected mortality rates both in 1980 and in 2020 in all regions, with most evident increments at the beginning of the series. There was a decrease in mortality nationwide between 1980-2020; however, the state of São Paulo showed a discrete upward trend in 2014-2020 (APC=1.237; 95%CI 0.046-2.443). Noteworthy is the trend increment in the 25-39 year-old group in all study localities, being sharper in the Southeast region in 2013-2020 (APC=5.072; 95%CI 3.971-6.185). Screening coverage rates were highest in São Paulo and lowest in Rio de Janeiro, with a consistent decline from 2012 onwards at all ages. CONCLUSIONS São Paulo is the first Brazilian state to show a reversal trend in mortality from cervical cancer. The changes in mortality patterns identified in this study point to the need for reorganization of the current screening program, which should be improved to ensure high coverage, quality, and adequate follow-up of all women with altered test results.

A nationwide pilot study on breast cancer screening in Peru. Ecancermedicalscience 2023; 17:1494. [PMID: 36816782 PMCID: PMC9937072 DOI: 10.3332/ecancer.2023.1494] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Indexed: 01/11/2023] Open
Abstract
Introduction A high prevalence of advanced breast cancer (BC) is a common scenario in Latin America. In Peru, the frequency of BC at Stages III/IV is ≈50% despite implementation of a programme for breast cancer screening (BCS) along the country. We carried out a study to assess the feasibility and develop an instrument to evaluate the knowledge, barriers and perception about BCS in a nationwide pilot study in Peru among candidates for BCS. Methods We conducted a systematic review of 2,558 reports indexed in PubMed, Scopus, Web of Science, Medline-Ovid and EMBASE, regarding to our study theme. In total, 111 were selected and a 51-items survey was developed (eight items about sociodemographic characteristics). Patients were recruited in public hospitals or private clinics, in rural and urban areas of nine departments of Peru. Results We surveyed 488 women from: Lima (150), Cajamarca (93), Ica (59), Arequipa (56), Loreto (48), Ancash (38), Junín (15), Puerto Maldonado (15) and Huancavelica (14); 27.9% of them were from rural areas. The mean of age was 53.3 years (standard deviation ± 9.1). Regarding education level, 29.8% had primary, 33.2% secondary and 37.0% higher education. In total, 28.7% of women did not know the term 'mammogram' and 47.1% reported never receiving a BCS (36.9% from urban and 73.5% from rural population). In women that underwent BCS, only 67% knew it is for healthy women. In total, 54.1% of patients had low levels of knowledge about risk factors for BC (i.e. 87.5% of women respond that injuries in the breast produce cancer). Cultural, economic and geographic barriers were significantly associated with having a mammogram where 56.9% of participants considered a cost ≤ 7 USD as appropriate. Mammogram was perceived as too painful for 54.9% of women. In addition, women with a self-perception of low-risk for BC and a fatalistic perception of cancer were less likely to have a BCS. Conclusion We found that it is feasible to conduct a large-scale study in Peru. The results of this pilot study highlight an urgent need of extensive education and awareness about BCS in Peru.

Abstract
This study analyzes the performance of screening and diagnosis tests for cervical cancer among women aged 25 to 64 years, as well as the delay for the initiation of treatment within Brazil and in its geographic regions, from 2013 to 2020. Information on populational procedures and estimates was obtained from the information systems of the Brazilian Unified National Health System and the Brazilian National Supplementary Health Agency. We calculated the coverage indicators of the Pap smear, the percentages of altered cytopathological and histopathological tests, and the percentage of women diagnosed with cervical cancer with over 60 days of treatment. There was great variation in the coverage of the Pap smear test among the Brazilian regions with a downward trend from 2013, which was aggravated from 2019 to 2020. The number of altered cytopathological tests was 40% lower than estimated, and the difference between the recorded number of cancer diagnoses and the estimated number of patients was below 50%. The percentage of women diagnosed with invasive cervical cancer, who started treatment after 60 days, ranged from 50% in the South to 70% in the North Region with a decrease from 2018. In 2020, there was a decrease in the number of screening and follow-up tests, reducing the proportion of women delayed in starting treatment in the North, Southeast, and South regions. The decline in screening coverage and inadequate follow-up of women with altered results indicate the need to improve early detection strategies for the disease and establish mechanisms for constant evaluation and monitoring of actions.

Abstract
The study aimed to investigate the knowledge, attitudes and practices of professionals of the Family Health Strategy (FHS) on the control of uterine cervical cancer (CCU) recommended by the Ministry of Health (MS). This is a cross-sectional study, which used a self-administered questionnaire with the doctors and nurses of the FHS of Juiz de Fora, MG, in 2019. For analysis, the chi-square and Fisher's exact test were used, 5% level of significance. Among the 170 surveyed, which corresponded to 93% of FHS professionals in the city, the prevalence of adequate knowledge was 39.4% and had association with younger age and female gender. The prevalence of an adequate attitude was 59.5% and of appropriate practices 77.6%, both associated with a longer time since graduation. The presence of the Ministry of Health guidelines in the units was associated with the outcomes, knowledge and adequate practice, confirming the importance of support material for consultation by professionals. Only 28.2% of professionals reported having received training in the last 3 years and 50.3% carried out educational actions for users. The need for permanent education actions with professionals is highlighted, aiming at a more effective action to confront and eradicate CCU.

Inequalities in Temporal Effects on Cervical Cancer Mortality in States in Different Geographic Regions of Brazil: An Ecological Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2022; 19:5591.

Abstract
Cervical cancer is a public health issue with high disease burden and mortality in Brazil. The objectives of the present study were, firstly, to analyze age, period, and cohort effects on cervical cancer mortality in women 20 years old or older from 1980 to 2019 in the North, South, and Southeast Regions of Brazil; and secondly, to evaluate whether the implementation of a national screening program and the expansion of access to public health services impacted the examined period and reduced the risk of death compared with previous years and among younger cohorts. The effects were estimated by applying Poisson regression models with estimable functions. The highest mortality rate per 100,000 women was found in Amazonas (24.13), and the lowest in São Paulo (10.56). A positive gradient was obtained for death rates as women's age increased. The states in the most developed regions (South and Southeast) showed a reduction in the risk of death in the period that followed the implementation of the screening program and in the cohort from the 1960s onwards. The North Region showed a decreased risk of death only in Amapá (2000-2004) and Tocantins (1995-2004; 2010-2019). The findings indicate that health inequities remain in Brazil and suggest that the health system has limitations in terms of decreasing mortality associated with this type of cancer in regions of lower socioeconomic development.

Abstract
Breast cancer is a multifaceted disease that currently represents a leading cause of death in women worldwide. Over the past two decades (1998–2020), the National Health Laboratory Service’s Human Genetics Laboratory in central South Africa screened more than 2,974 breast and/or ovarian cancer patients for abnormalities characteristic of the widely known familial breast cancer genes, Breast Cancer gene 1 (BRCA1) and Breast Cancer gene 2 (BRCA2). Patients were stratified according to the presence of family history, age at onset, stage of the disease, ethnicity and mutation status relative to BRCA1/2. Collectively, 481 actionable (likely-to pathogenic) variants were detected in this cohort among the different ethnic/racial groups. A combination of old (pre-2014) and new (post-2014) laboratory techniques was used to identify these variants. Additionally, targeted genotyping was performed as translational research revealed the first three recurrent South African pathogenic variants, namely BRCA1 c.1374del (legacy name 1493delC), BRCA1 c.2641G>T (legacy name E881X) and BRCA2 c.7934del (legacy name 8162delG). This initial flagship study resulted in a cost-effective diagnostic test that enabled screening of a particular ethnic group for these variants. Since then, various non-Afrikaner frequent variants were identified that were proven to represent recurrent variants. These include BRCA2 c.5771_5774del (legacy name 5999del4) and BRCA2 c.582G>A, both Black African founder mutations. By performing innovative translational research, medical science in South Africa can adopt first-world technologies into its healthcare context as a developing country. Over the past two decades, the progress made in the public sector enabled a pivotal shift away from population-directed genetic testing to the screening of potentially all breast and ovarian cancer patients, irrespective of ethnicity, family history or immunohistochemical status. The modifications over the years complied with international standards and guidelines aimed at universal healthcare for all. This article shares all the cohort stratifications and the likely-to pathogenic variants detected.

Abstract
Resumo: Este estudo teve como objetivo verificar a tendência temporal e desigualdades no rastreamento autorrelatado do câncer de colo de útero nas capitais brasileiras entre os anos de 2011 e 2020. Estudo de tendência com dados da Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) de 2011 a 2020. O desfecho foi a prevalência de realização de exame citopatológico nos últimos três anos. Para estimar as desigualdades, foram utilizados os índices de desigualdade de inclinação (slope index of inequality - SII) e de concentração (concentration index - CIX). Observou-se tendência crescente do desfecho no país no período pesquisado e queda na maioria das regiões, capitais e em todos os grupos de acordo com escolaridade. Houve uma queda da cobertura na maioria das regiões do Brasil. Destaca-se que o SII apresentou seus piores resultados em 2011 e 2012, alcançando 15,8p.p. (IC95%: 14,1; 17,6) e 15,0p.p. (IC95%: 13,1; 16,9), respectivamente, entre as mulheres com 12 anos ou mais de estudo. Houve queda na cobertura da realização do exame preventivo de câncer de colo de útero na maioria das regiões e capitais brasileiras entre os anos de 2011 e 2020. No período antes e durante a pandemia, houve redução do desfecho no país, nas regiões Sul e Sudeste, sugerindo que a pandemia de COVID-19 acarretou desigualdades geográficas na cobertura desse exame no país.

[PMID: 34166675 DOI: 10.1016/j.ypmed.2021.106692] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Revised: 05/19/2021] [Accepted: 06/17/2021] [Indexed: 12/13/2022]
Abstract
We conducted a systematic review of a wide range of contextual factors related to cancer screening uptake that have been studied so far. Studies were identified through PubMed and Web of Science databases. An operational definition of context was proposed, considering as contextual factors: social relations directly aimed at cancer screening, health care provider and facility characteristics, geographical/accessibility measures and aggregated measures at supra-individual level. We included 70 publications on breast, cervical and/or colorectal cancer screening from 42 countries, covering a data period of 24 years. A wide diversity of factors has been investigated in the literature so far. While several of them, as well as many interactions, were robustly associated with screening uptake (family, friends or provider recommendation, provider sex and experience, area-based socio-economic status…), others showed less consistency (ethnicity, urbanicity, travel time, healthcare density …). Screening inequities were not fully explained through adjustment for individual and contextual factors. Context, in its diversity, influences individual screening uptake and lots of contextual inequities in screening are commonly shared worldwide. However, there is a lack of frameworks, standards and definitions that are needed to better understand what context is, how it could modify individual behaviour and the ways of measuring and modifying it.

Breast and cervical cancer mortality in the western Amazon: A time series study between 1980 and 2014. Medicine (Baltimore) 2021; 100:e26157. [PMID: 34032773 PMCID: PMC8154483 DOI: 10.1097/md.0000000000026157] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/10/2020] [Revised: 04/28/2021] [Accepted: 05/10/2021] [Indexed: 01/04/2023] Open
Abstract
ABSTRACT Among the main types of neoplasms in the female population, breast and cervical cancers are the most important due to their high morbidity and mortality rates. The mortality has been proportionally higher in developing countries. Analysis of the trend of cancer mortality in Brazil revealed a considerable difference in the pattern of deaths between the regions.To analyze the trend of mortality due to breast and cervical cancers in women.Retrospective study of a series of death cases, using secondary data from the mortality information system (SIM) of the Ministry of Health. The deaths were identified as the underlying cause of breast and cervical cancers, including malignant neoplasms of the uterus without other specifications, occurring from 1980 to 2014. Thus, the annual standardized age-specific mortality rates by the world population were applied. For trend analysis, regression models were utilized in which the mortality rates were considered dependent variables and years the independent variable. Polynomial regression models and a Prais-Winsten regression model were adopted.Cervical cancer presented a mortality rate ranging from 2.15 to 10.69 per 100,000 women from 1980 to 2014, with a tendency for stability.Breast cancer mortality rate varied from 3.81 to 11.47 per 100,000 women from 1981 to 2014, indicating a growing trend.There is a significant increase in the mortality rate for breast cancer and stability of cervical cancers in the State of Acre from 1980 to 2014, evidencing a concern in their care and monitoring. Above all, guaranteed access, especially to the population of women at social risk, and the search for effective screening should be emphasized in the formation of the care line and the Health Care Network in the State of Acre.

Abstract
OBJECTIVE to assess the implementation of actions for early detection of breast cancer in Primary Care and to verify the adequacy of these actions with the Ministry of Health recommendations. METHOD a cross-sectional study conducted from September 2017 to March 2018 with 736 women registered in Basic Health Units in two municipalities in Acre. For data collection, a validated questionnaire was used. In statistical analysis, the chi-square test or Fisher's exact test was applied. RESULTS the frequency of mammography was 42%. Of the women at standard risk for breast cancer, only 5,8% underwent mammography properly. CONCLUSION there was a low compliance of early detection actions to the Ministry of Health recommendations; thus, the need to adopt measures to increase professionals' adherence to government proposals is highlighted, as well as continuous actions assessments.

Challenge of Incorporating New Drugs for Breast Cancer in Brazil: A Proposed Framework for Improving Access to Innovative Therapies. JCO Glob Oncol 2021; 7:474-485. [PMID: 33822641 PMCID: PMC8081546 DOI: 10.1200/go.20.00566] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2020] [Revised: 01/27/2021] [Accepted: 02/16/2021] [Indexed: 01/23/2023] Open
Abstract
PURPOSE The objective of this review is to address the barriers limiting access to treatment of advanced metastatic breast cancer (mBC) in Brazil, specifically for patients in the public health care system, arguably those with the least access to innovation. MATERIALS AND METHODS A selected panel of Brazilian experts in BC were provided with a series of relevant questions to address in a multiday conference. During the conference, responses were discussed and edited by the entire group through numerous drafts and rounds of discussion until a consensus was achieved. RESULTS The authors propose specific and realistic recommendations for implementing access to new drugs in cancer care in Brazil. Moreover, in creating these recommendations and framework, the authors strive to address the most important barriers and impediments for technology incorporation. A feasible and specific multidisciplinary process is proposed, which is based on the collective participation of all involved stakeholders. CONCLUSION Given the current benefits and likely future developments, there is a great need to expand treatments for mBC not only in Brazil but also in most other countries in the world where access issues remain an unresolved demand. Adapting the current framework is essential for accomplishing this goal. The recommendations in this review can serve as a framework for adoption of new technologies in countries with limited resources.

The Revised Champion's Health Belief Model Scale: Predictive Validity Among Brazilian Women. SAGE Open Nurs 2021; 6:2377960820940551. [PMID: 33415294 PMCID: PMC7774489 DOI: 10.1177/2377960820940551] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2020] [Revised: 05/26/2020] [Accepted: 06/13/2020] [Indexed: 11/25/2022] Open
Abstract
Mammography screening is provided free of charge for the recommended target
population in Brazil but participation rates have remained low, and breast
cancer mortality has continued to increase. Thus, it is important to
identify factors that are associated with poor participation in mammography
screening so that service providers can target health promotion messages and
screening programs more effectively. Objective: To evaluate the
predictive validity of the Revised Champion’s Health Belief Model scale
(RCHBMS) for identifying women at high risk of not adhering to national
guidelines for mammography screening in Brazil. Methods: We
used a longitudinal survey design with a 1-year follow-up data from 194
women living in northeastern Brazil, in the city of Fortaleza, Ceará,
participants completed the RCHBMS at baseline, and mammography uptake was
measured 1 year later. Hierarchical logistic regression was used to
determine the predictive validity of the RCHBMS for identifying women who
had not adhered to recommendations for mammography screening, after
accounting for the women’s sociodemographic and clinical characteristics.
The sensitivity and specificity of various cut-off points were calculated to
determine the optimal cut-off point for identifying women at high risk of
not adhering to mammography screening guidelines. Results: Two
subscales of the RCHBMS uniquely predicted nonadherence: susceptibility and
barriers, along with race and family history of cancer. The total scale
score (with barriers reverse coded) was also highly predictive. For our
sample, using only the RCHBMS with a cutoff of ≤ 3.67 (out of a total
possible range of 1–5) yielded a high sensitivity and specificity for
predicting nonadherence. Conclusion: Study findings support the
validity and clinical utility of the RCHBM for identifying women at risk of
not adhering to national guidelines for mammography screening in Brazil.

Abstract
Background Cervical cancer represents an important preventable cause of morbidity and mortality in developing countries such as Brazil. Investigating temporal evolution of a disease burden in the different realities of the country is essential for improving public policies. Objective To describe the national and subnational burden of cervical cancer, based on the estimates of the 2017 Global Burden of Disease study. Methods Descriptive study of premature mortality (years of life lost [YLL]) and burden of disease (disability-adjusted life years [DALYs]) associated with cervical cancer among Brazilian women aged 25-64 years, between 2000 and 2017. Findings During the study period, age-standardized incidence decreased from 23.53 (22.79-24.26) to 18.39 (17.63-19.17) per 100,000 women, while mortality rates decreased from 11.3 (11.05-11.56) to 7.74 (7.49-8.02) per 100,000 women. These rates were about two to three times greater than equivalent rates in a developed country, such as England: 11.98 (11.45-12.55) to 10.37 (9.85-10.9), and 3.75 (3.68-3.84) to 2.82 (2.75-2.9) per 100,000 women, respectively. Poorer regions of Brazil had greater rates of the disease; for instance, Amapá State in the Northern Region had rates twice as high as the national rates during the same period. Cervical cancer was the leading cause of premature cancer-related mortality (YLL = 100.69, 91.48-110.61 per 100,000 women) among young women (25-29 years) in Brazil and eight federation units of all country regions except the Southeast in 2017. There was a decrease in the burden of cervical cancer in Brazil from 339.59 (330.82-348.83) DALYs per 100,000 women in 2000 to 238.99 (230.45-247.99) DALYs per 100,000 women in 2017. Conclusion Although there has been a reduction in the burden of cervical cancer in Brazil, the rates remain high, mainly among young women. The persistence of inequalities between regions of Brazil suggests the importance of socioeconomic determinants in the burden for this cancer.

Abstract
We measured asset-based and education-based inequity in utilization of 2 cancer screening tests, Pap tests and mammograms, using nationally representative surveys conducted in 2003, 2008, and 2013. Utilization of Pap tests (ages 25-59 years) and mammograms (ages 50-69 years) increased over time. Asset-based and education-based inequities declined significantly for both screening tests, particularly among women who reported a doctor visit in the previous year. This decline coincided with increases in the coverage of primary health care in Brazil. However, barriers persisted; in 2013, college-educated women were still 2.27 times more likely to have a mammogram than those who were illiterate.

Analysis of the effects of the age-period-birth cohort on cervical cancer mortality in the Brazilian Northeast. PLoS One 2020; 15:e0226258.

Abstract
Cervical cancer (CC) is a public health problem with a high disease burden and mortality in developing countries. In Brazil, areas with low human development index have the highest incidence rates of Brazil and upward temporal trend for this disease. The Northeast region has the second highest incidence of cervical cancer (20.47 new cases / 100,000 women). In this region, the mortality rates are similar to rates in countries that do not have a health system with a universal access screening program, as in Brazil. Thus, this study aimed to analyze the effects of age, period and birth cohorts on mortality from cervical cancer in the Northeast region of Brazil. Estimable functions predicted the effects of age, period and birth cohort. The average mortality rate was 10.35 deaths per 100,000 women during the period analyzed (1980–2014). The highest mortality rate per 100,000 women was observed in Maranhão (24.39 deaths), and the lowest mortality rate was observed in Bahia (11.24 deaths). According to the period effects, only the state of Rio Grande do Norte showed a reduction in mortality risk in the five years of the 2000s. There was a reduction in mortality risk for birth cohorts of women after the 1950s, except in Maranhão State, which showed an increasing trend in mortality risk for younger generations. We found that the high rates of cervical cancer mortality in the states of northeastern Brazil remain constant over time. Even after an increase in access to health services in the 2000s, associated with increased access to the cancer care network, which includes early detection (Pap Test), cervical cancer treatment and palliative care. However, it is important to note that the decreased risk of death and the mortality rates from CC among women born after the 1960s may be correlated with increased screening coverage, as well as increased access to health services for cancer treatment observed in younger women.

Abstract
The study estimated parameters for planning and programming the supply of procedures for screening, diagnostic workup, and treatment of precursor lesions of uterine cervical cancer. These estimates were used as the basis for assessing the adequacy of Brazil's production of procedures performed by the Brazilian Unified National Health System (SUS) in 2017. Estimates were calculated using as the reference the recommended management in the national screening guidelines. Data on screening tests were obtained from the Information System on Uterine Cervical Cancer and the follow-up data from patient charts in a referral center for cervical pathology. Brazil's production of procedures was obtained from data in the Outpatient and Hospital Information Systems of the SUS. For every one hundred thousand women in the target age bracket for screening (25 to 64 years) there was an estimated annual need for 44,134 cytopathology tests, 1,886 colposcopies, 275 biopsies, 236 type 1 and 2 outpatient exicision procedures, 236 type 2 and 3 hospital exicision procedures, and 39 high-complexity referrals for surgery, chemotherapy, and/or radiotherapy. Applying the estimated parameters to the number of women screened in Brazil in 2017, a deficit was identified in all the procedures for adequate follow-up of the women with altered test results, varying from 7% in colposcopies to 74% in type 3 excisions. The results point to the need to expand and upgrade the supply of line of care procedures for cervical cancer. The estimated parameters can support policymakers in programming and implementing organized screening programs.

Abstract
Background: In Brazil, little is known regarding the underlying causes of differences among populations regarding socio-economic variables that affect women’s cervical cancer screening behavior. The present study focused on socio-economic variables that affect women’s performance of the Papanicolaou test, comparing two distinct Brazilian populations. Methods: We collected data regarding performance of the Papanicolaou test and socio-economic variables from 559 women in Mato Grosso do Sul (MS), in the Central East region, and 338 women in Paraíba (PB), in the Northeast region of Brazil. Nominal logistic regression modeling was performed to identify independent variables for both groups of data. Results: Of the women interviewed from MS and PB, 116 out of 599 (19.37%) and 94 out of 338 (27.81%), respectively, had not performed the Papanicolaou test within the last three years (p = 0.025). Low educational level characterized 570 (95.16%) and 203 (60.06%) of women from MS and PB, respectively (p = 0.000). Women in PB who had a low educational level and were unemployed had a 2.96-fold (OR = 0.338; 95% CI: 0.121 - 0.939) and 2.40-fold (OR = 0.416; 95% CI: 0.199 - 0.869) lower chance, respectively, to have performed the Papanicolaou test ≥ three times, or once within the last three years (p = 0.029; p = 0.014). The chance of women in MS who did not live in a stable relationship to have performed the test ≥ three times was 1.79-fold (OR = 0.560; 95% CI: 0.348 – 0.901) lower compared to women who reported a stable relationship (p = 0.039). Conclusions: High educational level, employment, and having a stable interpersonal relationship positively associated with performance of the Papanicolaou test among women in PB and MS. Despite having predominantly a low educational level, women in MS performed the Papanicolaou test more frequently than those in PB.

Abstract
Abstract: Our objectives with this study were to describe the spatial distribution of mammographic screening coverage across small geographical areas (micro-regions) in Brazil, and to analyze whether the observed differences were associated with spatial inequities in socioeconomic conditions, provision of health care, and healthcare services utilization. We performed an area-based ecological study on mammographic screening coverage in the period of 2010-2011 regarding socioeconomic and healthcare variables. The units of analysis were the 438 health micro-regions in Brazil. Spatial regression models were used to study these relationships. There was marked variability in mammographic coverage across micro-regions (median = 21.6%; interquartile range: 8.1%-37.9%). Multivariable analyses identified high household income inequality, low number of radiologists/100,000 inhabitants, low number of mammography machines/10,000 inhabitants, and low number of mammograms performed by each machine as independent correlates of poor mammographic coverage at the micro-region level. There was evidence of strong spatial dependence of these associations, with changes in one micro-region affecting neighboring micro-regions, and also of geographical heterogeneities. There were substantial inequities in access to mammographic screening across micro-regions in Brazil, in 2010-2011, with coverage being higher in those with smaller wealth inequities and better access to health care.

Abstract
OBJECTIVES To estimate and describe the coverage of the Pap Smear test reported by women aged 25 to 64 years old from data collected by the National Health Survey (Pesquisa Nacional de Saúde - PNS) and to compare the estimates made by the Surveillance System for Risk and Protective Factors for Chronic Diseases using a Telephone Survey (Vigitel) for the same indicator in the Brazilian capital cities and the Federal District in 2013. METHODS Based on the data from the PNS and Vigitel, we estimated prevalence and 95% confidence intervals (95%CI) of women who reported having had a Pap test screening in the past 3 years. RESULTS According to the PNS, 79.4% (95%CI 78.5 - 80.2) of the women had had a cervical cancer screening in the past 3 years in Brazil. Women aged 55 to 64 years old (71.0%, 95%CI 68.7 - 73.3) and without an education or incomplete elementary school (72.1%, 95%CI 70.6 - 73.7) had the lowest prevalence, and 88.4% (95%CI 87.5 - 89.2) received test results within 3 months. There was no difference when comparing the estimates of the Vigitel with the PNS for the capital city and Federal District totals. In the PNS, the prevalence was 83.8% (95%CI 82.8 - 84.7) and in the Vigitel, it was 82.9% (95%CI 81.9 - 83.8). In addition, there were no differences by capital, except for Recife, Boa Vista, and João Pessoa. CONCLUSION Cervical cancer screening coverage for the target population is below the target of 85%. When comparing the data for the capital city and Federal District totals, we verified that the Vigitel System has been effective in monitoring this indicator, which is similar to PNS estimates.

Breast and Cervical Cancer Screening Prevalence and Associated Factors among Women in the South African General
Population. Asian Pac J Cancer Prev 2018; 19:1465-1470. [PMID: 29936716 PMCID: PMC6103566 DOI: 10.22034/apjcp.2018.19.6.1465] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/02/2017] [Accepted: 10/09/2017] [Indexed: 02/07/2023] Open
Abstract
Purpose: The aims of the study were to estimate the prevalence of breast and cervical cancer screening among women in the South African general population and assess associated factors. Methods: Data from a national populationbased cross-sectional household survey in South Africa in 2012 for 10,831 women aged 30+ years were analysed using bivariate and multivariable logistic regression. The outcome variables were cervical cancer screening (Papanicolaou smear test) and breast cancer screening (mammography). Exposure variables were sociodemographic factors, lifestyle variables, and chronic conditions. Results: The prevalences of Papanicolaou (PAP) smear test and mammography participation were 52.0% and 13.4%, respectively. On multivariable logistic regression analysis, women with higher education, those who were non-black African, having medical aid and having chronic conditions were more likely to undergo a Pap smear test and mammography. Living in rural areas was related to a lower likelihood of receiving both types of screening. In addition, undertaking moderate or vigorous physical activity was associated with breast cancer screening. Conclusion: Screening for cervical cancer was relatively high but for breast cancer it was low, despite the latter being a major public health problem in South Africa. This may be attributed to the limited availability, affordability, and accessibility of breast cancer screening services among socio-economically disadvantaged individuals There are some socio-economic disparities in adopting both breast and cervical cancer screening guidelines that could be targeted by interventions.

Abstract
Objective: To analyze the mortality rates from malignant neoplasia in Brazil and Federal Units (FU) in the years 1990 and 2015, according to sex and main types of cancer. Methods: Using estimates of global disease burden for Brazil made by the GBD 2015 study, age-adjusted cancer mortality rates and respective 95% uncertainty intervals were calculated for Brazil and FU in 1990 and 2015, as well as their percentage variation in the period. The main causes of cancer mortality by sex were analyzed, considering the five highest rates in the country and for each state. Results: The cancer mortality rate for male and female population remained stable between the two years in the country. The same behavior pattern was observed in almost all the FU, and the majority of states in the northeast region and half of the north region showed a non-significant increase in mortality rates. Regarding the types of cancer, there was a drop in mortality rates for stomach cancers in both sexes (women: -38.9%, men: -37.3%), cervical cancer in women (-33.9%), and lung and esophagus cancer in men (-12.0% and -14.1%, respectively); in contrast, there was an increase in lung cancers in women (+20.7%) and colon and rectum cancers in men (+29.5%). Conclusion: Differences in the behavior of major cancers, with a decrease mainly in the more developed regions and an increase in the less developed regions of the country, seem to reflect the socioeconomic inequalities as well as difficulties in access to health services by the Brazilian population.
