Abstract
The scope of this study is to analyze the prevalence of advanced stage diagnosis of cervical cancer and its association with individual and contextual socioeconomic and healthcare service indicators in Brazil. A cross-sectional study was conducted using cervical cancer cases in women aged 18 to 99 years, from 2006 to 2015, extracted from the Hospital Cancer Registry (HCR) Integrator. Contextual variables were collected from the Atlas of Human Development in Brazil; the National Registry of Health Institutions (NRHI); and the Outpatient Information System. Multilevel Poisson Regression with random intercept was used. The prevalence of advanced stage diagnosis was 48.4%, revealing an association with older age groups (PR 1.06; CI 1.01-1.10), black, brown, and indigenous race/skin color (PR 1.04; CI 1.01-1.07), lower levels of schooling (PR 1.28; CI 1.16-1.40), no marital partner (PR 1.10; CI 1.07-1.13), public referral to the health service (PR 1.07; CI 1.03-1.11), and lower rates of cytological examination (PR 1.08; CI 1.01-1.14). The results reinforce the need for improvements in the national cervical cancer prevention program in areas with low coverage of oncotic cytology.

Lancet Glob Health 2024; 12:e292-e305. [PMID: 38245117 DOI: 10.1016/s2214-109x(23)00521-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2021] [Revised: 10/24/2023] [Accepted: 10/31/2023] [Indexed: 01/22/2024]
Abstract
BACKGROUND Breast cancer is a public health priority in Brazil and ensuring equity in health care is one of the cancer control plan goals. Our aim was to present the first assessment on the influence of race or skin colour on breast cancer survival at the national level. METHODS In this nationwide cohort study, data on women who initiated treatment for breast cancer in the public health-care system (Sistema Unico de Saúde), Brazil, were assembled through record linkage of administrative and mortality information systems. The administrative information systems were the Outpatient Information System (data from high complexity procedure authorisations) and the Hospital Information System (data from hospitalisation authorisations). We included women aged 19 years or older who started treatment between Jan 1, 2008, and Nov 30, 2010; self-identified as having White, Black, or Brown race or skin colour; had tumour stage I-IV; and were treated with chemotherapy or radiotherapy, or both. Patients were followed up until Dec 31, 2015. Patients with only hormone therapy records or who underwent only surgery were excluded. The Kaplan-Meier method was used to estimate crude overall survival for race or skin colour by time since treatment initiation, and Cox regression to estimate all-cause mortality hazard ratios (HRs) before and after adjustment for other covariates. FINDINGS We identified 59 811 women treated for stage I-IV breast cancer. 37 318 (62·4%) women identified themselves as White, 18 779 (31·4%) as Brown, and 3714 (6·2%) as Black. 5-year overall survival probability was higher for White women (74% [95% CI 73-74]) than Black women (64% [62-65]; p<0·0001). In adjusted regression models stratified by the absence of hormone therapy, Black women had a 24% (HR 1·24 [95% CI 1·16-1·34]; p<0·0001) higher risk of all-cause death than White women, and in the presence of hormone therapy Black women had a 25% (1·25 [1·14-1·38]; p<0·0001) higher risk of all-cause death than White women. INTERPRETATION Black skin colour was identified as a statistically significant risk marker for lower 5-year survival probability and higher risk of all-cause death among women treated for breast cancer by the Sistema Unico de Saúde. Actions to understand and mitigate this unfair difference in health results are urgently needed.

Cancer Epidemiol 2024; 88:102517. [PMID: 38141471 DOI: 10.1016/j.canep.2023.102517] [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: 08/03/2023] [Revised: 12/17/2023] [Accepted: 12/18/2023] [Indexed: 12/25/2023]
Abstract
OBJECTIVES To describe the epidemiological time trends and gender, age and regional differences of gastric cancer in Asia during 1990-2019, and to analyze the association between the human development index (HDI) and the statistical indicators of the burden of disease. METHODS Describing trends in age-standardized incidence rates (ASIR) and age-standardized mortality rate (ASMR) in Asia from 1990 to 2019 based on GBD-reported population-based surveillance of gastric cancer in Asia. Obtained ASIR, ASMR, and mortality to incidence ratios (MIR) for gastric cancer in different countries in 2019, with association analysis by Kruskal-Wallis nonparametric test. RESULTS The annual percentage change in ASIR and ASMR in Asia from 1990 to 2019 was - 1.20% and - 1.91%. Male gastric cancer patients have higher ASIR and ASMR than female gastric cancer patients. Decreasing trends in ASIR and ASMR for the total population in five Asian regions. From 1990 to 2019, the average annual change in ASMR was - 2.45%, - 1.43%, - 0.53%, - 0.62%, and - 0.27% for Central Asia, East Asia, high-income Asia-Pacific, South Asia, and Southeast Asia, respectively (p < 0.05). Both incidence and mortality were concentrated in the age groups of 85-89 and 89-94 years. Classifying Asian countries into different levels of HDI, only MIR was associated with HDI levels. CONCLUSION ASIR and ASMR of gastric cancer in the total population, different regions, and countries in Asia from 1990 to 2019 showed an overall decreasing trend. The MIR index is suggestive of survival rates and the role of cancer care in individual countries. Asian countries should develop different strategies for gastric cancer screening and prevention according to high-risk age, high-risk gender and HDI.

Socioeconomic and geographic disparities of breast cancer incidence according to stage at diagnosis in France. Cancer Causes Control 2024; 35:241-251.

Abstract
PURPOSE Low socioeconomic background (SB) has been associated with lower breast cancer (BC) incidence and higher BC mortality. One explanation of this paradox is the higher frequency of advanced BC observed in deprived women. However, it is still unclear if SB affects similarly BC incidence. This study investigated the link between SB and early/advanced BC incidence from Loire-Atlantique/Vendee Cancer registry data (France). MATERIALS AND METHODS Fourteen thousand three hundred fifty three women living in the geographic area covered by the registry and diagnosed with a primary BC in 2008-2015 were included. SB was approached by a combination of two ecological indexes (French European Deprivation Index and urban/rural residence place). Mixed effects logistic and Poisson regressions were used, respectively, to estimate the odds of advanced (stage ≥ II) BC and the ratio of incidence rates of early (stage 0-I) and advanced BC according to SB, overall and by age group (< 50, 50-74, ≥ 75). RESULTS Compared to women living in affluent-urban areas, women living in deprived-urban and deprived-rural areas had a higher proportion of advanced BC [respectively, OR = 1.11 (1.01-1.22), OR = 1.60 (1.25-2.06)] and lower overall (from - 6 to - 15%) and early (from - 9 to - 31%) BC incidences rates Advanced BC incidence rates were not influenced by SB. These patterns were similar in women under 75 years, especially in women living in deprived-rural areas. In the elderly, no association between SB and BC frequency/incidence rates by stage was found. CONCLUSION Although advanced BC was more frequent in women living in deprived and rural areas, SB did not influence advanced BC incidence. Therefore, differences observed in overall BC incidence according to SB were only due to higher incidence of early BC in affluent and urban areas. Future research should confirm these results in other French areas.

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.

Income Segregation, Conditional Cash Transfers, and Breast Cancer Mortality Among Women in Brazil. JAMA Netw Open 2024; 7:e2353100.

Abstract
Importance Women living in income-segregated areas are less likely to receive adequate breast cancer care and access community resources, which may heighten breast cancer mortality risk. Objective To investigate the association between income segregation and breast cancer mortality and whether this association is attenuated by receipt of the Bolsa Família program (BFP), the world's largest conditional cash-transfer program. Design, Setting, and Participants This cohort study was conducted using data from the 100 Million Brazilian Cohort, which were linked with nationwide mortality registries (2004-2015). Data were analyzed from December 2021 to June 2023. Study participants were women aged 18 to 100 years. Exposure Women's income segregation (high, medium, or low) at the municipality level was obtained using income data from the 2010 Brazilian census and assessed using dissimilarity index values in tertiles (low [0.01-0.25], medium [0.26-0.32], and high [0.33-0.73]). Main Outcomes and Measures The main outcome was breast cancer mortality. Mortality rate ratios (MRRs) for the association of segregation with breast cancer deaths were estimated using Poisson regression adjusted for age, race, education, municipality area size, population density, area of residence (rural or urban), and year of enrollment. Multiplicative interactions of segregation and BFP receipt (yes or no) in the association with mortality (2004-2015) were assessed. Results Data on 21 680 930 women (mean [SD] age, 36.1 [15.3] years) were analyzed. Breast cancer mortality was greater among women living in municipalities with high (adjusted MRR [aMRR], 1.18; 95% CI, 1.13-1.24) and medium (aMRR, 1.08; 95% CI, 1.03-1.12) compared with low segregation. Women who did not receive BFP had higher breast cancer mortality than BFP recipients (aMRR, 1.17; 95% CI, 1.12-1.22). By BFP strata, women who did not receive BFP and lived in municipalities with high income segregation had a 24% greater risk of death from breast cancer compared with those living in municipalities with low income segregation (aMRR, 1.24: 95% CI, 1.14-1.34); women who received BFP and were living in areas with high income segregation had a 13% higher risk of death from breast cancer compared with those living in municipalities with low income segregation (aMRR, 1.13; 95% CI, 1.07-1.19; P for interaction = .008). Stratified by the amount of time receiving the benefit, segregation (high vs low) was associated with an increase in mortality risk for women receiving BFP for less time but not for those receiving it for more time (<4 years: aMRR, 1.16; 95% CI, 1.07-1.27; 4-11 years: aMRR, 1.09; 95% CI, 1.00-1.17; P for interaction <.001). Conclusions and Relevance These findings suggest that place-based inequities in breast cancer mortality associated with income segregation may be mitigated with BFP receipt, possibly via improved income and access to preventive cancer care services among women, which may be associated with early detection and treatment and ultimately reduced mortality.

Abstract
OBJECTIVES There is limited evidence regarding the impact of race/racism and its intersection with socioeconomic status (SES) on breast and cervical cancer, the two most common female cancers globally. We investigated racial inequalities in breast and cervical cancer mortality and whether SES (education and household conditions) interacted with race/ethnicity. DESIGN The 100 Million Brazilian Cohort data were linked to the Brazilian Mortality Database, 2004-2015 (n = 20,665,005 adult women). We analysed the association between self-reported race/ethnicity (White/'Parda'(Brown)/Black/Asian/Indigenous) and cancer mortality using Poisson regression, adjusting for age, calendar year, education, household conditions and area of residence. Additive and multiplicative interactions were assessed. RESULTS Cervical cancer mortality rates were higher among Indigenous (adjusted Mortality rate ratio = 1.80, 95%CI 1.39-2.33), Asian (1.63, 1.20-2.22), 'Parda'(Brown) (1.27, 1.21-1.33) and Black (1.18, 1.09-1.28) women vs White women. Breast cancer mortality rates were higher among Black (1.10, 1.04-1.17) vs White women. Racial inequalities in cervical cancer mortality were larger among women of poor household conditions, and low education (P for multiplicative interaction <0.001, and 0.02, respectively). Compared to White women living in completely adequate (3-4) household conditions, the risk of cervical cancer mortality in Black women with 3-4, 1-2, and none adequate conditions was 1.10 (1.01-1.21), 1.48 (1.28-1.71), and 2.03 (1.56-2.63), respectively (Relative excess risk due to interaction-RERI = 0.78, 0.18-1.38). Among 'Parda'(Brown) women the risk was 1.18 (1.11-1.25), 1.68 (1.56-1.81), and 1.84 (1.63-2.08), respectively (RERI = 0.52, 0.16-0.87). Compared to high-educated White women, the risk in high-, middle- and low-educated Black women was 1.14 (0.83-1.55), 1.93 (1.57-2.38) and 2.75 (2.33-3.25), respectively (RERI = 0.36, -0.05-0.77). Among 'Parda'(Brown) women the risk was 1.09 (0.91-1.31), 1.99 (1.70-2.33) and 3.03 (2.61-3.52), respectively (RERI = 0.68, 0.48-0.88). No interactions were found for breast cancer. CONCLUSION Low SES magnified racial inequalities in cervical cancer mortality. The intersection between race/ethnicity, SES and gender needs to be addressed to reduce racial health inequalities.

Abstract
Interleukin-33 (IL-33), a member of the interleukin-1(IL-1) family of cytokines, remains poorly understood in the context of human breast cancer and its impact on treatment outcomes. This study aimed to elucidate IL-33 expression patterns within tumor samples from a cohort of Brazilian female breast cancer patients undergoing neoadjuvant chemotherapy while exploring its correlation with clinicopathological markers. In total, 68 samples were meticulously evaluated, with IL-33 expression quantified through a quantitative polymerase chain reaction. The findings revealed a substantial upregulation of IL-33 expression in breast cancer patient samples, specifically within the Triple-negative and Luminal A and B subtypes, when compared to controls (healthy breast tissues). Notably, the Luminal B subtype displayed a marked elevation in IL-33 expression relative to the Luminal A subtype (p < 0.05). Moreover, a progressive surge in IL-33 expression was discerned among Luminal subtype patients with TNM 4 staging criteria, further underscoring its significance (p < 0.005). Furthermore, chemotherapy-naïve patients of Luminal A and B subtypes exhibited heightened IL-33 expression (p < 0.05). Collectively, our findings propose that chemotherapy could potentially mitigate tumor aggressiveness by suppressing IL-33 expression in breast cancer, thus warranting consideration as a prognostic marker for gauging chemotherapy response and predicting disease progression in Luminal subtype patients. This study not only sheds light on the intricate roles of IL-33 in breast cancer but also offers valuable insights for future IL-33-related research endeavors within this context.

Abstract
OBJECTIVE This study aimed to evaluate the association between self-reported race/color and ancestry in Brazilian patients with breast cancer. METHODS This was an observational, transversal, epidemiological study, evaluating race and ancestry in 1,127 patients with breast cancer. For genetic ancestry, a 46-AIM-INDEL panel was used. The ancestral profile was evaluated with the Structure v.2.3.3 software. Descriptive statistics were performed. To assess differences between race and ancestry, an analysis of variance with Bonferoni adjustment was used. RESULTS The race distribution was 77.7% white, 17.6% brown, 4.1% black, 0.4% yellow, and 0.3% cafuse. The African ancestry proportion was significantly (p<0.001) more evident in black [0.63±0.21 (0.17-0.96)], followed by brown [0.25±0.16 (0.02-0.70)], and less frequent in white skin color. The European ancestry proportion was significantly (p<0.001) higher in white [0.72±0.17 (0.02-0.97)], followed by brown [0.57±0.19 (0.12-0.92)], yellow [0.27±0.31 (0.12-0.620], and black [0.24±0.19 (0.02-0.72)]. The Asiatic ancestry proportion is significantly (p<0.001) higher in yellow [0.48±0.51 (0.04-0.93)]. The Amerindian ancestry proportion frequency was the least frequent in all groups, and cafuse patients did not express differences between all race groups. The brown race group presented differences in African and European ancestry. CONCLUSION Although we found many similarities between white European ancestry, black African ancestry, and yellow Asian ancestry, there is great miscegenation between patients. Although they can be labeled as having one race, they do present many ancestral genes that would allow their inclusion in another race group.

Overall survival and associated factors in women with metastatic breast cancer treated with trastuzumab at a public referral institution. REVISTA BRASILEIRA DE EPIDEMIOLOGIA 2023; 26:e230045. [PMID: 37878833 PMCID: PMC10642446 DOI: 10.1590/1980-549720230045] [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: 11/07/2022] [Revised: 07/18/2023] [Accepted: 07/20/2023] [Indexed: 10/27/2023] Open
Abstract
OBJECTIVE To characterize associated factors and overall survival of women with metastatic breast cancer treated with trastuzumab after its incorporation into the SUS, and additionally to present the direct costs of this technology. METHODS This is a retrospective cohort, based on data from computerized medical records from one of the units of the National Cancer Institute (INCA), in Rio de Janeiro-RJ, Brazil. Women with HER-2 positive metastatic breast cancer undergoing trastuzumab treatment from September 2017 to August 2018 were included. Overall survival was estimated using the Kaplan-Meier method and compared between groups using the log-rank test. RESULTS 136 women were selected, whose median age at diagnosis was 51 years (range: 21-81 years). The median OS was 43.63 months (95%CI 33.92-53.34). It is observed that the median OS for the population already diagnosed with metastatic disease (stage IV) was significantly lower than for patients diagnosed in stages I-III (37.43 months vs. 48.6 months, p<0, 01). Women without previous use of trastuzumab had a higher median OS than patients pretreated with trastuzumab (45.16 months vs. 40.73 months, p<0.01). CONCLUSION Trastuzumab improves survival in HER-2 positive metastatic breast cancer. Brain and multiple metastases are associated with a worse prognosis. It is essential to avoid advanced staging and perform surgical treatment, with emphasis on radical mastectomy. The SUS must adopt policies and strategies for early diagnosis and guarantee access to trastuzumab, considering its high cost.

Abstract
PURPOSE Breast cancer molecular subtypes show significant differences in different ethnic groups in the United States, but no study has evaluated genetic ancestry in breast cancer in Brazilian women. METHODS Breast cancer patients from distinct parts of Brazil were evaluated. Molecular subtypes were determined by immunohistochemistry. Genetic ancestry was evaluated using a panel of 46 AIMs (ancestry informative markers), which classified genetic ancestry as European, African, Asian, and Amerindian. PCR products were subjected to capillary electrophoresis and analyzed using GeneMapper 4.0 software. Ancestry was evaluated with Structure v.2.3.3 software. Ancestry was tested for correlations with geographic region and molecular subtype. The chi-square test and ANOVA with Bonferroni adjustment were applied. RESULTS Genetic ancestry and clinical data were evaluated in 1127 patients. Higher rates of self-reported white ethnicity, European ancestry, and HER-2- luminal tumors were identified in the South region, which may influence age at diagnosis and result in a higher rate of early tumors. Conversely, higher rates of African ancestry in the North and Northeast regions, self-reported nonwhite ethnicity, HER-2+ tumors, and triple-negative tumors were noted. Triple-negative and HER-2+ tumors were associated with higher advanced and metastatic disease rates at diagnosis, with triple-negative tumors being more frequent in young women. CONCLUSION Differences in genetic ancestry, self-reported ethnicity, and molecular subtype were found between Brazilian demographic regions. Knowledge of these features may contribute to a better understanding of age at diagnosis and the molecular distribution of breast cancer in Brazil.

Abstract
OBJECTIVES To analyze the rates of breast cancer survival among Black and White women according to age and stage at diagnosis. STUDY DESIGN A retrospective cohort study. METHODS The study examined women registered in the population-based cancer registry of Campinas in 2010-2014. The primary variable was the declared race (White or Black). Other races were excluded. Data were linked with the Mortality Information System, and missing information was accessed by active search. Overall survival (OS) was calculated by the Kaplan-Meier method, comparisons were done by chi-squared tests, and hazard ratios were examined by Cox regression. RESULTS The total numbers of new cases of staged breast cancer among Black and White women were 218 and 1522 cases, respectively. The rates of stages III/IV were 35.5% among White women and 43.1% among Black women (P = 0.024). The frequencies among White and Black women under 40 years old were 8.0% and 12.4% (P = 0.031), 19.6% and 26.6% (P = 0.016) for ages of 40-49 years, and 23.8% and 17.4% (P = 0.037) for ages of 60-69 years, respectively. The mean OS was 7.5 years (7.0; 8.0) among Black women and 8.4 years (8.2; 8.5) among White women. The 5-year OS was 72.3% among Black women and 80.5% among White women (P = 0.001). Black women had an age-adjusted risk of death that was 1.7 times higher (1.33; 2.20). The risk was 6.4 times higher for diagnoses in stage 0 (1.65; 24.90) and 1.5 times for diagnoses in stage IV (1.04; 2.17). CONCLUSION The 5-year OS for women with breast cancer was significantly lower among Black women than White women. Black women were more frequently diagnosed in stages III/IV, and their age-adjusted risk of death was 1.7 times higher. Differences in access to care may explain these differences.

Abstract
Background The aim of this study was to report the overall survival and baseline factors associated with OS for breast, cervical and ovarian cancer in Florianópolis, Southern Brazil, a region with quality-of-life indicators comparable to high-income countries. Methods Cohort study was performed from probabilistic record linkage of the Mortality Information System and the Population-based cancer registry of Florianópolis. It was included breasts, cervical and ovarian cancer diagnosis during the period of 2008-2012 with a follow up of 60 months. Cox regression and Kaplan-Meier method were used for associations with overall survival and risk factors. Findings 1857 cases of the three malignancies were included in the analysis. We identified 202 deaths in breast cancer subjects, 53 for cervical cancer and 51 for ovarian cancer. Metastatic disease at diagnosis was present in 31%, 9.6%, and 55% of the cases, respectively. Overall survival was statistically correlated with age, educational level and stage for breast cancer; age and stage for cervical cancer; age and stage for ovarian cancer. Interpretation Metastatic disease and age are the main prognostic factors for the malignancies studied, as they were associated with both overall survival and risk of death. Better screening and preventive tests for early diagnosis are needed.

Abstract
BACKGROUND In several countries, such as Brazil, the oncological diagnosis usually occurs at an advanced stage of the disease. Thus, the aim of this study was to investigate temporal trends and factors associated with the cancer diagnosed at stage IV in Brazil in two decades. METHODS Secondary-based study, with time series analysis for trend assessment and cross-sectional of factors associated with diagnosis of female breast, prostate, cervix uteri, colorectal, lung, stomach, lip and oral cavity, thyroid, esophagus or corpus uteri at stage IV. RESULTS 1,218,322 cases were evaluated. The types of cancer with the highest proportion of stage IV at diagnosis in men and women, respectively, were: lung (53.7% and 57.4%), stomach (48.4% and 45.0%) and lip/oral cavity (53.5% and 43.4%). Most showed an increasing trend of annual percent change of cancer diagnosed at stage IV, being more pronounced in corpus uteri cancer (2013-2019: +7.4%, p < 0.001). The odds of cancer diagnosed at stage IV were associated with different factors, according to primary tumor site, but marked by the inverse association with female sex [odds ratio (OR) ranging from 0.42 to 0.91, p < 0.001] and direct association in cases with < 7 years of study (OR ranging from 1.08 to 1.81, p < 0.001), living without a partner (OR ranging from 1.06, p < 0.050 to1.27, p < 0.001), living in the South and Southeast regions (OR ranging from 1.04 to 1.13, p < 0.001), with more than one tumor (OR ranging from 1.19, p < 0.050 to 1.54, p < 0.001) and treated in Centers of High Complexity in Oncology (OR ranging from 1.03, p < 0.050 to1.24, p < 0.001). CONCLUSION There was a high frequency of cancer diagnosed at stage IV and an increasing trend in different cancer types, which were associated with distinct sociodemographic, lifestyle, and clinical factors.

An experience of a single-center study effect of surgery delay in survival. Surg Oncol 2022; 44:101854. [PMID: 36122450 DOI: 10.1016/j.suronc.2022.101854] [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: 03/14/2022] [Revised: 08/22/2022] [Accepted: 09/09/2022] [Indexed: 11/17/2022]
Abstract
BACKGROUND AND OBJECTIVES Proper treatment is critical for control and curative intent in breast cancer. Delays in receiving treatment can influence patients' prognoses. METHODS Retrospective, observational, single-center study based on data from medical records of 747 patients with non-metastatic invasive ductal breast carcinoma (I-III) in the initial analysis, comprising 554 patients undergoing adjuvant and 193 neoadjuvant treatment. Kaplan-Meier, Cox regression and time-dependent Cox regression were performed to obtain the predictive value of time to surgery and time to first treatment. Immortal time bias was managed and only 721 patients were included in the multivariable analysis. RESULTS During a median observation of 64.4 months, there were 140 death events and 177 disease progression events. Time to surgery (TTS) and time from completion of neoadjuvant chemotherapy to surgery (TNS) showed a significant impact on overall survival, associated with a 6% increased chance of death [HR: 1.06 (1.03-1.09), p < 0.001] and 4% [HR: 1.04 (1.00-1.09), p = 0.048] with a one-month increment, respectively. By multivariable analysis, continuous TTS had a different weight as a prognostic factor in stage IIIA/IIIB [adjusted HR: 1.249 (1.072-1.454), p = 0.004] compared to stage I/II [adjusted HR: 1.093 (1.048-1.141), p < 0.0005]. Likewise, TNS was significant after adjusting for other factors [adjusted HR: 1.092 (1.038-1.148), p = 0.001]. CONCLUSION Delay in receiving surgery with curative intent impairs the survival of patients with breast cancer.

Abstract
OBJECTIVE We aim to report the incidence, mortality and disability-adjusted life years (DALYs) between 1990 and 2019 and provide predictions to 2035. METHODS We use estimates from Global Burden of Disease, Injuries and Risk Factors Study 2019 to analyse the incidence, mortality and DALYs. RESULTS In 2019, there were more than 209,149 incidence cases, with age-standardised rates (ASRs) of 2.5. Laryngeal cancer accounted for 123,356 death cases, with ASRs of 1.5. Laryngeal cancer was also responsible for 3.26 million (3,034,634 to 3,511,354) DALYs, with ASRs of 38.8 (36.1 to 41.8). In 2019, Central Europe had the highest age-standardised incidence rate. At the national level, the highest incidence rate was observed in Mongolia. Total number and rate were significantly higher among males than females across all age groups. DALYs were attributable to Alcohol use, Smoking, Occupational exposure to sulfuric acid and asbestos. The age-standardised incidence rates in seven GBD regions and 59 countries are projected to increase between 2019 and 2035. CONCLUSIONS Despite the current and predicted decline in age-standardised incidence globally, the absolute number of estimates continue to increase. Prevention programmes should concentrate on modifiable risk factors, especially among the males across all age groups.

Abstract
OBJECTIVE To analyze the time to diagnosis and treatment for breast cancer and the associated factors, according to the type of care (public vs. private). METHODOLOGY Retrospective cohort study with 477 women diagnosed with breast cancer between 2014 and 2016. Data were collected in an oncology service in a municipality in Minas Gerais, in the 2018-2019 period. Analyzes were performed using the Kaplan-Meier method and Cox's proportional regression model. RESULTS The median time to diagnosis was 70 days, being shorter for women who discovered the disease through screening tests and who were diagnosed in early stages of the disease. The median time for treatment was 32 days, which was shorter for women assisted by private health service, with a high level of education and who were diagnosed in early stages. CONCLUSIONS Private care and facilitators of access to breast cancer care were associated with shorter waiting times.

Abstract
We describe the characteristics of cases of breast cancer among women assisted at hospitals affiliated to the public health system in the state of São Paulo (Brazil), analysing the effects of level of education and travel burden to point of treatment. We conducted a retrospective analysis of invasive breast cancer among women diagnosed between 2000 and 2015. Data were extracted from the hospital-based cancer registries of Fundação Oncocentro de São Paulo—FOSP. The outcome was clinical stage at diagnosis (stage III–IV versus I–II). The explanatory variables were educational level and travel burden. Odds ratios (OR) and 95% confidence intervals (95% CI) were estimated. Multiple imputations were used for missing educational level (31%). The study included 81,669 women with invasive breast cancer diagnosed between 2000 and 2015. The mean age of patients at diagnosis was 56.8 years (standard deviation 13.6 years). 38% of patients were at an advanced stage at diagnosis (stage III–IV). Women with lower levels of education and those who received cancer care in municipalities other than where they lived were more likely to be diagnosed at an advanced stage. In conclusion, promotion of breast cancer awareness and improving pathways to expedite breast cancer diagnosis and treatment could help identify breast tumors at earlier stages.

Abstract
The high incidence and mortality rates make lung cancer a global public health issue. Socioeconomic conditions and the provision of health services may be associated with this reality. This study investigates the spatial distribution of advanced-stage diagnosis and mortality due to lung cancer and its association with the healthcare services supply and demographic and socioeconomic indicators in Brazil. This is an ecological study with 161 Intermediate Regions of Urban Articulation. Mortality data were extracted from the Mortality Information System, and the cases of lung cancer were obtained from the Integrator of Hospital-Based Cancer Registries from 2011 to 2015. Analyses employed Moran’s I, local indicators of spatial association, and the multivariable model. The proportion of advanced-stage diagnosis was 85.28% (95% CI 83.31–87.10) and was positively associated with the aging rate (Moran’s I 0.11; p = 0.02), per capita income (Moran’s I 0.05; p = 0.01) and negatively associated with Gini Index (Moran’s I -0.16; p = 0.01). The mean age-adjusted mortality rates was 12.82 deaths/100,000 inhabitants (SD 5.12). The age-adjusted mortality rates for lung cancer presented a positive and statistically significant spatial association with all demographic, socioeconomic and healthcare services supply indicators, except for the "density of family health teams" (Moran’s I -0.02 p = 0.28). The multivariable model for the mortality rates was constituted by the variables “Density of facilities licensed in oncology”, “Per capita income”, and “Health plan coverage”. The per capita income presented positive association and health plan coverage negative association with age-adjusted mortality rates. Both associations were statistically significant. The variable density of facilities licensed in oncology showed no significant association with age-adjusted mortality rates. There is a high proportion of advanced-stage diagnosis across the Brazilian territory and inequalities in lung cancer mortality, which are correlated with the most developed areas of the country.

Abstract
We aim to report the latest incidence, mortality, and disability-adjusted life-years (DALYs) between 1990 and 2019, by age, sex, sociodemographic index (SDI), and provide predictions to 2035. We use estimates from Global Burden of Disease, Injuries, and Risk Factors Study 2019 to analyze the incidence, mortality, and DALYs. All the estimates were shown as counts and age-standardized rates (ASR). In 2019, there were more than 176,501 (156,046 to 199,917) incidence cases, with ASRs of 2.1 (1.9 to 2.4). Nasopharyngeal cancer (NPC) accounted for 71,610 (65,442 to 77,625) deaths, with ASRs of 0.9 (0.8 to 0.9). NPC was also responsible for 2.34 million (2,139,753 to 2,536,657) DALYs, with ASRs of 28.0 (25.7 to 30.4). The count of all the new cases increased from 1990 to 2019. At the regional level, the highest age-standardized incidence rates were found in East Asia, the highest age-standardized death and DALY rates were shown in Southeast Asia. At the national level, the age-standardized incidence rates were highest in Singapore, and the age-standardized death and DALY rates were highest in Malaysia. The total numbers and rates of all the estimates were significantly higher among males than females across most of the age groups. The considerable burden of NPC was attributable to alcohol use, smoking, and occupational exposure to formaldehyde. A total of six GBD regions and 88 countries are projected to experience an increase in NPC ASRs between 2019 and 2035, respectively. Despite the current decline in age-standardized mortality and DALY rates globally, the age-standardized incidence rate has increased from 1990 to 2019, and continues to increase between 2020 and 2035, indicating that nasopharyngeal cancer remains a major health challenge worldwide. Prevention strategies should focus on modifiable risk factors, especially among males in East Asia.

Abstract
OBJECTIVE The study aimed to characterize the clinical, histological, and immunohistochemical profile of women with invasive breast cancer, according to the risk for Hereditary Predisposition Breast and Ovarian Cancer Syndrome in a Brazilian population. METHODS This is a retrospective study performed from a hospital-based cohort of 522 women, diagnosed with breast cancer treated at an oncology referral center in the Southeast region of Brazil, between 2014 and 2016. RESULTS Among the 430 women diagnosed with invasive breast cancer who composed the study population, 127 (29.5%) were classified as at increased risk for hereditary predisposition to breast and ovarian cancer syndrome. There was a lower level of education in patients at increased risk (34.6%) when compared with those at usual risk (46.0%). Regarding tumor characteristics, women at increased risk had higher percentages of the disease diagnosed at an advanced stage (32.3%), and with tumors > 2cm (63.0%), with increased prevalence for both characteristics, when compared with those at usual risk. Furthermore, we found higher percentages of HG3 (43.3%) and Ki-67 ≥ 25% (64.6%) in women at increased risk, with prevalence being about twice as high in this group. The presence of triple-negative tumors was observed as 25.2% in women at increased risk and 6.0% in women at usual risk, with the prevalence of absence of biomarkers being 2.5 times higher among women in the increased risk group. CONCLUSION From the clinical criteria routinely used in the diagnosis of breast cancer, the care practice of genetic counseling for patients at increased risk of hereditary breast cancer in contexts such as Brazil is still scarce.

Abstract
Resumo Este estudo transversal investigou a prevalência e os fatores associados ao diagnóstico de câncer de mama em estágio avançado entre 18.890 mulheres assistidas em hospital especializado da capital do Rio de Janeiro, Brasil, entre os anos 1999 e 2016. Utilizou-se regressão de Poisson com variância robusta para estimar razões de prevalência e respectivos intervalos de 95% de confiança. Apresentaram maiores prevalências de diagnóstico nessa condição mulheres com idade entre 20-39 e 40-49 anos, de raça/cor da pele preta e parda, que viviam sem companheiro(a), procedentes de outros municípios do estado do Rio de Janeiro, que tiveram o Sistema Único de Saúde como origem do encaminhamento e que foram diagnosticadas nos sexênios 1999-2004 e 2005-2010. Em contrapartida, mulheres com idade entre 60-69 e 70-99 anos, que cursaram algum nível de escolaridade, com histórico familiar de câncer e que chegaram ao hospital com diagnóstico e sem tratamento apresentaram menores prevalências de diagnóstico em estágio avançado. Esses resultados podem ser considerados no planejamento de ações de prevenção secundária, a fim de antecipar o diagnóstico de câncer de mama dos grupos mais vulneráveis e assim colaborar para a redução da prevalência do diagnóstico em estágio avançado.

Abstract
OBJECTIVE To study the impact of socio-economic status and ethno-racial strata on excess mortality hazard and net survival of women with breast cancer in two Brazilian state capitals. METHOD We conducted a survival analysis with individual data from population-based cancer registries including women with breast cancer diagnosed between 1996 and 2012 in Aracaju and Curitiba. The main outcomes were the excess mortality hazard (EMH) and net survival. The associations of age, year of diagnosis, disease stage, race/skin colour and socioeconomic status (SES) with the excess mortality hazard and net survival were analysed using multi-level spline regression models, modelled as cubic splines with knots at 1 and 5 years of follow-up. RESULTS A total of 2045 women in Aracaju and 7872 in Curitiba were included in the analyses. The EMH was higher for women with lower SES and for black and brown women in both municipalities. The greatest difference in excess mortality was seen between the most deprived women and the most affluent women in Curitiba, hazard ratio (HR) 1.93 (95%CI 1.63-2.28). For race/skin colour, the greatest ratio was found in Curitiba (HR 1.35, 95%CI 1.09-1.66) for black women compared with white women. The most important socio-economic difference in net survival was seen in Aracaju. Age-standardised net survival at five years was 55.7% for the most deprived women and 67.2% for the most affluent. Net survival at eight years was 48.3% and 61.0%, respectively. Net survival in Curitiba was higher than in Aracaju in all SES groups." CONCLUSION Our findings suggest the presence of contrasting breast cancer survival expectancy in Aracaju and Curitiba, highlighting regional inequalities in access to health care. Lower survival among brown and black women, and those in lower SES groups indicates that early detection, early diagnosis and timely access to treatment must be prioritized to reduce inequalities in outcome among Brazilian women.

Abstract
Cancer incidence is rising in low- and especially middle-income countries (MIC), driven primarily by four high-burden cancers (breast, cervix, lung, colorectal). By 2030, more than two-thirds of all cancer deaths will occur in MICs. Prevention and early detection are required alongside efforts to improve access to cancer treatment. Successful strategies for decreasing cancer mortality in high-income countries are not always effective, feasible or affordable in other countries. In this review, we evaluate strategies for prevention and early detection of breast, cervix, lung, and colorectal cancers, focusing on modifiable risk factors and high-risk subpopulations. Tobacco taxation, human papilloma virus vaccination, cervical cancer screen-and-treat strategies, and efforts to reduce patient and health system-related delays in the early detection of breast and colorectal cancer represent the highest yield strategies for advancing cancer control in many MICs. An initial focus on high-risk populations is appropriate, with increasing population coverage as resources allow. These strategies can deliver significant cancer mortality gains, and serve as a foundation from which countries can develop comprehensive cancer control programs. Investment in national cancer surveillance infrastructure is needed; the absence of national cancer data to identify at-risk groups remains a barrier to the development of context-specific cancer control strategies.

Abstract
Obesity has been associated with an increased risk of breast cancer recurrence and death. Some readily available biomarkers associated with systemic inflammation have been receiving attention as potential prognostic indicators in cancer, including neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR). This study aimed to explore the correlation between body mass index (BMI) and invasive breast cancer and the association of NLR, PLR, and BMI with breast cancer outcomes. We undertook a retrospective study to evaluate patients treated for breast cancer over 14 years. Clinicopathological data was obtained before receiving any treatment. Of the 1664 patients included with stage I-III, 567 (34%) were obese (BMI≥30 kg/m2). Obese patients had larger tumors compared to non-obese patients. Higher BMI was associated with recurrence and worse survival only in patients with stage I disease. NLR and PLR were classified into high and low level groups. The NLRhigh (NLR>4) was found to be an independent prognostic factor for recurrence and mortality, while the PLRhigh (PLR>150) group had no impact on survival. A subgroup of patients with NLRhigh and BMIhigh had the worst disease-free survival (P=0.046), breast cancer-specific survival (P<0.001), and overall survival (P=0.006), compared to the other groups. Patients with early-stage breast cancer bearing NLRhigh and BMIhigh had worse outcomes, and this might be explained by the dysfunctional milieu of obesity in adipose tissue and its effects on the immune system. This study highlights the importance of lifestyle measures and the immune system interference with clinical outcomes in the early breast cancer setting.

Abstract
Patients in Brazil continue to present with late-stage breast cancer. Notwithstanding these figures, policies and programs to overcome this long-lasting scenario have had limited results. We enlist the main barriers for advancing breast cancer diagnosis in Brazil, based on the available evidence, and we propose feasible strategies that may serve as a platform to address this major public health challenge.

Abstract
PURPOSE The implementation of national breast cancer (BC) screening programs in Latin America has been rather inconsistent. Instead, most countries have opted for "opportunistic" mammogram screenings on the population at risk. Our study assessed and compared epidemiological, clinical factors, and survival rates associated with BC detected by screening (SDBC) or self-detected/symptomatic (non-SDBC) in Chilean female patients. METHODS Registry-based cohort study that included non-metastatic BC (stage I/II/III) patients diagnosed between 1993 and 2020, from a public hospital (PH) and a private university cancer center (PC). Epidemiological and clinical data were obtained from medical records. RESULTS A total of 4559 patients were included. Most patients (55%; n = 2507) came from PH and were diagnosed by signs/symptoms (non-SDBC; n = 3132, 68.6%); these patients displayed poorer overall (OS) and invasive disease-free survival (iDFS) compared to SDBC. Importantly, the proportion of stage I and "luminal" BC (HR + /HER2 -) were significantly higher in SDBC vs. non-SDBC. Finally, using a stage/subset-stratified age/insurance-adjusted model, we found that non-SDBC cases are at a higher risk of death (HR:1.75; p < 0.001). In contrast, patients with PC health insurance have a lower risk of death (HR: 0.60; p < 0.001). CONCLUSION We confirm previous studies that report better prognosis/survival on SDBC patients. This is probably due to a higher proportion of stage I and luminal-A cases versus non-SDBC. In turn, the survival benefit observed in patients with PC health insurance might be attributed to a larger proportion of SDBC. Our data support the implementation of a systematic BC screening program in Chile to improve patient prognosis and survival rates.

Gynecol Oncol 2021; 162:778-787. [PMID: 34140180 DOI: 10.1016/j.ygyno.2021.06.008] [Citation(s) in RCA: 18] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/26/2021] [Accepted: 06/08/2021] [Indexed: 12/24/2022]
Abstract
The aim of this meta-analysis is to evaluate the effect of marital status on the stage at diagnosis and survival of female patients with breast and gynecologic cancers. A systematic literature search was conducted on electronic databases (PubMed, Cochrane and EMBASE) till December 31, 2020. Publications investigating the association of marital status with stage at diagnosis and/or cancer-specific mortality (CSM) and/or overall survival (OS) in female patients with breast or gynecologic cancers were retrieved. After studies were selected according to inclusion criteria, data extraction, quality assessment and data analysis were performed. 55 articles were eligible for inclusion, consisting of 1,195,773 female cancer patients with breast, vulvar, cervical, endometrial and ovarian cancers. Unmarried female cancer patients had higher odds of being diagnosed at later stage [odds ratio (OR) = 1.28, 95% confidence interval (CI): 1.22-1.36)] and worse survival outcomes in CSM [hazard ratio (HR) = 1.22, 95% CI: 1.16-1.28] and OS (HR = 1.20, 95% CI: 1.14-1.25). This estimate did not vary by level of social support, number of adjustment factors, or between America and Europe. Being married is associated with timely diagnosis and favorable prognosis in most women's cancers. Unmarried female cancer patients have a higher risk of late-stage diagnosis and worse survival outcomes than the married. Greater concern shall be demonstrated towards unmarried female cancer patients. Furthermore, the impact of lacking economic and emotional support on survival outcomes in unmarried female cancer patients deserves particular attention.

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.

Abstract
Breast cancer presents high incidence and mortality rates, being considered an important public health issue. Analyze the spatial distribution pattern of late stage diagnosis and mortality for breast cancer and its correlation with socioeconomic and health service offer-related population indicators. Ecological study, developed with 161 Intermediate Region of Urban Articulation (IRUA). Mortality data were collected from the Mortality Information System (MIS). Tumor staging data were extracted from the Hospital Cancer Registry (HCR). Socioeconomic variables were obtained from the Atlas of Human Development in Brazil; data on medical density and health services were collected from the National Registry of Health Institutions (NRHI) and Supplementary National Health Agency. Global Moran's Index and Local Indicator of Spatial Association (LISA) were utilized to verify the existence of territorial clusters. Multivariate analysis used models with global spatial effects. The proportion of late stage diagnosis of breast cancer was 39.7% (IC 39.4–40.0). The mean mortality rate for breast cancer, adjusted by the standard world population was 10.65 per 100,000 women (± 3.12). The proportion of late stage diagnosis presented positive spatial correlation with Gini’s Index (p = 0.001) and negative with the density of gynecologist doctors (p = 0.009). The adjusted mortality rates presented a positive spatial correlation with the Human Development Index (p<0.001) and density of gynecologist doctors (p<0.001). Socioeconomic and health service offer-related inequalities of the Brazilian territory are determinants of the spatial pattern of breast cancer morbimortality in Brazil.

Abstract
The advanced-stage diagnosis of breast cancer reveals the inequalities associated with socioeconomic conditions and the offer of health services. This study analyzes the prevalence of advanced breast cancer and its relationship with individual and contextual socioeconomic indicators and offer of health service. A cross-sectional study is presented herein, on the assessment of malignant breast neoplasms in women diagnosed between 2006 and 2015 (n = 195,201). Data were collected from the Hospital Cancer Registry (HCR), Atlas of Human Development in Brazil, and from the National Registry of Health Institutions (NRHI). A multilevel Poisson Regression was carried out with random intercept. The prevalence of advanced breast cancer diagnosis was 40.0%. Advanced staging was associated with younger age groups (PR 1.41), race/nonwhite (PR 1.13), lower education levels (PR 1.38), and public access to health services (PR 1.25). There was also an association with a low density of mammographic equipment (PR 1.08), and with low indices of local social inequality (PR 1.33) and human development (PR 0.80). This study maps and highlights the causes related to inequalities in the diagnosis of advanced breast cancer in Brazil, and presents essential data to reorient public policies and health-related actions to strengthen the control of breast cancer in Brazil.

Abstract
PURPOSE This study aims to examine the burden of breast cancer in 185 countries in 2018. METHODS The estimates of incidence, mortality, and prevalence of breast cancer were drawn from GLOBOCAN 2018. The overall burden of breast cancer was gauged using breast cancer burden index (BRCBI)-a novel index comprising age-standardized incidence rate (ASIR), age-standardized mortality rate (ASMR), mortality-to-incidence ratio (MIR), prevalence-to-incidence ratio (PIR), and prevalence-to-mortality ratio (PMR). The socioeconomic status of countries was measured using human development index (HDI) RESULTS: Globally, breast cancer was responsible for an estimated 626,679 deaths at age-standardized rate of 13/100,000; there were 2.1 million cases diagnosed in 2018 at age-standardized rate of 46.3/100,000. The ASIR varied 22-fold from 5/100,000 (Bhutan) to 113.2/100,000 (Belgium). The ASMR varied 13-fold from 2.7/100,000 (Bhutan) to 36.9/100,000 (Fiji). The HDI exhibited a positive gradient with ASIR (r = 0.73), PIR (r = 0.98), and PMR (r = 0.85); with MIR, however, it exhibited a negative association (r = - 0.83). The BRCBI spanned from 0.70 in Somalia to 78.92 in South Korea and exhibited a positive association with HDI (r = 0.76). An additional 46,823 female lives in 2018 and a cumulative total of 333,304 lives could have been saved over 2013-2018, had countries performed as per their HDI. CONCLUSIONS The substantial burden of breast cancer in developing and low-resource economies calls for a holistic approach to cancer management and control that includes oncologic infrastructure to provide cost-effective screening, diagnostic, therapeutic, and palliative services, greater breast cancer awareness, and mitigation of risk factors.

Abstract
Most breast cancer patients in sub-Saharan Africa are diagnosed at advanced stages after prolonged symptomatic periods. In the multicountry African Breast Cancer-Disparities in Outcomes cohort, we dissected the diagnostic journey to inform downstaging interventions. At hospital presentation for breast cancer, women recalled their diagnostic journey, including dates of first noticing symptoms and health-care provider (HCP) visits. Negative binomial regression models were used to identify correlates of the length of the diagnostic journey. Among 1429 women, the median (inter-quartile range) length (months) of the diagnostic journey ranged from 11.3 (5.7-21.2) in Ugandan, 8.2 (3.4-16.4) in Zambian, 6.5 (2.4-15.7) in Namibian-black to 5.6 (2.3-13.1) in Nigerian and 2.4 (0.6-5.5) in Namibian-non-black women. Time from first HCP contact to diagnosis represented, on average, 58% to 79% of the diagnostic journey in each setting except Nigeria where most women presented directly to the diagnostic hospital with advanced disease. The median number of HCPs visited was 1 to 4 per woman, but time intervals between visits were long. Women who attributed their initial symptoms to cancer had a 4.1 months (absolute) reduced diagnostic journey than those who did not, while less-educated (none/primary) women had a 3.6 months longer journey than more educated women. In most settings the long journey to breast cancer diagnosis was not primarily due to late first presentation but to prolonged delays after first presentation to diagnosis. Promotion of breast cancer awareness and implementation of accelerated referral pathways for women with suspicious symptoms are vital to downstaging the disease in the region.

Abstract
OBJECTIVE This study aimed to assess miRNA-195 expression in the tumor tissues from a cohort of Brazilian female breast cancer patients undergoing neoadjuvant chemotherapy (NAC) and evaluate its correlation with various clinicopathological markers. METHODS Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to evaluate the miRNA-195 expression in tumor tissues from a cohort of female breast cancer patients undergoing NAC. This expression was then correlated with the occurrence of several distinct breast cancer molecular subtypes and other clinicopathological variables. RESULTS A total of 55 patients were included in this study, 28 (50.9%) of whom were treated using NAC. Tumor miRNA-195 expression was suppressed in breast cancer patients, regardless of their exposure to systemic treatments, histological grade, size, nodal status, and tumor-node-metastasis (TNM) staging. This was more pronounced in luminal and triple-negative patients, and patient's response to NAC was correlated with an increase in miRNA-195 expression. CONCLUSION miRNA-195 is downregulated in the tumor tissues of Brazilian breast cancer patients regardless of NAC exposure; this reinforces its role as a tumor suppressor and a potential biomarker for chemotherapy response.

Abstract
Esophageal squamous cell carcinoma (ESCC) is the predominant subtype of esophageal cancer in China, and this neoplasm is associated with high morbidity and mortality as well as clear geographical heterogeneity. Since primary prevention for ESCC lacks a clear intervention target, secondary prevention, also known as screening and early diagnosis and early treatment, has become the mainstay of ESCC prevention and control in China. ESCC screening in China has been subject to decades of evaluation and practice. However, the ESCC screening strategy currently adopted in China has encountered a developmental bottleneck. In this review, we have summarized studies and significant findings for ESCC screening and proposed advancement of screening strategies as follows: 1) evidence from randomized controlled trials is needed to support the effectiveness and health economic value of endoscopic screening for ESCC; 2) the current traditional screening and surveillance strategies warrant reform, and a risk-prediction-based precision strategy should be established; and 3) a deeper understanding of the value of opportunistic screening in the prevention and control of ESCC in China is called for. Due to the low absolute prevalence of precancerous lesions, substantial investment of resources and nonnegligible risks of invasive screening techniques, precision and individualization should be the main direction of cancer screening programs for the future. We advocate cooperation on the part of Chinese scientists to solve this major China-specific health problem in the next decades.

Abstract
OBJECTIVE To evaluate the distribution of the main sociodemographic and clinical-pathological characteristics in women with breast cancer according to the molecular profile by immunohistochemistry. METHODS A cross-sectional, retrospective, analytical and quantitative study was performed, with an analysis of 137 medical records from January 2015 to December 2018 of women attending the High Complexity in Oncology Unit of the city of Imperatriz, state of Maranhão, Brazil. The immunohistochemical profile of tumors based on the estrogen and progesterone receptor, Human Epidermal growth factor Receptor-type 2 (HER2) overexpression and Ki67 cell proliferation index was defined, from which six molecular subtypes were determined: luminal A, luminal B-HER2 negative, luminal B-HER2 positive, triple negative, overexpression of HER2 and inconclusive. RESULTS A total of 52.6% of the patients were postmenopausal, mean age 52.1 years old, brown (56.2%), had a schooling level < 9 years (40%), staging > IIB (52.6%) and 23.4% had metastasis. Invasive ductal carcinoma accounted for 84.7%, tumor size was 2 to 5 cm (48.9%), with lymph node involvement (56.2%), axillary lymphadenectomy in 67.2%, and mastectomy in 73.7% of the patients. The most frequent molecular subtype was the luminal B-HER2 negative (36.5%), and the luminal A subtype showed characteristics of better prognosis when compared with the others. CONCLUSION It was concluded that in the association of molecular subtypes with sociodemographic and clinical-pathological characteristics, there were no statistically significant results obtained, except for complementary therapy, referring to hormone therapy, and there was a high index of metastasis at diagnosis, which was a worrying factor and indicative of failures in the screening and early diagnosis of this population.

[PMID: 33295593 PMCID: PMC7688260 DOI: 10.11606/s1518-8787.2020054002255] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2019] [Accepted: 03/17/2020] [Indexed: 12/29/2022] Open
Abstract
OBJECTIVE: to describe the trend of mortality from general cancer and more frequent types among men and women living in the Capitals and other municipalities of the five macro-regions of Brazil between 1978 and 2017. METHODS: Time series study with mortality data corrected by redistribution of ill-defined causes. Proportional cancer mortality was calculated for Brazil and regions. The annual percentage change in rates for total cancer and specific types in each segment and in the selected unit of analysis was calculated by generalized linear regression with Gaussian binding. RESULTS: the proportion of cancer increased progressively for both sexes from 1978 to 2017. Important differences between the Capitals and the interior of the macro-regions were seen with disaggregated data. The greatest declines occurred for stomach cancer, except in the northern and interior regions of the Northeast, and for the cervix cancer, with a generalized fall, with the exception of the interior of the northern region. Lung cancer decreased among men in the Southeast and South regions and had a generalized increase among women. Breast and prostate cancers tended to decrease in the Southeast and South regions and among residents of the Capitals but showing an increase in the interior of the North and Northeast regions. Colorectal cancer had a general tendency to increase; with stability among men in the Capitals of the South region and among women of the Southeast and Midwest regions and, since 2007, a decrease among women in the South region. CONCLUSIONS: Cancer mortality showed great variation among residents of capitals and the interior of the country's major regions. Clear decrease in mortality was seen for the main types in the Southeast and South regions. The North and Northeast regions have patterns compatible with cancers associated with poverty, while the large increase of the cancers related to sedentary lifestyle stand out.

Abstract
It is estimated that there were 198,840 new cases of breast cancer (BC) in Brazil between 2020 and 2022. Young women who are affected by invasive BC with a triple-negative phenotype generally present more aggressive tumors that are intrinsically resistant to targeted therapies. This study evaluated the phenotypic and histological profile of BC in women up to the age of 40 years. Between 2015 and 2017, we identified 255 women with positive biopsy for carcinoma and with immunohistochemical panel, 51.76% who had a profile for luminal B (n = 132); 22.74% for triple-negative (n = 58). Of the samples, 65.88% presented histology as invasive ductal carcinoma – nonspecial type (n = 168). The results are in accordance with the literature regarding the high prevalence of triple-negative BC in young women and histological type invasive ductal carcinoma – nonspecial type.

Abstract
Introduction MicroRNA-21 (miRNA-21) has been described as one of the most significantly upregulated miRNAs in human breast cancer. However, limited knowledge exists on miRNA-21 expression in breast cancer tissue after neoadjuvant chemotherapy (NAC). Purpose The aim of this study was to assess miRNA-21 expression in the tumor tissues of Brazilian patients with breast cancer who underwent NAC and its correlation with clinicopathological variables. Patients and Methods Utilizing qRT-PCR, miRNA-21 expression in tumor tissue was measured in a cohort of female patients with breast cancer who underwent NAC. The correlation of miRNA-21 expression with breast cancer molecular subtypes and other clinicopathological variables was also assessed. Results A total of 55 patients were included in the study, and 28 (50.9%) underwent NAC. miRNA-21 was upregulated in patients with breast cancer, regardless of previous exposure to chemotherapy, molecular subtypes, tumor-node-metastasis (TNM) staging and lymph node status of the axilla. miRNA-21 expression did not differ between patients with breast cancer who achieved a pathologic complete response after NAC and healthy controls. Conclusion miRNA-21 was upregulated in the tumor tissue of Brazilian patients with breast cancer regardless of NAC treatment, which reinforces its role as an “oncomiR” and a potential biomarker.

Abstract
When breast cancer is detected and treated early, the chances of survival are very high. However, women in many settings face complex barriers to early detection, including social, economic, geographic, and other interrelated factors, which can limit their access to timely, affordable, and effective breast health care services. Previously, the Breast Health Global Initiative (BHGI) developed resource-stratified guidelines for the early detection and diagnosis of breast cancer. In this consensus article from the sixth BHGI Global Summit held in October 2018, the authors describe phases of early detection program development, beginning with management strategies required for the diagnosis of clinically detectable disease based on awareness education and technical training, history and physical examination, and accurate tissue diagnosis. The core issues address include finance and governance, which pertain to successful planning, implementation, and the iterative process of program improvement and are needed for a breast cancer early detection program to succeed in any resource setting. Examples are presented of implementation, process, and clinical outcome metrics that assist in program implementation monitoring. Country case examples are presented to highlight the challenges and opportunities of implementing successful breast cancer early detection programs, and the complex interplay of barriers and facilitators to achieving early detection for breast cancer in real-world settings are considered.

Breast cancer patient advocacy: A qualitative study of the challenges and opportunities for civil society organizations in low-income and middle-income countries. Cancer 2020; 126 Suppl 10:2439-2447. [PMID: 32348570 DOI: 10.1002/cncr.32852] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2020] [Revised: 02/12/2020] [Accepted: 03/01/2020] [Indexed: 12/19/2022]
Abstract
BACKGROUND Breast cancer advocacy movements, driven by advocate-led civil society organizations (CSOs), have proven to be a powerful force for the advancement of cancer control in high-income countries (HICs). However, although patient advocacy movements are growing in low-income and middle-income countries (LMICs) in response to an increasing cancer burden, the experiences and needs of advocate-led breast cancer CSOs in LMICs is understudied. METHODS The authors conducted a qualitative study using in-depth interviews and focus group discussions with 98 participants representing 23 LMICs in Eastern Europe, Central Asia, East and Southern Africa, and Latin America. RESULTS Despite geographic, cultural, and socioeconomic differences, the common themes that emerged from the data across the 3 regions are strikingly similar: trust, knowledge gaps, stigma, sharing experiences, and sustainability. The authors identified common facilitators (training/education, relationship building/networking, third-party facilitators, and communication) and barriers (mistrust, stigma, organizational fragility, difficulty translating HIC strategies) to establishing trust, collaboration, and advancing cancer advocacy efforts. To the authors' knowledge, the current study is the first to describe the role that coalitions and regional networks play in advancing breast cancer advocacy in LMICs across multiple regions. CONCLUSIONS The findings of the current study corroborate the importance of investing in 3-way partnerships between CSOs, political leaders, and health experts. When provided with information that is evidence-based and resource appropriate, as well as opportunities to network, advocates are better equipped to achieve their goals. The authors propose that support for CSOs focuses on building trust through increasing opportunities for engagement, disseminating best practices and evidence-based information, and fostering the creation of platforms for partnerships and networks.
