Abstract
We present a survey of the current state-of-the-art in breast cancer detection and prognosis. We analyze the evolution of Artificial Intelligence-based approaches from using just uni-modal information to multi-modality for detection and how such paradigm shift facilitates the efficacy of detection, consistent with clinical observations. We conclude that interpretable AI-based predictions and ability to handle class imbalance should be considered priority.

Lemos LLP, Souza MC, Guerra AA, Piazza T, Araújo RM, Cherchiglia ML. Racial disparities in breast cancer survival after treatment initiation in Brazil: a nationwide cohort study. 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.

Abstract
BACKGROUND The survival of women with early-stage breast cancer varies by racial group. Filipino women with breast cancer are an understudied group and are often combined with other Asian groups. We compared clinical presentations and survival rates for Filipino and White women with breast cancer diagnosed in the United States. METHODS We conducted a retrospective cohort study of women with breast cancer diagnosed between 2004 and 2015 in the SEER18 registries database. We compared crude survival between Filipino and White women. We then calculated adjusted hazard ratios (HR) in a propensity-matched design using the Cox proportional hazards model. RESULTS There were 10,834 Filipino (2.5%) and 414,618 White women (97.5%) with Stage I-IV breast cancer in the SEER database. The mean age at diagnosis was 57.5 years for Filipino women and 60.8 years for White women (p < 0.0001). Filipino women had more high-grade and larger tumors than White women and were more likely to have node-positive disease. Among women with Stage I-IIIC breast cancer, the crude 10-year breast cancer-specific survival rate was 91.0% for Filipino and 88.9% for White women (HR 0.81, 95% CI 0.74-0.88, p < 0.01). In a propensity-matched analysis, the HR was 0.73 (95% CI 0.66-0.81). The survival advantage for Filipino women was present in subgroups defined by age of diagnosis, nodal status, estrogen receptor status, and HER2 receptor status. CONCLUSION In the United States, Filipino women often present with more advanced breast cancers than White women, but experience better breast cancer-specific survival.

MicroRNA Dysregulation in Early Breast Cancer Diagnosis: A Systematic Review and Meta-Analysis. Int J Mol Sci 2023; 24:ijms24098270. [PMID: 37175974 PMCID: PMC10179484 DOI: 10.3390/ijms24098270] [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: 02/23/2023] [Revised: 04/17/2023] [Accepted: 04/24/2023] [Indexed: 05/15/2023] Open
Abstract
Breast cancer continues to be the leading cause of death in women worldwide. Mammography, which is the current gold standard technique used to diagnose it, presents strong limitations in early ages where breast cancer is much more aggressive and fatal. MiRNAs present in numerous body fluids might represent a new line of research in breast cancer biomarkers, especially oncomiRNAs, known to play an important role in the suppression and development of neoplasms. The aim of this systematic review and meta-analysis was to evaluate dysregulated miRNA biomarkers and their diagnostic accuracy in breast cancer. Two independent researchers reviewed the included studies according to the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. A protocol for this review was registered in PROSPERO with the registration number "CRD42021256338". Observational case-control-based studies analyzing concentrations of microRNAs which have been published within the last 10 years were selected, and the concentrations of miRNAs in women with breast cancer and healthy controls were analyzed. Random-effects meta-analyses of miR-155 were performed on the studies which provided enough data to calculate diagnostic odds ratios. We determined that 34 microRNAs were substantially dysregulated and could be considered biomarkers of breast cancer. Individually, miR-155 provided better diagnostic results than mammography on average. However, when several miRNAs are used to screen, forming a panel, sensitivity and specificity rates improve, and they can be associated with classic biomarkers such us CA-125 or CEA. Based on the results of our meta-analysis, miR-155 might be a promising diagnostic biomarker for this patient population.

Abstract
BACKGROUND Although the incidence of breast cancer is highest in White women, Black women die at a higher rate. Our aim was to compare the relative association between race/ethnicity and socioeconomic status on breast cancer mortality. METHODS We identified female breast cancer patients diagnosed between 2007 - 2011 and followed through 2016 in the SEER database. Patients were grouped into socioeconomic quartiles by a prosperity index. The primary outcome of interest was 5-year cancer-specific survival. RESULTS A total of 286,520 patients were included. Five-year survival was worst for Black women compared to other races/ethnicities in each socioeconomic quartile. When compared to White women in the lowest quartile, Black women in the lowest quartile, 2nd quartile, and 3rd quartile experienced the lowest 5-year survival rates (Hazard ratio 1.33, 1.23, 1.20; P < 0.01). CONCLUSION Regarding cancer mortality, only in the most prosperous quartile do Black women achieve a similar outcome to the poorest quartile White women.

Abstract
BACKGROUND Breast conservation surgery (BCS) and mastectomy have equivalent survivability. However, perception of surgical benefit may be affected by breast cancer subtypes, impacting procedure choice. We evaluate surgical management among non-Hispanic Black (NHB) and White (NHW) breast cancer patients based on subtypes. METHODS Queried the National Cancer Database (NCDB) including BCS eligible women with T1 (<2cm) breast cancer between 2011 and 2016. We selected NHB and NHW women and evaluated differences in sociodemographic variables and treatment including surgery. To determine factors associated with receipt of BCS, a multivariable logistic regression analysis was performed adjusting for age, race, surgery type and breast cancer subtypes. RESULTS Analyzed 390,278 women with 89.7% NHW and 10.3% NHB, of mean age 63 years. 55.4% vs. 53.5% of NHW compared to NHB women had BCS (p<.001) as initial cancer therapy. Statistically significant differences between NHB and NHW in surgery were found on univariate analysis in all breast cancer subtypes except Luminal B. NHB women with TNBC and Luminal A subtypes were more likely to undergo BCS on multivariate analysis. CONCLUSIONS Significant differences are found in the surgical management of breast cancer with Black women more likely to receive BCS, less likely to undergo mastectomy compared to White counterparts even with TNBC or her-2+ subtypes. Understanding surgical decision making and how knowledge of subtype is applied deserves further study in women of diverse racial and ethnic groups.

Abstract
Triple-negative breast cancer (TNBC) is a kind of breast cancer that lacks estrogen, progesterone, and human epidermal growth factor receptor 2. This cancer is responsible for more than 15–20% of all breast cancers and is of particular research interest as it is therapeutically challenging mainly because of its low response to therapeutics and highly invasive nature. The non-availability of specific treatment options for TNBC is usually managed by conventional therapy, which often leads to relapse. The focus of this review is to provide up-to-date information related to TNBC epidemiology, risk factors, metastasis, different signaling pathways, and the pathways that can be blocked, immune suppressive cells of the TNBC microenvironment, current and investigation therapies, prognosis, and the role of artificial intelligence in TNBC diagnosis. The data presented in this paper may be helpful for researchers working in the field to obtain general and particular information to advance the understanding of TNBC and provide suitable disease management in the future.

Abstract
The COVID-19 pandemic has had critical consequences for cancer care delivery, including altered treatment protocols and delayed services that may affect patients’ quality of life and long-term survival. Breast cancer patients from minoritized racial and ethnic groups already experience worse outcomes, which may have been exacerbated by treatment delays and social determinants of health (SDoH). This protocol details a mixed-methods study aimed at comparing cancer care disruption among a diverse sample of women (non-Hispanic White, non-Hispanic Black/African American, and Hispanic/Latina) and assessing how proximal, intermediate, and distal SDoH differentially contribute to care continuity and health-related quality of life. An embedded mixed-methods design will be implemented. Eligible participants will complete an online survey, followed by a semi-structured interview (with a subset of participants) to further understand factors that influence continuity of care, treatment decision-making, and self-reported engagement. The study will identify potentially modifiable factors to inform future models of care delivery and improve care transitions. These data will provide the necessary evidence to inform whether a subsequent, multilevel intervention is warranted to improve quality of care delivery in the COVID-19 aftermath. Additionally, results can be used to identify ways to leverage existing social resources to help manage and support patients’ outcomes.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC), an increasingly used method for breast cancer patients, has the potential to downstage patient tumors and thereby have an impact on surgical options for treatment of the breast and axilla. Previous studies have identified racial disparities in tumor heterogeneity, nodal recurrence, and NAC completion. This report compares the effects of NAC response among non-Hispanic white women and black women in relation to surgical treatment of the breast and axilla. METHODS A retrospective review of 85,303 women with stages 1 to 3 breast cancer in the National Cancer Database who received NAC between 1 January 2010 and 31 December 2016 was conducted. Differences in sociodemographic and clinical variables between black patients and white patients with breast cancer were tested. RESULTS The study identified 68,880 non-Hispanic white and 16,423 non-Hispanic black women who received NAC. The average age at diagnosis was 54.8 years for the white women versus 52.5 years for the black women. A higher proportion of black women had stage 3 disease, more poorly differentiated tumors, and triple-negative subtype. The black women had lower rates of complete pathologic response, more breast-conservation surgery, and higher rates of axillary lymph node dissection, but fewer sentinel lymph node biopsies. Axillary management for the women who were downstaged showed more use of axillary lymph node dissection for black women compared with sentinel lymph node biopsy. CONCLUSIONS The black patients were younger at diagnosis, had more advanced disease, and were more likely to have breast-conservation surgery. De-escalating axillary surgery is being adopted increasingly but used disproportionately for white women.

Abstract
Simple Summary Breast cancer is the most common cancer among women. It is estimated that 2.3 million new cases of BC are diagnosed globally each year. Based on mRNA gene expression levels, BC can be divided into molecular subtypes that provide insights into new treatment strategies and patient stratifications that impact the management of BC patients. This review addresses the overview on the BC epidemiology, risk factors, classification with an emphasis on molecular types, prognostic biomarkers, as well as possible treatment modalities. Abstract Breast cancer (BC) is the most frequently diagnosed cancer in women worldwide with more than 2 million new cases in 2020. Its incidence and death rates have increased over the last three decades due to the change in risk factor profiles, better cancer registration, and cancer detection. The number of risk factors of BC is significant and includes both the modifiable factors and non-modifiable factors. Currently, about 80% of patients with BC are individuals aged >50. Survival depends on both stage and molecular subtype. Invasive BCs comprise wide spectrum tumors that show a variation concerning their clinical presentation, behavior, and morphology. Based on mRNA gene expression levels, BC can be divided into molecular subtypes (Luminal A, Luminal B, HER2-enriched, and basal-like). The molecular subtypes provide insights into new treatment strategies and patient stratifications that impact the management of BC patients. The eighth edition of TNM classification outlines a new staging system for BC that, in addition to anatomical features, acknowledges biological factors. Treatment of breast cancer is complex and involves a combination of different modalities including surgery, radiotherapy, chemotherapy, hormonal therapy, or biological therapies delivered in diverse sequences.

Abstract
PURPOSE The affect of race on breast cancer prognosis is not well understood. We compared crude and adjusted breast cancer survival rates of Chinese women versus White women in the United States. METHODS We conducted a cohort study of Chinese and White women with breast cancer diagnosed between 2004 to 2015 in the SEER 18 registries database. We abstracted information on age at diagnosis, tumor size, grade, lymph node status, receptor status, surgical treatment, receipt of radiotherapy and chemotherapy, and death. We compared crude breast cancer–specific mortality between the two ethnic groups. We calculated adjusted hazard ratios (HRs) in a propensity-matched design using the Cox proportional hazards model. P < .05 was considered statistically significant. RESULTS There were 7,553 Chinese women (1.8%) and 414,618 White women (98.2%) with stage I-IV breast cancer in the SEER database. There were small differences in demographics, nodal burden, and clinical stage between Chinese and White women. Ten-year breast cancer–specific survival was 88.8% for Chinese women and 85.6% for White women (HR, 0.73; 95% CI, 0.67 to 0.80; P < .0001). In a propensity-matched analysis among women with stage I–IIIC breast cancer, the HR was 0.71 (95% CI, 0.62 to 0.81; P < .0001). Annual mortality rates in White women exceeded those in Chinese women for the first 9 years after diagnosis. CONCLUSION Chinese women in the United States have superior breast cancer–specific survival compared with White women. The reason for the observed difference is not clear. Differences in demographic and tumor features between Chinese and White women with breast cancer may contribute to the disparity, as may the possibility of intrinsic biologic differences.

Abstract
African-American/Black women have more aggressive breast cancer subtypes, are diagnosed at younger ages, and have an increasing incidence rate. These disparities have resulted in Black women continuing to experience the highest mortality rate from breast cancer of any US racial or ethnic group. However, national screening mammography guidelines do not reflect the high-risk status of Black women. Here we review breast cancer screening guidelines and address the lack of inclusion of the specific needs of Black women. In order to equitably care for the health needs of Black women, high-risk designation would improve access to earlier screening and supplemental imaging including breast MRI.

Public health insurance and cancer-specific mortality risk among patients with breast cancer: A prospective cohort study in China. Int J Cancer 2020; 148:28-37.

Abstract
Little is known about how health insurance policies, particularly in developing countries, influence breast cancer prognosis. Here, we examined the association between individual health insurance and breast cancer-specific mortality in China. We included 7436 women diagnosed with invasive breast cancer between 2009 and 2016, at West China Hospital, Sichuan University. The health insurance plan of patient was classified as either urban or rural schemes and was also categorized as reimbursement rate (ie, the covered/total charge) below or above the median. Breast cancer-specific mortality was the primary outcome. Using Cox proportional hazards models, we calculated hazard ratios (HRs) for cancer-specific mortality, contrasting rates among patients with a rural insurance scheme or low reimbursement rate to that of those with an urban insurance scheme or high reimbursement rate, respectively. During a median follow-up of 3.1 years, we identified 326 deaths due to breast cancer. Compared to patients covered by urban insurance schemes, patients covered by rural insurance schemes had a 29% increased cancer-specific mortality (95% CI 0%-65%) after adjusting for demographics, tumor characteristics and treatment modes. Reimbursement rate below the median was associated with a 42% increased rate of cancer-specific mortality (95% CI 11%-82%). Every 10% increase in the reimbursement rate is associated with a 7% (95% CI 2%-12%) reduction in cancer-specific mortality risk, particularly in patients covered by rural insurance schemes (26%, 95% CI 9%-39%). Our findings suggest that underinsured patients face a higher risk of breast cancer-specific mortality in developing countries.

Abstract
BACKGROUND There is increasing recognition of the importance of early incorporation of palliative care services in the care of patients with advanced cancers. Hospice-based palliative care remains underutilized for black patients with cancer, and there is limited literature on racial disparities in use of non-hospice-based palliative care services for patients with cancer. OBJECTIVE The primary objective of this study is to describe racial differences in the use of inpatient palliative care consultations (IPCC) for patients with advanced cancer who are admitted to a hospital in the United States. DESIGN This retrospective cohort study analyzed 204 175 hospital admissions of patients with advanced cancers between 2012 and 2014. The cohort was identified through the National Inpatient Dataset. International Classification of Disease, Ninth Revision codes were used to identify receipt of a palliative care consultation. RESULTS Of this, 57.7% of those who died received IPCC compared to 10.5% who were discharged alive. In multivariable logistic regression models, black patients discharged from the hospital, were significantly less likely to receive a palliative care consult compared to white patients (odds ratio [OR] black: 0.69, 95% CI: 0.62-0.76). CONCLUSIONS Death during hospitalization was a significant modifier of the relationship between race and receipt of palliative care consultation. There are significant racial disparities in the utilization of IPCC for patients with advanced cancer.
