Delays in breast cancer care by race and sexual orientation: Results from a national survey with diverse women in the United States

Socioeconomic inequities in care experienced by women with breast cancer in England: An intersectional cross-sectional study

PURPOSE

Guided by the Intersectionality Framework, we examined the differential in breast cancer care experience across population subgroups in England.

METHODS

Secondary data analysis using the 2017/2018 National Cancer Patient Experience Surveys. We used disaggregated descriptive statistics (mean, standard errors, 95% confidence interval) to analyse 26,030 responses from female breast cancer patients to a question relating to overall care experience categorised by age, ethnicity, and sexual orientation in their intersection with social position. We then used logistic regression to investigate the odds (Odds Ratio (OR), 95% confidence intervals) of reporting positive care experience adjusting for patient, clinical, and Trust level factors.

RESULTS

Poorer care experience was predominantly reported by the most deprived younger and minoritised ethnic groups. Statistically significant findings were observed in adjusted multivariable analyses. Compared to patients aged 65-74 years, younger respondents were less likely to rate their care favourably (16-34 years old ORadj. = 0.55 (0.36-0.84). Compared to White British, Asian (ORadj. = 0.51 (0.39-0.66)) and Black African women (ORadj. = 0.53 (0.33-0.88)) were less likely to rate their care favourably. The least affluent respondents were less likely to rate their care favourably (ORadj. = 0.79 (0.64-0.97)).

CONCLUSION

There is evidence of inequity in overall cancer care experience among female breast cancer patients in England, particularly among women living at the specific intersection of age, ethnicity, and socioeconomic position. Future research is necessary to understand the mechanisms underlying breast cancer inequities. Policymakers, commissioners, and providers should consider the existence of multiple forms of marginalisation to inform improvement initiatives targeting patients at higher risk of vulnerability.

Cancer in people who identify as lesbian, gay, bisexual, transgender, queer, or gender-nonconforming

BACKGROUND

Individuals who identify as lesbian, gay, bisexual, transgender, queer, intersex, or gender-nonconforming (LGBTQ+) experience discrimination and minority stress that may lead to elevated cancer risk.

METHODS

In the absence of population-based cancer occurrence information for this population, this article comprehensively examines contemporary, age-adjusted cancer risk factor and screening prevalence using data from the National Health Interview Survey, Behavioral Risk Factor Surveillance System, and National Youth Tobacco Survey, and provides a literature review of cancer incidence and barriers to care.

RESULTS

Lesbian, gay, and bisexual adults are more likely to smoke cigarettes than heterosexual adults (16% compared to 12% in 2021-2022), with the largest disparity among bisexual women. For example, 34% of bisexual women aged 40-49 years and 24% of those 50 and older smoke compared to 12% and 11%, respectively, of heterosexual women. Smoking is also elevated among youth who identify as lesbian, gay, or bisexual (4%) or transgender (5%) compared to heterosexual or cisgender (1%). Excess body weight is elevated among lesbian and bisexual women (68% vs. 61% among heterosexual women), largely due to higher obesity prevalence among bisexual women (43% vs. 38% among lesbian women and 33% among heterosexual women). Bisexual women also have a higher prevalence of no leisure-time physical activity (35% vs. 28% among heterosexual women), as do transgender individuals (30%-31% vs. 21%-25% among cisgender individuals). Heavier alcohol intake among lesbian, gay, and bisexual individuals is confined to bisexual women, with 14% consuming more than 7 drinks/week versus 6% of heterosexual women. In contrast, prevalence of cancer screening and risk reducing vaccinations in LGBTQ+ individuals is similar to or higher than their heterosexual/cisgender counterparts except for lower cervical and colorectal cancer screening among transgender men.

CONCLUSIONS

People within the LGBTQ+ population have a higher prevalence of smoking, obesity, and alcohol consumption compared to heterosexual and cisgender people, suggesting a higher cancer burden. Health systems have an opportunity to help inform these disparities through the routine collection of information on sexual orientation and gender identity to facilitate cancer surveillance and to mitigate them through education to increase awareness of LGBTQ+ health needs.

Construction of polypyrrole nanoparticles with a rough surface for enhanced chemo-photothermal therapy against triple negative breast cancer

Triple-negative breast cancer (TNBC) is the most malignant subtype of breast cancer, characterized by aggressive malignancy and a poor prognosis. Emerging nanomedicine-based combination therapy represents one of the most promising strategies for combating TNBC. Polypyrrole nanoparticles (PPY) are excellent drug delivery vehicles with outstanding photothermal performances. However, the impact of morphology on PPY's drug loading efficiency and photothermal properties remains largely unexplored. In this study, we propose that pluronic P123 can assist in the synthesis of polypyrrole nanoparticles with rough surfaces (rPPY). During the synthesis, P123 formed small micelles around the nanoparticle surface, which were later removed, resulting in small pits and cavities in rPPY. Subsequently, the rPPY was loaded with the chemotherapy drug gemcitabine (Gem@rPPY) for chemo-photothermal therapy against TNBCs. Our results demonstrate that rPPY exhibited superior photothermal performance and significantly enhanced drug loading efficiency by five times compared to smooth PPY nanoparticles. In vitro assessments confirmed Gem@rPPY's robust photothermal properties by efficiently converting light into heat. Cell culture experiments with 4T1 cells and a TNBC mice model revealed significant tumor suppression upon Gem@rPPY administration, emphasizing its efficacy in inducing apoptosis. Toxicity evaluations demonstrated minimal adverse effects both in vitro and in vivo, highlighting the biocompatibility of Gem@rPPY. Overall, this study introduces a promising combination therapy nanoplatform that underscores the importance of surface engineering to enhance therapeutic outcomes and overcome current limitations in TNBC therapy.

Impact of microRNA variants on PI3K/AKT signaling in triple-negative breast cancer: comprehensive review

Breast cancer (BC) is a significant cause of cancer-related mortality, and triple-negative breast cancer (TNBC) is a particularly aggressive subtype associated with high mortality rates, especially among younger females. TNBC poses a considerable clinical challenge due to its aggressive tumor behavior and limited therapeutic options. Aberrations within the PI3K/AKT pathway are prevalent in TNBC and correlate with increased therapeutic intervention resistance and poor outcomes. MicroRNAs (miRs) have emerged as crucial PI3K/AKT pathway regulators influencing various cellular processes involved in TNBC pathogenesis. The levels of miRs, including miR-193, miR-4649-5p, and miR-449a, undergo notable changes in TNBC tumor tissues, emphasizing their significance in cancer biology. This review explored the intricate interplay between miR variants and PI3K/AKT signaling in TNBC. The review focused on the molecular mechanisms underlying miR-mediated dysregulation of this pathway and highlighted specific miRs and their targets. In addition, we explore the clinical implications of miR dysregulation in TNBC, particularly its correlation with TNBC prognosis and therapeutic resistance. Elucidating the roles of miRs in modulating the PI3K/AKT signaling pathway will enhance our understanding of TNBC biology and unveil potential therapeutic targets. This comprehensive review aims to discuss current knowledge and open promising avenues for future research, ultimately facilitating the development of precise and effective treatments for patients with TNBC.

Understanding and tackling cancer inequities: What opportunities does intersectionality offer researchers, policymakers, and providers? A scoping review

PROBLEM IDENTIFICATION

We summarised the international evidence relating to the role of intersectionality in patients' lived experience of inequities along the cancer care pathway. We produced guidance to use intersectionality in future research.

LITERATURE SEARCH

We included 42 articles published between 1989 to 2023 that used intersectionality to guide the study and interpretation of inequities in cancer care.

DATA EVALUATION/SYNTHESIS

Articles predominantly comprised North American (n = 37), followed by European (n = 4) and Asian (n = 1) studies. Similar compounding effects of racism, homophobia, and discrimination across countries exacerbated inequities in cancer care experience and cancer outcomes particularly for women of color and sexual/gender minority groups. Professionals' knowledge, attitudes, and behaviors toward minoritised groups affected patient-provider relationships and influenced cancer patients' psychosocial responses.

CONCLUSION

Intersectionality provides a framework to assess the personal, interpersonal, and structural processes through which cancer inequities manifest within and across countries.

"It's probably an STI because you're gay": a qualitative study of diagnostic error experiences in sexual and gender minority individuals

BACKGROUND

There is a critical need to identify specific causes of and tailored solutions to diagnostic error in sexual and gender minority (SGM) populations.

PURPOSE

To identify challenges to diagnosis in SGM adults, understand the impacts of patient-reported diagnostic errors on patients' lives and elicit solutions.

METHODS

Qualitative study using in-depth semistructured interviews. Participants were recruited using convenience and snowball sampling. Recruitment efforts targeted 22 SGM-focused organisations, academic centres and clinics across the USA. Participants were encouraged to share study details with personal contacts. Interviews were analysed using codebook thematic analysis.

RESULTS

Interviewees (n=20) ranged from 20 to 60 years of age with diverse mental and physical health symptoms. All participants identified as sexual minorities, gender minorities or both. Thematic analysis revealed challenges to diagnosis. Provider-level challenges included pathologisation of SGM identity; dismissal of symptoms due to anti-SGM bias; communication failures due to providers being distracted by SGM identity and enforcement of cis-heteronormative assumptions. Patient-level challenges included internalised shame and stigma. Intersectional challenges included biases around factors like race and age. Patient-reported diagnostic error led to worsening relationships with providers, worsened mental and physical health and increased self-advocacy and community-activism. Solutions to reduce diagnostic disparities included SGM-specific medical education and provider training, using inclusive language, asking questions, avoiding assumptions, encouraging diagnostic coproduction, upholding high care standards and ethics, involving SGM individuals in healthcare improvement and increasing research on SGM health.

CONCLUSIONS

Anti-SGM bias, queerphobia, lack of provider training and heteronormative attitudes hinder diagnostic decision-making and communication. As a result, SGM patients report significant harms. Solutions to mitigate diagnostic disparities require an intersectional approach that considers patients' gender identity, sexual orientation, race, age, economic status and system-level changes.

Scoping review of experiences of sexual minority women treated for breast cancer

PURPOSE

To summarize and critique research on the experiences and outcomes of sexual minority women (SMW) treated with surgery for breast cancer through systematic literature review.

METHODS

A comprehensive literature search identified studies from the last 20 years addressing surgical experiences and outcomes of SMW breast cancer survivors. Authors performed a quality assessment and thematic content analysis to identify emergent themes.

RESULTS

The search yielded 121 records; eight qualitative studies were included in the final critical appraisal. Quality scores for included studies ranged 6-8 out of 10. Experiences and outcomes of SMW breast cancer survivors were organized by major themes: 1) Individual, 2) Interpersonal, 3) Healthcare System, and 4) Sociocultural and Discursive.

CONCLUSIONS

SMW breast cancer survivors have unique experiences of treatment access, decision-making, and quality of life in survivorship. SMW breast cancer survivors' personal values, preferences, and support network are critical considerations for researchers and clinicians.

Engaging Black sexual minority women in breast cancer research: Lessons in community partnerships

BACKGROUND

Black sexual minority women (BSMW) face significant breast cancer health inequities and are underrepresented in health research because of historical and present-day exclusion. However, there exists no peer-reviewed literature on best practices for the inclusion of BSMW in cancer research. "Our Breast Health: The Access Project" was a national primary data collection study in June 2018 through October 2019 that aimed to identify facilitators and barriers to breast cancer care among BSMW, and that successfully recruited the highest number of BSMW for any national breast cancer screening study at the time of its publication.

METHODS

The present analysis highlights best practices for reaching BSMW by examining by how effective various recruitment sources were at recruiting BSMW. Recruitment partners were grouped into several categories: (1) cancer focused, (2) Black women or sexual minority women focused, (3) BSMW focused, (4) social media, and (5) other. Then logistic regression was used to estimate the odds that a particular recruitment source category could recruit BSMW compared with other categories.

RESULTS

Partnerships with community-based organizations led by and intended for BSMW were the most successful at recruiting BSMW, demonstrating the importance of an intersectional approach to recruitment. Community-based organizations focused on BSMW specifically were 26 times more successful in recruiting BSMW to the study compared with recruiting Black women who were not sexual minorities (odds ratio, 26.43 [95% CI, 7.50-93.10]).

CONCLUSIONS

Successful recruitment enables breast cancer research grounded in the perspectives of BSMW, which can generate key findings that have the potential to remedy longstanding health inequities for this population.

Recent advances in targeted strategies for triple-negative breast cancer

Triple-negative breast cancer (TNBC), a highly aggressive subtype of breast cancer, negatively expresses estrogen receptor, progesterone receptor, and the human epidermal growth factor receptor 2 (HER2). Although chemotherapy is the main form of treatment for patients with TNBC, the effectiveness of chemotherapy for TNBC is still limited. The search for more effective therapies is urgent. Multiple targeted therapeutic strategies have emerged according to the specific molecules and signaling pathways expressed in TNBC. These include PI3K/AKT/mTOR inhibitors, epidermal growth factor receptor inhibitors, Notch inhibitors, poly ADP-ribose polymerase inhibitors, and antibody-drug conjugates. Moreover, immune checkpoint inhibitors, for example, pembrolizumab, atezolizumab, and durvalumab, are widely explored in the clinic. We summarize recent advances in targeted therapy and immunotherapy in TNBC, with the aim of serving as a reference for the development of individualized treatment of patients with TNBC in the future.

Cultural Competence in the Care of LGBTQ+ Patients: A Primer for Breast/Chest Centers

The number of individuals identifying as lesbian, gay, bisexual, transgender, queer/questioning (LGBTQ+) has doubled over the past 10 years, and this figure continues to rise. The LGBTQ+ community is diverse, encompassing a vast array of differences in gender identity and sexual orientation. Additionally, it is inclusive of people from all races, ethnicities, religions, and socioeconomic backgrounds. This intersectionality of identities and experiences impacts both access to health care and its delivery. Barriers to care for this population are multifactorial and include stigma, discrimination, bias, limited role models, issues with insurance coverage, lack of education and training for health care providers, and lack of research on LGBTQ+ health-related issues. Specific to breast cancer, the screening recommendations for this group are influenced not only by risk but also by gender-affirming hormonal and surgical therapies. This article will provide an overview of the LGBTQ+ population, review breast cancer screening compliance and recommendations, summarize the multitude of health disparities, and offer potential interventions to improve care delivery at the individual, facility, organizational, and health policy levels.

Sexual Minority Women, Health Care Discrimination, and Poor Health Outcomes: A Mediation Model Through Delayed Care

Purpose: Sexual minority (SM) women are a heterogeneous group who commonly report negative health care experiences at the intersection of their diverse sexual orientations and racial/ethnic identities. However, scarce research has evaluated how negative health care experiences may affect health outcomes among this population. Informed by the Health Equity Promotion Model for SM health, this study evaluated mediation models in which delayed care mediated the association between provider discrimination and poor health outcomes in SM women. Sexual orientation (plurisexual or monosexual) and race/ethnicity (women of color or White) were evaluated as moderators of the direct and indirect pathways. Methods: The sample included SM women (N = 1530) from the nationally representative Association of American Medical Colleges biannual Consumer Survey of Healthcare Access (2010-2020). Mediation models were conducted with lavaan structural equation modeling software. Results: Reported discrimination from a health care provider was associated with higher physical and emotional impairment, and these associations were partially mediated through delayed care. Sexual orientation and race/ethnicity also moderated several indirect and direct pathways. Conclusion: Results provide evidence of delayed care as a possible mediation pathway between provider discrimination and worse health in SM women and that the strength of these associations may vary by sexual orientation and race/ethnicity. Results indicate a need for policy change and clinical trainings to reduce the harm of provider discrimination on SM women.

Breast, Prostate, Colorectal, and Lung Cancer Incidence and Risk Factors in Women Who Have Sex with Women and Men Who Have Sex with Men: A Cross-Sectional and Longitudinal Analysis Using UK Biobank

BACKGROUND

There is limited evidence about cancer incidence for lesbian, gay and bisexual women and men, although the prevalence of cancer risk factors may be higher.

AIM

To describe cancer incidence for four common cancers (breast, lung, colorectal and prostate).

METHODS

This project used UK Biobank participant data. We explored risk factor prevalence (age, deprivation, ethnicity, smoking, alcohol intake, obesity, parity, and sexual history), and calculated cancer risk, for six groups defined based on sexual history; women who have sex exclusively with men (WSEM), or women (WSEW), women who have sex with men and women (WSWM); men who have sex exclusively with women (MSEW), or men (MSEM), and men who have sex with women and men (MSWM).

RESULTS

WSEW, WSWM, MSEM, and MSMW were younger, more likely to smoke, and to live in more deprived neighbourhoods. We found no evidence of an association between sexual history and breast, colorectal, or prostate cancer in age-adjusted models. Lung cancer incidence was higher for WSWM compared with WSEM, HR (95%CI) 1.78 (1.28-2.48), p = 0.0005, and MSWM compared with MSEW, 1.43 (1.03-1.99), p = 0.031; after adjustment for smoking, this difference was no longer significant.

CONCLUSIONS

Sexual minority groups have a higher risk for lung cancer, due to greater exposure to smoking.

Sexual and gender diversity in cancer care and survivorship

PURPOSE OF THE REVIEW

Sexual and gender diverse (SGD) cancer patients possess unique identities and needs that must be considered during their cancer care. This narrative review explores the current literature on sexual and gender diversity in cancer care and survivorship, in addition to providing recommendations encouraged by the current literature.

RECENT FINDINGS

We performed a literature search for articles published in English between January 2021 and June 2022 in Medline ALL and Embase. Fifty-two studies were included in this review. The many identities encapsulated in 2SLGBTQIA+ (2 Spirited, Lesbian, Gay, Bisexual, Transgender, Queer, Intersexual, Asexual, Agender, Aromantic and all gender identities and sexual orientations that are not listed) communities each have their own unique backgrounds, needs and disparities in cancer care and survivorship. However, we also identified specific protective factors in the cancer experience of SGD patients such as reports of higher resiliency and stronger support networks. Much of the recent research features recommendations on improving cancer care by creating inclusive patient questionnaires, improving in-person and online resources, and educating healthcare providers and patient-facing staff on inclusive care.

SUMMARY

SGD patients have their own specific challenges during and following their cancer care. As the research continues to grow, we gain a better understanding of the needs of these patients and future steps to take to improve SGD patients' cancer experience.

Relationship between intersectionality and cancer inequalities: a scoping review protocol

INTRODUCTION

Persistent inequalities in cancer care and cancer outcomes exist within and between countries. However, the evidence pertaining to the root causes driving cancer inequalities is mixed. This may be explained by the inadequate attention paid to experiences of patients with cancer living at the intersection of multiple social categories (eg, social class, ethnicity). This is supported by the intersectionality framework. This framework offers an alternative lens through which to analyse and understand how these interlocking systems of oppression uniquely shape the experiences of patients with cancer and drive inequalities. In this protocol, we outline a scoping review that will systematically map what is known about the relationship between intersectionality and inequalities in care experience and cancer outcomes of patients with cancer; and to determine how the intersectionality framework has been applied in studies across the cancer care pathway and across countries.

METHODS AND ANALYSIS

This study will be guided by Arksey and O'Malley's, and Levac et al's frameworks for scoping reviews. We will identify and map the evidence on cancer inequalities and intersectionality from 1989 to present date. Electronic databases (EMBASE, PsychINFO, CINAHL, Medline, Web of Science, ProQuest) and a systematic search strategy using a combination of keywords and Boolean operators AND/OR will be used to identify relevant studies. Screening of eligible papers and data extraction will be conducted by two independent reviewers, and disagreements resolved by discussion with the research team. We will use an iterative process to data charting using a piloted form. Findings will be collated into a narrative report.

ETHICS AND DISSEMINATION

Ethical approval is not required since data used are from publicly available secondary sources. Findings will be disseminated through peer-reviewed journals, conferences and stakeholder meetings. Further, findings will inform the next phases of a multistage research project aimed at understanding inequalities among patients with breast cancer.

Correlates of stigma for patients with breast cancer: a systematic review and meta-analysis

OBJECTIVE

This study was conducted to examine the factors associated with stigma in breast cancer women.

METHODS

PubMed, Embase, the Cochrane Library, Web of Science, and two Chinese electronic databases were electronically searched to identify eligible studies that reported the correlates of stigma for patients with breast cancer from inception to July 2022. Two researchers independently performed literature screening, data extraction, and risk of bias assessment. R4.1.1 software was used for statistical analysis.

RESULTS

Twenty articles including 4161 patients were included in the systematic review and meta-analysis. Results showed that breast cancer stigma was positively correlated with working status, type of surgery, resignation coping, depression, ambivalence over emotional expression, and delayed help-seeking behavior and negatively correlated with age, education, income, quality of life, social support, confrontation coping, psychological adaptation, self-efficacy, and self-esteem. Descriptive analysis showed that breast cancer stigma was positively correlated with intrusive thoughts, body image, anxiety, and self-perceived burden but negatively correlated with a sense of coherence, personal acceptance of the disease, sleep quality, cancer screening attendance and doctor's empathy.

CONCLUSION

Many demographic, disease-related, and psychosocial variables are related to breast cancer stigma. Our view can serve as a basis for health care professionals to develop health promotion and prevention strategies for patients with breast cancer.

Adherence to adjuvant endocrine therapy among White British and ethnic minority breast cancer survivors in the United Kingdom

OBJECTIVE

Around half of women do not take adjuvant endocrine therapy (AET) as prescribed. Research suggests that adherence rates vary across ethnic groups. This study compared AET adherences rates in White British women and women from minority ethnic groups in the United Kingdom.

METHODS

This is an observational study with 2001 breast cancer survivors recruited from outpatient clinics. Eligible women were diagnosed with primary breast cancer and prescribed AET within the last 3 years. Adherence was measured using the Medication Adherence Rating Scale. Eligible women were asked to complete a questionnaire pack that collected sociodemographic data such as age, relationship status and ethnicity. Independent samples t tests and χ² tests were used to compare White British women and women from minority ethnic groups on self-reported adherence to AET.

RESULTS

Of White British women, 27.8% were classed as non-adherent, compared to 44.4% of women from minority ethnic groups. A logistic regression controlling for relevant demographics indicated that women from minority ethnic groups had a significantly higher risk of non-adherence than women who were White British (odds ratio = 1.50, p = 0.03) CONCLUSION: Rates of non-adherence to AET are higher in women from minority ethnic groups, which may contribute towards racial disparities in breast cancer outcomes. Research with larger and more diverse samples is needed to explore this further and to investigate the psychosocial factors driving differences in adherence.

LGBTQ+ health and anaesthesia for obstetric and gynaecological procedures

PURPOSE OF REVIEW

People who self-identify as lesbian, gay, bisexual, transgender, queer, two-spirited and intersex (LGBTQ2SI) make up approximately 10% of the US population. Black, Native American and Latino/a/x communities are known to have a higher percentage of people who self-identify as LGBTQ2SI than white communities. Despite growing acceptance of LGBTQ2SI communities in the USA, these populations continue to experience health inequities. This review article will provide a narrative review of recent publications that discuss topics of LGBTQ2SI health and anaesthetic care during obstetric and gynaecological procedures.

RECENT FINDINGS

Of the articles reviewed for this study, there were four main themes that emerged: inclusion of LGBTQ2SI health topics in curriculum and provider training materials; social determinants of LGBTQ2SI reproductive and overall health; improving the quality and safety of perioperative care for LGBTQ2SI communities; and disparities in perinatal anaesthetic care for LGTBQ2SI communities.

SUMMARY

There are unique considerations when providing anaesthetic care for obstetric and gynaecological procedures to LGBTQ2SI communities. There is a limited, yet growing, body of literature exploring this aspect of perioperative and perinatal care. Researchers and clinicians must continue to pursue clinical research which seeks to improve the quality of care we provide all patients.
