Breast and Colorectal Cancer Screening Barriers Among Immigrants and Refugees: A Mixed-Methods Study at Three Community Health Centres in Toronto, Canada

Exploring equity in cancer treatment, survivorship, and service utilisation for culturally and linguistically diverse migrant populations living in Queensland, Australia: a retrospective cohort study

BACKGROUND

There is strong international evidence documenting inequities in cancer care for migrant populations. In Australia, there is limited information regarding cancer equity for Culturally and Linguistically Diverse (CALD) migrant populations, defined in this study as migrants born in a country or region where English is not the primary language. This study sought to quantify and compare cancer treatment, survivorship, and service utilisation measures between CALD migrant and Australian born cancer populations.

METHODS

A retrospective cohort study was conducted utilising electronic medical records at a major, tertiary hospital. Inpatient and outpatient encounters were assessed for all individuals diagnosed with a solid tumour malignancy in the year 2016 and followed for a total of five years. Individuals were screened for inclusion in the CALD migrant or Australian born cohort. Bivariate analysis and multivariate logistic regression were used to compare treatment, survivorship, and service utilisation measures. Sociodemographic measures included age, sex, post code, employment, region of birth and marital status.

RESULTS

A total of 523 individuals were included, with 117 (22%) in the CALD migrant cohort and 406 (78%) in the Australian-born cohort. CALD migrants displayed a statistically significant difference in time from diagnosis to commencement of first treatment for radiation (P = 0.03) and surgery (P = 0.02) and had 16.6 times higher odds of declining recommended chemotherapy than those born in Australia (P = 0.00). Survivorship indicators favoured CALD migrants in mean time from diagnosis to death, however their odds of experiencing disease progression during the study period were 1.6 times higher than those born in Australia (P = 0.04). Service utilisation measures displayed that CALD migrants exhibited higher numbers of unplanned admissions (P = < 0.00), longer cumulative length of those admissions (P = < 0.00) and higher failure to attend scheduled appointments (P = < 0.00).

CONCLUSION

This novel study has produced valuable findings in the areas of treatment, survivorship, and service utilisation for a neglected population in cancer research. The differences identified suggest potential issues of institutional inaccessibility. Future research is needed to examine the clinical impacts of these health differences in the field of cancer care, including the social and institutional determinants of influence.

Barriers to Screening At-risk Populations in Canada

Cancer screening is invaluable for early detection of disease, including for breast and lung cancer. Through early detection, cancer treatment can be commenced prior to the development of advanced stage disease, significantly reducing morbidity and mortality. However, eligible patients may face barriers when accessing screening services, and some groups may be more disproportionately affected than others. This review aims to describe some of the most prominent barriers that at-risk populations may face when accessing image-based cancer screening services in Canada. Characterizing these barriers would be helpful in determining the best strategies to increase uptake to these screening services and, consequently, improve health equity.

Barriers to cancer treatment and care for people experiencing structural vulnerability: a secondary analysis of ethnographic data

BACKGROUND

A key pillar of Canada's healthcare system is universal access, yet significant barriers to cancer services remain for people impacted by structural vulnerability (e.g., poverty, homelessness, racism). For this reason, cancer is diagnosed at a later stage, resulting in worse patient outcomes, a reduced quality of life, and at a higher cost to the healthcare system. Those who face significant barriers to access are under-represented in cancer control services Consequently, these inequities result in people dying from cancers that are highly treatable and preventable, however; little is known about their treatment and care course. The aim of this study was to explore barriers to accessing cancer treatment among people experiencing structural vulnerability within a Canadian context.

METHODS

We conducted a secondary analysis of ethnographic data informed by critical theoretical perspectives of equity and social justice. The original research draws from 30 months of repeated interviews (n = 147) and 300 h of observational fieldwork with people experiencing health and social inequities at the end-of-life, their support persons, and service providers.

RESULTS

Our analysis identified four themes presenting as 'modifiable' barriers to inequitable access to cancer treatment: (1) housing as a key determinant for cancer treatment (2) impact of lower health literacy (3) addressing social care needs is a pre-requisite for treatment (4) intersecting and compounding barriers reinforce exclusion from cancer care. These inter-related themes point to how people impacted by health and social inequities are at times 'dropped' out of the cancer system and therefore unable to access cancer treatment.

CONCLUSION

Findings make visible the contextual and structural factors contributing to inequitable access to cancer treatment within a publically funded healthcare system. Identifying people who experience structural vulnerability, and approaches to delivering cancer services that are explicitly equity-oriented are urgently needed.

Heterogeneity in the Utilization of Fecal Occult Blood Testing and Colonoscopy among Migrants and Non-Migrants in Austria: Results of the Austrian Health Interview Survey

Many European studies report lower participation in colorectal cancer screening among migrants than non-migrants. A major limitation of these studies is that usually, the heterogeneity of migrants cannot be accounted for. The aim of this investigation was to examine differences in the utilization of fecal occult blood testing and colonoscopy between non-migrants and the five largest migrant groups residing in Austria using data from the Austrian Health Interview Survey 2019. The two outcomes were compared between non-migrants and migrants using multivariable logistic regression adjusted for socioeconomic and health variables. Migrants from a Yugoslav successor state (OR = 0.61; 95%-CI: 0.44–0.83), Turkish (OR = 0.35; 95%-CI: 0.22–0.55), Hungarian (OR = 0.37; 95%-CI: 0.16–0.82) and German migrants (OR = 0.70; 95%-CI: 0.51–0.98) were less likely to have used a fecal occult blood test compared to non-migrants. Participation in colonoscopy was lower among Turkish migrants (OR = 0.42; 95%-CI: 0.27–0.67) and migrants from a Yugoslav successor state (OR = 0.56; 95%-CI: 0.42–0.75) than among non-migrants. The findings are consistent with studies from other countries and highlight barriers migrants face in accessing the health care system. To address these barriers, the heterogeneity of the population must be taken into account when developing educational materials in order to promote informed decisions about whether or not to participate in colorectal cancer screening.

Participation in Colorectal Cancer Screening among Migrants and Non-Migrants in Germany: Results of a Population Survey

Colorectal cancer screening can contribute to reducing colorectal cancer incidence and mortality. Findings on disparities in the utilization of colorectal cancer screening between migrants and non-migrants have been inconsistent, with some studies reporting lower, and some higher utilization among migrants. The aim of the present study was to examine potential disparities in fecal occult blood testing and colonoscopy among migrants in Germany. Data from a population survey on 11,757 men and women aged ≥50 years is used. Using multivariable logistic regression, the utilization of fecal occult blood testing and colonoscopy was compared between non-migrants, migrants from EU countries and migrants from non-EU countries, adjusting for socio-economic factors and also taking into account intersectional differences by sex and age. The study shows that migrants from the EU (adjusted OR = 0.73; 95%-CI: 0.57, 0.94) and from non-EU countries (adjusted OR = 0.39; 95%-CI: 0.31, 0.50) were less likely to utilize fecal occult blood testing than non-migrants. No disparities for the use of colonoscopy were observed. The findings are in line with studies from other countries and can be indicative of different barriers migrants encounter in the health system. Adequate strategies taking into account the diversity of migrants are needed to support informed decision-making among this population group.

Colorectal Cancer Screening Challenges in the Recent Afghan Refugee Population: A Comprehensive Review Article

Colorectal cancer (CRC) is more prevalent in south-central Asian countries, particularly the Afghan population. Screening for CRC in the Afghan population has always been challenging, primarily due to the tribal and social cultures, lack of facilities, and lack of education. The United States (US) will soon face a significantly massive influx of Afghan refugees. It becomes imperative to initiate and implement effective measures regarding CRC screening in these refugee populations. The current review article aims to identify the most likely challenges faced for CRC screening in this Afghan refugee population in the US and address the possible measures to overcome these challenges.

Care in the Community: Opportunities to improve cancer screening uptake for people living with low income

Despite organized provincial cancer screening programs, people living with low income consistently have lower rates of screening in Ontario, Canada than their more socioeconomically advantaged peers. We previously published results of a two-phase, exploratory qualitative study involving both interviews and focus groups whose objective was to integrate knowledge of people living with low income on how to improve primary care strategies aimed at increasing cancer screening uptake. In the current paper, we report previously unpublished findings from that study that identify how taking a community outreach approach in primary care may lead to increased cancer screening uptake among people living with low income. Participants told us that they saw value in a community outreach approach to cancer screening. They recommended specific actionable approaches, in particular, mobile community-based screening and community information sessions, and recommended taking an ethno-specific lens depending on the communities being targeted. Participants expressed a desire for primary care providers to go out into the community to learn more about the whole patient, such as could be achieved with home visits, but they simultaneously believed that this may be challenging in urban settings and in the context of perceived physician shortages. Models of primary care that provide support to an entire local community and provide some of their services directly in that community may have a meaningful impact on cancer screening for socially marginalized groups.

Primary Care Continuity and Wait Times to Receiving Breast Cancer Chemotherapy: A Population-Based Retrospective Cohort Study Using CanIMPACT Data

(1) Background: Wait times to chemotherapy are associated with morbidity and mortality in breast cancer patients; however, it is unclear how primary care physician (PCP) continuity impacts these wait times, or whether this association is different in immigrants, who experience cancer care inequities. We assessed the association between PCP continuity and the contact-to-chemotherapy interval (wait time from when a patient first presents to healthcare to the first day of receiving breast cancer chemotherapy), with a specific look at the immigrant population. (2) Methods: Population-based, retrospective cohort study of women who were diagnosed with stage I–III breast cancer in Ontario who received surgery and adjuvant chemotherapy. We used quantile regression at the median and 90th percentile to quantify the effect of PCP continuity on the contact-to-chemotherapy interval, performing a separate analysis on the immigrant population. (3) Results: Among 12,781 breast cancer patients, including 1706 immigrants, the median contact-to-chemotherapy interval (126 days) was 3.21 days shorter (95% confidence interval (CI) 0.47–5.96) in symptom-detected patients with low PCP continuity, 10.68 days shorter (95% CI 5.36–16.00) in symptom-detected patients with no baseline PCP visits and 17.43 days longer (95% CI 0.90–34.76) in screen-detected immigrants with low PCP continuity compared to the same groups with high PCP continuity. (4) Conclusions: Higher PCP continuity was not associated with a change in the contact-to-chemotherapy interval for most of our study population, but was associated with a marginally longer interval in our symptom-detected population and a shorter contact-to-chemotherapy interval in screen-detected immigrants. This highlights the importance of PCP continuity among immigrants with positive screening results. Additionally, having no PCP visits at baseline was associated with a shorter contact-to-chemotherapy interval in symptom-detected patients.

Psychosocial Correlates of Experience and Intention to Receive Colorectal Cancer Screening: A Cross-Sectional Study Among East African Men in the U.S

Cancer screening is an important approach to reducing disease burden. The rate of colorectal cancer (CRC) screening among immigrants in the U.S. is very low. Our study's aim was to examine correlates of experience with, and intention to, receive CRC screening among East African men who were up-to-date (UTD) with CRC screening (n = 64, mean age 65) and those who had never been screened or were overdue for one (NOD; n = 47, mean age 60), compared on demographic characteristics, attitudes toward cancer, psychosocial stress, and health behaviors. UTD men had significantly less emotional concerns about cancer screening and experienced significantly greater distress and lower resiliency than NOD men. However, these results were attenuated after controlling for demographic confounders. Perceived risk, trust in the medical system, and PTSD symptoms were significantly associated with an intention to undertake CRC screening in the next 12 months. These results should be used to guide efforts toward increasing CRC screening rates among immigrant communities.

Equity across the cancer care continuum for culturally and linguistically diverse migrants living in Australia: a scoping review

International evidence suggests migrants experience inequitable access, outcomes and treatment quality across the cancer care continuum. There is currently limited research assessing equity across the cancer care continuum for culturally and linguistically diverse migrants living in Australia. A detailed protocol and search strategy were developed and used to identify all relevant literature, utilising the Joanna Briggs Institute Reviewer’s Manual. Systematic searching was conducted via multiple databases and identified studies were screened against pre-identified inclusion and exclusion criteria. 71 studies met the inclusion criteria for analysis. Most studies examined cancer detection via screening. Very few studies examined cancer prevention, diagnosis, treatment or palliative care. Most studies focused on patient-sided barriers to care and there was a paucity of information regarding institutional barriers to health. Cancer-related outcomes were seldom examined, and most studies were qualitative or behavioral analysis. Results highlighted significant communication issues spanning the cancer care continuum and a context of inadequate support for both patients and clinicians. There is a demonstrable need to examine equity in access and outcomes for culturally and linguistically diverse cancer populations. This requires the identification of cancer-related disparities and an examination of institutional barriers to care. Through addressing this dearth of information, future research and health policy can support the operationalisation of health equity.

Disparities in Cancer Care: The Example of Sarcoma-In Search of Solutions for a Global Issue

Disparities in health care have an adverse effect on the outcome of disadvantaged patients with cancer. Patients may be at a disadvantage because of geographic isolation; insurance status; or racial, ethnic, or other factors. In this article, we examine how disparities affect the care of patients with sarcoma in the United States, Canada, and the Asia-Pacific region. Because of the rarity of sarcomas and their challenging diagnosis and complex treatment patterns, some professional or national guidelines stipulate that patients with sarcoma should be treated at centers of expertise by multidisciplinary teams. This recommendation, based on published evidence, is not always applicable because of various sociopolitical or patient-related factors. We are proposing solutions to overcome these obstacles in a practical and patient-centered way while acknowledging that disparities exist among countries as well as within any country.

Racial Disparities in Anal Cancer Screening Among Men Living With HIV: Findings From a Clinical Cohort Study

BACKGROUND

Our objective was to quantify the extent of anal cancer screening among men receiving HIV specialty care in Ontario, Canada, and evaluate factors associated with screening.

SETTING

Cross-sectional questionnaire within a multisite clinical HIV cohort.

METHODS

A questionnaire assessing knowledge and experience with human papillomavirus-associated diseases and their prevention was administered in 2016-2017 to 1677 men in the Ontario HIV Treatment Network Cohort Study. We used logistic regression to identify factors associated with having discussed screening with a health care provider and self-reported receipt of screening [digital anal rectal examinations (DARE); anal cytology or anoscopy]. Results reported as adjusted odds ratios (aORs) with 95% confidence intervals (CIs).

RESULTS

Forty percent of men reported ever having had anal cytology/anoscopy, and 70% had ever had DARE. After accounting for differences in age, sexual orientation, years since HIV diagnosis, previous diagnosis with AIDS, knowing someone with human papillomavirus-associated cancer, comfort discussing anal health, education, and income, the proportion screened differed by self-identified race. Compared with white men, Asian men were less likely to have discussed screening with a health care provider (aOR = 0.48; 95% CI: 0.29 to 0.80) or to have been screened by DARE (aOR = 0.27; 95% CI: 0.17 to 0.44) or anal cytology/anoscopy (aOR = 0.51; 95% CI: 0.31 to 0.83), and African, Caribbean, or black men (aOR = 0.47; 95% CI: 0.31 to 0.70) were less likely to have had DARE. Results were consistent when restricting the analyses to gay, bisexual, and other men who have sex with men.

CONCLUSION

Our findings highlight the potential for disparities in anal cancer screening that need to be considered when developing guidelines and screening programs to reduce the burden of anal cancer among men living with HIV and ensure health equity.

Social inequalities in breast cancer screening: evaluating written communications with immigrant Haitian women in Montreal

Background

The province of Quebec (Canada) has implemented a breast cancer screening program to diagnose this cancer at an early stage. The strategy is to refer women 50 to 69 years old for a mammogram every two years by sending an invitation letter that acts as a prescription. Ninety per cent (90%) of deaths due to breast cancer occur in women aged 50 and over. Numerous studies have shown social inequalities in health for most diseases. With breast cancer, a significant paradox arises: its incidence is lower among disadvantaged women and yet, more of them die from this disease. The health care system might play a role in this inequality. The scientific literature documents the potential for creating such inequalities when prevention does not consider equity among social groups. Immigrant women are often disadvantaged. They die of breast cancer more than non-immigrants. Studies attribute this to late-stage diagnosis due to poor adherence to mammography screening programs.

Purpose of the study

The main objective of our research is to assess how Haitian immigrant women in Montreal are reached by the Quebec Breast Cancer Screening Program, and specifically how they perceive the mammogram referral letter sent by the program.

Methods

The study uses a two-step qualitative method: i) In-depth interviews with influential community workers to identify the most relevant issues; ii) Focus groups with disadvantaged women from Montreal’s Haitian community.

Results

A mammogram referral letter from the Breast Cancer Screening Program may be a barrier to compliance with mammography by underprivileged Haitian women in Montreal. This might be attributable to a low level of literacy, poor knowledge of the disease, and lack of financial resources.

Conclusion

Barriers may be underestimated in underprivileged immigrant and non-immigrant communities. A preventive strategy must be adapted to different sub-groups and must also take into account lower literacy levels. To increase mammography uptake, it is crucial that the benefits of prevention be clearly identified and described in understandable terms. Finally, economic access to follow-up measures should be considered.

Effect of Perceptual Stress Reduction Control Intervention on the Level of Symptoms in Breast Cancer at Different Time Points

Background

To investigate the effect of perceptual stress reduction control intervention on the level of symptomatic groups at different time points in breast cancer.

Methods

A total of 124 breast cancer patients were divided into intervention group and control group, 62 cases in each group. Perioperative nursing and chemotherapy nursing were given to the control group, and the intervention group was given the interventional stress reduction control intervention. The level of symptom clusters of different time points were compared between the two groups.

Results

The incidence and severity of myelosuppression in the intervention group were slightly lower than those in the control group. The adverse reactions of bone marrow suppression at T3 were much lower than those in the control group, and the differences were significant (P=0.003, P=0.043). The control group had higher incidence and more severe symptoms of nausea, vomiting and diarrhea than the intervention group (P=0.002, P=0.042). The symptoms of breast pain and swelling at T1 in the intervention group were significantly lower than those in the control group (P=0.000, P=0.000). There was no significant difference in breast symptoms between the two groups at T2 and T3 (p>0.05). At the time of T2 and T3 of chemotherapy, the health promotion behavior scores of the intervention group were higher than the control group, and the difference was statistically significant (P_T2=0.000, P_T3=0.000).

Conclusion

Perceptual stress reduction control intervention can effectively relieve bone marrow suppression, digestive tract discomfort and breast symptoms, and promote health promotion behavior.

Uptake of cancer screenings among a multiethnic refugee population in North Texas, 2014-2018

Background

Refugees are less likely than US born populations to receive cancer screenings. Building Bridges is a community health worker prevention program designed to increase refugee’s cancer screening uptake. The purpose of this cross sectional analysis was to assess differences in uptake of cervical, breast, liver, and colorectal screens across six cultural groups.

Methods

Data was abstracted in 2018 for this analysis. Participants were categorized into six cultural groups (Myanmar, Central Africa, Bhutan, Somalia, Arabic Speaking Countries, and Other) to assess differences in sociodemographic measures and screening uptake. Uptake proportions were calculated for each cancer type (cervical, breast, liver, and colon) among eligible participants, by gender and cultural group. Differences in uptake across groups were assessed using stratified analysis and logistic regression. Prevalence odds ratios (POR) and 95% confidence intervals (CIs) were calculated for each group to assess the association between screening completion and cultural group.

Findings

874 refugees were asked about cancer screening history. The majority of participants were either ‘never had been screened’ or ‘not up-to-date’ for every cancer screening. Among age eligible, 82% had no prior pap exam within the past 3 years, 81% had no prior mammogram within the past year, 69% didn’t know their Hepatitis B status and 87% never had a colon cancer screening. Overall, higher uptake of all types of cancer screenings was observed in Myanmar and Bhutanese groups, except colon cancer screening which was higher among Central African Region and Arabic Speaking participants.

Conclusion

Screening uptake varied by ethnic group and screening type. The program reached an under and never screened population, however, the proportion of refugees who received a cancer screening remained low compared to the US population. Diversity within refugee communities requires adaptation to specific cultural and linguistic needs to include new Americans in cancer elimination efforts.
