Cancer Screening among immigrants living in urban and regional Australia: results from the 45 and up study

Palliative care symptoms and problems in a culturally and linguistically diverse population: large retrospective cohort study

OBJECTIVES

Migrant Australians with cancer have higher unmet needs and poorer health-related quality of life. Less is known about their palliative care experience. We aimed to assess comparative symptom distress and problem severity for culturally and linguistically diverse Australians with cancer in palliative care.

METHODS

This was a retrospective, consecutive cohort study using data from the Palliative Care Outcomes Collaboration, which routinely collects standardised symptom assessments nationally at point-of-care. Adults with a cancer diagnosis who died 01/01/2016-31/12/2019 were included. The presence/absence of patient-reported symptom distress and clinician-rated problem severity were compared between people who preferred English and people who preferred another language using logistic regression models. We also compared people who preferred English and the four most common non-English languages in the dataset: Chinese, Greek, Italian and Slavic.

RESULTS

A total of 53 964 people with cancer died within the study period, allowing analysis of 104 064 assessments. People preferring non-English languages were less likely to report symptoms (pain: OR=0.89 (0.84 to 0.94); all other symptoms except fatigue OR<1 and CIs did not contain 1). Except for family/carer problems (OR=1.24 (1.12 to 1.31)), linguistically diverse people were less likely to report problems. Variation was seen between non-English language groups.

CONCLUSIONS

We did not find evidence of comparatively worse symptom distress or problem severity for nearly all scores for culturally and linguistically diverse Australians. Better symptom management or differential reporting may explain this. It is important to examine this further, including assessing differences within cultural and linguistic groups to ensure the delivery of high-quality palliative care.

Incidence profile of four major cancers among migrants in Australia, 2005-2014

PURPOSE

To compare the incidence profile of four major cancers in Australia by place of birth.

METHODS

In this retrospective population-based cohort study, the analysis included 548,851 residents diagnosed with primary colorectum, lung, female breast, or prostate cancer during 2005-2014. Incidence rate ratio (IRR) and 95% confidence intervals (CI) were calculated for migrant groups relative to Australian-born.

RESULTS

Compared with Australian-born residents, most migrant groups had significantly lower incidence rates for cancers of the colorectum, breast and prostate. The lowest rates of colorectal cancer were among males born in Central America (IRR = 0.46, 95% CI 0.29-0.74) and females born in Central Asia (IRR = 0.38, 95% CI 0.23-0.64). Males born in North-East Asia had the lowest rates of prostate cancer (IRR = 0.40, 95% CI 0.38-0.43) and females born in Central Asia had the lowest rates of breast cancer (IRR = 0.55, 95% CI 0.43-0.70). For lung cancer, several migrant groups had higher rates than Australian-born residents, with the highest rates among those from Melanesia (males IRR = 1.39, 95% CI 1.10-1.76; females IRR = 1.40, 95% CI 1.10-1.78).

CONCLUSIONS

This study describes cancer patterns among Australian migrants, which are potentially helpful in understanding the etiology of these cancers and guiding the implementation of culturally sensitive and safe prevention measures. The lower incidence rates observed for most migrant groups may be maintained with continued emphasis on supporting communities to minimize modifiable risk factors such as smoking and alcohol consumption and participation in organized cancer screening programmes. Additionally, culturally sensitive tobacco control measures should be targeted to migrant communities with high lung cancer incidence rates.

Men of refugee and migrant backgrounds in Australia: a scoping review of sexual and reproductive health research

Australia's National Men's Health Strategy 2020-2030 identifies refugee and migrant men from culturally and lingustically diverse backgrounds as priority groups for sexual and reproductive health (SRH) interventions. The paucity of SRH research focusing on refugee and migrant men is a significant gap to advance men's health and policy. Hence, this review aimed to synthesise the available evidence on refugee and migrant men's SRH needs, understandingsand experiences of accessing services after resettlement in Australia. A systematic search of peer reviewed literature in PubMed, Scopus, and PsyInfo was made. A World Health Organization framework for operationalising sexual health and its relationship with reproductive health was used to map the identified studies. The socio-ecological framework was applied to thematically synthesise data extracted from individual studies and identify factors that influence the SRH of refugee and migrant men. We included 38 papers in the review. The majority of sexual health studies (16) were about sexually transmitted infections (STIs), mainly HIV (12), followed by sexual health education and information (5) and sexual functioning (3). Reproductive health studies focused on contraceptive counselling and provision (3), antenatal, intrapartum and postnatal care (1) and safe abortion care (1). Several factors influenced refugee and migrant men's SRH, including a lack of access to SRH information, language barriers and stigma. We found that SRH literature on refugee and migrant men focuses on STIs, meaning other areas of SRH are poorly understood. We identified key gaps in research on experiences of, and access to, comprehensive SRH care.

Breast cancer screening practices and associated factors among Chinese-Australian women living in Sydney: A cross-sectional survey study

This study aimed to investigate breast cancer screening practices and associated factors among Chinese‐Australian women. A cross‐sectional quantitative survey method including convenience and snowball sampling was used to recruit 115 Chinese‐Australian women living in Sydney, using a self‐administered survey. In all, 69.8% of participants reported recent clinical breast examinations and 73.3% had mammograms. Age, religion, employment status, and length of residence were associated with having a clinical breast examination. Income was related to having a mammogram. Associations between knowledge of breast cancer, cancer‐related beliefs, and screening participation were found. Length of residence in Australia was the strongest predictor of having a clinical breast examination and mammogram. The most common barrier to mammography was if women felt that doctors did not recommend it to them. Chinese‐Australian women need to be educated about awareness of their usual breast health to be aware of any changes, especially if women are not eligible for mammography or have difficulty in accessing health services. Tailored programs, improving screening experiences, and minimizing perceived barriers are needed to promote early detection of breast cancer among Chinese–Australian women.

Exploring the influence of rural residence on uptake of organized cancer screening - A systematic review of international literature

Lower screening uptake could impact cancer survival in rural areas. This systematic review sought studies comparing rural/urban uptake of colorectal, cervical and breast cancer screening in high income countries. Relevant studies (n = 50) were identified systematically by searching Medline, EMBASE and CINAHL. Narrative synthesis found that screening uptake for all three cancers was generally lower in rural areas. In meta-analysis, colorectal cancer screening uptake (OR 0.66, 95 % CI = 0.50-0.87, I² = 85 %) was significantly lower for rural dwellers than their urban counterparts. The meta-analysis found no relationship between uptake of breast cancer screening and rural versus urban residency (OR 0.93, 95 % CI = 0.80-1.09, I² = 86 %). However, it is important to note the limitation of the significant statistical heterogeneity found which demonstrates the lack of consistency between the few studies eligible for inclusion in the meta-analyses. Cancer screening uptake is apparently lower for rural dwellers which may contribute to poorer survival. National screening programmes should consider geography in planning.

Beyond language: Motivators and barriers to breast cancer screening among Korean-speaking women in Sydney Metropolitan, Australia

BACKGROUND

There are persistent disparities in breast screening participation rates between Australian-born women and women from culturally and linguistically diverse (CALD) backgrounds. Cancer Institute NSW statistics from 2015 show Korean speaking women had the second lowest breast screening participation rates when compared across all language groups.

OBJECTIVE

The study aimed to gain a better understanding of the motivators and barriers associated with participation in breast cancer screening among women from a Korean background living in the Sydney metropolitan area.

METHODS

Semi-structured individual interviews (n = 32) and small focus groups (n = 28) were conducted. Data from interviews and focus group discussions were analysed using thematic analysis.

RESULTS

The findings highlight the barriers to access breast screening services extend beyond language to include perception, a lack of knowledge and understanding of the services offered, unfamiliarity with the Australian healthcare system and distrust in breast screening services.

CONCLUSION

Supporting Korean women to understand and navigate the Australian healthcare system plays an important role in increasing breast screening participation rates. Key strategies to provide this support include the delivery of culturally sensitive health promotion and community engagement as well as the provision of translated health information.

Cervical Cancer Screening Among Immigrant Women Residing in Australia: A Systematic Review

Since the introduction of systematic population-based cervical cancer screening in Australia in 1991, age-standardized incidence of cervical cancer has halved. Given recent advances in human papillomavirus (HPV) vaccination and screening, cervical cancer may be eliminated nationally within 20 years. However, immigrant women are not equitably reached by screening efforts. This study systematically reviewed evidence on cervical cancer screening practices among immigrant women in Australia. A systematic search of MEDLINE, Embase, PubMed, CINAHL, and PsycINFO and gray literature for English language studies published till March 1, 2019, was conducted. Observational and qualitative studies evaluating cervical cancer screening awareness and participation of immigrant women were screened. Of 125 potentially relevant studies, 25 were eligible: 16 quantitative (4 cohort, 12 cross-sectional), 6 qualitative, and 3 mixed-methods studies. Quantitative studies indicated 1% to 16% lower screening rates among migrant women compared with Australian-born women, with participation of South Asian women being significantly lower (odds ratio = 0.54, 95% confidence interval = 0.48-0.61). Qualitative studies illustrated factors affecting women's willingness to participate in screening, including insufficient knowledge, low-risk perception, and unavailability of a female health professionals being key barriers. Future studies should focus on South Asian women, due to recent increase in their immigration.

Barriers and facilitators to cervical screening for Filipino women – a narrative literature review

Purpose

Mortality rates of cervical cancer are high amongst Filipino women; however, uptake of cervical screening is low. The purpose of this paper is to identify known barriers and facilitators to cervical screening for Filipino migrant women.

Design/methodology/approach

A systematic approach was adopted for the search, data extraction, critical appraisal and synthesis processes of this review. Eight electronic databases were searched. Studies published in peer review journals in English between 1995 and 2019 were reviewed.

Findings

In total, 20 relevant studies were identified. Studies were heterogeneous in design and focus and mostly conducted in the USA. A complex multifactorial picture of barriers to cervical screening was identified, which included: demographic, cognitive, access, health-care provider and cultural factors. None of the studies incorporated all factors.

Practical implications

This review demonstrates the complexity and multifactorial characteristic of cervical screening for Filipino migrant women. To increase uptake of screening, barriers to cervical screening for Filipino migrant women need to be fully understood. Future research should be conducted in different locations, focussing on multiple factors.

Originality/value

Aggregation of barriers and facilitators for Asian women combined tends to ignore cultural differences between groups. This review synthesises the existing but scarce literature to identify known barriers and facilitators to cervical screening for this specific population of Filipino migrant women.

Pathways to a cancer-free future: a protocol for modelled evaluations to minimise the future burden of colorectal cancer in Australia

INTRODUCTION

With almost 50% of cases preventable and the Australian National Bowel Cancer Screening Program in place, colorectal cancer (CRC) is a prime candidate for investment to reduce the cancer burden. The challenge is determining effective ways to reduce morbidity and mortality and their implementation through policy and practice. Pathways-Bowel is a multistage programme that aims to identify best-value investment in CRC control by integrating expert and end-user engagement; relevant evidence; modelled interventions to guide future investment; and policy-driven implementation of interventions using evidence-based methods. METHODS AND ANALYSIS: Pathways-Bowel is an iterative work programme incorporating a calibrated and validated CRC natural history model for Australia (Policy1-Bowel) and assessing the health and cost outcomes and resource use of targeted interventions. Experts help identify and prioritise modelled evaluations of changing trends and interventions and critically assess results to advise on their real-world applicability. Where appropriate the results are used to support public policy change and make the case for optimal investment in specific CRC control interventions. Fourteen high-priority evaluations have been modelled or planned, including evaluations of CRC outcomes from the changing prevalence of modifiable exposures, including smoking and body fatness; potential benefits of daily aspirin intake as chemoprevention; increasing CRC incidence in people aged <50 years; increasing screening participation in the general and Aboriginal and Torres Strait Islander populations; alternative screening technologies and modalities; and changes to follow-up surveillance protocols. Pathways-Bowel is a unique, comprehensive approach to evaluating CRC control; no prior body of work has assessed the relative benefits of a variety of interventions across CRC development and progression to produce a list of best-value investments.

ETHICS AND DISSEMINATION

Ethics approval was not required as human participants were not involved. Findings are reported in a series of papers in peer-reviewed journals and presented at fora to engage the community and policymakers.

An initial melanoma diagnosis may increase the subsequent risk of prostate cancer: Results from the New South Wales Cancer Registry

Emerging evidence suggests that a diagnosis of cutaneous melanoma (CM) may be associated with prostate cancer (PC) incidence. We examined if the incidence of CM was associated with an increased subsequent risk of PC. We used data from the New South Wales Cancer Registry for all CM and PC cases diagnosed between January 1972 and December 2008. We calculated the age standardized incidence ratio (SIR) and 95% confidence intervals (95% CI) for PC incidence following a CM diagnosis, applying age- and calendar- specific rates to the appropriate person years at risk. We determined rate ratio (RR) and 95% CI of PC incidence according to specified socio-demographic categories and disease related characteristics, using a negative binomial model. There were 143,594 men diagnosed with PC or CM in the study period and of these 101,198 and 42,396 were diagnosed with PC and CM, respectively, as first primary cancers. Risk of PC incidence increased following CM diagnosis (n = 2,114; SIR = 1.25; 95% CI:1.20.8-1.31: p < 0.0001), with the increased risk apparent in men diagnosed with localised CM (n = 1,862;SIR = 1.26; 95% CI:1.20-1.32). CM diagnosis increased the subsequent risk of PC incidence. This raises the potential for future PC risk to be discussed with newly diagnosed males with CM.

Variations in outcomes by residential location for women with breast cancer: a systematic review

OBJECTIVES

To systematically assess the evidence for variations in outcomes at each step along the breast cancer continuum of care for Australian women by residential location.

DESIGN

Systematic review.

METHODS

Systematic searches of peer-reviewed articles in English published from 1 January 1990 to 24 November 2017 using PubMed, EMBASE, CINAHL and Informit databases. Inclusion criteria were: population was adult female patients with breast cancer; Australian setting; outcome measure was survival, patient or tumour characteristics, screening rates or frequencies, clinical management, patterns of initial care or post-treatment follow-up with analysis by residential location or studies involving non-metropolitan women only. Included studies were critically appraised using a modified Newcastle-Ottawa Scale.

RESULTS

Seventy-four quantitative studies met the inclusion criteria. Around 59% were considered high quality, 34% moderate and 7% low. No eligible studies examining treatment choices or post-treatment follow-up were identified. Non-metropolitan women consistently had poorer survival, with most of this differential being attributed to more advanced disease at diagnosis, treatment-related factors and socioeconomic disadvantage. Compared with metropolitan women, non-metropolitan women were more likely to live in disadvantaged areas and had differing clinical management and patterns of care. However, findings regarding geographical variations in tumour characteristics or diagnostic outcomes were inconsistent.

CONCLUSIONS

A general pattern of poorer survival and variations in clinical management for Australian female patients with breast cancer from non-metropolitan areas was evident. However, the wide variability in data sources, measures, study quality, time periods and geographical classification made direct comparisons across studies challenging. The review highlighted the need to promote standardisation of geographical classifications and increased comparability of data systems. It also identified key gaps in the existing literature including a lack of studies on advanced breast cancer, geographical variations in treatment choices from the perspective of patients and post-treatment follow-up.

Lower attendance rates in immigrant versus non-immigrant women in the Norwegian Breast Cancer Screening Programme

Objective

The Norwegian Breast Cancer Screening Programme invites women aged 50–69 to biennial mammographic screening. Although 84% of invited women have attended at least once, attendance rates vary across the country. We investigated attendance rates among various immigrant groups compared with non-immigrants in the programme.

Methods

There were 4,053,691 invitations sent to 885,979 women between 1996 and 2015. Using individual level population-based data from the Cancer Registry and Statistics Norway, we examined percent attendance and calculated incidence rate ratios, comparing immigrants with non-immigrants, using Poisson regression, following women's first invitation to the programme and for ever having attended.

Results

Immigrant women had lower attendance rates than the rest of the population, both following the first invitation (53.1% versus 76.1%) and for ever having attended (66.9% versus 86.4%). Differences in attendance rates between non-immigrant and immigrant women were less pronounced, but still present, when adjusted for sociodemographic factors. We also identified differences in attendance between immigrant groups. Attendance increased with duration of residency in Norway. A subgroup analysis of migrants' daughters showed that 70.0% attended following the first invitation, while 82.3% had ever attended.

Conclusions

Immigrant women had lower breast cancer screening attendance rates. The rationale for immigrant women's non-attendance needs to be explored through further studies targeting women from various birth countries and regions.

Comparison of influenza vaccination coverage between immigrant and Australian-born adults

Australia has a large immigrant population but there are few data regarding whether influenza vaccine coverage in adults varies according to country of birth. We quantified and compared self-reported influenza vaccination coverage between Australian-born and immigrant residents aged ⩾49years enrolled in a large cohort (the 45 and Up Study), surveyed in 2012 and 2013. Estimated vaccine coverage was adjusted for age, sex and other factors known to be associated with vaccine uptake. Among 76,040 participants included in the analyses (mean age 66.2years), 21.6% were immigrants. In Australian-born adults aged 49-64 and 65+ years the age- and sex-adjusted estimates for influenza vaccination within the year prior to survey was 39.5% (95% CI 38.9-40.0) and 70.9% (70.4-71.5) respectively. The corresponding estimates in immigrants were significantly lower at 34.8% (33.7-35.8) and 64.4% (63.4-65.4) respectively. Among immigrants, coverage varied by region of birth, and was slightly lower among those who spoke a language other than English at home compared to those who only spoke English. Among immigrants there was no significant difference in coverage comparing those who migrated when they were children to those who migrated as adults and coverage did not differ significantly according to years lived in Australia. Programs to increase adult vaccination coverage should consider the needs of immigrants.

Quantifying disparities in cancer incidence and mortality of Australian residents of New South Wales (NSW) by place of birth: an ecological study

Background

In 2013, about 32 % of the Australian population over 15 years of age was born overseas. Previous cancer-related immigrant health studies identified differences in mortality and incidence between immigrants and Australian-born people. To identify groups that may require targeted interventions, we describe by region of birth: 1. the highest cancer incidence and mortality rates for NSW residents, Australia’s most populous state; and 2. mortality to incidence ratios (MIR) for all cancers.

Methods

Cancer incidence and mortality data were obtained from NSW residents for 2004–2008 (averaged) by sex, region of birth and 10 year age groups. Age standardised incidence and mortality rates were calculated with 95 % confidence intervals (per 100,000), using the world standard population. In the place of 5-year survival rates, we used age standardised MIRs (=M/I) as a simple proxy indicator of cancer survival.

Results

All-cancer incidence only exceeded Australian born people (308.5) for New Zealand born (322). The highest reported incidence rates for cancers from all regions were prostate and breast cancers. All-cancer mortality exceeded Australian-born (105.3) in people born in Western Europe (110.9), Oceania (108.2) and UK and Ireland (106.4). For Australian-born residents, the MIR was 34 cancer deaths per 100 cases compared to residents from Central Europe at 38 deaths per 100 cases and lowest at 28 deaths per 100 cases for residents from Central and Southern Asia.

Conclusion

Some disparities between Australian-born NSW residents and immigrants were identified in prostate, breast and lung cancer mortality rates. While on average most immigrant groups have similar cancer characteristics for the top cancers, areas for improvement to inform strategies to alleviate cancer disparities are required. This analysis suggests that NSW residents could benefit from specific prevention programmes on healthy eating and smoking cessation, especially people from Central Europe, UK and Ireland and Western Europe. Rising immigration rates encourage us to continue to address the areas indicated for improvement.
