Abstract
Cancer prevention challenges in Ethiopia include limited community awareness and low uptake of screening, which are in part driven by a lack of culturally and linguistically relevant cancer education appropriate for the diverse indigenous communities of this never-colonized nation. In 2022, a comprehensive multi-media breast cancer (BC) awareness campaign was implemented, featuring local cancer experts and survivors, with community-based screening events in the towns of Adama and Mojo. The RE-AIM framework was used to evaluate and describe its reach, effectiveness, adoption, implementation, and maintenance. Educational pamphlets, videos, social media posts, and interviews were distributed in person and through local and national media networks, reaching tens of millions of people and resulting in 525 individuals screened, with one diagnosis of early-stage cancer. During the free screening events, an interview-administered survey of BC knowledge, attitudes, and screening practices was conducted to inform future cancer education for this population. Among 287 survey respondents, about half correctly identified swelling (46%) or changing nipples/discharge (48.4%) as signs of BC. Maintenance challenges include the lack of a national screening program. Educational resources and a mobile app, translated into the local language, encourage continued patient empowerment to perform breast self-exams. In the absence of established BC prevention programs, "pop-up" mobile screening events can be effective for mobilizing communities to get screened. The paper highlights challenges and lessons gleaned from this community-based BC awareness campaign and screening event to inform future cancer education initiatives in Ethiopia and similar resource-limited settings.

[PMID: 38378542 PMCID: PMC10877795 DOI: 10.1186/s12889-024-17842-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Accepted: 01/22/2024] [Indexed: 02/22/2024] Open
Abstract
INTRODUCTION Africa has one of the highest burdens of cervical cancer in the world. The unacceptably high incidence and mortality rates could be reduced through implementing a comprehensive approach to its prevention and control that includes screening, which however, is low in most low-and-middle-income countries. Hence, this systematic review aims at exploring factors that prevent women from utilising cervical cancer screening services in the region. METHODS A mixed method systematic review was conducted. A search was performed on PubMed (Medline), EMBASE, CINAHL (EBSCOHOST) and Scopus databases for articles published until May 2019 without time, language or study design limits. Two reviewers critically appraised the included studies independently using the standard quality assessment criteria for evaluating primary research papers. Results of the quantitative and mixed methods studies were transformed into qualitative data and synthesised using thematic analysis. RESULTS From a potential 2 365 studies, 24 from 11 countries met the eligibility criteria and were selected; eight qualitative, 13 quantitative, and three that used the mixed-method approach. The primary barriers were identified as poor access to screening services, lack of awareness and knowledge on cervical cancer and screening, and socio-cultural influences. Service providers perceived lack of skills, screening equipment and supplies, and staff shortages as the major barriers to the provision of screening services. CONCLUSION Barriers to cervical cancer screening in Africa are multifaceted and require a holistic approach that will address them concurrently at the health system, individual, interpersonal, community and structural levels. Political will complimented by stakeholder involvement is required in the development and implementation of strategies that will ensure acceptability, availability, accessibility, and affordability of screening to minimise barriers in accessing the service.

[PMID: 38359371 PMCID: PMC10881110 DOI: 10.1200/go.23.00035] [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: 03/06/2023] [Revised: 11/04/2023] [Accepted: 11/14/2023] [Indexed: 02/17/2024] Open
Abstract
PURPOSE Indigenous communities experience worse cancer outcomes compared with the general population partly because of lower cancer screening access. One-size-fits-all screening programs are unsuitable for reaching Indigenous communities. In this review, we summarize available evidence on the perspectives of these communities; with a view to informing the improvement of cancer screening services to achieve equitable access. METHODS We undertook a systematic review according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, using the databases MEDLINE, Scopus, PubMed, and Google Scholar. The search terms used were "Indigenous community or Indigenous communities," "cancer screening," and "facilitators, enablers, desires, or needs." Qualitative studies published up to the August 30, 2022 investigating the perspectives of Indigenous communities on factors encouraging screening participation were included in the study. The included studies were reviewed and analyzed inductively by two independent reviewers, and key themes regarding indigenous access to cancer screening were then extracted. RESULTS A total of 204 unique articles were identified from the search. The title and abstracts of these studies were screened, and 164 were excluded on the basis of the exclusion and inclusion criteria. The full texts of the remaining 40 studies were examined and 18 were included in the review. Four key themes were identified pertaining to culturally tailored education and information dissemination, community involvement, positive relationships with health care providers, and individual empowerment and autonomy. CONCLUSION Improvements, on the basis of the key themes identified from this review, must be made at all levels of the health care system to achieve equitable screening participation in Indigenous communities. However, we recommend an investigation into the perspectives of the local Indigenous communities before the initiation of cancer screening programs.

[PMID: 37575100 PMCID: PMC10412821 DOI: 10.3389/fpubh.2023.1112172] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 07/13/2023] [Indexed: 08/15/2023] Open
Abstract
Background The cancer screening rate in the working population is very low in China. Information-motivation-behavioral skills (IMB) model has been applied to elucidate screening behavior for various chronic diseases but has not been investigated in analyzing cancer screening behavior. This study aimed to examine factors influencing cancer screening behavior and their linkages based on the IMB model. Methods A cross-sectional study was conducted in Shanghai, China from August to October 2021. Data were obtained through an anonymous questionnaire. Predictive relationships between variables in the IMB model and cancer screening behavior were evaluated. Structural equation modeling (SEM) was constructed to demonstrate the utility of the IMB model. Results Among the 556 participants included in the analysis, 34.4% of participants had ever done a cancer screening. The construct validation analysis supported that the measure items included were acceptable. SEM found that knowledge of cancer warning signs and symptoms (β = 0.563, p < 0.001) and cancer screening behavioral skills (β = 0.264, p = 0.003) were related to participation in cancer screening, whereas cancer screening motivation was not directly influenced the participation in cancer screening (β = - 0.075, p = 0.372). Conclusion The cancer screening rate was found to be lower than expected in the working population. The IMB model could be used to make decisions in implementing behavioral interventions to participate in cancer screening among the Chinese working population. Enhancing the knowledge of cancer warning signs and symptoms and strengthening behavioral skills should be focused on to improve participation in cancer screening.

Abstract
INTRODUCTION Worldwide, colorectal cancer is a major public health issue. Despite the existence of screening programmes in many countries, global uptake remains low. This meta-ethnography aimed to analyse qualitative literature to explore attitudes towards colorectal cancer screening and reasons for non-participation in eligible people that do not participate when invited. METHODS Systematic searches were conducted in five databases in May 2021. Critical appraisal of included studies was performed using the CASP checklist for qualitative studies. FINDINGS Thirteen studies were included. Three main themes and eight sub-themes were developed across studies: (1) Differences in motivation, with non-participants expressing a lack of knowledge and varying levels of intention to participate but not feeling screening was personally necessary; (2) Active aversion to screening expressed by fear, discomfort, disgust or not wanting to know; and (3) Contextual barriers of the healthcare system such as practical constraints or poor relationships with healthcare professionals. CONCLUSION Findings suggest multiple pathways to non-participation including ambivalence, aversion to the process and consequences of screening or lack of support. Persuasive messages and prompts to action to target ambivalence, reassurance regarding the screening procedures to target negative reactions, and increased support from healthcare professionals may be beneficial in increasing screening uptake.

Abstract
BACKGROUND Current evidence on the psychological impact of screening and diagnosis of esophageal cancer (EC) is limited and unclear. METHODS This multicenter, population-based, prospective study was conducted in five high-incidence regions in China from 2017 to 2020. The screened participants were diagnosed as healthy, esophagitis, low-grade intraepithelial neoplasia (LGIN), high-grade intraepithelial neoplasia (HGIN), or EC based on pathological biopsy. The psychological impact of the screening was assessed by comparing anxiety and depression symptoms at baseline and follow-up. RESULTS A total of 1973 individuals were ultimately included, with an average follow-up of 22.2 months. The prevalence of anxiety and depression symptoms in screened population at baseline was 14.3% and 18.4%. The prevalence of anxiety and depression symptoms of screeners at follow-up declined (all p < 0.001). The anxiety (RR [95% CI]: 0.37 [0.30-0.46]) and depression (0.29 [0.24-0.36]) of screeners weakened over time, but the anxiety and depression symptoms was continuous for patients with HGIN and patients with EC. Compared with the participants classified as normal, the RRs(95% CI) of anxiety and depression symptoms were 2.20 (1.10-4.30) and 2.03 (1.07-3.86) for the patients with HGIN and 2.30 (0.82-6.20) and 3.79 (01.71-8.43) for the patients with EC. CONCLUSION The anxiety and depression symptoms of screeners weakened over time, except in patients with HGIN and EC, for whom it remained lasting and high. Psychological assistance and interventions are urgently needed for individuals who are ready for screening and for those diagnosed as having HGIN or EC.

Factors associated with cancer survival disparities among Aboriginal and Torres Strait Islander peoples compared with other Australians: A systematic review. Front Oncol 2022; 12:968400.

Abstract
Background While cancer survival among Aboriginal and Torres Strait Islander peoples has improved over time, they continue to experience poorer cancer survival than other Australians. Key drivers of these disparities are not well understood. This systematic review aimed to summarise existing evidence on Aboriginal and Torres Strait Islander cancer survival disparities and identify influential factors and potential solutions. Methods In accordance with PRISMA guidelines, multiple databases were systematically searched for English language peer-reviewed articles on cancer survival by Aboriginal and Torres Strait Islander status published from 1/1/2008 to 4/05/2022. Observational studies presenting adjusted survival measures in relation to potential causal factors for disparities were included. Articles were screened independently by two authors. Included studies were critically assessed using Joanna Briggs Institute tools. Results Thirty population-based and predominantly state-level studies were included. A consistent pattern of poorer unadjusted cancer survival for Aboriginal and Torres Strait Islander peoples was evident. Studies varied widely in the covariates adjusted for including a combination of socio-demographics, cancer stage, comorbidities, and treatment. Potential contributions of these factors varied by cancer type. For lung and female breast cancer, adjusting for treatment and comorbidities reduced the survival disparity, which, while still elevated was no longer statistically significant. This pattern was also evident for cervical cancer after adjustment for stage and treatment. However, most studies for all cancers combined, or colorectal cancer, reported that unexplained survival disparities remained after adjusting for various combinations of covariates. Conclusions While some of the poorer survival faced by Aboriginal and Torres Strait Islander cancer patients can be explained, substantial disparities likely to be related to Aboriginal determinants, remain. It is imperative that future research consider innovative study designs and strength-based approaches to better understand cancer survival for Aboriginal and Torres Strait Islander peoples and to inform evidence-based action.

Abstract
Human papillomavirus (HPV) self-sampling offers a cervical cancer (CC) screening alternative that can address certain barriers to the Papanicolaou test. As part of a larger community-based participatory project in Nunavik, Northern Québec, we travelled to two communities to gather perspectives from Inuit women and healthcare professionals (HCPs) on CC screening services and the possible implementation of HPV self-sampling. We held 10 group discussions with 28 Inuit women and 10 semi-structured interviews with 20 HCPs. The thematic analysis extracted themes reflecting one barrier and seven facilitators to accessing CC screening and the implementation of HPV self-sampling in Nunavik. Themes included, though not limited to, language and communication in health settings, access to culturally responsive educational resources on CC, and the noninvasive nature of HPV self-sampling. This study may serve to contribute to the co-development of a strategy for implementation that is designed according to the needs and priorities of the communities.

Abstract
Screening is an essential prevention practice for a number of health conditions. However, screening coverage remains generally low. Studies that investigate determinants of screening participation are becoming more common, but oftentimes investigate screening for health conditions in an individualized rather than integrated fashion. In routine clinical practice, however, healthcare professionals are often confronted with situations in which several screening procedures are recommended for the same patient. The consideration of their common determinants may support a more integrated screening approach. The objectives of this umbrella review were therefore to examine: 1) the determinants (barriers and facilitators) that have been identified in relation to recommended health screening procedures; and 2) the modifiable determinants (in primary care) common across health conditions or specific to individual procedures. Results were presented through a narrative synthesis. PubMed, PsycInfo and Cochrane were searched up to January 2022. Systematic reviews reporting determinants of participation in health screening procedures with grade A or B recommendation according to the US Preventive Services Task Force were included. A total of 85 systematic reviews were included, most which contained both qualitative and quantitative studies on determinants that describe individual factors (961 occurrences), social factors (113 occurrences, healthcare professional factors (149 occurrences), health system factors (105 occurrences) and screening procedure factors (99 occurrences). The most studied screening procedures concerned cervical cancer/human papillomavirus (n = 33), breast cancer (n = 28), colorectal cancer (n = 25) and the human immunodeficiency virus (n = 12). Other conditions have been under-studied (e.g. cardiovascular problems, lung cancer, syphilis). The individual domain, including determinants such as knowledge, beliefs and emotions, was the most covered across health conditions. Healthcare professional's recommendations and the quality of patient-provider communication were identified to have a strong influence on screening participation in most conditions. The other three domains included determinants which were more specific to a condition or a population. Various determinants modifiable in primary care were found in the individual domain and in the health system, healthcare professional and screening procedure domains. Quality was assessed as low for most systematic reviews included. The identification of various modifiable determinants common across conditions highlights the potential of an integrated screening participation approach. Interventions may address common determinants in a broader person-centred framework within which tailoring to specific procedures or populations can be considered. This approach needs to be explored in intervention studies. The systematic review registration is PROSPERO CRD42019126709.

Abstract
Objective To determine if masculinity barriers to medical care and the death from colorectal cancer (CRC) of actor Chadwick Boseman (The Black Panther) influenced CRC early-detection screening intent among unscreened American Indian/Alaska Native (AIAN) and Non-Hispanic-Black (Black) men compared with Non-Hispanic-White (White) men. Methods Using a consumer-panel, we surveyed U.S. men aged 18-75 years (N = 895) using the 24-item Masculinity Barriers to Medical Care (MBMC) scale. We calculated the median score to create binary exposures to evaluate associations with CRC screening intent and conducted multivariable logistic regression to evaluate independent associations stratified by race/ethnicity. Results Overall, Black respondents were most likely to have a high MBMC score (55%) compared to White (44%) and AIAN (51%) men (p = 0.043). AIAN men were least likely to report CRC screening intent (51.1%) compared with Black (68%) and White men (64%) (p < 0.001). Black men who reported the recent death of Chadwick Boseman increased their awareness of CRC were more likely (78%) to report intention to screen for CRC compared to those who did not (56%) (p < 0.001). Black men who exhibited more masculinity-related barriers to care were more likely to intend to screen for CRC (OR: 1.76, 95% CI: 0.98-3.16) than their counterparts, as were Black men who reported no impact of Boseman's death on their CRC awareness (aOR: 2.96, 95% CI: 1.13-7.67). Conversely, among AIAN men, those who exhibited more masculinity-related barriers to care were less likely to have CRC screening intent (aOR: 0.47, 95% CI: 0.27-0.82) compared with their counterparts. Conclusions Masculinity barriers to medical care play a significant role in intention to screen for CRC. While Black men were most likely to state that The Black Panther's death increased their awareness of CRC, it did not appear to modify the role of masculine barriers in CRC screening intention as expected. Further research is warranted to better understand how masculine barriers combined with celebrity-driven health-promotion interventions influence the uptake of early-detection screening for CRC. Impact Our study provides formative data to develop behavioral interventions focused on improving CRC screening completion among diverse men.

Abstract
There are long-standing debates about the benefits of prostate cancer screening. Conflicting trial results and inconsistent recommendations regarding prostate cancer screening in clinical guidelines highlight the importance of patient factors that influence decision making in prostate cancer screening. Attitude is an important factor associated with cancer screening. However, attitudes toward prostate cancer screening among Chinese men are still poorly understood. The objective of the study was to evaluate attitudes toward prostate cancer screening and their association with prostate cancer screening intention among Chinese men. In this community-based study, 340 males were randomly recruited. Three distinct concepts related to prostate cancer screening attitudes were evaluated, including perceived consequences of screening, moral obligation, and anticipated regret. The intention to have prostate cancer screening was asked. Only 5.00% of the study participants had prostate cancer screening before, while 69.71% have an intention to undergo screening in the future. Participants with a high level of anticipated regret also had a high likelihood to have screening in the future, with an adjusted odds ratio (aOR) of 1.82. Participants who had favorable attitudes toward the consequence of participating in prostate cancer screening had a high likelihood to undergo screening, with an aOR of 1.22. Participants who were more concerned about pain and invasion of privacy were less likely to have an intention to have prostate cancer screening, with aORs of 0.53 and 0.57, respectively. To enhance screening intention, public health programs should include components related to anticipated regrets and perceived consequences.

Abstract
BACKGROUND Breast cancer is the most commonly diagnosed cancer in Aboriginal and/or Torres Strait Islander women. When compared to other Australians, Aboriginal and/or Torres Strait Islander women have a higher breast cancer mortality rate. This systematic literature review examined disparities in breast cancer surgical access and outcomes for Aboriginal and/or Torres Strait Islander women. METHODS This systematic literature review, following the PRISMA guidelines, compared measures of breast cancer surgical care for Aboriginal and/or Torres Strait Islander people and other Australians. RESULTS The 13 included studies were largely state-based retrospective reviews of data collected prior to the year 2012. Eight studies reported more advanced breast cancer presentation among Aboriginal and/or Torres Strait Islander women. Despite the increased distance to a multidisciplinary, specialist team, there were no disparities in seeing a surgeon, or in the time from diagnosis to surgical treatment. Two studies reported disparities in the receipt of surgery and two reported no variations. Three studies reported disparities in the receipt of mastectomy versus breast conserving surgery, whilst four studies reported no variations. No studies examined postoperative surgical outcomes. CONCLUSIONS Aboriginal and/or Torres Strait Islander women present with more advanced breast cancer. There may be disparities in the receipt of surgery and the type of surgery. However, the metrics tested were not related to optimal care guidelines, and the databases utilised contain limited data on individual factors contributing to surgical care decisions. It is therefore difficult to determine whether the reported differences in the receipt of surgical care reflect disparate or appropriate care.

Abstract
Despite evidence that breast cancer screening effectively diagnoses and treats cancer through early detection, mammography use remains low in Taiwan. We applied the health belief model (HBM) and the knowledge-attitude-behavior (KAB) model as theoretical frameworks to examine factors associated with mammography uptake among women aged 45-69 years in Taiwan. A cross-sectional survey January-July 2018 was conducted of women aged 45-69 years in five southern Taiwan health institutions. Survey questionnaires included demographics, HBM constructs, and health knowledge regarding breast cancer and screening. Multivariable logistic regression models explored the mediation effects of HBM constructs between health knowledge and mammography use. The final analytical sample included 621 women; 67 did not receive mammography and 554 received mammography. When the regression model was adjusted only for demographic factors, women with adequate health knowledge were more likely to undergo mammography (AOR = 2.321, 95%CI = 1.141-3.809); in regression models including health knowledge and HBM constructs, the likelihood effect of health knowledge declined and became insignificant (AOR = 1.711, 95%CI = 0.985-2.972), indicating potential mediation effects between health knowledge and up-to-date mammography use. Overall, based on the HBM and the KAB theoretical framework, our data support that health belief played a substantial mediating role in the association between health knowledge and mammography uptake, in particular perceived barriers and cues to action in the HBM, which were modifying factors of health beliefs. Therefore, to improve mammography uptake, it may be helpful to design educational model-based interventions through tackling those modifiable perceived barriers and enhancing the intensity of external cues to action.

Abstract
INTRODUCTION South Asian women in Hong Kong have low cervical cancer screening uptake because of multiple barriers to utilizing health resources. Interventions that effectively modify the cancer screening behaviors of this population are warranted. This study evaluates the effects of a community health worker-led multicomponent intervention on improving cervical cancer screening uptake among South Asian women in Hong Kong. STUDY DESIGN This study was an assessor-blind, cluster RCT that included a waitlist control group. SETTING/PARTICIPANTS Recruitment of eligible subjects took place in 6 nongovernmental organizations; these organizations were randomized into intervention and control groups with a 1:1 allocation ratio. INTERVENTION Participants in the intervention group received a 3-month multicomponent intervention comprising health education, monthly telephone follow-ups, and navigation assistance. MAIN OUTCOME MEASURES Participants' cervical cancer screening utilization and beliefs were assessed at baseline, after intervention, and 3 months after intervention. A longitudinal outcome comparison between the 2 groups was performed with generalized estimating equation analysis. Data were collected between September 2018 and January 2020 and were analyzed in 2019-2020. RESULTS A total of 387 participants completed the intervention. A significantly higher cervical cancer screening uptake was observed among participants in the intervention group (97.9%, 191 of 195) than among participants in the control group (52.6%, 101 of 192) at 3 months after intervention (p=0.005). Significantly greater decrements in perceived barriers to cervical cancer screening were found in the intervention group after intervention (-0.68, 95% CI= -1.35, -0.01, p=0.047) and 3 months after intervention (-0.86, 95% CI= -1.69, -0.04, p=0.041). CONCLUSIONS A community health worker-led multicomponent intervention is effective in promoting cervical cancer screening uptake and in reducing barriers to cancer screening utilization among South Asian women in Hong Kong. Combining a community health worker-led intervention with multiple intervention components could be an effective strategy for developing interventions to increase cervical cancer screening in underserved populations. TRIAL REGISTRATION This study was registered at the Chinese Clinical Trial Registry (http://www.chictr.org.cn) ChiCTR1800017227 on July 18, 2018.

Abstract
Background and study aims Gastrointestinal cancer is an important cause of death worldwide. Remote populations are especially vulnerable to these conditions due to reduced access to screening and adequate treatment. In this context, the Belterra project was designed as a pilot taskforce to deliver gastrointestinal screening to an underserved Amazonian population and to spread knowledge and practice to local health workers. This study aimed to describe the implementation and present the results of the Belterra Project. Patients and methods The project took place between October 2014 and December 2017 in Belterra, Pará, Brazil. Public-private partnerships were obtained and were essential for funding. The project required complex logistic solutions to provide gastrointestinal screening to every inhabitant between 50 and 70 years of age, including medical equipment and personal transportation to a remote area. Subjects were asked about their medical history, and received a physical examination, endoscopic examinations, and stool tests. Results Over the course of 19 expeditions, we screened 2,022 inhabitants of Belterra, aged 50 to 70 years. Five colorectal and six gastric adenocarcinomas were diagnosed, as were several lower-stage lesions. Overall, 26 % of the participants undergoing colonoscopy showed some type of colonic lesion. Conclusions Notwithstanding the geographical, cultural, and financial barriers, this study suggests that the implementation of a gastrointestinal cancer screening program for remote Brazilian populations is feasible, reaching high adherence. Although logistics is very demanding, such campaigns may be a good strategy to provide mass gastrointestinal cancer screening for underserved populations.

Abstract
BACKGROUND Screening provides earlier colorectal cancer (CRC) detection and improves outcomes. It remains poorly understood if these benefits are realized with screening guidelines in remote northern populations of Canada where CRC rates are nearly twice the national average and access to colonoscopy is limited.
AIM To evaluate the participation and impact of CRC screening guidelines in a remote northern population.
METHODS This retrospective cohort study included residents of the Northwest Territories, a northern region of Canada, age 50-74 who underwent CRC screening by a fecal immunohistochemical test (FIT) between January 1, 2014 to March 30, 2019. To assess impact, individuals with a screen-detected CRC were compared to clinically-detected CRC cases for stage and location of CRC between 2014-2016. To assess participation, we conducted subgroup analyses of FIT positive individuals exploring the relationships between signs and symptoms of CRC at the time of screening, wait-times for colonoscopy, and screening outcomes. Two sample Welch t-test was used for normally distributed continuous variables, Mann-Whitney-Wilcoxon Tests for data without normal distribution, and Chi-square goodness of fit test for categorical variables. A P value of < 0.05 was considered to be statistically significant.
RESULTS 6817 fecal tests were completed, meaning an annual average screening rate of 25.04%, 843 (12.37%) were positive, 629 individuals underwent a follow-up colonoscopy, of which, 24.48% had advanced neoplasia (AN), 5.41% had CRC. There were no significant differences in stage, pathology, or location between screen-detected cancers and clinically-detected cancers. In assessing participation and screening outcomes, we observed 49.51% of individuals referred for colonoscopy after FIT were ineligible for CRC screening, most often due to signs and symptoms of CRC. Individuals were more likely to have AN if they had signs and symptoms of cancer at the time of screening, waited over 180 d for colonoscopy, or were indigenous [respectively, estimated RR 1.18 95%CI of RR (0.89-1.59)]; RR 1.523 (CI: 1.035, 2.240); RR 1.722 (CI: 1.165, 2.547)].
CONCLUSION Screening did not facilitate early cancer detection but facilitated higher than anticipated AN detection. Signs and symptoms of CRC at screening, and long colonoscopy wait-times appear contributory.

Abstract
The health beliefs and practices regarding cervical cancer screening among women in the mountainous and Terai region of Nepal were investigated and examined for the differences. A descriptive cross-sectional study was conducted with a purposive sample of 216 in mountainous and 294 in Terai. The interview tools were a socio-demographic scale, a Nepalese Health Belief Model Scale for Cervical Cancer followed by the Screening Test. Chi-square test, binary logistic regression, Mann-Whitney U, and Kruskal-Wallis were used to analyze the data. The results showed that the screening rate was low for both regions with a significant difference in the benefit of screening and health motivation. Being older and having a positive family history of cervical cancer were shown to be predictors screening practice. Women from both groups preferred female doctors for screening. Culturally appropriate educational interventions focused on the benefits and obstacles of screening is needed to improve the beliefs of cervical cancer and screening and increase the screening rate. Nurses need to be aware of health beliefs regarding cervical cancer during cervical screening and education.

Abstract
BACKGROUND Cervical cancer incidence and mortality have declined in Australia since the implementation of a national cervical screening program in 1991, however, disparities in both measures between Indigenous and non-Indigenous women remain. We describe spatial and temporal changes in Pap test participation rates by Indigenous status for Queensland (Australia). Analyses were done in the context of renewed screening program in December 2017. METHODS Population-based study 2,132,925 Queensland female residents, aged 20-69 years who underwent cervical screening from 2008 to December 2017; 47,136 were identified as Indigenous through linkage to hospital records. Bayesian spatial models were used to generate smoothed estimates of participation across 528 small areas during 2008-2012 and 2013-2017 compared to the overall state average (2008-2017). Results are presented as thematic maps and graphs showing the associated uncertainty of the estimates. RESULTS Overall screening participation decreased over time for both Indigenous and non-Indigenous women. Strong spatial patterns were evident in five-year participation for both groups. Indigenous women had significantly lower participation than the Queensland average for ≥ 88 % of areas during both reporting periods whereas corresponding estimates were lower than average for <30 % of areas among non-Indigenous women. Disparities by Indigenous status persisted over time and remained across broader geographical groups of accessibility and area disadvantage. CONCLUSIONS Cervical cancer burden in Australia can only be reduced through concentrated efforts on identifying and addressing key drivers of the continuing disparities in screening participation. Achieving equitable screening participation for all women especially Indigenous women requires community engagement and localised interventions.

Abstract
Aboriginal and Torres Strait Islander (collectively, Indigenous Australian) women experience a higher burden of cervical cancer than other women. The National Cervical Screening Program (NCSP) is failing to meet the needs of Indigenous Australian women, resulting in many women not regularly participating in cervical screening. However, one third of Indigenous Australian women do participate in cervical screening. The reasons that some women in this population commence and continue to screen remain unheard but could provide insights to support women who currently do not participate. We aimed to describe Indigenous Australian women’s experiences and views of participation in cervical screening by yarning (a culturally-appropriate interview technique) with 50 Indigenous Australian women aged 25–70 years who had completed cervical screening in the past five years, recruited via Primary Health Care Centres (PHCCs) from three jurisdictions. Aboriginal or Torres Strait Islander women researchers conducted the interviews. Thematic analysis identified six themes: screening as a means of staying strong and in control; overcoming fears, shame, and negative experiences of screening; needing to talk openly about screening; the value of trusting relationships with screening providers; logistical barriers; and overcoming privacy concerns for women employed at PHCCs. Despite describing screening as shameful, invasive, and uncomfortable, women perceived it as a way of staying healthy and exerting control over their health. This ultimately supported their participation and a sense of empowerment. Women valued open discussion about screening and strong relationships with health providers. We identified logistical barriers and specific barriers faced by women employed at PHCCs. This study is strengthened by a research approach that centred Indigenous Australian women’s voices. Understanding the experiences of Indigenous Australian women who participate in screening will help screening providers support women to start and continue to screen regularly. Recommendations for practice are provided.

Prev Med 2020; 134:106018. [PMID: 32057956 DOI: 10.1016/j.ypmed.2020.106018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/08/2019] [Revised: 02/02/2020] [Accepted: 02/07/2020] [Indexed: 02/07/2023]
Abstract
OBJECTIVE Colorectal cancer (CRC) screening using a Faecal Occult Blood Test (FOBT) is a well-established population intervention to reduce mortality and morbidity of CRC. As Indigenous people are not fully benefiting from the screening programs, a greater understanding of barriers and enablers affecting participation is needed. METHODS Searches were carried out in PubMed, Embase, Sociological Abstracts, Scopus, CINAHL, and selected websites. Both qualitative and quantitative studies related to Indigenous populations of Canada, New Zealand, Australia and the United States of America were assessed for quality and data related to FOBT were extracted and synthetised. RESULTS A total of 375 publications were identified and screened against the inclusion/exclusion criteria. Thirty-four studies were included in the review. The barriers for participation in CRC screening included the lack of culturally competent health service access, particularly access to Indigenous health service providers. Medical discrimination, long-standing distrust in Western medicine and/or health staff and screening tests were all identified as barriers for Indigenous people. There were a small number of promising interventions to improve participation, which could be considered on a broader scale to increase overall participation by Indigenous people in CRC screening. CONCLUSIONS The review identified barriers and possible enablers for Indigenous participation in the CRC screening program, some which appear to be unique to Indigenous people. Further intervention studies conducted in partnership with Indigenous communities are needed to improve participation.

Anticancer Agents Med Chem 2020; 20:94-102. [PMID: 31746308 DOI: 10.2174/1871520619666191028100405] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2018] [Revised: 05/24/2019] [Accepted: 07/31/2019] [Indexed: 12/26/2022]
Abstract
Background and Purpose:
Although limited by side effects and development of resistance, doxorubicin still represent the most common chemotherapy for breast cancer. Thus, the identification of critical molecules to alleviate doxorubicin resistance is crucial. Here, we provide a molecular rationale for the breast cancer patients potentially benefitting from doxorubicin based on the expression levels of SIRT1, a identified member of longevity genes.
Methods:
SIRT1-overexpressed and SIRT1-knockdown breast cancer cells were established to investigate the functions of SIRT1 in regulating doxorubicin resistance both in vitro and in vivo. Cell proliferation was analyzed via CCK8 assay, cell apoptosis was studied by TUNEL anslysis. Molecule interaction was analyzed through co-immunoprecipitation and immunofluorescence techniques. Sensibility to doxorubicin was assessed in vivo through nude mice tumorigenicity experiment.
Results::
First, SIRT1 was found higher-expressed in breast cancer doxorubicin-resistant cells MCF-7/ADR than that in doxorubicin- sensitive cells MCF-7. Moreover, SIRT1-knockdown MCF-7/ADR cells showed higher susceptible to doxorubicin both in vitro and in vivo models, whereas overexpressing of SIRT1 obviously inhibited this phenotype. Accordingly, SIRT1 was found interacted with Akt, consequently promoted the activity of Akt in MCF-7/ADR cells in vitro and positively correlated with the expression of P-Akt in vivo. Reversion the activity of Akt partially downturned the doxorubicin-resistant effects mediated by SIRT1.
Conclusion:
This investigation suggested the value of SIRT1 as biomarker of response to doxorubicin, leading to the development of new tools for the management of breast cancer patients.

Abstract
BACKGROUND AND PURPOSE Breast cancer is one of the leading causes of cancer deaths in female worldwide. Doxorubicin represents the most common chemotherapy for breast cancer, whereas side effects and development of resistance impede its effect on chemotherapy. Nicotinamide (NAM), serves as the sirtuins' inhibitor, effectively suppressing various types of cancer. However, the effects of NAM on drug resistance of breast cancer are need to be fully investigated. METHODS Breast cancer doxorubicin-resistant cells MCF-7/ADR and doxorubicin-sensitive cells MCF-7 were applied in this study. Cell proliferation was assessed by CCK8 and colony-forming assays. Cell migration was evaluated by scratch test and transwell assay while cell apoptosis was measured by TUNEL analysis. Expression levels of SIRT1, phosphate Akt (P-Akt, Ser-473) and Akt were measured using western blot analysis. The interrelation between SIRT1 and Akt was investigated by co-immunoprecipitation assay. RESULTS Treatment of nicotinamide combined with doxorubicin effectively inhibited cell growth, suppressed cell migration, and promoted cell apoptosis of MCF7/ADR cells. Mechanistically, nicotinamide translocated SIRT1 from the cell nucleus to cytoplasm, dissociated the connection between SIRT1 and Akt, and consequently decreased expressions of SIRT1, and P-Akt, thereby inhibiting the growth of MCF7/ADR cells. CONCLUSIONS Our results suggested that the value of nicotinamide is a potential therapeutic agent for breast cancer treatment through downregulating SIRT1/Akt pathway, leading to the valid management of breast cancer patients.

Abstract
OBJECTIVE To compare breast screening attendances of Indigenous and non-Indigenous women. METHODS A total of 4,093 BreastScreen cases were used including 857 self-identified Indigenous women. Chi-squared analysis compared data between Indigenous and non-Indigenous women. Logistic regression was used for groupings based on visits-to-screening frequency. Odds ratios and 95% confidence intervals were calculated for associations with low attendance. RESULTS Indigenous women were younger and had fewer visits to screening compared with non-Indigenous women. Non-English speaking was mainly associated with fewer visits for Indigenous women only (OR 1.9, 95%CI 1.3-2.9). Living remotely was associated with fewer visits for non-Indigenous women only (OR 1.3, 95%CI 1.1-1.5). Shared predictors were younger age (OR 12.3, 95%CI 8.1-18.8; and OR 11.5, 95%CI 9.6-13.7, respectively) and having no family history of breast cancer (OR 2.1, 95%CI 1.3-3.3; and OR 1.8, 95%CI 1.5-2.1, respectively). CONCLUSIONS Factors associated with fewer visits to screening were similar for both groups of women, except for language which was significant only for Indigenous women, and remoteness which was significant only for non-Indigenous women. Implications for public health: Health communication in Indigenous languages may be key in encouraging participation and retaining Indigenous women in BreastScreen; improving access for remote-living non-Indigenous women should also be addressed.

Abstract
PURPOSE This systematic review evaluates factors influencing breast cancer outcomes for women treated in Australia, facilitating the exploration of disparities in breast cancer outcomes for certain groups of women in Australia. METHOD A systematic literature search was performed using MEDLINE and Scopus focusing on breast cancer in Australia with outcome measures being breast cancer survival and recurrence with no restrictions on date. Risk of bias was assessed using Cairns Assessment Scale for Observational studies of Risk factors (CASOR). RESULTS Fifteen quantitative studies were included: two were high quality, 11 were intermediate quality, and two were low quality. Traditional risk factors such as invasive tumour type, larger size, higher grade and stage, lymph node involvement and absence of hormone receptors were found to be associated with breast cancer mortality. Being younger (<40 years old) and older (>70 years old), having more comorbidities, being of lower socioeconomic status, identifying as Aboriginal or Torres Strait Islander, living in more rural areas or having a mastectomy were factors found to be associated with poorer breast cancer outcomes. CONCLUSION Despite the heterogeneity of the studies, this review identified significant risk factors for breast cancer mortality and recurrence. The use of this data would be most useful in developing evidence-based interventions and in optimising patient care through creation of a prediction model. PROSPERO REGISTRATION CRD42017072857.

Abstract
Background Breast cancer (BC) has been the commonest malignant tumor with a low survival rate among woman. Long non-coding RNA hypoxia-inducible factor-1 alpha antisense RNA-2 (HIF1A-AS2) was correlated with various cancers. Purpose The study aimed to investigate the roles and related underlying molecular mechanisms of HIF1A-AS2 in BC. Material and methods Target relationships were speculated by Targetscan 7.0 and confirmed by dual luciferase reporter assay. Proteins levels were monitored by RT-qPCR, Western blot and immunohistochemistry assays. CCK-8 assay, SA-β-gal staining and transwell assay were used to detect proliferation, senescence and invasion, respectively. Xenograft nude mice were put into use to evaluate the tumor growth and motility. Results The present study exhibited that HIF1A-AS2 and hypoxia-inducible factor-1 alpha (HIF-1α) were upregulated while miR-548c-3p was downregulated in MDA-MB-231, MCF-7, ZR-75-1, and BT-549 BC cell lines. Bioinformatics analysis showed HIF1A-AS2 and HIF-1α were two targets of miR-548c-3p, and the target relationship was further confirmed by dual luciferase reporter assay. Moreover, knockdown of HIF1A-AS2 by shRNA (sh-HIF1A-AS2) markedly elevated miR-548c-3p level, and the enhanced miR-548c-3p noticeably suppressed cell proliferation, invasion, and epithelial–mesenchymal transition, and promoted senescence in vitro. In addition, overexpression of HIF-1α promoted MCF-7 cell invasion. Intriguingly, low expression of HIF1A-AS2 reduced HIF-1α level by upregulating the expression of miR-548c-3p. Furthermore, experiment in xenograft nude mice has indicated that sh-HIF1A-AS2 inhibited tumor growth and motility by targeting miR-548c-3p through regulating HIF-1α/vascular endothelial growth factor (VEGF) pathway in vivo. Conclusion The inhibitive effect of HIF-1α/VEGF pathway by sh-HIF1A-AS2 through targeting miR-548c-3p plays crucial regulatory roles in BC. Therefore, designing targeted drugs against HIF1A-AS2 provides a new direction for the treatment of BC.

Abstract
Objective China have implemented population-based esophageal cancer (EC) screening programs, however, the participant rates were relatively low. This study was conducted to examine the association between cancer prevention knowledge and EC screening participation rates (PRs). Methods Data in the analyses were obtained from a population-based cancer screening program in four provinces in China since 2007. In the course of 2007−2016, participants who were evaluated as high risk for EC and subsequently recommended for endoscopy examination were included in the final analysis. One-way analysis of variance test, Chi-square test and logistic regression analysis were applied. Results A total of 28,543 individuals assessed as high-risk population for EC were included in this study, with 13,036 males (45.67%) and 15,507 females (54.33%). The prevalence rates of current smoking and alcohol drinking were higher in males (58.25% and 44.22%, respectively) than in females (5.35% and 4.05%, respectively). Participants of females, and those who had older age, lower income, as well as higher education level and cancer prevention knowledge level were more likely to undergo endoscopy. Multivariable analysis showed that higher cancer prevention knowledge was associated with higher PR for endoscopic screening [adjusted odd ratio (aORQ4/Q1) =1.511, 95% confidence interval (95% CI): 1.398−1.632] among our study subjects. This association between cancer prevention knowledge and compliance with endoscopic screening also tends to be strong within subgroups of males, females, aged below 60 years, aged 60 years and above, and lower level of education (illiterate individuals and those with junior high education or less).
Conclusions Our results displayed a positive relationship between cancer prevention knowledge and PRs for endoscopic screening, implying cancer prevention awareness being an independent influence factor for compliance with EC screening. Promoting public campaigns about comprehensive knowledge of cancer prevention seemed to be a reasonable and effective strategy to improve population PRs for EC screening.

Abstract
OBJECTIVES To undertake an descriptive analysis of the health needs, healthcare practices and barriers to accessing healthcare faced by women in Lower Napo River Region, Peru, and to understand health literacy regarding cervical cancer and the need for more effective cervical cancer screening services. METHODS We performed a community-based needs assessment adapting Demographic and Health survey methodology with additional questions determining female health literacy on cervical cancer and assessing the availability and need for cervical cancer screening services. We surveyed women (N = 121) across all households in six communities along the Lower Napo River, Loreto, Peru, in May 2015. Data were collected as part of the larger Amazon Community Based Participation Cervical Cancer Screen-and-Treat Programme. Survey data were compared to national results from ENDES 2014. RESULTS Comparison between our findings and the ENDES 2014 survey highlighted considerable inequality between indigenous or mixed indigenous, rural populations in Loreto, Peru, and national population data averages over level of formal education, literacy, barriers to accessing healthcare and maternal and sexual health. Even though only 5.9% (N = 7/117) of women had no formal health insurance coverage, money was reported as the leading barrier accessing healthcare (N = 88/117, 75.2%). Health literacy regarding cervical and breast cancer was poor. A high proportion of women highlighted fear of screening processes (70.8%, N = 80/113) and lack of available services (53.6%, N = 60/112) as barriers to cervical cancer screening. CONCLUSION Although progress has been made in improving healthcare access in Peru, such gains have not been experienced equitably and women living in remote communities face persistent marginalization regarding their health. There is a significant need for education related to and screening for cervical cancer in this region that is tailored to the reality of women's lives in remote communities in Loreto.

Abstract
BACKGROUND Studies have shown that lncRNA nuclear paraspeckle assembly transcript 1 (NEAT1) is related to breast cancer progression, however, the role of NEAT1 remains largely unknown. The aim of the current study was to further investigate the function of NEAT1 involved in breast cancer. METHODS QRT-PCR was used to analyze lncRNA NEAT1 expression in breast cancer tissues and determine the association between NEAT1 and clinicopathologic features in patients. Kaplan-Meier analysis and the log-rank test were used to establish the relationship between NEAT1 and overall survival. Cell proliferation and invasion were evaluated based on CCK8 cell proliferation, cell colony formation and Transwell cell invasion assays results. Bioinformatics analysis and the luciferase reporter assay were performed to demonstrate the association between NEAT1 and miR-218. RESULTS NEAT1 expression was significantly up-regulated in breast cancer tissues compared to adjacent normal tissues, and higher NEAT1 was positively associated with lymph node metastasis and TNM stage. Patients with higher NEAT1 had a poor prognosis. Furthermore, miR-218 was shown to be a direct target of NEAT1 in breast cancer cells. In addition, NEAT1 promoted cell invasion and proliferation by negatively regulating miR-218 in breast cancer. CONCLUSION NEAT1 is a potential biomarker for prognosis and the target of treatment in breast cancer patients.

Abstract
The silent information regulation factor 1 (sirtuin Type 1, SIRT1), as a kind of NAD+ dependent class III histone deacetylation enzyme, has been found to be involved in tumor proliferation, invasion, and metastasis. The roles of SIRTl in breast cancer is multifaceted depending on its substrate from upstream or downstream signaling pathway. In this study, we sought to make clear the regulating effects of SIRT1 in breast cancer cells, and to explore the underlying mechanisms through which SIRT1 regulates breast cancer. First, our results showed that SIRT1 was significantly up-regulated in breast cancer tissues and cells, which correlated with histological grade, tumor size, as well as lymph node metastasis. Then we established SIRT1-overexpressed and SIRT1- knockdown breast cancer cell lines to investigate the functions of SIRT1 in regulating colony formation, cell proliferation, cell cycle, cell apoptosis and migration. We found that overexpression of SIRT1 significantly promoted breast cancer growth both in vitro and in vivo, whereas knockdown of SIRT1 inhibited these phenotypes. Furthermore, SIRT1 was found to interact with Akt directly, consequently promoting the activity of Akt in breast cancer cells in vitro and positively correlating with expression of Akt, P-Akt, in breast cancer tissues in vivo. Down regulation the activity of Akt partially weakened the proliferative effect mediated by SIRT1. Taken together, our results demonstrated SIRT1's tumor promotion function and potential mechanisms in breast cancer, thus providing valuable therapeutic targets for breast cancer.

Abstract
BACKGROUND Cervical cancer is the second most common female cancer which Ethiopia put a strategic goal to reduce its incidence and mortality by 2020. Lack of knowledge and poor attitude towards the disease and risk factors can affect screening practice and development of preventive behavior for cervical cancer. The aim of this study was to assess knowledge, attitude, practices and factors for each domain for cervical cancer among women of child bearing age in Hossana town, Southern, Ethiopia. METHODS Community based cross sectional study was carried out in June 2015. A total of 583 participants were selected using systematic random sampling technique. Pretested structured interviewer administered questionnaire was used to gather the data. Data were entered in to Epi Info software version 3.5.4 and exported to SPSS version 16 for descriptive and logistic regression analysis. RESULTS Two hundred seventy (46.3%) of the respondents had poor comprehensive knowledge. Only 58 (9.9%) of participants had been screed for the cervical cancer before the survey. Two hundred three (34.8%) of participants had negative attitude towards selected proxy variables. Not having health seeking behavior for cervical cancer [AOR: 5.45, 95% CI: (1.18, 30.58), P <0.031], had not ever received information about cervical cancer and its prevention [AOR: 2.63, 95%CI: (1.78,8.84), P < 0.018] and not actively seeking health information about cervical cancer [AOR: 6.25, (95%CI: (1.26, 31.06) P < 0.025] were significantly associated factors with poor knowledge. Poor knowledge score was associated with poor attitude [AOR: 56.51, 95%CI: (23.76, 134.37), P <0.001]. Had not ever received information about the disease from any source [AOR: 45.24, (95%CI: (11.47, 178.54), P <0.001] was significantly associated factor with not to be screened for the disease. CONCLUSION This study highlighted the importance of awareness creation, increasing knowledge, promoting active searching for health information and experiences of receiving information from any information sources regarding cervical cancer. Therefore, it will be essential to integrate cervical cancer prevention strategies with other reproductive health services at all level of health care delivery system.

Abstract
The Indigenous people of Australia face significant health gaps compared with the general population, with lower life
expectancies, higher rates of death, and chronic illness occurring more often than in non-indigenous Australians. Cancer
is the second largest contributor to the burden of disease with breast cancer being the most common invasive cancer
diagnosed for females. Despite a lower breast cancer incidence compared with non-indigenous women, fatalities occur
at an elevated rate and breast cancers have an earlier age of onset. For indigenous women there are also more advanced
and distant tumours at diagnosis, fewer hospitalisations for breast cancer, and lower participation in breast screening.
Concomitantly there are demographic, socio-economic and lifestyle factors associated with breast cancer risks that
are heavily represented within Indigenous communities. The aim of this two-part narrative review is to examine the
available evidence on breast cancer and its risk factors in Australian Indigenous women. Part One presents a summary
of the latest incidence, survival and mortality data. Part Two presents the risk factors most strongly associated with
breast cancer including age, place of residence, family risk, genetics, reproductive history, tobacco use, alcohol intake,
physical activity, participation in screening and breast density. With increasing emphasis on personalized health care, a
clear understanding of breast cancer incidence, survival, mortality, and causal agents within the Indigenous population
is required if breast cancer prevention and management is to be optimized for Indigenous Australians.

Abstract
BACKGROUND Effective knowledge translation (KT) is critical to implementing program and policy changes that require shared understandings of knowledge systems, assumptions, and practices. Within mainstream research institutions and funding agencies, systemic and insidious inequities, privileges, and power relationships inhibit Indigenous peoples' control, input, and benefits over research. This systematic review will examine literature on KT initiatives in Indigenous health research to help identify wise and promising Indigenous KT practices and language in Canada and abroad. METHODS Indexed databases including Aboriginal Health Abstract Database, Bibliography of Native North Americans, CINAHL, Circumpolar Health Bibliographic Database, Dissertation Abstracts, First Nations Periodical Index, Medline, National Indigenous Studies Portal, ProQuest Conference Papers Index, PsycInfo, Social Services Abstracts, Social Work Abstracts, and Web of Science will be searched. A comprehensive list of non-indexed and grey literature sources will also be searched. For inclusion, documents must be published in English; linked to Indigenous health and wellbeing; focused on Indigenous people; document KT goals, activities, and rationale; and include an evaluation of their KT strategy. Identified quantitative, qualitative, and mixed methods' studies that meet the inclusion criteria will then be appraised using a quality appraisal tool for research with Indigenous people. Studies that score 6 or higher on the quality appraisal tool will be included for analysis. DISCUSSION This unique systematic review involves robust Indigenous community engagement strategies throughout the life of the project, starting with the development of the review protocol. The review is being guided by senior Indigenous researchers who will purposefully include literature sources characterized by Indigenous authorship, community engagement, and representation; screen and appraise sources that meet Indigenous health research principles; and discuss the project with the Indigenous Elders to further explore the hazards, wisdom, and processes of sharing knowledge in research contexts. The overall aim of this review is to provide the evidence and basis for recommendations on wise practices for KT terminology and research that improves Indigenous health and wellbeing and/or access to services, programs, or policies that will lead to improved health and wellbeing.

Abstract
Background: Breast cancer is the commonest cancer among women worldwide. About one in nineteen women in Malaysia are at risk, compared to one in eight in Europe and the United States. The objectives of this study were: (1) to assess patients’ knowledge on risk factors, symptoms and methods of screening of breast cancer; and (2) to determine their perceptions towards the disease treatment outcomes. Methods: A cross-sectional survey using a validated self-administered questionnaire was conducted among 119 consecutive surgical female patients admitted from 1st of September to 8th of October 2015 in Hospital Sultan Abdul Halim, Kedah. Data were analyzed using General linear regression and Spearman’s correlation with Statistical Package for Social Science (SPSS) version 20. Results: Mean (SD) age was 40.6 (15.1) years and majority of the patients were Malay (106, 89.1%). Mean scores for general knowledge, risk factors and symptoms of breast cancer were 50.2 (24.0%), 43.0 (22.9%) and 64.4 (28.4%) respectively. Mean total knowledge score was 52.1(19.7%). 80 (67.2%) and 55 (46.2%) patients were aware of breast self-examination and clinical breast examination recommendations, respectively. Generally, patients had positive perceptions towards breast cancer treatment outcomes. However, majority (59.7%) considered that it would be a long and painful process. Knowledge was significantly better among married women with spouses (p=0.046), those with personal history of breast cancer (p=0.022) and with monthly personal income (p=0.001) with the coefficient of determination, R2=0.16. Spearman’s correlation test showed a significant positive relationship between monthly personal income and breast cancer awareness (r = 0.343, p <0.001). Conclusion: Awareness on breast cancer among our patients was average. Thus, there is a need for more awareness programs to educate women about breast cancer and promote its early detection.

Abstract
The purpose of the present study was to investigate the effects of upregulating microRNA (miR)-181b expression in tumor-associated macrophages regarding breast cancer cell metastasis and to identify the target gene. Ectopic miR-181b was transfected into MDA-MB-231 and MCF-7 breast cancer cell lines with or without chemokine ligand 18 (CCL18) stimulation. Cell proliferation, migration/invasion and apoptosis rate were investigated. The binding effects of miR-181b to the 3'-untranslated region (UTR) of the nuclear factor (NF)-κB gene were detected with the dual luciferase reporter system. Immunofluorescent staining of the NF-κB key component P65 was performed. The messenger (m) RNA and protein expression of NF-κB induced by CCL18 with or without miR-181b stimulation was evaluated with reverse transcription-quantitative polymerase chain reaction and western blot analysis. When compared with the CCL18-stimulated group, miR-181b mimic-transfected cells exhibited significantly inhibited proliferation and migration, with an increased cell apoptosis percentage in a dose-dependent manner. Furthermore, the luciferase activity was reduced for cells with NF-κB 3'-UTR wild-type that were co-transfected with miR-181b mimics. Immunofluorescent staining of NF-κB demonstrably weakened the P65 signal in stimulated miR-181b mimic cells when compared with parental and CCL18-treated cells. The increased expression level of NF-κB induced by CCL18 in MDA-MB-231 and MCF-7 cells was suppressed by miR-181b mimics. Overexpression of miR-181b suppressed cell survival rate and migration. This overexpression may achieve this goal by regulating the NF-κB pathway in breast cancer cells. Our study demonstrated a potential therapeutic application of miR-181b in the treatment of breast cancer.

Abstract
Objective: To assess aspects related to cancer in indigenous population. Methods: This is a retrospective study developed in a public university hospital. We included patients with 18 or more years of age, diagnosed with solid tumors, and followed between 2005 and 2015. Clinical features were assessed by descriptive statistics, and survival was evaluated by Kaplan-Meier curves and multivariate Cox regression. Results: Fifty patients were included. The cancer incidence was 15.73 per 100,000. The mean age at diagnosis was 54 years and most patients were female (58%). Cancer of the cervix (28%) and prostate (16%) were the most common. The mean time between the onset of symptoms and the diagnosis was 9 months and from diagnosis to the treatment was 3.4 months. Disease diagnosed at stage IV (17%) had worse overall survival (HR: 11.4; p<0.05). The 5-year survival rate ranged from 88% for prostate cancer to 0% for lung cancer. All 5-year survival rates were lower as compared to other populations. Conclusion: The most prevalent cancer sites were cervix and prostate. Disease stage and primary site were prognostic factors. Objetivo: Avaliar os aspectos relacionados a câncer em populações indígenas. Métodos: Estudo retrospectivo conduzido em um hospital universitário público. Foram incluídos pacientes com 18 anos ou mais, diagnosticados com tumores sólidos e acompanhados entre 2005 e 2015. Os aspectos clínicos foram avaliados por meio de estatística descritiva, e a sobrevida foi avaliada por meio de curvas de Kaplan-Meier e regressão multivariada de Cox. Resultados: Foram incluídos 50 pacientes. A incidência de câncer foi 15,73 por 100 mil. A média de idade ao diagnóstico foi 54 anos, e a maioria era do sexo feminino (58%). O câncer de colo uterino (28%) e o de próstata (16%) foram os mais frequentes. O tempo médio entre o início dos sintomas e o diagnóstico foi 9 meses, e entre o diagnóstico e o tratamento, de 3,4 meses. Doença diagnosticada no estágio IV (17%) resultou em pior sobrevida global (HR: 11,4; p<0,05). A sobrevida em 5 anos variou de 88% para o câncer de próstata a 0% para pulmão. Todas as taxas de sobrevida em 5 anos foram menores em comparação a outras populações. Conclusão: Os locais mais frequentes de neoplasia foram colo de útero e próstata. O estágio da doença e o sítio primário foram fatores prognósticos.

Abstract
INTRODUCTION National guidelines call for annual lung cancer screening for high-risk smokers using low-dose computed tomography (LDCT). The objective of our study was to characterize patient knowledge and attitudes about lung cancer screening, smoking cessation, and shared decision making by patient and health care provider. METHODS We conducted semistructured qualitative interviews with patients with histories of heavy smoking who received care at a Federally Qualified Health Center (FQHC Clinic) and at a comprehensive cancer center-affiliated chest clinic (Chest Clinic) in Albuquerque, New Mexico. The interviews, conducted from February through September 2014, focused on perceptions about health screening, knowledge and attitudes about LDCT screening, and preferences regarding decision aids. We used a systematic iterative analytic process to identify preliminary and emergent themes and to create a coding structure. RESULTS We reached thematic saturation after 22 interviews (10 at the FQHC Clinic, 12 at the Chest Clinic). Most patients were unaware of LDCT screening for lung cancer but were receptive to the test. Some smokers said they would consider quitting smoking if their screening result were positive. Concerns regarding screening were cost, radiation exposure, and transportation issues. To support decision making, most patients said they preferred one-on-one discussions with a provider. They also valued decision support tools (print materials, videos), but raised concerns about readability and Internet access. CONCLUSION Implementing lung cancer screening in sociodemographically diverse populations poses significant challenges. The value of tobacco cessation counseling cannot be overemphasized. Effective interventions for shared decision making to undergo lung cancer screening will need the active engagement of health care providers and will require the use of accessible decision aids designed for people with low health literacy.

Abstract
OBJECTIVE To examine a) the implementation and use of a DVD developed to educate Aboriginal people about bowel cancer and bowel cancer screening; and b) broader aspects of Aboriginal participation in the National Bowel Cancer Screening Program. METHODS Qualitative methods and descriptive approaches were used. Data were collected using face-to-face and telephone interviews and focus group discussions. There were 67 participants, including those involved in the development and distribution of the DVD, health professionals and Aboriginal community members. RESULTS Although the DVD received a positive reaction from participants, fewer than half the DVDs had been distributed. Furthermore, the small number of DVDs that had been distributed were under-utilised. CONCLUSION The weaknesses do not appear to lie with the resource itself but can be attributed partly to poor distribution and promotion. This may have been compounded by the structure of the National Bowel Cancer Screening Program, which limited the engagement of Aboriginal community members and health providers whose focus is largely directed towards more pressing health care issues. IMPLICATIONS Interest in the resource may increase once the Aboriginal component of the screening program is more closely linked with primary care.

[PMID: 27257363 PMCID: PMC4886273 DOI: 10.1093/swr/svw006] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/08/2015] [Revised: 08/25/2015] [Accepted: 09/14/2015] [Indexed: 05/22/2023]
Abstract
Research has consistently documented lower colorectal cancer (CRC) screening rates for racial and ethnic minority populations, with the lowest screening rates among American Indians (AIs). Given the low CRC screening rates among AIs residing in the Northern Plains region, the objective of this research was to identify CRC screening correlates for Northern Plains AIs. With a sample of 181 AIs age 50 years or older, the authors used Andersen's behavioral model to examine the following factors related to receipt of CRC screening: (a) predisposing factors-age, education, marital status, and gender; (b) need factors-personal and family history of cancer; and (c) enabling factors-having a particular place to receive medical care, annual health checkup, awareness of the availability of CRC screening, knowledge of CRC, and self-efficacy of CRC. Nested logistic regression identified the following correlates of receipt of CRC screening: (a) predisposing factors-older age; (b) need factors-having a personal history of cancer; and (c) enabling factors-having an annual health checkup, greater awareness of CRC screening, and greater self-efficacy of CRC. Given the findings, prevention and intervention strategies, including public awareness and education about CRC screening, are promising avenues to reduce cancer screening disparities among AIs.

Abstract
BACKGROUND MicroRNAs are believed to influence breast cancer cell tumorgenicity by interacting with the production of tumor associated macrophages. At this stage, this hypothesis lacks sufficient empirical evidence. Our study is an investigation of the effects of let-7a on the function of human breast cancer cell lines that had undergone chemokine ligand 18 (CCL18) stimulation. METHODS Two breast cancer cell lines MDA-MB-231 and MCF-7 were transfected with let-7a mimics with or without CCL18 simulation. The expression level of let-7a was evaluated with qRT-PCR. Our study examined cell proliferation, migration and cell cycles following let-7a treatment. The predicted target of let-7a was identified and confirmed in vitro by a dual luciferase reporter system. The associations between let-7a, CCL18 and target gene expression were evaluated using RT-PCR and the Western blotting method. RESULTS The downregulated expression level of let-7a was observed in both breast cancer cell lines. When compared to the control and CCL18 stimulation groups, cell proliferation and migration in MDA-MB-231 and MCF-7 cells were significantly inhibited by let-7a. Furthermore, the cell cycle was dramatically blocked at the G2/M phase. The luciferase reporter identified Lin28 as the direct binding target of let-7a in both breast cancer cell lines. CONCLUSION Upregulation of let-7a carries the potential to reverse CCL18 induced cell proliferation and migration alteration in breast cancer cells by regulating Lin28 expression. Our results provided evidence which suggests the use of let-7a as a therapeutic agent in the treatment of breast cancer.

Abstract
Regular Papanicolaou (Pap) screening has dramatically reduced cervical cancer incidence in Canada since the 1950s. However, Indigenous women's rates of cervical cancer remain disproportionately high, a factor which is not acknowledged in national media or in educational materials reporting Canada's new cervical cancer screening guidelines. Here, we present findings from a cervical cancer screening initiative in Northwestern Ontario. Based on participatory action research, we worked with 10 First Nations communities in the Robinson Superior Treaty area to increase awareness of cervical cancer risk, develop culturally sensitive tools for screening and education and test the efficacy of human papillomavirus (HPV) self-sampling as an alternative to Pap cytology. We conducted 16 interviews with health care professionals and 9 focus groups with 69 women from the communities. A central theme for both health care providers (HCPs) and community members was the colonial legacy and its influence on women's experiences of cervical cancer screening. This was evidenced by a strong sense of body shyness, including shame related to sexuality and sexually transmitted infections, concerns about confidentiality in clinical encounters and distrust or caution around HCPs. Reaffirming women's traditional caregiving and educational roles, enhancing mother and daughter communication, improving cultural sensitivity in health care and education and adoption of HPV self-sampling to increase women's privacy and control of the cervical cancer screening experience were endorsed. We argue that education and screening initiatives must reflect the cultural preferences of Indigenous women, empowering them to take control of their experiences of health and body in cervical cancer screening.
