“…Focusing on SA specifically, epidemiological analysis carried out for the CanDAD project has identified a range of disparities in outcomes that warrant consideration when tailoring health services to meet the needs of this population. For example, in line with national data, Aboriginal people are generally younger when diagnosed with cancer, with a difference in median age of diagnosis of 10 years (58 vs 68 years) . The scale of the disparity may be more fully appreciated when expressed as years of life affected by cancer .…”

“…Aboriginal people are more likely to be diagnosed with cancers with poorer prognosis . Cancers of the liver, gallbladder, head and neck, oesophagus and lung are relatively more common among Aboriginal people, while melanoma, breast and prostate tumours are relatively less common . These cancers are also commonly detected at later stages, more metastasized or disseminated cancer at diagnosis compared to non‐Aboriginal people of the same age, sex and cancer type .…”

“…Over half the Aboriginal people diagnosed with cancer in SA live in outer regional and remote regions . Consequently, the degree to which they can benefit from cancer treatments is limited by a lack of local services (including for screening and early detection) . Long distance travel is often necessary to access specialist treatment, leading to experiences of isolation from community, as well as language and cultural differences.…”

“…Long distance travel is often necessary to access specialist treatment, leading to experiences of isolation from community, as well as language and cultural differences. 4 These difficulties are reflected in the epidemiological data with those living in remote locations at the time of diagnosis being significantly more likely to die within 5 years of that diagnosis compared to those living in a major city (31.1% vs 48.2%, P < .001) . These disparities are difficult to understand and address without a deeply contextualized qualitative understanding of cancer experiences.…”

BackgroundAboriginal people with cancer experience worse outcomes than other Australians for a range of complex and interrelated reasons. A younger age at diagnosis, higher likelihood of more advanced cancer or cancer type with poorer prognosis, geographic isolation and cultural and language diversity mean that patient pathways are potentially more complex for Aboriginal people with cancer. In addition, variation in the quality and acceptability of care may influence cancer outcomes.ObjectiveThis study sought to understand how care coordination influences Aboriginal people's experiences of cancer treatment.MethodsInterviews with 29 Aboriginal patients or cancer survivors, 11 carers and 22 service providers were carried out. Interviews were semi‐structured and sought to elicit experiences of cancer and the health‐care system. The manifest content of the cancer narratives was entered onto a cancer pathway mapping tool and underlying themes were identified inductively.ResultsThe practice of cancer care coordination was found to address the needs of Aboriginal patients and their families/carers in 4 main areas: “navigating the health system”; “information and communication”; “things to manage at home”; and “cultural safety”.ConclusionsThe CanDAD findings indicate that, when the need for cancer care coordination is met, it facilitated continuity of care in a range of ways that may potentially improve cancer outcomes. However, the need remains unmet for many. Findings support the importance of dedicated care coordination to enable Aboriginal people to receive adequate and appropriate patient‐centred care, so that the unacceptable disparity in cancer outcomes between Aboriginal and non‐Aboriginal people can be addressed.

“…In Australia, the incidence of HPV-related oropharyngeal squamous cell carcinoma (OPSCC) increased among men and women by an estimated 1% per year from 1982 to 2005 [7]. Indigenous Australians are over-represented in almost all head and neck cancers [8]. However, the prevalence of oral HPV infection, and HPV-related OPSCC, among Indigenous Australians is unknown.…”

Background: The prevalence of oral HPV infection and HPV-related oropharyngeal squamous cell carcinoma (OPSCC) among Indigenous Australians is unknown. This paper outlines the engagement, consultation and recruitment strategies for a study involving investigation of HPV and OPSCC among Indigenous South Australians, based on the consolidated criteria for strengthening the reporting of health research involving Indigenous Peoples (CONSIDER) statement. Methods: Initial consultations with all interested Aboriginal Community Controlled Health Organisations (ACCHOs) were done throughout 2014 and 2015. This resulted in a funding application submitted that reflected Indigenous community views and inputs in study design and methodology, and which included nine Indigenous investigators. Once funding was received, community consultation was again undertaken, with six ACCHOs providing structures, strategies and recommendations for how recruitment for participants taking part in the study should be undertaken. Staff were hired (n = 6), with non-Indigenous staff (n = 3) undertaking extensive cultural competency training. An Indigenous Reference Group was established to provide oversight and cultural guidance. Recruitment of Indigenous participants by trained field officers occurred between Feb 2018 and Dec 2018, with n = 1011 recruited. Qualitative records summarising research staff contact with ACCHOs and participants were documented. These records, together with field trip notes, key ACCHO stakeholder reflections and research staff comments, were reviewed to summarise the culturally sensitive strategies that appeared to work most successfully to facilitate ACCHO and participant buy-in.

IMPORTANCE Human papillomavirus (HPV) infection is associated with oropharyngeal squamous cell carcinoma. International estimates suggest overall oral HPV prevalence is 7.5%, with prevalence of oral HPV types 16 and 18 being 1.6%; prior Australian estimates suggest oral HPV prevalence is 2.3%, with HPV-16 and HPV-18 being 1.3%. OBJECTIVES To estimate the prevalence of oral HPV infection among Indigenous Australians and to report the prevalence of factors associated with high-risk HPV types (ie, HPV-16 and HPV-18) and HPV types linked with Heck disease (ie, HPV-13 and HPV-32). DESIGN, SETTING, AND PARTICIPANTS This cross-sectional study analyzed HPV screening results from saliva samples collected from 1011 Indigenous Australians between February 2018 and January 2019. Data were analyzed from May 2018 to May 2019. Recruitment occurred through Aboriginal Community Controlled Health Organisations in South Australia. Eligibility included identifying as Indigenous, residing in South Australia, and being aged 18 years or older. MAIN OUTCOMES AND MEASURES Saliva samples were collected, with microbial DNA for genotyping extracted. Sociodemographic parameters, health-related behaviors, and sexual history data were collected. Analyses were stratified by sex as well as by HPV types 13 and 32 (Heck disease) and 16 and 18 (high risk of oropharyngeal squamous cell carcinoma). Multivariable analyses were conducted to obtain adjusted odds ratios (ORs). RESULTS Data were obtained for 910 participants (median [interquartile range] age, 37 [27-51] years); 595 participants (65%) were female and 572 (63%) resided in nonmetropolitan locations. In all, 321 saliva samples (35.3%; 95% CI, 32.2%-38.4%) were positive for oral HPV (106 [33.7%] men; 215 [36.1%] women). The highest prevalence was found for HPV types 13 and 32 (207 [22.7%] total; 60 [19.0%] men; 147 [24.7%] women) followed by HPV types 16 and 18 (30 [3.3%] total; 9 [2.9%] men; 21 [3.5%] women). After multivariable analysis, risk factors associated with HPV types 13 and 32 included nonmetropolitan residential status (OR, 2.06; 95% CI, 1.10-3.88) and not having had a tonsillectomy (OR, 2.74; 95% CI, 1.05-7.16). Among women, having obtained a high school education or less was associated with lower odds of HPV-16 and HPV-18 infection (OR, 0.16; 95% CI, 0.03-0.97). CONCLUSIONS AND RELEVANCE Prevalence of oral HPV infection in a large sample of Indigenous Australians was high, with one-third testing positive. The most prevalent HPV types were those associated with Heck disease. The prevalence of HPV types associated with oropharyngeal squamous cell carcinoma exceeded both Australian and international population-level estimates.
