INTRODUCTION: Despite 3% of Australians identifying as Indigenous, cutaneous malignancies in these patients, including incidence, risk factors and outcomes have not been investigated. This is despite recognition that cancer outcomes in this population are significantly poorer.METHODS: We undertook a retrospective case series of Indigenous Peoples who presented to two urban cancer therapy centres for the management of cutaneous malignancies from 2003 to 2017. Risk factors, tumour-specific characteristics, treatments and outcomes were reviewed.RESULTS: Twenty-two patients identified as Aboriginal and/or Torres Strait Islander. The median age at presentation was 61 years and the majority were male (63.6%) and had skin phototype III (86.4%). Patients presented with basal cell carcinoma (50%), squamous cell carcinoma (31.8%), melanoma (9.1%) and cutaneous sarcomas (9.1%). The majority (68.2%) presented with stage II or higher disease, and there were high rates of immunosuppression (45.5%). At the time of reporting, 68.2% patients were alive, 18.2% had died from their skin cancers and 13.6% had died from unrelated causes.CONCLUSION: This cohort has demonstrated late-stage presentation of skin cancers, with substantial morbidity and mortality from potentially treatable cutaneous malignancies. This parallels other health conditions in Indigenous Australians and has highlighted the need for improved data collection of Indigenous status to better quantify the epidemiology of skin cancer in this population. There is an imperative to improve skin cancer awareness in this population to allow earlier detection and management to ensure better outcomes.
