Unveiling a Health Disparity: Comparative Analysis of Head and Neck Cancer Trends between First Nations People and Non-Indigenous Australians (1998–2015).

Simple Summary: This study focused on the trends of Head and Neck Cancers (HNC) in the First Nations people of Australia. There is an underwhelming amount of literature holistically analysing the trend of HNC among the First Nations people. This study comprehensively analysed incidence, mortality, and survival rates in the First Nations people, and compared these trends with the non-Indigenous Australian population. This emphasized the need to investigate the underlying causes and barriers for differences in the HNC burden between First Nations people and non-Indigenous Australians. Collaborative efforts, spanning from local to national levels, are required to address the HNC burden in Australia, particularly, in First Nations communities. Background: We aim to assess and compare the HNC trends between the First Nations and non-Indigenous population. Methods: HNC incidence (1998–2013) and mortality (1998–2015) data in First Nations people and non-Indigenous Australians were utilised from the Australian Cancer Database. The age-standardised incidence and mortality trends along with annual percentage changes were analysed using Joinpoint models. Age-standardised incidence and mortality rates according to remoteness, states, and five-year survival rates among First Nations people and non-Indigenous Australians were presented as graphs. Results: First Nations people had over twice the age-standardised incidence (2013; 29.8/100,000 vs. 14.7/100,000) and over 3.5 times the age-standardised mortality rates (2015; 14.2/100,000 vs. 4.1/100,000) than their non-Indigenous counterparts. Both populations saw a decline in mortality, but the decline was only statistically significant in non-Indigenous Australians (17.1% decline, 1998: 4.8/100,000, 2015: 4.1/100,000; p < 0.05). Across all remoteness levels and states, First Nations people consistently had higher age-standardised incidence and mortality rates. Furthermore, the five-year survival rate was lower by 25% in First Nations people. Conclusion: First Nations people continue to shoulder a disproportionate HNC burden compared to non-Indigenous Australians. [ABSTRACT FROM AUTHOR]
