Abstract

Introduction

The incidence of early-onset bowel cancer (EOBC) is increasing in Australia and globally. However, the burden of EOBC among First Nations Australians is rarely determined. This study aimed to quantify the diagnosis and survival rates of EOBC among First Nations Peoples in Queensland, Australia.

Methods

CancerCostMod, a linked administrative dataset of patients diagnosed with cancer in Queensland from 1st July 2011 to 30th June 2015, was used. EOBC was defined as a diagnosis of bowel cancer (i.e., colon, rectosigmoid, or rectal cancer) at 18–49 years of age. A multivariable logistic regression analysis was employed to determine the association of Indigenous status and other factors with a diagnosis of EOBC. Five-year survival rates were used to estimate the survival rate.

Results

Of 11,702 bowel cancer cases, 9.2% (95% CI: 8.7%–9.7%) were EOBC, with 19% among First Nations peoples and 9% among Non-First Nations. First Nations Australians had 2.6 times the odds of EOBC diagnosis (95% CI: 1.7–4.0) compared with Non-First Nations Australians. Overall, EOBC patients showed a significantly higher 5-year survival rate of 77% compared with 60% for late-onset bowel cancer patients. However, First Nations EOBC patients showed a lower 5-year survival rate (73%) than Non-First Nations EOBC patients (77%).

Conclusion

First Nations Australians have more than double the diagnosis rates and lower 5-year survival for EOBC compared to Non-First Nations. Whilst the recent lowering of the age eligibility for the National Bowel Cancer Screening Program is a beneficial strategy to address the increasing incidence of EOBC, special consideration should be given to addressing the higher diagnosis rates and lower survival among First Nations Australians. This study raises the potential for further lowering the age eligibility for First Nations Australians to ensure younger First Nations Australians can access screening for earlier detection, thereby improving their survival from bowel cancer.

期刊介绍： Cancer Medicine is a peer-reviewed, open access, interdisciplinary journal providing rapid publication of research from global biomedical researchers across the cancer sciences. The journal will consider submissions from all oncologic specialties, including, but not limited to, the following areas: Clinical Cancer Research Translational research ∙ clinical trials ∙ chemotherapy ∙ radiation therapy ∙ surgical therapy ∙ clinical observations ∙ clinical guidelines ∙ genetic consultation ∙ ethical considerations Cancer Biology: Molecular biology ∙ cellular biology ∙ molecular genetics ∙ genomics ∙ immunology ∙ epigenetics ∙ metabolic studies ∙ proteomics ∙ cytopathology ∙ carcinogenesis ∙ drug discovery and delivery. Cancer Prevention: Behavioral science ∙ psychosocial studies ∙ screening ∙ nutrition ∙ epidemiology and prevention ∙ community outreach. Bioinformatics: Gene expressions profiles ∙ gene regulation networks ∙ genome bioinformatics ∙ pathwayanalysis ∙ prognostic biomarkers. Cancer Medicine publishes original research articles, systematic reviews, meta-analyses, and research methods papers, along with invited editorials and commentaries. Original research papers must report well-conducted research with conclusions supported by the data presented in the paper.
