CANARY (CANcer risk in patients with unexpected weight loss in primaRY care) Studies: Clinical Decision Support Systems for Cancer Prevention and Early Cancer Detection in Primary Care
Dr. Javiera Martinez Gutierrez,
General practitioners address many conditions in their day-to-day practice. There are more than 100 frequent conditions that need to be addressed by GPs in primary care. Unexpected weight loss is one of those conditions. It has proven to be a risk factor for cancer, and yet, most of the time, its presence will not lead to a cancer diagnosis. Nonetheless, the challenges of considering a cancer diagnosis in the presence of non-specific symptoms and mildly abnormal standard test results can lead to missed opportunities to diagnose cancer early in primary care.
Primary care practices, through their Electronic Medical Record systems (EMRs) hold an immense amount of information regarding patients’ personal and family history, signs, symptoms, and pathology test results through time. This information can be stored in primary care datasets and used to improve care in general practice.
A previous collaboration at the University of Melbourne and Western Health called Future Health Today (FHT), allowed us to develop simple models to identify patients at risk of undiagnosed cancer using abnormal blood test results in primary care. In this new set of studies, we will enrich these models by adding other features, like symptoms and additional abnormal test results to identify patients that may be at risk of undiagnosed cancer. In particular, we are closely working with UK researcher Dr. Brian Nicholson and his team at the University of Oxford, to validate their risk prediction model based on unexpected weight loss as a risk factor for cancer in Australian populations.
This research will develop and implement a new tool that will prompt GPs to promptly investigate patients who may be at risk of undiagnosed cancer, using information available in the medical records. We hope to improve early cancer detection and cancer outcomes in general practices throughout Australia.

FHT is a collaboration between The University of Melbourne and Western Health (https://futurehealthtoday.com.au). This research is supported by the Medical Research Future Fund’s Rapid Applied Research Translation program in conjunction with the Melbourne Academic Centre for Health and the Paul Ramsay Foundation.
Dr. Javiera Martinez Gutierrez is supported by the Victorian Cancer Agency Mid-Career Fellowship and the Australian Government Research Training Program.
This study extends our work on using linked data to develop cancer diagnostic algorithms and implementing them in the Future Health Today diagnostic decision support system. We aim to identify patients with non-specific symptoms such as weight loss and prompt early investigation as an approach to improve cancer outcomes.
