Paving the way to tackle liver cancer
In 2023, Cancer Council NSW-funded research played a pivotal role in the delivery of Australia’s first Roadmap to Liver Cancer Control.
This new Roadmap is very much needed, as the liver cancer death rate has increased 80% in the past 20 years alone.
Daffodil Centre* researchers led on developing best-practice clinical guidelines for the Roadmap, which will help clinicians identify and manage people at increased risk of liver cancer.
“If we can identify individuals affected and take a consistent, evidence-based approach to surveillance, treatment and care, we can in many cases stop liver cancer developing,” says Professor George, who co-led the creation of the Roadmap.
The multidisciplinary expert group for the new Roadmap was co-chaired by Dr Nicole Allard, a GP specialising in hepatitis control, and Professor Jacob George, a hepatologist and longstanding Cancer Council NSW research partner.

Looking ahead, the challenge is now to ensure the Roadmap is implemented into standard practice across the country.
Professor George says that “after 50 years of liver cancer rates steadily increasing, this is our best opportunity to turn things around – and address one of the worst causes of inequity in cancer outcomes in Australia.”

Doctor Jeremy Booth
Using A.I. to enhance radiotherapy effectiveness
Artificial intelligence
Harnessing the power of artificial intelligence, in this project Dr Booth and his team will implement “beam’s-eye-view” tracking technology during radiation treatment for prostate, liver and pancreas cancer patients.
With beam’s-eye-view tracking, the cancer is tracked at all time during radiation therapy treatment, ensuring high accuracy and high precision treatment.
For the patients, this means their cancer is hit and destroyed while their healthy tissue and organs are protected from damage.
Prof. Peter Leedman AO
Finding new ways to treat liver cancer
Targeting the liver
In this project, Professor Leedman and his team will investigate a new treatment approach that combines a new drug delivery method capable of specifically targeting the liver, with a new anticancer drug shown to ‘switch off’ cancer cells.
Once this new treatment has been developed the team will test their approach in pre-clinical models in the lab.
They’ll then conduct further pre-clinical tests to see how effective this new treatment is when combined with existing liver cancer treatments.
Prof. Geoffrey McCaughan
Using combination therapies to treat liver cancer
Artificial intelligence
Hepatocellular Carcinoma (HCC) is the most common type of primary liver cancer and it is the sixth leading cause of cancer–related death in Australia. Once HCC has spread to other parts of the body, there are very few effective treatment options and the overall five-year survival rate is less than 20%.
Professor McCaughan’s team have developed two potential new treatments which target HCC cells, the surrounding blood vessels and the immune system within the tumour. In this project, the team will test these new therapies in combination with each other in pre-clinical models to identify the most effective way to target and kill HCC cells.
By targeting several different components of the tumour the team hope to maximise the effectiveness of the drugs they have developed. Using the expertise of his team, Professor McCaughan aims to translate the results from the laboratory into clinical trials, where they hope their new treatment approach will improve outcomes for patients with HCC, especially those with a poor prognosis.

A new approach to fighting drug resistance
Fighting drug resistance
Cells known as stem cells that exist within a liver cancer are known to play a key role in the progression of liver cancer and the development of resistance to drugs. But attempts to target and kill these stem cells have been disappointing.
This project focuses on using aptamer molecules, also known as chemical antibodies, to target liver cancer stem cells. Prof. George and his team have generated aptamers against two important surface markers that identify liver cancer stem cells. They have also shown these aptamers can be combined with a widely used anticancer drug to form a ‘therapeutic complex’.
