Australian researchers are difficult decades-old assumptions about mind most cancers remedy in a bid to make radiation remedy simpler in opposition to tumors, whereas decreasing harm to wholesome tissue.
The groundbreaking work, led by Professor Ivan Kempson from Adelaide College, has obtained $240,000 by means of the Mark Hughes Basis Heart for Mind Most cancers Analysis (MHF Heart) on the College of Newcastle to assist an MHF Centre Innovation Node for Radiobiology.
The undertaking is the primary to be introduced underneath a brand new nationwide funding initiative designed to strengthen collaboration and quick monitor promising mind most cancers analysis.
The analysis focuses on one of the crucial used remedies for mind most cancers: radiation remedy.
Whereas radiation performs an important position in treating mind tumors, scientists nonetheless don’t absolutely perceive precisely the way it impacts tumor cells, wholesome cells, and the physique’s immune system.
In response to Professor Kempson, a biophysicist at Adelaide College’s Future Industries Institute, a lot of what’s presently accepted about radiation biology dates again to analysis from the Nineteen Sixties and Nineteen Seventies.
It’s time to take a contemporary look. There may be nonetheless a lot we do not learn about mind most cancers and the way radiation impacts the physique.
We’re going again to fundamentals, questioning long-held assumptions and utilizing new applied sciences to higher perceive what is admittedly taking place at a mobile stage.”

Some of the thrilling features of the undertaking is the usage of specialised instruments which are the primary of their sort in Australia. These instruments enable researchers to measure radiation harm to DNA with a stage of precision that has not beforehand been attainable.
DNA harm is likely one of the fundamental ways in which radiation kills most cancers cells. By understanding precisely how that harm happens, researchers hope they will discover methods to extend the impression of radiation on tumor cells whereas defending wholesome mind tissue.
“We’re how we are able to improve DNA harm in tumor cells, however defend DNA in regular cells as properly,” Professor Kempson mentioned.
The workforce can also be investigating how radiation influences the immune system. More and more, researchers consider that the physique’s personal immune response may play a big position in serving to battle mind most cancers, however there are nonetheless many unanswered questions on how radiation impacts immune cells inside a tumor.
To reply these questions, Professor Kempson’s workforce is working carefully with clinicians on the Royal Adelaide Hospital, conducting analysis in a real-world remedy surroundings utilizing the identical high-energy tools used to deal with sufferers. This method is offering insights that can not be gained by means of conventional laboratory research alone.
“For households affected by mind most cancers, advances are urgently wanted. The outcomes are very poor and survival charges have modified little previously 35 years, with solely two in 10 sufferers surviving past 5 years. It kills extra youngsters than another illness and extra individuals underneath 40 than another most cancers.”
Regardless of its devastating impression – one Australian is recognized each 5 hours – mind most cancers receives lower than 5% of federal most cancers analysis funding.
MHF Heart Director Professor Mike Fay mentioned the undertaking demonstrates the significance of investing in modern analysis and nationwide collaboration.
“Mind most cancers is an extremely advanced illness and there’s no single answer,” Professor Fay mentioned.
“By bringing collectively consultants with totally different abilities and supporting the very best concepts in Australia, we’re constructing the data that might result in higher remedies and higher outcomes for sufferers.”
The funding may even assist develop Australia’s mind most cancers analysis workforce, supporting scientists devoted to tackling one of many nation’s best unmet medical challenges.
As the primary of three Innovation Companion Node tasks to be introduced in 2026, the funding marks one other step in the direction of a coordinated nationwide effort to enhance outcomes for individuals recognized with mind most cancers.
