Study backs Rhythm's colorectal risk model
Proprietary geneType assessment enhanced and cross-validated using data from nearly 400,000 individuals in UK Biobank
Next generation geneType design continues focus on usability and simplicity, while providing superior performance
Special Report: Rhythm Biosciences has published a peer-reviewed study in PLoS One validating its next-generation colorectal cancer risk assessment model, marking a major step forward in predictive cancer diagnostics.
Rhythm Biosciences (ASX:RHY) said the study detailed updates and improvements to its proprietary geneType colorectal cancer risk assessment, which was enhanced and cross-validated using data from nearly 400,000 individuals in the UK Biobank.
Rhythm said the article titled 'Colorectal cancer risk prediction using a simple multivariable model' described creation and validation of a new risk model that incorporated sex-specific factors and outperformed current models.
The company said as colorectal cancer was a disease associated with many environmental and lifestyle risk factors, the study focused on expanding its geneType model beyond the two primary risk factors – family history and polygenic risk.

Key findings of study
Rhythm said the study delivered several key findings, most notably development of the enhanced risk model that incorporated three additional risk factors.
These factors were selected for their strong associations with colorectal cancer and ease of use in a clinical setting, improving the model's predictive performance over standard family history assessments.
The company said the most impactful risk factors were identified and integrated into an updated geneType risk model, which was then tested using data from the UK Biobank.
Rhythm said other key findings included:
Commitment to improvement – The study highlighted the importance of including clinical and lifestyle factors in multifactorial diseases like colorectal cancer.
Commercial application – The new model was designed with commercial clinical applications in mind, minimising the number of risk factors while maximising predictive accuracy.
Sex-specific factors – Incorporating sex-specific risk factors enhances model performance across diverse populations.
Superior performance – A multivariable risk assessment is shown to be superior to standard of care of family history assessment in its ability to predict risk of developing colorectal cancer.
'Significantly improve stratified screening'
Rhythm director of scientific affairs Dr Erika Spaeth said publishing the findings in PLoS One underscored its commitment to advancing cancer risk prediction.
'Our new multifactorial model outperforms previous methods based solely on polygenic risk and family history,' she said.
'By integrating clinical and lifestyle factors, we enhance our prediction accuracy for colorectal cancer.
'We're excited about these results and confident that this model will significantly improve stratified screening in the population."

Dutch defence chief warns Australia to increase military capability
The Netherlands' chief of defence has warned Australian leaders the country needs to counter China's military rise by increasing its own defence capability. General Onno Eichelsheim, visiting Australia for the Talisman Sabre defence exercises, warned the threat posed by China to the Indo-Pacific is not unlike that Russia poses to Europe. And he says "naivety" should not allow Australia and other countries to avoid preparing for the risk of conflict in future. "You should look at the facts that are around you … if Russia tells us that they want to have more, more influence, than take that seriously," he said. "And if you see in this case in this region, China building up, take it seriously and get ready for something that you hope will never happen. "If you prepare for war, you can avoid war. And that's how we look at it." The Netherlands recently agreed to lift its defence spending to 3.5 per cent of its GDP, alongside most other NATO countries. The decision came in part due to pressure from the United States for NATO countries to provide more for their own security. Australia has faced its own pressure from the United States to lift defence spending to the same level. General Eichelsheim said 3.5 per cent of GDP would provide the Netherlands with the capability the country needs, given the security situation in Europe. He said while the focus on GDP percentages was not important, there was no doubt Australia would need to do more. "It's not about the percentage, it's about the capabilities," he said. "But inevitably, I think Australia has to increase its capabilities as well, if you look at the region, and the build-up in this case of China. "Also, if they need to help out Europe, which [Australia is] actually already doing — if you look at the war in Ukraine, and supporting us there." In April General Eichelsheim issued an order to the country's 76,000 defence personnel, both uniformed and civilian. The top-ranking Dutch military official warned they needed to increase their readiness and be ready for rapid deployment. He said the message was sent for two reasons: that a ceasefire in the war in Ukraine might need to be protected, and that it might lead Russia to shift its attention elsewhere. "We know that [Russia has] the ability, if there is a ceasefire, they can move within one or two years to other locations where they can threaten, for instance, the Baltic States," he said. "So we need to be ready to defend that line as well. And that is not that much time, to be honest." The Netherlands is one of 19 countries taking part in the Talisman Sabre defence exercises, which are jointly organised by Australia and the United States. The Dutch defence personnel taking part are also joined by other European militaries like France, Germany and Norway. Asked why the Netherlands is taking an interest in the region, and how he views the security situation in the Indo-Pacific, General Eichelsheim said he has real concerns. "We worry about the amount of capabilities that China is building up," he said. "Those are not capabilities that you only use for protecting yourself. There are also quite a lot of offensive capabilities in it. "Leaving it only to the US versus China is also not a good idea — so we've increased our partnerships a lot with Japan, the Republic of Korea, Australia, New Zealand and also the Philippines." The Albanese government has pushed back on the United States' calls for significant increases in defence spending, arguing spending is already rising quickly. The prime minister has argued Australia will set its own defence policy, and made the case that specific capabilities should be funded, rather than funding targets set and pursued. Asked about whether pressure might come from other allies rapidly increasing defence spending as a share of GDP, Defence Minister Richard Marles said those countries can see what Australia is doing. "We understand there is a process of international benchmarking, but ultimately every country, when it goes through its own processes about what kind of defence force it needs to build, does so based on assessing its own strategic need," he said. "And that's exactly what we're doing and I think countries can see that we are engaging in that process, it's an ongoing process and a process which up until this point has yielded the biggest peacetime increase in Australia's defence spending."

As suitors circle Healthscope, its management mulls a different path
The sales process for Healthscope's failed private hospital business kicks off in earnest this Monday with up to 30 potential suitors due to file their tentative offers for its 37 Australian hospitals, employing 19,000 staff nationally. But the non-binding offers won't include a bid from Healthscope's current management, who are contemplating a scheme to convert the company into a not-for-profit entity. It would mirror the resurrection of Australia's largest child care provider Goodstart Early learning, from the ashes of the collapsed ABC Learning empire, as a not-for-profit provider. Healthscope insiders have confirmed reports in the Australian Financial Review last week that its chief executive, Tino La Spina, is working on the plan as an alternative to a sale of the business to either commercial interests or other Australian not-for-profit operators like St Vincent's Health Australia. Healthscope declined to comment. People with knowledge of the proposal, who are not authorised to discuss the matter, confirmed that the plans are not advanced enough to put in a non-binding indicative offer by the Monday, July 21 deadline. But La Spina's team have been consulting with the receivers from McGrathNicol who are managing the sale, with a view to putting in a proposal during the second stage of the sales process where interested parties are expected to lodge binding offers for the business. This includes local not-for-profit operators, ASX-listed Ramsay Health Care, privately owned Healthe Care and a potential debt-for-equity swap that could see lenders like UK-based Polus Capital take control. The receivers are acting for lenders which are owed $1.7 billion, according to documents lodged with the corporate regulator, the Australian Securities and Investments Commission (ASIC). Australia's Big Four banks are among the lenders which will be hit with significant losses as the sales price is not expected to get anywhere near what is owed to them. The debt includes $52 million owed to the former owner, Canadian financial giant, Brookfield, which had $2 billion in equity wiped out when the group collapsed into administration earlier this year.
