Australian researchers to develop new test for ovarian cancer
If successful, the test has the potential to improve early evaluation, speed up diagnosis and lower healthcare costs
Australian researchers are working on a new blood test to improve ovarian cancer diagnosis, with the potential to reduce unnecessary surgery.
The test, developed by scientists at Hudson Institute of Medical Research and commercialised by Cleo Diagnostics, will be underpinned by a novel biomarker, CXCL10, which is produced early and at high levels by ovarian cancers, but not in non-malignant disease.
The solution is hoped to accurately distinguish benign from malignant disease without surgical intervention. If successful, it has the potential to improve early evaluation, speed up diagnosis, lower healthcare costs and reduce stress and anxiety associated with a surgical diagnosis.
Ovarian cancer is the most lethal of all cancers affecting women in Australia. The current five year survival rate is 49 per cent and this has not changed substantively in 50 years.
Ovarian cancers are often indistinguishable from common, non-cancerous disease. Currently patients undergo a combined blood test and ultrasound to provide an assessment of disease.
However, experts argue neither is sufficient for an accurate diagnosis and they are only used for surgical referral.
As there is no accurate detection test for ovarian cancer, surgery to remove the ovaries remains the only way to diagnose the presence of malignant disease.
“There is often a delay in sending patients to a gynaecological oncology specialist for treatment, because defining whether a growth is likely to be malignant or not before surgery is very difficult,” explained Professor Tom Jobling, lead medical advisor at Cleo Diagnostics.
“This new test will help ensure that an optimal management plan can be put in place early, which will streamline the referral process and provide the best care for patients.
“This also extends to patients with benign conditions, where early identification will permit direction to more appropriate use of resources.”
Hudson Institute’s CEO, Professor Elizabeth Hartland, added: “Hudson Institute is delighted to be partnering with Cleo Diagnostics to take our work on ovarian cancer one step closer to delivering a much-needed diagnostic test.”
Initial clinical use of the test, the researchers have said, will focus on the surgical triage market to improve treatment outcomes for patients with ovarian cancer, and avoid unnecessary surgery and anxiety for women with far more common non-cancerous conditions.
Beyond surgical triage, Cleo Diagnostics will conduct further clinical trials to evaluate the effectiveness of the underlying core technology for disease recurrence following surgery, aiming to develop broader screening applications in the general population.
An early PET scan after one cycle of chemotherapy may help predict how aggressive breast cancer responds to treatment, a study suggests.
Research led by The Institute of Cancer Research, London and King’s College London suggests that an early scan taken after one cycle of chemotherapy could help predict how well a patient’s cancer will respond to treatment.
The study focused on patients with triple-negative breast cancer (TNBC), an aggressive form of the disease in which cancer cells lack receptors for the hormones oestrogen and progesterone, as well as the HER2 protein.
Patients with TNBC are usually treated with chemotherapy prior to surgery. While many respond well, residual disease at surgery, typically around six months later, is associated with a significantly poorer prognosis. Identifying people sooner who are unlikely to respond remains a major clinical challenge.
The research explored whether using PET imaging shortly after treatment begins, rather than relying only on MRI scans later in the treatment process, could provide earlier insight into how a patient’s cancer is responding. Twenty-two patients were recruited, with fourteen undergoing FDG-PET scans before treatment and after the first cycle of chemotherapy.
The findings, published in Clinical Cancer Research, showed that changes seen on PET scans after just one cycle of chemotherapy were strongly associated with subsequent response, including whether there was no detectable cancer, known as a complete response, by the end of treatment. Importantly, early PET response showed stronger associations with treatment outcomes than standard mid-treatment MRI scans in this study.
Being able to identify patients who are not responding well at an early stage could allow clinicians to adjust treatment sooner or consider alternative approaches. These findings may also support future strategies to better tailor treatment intensity to individual patients.
The study also compared two types of PET tracers, FDG and FLT, to determine which was most suitable. While both met the study’s technical criteria, FDG-PET was selected for further evaluation due to its better image quality, greater consistency and wider use in clinical practice.
The research also explored how imaging changes after just one cycle of chemotherapy relate to the body’s immune response to treatment. Biopsies taken before and after the first cycle of chemotherapy showed that an increase in immune cells within the tumour was strongly associated with both early PET changes and improved treatment outcomes.
The researchers emphasise that these findings now need to be validated in larger studies. Future work will aim to confirm these results in broader patient groups and explore more accessible imaging approaches, such as ultrasound, alongside PET and MRI.
Sheeba Irshad, professor of cancer immunology at King’s College London and lead of the Breast Cancer Now KCL Research Unit, said:
“In patients who had PET scans both before treatment and after the first cycle, we found that this early scan could predict whether they were likely to achieve a complete response by the end of treatment. These findings highlight the potential of early imaging to guide treatment decisions, and now need to be validated in larger, modern clinical trials.”
Andrew Tutt, professor of breast oncology at The Institute of Cancer Research, London, said:
“Research that helps us determine early who is already benefitting from standard neoadjuvant chemotherapy and who might benefit from clinical trials to find better treatments is vital. This study shows that FDG-PET may have great value in this regard. We hope to be able to design studies that further investigate and validate these findings.”
The study was supported by funding from King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, Breast Cancer Now, Cancer Research UK, and Guy’s and St Thomas’ Charity.

Startup of the Year Shortlist
Hello Inside is the first women’s health AI company to turn daily metabolic signals into outcomes women feel and healthcare systems reimburse.
Women’s health has long been under-researched, and current AI benchmarks fail on women’s health questions roughly sixty percent of the time.
Hello Inside built the architecture to close that gap.
Across four years and 12,000+ validated metabolic profiles, three in four women improve at least one symptom within ninety days.
They lose four kilograms in three months, moving from overweight into the healthy range. In a clinical study with Alisa Vitti’s Flo Living, 91.9 per cent reduced PMS burden within sixty days.
U-Ploid is an early-stage biotechnology company tackling one of the most fundamental challenges in fertility care: the sharp, age-related decline in egg quality that limits outcomes across IVF and egg freezing.
While much of the field focuses on improving assessment and selection, U-Ploid is developing a first-in-class therapeutic approach designed to improve egg quality itself by addressing the biological causes of age-related chromosomal errors.
Supported by strong preclinical evidence and now advancing into human studies, U-Ploid combines scientific rigour, regulatory discipline and long-term vision to help redefine what is possible in fertility care.
Gestational diabetes is a strong risk factor for future type 2 diabetes, even in women with normal pre-pregnancy weight, according to a study at the University of Gothenburg.
The researchers call for earlier testing and better follow-up.
“Our results show that gestational diabetes functions as a kind of stress test for the body’s ability to manage blood sugar, and identifies women with a greatly increased risk of future type 2 diabetes”, said Jon Edqvist, PhD and affiliated to research at the University of Gothenburg, and operating room nurse at Sahlgrenska University Hospital.
Gestational diabetes is a special type of diabetes that can affect pregnant women.
The condition is defined as elevated blood sugar levels, without previously known diabetes. Treatment involves self-monitoring of blood sugar, advice on lifestyle habits and, if necessary, medication.
Identifying gestational diabetes is important because the disease increases the risk of complications such as preeclampsia, the need for a cesarean section and high birth weight for the baby.
Those who have had gestational diabetes are also at higher risk of later developing type 2 diabetes.
In the current study, published in eClinicalMedicine, researchers now show that gestational diabetes is a strong indicator of future risk of developing type 2 diabetes, even in women with normal weight before pregnancy.
Elevated risk even with normal weight
The study is based on data from the Medical Birth Registry on just over 1.15 million first-time mothers in Sweden, who gave birth between 1987 and 2019. 16,870 women with confirmed gestational diabetes were compared with age-matched women without the diagnosis. The median follow-up period was nine years.
The results show that women with a BMI of 35 and above, i.e. severe obesity, had an almost tenfold increased risk of developing gestational diabetes compared to women with normal weight.
The risk of subsequent type 2 diabetes also increased with higher BMI, but it was significantly increased even with normal weight, which the researchers describe as particularly worrying.
More follow-up and more studies
The researchers behind the study welcome the recently updated recommendations on gestational diabetes in Sweden, where a higher proportion of pregnant women at increased risk are expected to be offered testing earlier in pregnancy, and if necessary, interventions.
“Diagnostics and care of gestational diabetes have looked very different in different parts of the country,” said Annika Rosengren, professor at the University of Gothenburg.
“There is a need for both improved follow-up after gestational diabetes, and more studies that investigate how such follow-up affects future health and prognosis”
