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.

Pregnant women’s expectations about postpartum sleep may predict sleep quality after birth, outweighing prior sleep and psychiatric history, a study suggests.
The findings suggest attitudes and beliefs about sleep during pregnancy could be a modifiable risk factor for postpartum sleep concerns.
They also indicate that, among women expecting the poorest sleep, higher postpartum anxiety may further worsen sleep quality.
Sammy Dhaliwal, lead author is clinical health psychologist and research fellow in the department of obstetrics and gynaecology at the Perelman School of Medicine at the University of Pennsylvania.
Dhaliwal said: “Most pregnant women in our sample anticipated poor postpartum sleep before it occurred, and it was striking that those expectations predicted worse sleep outcomes even after accounting for factors such as prior sleep disorders, psychiatric history, and number of previous births.
“This suggests that attitudes and beliefs about sleep during pregnancy may represent a modifiable target for early intervention before postpartum sleep problems emerge.”
Sleep disturbance affects an estimated 60 to 80 per cent of postpartum women and is linked to a higher risk of depression and anxiety.
Researchers said it is often regarded as an expected part of life after childbirth rather than a health issue that may be addressed earlier.
The study enrolled 432 pregnant women at about 24 weeks of gestation, meaning around 24 weeks into pregnancy.
Participants completed measures of their expectations about postpartum sleep, current sleep quality using the Pittsburgh Sleep Quality Index, and mood using validated depression and anxiety scales.
Assessments were repeated at six, 12 and 24 weeks postpartum.
A subset of 49 women also wore wrist actigraphy devices at six to eight weeks postpartum.
Actigraphy uses a wearable device, similar to a watch, to estimate sleep and wake patterns based on movement.
The results showed that 70 per cent of pregnant women, or 301 of 432 participants, expected poor sleep in the postpartum period.
Researchers found that predicted sleep disruption during pregnancy was a significant predictor of postpartum sleep concerns.
Among first-time pregnant women without prior health concerns, those who expected greater sleep disturbance had significantly more disrupted sleep after birth, measured by both actigraphy and self-report.
Among women who expected the worst sleep quality, higher postpartum anxiety significantly worsened both measured sleep and self-reported sleep, independent of anxiety levels during pregnancy.
Dhaliwal said the findings point to two possible areas for intervention: addressing sleep-related beliefs during pregnancy and treating postpartum anxiety.
Dhaliwal said: “Postpartum sleep disruption is often treated only after problems develop, but our findings suggest there may be an opportunity to intervene earlier during pregnancy.
“Addressing sleep-related beliefs and postpartum anxiety during prenatal and postpartum care may help improve sleep and emotional well-being in new mothers.”
A weight loss jab may improve fertility outcomes in women with PMOS, early findings from an ongoing clinical trial suggest.
The proof-of-concept analysis found that injectable semaglutide may offer reproductive benefits while also addressing obesity and metabolic dysfunction.
It is the first report to examine how injectable semaglutide may improve reproductive outcomes in women with PMOS while also addressing obesity and metabolic dysfunction.
The work forms part of the ongoing RESTORE clinical trial.
Melanie Cree, professor at CU Anschutz and first author of the report, said: “Women with PMOS frequently face a frustrating choice between treatments that target reproductive symptoms and those that address metabolic health.
“Our early findings suggest injectable semaglutide may have the potential to improve both, offering a more comprehensive approach to care.
“This medication is incredibly promising when someone responds with 10 per cent weight loss.”
The trial is examining whether semaglutide can restore ovulation and improve reproductive health in adolescents and adults with polyendocrine metabolic ovarian syndrome, known as PMOS.
PMOS, formerly known as polycystic ovary syndrome or PCOS, is a hormone and metabolic condition linked to irregular periods, raised testosterone levels, infertility risk, obesity and increased cardiometabolic disease.
Cardiometabolic disease refers to conditions linked to the heart and metabolism, such as heart disease, high blood pressure and type 2 diabetes.
Existing treatments, including metformin and hormonal contraceptives, often do not fully address reproductive and metabolic complications at the same time.
The analysis focused on participants aged 12 to 35 who lost at least 10 per cent of their body weight during treatment.
Researchers said reproductive improvements appeared earlier than expected, prompting them to report preliminary findings while the wider study continues.
Cree is also a paediatric endocrinologist at Children’s Hospital Colorado.
Endocrinologists are doctors who specialise in hormones and hormone-related conditions.
Cree said: “What makes this work particularly important is that it focuses specifically on women with PMOS receiving injectable semaglutide.
“Although GLP-1 medications have transformed obesity treatment, there remains a significant need for rigorous data examining how these therapies affect fertility and reproductive function in this population.”
The RESTORE study is evaluating semaglutide treatment in girls and women with PMOS and obesity.
Its broader aim is to determine whether weight loss and metabolic improvements can restore ovulation and improve reproductive outcomes.
Ovulation is the release of an egg from the ovary, a key part of the menstrual cycle and fertility.
The authors said the findings are from an early proof-of-concept analysis and that larger, longer-term studies will be needed to confirm whether the reproductive benefits last.
The findings suggest injectable semaglutide may become a treatment option for women with PMOS seeking improvements in both metabolic and reproductive health, if future studies confirm the results.
