Ovarian cancer study identifies key genes for potential treatments
Around 7,500 women are diagnosed with high-grade serious ovarian cancer every year
A new study has highlighted the unique nature of ovarian cancer and the extent of variability between patients.
The study, conducted by researchers at Imperial College London, has confirmed that the tumours of some women with high-grade serious ovarian cancer (HGSOC) contain a type of lymphoid tissue, known as tertiary lymphoid structures or TLS, of which presence gives women a better prognosis.
They have also identified genes in high-grade serious ovarian cancer that are important for TLS formation and function.
The lymphatic system in our bodies helps fight off infection by producing immune cells such as T cells and antibodies. But TLS, which are in some ways similar to “normal” lymphatic tissues, are being found by researchers in different types of tumours.
By analysing tumours from 242 high-grade serious ovarian cancer patients before treatment and comparing them to progression free survival rates, the researchers found that women that had TLS in their tumours had a significantly better outcome.
The study, published in Cell Reports Medicine and funded by the National Institute for Health and Care Research Imperial Biomedical Research Centre, is one of the first times scientists have found TLS in women with high-grade serious ovarian cancer and linked them to a better outcome.
“People tend to think of all cancer cell activity as purely malignant, but the reality is less clear-cut,” explained lead researcher Dr Haonan Lu, from the Department of Surgery and Cancer.
“Tumours can hijack a number of normal body processes and here, they seem to be hijacking the formation of normal human lymph tissue within themselves. Some of these lymphoid structures are able to then mature and activate T cells, which could attack the cancer itself.”
Around 7,500 women are diagnosed with high-grade serious ovarian cancer each year. Due to late diagnosis, many experience disease relapse, leading to a five-year survival rate of below 40 per cent.
The researchers were able to pinpoint the relevant genetic mutations involved in the cancer’s TLS formation, some of which are known to have immune-suppressing functions.
The team found that copy number mutations in the genes IL15 and CXCL10 in HGSOC can inhibit the lymphoid tissue forming. They also found that another set of genes, including DCAF15, plays a role in interacting with the TLS tissues after they have been formed, probably making them more or less active.
Dr Lu said: “There is great potential for targeting these genes for benefits in ovarian cancer treatment. It’s now becoming clear how the genetic background of the tumour type interacts with a TLS to have more or less TLS function, and that will help us identify potential targets for therapy.”
The scientists have also, for the very first time, developed a potential method of identifying patients with high levels of TLS from standard CT scans, using AI. This could ensure that those women who would benefit from different treatments are found more quickly, they said.
Although CT scans form part of standard treatment of the condition, TLS tissues are not visible to the human eye from a normal CT scan.
However, the research team has developed an AI algorithm that was trained to detect the structures within the tumours and have successfully tested the algorithm on scans of patients at Hammersmith Hospital, known to have TLS tissues.
Professor Eric Aboagye, professor of cancer pharmacology and molecular imaging at Imperial College London, said: “This non-invasive identification test means that oncologists will be able to determine if a patient has high or low TLS in future and treat them accordingly.”
The researchers have now received a project grant from Target Ovarian Cancer to further investigate the relevant genetic mutations identified, and explore whether it is possible to activate anti-tumour immunity for all high-grade serious ovarian cancer patients.
A new Female Health Hub launched by the English FA will support women and girls in grassroots football in England with trusted advice on health issues affecting play.
The hub brings together expert-backed guidance, practical tools and player insights in one place, giving women and girls practical advice and reassurance on female health in football.
It has four core aims: to help women and girls better understand their bodies and how female health affects performance and participation, to educate players on key health topics and when to seek further advice or support, to provide practical strategies to help navigate common female health challenges, and to help break down taboos and normalise conversations around female health in football.
Users of the hub will also be able to hear directly from members of the England women’s national team, who share their own experiences of navigating female health matters while playing at the highest level of the game.
“Our ambition is to create a game where women and girls can thrive,” said Sue Day, the FA’s director of women’s football.
“To achieve that, it’s essential that players feel supported in environments that understand and respond to their female health needs.
“We’ve heard directly from grassroots players that they want better information and support around female health, but that they often don’t know where to find it.
“The launch of the Female Health Hub marks an important step in changing the landscape.
“We want every player to feel confident in her own skin and supported without judgment, so she can feel empowered by her body, rather than held back by it.”
The platform was launched following research conducted by the FA that highlighted the need for better education and support around female health in football.
According to the FA, 88 per cent of adult players surveyed said their menstrual cycle has an impact on their ability to train or play, but 86 per cent reported they had never received education about the menstrual cycle in relation to football performance and training.
The research also found 64 per cent of women experience issues related to sports bras or breast health while playing football, despite sports bras being considered one of the most important pieces of playing kit.
Players also expressed strong interest in learning more about injury prevention, at 87 per cent, nutrition, at 84 per cent, and mental health, at 77 per cent, in relation to female health.
The first phase of the Female Health Hub focuses on three of the most requested topics: menstrual health, breast health and injury resilience, with further content to follow, including nutrition and pelvic health guidance.
The Royal College of Midwives (RCM) has referred to the women’s health strategy as a ‘missed opportunity’ to address maternity services.
The renewed strategy was released by the government this week, with the aim of putting women’s experiences at the centre of care and ensuring they are “better heard and served”.
However, the government stated that because of ongoing investigations into maternity services across the country, the strategy “does not seek to address safety in maternity and neonatal services”.
The RCM described this as a “missed opportunity” and urged the government to ensure that, following the inquiries, maternity is placed “at the very heart” of the strategy.
Gill Walton, RCM chief executive, said the college was “deeply disappointed” that maternity services “do not feature as a headline priority” in the renewed strategy.
She said: “This is a significant missed opportunity and one that is very difficult to understand.
“Pregnancy, birth and the postnatal period are not a footnote in women’s health – they are one of the most significant and consequential phases of a woman’s life.
“A strategy that treats maternity as an afterthought is not truly a women’s health strategy at all. It is exactly the kind of thinking that has allowed maternity services to reach the point they are at today.”
Walton acknowledged that the strategy contained commitments on ensuring women’s voices shape their care, on supporting families through pregnancy loss and on the principle that services should be held accountable when they fail to listen to women.
She added: “But a strategy that addresses one part of women’s health while leaving maternity care behind is only doing half the job.”
Walton urged the government to ensure that this is addressed when the ongoing investigations into maternity care conclude, with any recommendations placed “at the very heart of this strategy with the seriousness and urgency that women, families and midwives deserve”.
In the foreword to the renewed plans, health and social care secretary Wes Streeting referred to the ongoing independent National Maternity and Neonatal Investigation as action being taken by the government to improve safety in maternity services.
The strategy also refers to the new National Maternity and Neonatal Taskforce, chaired by Streeting, which aims to help deliver “safer, more equitable care” for women, babies and families.
The foreword said that, because of ongoing initiatives, it was “important that this work continues without restriction and that the government can properly respond to the findings”.
It added: “This renewed women’s health strategy therefore does not seek to address safety in maternity and neonatal services other than that related to women’s health before and during pregnancy and the actions we are taking immediately to improve maternity and neonatal care.”
The strategy does, however, include plans to prioritise health education in schools, communities and healthcare settings to “empower women” with the “knowledge and tools they need to help control their fertility” and “prepare for the best pregnancy outcomes.
It also promises to provide women with access to “safe and high-quality contraception, abortion care, fertility services, preconception care and support after pregnancy loss in convenient settings.

For the majority of couples planning a pregnancy, genetic testing is not something they think about until a problem arises.
Pre-conception genetic carrier screening challenges this approach by identifying risk before pregnancy begins.
As panel sizes have grown and at-home testing options have become widely available, carrier screening is transitioning from a niche clinical referral into a mainstream component of reproductive planning.
What Carrier Screening Tests For
Being a carrier of a genetic condition means carrying one copy of a variant in a gene associated with that condition, without being affected by it.
In most cases, carriers are entirely unaware of their status.
The clinical significance of carrier status emerges when both members of a couple carry a variant in the same gene: in this scenario, each pregnancy carries a one in four chance of resulting in a child who inherits two copies of the variant and is affected by the condition.
The conditions most frequently included in expanded carrier screening panels include cystic fibrosis, spinal muscular atrophy (SMA), fragile X syndrome, sickle cell disease, and a range of metabolic and enzyme deficiency disorders.
The Beacon 787 carrier test, offered by Jeen Health, screens for 787 conditions from a single sample, making it one of the most comprehensive panels currently available to UK families.
Who Is Most Likely to Benefit
Any couple planning a pregnancy can consider carrier screening. It is particularly relevant for:
- Couples with a family history of a known inherited condition
- Those from populations with higher carrier frequencies for specific conditions, including Ashkenazi Jewish, South Asian and African communities
- Couples pursuing fertility treatment, where genetic information informs treatment planning
- Those who wish to have the most complete picture of their reproductive health before conception
Importantly, being a carrier of a condition does not mean a child will be affected. It means there is a defined statistical risk that can be quantified, discussed and planned for with appropriate clinical support.
How the Test Is Performed
Carrier screening is typically carried out on a blood or saliva sample.
For at-home options such as the testing offered by Jeen Health, a cheek swab collection kit is dispatched to the patient, the sample is returned by post, and results are delivered digitally within a defined turnaround period.
In-clinic carrier testing may use a blood draw and provides the advantage of immediate access to a clinical consultation at the point of result delivery.
London Pregnancy Clinic offers genetics counselling through its partnership with Jeen Health, allowing couples to receive and contextualise carrier test results with expert support.
Genetic counselling before and after testing is recommended by Genomics England as a standard component of any genomic testing pathway.
What Happens If Both Partners Are Carriers
If both partners are identified as carriers for the same autosomal recessive condition, they are typically offered further counselling to discuss their options.
These may include proceeding naturally with an awareness of the risk, using prenatal diagnosis (CVS or amniocentesis) during pregnancy to test the fetus, or pursuing preimplantation genetic testing (PGT) in the context of IVF, which allows unaffected embryos to be selected before transfer.
The purpose of identifying carrier status before pregnancy is to give couples time to consider these options without the added pressure of an ongoing pregnancy.
Knowledge of carrier status does not remove reproductive choices; it expands the information available when making them.
The Role of Pre-Conception Services
Carrier screening sits within a broader category of pre-conception care that includes fertility assessments, general health optimisation and, where relevant, management of existing conditions before pregnancy begins.
London Pregnancy Clinic offers pre-conception services encompassing fertility investigations, genetics counselling and carrier testing as part of an integrated 0th trimester approach, allowing couples to address genetic and clinical risk factors before their pregnancy starts rather than after.
