Cervical screening progress at King's
New technology helping to save lives in the fight against cervical cancer
Women across Bromley, Bexley, and Greenwich are benefitting from new technology which is preventing cervical cancer and helping women who wish to have a family.
Doctors at Orpington Hospital in the London Borough of Bromley are using a new screening device called a DySIS to help detect changes in a woman’s cervix and to help guide the best course of treatment to prevent them developing cancer.
The digital technology helps to pick up changes to cells which could go on to become cancerous. The advanced cervical scan is also ensuring women do not undergo unnecessary invasive treatment, which can in some cases leave them with problems during pregnancy, such as increased risk of premature birth.
Doctors have said the device is helping around a thousand women a year at the hospital and has changed the philosophy of how women are treated.
Mr Adeyemi Ogunremi, consultant gynaecologist and lead colposcopist for Princess Royal University Hospital (PRUH) and Orpington Hospital, part of King’s College Hospital NHS Foundation Trust, said the device is helping to save lives: “This technology moves things up a notch from standard techniques by using digital imaging. It enhances what I see by generating a digital map at the end of the examination.
“Now we can see pre-cancerous hot spots with increased accuracy which might not have been picked up before, which is the unique thing about it. The new technology can help to detect abnormal cells earlier, particularly the ones which need treating, to avoid women going onto develop cervical cancer.”
Women are referred to Orpington Hospital for a procedure called a colposcopy – a detailed examination of the cervix (neck of the womb) – after they have had an abnormal cervical screening test (known as a smear), which requires further investigation.
Around a thousand women attend the hospital each year to have a colposcopy procedure, and of these women, Mr Ogunremi estimates that 60% have pre-cancerous changes. He believes a proportion of those would go onto develop cancer if they were left untreated.
Mr Ogunremi said the device is improving accuracy for both clinicians and patients and should be part of a modern state-of-the-art colposcopy service. He added: “It is extremely important that women attend their cervical screening tests. They can indicate abnormal changes, which we can then investigate further and treat where necessary to prevent cervical cancer.”
Meanwhile, in 30% of women with mild pre-cancerous changes, the abnormal cells could regress naturally without treatment, which itself carries side effects that can impact on a woman’s fertility in some cases.
“The treatment is not without its down sides; it carries a risk and can cause premature birth in women who go on to become pregnant,” said Mr Ogunremi. “The majority of the patients we see are young women who have not yet started a family. Fertility is an important topic and not treating them if they don’t need to be is key.
“This screening tool gives us increased accuracy and enables us to confidently reassure women when they do not need treatment. In the past we would have been seeing these women again and again, which creates more anxiety for the patient. Now we can confidently reassure them what the best course of treatment is during their first visit.”
The DySIS – Dynamic Spectral Imaging System - uses digital imaging to show doctors in real time on a screen where pre-cancerous cells are in a woman’s cervix and helps to map and measure what level the changes are so doctors can decide on the best level of treatment.
DySIS enhances the degree of accuracy of traditional colposcopy which means that treatment can be given in a much more tailored fashion to the individual woman. It records the whole examination and archives it so doctors have a permanent digital record. Patients can look at the screen if they wish during the examination which makes the procedure easier for them to understand.
Orpington Hospital is one of several hospitals across the country using DySIS.
Heather Holyoak, 30, a final-year medical student who lives in Bromley, has had three colposcopy procedures and a biopsy in the last three years after she had abnormal smear test results. The student has been diagnosed with Human Papilloma Virus (HPV), a group of viruses that affect a woman’s cervix. HPV is common, with over three quarters of sexually active women acquiring it at some time in their lives. HPV can cause changes to cells within a woman’s cervix, which can lead to cervical cancer.
Talking about her experience, Heather said: “I was told I had the worst strain of HPV. I went for a colposcopy and I was scared I had cancer. They took a biopsy and it came back clear.”
Heather has been back each year for colposcopies as a result of abnormal smears and has had the DySIS colposcopy procedure. She added: “It was really good to be able to see the screen and feel a little more in control and understand what was happening.
“Doctors don’t want to take a risk with people’s lives. With DySIS and its increased accuracy they can reassure women with confidence they don’t need the invasive treatment, which is great for younger women who want to start a family.”
So far, Heather has not had to undergo treatment. She wants to raise awareness of the Cervical Cancer Screening Programme and the HPV Vaccination Programme, which both help to prevent cervical cancer. “HPV is so common and is the leading cause of cervical cancer. The majority of women will have it at some point in their lives. The screening programme, subsequent colposcopy and therefore DySIS are so important. I really want people to understand how easy and simple the colposcopy was, and for me it wasn’t remotely painful or uncomfortable, and it could be something that puts your mind at ease until the next smear.”
About 3,000 cases of cervical cancer are diagnosed each year in the UK. It's possible for women of all ages to develop cervical cancer, although the condition mainly affects sexually active women between the ages of 30 and 45. The condition is very rare in women under 25.
