‘Outdated guidance' sees thousands at risk of prostate cancer ‘overtreatment'
Experts suggest closely monitoring certain patients can be the 'best' option for men whose cancer is unlikely to progress, although out-of-date guidance from the National Institute of Health and Care Excellence (Nice) on how this is implemented has created a 'wild west'.
There are around 55,000 new cases of prostate cancer diagnosed in the UK every year.
However, in some cases, the cancer is slow-growing and unlikely to ever cause the patient harm.
These men benefit from being closely monitored with blood tests and scans, which is known as active surveillance.
Nice guidance on active surveillance is designed to advise specialists on how to implement monitoring and which men should be monitored.
However, it has not been updated since 2021, according to Prostate Cancer UK.
Freedom of information (FOI) request analysis by the charity found around one in four (24%) of hospitals rely on Nice guidance alone to implement active surveillance.
It also found 35 hospitals have created their own guidelines, which Prostate Cancer UK warned can lead to inconsistency and confusion among medics.
The charity is now repeating its call for Nice to update its guidance on active surveillance, claiming it could help up to 5,000 men a year avoid overtreatment.
It also claims the outdated guidance is hindering a screening programme for prostate cancer.
Amy Rylance, assistant director of health improvement at Prostate Cancer UK, said: 'To reduce the harm caused by prostate cancer and build the foundations for a screening programme, we need to both save lives and prevent unnecessary treatment but official guidelines still haven't caught up with the clinical evidence.
'Concerns about overtreatment are a major reason the UK does not routinely screen for prostate cancer, despite it being the most common cancer in England.
'Acting on latest research that shows more men can safely opt for monitoring instead of treatment will reduce overtreatment and the harm it causes men.
'We asked Nice to update their active surveillance guidance two years ago, but our request was rejected. Now we have evidence this is potentially affecting thousands of men. Enough is enough.'
The NHS uses a prostate-specific antigen (PSA) blood test to check for prostate conditions including prostate cancer or an enlarged prostate.
Routine PSA testing is not currently offered on the NHS, but patients may be offered a PSA test if a GP suspects they have prostate cancer, while men over 50 can request a test from their GP even if they do not have symptoms.
However, there have been calls to roll the test out across the health service, although some argue widespread use could identify cases which may not have caused problems or needed treatment.
Vincent Gnanapragasam, a professor of urology at the University of Cambridge, said: 'Active surveillance is the best treatment option for men whose cancer is unlikely to progress or cause them problems in their lifetime.
'But Nice's outdated guidelines have created a deeply concerning wild west on how surveillance is implemented by different healthcare teams.
'This inconsistency is resulting in a lack of confidence from patients in surveillance, who may instead opt to have treatment they may not have ever needed, risking harmful side effects.
'Programmes for active surveillance that are standardised and individualised to a man's risk factors have been tested and proven to work.'
The UK's National Screening Committee is currently assessing whether a national screening programme for prostate cancer should be rolled out.
A Nice spokesperson said: 'We are committed to ensuring our guidelines continue to reflect the best available evidence and give patients the best possible outcomes.
'They are developed by an independent committee, including NHS clinical experts, and are kept under review to ensure they remain current.
'We are updating our prostate cancer guideline, including a review of the recommendations around active surveillance, and will be assessing whether our suspected cancer guideline recommendations around age-related thresholds for PSA tests for prostate cancer for onwards referral from primary care require updating.'

Pensioner, 77, died during heart surgery when hospital suffered a ten-minute power cut during a crucial stage, inquest hears
A pensioner died during heart surgery at an NHS hospital after the operating theatre she was in suffered a ten-minute-long power cut, an inquest heard. Jean Dye, 77, was at the crucial stage of the procedure when the electricity went down - meaning doctors had to delay the process as they couldn't see vital X rays. Five years after her death, a coroner has now issued a report saying that the delay in restoring power was a 'critical factor in her death'. It was found that an engineer was required to reset the system because it was in another part of the hospital. In a Prevention of Future Deaths Report, Paul Smith, Senior Coroner for Greater Lincolnshire, has now raised concerns about the lack of power controls within the operating theatre and that medical professionals weren't trained in how to understand when electricity has been restored. Mrs Dye, from Grimsby, Lincolnshire, suffered an underlying cardiac disease and attended Scunthorpe General Hospital to have it treated, the inquest was told. At the time of her death in September, 2020, she was having stents implanted to treat narrowed blood vessels. The operation only has a limited window to deploy the devices, the hearing was told. However, at exactly this moment there was a 'sudden and unexpected' power cut, which lasted for 10 minutes. It meant that medics could not see X-rays they needed for the procedure. No clear cause for the power cut has been identified, other than it overrode the back-up electrical supply, Mr Smith said. It was confirmed that power cuts have occasionally happened at hospitals across the country but the staff in Scunthorpe had not had this happen before. There was no manual re-activation of the circuit meaning that an engineer had to come to fix the issue. Once the power had returned, the stenting was completed but Mrs Dye failed to recover and she later passed away, the inquest heard. The hearing concluded that 'on the balance of probabilities, Mrs Dye would have survived but for the loss of electrical power'. It gave her cause of death as an iatrogenic artery dissection during a percutaneous coronary intervention. Mr Smith raised concerns about the lack of an indicator within the lab to confirm that the power had re-activated. There were also issues with the reset button being elsewhere in the hospital. Mr Smith said: 'The delay whilst power was restored was a critical factor in this death. 'The loss of power arose as a result of the Emergency Power Off (EPO) circuit activating. It overrode the emergency power back up system. 'All staff at the scene were unaware of the cause of the loss of power, never having experienced such a situation previously, and an engineer was summoned to attend to reinstate the power, which he did. 'There was no light or other indicator within the lab to confirm to those present that the EPO circuit had activated. Likewise there was no restart button within the lab to permit the EPO circuit to be reset. That lay within the plant room elsewhere within the hospital. 'Had staff been aware of the exact cause of the loss of power on this occasion and had they had the opportunity to reset the circuit without the need to await the arrival of an engineer, who in turn had to attend a separate plant room, the downtime would likely have been significantly reduced. 'Whilst it was not possible to say that the additional time spent on this occasion made a difference between the patient surviving or not, there may well be future cases within which such fine margins are time critical. 'I received evidence that there is no current guidance in relation to the siting of such controls remote from the affected room. I invite review of that guidance and of the need for any consequential training.' Mr Smith sent the report to NHS England and the Health Service Executive, who have until August 28 to respond.

Tributes as former Birmingham doctor dies aged 95
Tributes have been paid to a "trailblazer" former doctor who has died at the age of Pauline Manfield became one of the first female consultants in UK paediatrics, helping establish a department at the Good Hope Hospital in Sutton Coldfield, with her colleague, staff nurse Eileen leaving the NHS in her 60s, devout Christian Dr Manfield became a lay reader and chaplain at Birmingham Cathedral where she served until she reached her late Hospitals NHS Foundation Trust said she "leaves behind a legacy defined by compassion, dedication, and an unwavering commitment to service". Dr Manfield was born in Worcester in 1929 and her early years were shaped by World War Two, especially the vivid memories of bombings during her time in Preston as a family eventually settled in Chelmsford where she attended Chelmsford Girls' High an aspiration to become a doctor, she studied medicine at The Royal Free Hospital. She then went on to earn membership of the Royal College of Physicians in the 1960s before joining Good addition to her work with the NHS and Birmingham Cathedral, she was a member of Sutton Sisters, a local multi-faith group promoting understanding and unity. She was involved with a range of local groups, such as the Sutton Coldfield Archaeological and Gardening Societies, and the Lichfield Science and Engineering also ran in the Sutton Coldfield Fun Run, enjoyed photography and travel, and was a regular at ballet shows and Birmingham Symphony Orchestra Manfield also led efforts through the Sutton Coldfield Association of Women Graduates to sponsor young women in Malawi. 'Deep compassion' "Her intelligence and warmth earned her early praise as 'clever, pretty and kind' – a description that would remain true throughout her long life," a spokesperson for the NHS Trust said."Pauline was known not only for her clinical excellence but also for the deep compassion she showed to patients and their families."Her impact was so significant that many former patients contributed to a special birthday book in her honour, filled with notes of gratitude and stories of lives touched by her care."While she never married or had children, the spokesperson said "Pauline nurtured deep friendships and maintained connections with her schoolmates and colleagues"."She was godmother to 12 children, and her home in Sutton Coldfield was a hub of hospitality, known for its garden parties, home-cooked meals, and walls lined with decades of photographs," the spokesperson continued."Pauline will be remembered as a trailblazer, a mentor, and a kind-hearted physician who gave her all to the people and causes she believed in."

Struggling to sleep? Your gut bacteria could be to blame
Your gut health can impact everything from your mood to your immune system, but it could also be the cause of your poor sleep, a study has found. Specific types of gut bacteria have been linked to insomnia risk by researchers, while insomnia itself has also been linked to an abundance of certain 'bugs' in the gut. Insomnia, which means a person has difficulty falling and staying asleep, affects about a third of adults in the UK. It can be caused by anxiety, noise, alcohol, caffeine or shift work, according to the NHS. Several studies have explored the effects of the gut microbiome on various sleep characteristics, but it's not yet clear how different groups of gut bacteria might affect the risk of insomnia. The study, published in the journal General Psychiatry, used data on 386,533 people with insomnia from a previously study, gut microbiome data for 18,340 people from the MiBioGen alliance and for 8,208 people from the Dutch Microbiome Project with 71 groups of bacteria in common. Their analysis revealed associations between specific gut microbes and insomnia. Overall, a total of 14 groups of bacteria were positively associated with insomnia and eight groups showed a negative association. Insomnia itself was associated with a reduction of between 43 per cent and 79 per cent in the abundance of seven groups of bacteria and a 65 per cent to a more than fourfold increase in the abundance of 12 other groups. Researchers found the Odoribacter class of bacteria, in particular, was significantly associated with the risk of insomnia. This type of bacteria plays a role in producing short-chain fatty acids like butyrate, which in the right levels can help maintain a healthy gut. However, there are some limitations to the study. All the study participants were of European descent, so the results may not be more widely applicable as the make-up of the microbiome varies among different ethnicities and geographies, researchers point out. Diet and lifestyle – which affect the microbiome – were also not accounted for. Although bacteria are linked to insomnia, those same bacteria may be shaped by a person's eating habits, stress levels, and environment. 'Overall, the intertwined effects of insomnia on gut microbiota, and vice versa, represent a complex bidirectional relationship involving immune regulation, inflammatory response, release of neurotransmitters, and other molecular and cellular pathways,' study authors said. The authors conclude: 'Our study offers preliminary evidence supporting a causal effect between insomnia and gut microbiota, providing valuable insights for the future development of microbiome-inspired treatment plans for insomnia.' These treatment plans might include the use of probiotics, prebiotics, or faecal microbiota transplantation, they suggest.
