Published in the journal European Urology, the study<\/a>, supported by National Institute for Health and Care Research (NIHR) infrastructure and a research fellowship, by researchers at Imperial College London and Imperial College Healthcare Trust is the largest of its kind. It reveals that ten years after focal therapy treatment, only 2 men out of nearly 3,500 in the study had died from prostate cancer. This very low mortality rate matches prostatectomy surgery and radiotherapy.\u00a0 <\/p>\nProstate cancer is the most common cancer in men, with more than 60,000 men diagnosed each year in the UK alone. Many of these cancers are confined to the prostate, and these men are offered either robotic surgery to remove the prostate (radical prostatectomy), or radiotherapy delivered to the whole prostate. Both are effective treatments but can cause long-lasting side effects, such as urinary incontinence and erectile dysfunction. These harms are one reason why the National Screening Committee recently advised against screening all men for prostate cancer.\u00a0 <\/p>\n
Far fewer side effects with focal therapy<\/p>\n
Around half to two-thirds of these localised cancers are suitable for focal therapy \u2013 that\u2019s up to 15,000 men per year in the UK. Focal therapy leads to a five-fold lower risk of side effects such as incontinence, erectile dysfunction and rectal problems compared to traditional radiotherapy or surgery because it only targets the areas of cancer. This minimises damage to healthy prostate tissue and those nerves and muscles next to the prostate which control urinary and sexual function.\u00a0 <\/p>\n
In this new study, the Imperial team worked with 14 hospitals across the UK to follow 3,477 men who had received focal therapy using a heat-based treatment (high intensity focused ultrasound, also known as HIFU) or a freezing-based treatment (cryotherapy) between 2004 and 2024. They discovered focal therapy effectively controlled prostate cancer, even in higher risk disease: <\/p>\n
Nine in ten men had intermediate or high-risk cancer \u2013 cancers that should not just be monitored, but should be treated
\n Ten years after treatment, just two men across the study had died from their prostate cancer (0.1%) and three in 100 (3%) had seen their cancer spread outside the prostate. These rates are similar to rates seen with surgery or radiotherapy treatment
\n One in three men needed further treatment, with some men choosing to have radical prostatectomy or radiotherapy even though they could have had further focal therapy. Out of those men who had two sessions of focal therapy, only one in ten needed to have prostatectomy or radiotherapy due to a persistent cancer. In comparison, 15-30% of men with similar prostate cancer risk who undergo prostatectomy or radiotherapy have cancer that recurs.\u00a0\u00a0<\/p>\n
Providing the evidence to underpin care for more men<\/p>\n
Focal therapy is already available at some NHS and private centres around the UK,\u00a0including Imperial College Healthcare NHS Trust. Focal therapy is approved by the\u00a0NICE HealthTech programme, as long as clinicians collect their data routinely for\u00a0outcomes in national registries. Awareness of the treatment has risen sharply over\u00a0the past year with several public figures recently speaking about undergoing focal\u00a0therapy.\u00a0\u00a0<\/p>\n
The study provides the evidence needed to underpin frontline care and strengthens\u00a0the case for more centres to offer focal therapy so more men can access it. As part\u00a0of its commitment to evaluate screening within the NIHR and Prostate Cancer UK\u00a0funded TRANSFORM study and ensure that harms of a future screening programme\u00a0are significantly reduced, the government announced \u00a32.8 million in capital funding\u00a0to expand focal therapy in line with the TRANSFORM trial expansion throughout the\u00a0UK.\u00a0\u00a0<\/p>\n
Study author Dr Alexander Light, NIHR Doctoral Fellow at Imperial College London\u00a0and urology registrar at Imperial College Healthcare NHS Trust, said: “The results of\u00a0our study are really encouraging. Ten years on, only two men in the study had died\u00a0from their prostate cancer and many men have benefitted from the treatment,\u00a0including men with more aggressive disease who would traditionally have been told\u00a0focal therapy wasn’t an option for them.”\u00a0<\/p>\n
Joint senior author Professor Hashim Ahmed, consultant urologist and Chair of\u00a0Urology at Imperial College London and Imperial College Healthcare NHS Trust, who\u00a0also leads the TRANSFORM screening study, said: “This is the largest and longest running study demonstrating that focal therapy delivers excellent long-term cancer\u00a0control across a broad range of patients. It makes a compelling case for more\u00a0centres to offer this treatment, and I am pleased to see the government make a firm\u00a0commitment of capital funding to support it. Right now, only about 1,000 men per\u00a0year have the treatment, when up to 15,000 men could – and are either not told\u00a0about it, or do not have local access.”\u00a0<\/p>\n
Joint senior author Dr Taimur Shah, consultant urologist and Associate Professor at\u00a0Imperial College London and Imperial College Healthcare NHS Trust, said: “Our\u00a0study now gives clinicians and patients the long-term evidence they have been\u00a0waiting for. We hope these results will help update the main NICE clinical guidelines\u00a0so that focal therapy is routinely offered as a first-line choice to men. Men who would\u00a0like to know whether it might be right for them can ask their urologist about referral to\u00a0a specialist centre that performs these treatments.”\u00a0<\/p>\n
Changing clinical practice as well as conversations<\/p>\n
Paul Sayer, Founder of the charity Prost8 UK, said: “I have benefited from focal\u00a0therapy myself, and this new study is incredibly significant. For too long, many men\u00a0have believed they had to choose between curing their cancer and preserving the\u00a0quality of their lives. This study shows that, for many patients, that simply isn’t true.” <\/p>\n
He continues: “At Prost8 we’ve helped hundreds of men understand their options and access specialist centres. Our hope is that this evidence marks the point where every suitable man is routinely offered focal therapy as part of his treatment choices, regardless of where he lives. This research shouldn’t just change clinical practice – it should change conversations in every consulting room across the UK. Every man deserves to know all of his appropriate treatment options before making one of the biggest decisions of his life.” <\/p>\n
Health Innovation and Safety Minister, Preet Kaur Gill, said: \u201cEveryone deserves access to the best possible treatment, and this government is determined to make that a reality. This study is a powerful demonstration of what focal therapy can achieve. Our investment of up to \u00a32.8 million, announced earlier this year, will help expand the TRANSFORM trial and ensure more men have access to this treatment through prostate cancer screening. Our National Cancer Plan sets out our ambition to transform cancer care, and backing innovations like focal therapy is exactly how we are delivering on that promise.\u201d <\/p>\n
Amy Rylance, Director of Health Services, Equity & Improvement at Prostate Cancer UK, said: \u201cThis is truly fantastic news for men. Side effects can be devastating, and this is the first long-term study that shows many men could avoid them without increasing the risk their cancer could return. These serious side effects are a major reason we don\u2019t yet screen for prostate cancer and reducing them makes it far more likely we can get to a screening programme for all men sooner.\u201d\u00a0 <\/p>\n
Imperial College Healthcare NHS Trust and Imperial College London are designated as a Focused Ultrasound Centre of Excellence. This is a prestigious network of just 16 centres worldwide who have been recognised by the Focused Ultrasound Foundation for advancing the development and adoption of focused ultrasound technology in research, training, and patient care. <\/p>\n
