Trials of a new treatment for prostate cancer have produced very positive results. With further testing, it may pave the way for a new treatment that radically reduces unpleasant side-effects.
The new method, called HIFU (high-intensity focused ultrasound), uses sound waves to selectively target individual cancer sites in order to burn away the cancerous cells without affecting the surrounding area.
Current treatment - whether surgery or radiotherapy - leaves many men with serious and embarrassing side-effects including incontinence and infertility. The proportion of men who experience such side-effects after surgery is as follows:
- Up to 25% are incontinent
- Up to 75% can't get an erection
- Up to 10% have problems like diarrhoea
- Only 50% manage to avoid one of those three
More than 37,000 men are diagnosed with prostate cancer in the UK each year, and approximately 10,000 of those cases are fatal.
ITV News' Medical Editor Lawrence McGinty visited University College Hospital in London to watch a demonstration of the new technology. In this video, Professor Mark Emberton talks him through the treatment:
In trials of the new treatment, funded by the Medical Research Council, none of the 41 men taking part had incontinence of urine and just one-in-ten suffered from poor erections a year after treatment. The vast majority (95%) were also cancer-free after a year.
Dr Hashim Ahmed, who led the study, said:
The Prostate Cancer Charity welcomed the research, but warned that the tests were still at an early stage.
Lawrence McGinty also spoke to Bob Louth of Romford, London who took part in the trial. He said he was deeply impressed with the treatment he received.
