‘Huge Leap’ In Prostate Cancer Testing

The biggest leap in diagnosing prostate cancer “in decades” has been made using new scanning equipment, say doctors and campaigners.

Using advanced MRI nearly doubles the number of aggressive tumours that are caught.

And the trial on 576 men, published in the Lancet, showed more than a quarter could be spared invasive biopsies, which can lead to severe side-effects.

The NHS is already reviewing whether the scans can be introduced widely.

Prostate cancer is the most common cancer in men, and yet testing for it is far from perfect.

If men have high prostate-specific antigen (PSA) levels in the blood, they go for a biopsy.

Twelve needles then take random samples from the whole of the prostate.

It can miss a cancer that is there, fail to spot whether it is aggressive, and cause side-effects including bleeding, serious infections and erectile dysfunction.

“Taking a random biopsy from the breast would not be accepted, but we accept that in prostate,” said Dr Hashim Ahmed, a consultant and one of the researchers.

Around 100,000 to 120,000 men go through this every year in the UK.

Scanning

The trial, at 11 hospitals in the UK, used multi-parametric MRI on men with high PSA levels.

It showed 27% of the men did not need a biopsy at all.

And 93% of aggressive cancers were detected by using the MRI scan to guide the biopsy compared with just 48% when the biopsy was done at random.

Dr Ahmed, who works at University College London Hospitals, told the BBC News website: “This is a significant step-change in the way we diagnose prostate cancer.

“We have to look at the long-term survival, but in my opinion by improving the detection of important cancers that are currently missed we could see a considerable impact.

“But that will need to be evaluated in future studies, and we may have to wait 10 to 15 years.”
