Better tests to define how aggressive a prostate cancer is needed, Cancer Research UK Cambridge Institute said, after it was reported that more than half of a group of men whose cancers were initially classified as slow-growing and confined turned out to have more dangerous tumours.
Urological surgeon Greg Shaw said:
This highlights the urgent need for better tests to define how aggressive a prostate cancer is from the outset, building on diagnostic tests like MRI (magnetic resonance imaging) scans, and new biopsy techniques which help to more accurately define the extent of the prostate cancer.
This would then enable us to counsel patients with more certainty whether the prostate cancer identified is suitable for active surveillance or not.
Whilst active surveillance would seem to be a safe approach for some men, nearly a third will end up needing surgery or radiotherapy within five years.
