A prostate most cancers software measuring your danger stage might scale back deaths, based on consultants.
The chance of creating prostate most cancers is estimated by an algorithm primarily based on age, plus ranges of two prostate most cancers markers seen in blood.
There is not a single prostate most cancers check, but when profitable in future research, the brand new software could possibly be changed into a nationwide screening programme at some point.
At current, one of many first diagnostic instruments used is a blood check measuring prostate particular antigen (PSA) as raised ranges can signify an issue with the prostate, however the check is not supplied to all males.
It has beforehand been advised that screening on PSA ranges alone might result in extra males needing a prostate biopsy - the place a small pattern of cells are collected for additional examination - which might have unwanted effects.
Others have raised concern about 'overtreatment' of a lot of males who've gradual rising prostate most cancers that will by no means have affected them throughout their lifetime.
The brand new prostate most cancers screening software
The brand new examine, revealed within the Journal of Medical Screening, examined a brand new algorithm which examines a person's ranges of PSA and hK2 (human kalliknein peptidase) within the blood, in addition to taking into consideration their age.
The paper examined how properly the algorithm might predict prostate most cancers by evaluating blood samples of 571 males who later died after a prostate most cancers analysis with the blood samples of two,169 males by no means who had been by no means recognized with the illness.
The authors from UCL, Queen Mary College of London and St George's College of London, mentioned combining the blood checks with a danger evaluation software might imply that 90% of cancers are detected with 1.2% of circumstances deemed "false optimistic".
This methodology might assist to cut back the variety of false optimistic outcomes by three quarters, the authors added.
Lead creator Professor Sir Nicholas Wald, from the UCL Institute of Well being Informatics, mentioned: "A key disadvantage of screening for prostate most cancers utilizing a PSA check alone is the upper danger of a false optimistic, which might result in an pointless, invasive biopsy and the pointless remedy of a clinically insignificant most cancers that will not have brought about hurt anyway.

"Our examine exhibits a distinct screening strategy might scale back the variety of false positives by three quarters.
"This could make screening for prostate most cancers safer and extra correct, decreasing overdiagnosis and overtreatment.
"The following step is to check the feasibility of this strategy in apply with a pilot challenge inviting wholesome males for screening.
"If the challenge is profitable, we imagine this strategy should be thought-about as a part of a nationwide screening programme for all males."
Co-author Jonathan Bestwick, from Queen Mary College, added: "The strategy is revolutionary for most cancers, because it screens folks on the idea of their total danger fairly than the outcomes of a single check.
"This is identical strategy utilized in screening throughout being pregnant for sure foetal and maternal well being situations."
Commenting on the examine, Professor Roger Kirby, president of the Royal Society of Medication and vice-president of the charity Prostate Most cancers UK, mentioned: "This can be a novel strategy which utilises the degrees of two prostate most cancers markers, PSA and hK2 (human kallikrein peptidase) to refine prostate most cancers screening.
"Using PSA alone has vital drawbacks when it comes to screening, however the addition of the hK2 marker on this context carries the real promise of considerably decreasing the loss of life price from this most typical most cancers in males."
Simon Grieveson, head of analysis at Prostate Most cancers UK, added: "Catching prostate most cancers early can save lives, however with out a screening programme too many males will proceed to be recognized too late.
"Sadly, we at present would not have an correct sufficient check for use for a nationwide screening programme and so it is nice to see promising analysis like this in search of to create a greater check to detect prostate most cancers early.
"Within the meantime, males can discover out extra about their danger by utilizing Prostate Most cancers UK's danger checker, and may communicate to their GP if they've any considerations."
