Prostate Cancer Risk Calculator Available
On The Web
(February 2007)
The
NCI Early Detection Research Network offers a very straightforward
calculator that provides an estimate of the risk of a biopsy-diagnosed
prostate cancer, based on parameters of age, race, family history, PSA,
DRE, and prior prostate biopsy (yes or no). The risk of any grade
of cancer is given with a 95% CI, and also specifically provides an
estimate of the risk for high-grade cancer. The broad
application of this tool was validated by Ian Thompson et al. (UROLOGY
2006, DEC). In the validation study the "observed prostate cancer rates
increased with increasing PCPT [Prostate Cancer Prevention Trial] risk."
"Cancer was diagnosed in 15.7%, 39.0%, 48.8% and 100% of men for a PCPT
risk calculator value of <25%, 25% to 50%, 50% to 75%, and >75%,
respectively." The URL is

it can be more easily found as the first hit on Google by entering
"prostate cancer risk calculator."
