The Prostate Cancer Risk Calculators – including the ‘future risk’ calculator

Risk Calculator 1 – the general health calculator is a starting point, looking at family history, age and any medical problems with urination.

Risk Calculator 2 – the PSA risk calculator looks at the levels of prostate specific antigen (PSA) in patient’s blood to help predict whether further investigation is required.

Risk Calculator 3 and 4 with TRUS or DRE: Nowadays these risk calculators are combined into one decision tree and thus can be used for men that have not been previously biopsied but also for men that have been screened previously and had a prostate biopsy with a benign result.

There are two ways to include information on prostate volume, i.e. using data on prostate volume obtained during TRUS or using a DRE based prostate volume estimate which can be entered as 25, 40 or 60 cc.

Inclusion of prostate volume in the risk calculation gives a more accurate estimation of the risk of having a biopsy detectable (potentially aggressive) prostate cancer.

Available data can be entered step by step and on the basis of what is being entered the risk of having a biopsy detectable (potentially aggressive) prostate cancer is displayed.

Risk calculator 3 and 4 with TRUS or DRE and the result of the Phi test: Using these risk calculators gives you the possibility to include the outcome of the so-called Prostate Health Index (Phi) blood test which will slightly increase predictive capability.

Risk calculator 5 calculates the chance of having indolent prostate cancer which may not require immediate treatment.

Risk Calculator 6 is the latest in the series — it calculates a man’s future risk over the next four years, taking into account age, prostate-specific antigen, digital rectal examination, family history, prostate volume, and previous biopsy status.
