Measures prostate tumor volume and PSA density.
Why Use
Use physical measurements and PSA to calculate tumor volume and density.
Formula
Prostate volume in cc = L x W x H x π/6 [shape of ellipsoid] L in cm W in cm H in cm Prostate density = PSA / Volume
Advice
Tumor volume is used, along with the Gleason Score , to prognosticate prostate cancer recurrence. Tumor density helps distinguish between BPH and prostate cancer, used to determine the need for biopsy.
