Santeon mpMRI-based Nomogram to Predict Side-Specific Extraprostatic Extension
We developed a prediction model which can be used to accurately assess the likelihood of tumour extension outside the prostate. This tool can guide patient selection for safe nerve-sparing surgery.

Description of imput parameters:
PSA Density: most recent preoperative PSA level divided by prostate volume measured by TRUS or MRI
MRI (side-specific): no lesion (no lesion visible, PI-RADS <3), organ-confined (PI-RADS >2, but no EPE, EPE (lesion with reported EPE). *equivocal or uncertain EPE should be regarded as organ-confined
ISUP (side-specific): highest reported ISUP found on most recent preoperative biopsy
