Risk of Positive Pelvic Nodes


This is the Briganti nomogram that predicts the likelihood of positive pelvic nodes based on information from a prostate biopsy only. Enter the details below for a specific patient who has had a biopsy for prostate cancer, and this tool will estimate the probability of finding at least 1 positive pelvic node if the patient has an extended pelvic lymphadenectomy.
