Novel Briganti nomogram: Predicting the risk of lymph node involvement in prostate cancer patients
Development and Internal Validation of a Novel Model to Identify the Candidates for Extended Pelvic Lymph Node Dissection in Prostate Cancer.​​​​​

Several previous nomograms have been developed by Briganti et al. that predict a patients risk of lymph node involvement. This model is an update of the Briganti nomogram and showed a better performance than the previous Briganti nomogram. This model added the percentage of biopsy cores with highest grade PCa and lowest grade PCa as new predictors to the prediction of lymph node involvement.

Conditional information

An extended pelvic lymph node dissection (ePLND) should be avoided in patients with detailed biopsy information and a risk of nodal involvement below 7%, in order to spare approximately 70% ePLNDs at the cost ofmissing only 1.5% lymph node invasions.
