External Validation of the Briganti Nomogram to Predict Lymph Node Invasion in Prostate Cancer—Setting a New Threshold Value

Abstract: (1) Introduction: The study aimed to test and validate the performance of the 2012 Briganti nomogram as a predictor for pelvic lymph node invasion (LNI) in men who underwent radical prostatectomy (RP) with extended pelvic lymph node dissection (PLND) to examine their performance and to analyse the therapeutic impact of using a different nomogram cut-off. (2) Material and Methods: The study group consisted of 222 men with clinically localized prostate cancer (PCa) who underwent RP with ePLND between 01/2012 and… Show more

“…The significance of determining a cutoff value for a predictive model is to guide the physician during clinical decisions, but it also implies that a certain number of patients below that cutoff value may be missed. The current EAU guidelines suggest that the indication for ePLND is based on the risk of LN metastasis >5% using the Briganti nomogram ( 44 ). Using this cutoff, our model could spare about 50% (428/866) of ePLND and only 1.2% (5/428) of patients would be missed.…”

“…These findings imply that IL-17A and IL-17RA may play a significant role in the development of pre-metastatic niches, although further evidence is required to support this theory. These results could eventually assist in improving the accuracy of models such as Memorial Sloan Kettering Cancer Center (MSKCC), Partin, and Briganti nomograms, which are used to assess the likelihood of PCa nodal metastases [ 51 , 52 , 53 , 54 ]. The continuous improvement of methods to assess the risk of the presence of nodal metastases is very important because, despite the currently used tools, approximately 70% of patients undergo unnecessary extended lymphadenectomy, showing the absence of nodal metastases [ 55 ].…”

“…In the future, this observation may also be helpful in improving the models used to determine the risk of nodal metastases of PCa, such as the Briganti nomogram. This issue is extremely important in the decision-making process regarding the determination of the indications for lymphadenectomy, which significantly increases the risk of surgery and potential complications (12,(35)(36)(37).…”
