Multicenter StudyExternal validation of the updated nomogram predicting lymph node invasion in patients with prostate cancer undergoing extended pelvic lymph node dissection.
The aim of our study was to determine the validity of the updated nomogram [Briganti et al.: Eur Urol 2012;61:480-487] as a prediction tool for pelvic lymph node invasion (LNI) in the current era by using a large multicentric population of men who underwent extended pelvic lymph node dissection (ePLND) at the time of radical prostatectomy (RP) at tertiary referral centers. ⋯ The updated nomogram predicting LNI in patients with PCa undergoing ePLND has been externally validated, demonstrating excellent accuracy and calibration characteristics and a general applicability for predicting the presence of LNI.
