Extended lymph node dissection for intermediate and high-risk prostate cancer： do we have all the evidence

In the article ＂extended lymph node dissection in robot-assisted radical prostatectomy： lymph node yield and distribution of metastases＂ published on Asian Journal of Andrology, Kim et al.1 present their robot-assisted experience for an extended pelvic lymph node dissection （E-PLND） in the management of intermediate and high-risk prostate cancer patients. The reported lymph node yield and positivity is comparable to literature published in robot-assisted and open approaches for radical prostatectomy.2 Increasing reports of a decline in the incidence of lymph node dissection,3 have questioned the adequacy of an E-PLND performed through the robot-assisted approach.
