Abstract
We evaluated and described the impact of prostatic indocyanine green (ICG) injection on extended pelvic lymph node (LN) dissection (ePLND) in robotic-assisted radical prostatectomy (RARP). Between January 2019 and December 2021, we included consecutive 50 PCa patients who underwent ePLND during RARP with (n = 25) or without (n = 25) prostatic ICG injection. ICG injection was performed during abdominal port placement and robot docking. Pelvic LNs reflecting green color were initially excised and then the template was completed. The outcomes of two groups were compared. Overall, nine (36%) and five (20%) of the patients had metastatic LN involvement in the ICG and non-ICG groups, respectıvely. Of the 509 dissected LNs in the ICG group, 122 (23.9%) were fluorescence active. 20 LNs (3.9%) were metastatic in this group, 9 (45%) of which were ICG+. 408 LNs were resected on the non-ICG group with 8(1.9%) being metastatic. Eight (88.9%) of nine pN+ patients were florescent positive in the ICG group. Out of six patients with pN+ disease, Ga68 PSMA-PET/CT detected positive LNs preoperatively. In addition to preoperative Ga68 PSMA-PET/CT investigation, ICG-guided ePLND might increase identification and removal of metastatic LNs duirng RARP. Improvements ın stagıng and oncologıc outcomes may also be seen ın intermediate- and high-risk patients.
