PURPOSE OF REVIEW: With increasing adoption of minimally invasive surgical techniques in urologic oncology, the efficacy, safety, and adequacy of lymphadenectomy were reviewed for studies about prostate, bladder, kidney, upper tract urothelial, testicular, and penile cancer published in the past 18 months.
RECENT FINDINGS: In prostate cancer, in which robotic prostatectomy has become the predominant approach, use of extended lymphadenectomy has increased with lymph node yield nearing 20. Minimally invasive lymphadenectomy in bladder cancer does not yet approach the yield seen at high-volume open cystectomy centers, but a larger proportion of robotic lymph node dissections surpass the oncologic threshold of 10-14 lymph nodes compared with open surgery. Comparative lymphadenectomy data for kidney and upper tract urothelial cancers remain muddled as routine lymphadenectomy is not performed and both open and laparoscopic/robotic nephroureterectomy carry no consensus on templates. Minimally invasive retroperitoneal lymph node dissection carries safety and oncologic equivalence to the open technique only in limited centers, whereas minimally invasive ilioinguinal lymphadenectomy for penile cancer remains exploratory at this time.
SUMMARY: Findings from the prior year suggest that - in high-volume centers - lymph node dissection for urologic cancers is equivalent between open and minimally invasive techniques in lymph node yield and short-term to medium-term oncologic results.
