Complications of pelvic lymph node dissection for prostate cancer

Area of Science:

• Urology
• Oncology
• Surgical Pathology

Background:

• Pelvic lymph node dissection (PLND) is a standard procedure for staging prostate cancer nodal metastases.
• It can be performed separately or during radical prostatectomy, offering diagnostic and potential therapeutic benefits.
• Debate exists regarding optimal candidates, extent, approach, and oncologic value of PLND.

Purpose of the Study:

• To review the complications associated with pelvic lymph node dissection (PLND).
• To inform the ongoing debate on the appropriate use and oncologic benefit of PLND in prostate cancer management.
• To highlight the importance of considering procedure-related morbidity.

Main Methods:

• Literature review focusing on complications of pelvic lymph node dissection (PLND).
• Analysis of reported complications including lymphocele, thromboembolic events, ureteral, nerve, and vascular injury, and lymphedema.
• Synthesis of evidence regarding the risk-benefit profile of PLND in different risk groups.

Main Results:

• Limited oncologic benefit of PLND is suggested in low-risk prostate cancer patients.
• PLND can be safely omitted in a significant proportion of men undergoing radical prostatectomy.
• The potential morbidity of PLND must be carefully weighed against its value, especially in intermediate- and high-risk disease.

Conclusions:

• The utility of PLND in prostate cancer requires careful patient selection to balance staging benefits against procedural risks.
• Complications such as lymphocele, thromboembolic events, and lymphedema are significant concerns.
• Further research and clinical judgment are needed to optimize PLND use and minimize patient morbidity.
