Salvage lymphadenectomy in postprostatectomy patients with prostate-specific antigen recurrence

Area of Science:

• Urology
• Oncology
• Radiology

Background:

• Radical prostatectomy offers good outcomes for organ-confined prostate cancer, but up to 40% of patients experience biochemical recurrence (BCR).
• Identifying the precise site of BCR, whether local or distant, is challenging with traditional imaging.
• Advanced imaging like PET/CT scans can detect small recurrence sites, potentially enabling new treatment strategies.

Purpose of the Study:

• To review the current evidence on salvage lymph node dissection (SLND) for patients with biochemical recurrence of prostate cancer.
• To evaluate the efficacy and patient selection for SLND in cases of nodal recurrence detected by PET/CT.

Main Methods:

• Review of studies investigating selective pelvic/retroperitoneal lymph node dissection in patients with BCR and PET/CT-identified nodal uptake.
• Analysis of reported outcomes, including prostate-specific antigen (PSA) response and surgical benefits.

Main Results:

• Conflicting results exist regarding the benefit of SLND; some patients show temporary PSA response, while others do not.
• The identification of suitable candidates for SLND remains a challenge.
• Some studies report partial or complete PSA response to SLND in nodal recurrence, but with limitations.

Conclusions:

• Current data on SLND for prostate cancer nodal recurrence are limited by small patient numbers, lack of control groups, and short follow-up.
• The available evidence does not currently support the routine use of SLND outside of clinical trials.
• Further research with robust study designs is needed to clarify the role of SLND in managing BCR.
