Summary

This summary is machine-generated.

Metastatic lymph nodes outside the extended pelvic lymph node dissection template correlate with advanced prostate cancer staging but not grading. Their impact on biochemical recurrence is inconclusive, suggesting further research is needed.

Area Of Science

  • Urology
  • Oncology
  • Pathology

Background

  • Prostate cancer (PCa) management relies on accurate staging, including lymph node (LN) assessment.
  • The extent of pelvic lymph node dissection (ePLND) impacts staging accuracy and oncological outcomes.
  • Evaluating LNs beyond the standard ePLND template is crucial for comprehensive risk stratification.

Purpose Of The Study

  • To assess the impact of metastatic LNs outside the ePLND template on prostate cancer staging, grading, and oncological outcomes.
  • To determine the association between LNs beyond the ePLND template and biochemical recurrence (BCR) after radical prostatectomy (RP).

Main Methods

  • Retrospective analysis of 860 prostate cancer patients undergoing radical prostatectomy (RP).
  • Detailed histopathological examination of specimens and collection of clinicopathological data.
  • Statistical analysis including Mann-Whitney U, Kruskal-Wallis, Kendall's tau-b, Kaplan-Meier, and Cox regression.

Main Results

  • Among 613 patients with modified-ePLND, 19.9% had pN1 disease, with 18% of these having metastatic LNs outside the ePLND template.
  • Patients with LNs beyond the ePLND template showed higher clinical T stages and more positive biopsy cores.
  • No significant correlation was found with Gleason Grading Group; BCR rates were not statistically different for pN1 vs. pN0 or for LNs outside the ePLND template.

Conclusions

  • Metastatic LNs outside the ePLND template are associated with more advanced prostate cancer staging.
  • These LNs do not correlate with tumor grading, and their impact on BCR is currently inconclusive.
  • Extended lymphadenectomy may improve staging but requires balancing against surgical morbidity.
