Summary

Laparoscopic lymph node sampling is a safe procedure for staging locally advanced prostate cancer. This technique helps identify patients who will not benefit from radical radiotherapy, improving treatment decisions.

Area of Science:

  • Urology
  • Surgical Oncology
  • Oncology

Background:

  • Locally advanced prostate cancer requires accurate staging to guide treatment.
  • Identifying lymph node metastases is crucial for treatment planning, particularly before radical radiotherapy.
  • Current methods may not reliably identify all patients with metastatic disease.

Purpose of the Study:

  • To evaluate the safety and role of laparoscopic lymph node sampling in patients with locally advanced prostate cancer.
  • To determine if laparoscopic lymphadenectomy can be safely performed by experienced urologists.
  • To assess the efficacy of preoperative criteria in selecting patients for lymph node sampling.

Main Methods:

  • Prospective study of 50 patients with locally advanced prostate cancer and >20% risk of lymph node metastases.

  • Laparoscopic pelvic lymphadenectomy performed by trained urologists.
  • Data collected included patient demographics, preoperative risk factors (PSA, clinical stage, Gleason grade), operative details, and complications.

    • Main Results:

    • 24% of patients had lymph node metastases.
    • No significant differences in PSA, Gleason grade, or clinical stage between node-positive and node-negative groups.
    • Mean operative time was 110 minutes, with a learning curve observed.
    • Low complication rates: 5% major and 17% minor.

    Conclusions:

    • Laparoscopic lymph node sampling is a safe and feasible procedure for staging prostate cancer.
    • Preoperative selection criteria (PSA, stage, Gleason grade) can identify at-risk patients.
    • This procedure is essential for selecting patients who may not benefit from radical conformal radiotherapy.
