Summary

Sentinel pelvic lymph node dissection (PLND) accurately stages prostate cancer by identifying the first lymph nodes. This minimally invasive technique can potentially replace extended PLND, reducing surgical extent without compromising accuracy.

Area of Science:

  • Urology
  • Surgical Oncology
  • Nuclear Medicine

Background:

  • Accurate lymph node staging is critical for prostate cancer management.
  • Current imaging techniques cannot detect small metastases in lymph nodes.
  • Pelvic lymph node dissection (PLND) is the standard for staging clinically localized prostate cancer.

Purpose of the Study:

  • To evaluate the feasibility and accuracy of laparoscopic sentinel pelvic lymph node dissection (SLND) preceding radical prostatectomy.
  • To determine if SLND can be an alternative to extended PLND.

Main Methods:

  • Laparoscopic sentinel PLND was performed in 140 patients with clinically localized prostate cancer.
  • Radioguided surgery utilized a radiopharmaceutical injected into the prostate to identify sentinel lymph nodes (SLNs).

Single-port Non-liposuction Endoscopic Axillary Lymph Node Dissection in Breast Cancer Surgery

Published on: April 3, 2026

  • Preoperative scintigraphy and intraoperative detection of SLNs were analyzed.

    • Main Results:

    • At least one SLN was detected in 95.3% of patients.
    • Intraoperative SLN detection correlated with preoperative scans in 70.7% of cases.
    • Laparoscopic SLND demonstrated potential to reduce the extent of PLND without compromising diagnostic accuracy.

    Conclusions:

    • Sentinel PLND is a reliable method for staging prostate cancer.
    • Laparoscopic SLND can be performed effectively before radical prostatectomy.
    • This technique offers a promising alternative to extended PLND, potentially reducing surgical morbidity.
