Summary
Laparoscopic extended pelvic lymph node dissection is a safe and effective procedure for high-risk prostate cancer patients. This minimally invasive technique offers results and morbidity comparable to open surgery.
Area of Science:
- Urology
- Surgical Oncology
Background:
- Controversy exists regarding the necessity of pelvic lymphadenectomy in prostate cancer patients undergoing radical prostatectomy.
- High-risk prostate cancer is defined by PSA > 10 ng/mL or Gleason score ≥ 7.
Purpose of the Study:
- To prospectively evaluate the outcomes and morbidity of laparoscopic extended pelvic lymph node dissection.
- To assess the safety and efficacy of this minimally invasive approach in high-risk prostate cancer.
Main Methods:
- 123 consecutive patients with high-risk prostate cancer underwent laparoscopic extended pelvic lymph node dissection prior to radical prostatectomy.
- Dissection boundaries were precisely defined, utilizing bipolar forceps and scissors for meticulous tissue coagulation.
- Mean PSA was 14.8 ng/mL, with an average of 21 lymph nodes removed per patient.
Main Results:
- Lymph node metastases were identified in 21 patients (17%).
- The overall complication rate was low, at 4%.
- The procedure demonstrated effective lymph node removal in high-risk cases.
Conclusions:
- Laparoscopic extended pelvic lymph node dissection is a safe and effective surgical option.
- Outcomes and morbidity are comparable to traditional open surgery.
- Offers the benefits of a minimally invasive technique for prostate cancer treatment.
