Should laparoscopy be the standard approach used for pelvic lymph node dissection?
Involvement of the pelvic lymph nodes in patients with prostate cancer worsens the overall prognosis of this common disease entity. Prior radiographic staging techniques, including fine-needle aspiration, are limited by a poor sensitivity and are not reliable. The gold standard for the evaluation of pelvic lymph nodes in men with prostate cancer involves performing a lymphadenectomy. Historically, this procedure was performed using an open surgical technique. Unfortunately, this invasive procedure is associated with significant morbidity. In response, modern surgical technology has provided newer, less invasive techniques, including laparoscopic pelvic lymphadenectomy (LPLND). Improved detection of localized prostate cancer through the institution of screening protocols and early detection programs has decreased the number of patients presenting with lymph node involvement. Various clinical indicators, including prostate-specific antigen, grade, and stage, have been used to improve the selection of "high-risk" patients that are appropriate candidates for pelvic lymph node dissection. The technique of LPLND is a valid option in the armamentarium for staging of prostate cancer. The laparoscopic approach provides the same staging accuracy as the open surgical technique and is superior with respect to morbidity. LPLND is limited to patients who present with a high risk of advanced prostate cancer. In addition, the urologist must accept the additional training, financial expense, and "learning curve" associated with this technique.
