Benefits and complications of laparoscopic pelvic lymphadenectomy for detection of stage D1 prostate cancer: a multicenter experience

Abstract

One hundred fifty-eight consecutive patients with clinically localized prostate cancer were submitted to staging laparoscopic pelvic lymphadenectomy (LPL) at 5 cooperative centers with one or more of the following conditions which were considered as risk factors for nodal disease: clinical stage C (or T3) disease, serum prostate-specific antigen > 20 ng/ml, Gleason sum > 6. The mean number of lymph nodes removed was 11 (range 2-29). Metastases from prostate cancer were found in 41 patients (25.9%). The proportion of lymph node-positive patients increases significantly with the presence of one, two or three of the conditions considered as risk factors (p < 0.00005). The benefit of LPL is limited to the lymph node-positive patients who can be spared a second operation.
