Abstract

Objective: Controversy persists concerning the role of pelvic lymph node dissection (PLND) in patients with preoperative PSA values <10ng/ml undergoing treatment for prostate cancer with a curative intent. The aim of this study was to determine the incidence of lymph node metastasis in this subgroup of patients.

Methods: Patients with clinically localized prostate cancer and a serum PSA<10ng/ml, without neoadjuvant hormonal or radiotherapy, with negative staging examinations who underwent radical retropubic prostatectomy with bilateral extended PLND and with >/=10 lymph nodes detected by the pathologist in the surgical specimen, were included in the study.

Results: A total of 231 patients with a median serum PSA of 6.7ng/ml (range 0.4-9.98) and a median age of 62 years (range 44-76) were evaluated. A median of 20 (range 10-72) nodes were removed per patient. Positive nodes were found in 26 of 231 patients (11%), the majority of which (81%) had a Gleason score >/=7 in the surgical specimen. Of the patients with a Gleason score >/=7 in the prostatectomy specimen 25% had positive nodes, whereas only 3% with a Gleason score </=6 were node positive.

Conclusions: The incidence of positive nodes in patients with clinically localized prostate cancer, a serum PSA<10ng/ml and a Gleason score >/=7 in the prostatectomy specimen was 25% after extended PLND. It seems that in this patient group extended PLND, including removal of nodes along the internal iliac vessels, is warranted.
