Abstract

Objectives: To determine if the number of lymph nodes (LNs) removed is an independent predictor of biochemical recurrence (BCR) in patients without LN metastases undergoing radical prostatectomy (RP). Material and methods: Retrospective analysis of 7,310 patients treated at 7 centers with RP and pelvic LN dissection for clinically localized prostate cancer between 2000 and 2011. Patients with LN metastases (n = 398) and other reasons (stated later in the article) (n = 372) were excluded, which left 6,540 patients for the final analyses. Results: Overall, median biopsy and RP Gleason score were both 7; median prostate specific antigen level was 6. ng/ml (interquartile range [IQR]: 5); and median number of LNs removed was 6 (IQR: 8). A total of 3,698 (57%), 2,064 (32%), and 508 (8%) patients had ≥6, ≥10, and ≥20 LNs removed, respectively. Patients with more LNs removed were older, had a higher prostate specific antigen level, had higher clinical and pathologic T stage, and had higher RP Gleason score (all P
