INTRODUCTION: The aim of this study was to investigate if neoadjuvant hormone therapy (NHT) is associated with surgical outcomes of laparoscopic radical prostatectomy.

METHODS: A total of 286 patients with organ-confined prostate cancer and a preoperative prostate volume that could be estimated by transrectal ultrasound underwent laparoscopic radical prostatectomy between 2006 and 2011 at our institution. We examined whether NHT was associated with pneumoperitoneum time (PT) or estimated blood loss during laparoscopic radical prostatectomy.

RESULTS: NHT was performed in 80 patients; the mean duration of NHT was 5.2 ± 0.2 months. Multivariate analysis demonstrated that history of NHT and no NHT were not independent predictors of prolonged PT or higher estimated blood loss. Next, we evaluated 57 patients whose estimated preoperative baseline prostate volume was over 50 mL. Multivariate analysis demonstrated that no history of NHT (P = 0.011) was an independent predictor of prolonged PT. PT was significantly shorter in the NHT group (164.5 ± 39.0 min, n = 26) than in the non-NHT group (184.0 ± 36.7 min, n = 31) (P = 0.048). In the NHT group, mean prostate volume was reduced from 63.7 ± 16.0 mL to 42.1 ± 18.6 mL (33.9% reduction) by NHT.

CONCLUSION: NHT shortened the PT of the patients whose preoperative baseline prostate volume was over 50 mL. This suggests NHT downsized prostate volume, resulting in greater working space and shorter PT.
