Abstract
The oncological and functional results of 329 cases in a population treated with extraperitoneal laparoscopic radical prostatectomy (ELRP) were evaluated retrospectively. A total of 329 inconsecutive patients with prostate cancer (PCa) who underwent ELRP were retrospectively analyzed. The median initial prostate-specific antigen (PSA) level was 17.35 ng/ml. The median biopsy Gleason score was 7.77. Patients with a T2 or T3a clinical stage had received preoperative neoadjuvant hormonal therapy (NHT) for 3 to 9 months prior to ELRP. No conversion or re-intervention were observed. The median time for anastomosis, surgery time and postoperative catheterization time were 13.0 min, 90.0 min and 6 days, respectively. The median estimated blood loss was 75 ml. There were 12 temporary urinary leakages requiring prolonged catheterization to 14 days. There was 1 case of deep vein thrombosis, 1 case of alimentary tract hemorrhage and 7 cases of anterior urethral stricture. The median follow-up time was 27 months. A total of 17 patients were lost during the follow-up period. No rectal injury, lymphocele, incision hernia, postoperative persistent urinary leak or anastomotic stricture occurred. Younger patients (≤67 years of age) had a more rapid recovery of continence and a better postoperative potency. The overall positive surgical margin rate was 16.7%, which correlated with the pathological stage and Gleason score, respectively (both P<0.001). A total of 89 (28.6%) patients were diagnosed with biochemical recurrence. The initial PSA value, PSM, pathological stage and Gleason score were identified as independent prognostic factors for biochemical recurrence-free survival using multivariate analysis. Our results demonstrated that preoperative NHT had significant effects on the pathological Gleason score (P<0.001) and surgical margin (P=0.027), but no significant impact on biochemical recurrence (P=0.202). The reproducibility of ELRP has been proven as a reliable curative treatment in Western countries during the last 15 years. Due to the increase in PCa patients, the results of our study may aid surgeons who use ELRP for the first time.
