Abstract:
Objective To study the short-term effectiveness of robotic-assisted laparoscopic radical prostatectomy in high-risk prostate cancer.Methods From March 2012 to March 2017,400 patients with high-risk prostate who underwent robotic-assisted laparoscopic radical prostatectomy were reviewed.The median age was 68 years old(ranged from 49 to 83 years),and the median PSA was 23.1 ng/ ml(ranged from 5.2 to 999.0 ng/ml).Preoperative parameters,surgical interventional data,postoperative pathology and follow-up data were collected.Logistic regression was used to analyze the risk factors of positive surgical margin in postoperative pathology.Results All the operations were successfully completed.Median operation time was 115 min(ranged 50-555 min),and median estimated blood loss was 110 ml(ranged 30-500 ml).Six patients had perioperative complications,among which two were rectal injury,two were cardio-cerebrovascular disease and two were hemorrhage.There was no perioperative death.Positive surgical margin was detected in 151 patients,accounting for 37.8％.A total of 345 cases (86.3％) underwent lymphadenectomy,of which 253 cases (63.3％) were performed standardized resection and 92 cases (23％) were performed extensive resection.The median number of resected lymph nodes was 9 (ranged 3-36).Eighty cases (23.2％,80/345) were positive in resected lymph nodes.Regression analysis showed that preoperative PSA ＞ 20 ng / ml or clinical stage ≥ T2c were risk factors for positive surgical margins.After a median follow-up of 14.4 months (ranged 2.0-58.8 months),the overall incidence of biochemical recurrence was 33.4％ (107/320),and the urinary continence rate one year after operation was 86.6％ (277/320).Conclusions Robotic-assisted laparoscopic radical prostatectomy in patients with high-risk prostate cancer was a feasible,safe and effective approach.Preoperative PSA and clinical stage were the risk factors for positive surgical margin.
