Purpose: To report early operative outcomes and asses continence in 100 consecutive patients who underwent Retzius-sparing robotic-assisted laparoscopic radical prostatectomy Materials and Methods: This was a prospective, single-center, consecutive case series of 100 and 100 patients undergoing a Retzius-sparing and a conventional robotic-assisted laparoscopic radical prostatectomy, respectively, by a single surgeon between March 2015 and April 2017. Results: Baseline patient characteristics were similar between the two groups. The Retzius-sparing approach required significantly less console time (120.0 vs. 144.0 mins, p<0.001). There were no differences in intra- or post-operative complication rates and hospital length of stay was similar in the two groups. Incidence of positive surgical margins was non-significantly different between the two groups, with 17% and 13% of pT2 patients and 49% and 48% of pT3 patients in the Retzius-sparing and conventional groups, respectively. Patients in the Retzius-sparing group had significantly superior rates of achieving post-operative urinary continence (log-rank test: p<0.001), with 20% of patients continent within the first month, compared to 8% of patients in the conventional group. Mean number of pads per day needed at three, six, nine, and 12 months post-operatively was also significantly lower in the Retzius-sparing group. Conclusions: Retzius-sparing robotic-assisted laparoscopic radical prostatectomy requires shorter console time, is oncologically safe, and leads to significantly superior continence outcomes compared to conventional robotic-assisted laparoscopic radical prostatectomy.
Purpose: Early treatment intensification with neoadjuvant therapy may improve outcomes in patients with high-risk, localized prostate cancer treated with radical prostatectomy. Our objective was to compare pathologic, oncologic, and safety outcomes of neoadjuvant abiraterone acetate plus leuprolide acetate with or without cabazitaxel prior to radical prostatectomy in patients with localized, high-risk prostate cancer. Patients and Methods: This open-label, multicenter, phase II trial randomized men with clinically localized, D'Amico high-risk prostate cancer to neoadjuvant abiraterone acetate (1,000 mg/day) and leuprolide acetate (22.5 mg every 3 months) with or without cabazitaxel (25 mg/m2) prior to radical prostatectomy. The primary outcome was pathologic complete response (pCR) or minimal residual disease (MRD). Secondary outcomes included surgical margins, lymph node involvement, pathologic stage, 12-month biochemical relapse-free survival (BRFS) rates, and safety profile. Results: The per-protocol population consisted of 70 patients [cabazitaxel arm (Arm A): 37, no cabazitaxel arm (Arm B): 33]. Median patient age and prostate-specific antigen levels were 63.5 years [interquartile range (IQR), 58.0–68.0] and 21.9 ng/mL (IQR, 14.6–42.8), respectively. pCR/MRD occurred in 16 (43.2%) versus 15 patients (45.5%) in arms A and B, respectively (P = 0.85). pCR occurred in two (5.4%) versus three patients (9.1%) in arms A and B, respectively (P = 0.66). Patients with ≤ 25% total biopsy cores positive had increased odds of pCR/MRD (P = 0.04). Patients with pCR/MRD had superior 12-month BRFS rates (96.0% vs. 62.0%, P = 0.03). Grade 3+ adverse events occurred in 42.5% and 23.7% of patients in arms A and B, respectively (P = 0.078). Conclusions: Neoadjuvant cabazitaxel addition to abiraterone acetate/leuprolide acetate prior to radical prostatectomy did not improve pCR/MRD in clinically localized, high-risk prostate cancer.
