Long-term Oncologic Outcomes of Robotic-assisted Radical Prostatectomy by a Single Surgeon.
2017
The aim of the study was to evaluate the long-term oncology outcomes of prostate cancer patients receiving robotic-assisted radical prostatectomy (RARP).We retrospectively evaluated 111 patients with clinically-localized prostate cancer receiving RARP with a mean follow-up of 103.43 months.The 5-year BCRFS and 8-year BCRFS among low-, intermediate-, and high-risk patients were 95.5% vs. 77.1% vs. 53.7% and 95.5% vs. 61.2% vs. 48.1% (p=0.000). The median time to BCR in these three groups was 122.5, 98.0, and 79.2 months. Regarding postoperative factors, positive lymph node (HR=3.748, 95% CI=1.407-9.984), pathology Gleason score (HR=1.507, 95%CI=1.010-2.248), and postoperative nadir PSA <0.003 ng/ml (HR=0.058, 95%CI=0.020-0.166) were independent risk factors for BCR.D'Amico risk classification was effective at predicting biochemical recurrence in patients receiving RARP. Furthermore, postoperative risk factors such as metastatic lymph node, pathology Gleason score, and nadir PSA <0.003 ng/ml were independent predictors of biochemical recurrence.
