Abstract
To compare clinical outcomes between the use of robotic-assisted laparoscopic radical prostatectomy (RP) and radiotherapy (RT) with long-term androgen deprivation therapy (ADT) in locally advanced prostate cancer (PC), we enrolled 315 patients with locally advanced PC (clinical T-stage 3/4). Propensity score-matching at a 1:1 ratio was performed. The median follow-up period was 59.2 months (IQR: 39.8-87.4). There were 117 (37.1%) patients in the RP group and 198 (62.9%) patients in the RT group. RT patients were older and had higher PSA at diagnosis, higher Gleason score grade group and more advanced T-stage (all p<0.001). After propensity score-matching, there were 68 patients in each group. Among locally advanced PC patients, treatment with RP had a higher risk of biochemical recurrence compared to the RT group. In multivariate Cox regression analysis, treatment with RT plus ADT significantly decreased the risk of biochemical failure (HR: 0.162, p<0.001), but there was no significant difference in local recurrence, distant metastasis and overall survival (p=0.470, p=0.268 and p=0.509, respectively). This information may provide insight for clinicians and patients for decision-making regarding their preference for either treatment strategy.
