Purpose: The primary aim of the study was to assess the association between having a radiotherapy (RT) department on-site at the surgical centre and the performed postoperative treatment strategy for prostate cancer (PCa) patients. According to the current international guidelines, adjuvant radiotherapy (ART) or a regular prostate-specific antigen (PSA)-based follow-up with (early) salvage radiotherapy ((e)SRT) if needed is recommended in case of adverse pathological characteristics
Material and methods: Prospective data on consecutive robot-assisted radical prostatectomy (RARP) patients in Belgium from 2009 to 2016 were identified in the Belgian Robotic-Assisted-Laparoscopic-Prostatectomy (Be-RALP) database. Multivariable regression was used to evaluate patient- and facility-related factors associated with postoperative radiation treatment
Results: 2072 patients undergoing a RARP, suffering at least one of the following adverse pathological features, i.e., extracapsular extension (ECE), seminal vesicle invasion (SVI) or positive section margins (PSM), and with registered follow-up until 24 months were enrolled. After RARP, ART was applied to 9.1% and (e)SRT to 12.6% of the patients. Multivariable analysis demonstrated that patients were more likely to receive ART or (e)SRT if they were operated in a hospital with a RT department on-site (odds ratio, ART: 1.49 [1.07-2.07]; (e)SRT: 1.55 [1.16-2.06]). Furthermore, the presence of higher tumour category (T-category) and/or PSM on final pathology was associated with a higher chance of getting ART and (e)SRT (p < .01)
Conclusion: Variations in ART and (e)SRT are not only driven by patient-related characteristics. In our nationwide cohort, the availability of a RT department on-site at the surgical centre was found to be an independent predictor for ART and (e)SRT, with a 1.5 times higher odds of receiving postoperative RT during the first 24 months after surgery.
