End Point

Context: Several studies reported the application of androgen deprivation therapy and radiotherapy in patients with biochemical recurrence after prostate cancer operation. Objective: To perform a systematic review and meta-analysis evaluating of endocrine therapy and radiotherapy in patients with biochemical recurrence after prostate cancer surgery. The primary end point was biochemical progression-free survival (bPFS). Secondary end point was overall survival (OS). Methods: A systematic review of PubMed/Medline, Embase, and Cochrane databases to identify relevant studies published in English up to March 2020. Twelve studies were selected for inclusion. Results: There were 11 studies included in the present study. Including two randomized controlled trials and nine cohort studies. The meta-analysis shows a significant bPFS benefit from androgen deprivation therapy and radiotherapy in patients with biochemical recurrence after prostate cancer operation. (hazard ratio [HR]: 0.57; 95% confidence interval CI, 0.52–0.63; p < .001). For patients with GS < 7 and low-risk patients, combined treatment can have a benefit for BPFs (HR: 0.53; 95% CI, 0.37–0.76; HR: 0.58; 95% CI, 0.36–0.93). Androgen deprivation therapy and radiotherapy in patients with biochemical recurrence was associated with a slightly OS improvement (HR: 0.73; 95% CI, 0.57–0.93; p = 0.01). Conclusions: Compared with salvage radiotherapy alone, This meta-analysis shows a significant bPFS benefit from endocrine therapy combined with salvage radiotherapy in patients with biochemical recurrence after prostate cancer operation. And benefit more for high-risk groups. However, there was no significant benefit in group GS ≥ 8. It shows a slightly OS benefit from endocrine therapy combined with salvage radiotherapy in patients with biochemical recurrence.

65 Background: To date there is no robust evidence comparing the outcomes of robotic and open radical prostatectomies in patients with high-risk prostate cancer. The purpose of this study is to perform a meta-analysis comparing the rates of positive surgical margins (PSM) and biochemical recurrence (BCR) between open radical prostatectomy (ORP) and robot-assisted radical prostatectomy (RARP) in patients with high-risk prostate cancer. Methods: A systematic review was performed on Pubmed, Embase and Scopus databases in August 2016, according to the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement. References retrieved were evaluated using the Newcastle-Ottawa scale and the Black and Down’s tool for quality assessment. Nine retrospective cohorts comparing ORP and RARP were selected and included in the meta-analysis. Results: Nine studies reported the PSMs. Patients treated with RARP presented less risk of PSMs (risk difference -0.04, p 0.02) than those treated with ORP. Five articles reported hazard ratios for BCR-free survival. Patients treated with RARP had less risk of BCR (HR 0.72, 95% CI 0.58-0.89) than those treated with ORP. Reports for PSM assessment were considered of adequate quality, while the studies retrieved for BCR assessment were considered limited because of the heterogeneity of their results. Conclusions: Patients with high-risk prostate cancer treated with RARP have less risk of having PSM and BCR when compared to those treated with ORP. A strong conclusion is precluded due to the observational nature of the studies retrieved for our analysis.

Abstract Background The appropriate timing of radiotherapy (RT) for patients after radical prostatectomy (RP) with adverse pathological features (APFs) remains controversial. This systematic review was conducted to compare the efficacy of adjuvant radiotherapy (ART) and salvage radiotherapy (SRT). Methods PubMed, EMBASE, Web of Science and the Cochrane Library electronic databases were searched to retrieve the required. The hazard ratio (HR) and corresponding 95% confidence interval (CI) of overall survival (OS), biochemical recurrence-free survival (BRFS) and distant metastases-free survival (DMFS) were extracted. The survival benefits of ART with SRT (including early salvage radiotherapy (ESRT)) were analyzed. The process of the meta-analysis was performed with RevMan version 5.3. Results A total of fifteen retrospective studies were finally included in the final analysis including 5586 patients. The pooled analysis indicated that ART could achieve better control of prostate cancer and improve OS (p = 0.0006), BRFS (p < 0.0001) and DMFS (p < 0.0001), when compared to SRT. The subgroup analysis of the 5-year OS rate demonstrated that the ART group still had survival advantages compared to the SRT group (p = 0.0006). However, ART and SRT were comparable in 10-year OS rate (p = 0.07). ART had advantages over SRT in both 5-year (p = 0.0003) and 10-year BRFS (p = 0.0003). The subgroup analysis with different follow-up starting points from RP or RT was essentially consistent with the above results. The pooled analysis also showed that ART was superior to ESRT on OS (p = 0.008) and DMFS (p = 0.03), and comparable to ESRT on BRFS (p = 0.1). Conclusions According to this meta-analysis, ART could be served as a preferential treatment for patients with APFs after RP to improve prognosis. Certainly, high-quality, multicenter randomized controlled trials (RCTs) are expecting to confirm the outcomes of our meta-analysis in the future.
