Aim: Metastatic prostate cancer (mPCa) has a poor outcome with median survival of two to five years. The use of androgen deprivation therapy (ADT) is a gold standard in management of this stage.  Aim of this study is to analyze the prognostic value of PSA kinetics of patient treated with hormonal therapy related to survival from several published studies Method: Systematic review and meta-analysis was performed using literature searching in the electronic databases of MEDLINE, Science Direct, and Cochrane Library. Inclusion criteria were mPCa receiving ADT, a study analyzing Progression Free Survival (PFS), Overall Survival (OS), or Cancer Specific Survival (CSS) and prognostic factor of survival related to PSA kinetics (initial PSA, PSA nadir, and time to achieve nadir (TTN)). The exclusion criteria were metastatic castration resistant of prostate cancer (mCRPC) and non-metastatic disease. Generic inverse variance method was used to combine hazard ratio (HR) within the studies. Meta-analysis was performed using Review Manager 5.2 and a p-value <0.05 was considered statistically significant. Results: We found 873 citations throughout database searching with 17 studies were consistent with inclusion criteria. However, just 10 studies were analyzed in the quantitative analysis. Most of the studies had a good methodological quality based on Ottawa Scale. No significant association between initial PSA and PFS. In addition, there was no association between initial PSA and CSS/ OS. We found association of reduced PFS (HR 2.22; 95% CI 1.82 to 2.70) and OS/ CSS (HR 3.31; 95% CI 2.01-5.43) of patient with high PSA nadir. Shorter TTN was correlated with poor result of survival either PFS (HR 2.41; 95% CI 1.19 – 4.86) or CSS/ OS (HR 1.80; 95%CI  1.42 – 2.30) Conclusion: Initial PSA before starting ADT do not associated with survival in mPCa.  There is association of PSA nadir and TTN with survival

Background. The present study aimed to analyse factors influencing the effects of androgen deprivation therapy (ADT) in patients with newly diagnosed metastatic castration-naïve prostate cancer (mCNPC), especially in low-volume disease (LVD), according to subclassification of metastatic prostate cancer established by the CHAARTED trial. Materials and Methods. We reviewed 648 patients with newly diagnosed mCNPC receiving ADT at Chang Gung Memorial Hospital from January 2007 to December 2016. Basic characteristics and PSA kinetics profile were subsequently evaluated. Results. 48.3% of LVD patients progressed to castration-resistant prostate cancer (mCRPC). Among them, CRPC group had significantly shorter time to PSA nadir (TTN) and faster time from PSA nadir to CRPC (TFNTC) ( p  < 0.001) compared to non-CRPC group. PSA doubling time (PSADT) < 4 months tended to be associated with faster disease progression and shorter overall survival (OS). Among all patients with metastatic prostate cancer, those with shorter TTN <9 months, higher nadir PSA level ≥1 ng/mL, and shorter PSADT <3 months had increased tendency for biochemical progression. Conclusions. PSADT is an effective clinical predictor for disease progression and survival in LVD. Other PSA kinetics including TTN and TFNTC, though not the major predictors for disease progression or OS in LVD, might be the predictors for disease control status.

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.

188 Background: Androgen-deprivation therapy (ADT) is the standard of treatment for patients with newly diagnosed metastatic prostatic cancer. Nevertheless, recent trials have suggested a role for chemotherapy in these patients. We performed a systematic review and meta-analysis to assess the efficacy and safety of docetaxel-based chemotherapy in combination with ADT for patients with hormone-sensitive metastatic prostate cancer. Methods: Randomized clinical trials (RCT) were identified after systematic searching of electronic databases (MEDLINE, OVID and The Cochrane Central Register of Controlled Trials), as well as ASCO conference proceedings from 2010 to 2015. We included only RCT comparing ADT versus the combination of ADT plus docetaxel-based chemotherapy in patients with newly diagnosed metastatic prostate cancer. A random-effect model was used to determine the pooled hazard ratio (HR) for the efficacy outcomes: overall survival (OS) and clinical progression-free survival (PFS), according to the inverse-variance method. Heterogeneity was measured using the Q and I2statistics. Results: Three RCT (n = 2 262), were included in our meta-analysis (E3805, GETUG-AFU 15 and the M1 subgroup from STAMPEDE Trial). Docetaxel-based chemotherapy plus ADT was associated with improved OS (HR: 0.74; 95% CI: 0.60-0.90; p = 0.003). The heterogeneity of these trials was moderate (Tau2: 0.02; I2: 51%; p = 0.13). Clinical PFS was also significantly better in patients receiving docetaxel-based chemotherapy (HR: 0.67; 95% CI 0.55-0.82; p = 0.0001), with moderate between-study heterogeneity detected (Tau2: 0.01; I2: 42%; p = 0.19). Different subset of patients in these trials can explain the aforementioned heterogeneity. Regarding adverse drug reactions grade 3 or higher, neutropenia was reported in a range from 36% in the GETUG-AFU 15 Trial to 12% in the STAMPEDE trial and febrile neutropenia was reported from 6.1% in the E3805 Trial to 12% in the STAMPEDE Trial. Conclusions: The addition of docetaxel-based chemotherapy to ADT improves OS and clinical PFS. New trials are needed to determine which patients benefit the most from this intervention.
