Abstract
OBJECTIVES To summarize the evidence regarding the treatment effect of adjuvant hormone therapy (AHT) in patients with prostate cancer (PCa). AHT following radiotherapy, chemotherapy, or surgery is widely used in patients with PCa. However, the treatment effect is inconsistent in individual trials. METHODS The electronic databases including PubMed, EmBase, and Cochrane Library were searched to identify randomized controlled trials (RCTs) in September 2016. RCTs that evaluated the effects of AHT in patients with PCa were included. Hazard ratio (HR) and relative risks (RR) were used to measure the treatment effects of AHT using a random effects model. The analyses were further stratified by factors that could affect the treatment efficacy. RESULTS A total of 14,594 potential studies were identified, and 27 RCTs were included. Compared with the control group, patients who received AHT were associated with a significant improvement in overall survival (OS) (HR: 0.78; 95% confidence interval [CI]: 0.71-0.85; P <.001), disease-free survival (DFS) (HR: 0.50; 95% CI: 0.39-0.65; P <.001), total mortality (RR: 0.90; 95% CI: 0.85-0.96; P = .001), recurrence (RR: 0.70; 95% CI: 0.60-0.81; P <.001), and disease-specific mortality (RR: 0.70; 95% CI: 0.56-0.87; P <.001). However, no significant difference was observed between AHT and control for response rate (RR: 1.75; 95% CI: 0.91-3.37; P = .095). CONCLUSIONS The findings of this meta-analysis confirmed that patients who received AHT had a significant improvement in OS, DFS, total mortality, recurrence, and disease-specific mortality. Further, large-scale RCTs are required to evaluate the treatment effect in specific subpopulations.

Abstract
OBJECTIVES To describe the established therapies for localised prostate cancer (PC) in Spain and to assess compliance with the 2010 UAE guidelines. PATIENTS AND METHODS This was an epidemiological, observational, prospective and multicentre study. Of the 3,918 patients diagnosed with PC during 2010, only those patients with localised PC were included. Follow-up was ultimately conducted for a minimum of one year from the diagnosis for 3,713 patients (94.77%). The treatment groups assessed were as follows: radical prostatectomy, radiation therapy, hormone therapy, brachytherapy, active surveillance or observation and experimental local treatment (cryotherapy or other treatment). Compliance with the recommendations of the EAU guidelines was studied, describing the treatment groups according to D'Amico risk stratification criteria (localised [low, intermediate and high risk] and locally advanced), age, PSA and Gleason score. RESULTS By applying the D'Amico criteria, we included 3,641 (92.93%) patients. Based on the UAE recommendations: 1) 68.87% of the patients at low-intermediate risk aged≤65 years underwent radical prostatectomy; 2) 34.51% of the patients>65 years at high risk with locally advanced disease were administered radiation therapy and hormone therapy; 3) 30.36% of the patients at high risk with locally advanced disease were only treated with hormone therapy; 4) 15.20% of the patients at low risk were only treated with brachytherapy; 5) active surveillance or observation was selected for 2.44% of the patients aged≤65 years and for 10.63% of the patients at low-intermediate risk who were>65 years. Lastly, 86.5% of the patients at low risk underwent a single treatment, and 43.62% of the patients at high risk with locally advanced disease underwent combined treatments. CONCLUSIONS This is the first national European study to evaluate the therapeutic management of localised PC based on the risk group to which the patient belonged. Most young patients (≤65 years) with low-intermediate risk localised PC were treated with surgery, which adheres to the recommendations of the 2010 UAE guidelines. Various therapeutic combinations have been employed for patients with high-risk, locally advanced localised tumours, revealing the need for a multidisciplinary approach (Controlled-trials.com number: ISRCTN19893319).

Abstract
Radiation therapy (RT) is one of the mainstay treatments for prostate cancer (PCa). The potentially curative approaches can provide satisfactory results for many patients with non-metastatic PCa; however, a considerable number of individuals may present disease recurrence and die from the disease. Exploiting the rich molecular biology of PCa will provide insights into how the most resistant tumor cells can be eradicated to improve treatment outcomes. Important for this biology-driven individualized treatment is a robust selection procedure. The development of predictive biomarkers for RT efficacy is therefore of utmost importance for a clinically exploitable strategy to achieve tumor-specific radiosensitization. This review highlights the current status and possible opportunities in the modulation of four key processes to enhance radiation response in PCa by targeting the: (1) androgen signaling pathway; (2) hypoxic tumor cells and regions; (3) DNA damage response (DDR) pathway; and (4) abnormal extra-/intracell signaling pathways. In addition, we discuss how and which patients should be selected for biomarker-based clinical trials exploiting and validating these targeted treatment strategies with precision RT to improve cure rates in non-indolent, localized PCa.

Abstract
OBJECTIVE To study the expression of TRPC6 among prostate cancer cells, establish high expression cell lines of TRPC6, and to provide potential cell mode for prostate cancer oncogenesis and development. METHODS Occurrence and development of prostate cancer cells, PC3, PC-3 m DU145, 22 rv1, LNCaP and normal prostate epithelial cells in the PrEC TRPC6 expression level were detected by QPCR method. Calcium phosphate transfection method was used to package retrovirus pLEGFP-N1-TRPC6 and pLEGFP-N1-vector and infect the prostate cancer cells, a stable high expression of TRPC6 prostate cancer cells. Sable cell lines of TRPC6, matrix metalloproteinase (MMP) 2, MMP9 expression was detected by QPCR and Western blot. Change of cell invasion ability was detected by Transwell. RESULTS The expression level of prostate cancer cells TRPC6 were higher than control group PrEC cells. Among TPRC6 the expression of cell line PC 3 transfer potential wre the lowest, and high transfer cell line PC-3M express was the highest. Real-time fluorescent quantitative PCR and western blot results showed that after filter, the seventh generation of cell TRPC6 protein and mRNA expression levels were higher than the control group obviously. Transwell experimental results showed that the overexpression of TRPC6 could promote the invasion ability of PC3 prostate cancer cells. CONCLUSIONS TRPC6 expressed in prostate cancer cells is in disorder, and its action may be associated with the invasion and metastasis of prostate cancer cells; successful establishment of stable high expression of TRPC6 prostate cancer cells primarily confirm the invasion-trigger ability of TRPC6 on prostate cancer, and lay down the Foundation for exploring the TRPC6's role in the occurrence and development of prostate cancer mechanism.

KDM5C is overexpressed in prostate cancer and is a prognostic marker for prostate-specific antigen-relapse following radical prostatectomy. THE AMERICAN JOURNAL OF PATHOLOGY 2014; 184:2430-7.

Abstract
Currently, few prognostic factors are available to predict the emergence of castration-resistant prostate cancer and no curative options are available. Epigenetic gene regulation has been shown to trigger prostate cancer metastasis and androgen independence. Histone lysine demethylases (KDMs) are epigenetic enzymes that can remove both repressive and activating histone marks. KDM5 family members are capable of removing the histone H3 lysine 4 dimethylation-activating mark, rendering them potential players in the down-regulation of tumor suppressors and suggesting that their activity could repress oncogenes. Here, we systematically investigated KDM5C expression patterns in two independent radical prostatectomy cohorts (822 prostate tumors in total) by immunohistochemistry. Positive nuclear KDM5C staining was significantly associated with a reduced prostate-specific antigen relapse-free survival. Our study confirmed that nuclear KDM5C expression is an independent prognostic parameter. Most strikingly, the prognostic value of nuclear KDM5C expression for progression-free survival was exclusively pronounced for the Gleason group 7. In addition, KDM5C knockdown resulted in growth retardation of prostate cancer cells in vitro and induced regulation of several proliferation-associated genes. Our data indicate that KDM5C is functionally involved in proliferation control of prostate cancer cells and might represent a novel attractive therapy target. Moreover, overexpression of KDM5C is an independent new predictive marker for therapy failure as determined by biochemical recurrence in patients after prostatectomy.

Abstract
Early prostate cancer (PCa) is generally treatable and associated with good prognosis. After a variable time, PCa evolves into a highly metastatic and treatment-refractory disease: castration-resistant PCa (CRPC). Currently, few prognostic factors are available to predict the emergence of CRPC, and no curative option is available. Epigenetic gene regulation has been shown to trigger PCa metastasis and androgen-independence. Most epigenetic studies have focused on DNA and histone methyltransferases. While DNA methylation leads to gene silencing, histone methylation can trigger gene activation or inactivation, depending on the target amino acid residues and the extent of methylation (me1, me2, or me3). Interestingly, some histone modifiers are essential for PCa tumor-initiating cell (TIC) self-renewal. TICs are considered the seeds responsible for metastatic spreading and androgen-independence. Histone Lysine Demethylases (KDMs) are a novel class of epigenetic enzymes which can remove both repressive and activating histone marks. KDMs are currently grouped into 7 major classes, each one targeting a specific methylation site. Since their discovery, KDM expression has been found to be deregulated in several neoplasms. In PCa, KDMs may act as either tumor suppressors or oncogenes, depending on their gene regulatory function. For example, KDM1A and KDM4C are essential for PCa androgen-dependent proliferation, while PHF8 is involved in PCa migration and invasion. Interestingly, the possibility of pharmacologically targeting KDMs has been demonstrated. In the present paper, we summarize the emerging role of KDMs in regulating the metastatic potential and androgen-dependence of PCa. In addition, we speculate on the possible interaction between KDMs and other epigenetic effectors relevant for PCa TICs. Finally, we explore the role of KDMs as novel prognostic factors and therapeutic targets. We believe that studies on histone demethylation may add a novel perspective in our efforts to prevent and cure advanced PCa.
