Abstract
Low testosterone (T), common in aging men, associates with cardiovascular disease. We investigated whether follicle-stimulating hormone (FSH), which is affected by T, modulates the cardiovascular effects associated with low T or castration. FSHβ-/-:low-density lipoprotein receptor (LDLR)-/- mice, untreated or castrated (orchiectomy, gonadotropin-releasing hormone agonist or antagonist), demonstrated significantly less atherogenesis compared with similarly treated LDLR-/- mice, but not following FSH delivery. Smaller plaque burden in LDLR-/- mice receiving gonadotropin-releasing hormone antagonists vs agonists were nullified in FSHβ-/-:LDLR-/- mice. Atherosclerotic and necrotic plaque size and macrophage infiltration correlated with serum FSH/T. In patients with prostate cancer, FSH/T following androgen-deprivation therapy initiation predicted cardiovascular events. FSH facilitates cardiovascular disease when T is low or eliminated.

Abstract
BACKGROUND Hormone therapy, which is widely prescribed for prostate cancer, might induce cognitive impairment and affect the autonomy of elderly patients. However, previous studies provided conflicting results. The aim of this systematic review and meta-analysis was to synthesize the longitudinal impact of hormone therapy on objective (cognitive tests) and subjective (questionnaires) cognition. METHODS A search was performed of the PubMed, Web of Science, and PsycINFO databases. Studies that longitudinally assessed cognition in patients undergoing androgen-deprivation therapy and new-generation hormone therapy were considered. To perform a meta-analysis, available scores were aggregated and classified into six objective domains and one subjective domain. Weighted mean effect sizes were computed using a random effect model. RESULTS Twenty studies were included in the systematic review (1440 patients), and 15 could be included in the meta-analysis (1093 patients). In the systematic review, 20%-50% of patients had objective cognitive impairment before treatment initiation. The meta-analysis revealed a decline in subjective cognition (g = -0.44; p = .03) with androgen-deprivation therapy and new-generation hormone therapy. All other effect sizes were small (from g = -0.02 to g = 0.18), and none of them indicated a significant decline in objective cognition. Significant heterogeneity was observed in all domains of objective cognition. CONCLUSIONS This synthesis presents the first meta-analytic evidence of the negative impact of androgen-deprivation therapy and new-generation hormone therapy on subjective cognition. In contrast, there was no conclusive evidence of a decline in objective cognition. The high heterogeneity underscores the need for homogeneous cognitive research on prostate cancer. PLAIN LANGUAGE SUMMARY There is no consensus on the cognitive impairment induced by hormone therapy for prostate cancer, despite the implications for patients' care and daily life. This synthesis of published studies demonstrated an increase in perceived cognitive difficulties but did not prove a decline in cognitive performance during treatment.

Abstract
BACKGROUND New-generation imaging techniques and the increasing use of surgery in high-risk prostate cancer (PCa) allow us to detect many cases of nodal disease at initial diagnosis or after resection. The treatment of PCa with pathologic regional nodes has evolved from the exclusive use of systemic therapy to its combination with locoregional treatment. It can also represent a benefit in the overall survival. However, the evidence from randomised studies is limited. Thus, we review the most relevant results in this scenario. MATERIALS AND METHODS A literature search was conducted in MEDLINE, PubMed, EMBASE, Clinical-Trials.gov and Web of Science on January 2023 to review node-positive PCa by considering the relevant literature on this topic published with no restrictions on date and language. The search keywords used were "Prostatic Neoplasms" (MeSh) and "Node-positive" (Text Word) and "Radiotherapy" (MeSh) and ("Androgen Antagonists" (MeSh) or "Antineoplastic Agents, Hormonal" (MeSh)), which are indexed within the Medical Subject Headings database. RESULTS The management of node-positive PCa has no clear definitive consensus at the initial disease diagnosis or after surgery. However, in this review, we summarise the existing literature for the management of these patients in both scenarios, considering imaging tests, radiotherapy, hormone therapy and second-generation hormonal treatments. CONCLUSIONS The combination of radiotherapy and androgen-deprivation therapy is the treatment of choice. The addition of second-generation hormone therapy, plus the intensification of radiotherapy schedules, will likely change the treatment paradigm for these patients.

Abstract
BACKGROUND/AIM No practical biomarkers predict the response to enzalutamide in chemotherapy-naïve metastatic castration-resistant prostate cancer (mCRPC). The present study aimed to evaluate the prognostic value of the initial-to-nadir prostate-specific antigen (PSA) ratio (I/N PSA) in primary hormone therapy for metastatic hormone-naïve prostate cancer associated with the response to first-line enzalutamide in mCRPC. PATIENTS AND METHODS Twenty-eight patients with mCRPC received first-line enzalutamide to determine the associations between I/N PSA in combined androgen blockade and clinical outcomes. The PSA response was defined as ≥90% decline from baseline in patients with mCRPC. RESULTS The optimal cutoff I/N PSA value for PSA response was 1,219 (sensitivity=71.4%, specificity=92.9%, area under the receiver operating characteristic curve=0.85). The PSA response was 90.9% in the high I/N PSA group and 23.5% in the low I/N PSA group. The median overall survival, prostate cancer-specific survival, and radiographic progression-free survival after initiation of enzalutamide were statistically greater for the high I/N PSA group than the low group. Multivariable analysis showed that I/N PSA was an independent predictor of overall survival (hazard ratio=0.23; p=0.026). CONCLUSION In chemotherapy-naïve patients with mCRPC, I/N PSA was a predictive and prognostic biomarker for first-line enzalutamide. The I/N PSA can enable optimization of individual treatment in real-world clinical practice.

Abstract
Abiraterone, an androgen biosynthesis inhibitor drug approved by the Food and Drug Administration (FDA) in 2011 for the treatment of metastatic prostate cancer, has seen an increase in prescriptions over the years, owing largely to the aging population and the association of prostate cancer with increasing age. As the rate of abiraterone prescription increases, it is important for physicians to be aware of its adverse effects profile to improve patient outcomes. This case report explains the mechanism, clinical presentation, and management of abiraterone-induced hypokalemia in a 67-year-old male with prostate cancer and highlights the importance of close monitoring and management of electrolyte levels for patients on abiraterone.

Abstract
BACKGROUND Controlling the asymmetric distribution of phospholipids across biological membranes plays a pivotal role in the life cycle of cells; one of the most important contributors that maintain this lipid asymmetry are phospholipid-transporting adenosine triphosphatases (ATPases). Although sufficient information regarding their association with cancer exists, there is limited evidence linking the genetic variants of phospholipid-transporting ATPase family genes to prostate cancer in humans. METHODS In this study, we investigated the association of 222 haplotype-tagging single-nucleotide polymorphisms (SNPs) in eight phospholipid-transporting ATPase genes with cancer-specific survival (CSS) and overall survival (OS) of 630 patients treated with androgen-deprivation therapy (ADT) for prostate cancer. RESULTS After multivariate Cox regression analysis and multiple testing correction, we found that ATP8B1 rs7239484 was remarkably associated with CSS and OS after ADT. A pooled analysis of multiple independent gene-expression datasets demonstrated that ATP8B1 was under-expressed in tumor tissues and that a higher ATP8B1 expression was associated with a better patient prognosis. Moreover, we established highly invasive sublines using two human prostate cancer cell lines to mimic cancer progression traits in vitro. The expression of ATP8B1 was consistently downregulated in both highly invasive sublines. CONCLUSION Our study indicates that rs7239484 is a prognostic factor for patients treated with ADT and that ATP8B1 can potentially attenuate prostate cancer progression.

Abstract
Androgen-deprivation therapy (ADT) is the primary systemic therapy for treating advanced or metastatic prostate cancer (PCa), which has improved survival outcomes in patients with PCa. However, ADT may develop metabolic and cardiovascular adverse events that impact the quality of life and lifespan in PCa survivors. The present study was designed to establish a murine model of ADT with a gonadotropin-releasing hormone (GnRH) agonist leuprolide and to investigate its effects on metabolism and cardiac function. We also examined the potential cardioprotective role of sildenafil (inhibitor of phosphodiesterase 5) under chronic ADT. Middle-aged male C57BL/6J mice received a 12-wk subcutaneous infusion via osmotic minipumps containing either saline or 18 mg/4 wk leuprolide with or without 1.3 mg/4 wk sildenafil cotreatment. Compared with saline controls, leuprolide treatment significantly reduced prostate weight and serum testosterone levels, confirming chemical castration in these mice. The ADT-induced chemical castration was not affected by sildenafil. Leuprolide significantly increased the weight of abdominal fat after 12-wk treatment without a change in total body weight, and sildenafil did not block the proadipogenic effect of leuprolide. No signs of left ventricular systolic and diastolic dysfunction were observed throughout the leuprolide treatment period. Interestingly, leuprolide treatment significantly elevated serum levels of cardiac troponin I (cTn-I), a biomarker of cardiac injury, and sildenafil did not abolish this effect. We conclude that long-term ADT with leuprolide increases abdominal adiposity and cardiac injury biomarker without cardiac contractile dysfunction. Sildenafil did not prevent ADT-associated adverse changes.

Abstract
Most patients with metastatic prostate cancer (mPCa) are older. In addition, current geriatric oncology guidelines suggest that all cancer patients aged over 70 years should undergo a comprehensive geriatric assessment (CGA), with the identification of frailty syndrome being crucial for clinical decisions. Frailty can be associated with lower quality of life (QoL) and interfere with the feasibility or side effects of oncology treatments. METHODS We performed a systematic literature search to evaluate frailty syndrome and associated alterations related to CGA impairment by searching in different academic databases (PubMed, Embase, and Scopus). The identified articles were reviewed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Of the 165 articles consulted, 7 met our inclusion criteria. Analysis of data related to frailty syndrome in patients with mPCa showed a prevalence between 30-70% depending on the tool used. Additionally, frailty was associated with other CGA assessments and QoL evaluation outcomes. In general terms, CGA scores for patients with mPCa were lower than those for patients without metastasis. Furthermore, functional QoL appeared to be worse for patients with metastasis, and global QoL (burden) was more strongly associated with frailty. CONCLUSION Frailty syndrome was related to a poorer QoL in patients with mPCa and its evaluation should be considered in clinical decision-making and when choosing the most appropriate active treatment, if any, to increase survival.

Abstract
OBJECTIVE Due to the fear generated by COVID-19 in Spring 2020, many patients postponed their scheduled outpatient visits. To differentiate those patients with prostate cancer (PCa) whose androgen deprivation therapy (ADT) injection treatment can be postponed, we investigated the characteristics of testosterone (T) recovery in Japanese patients after they received combined ADT and radiation therapy (RT). METHODS We included 81 patients with PCa treated with ADT and RT at Keio University Hospital from January 2013 to December 2018. T-recovery was defined as the time interval between the last ADT injection and 3-6 months after T-normalization. The Kaplan-Meier method was used to estimate time to T-recovery. Cox proportional hazards models identified T-recovery predictors. RESULTS The 50% cumulative incidence of T-recovery was 7.0 months for the 6-short-term group (defined as patients having ≤6 months of ADT therapy) versus 13.0 months for the 6-long-term group (>6 months of therapy) (p < 0.001). The incidence was 7.0 months for the 12 short-term-ADT (ST) group versus 18.0 months for the 12 long-term-ADT (LT) group (p < 0.001). Multivariate analysis revealed that a shorter duration of ADT was associated with a shorter time to T-recovery (hazard ratio, 0.253; 95% CI, 0.138-0.465; p < 0.001). No other factors were significant predictors of T-recovery. CONCLUSION Androgen deprivation therapy duration is significantly associated with T-recovery in Japanese patients with PCa. If a patient undergoes ADT for more than 6 or 12 months, it is possible to postpone their outpatient visits for 13 and 18 months, respectively.

Abstract
BACKGROUND/AIM No practical predictive biomarkers exist to date for the response to androgen receptor-axis targeted (ARAT) therapies in metastatic castration-resistant prostate cancer (mCRPC). This study investigated whether prostate-specific antigen (PSA) kinetics in primary androgen-deprivation therapy for advanced hormone-sensitive prostate cancer may be associated with the response to ARAT agents in mCRPC. PATIENTS AND METHODS This study assessed 102 patients with mCRPC treated with enzalutamide or abiraterone to evaluate the associations between clinical outcomes and PSA kinetics, including the ratio of initial to nadir PSA (I/N PSA) level in primary combined androgen blockade. The PSA response was defined as a ≥50% decrease at 3 months from baseline in patients with mCRPC. RESULTS In patients treated with enzalutamide, the optimal cut-off I/N PSA value for PSA response was 531 ng/ml (sensitivity=66.7%, specificity=88.2%, area under the curve=0.73, using a receiver operating characteristic curve). The PSA response was 83.3% and 25.0% in the high and low I/N PSA groups, respectively. The median overall survival and radiographic progression-free survival from enzalutamide initiation were longer for the high compared to the low I/N PSA group. Multivariate analysis revealed I/N PSA (hazard ratio=0.275, p=0.026) as an independent risk factor for overall survival in the patients treated with enzalutamide. In contrast, I/N PSA showed no predictive ability for PSA response in patients treated with abiraterone. CONCLUSION In patients with mCRPC, I/N PSA can be a practical predictive biomarker for response to the ARAT agent enzalutamide.

Abstract
Metabolic abnormalities as side effects of androgen-deprivation therapy (ADT) can accelerate progression of prostate cancer (PCa) and increase risks of cardiovascular diseases. A healthy dietary pattern (DP) plays an important role in regulating glycolipid metabolism, while evidence about DP on ADT-related metabolic abnormalities is still controversial. To explore the effect of DP on metabolic outcomes in PCa patients with ADT, PubMed, Embase, Cochrane, and CINAHL were searched from inception to 10 September 2022. Risk of biases was evaluated through Cochrane Collaboration’s Tool. If heterogeneity was low, the fixed-effects model was carried out; otherwise, the random-effects model was used. Data were determined by calculating mean difference (MD) or standardized MD (SMD) with 95% confidence intervals (CIs). Nine studies involving 421 patients were included. The results showed that healthy DP significantly improved glycated hemoglobin (MD: −0.13; 95% CI: −0.24, −0.02; p = 0.020), body mass index (MD: −1.02; 95% CI: −1.29, −0.75; p < 0.001), body fat mass (MD: −1.78; 95% CI: −2.58, −0.97; p < 0.001), triglyceride (MD: −0.28; 95% CI: −0.51, −0.04; p = 0.020), systolic blood pressure (MD: −6.30; 95% CI: −11.15, −1.44; p = 0.010), and diastolic blood pressure (MD: −2.94; 95% CI: −5.63, −0.25; p = 0.030), although its beneficial effects on other glycolipid metabolic indicators were not found. Additionally, a healthy DP also lowered the level of PSA (MD: −1.79; 95% CI: −2.25, −1.33; p < 0.001). The meta-analysis demonstrated that a healthy DP could improve ADT-related metabolic abnormalities and be worthy of being recommended for PCa patients with ADT.

Abstract
WHAT IS THIS SUMMARY ABOUT? This is a summary of a research study (known as a clinical trial) called HERO. The HERO study compared how well relugolix and leuprolide worked in lowering blood testosterone to sustained castration levels in men with advanced prostate cancer. Sustained castration is a blood testosterone level below 50 ng/dl from Day 29 through 48 weeks of treatment. WHAT WERE THE RESULTS? Researchers looked at 930 adult men with advanced prostate cancer: 622 of these men took relugolix (by mouth once daily) and 308 received leuprolide (injected every 3 months). The HERO study showed that more men taking relugolix (97%) achieved sustained castration through 48 weeks than men receiving leuprolide (89%). This decrease in testosterone also happened more quickly in men taking relugolix. In 184 men who were followed up for 90 days after completing treatment, blood levels of testosterone returned to normal in more men who took relugolix than men who received leuprolide. Side effects were similar among men taking relugolix or receiving leuprolide, and most were identified as mild or moderate in terms of how bad they were. WHAT DO THE RESULTS OF THE STUDY MEAN? In men with advanced prostate cancer and compared with those receiving leuprolide, more men taking relugolix had lower levels of blood testosterone. ClinicalTrials.gov NCT number: NCT03085095.

Abstract
The treatment for lymph node involvement (LNI) after radical prostatectomy (RP) has not been established. This study aimed to reveal the outcomes of various management strategies among patients with LNI after RP. Retrospectively, 561 patients with LNI after pelvic lymph node dissection (PLND) with RP treated between 2006 and 2019 at 33 institutions participating in the Japanese Urological Oncology Group were investigated. Metastasis-free survival (MFS) was the primary outcome. Patients were stratified by PSA persistence after RP. Cox regression models were used to analyze the relationships between clinicopathological characteristics and survival. Survival analyses were conducted using the Kaplan-Meier method and log-rank test with or without propensity score matching. Prognoses, including MFS and overall survival, were prominently inferior among patients with persistent PSA than among those without persistent PSA. In multivariate analysis, androgen-deprivation therapy (ADT) plus radiotherapy (RT) was associated with better MFS than ADT alone among patients with persistent PSA (hazard ratio = 0.37; 95% confidence interval = 0.15-0.93; P = 0.034). Similarly, MFS and overall survival were significantly better for ADT plus RT than for ADT alone among patients with persistent PSA after propensity score matching. This study indicated that PSA persistence in LNI prostate cancer increased the risk of poor prognoses, and intensive treatment featuring the addition of RT to ADT might improve survival.

Abstract
Ribosomal S6 kinase has been shown to play a key role in cellular resistance to endocrine therapy in prostate cancer through its regulation of YB‐1/androgen receptor (AR) signaling. PMD‐026, an oral first‐in‐class small molecule kinase inhibitor, is the first identified ribosomal S6 kinase inhibitor. This study investigated the effect of PMD‐026 on YB‐1/AR signaling and its antitumor effect in prostate cancer in vitro and in vivo. Castration‐resistant prostate cancer 22Rv1 cells that express high‐level AR variants were used in this study. The effect of PMD‐026 on YB‐1/AR signaling was investigated by quantitative real‐time PCR and western blot analysis. The effects of PMD‐026 on prostate cancer cells were investigated by cytotoxicity analysis, apoptosis assay, and cell cycle assay in vitro and a mouse castration model in vivo. PMD‐026 decreased YB‐1 phosphorylation as well as AR V7 mRNA and AR variant expressions in 22Rv1 cells. PMD‐026 suppressed cell proliferation alone and in combination with the second‐generation antiandrogens enzalutamide and darolutamide by inducing cellular apoptosis and G2/M arrest. In a mouse xenograft model, PMD‐026 suppressed tumor growth, and the combination of PMD‐026 and enzalutamide inhibited tumor growth more prominently than single treatments. Our results demonstrate an excellent antitumor effect of the novel ribosomal S6 kinase inhibitor PMD‐026 and the combination effect with the antiandrogen enzalutamide in castration‐resistant prostate cancer. These findings warrant a clinical trial of PMD‐026 in prostate cancer patients.

Abstract
Androgen-deprivation therapy (ADT) is the cornerstone of metastatic prostate cancer treatment. ADT can be achieved through surgical castration, or it may be induced either by gonadotrophin-releasing hormone (GnRH) agonists or GnRH antagonists. GnRH antagonists provide a more rapid castration alongside with a safer profile regarding adverse events. Degarelix is the sole GnRH antagonist used in clinical practice. Injection site reactions are the commonest adverse events related to the use of degarelix. Relugolix, a novel molecule, represents the first orally administered United States Food and Drug Administration approved GnRH antagonist, with clinical efficacy equal to that of the established ADT regimens. The main advantages of relugolix are the avoidance of the injection site reactions of GnRH antagonists such as degarelix alongside its patient-friendly oral administration. The aim of the present review article is to present novel data regarding the role of relugolix as ADT for the treatment of prostate cancer.

Abstract
This study aimed to investigate the significance of HSD3B1 gene status including germline polymorphism and somatic alterations in prostate cancer. Patients with prostate cancer treated with androgen-deprivation therapy, as well as tissues from metastatic prostate cancer, were included. Genomic DNA was extracted from cancer tissues and whole blood samples, and HSD3B1 (rs1047303, 1245C) was genotyped by Sanger sequencing. The association of HSD3B1 genotype with progression-free survival according to metastatic volume was examined. Copy number alteration and gene expression of HSD3B1 were examined in prostate cancer cells and public datasets. Among 194 patients, 121 and 73 patients were categorized into low- and high-volume diseases respectively. In multivariate analysis, the adrenal-permissive genotype (AC/CC) was significantly associated with increased risk of progression compared with the adrenal-restrictive genotype (AA) in low volume, but not high-volume diseases. Somatic mutation in HSD3B1 was detected at least in two cases of castration-resistant prostate cancer tissues. HSD3B1 amplification and overexpression were detected in castration-resistant prostate cancer cells and tissues. The current findings suggest that both germline and somatic alterations of HSD3B1 may cooperatively promote castration resistance in prostate cancer and HSD3B1 as a promising biomarker for precision medicine, warranting further investigations.

Abstract
BACKGROUND/AIM To explore the prognostic value of lower urinary tract symptoms (LUTS) in patients with newly diagnosed regional lymph node-positive prostate cancer. PATIENTS AND METHODS The prognostic value of LUTS for progression-free (PFS) and overall (OS) survival, as well as the differential prognostic impact of radiotherapy by LUTS was investigated. RESULTS Univariate Cox-model analysis showed a statistically significantly increased hazard risk for PFS and OS for men with International Prostate Symptom Score (IPSS)≥19 and Overactive Bladder Symptom Score (OABSS) ≥8 at diagnosis. Patients with lower IPSS had a better PFS at 5 years (70.0% vs. 51.9%, p=0.027) and OS at 5 year (89.3% vs. 73.6%, p=0.016). Similarly, a lower OABSS was associated with greater PFS at 5 years (67.4% vs. 23.4%, p<0.001) and OS at 5 years (85.3% vs. 57.1%, p=0.012). CONCLUSION IPSS and OABSS were prognostic for PFS and OS in patients with regional lymph node-metastatic prostate cancer.

Abstract
OBJECTIVE To investigate whether bipolar androgen therapy (BAT), involving rapid cyclic administration of high-dose testosterone, as a novel treatment for metastatic castration-resistant prostate cancer (mCRPC) promotes improvements in body composition and associated improvements in lipid profiles and quality of life. PATIENTS AND METHODS Men from two completed trials with computed tomography imaging at baseline and after three cycles of BAT were included. Cross-sectional areas of psoas muscle, visceral and subcutaneous fat were measured at the L3 vertebral level. Functional Assessment of Chronic Illness Therapy - Fatigue questionnaire and 36-item short-form health survey were used to assess quality of life. RESULTS The 60 included patients lost a mean (sd) of 7.8 (8.2)% of subcutaneous fat, 9.8 (18.2)% of visceral fat, and gained 12.2 (6.7)% muscle mass. Changes in subcutaneous and visceral fat were positively correlated with each other (Spearman's correlation coefficient 0.58, 95% confidence interval 0.35-0.71) independent of the effects of age, body mass index, and duration of androgen-deprivation therapy. Energy, physical function, and measures of limitations due to physical health were all significantly improved at 3 months. The improvements in body composition were not correlated with decreases in lipid levels or observed improvements in quality of life. CONCLUSIONS In the present study, BAT was associated with significant improvements in body composition, lipid parameters, and quality of life. This has promising implications for the long-term health of men with mCRPC.

Abstract
The metastatic burden is a critical factor for decision-making in the treatment of metastatic hormone-sensitive prostate cancer (HSPC). This study aimed to develop and validate a novel risk model for survival in patients with de novo low- and high-burden metastatic HSPC. The retrospective observational study included men with de novo metastatic prostate cancer who were treated with primary androgen-deprivation therapy at 30 institutions across Japan between 2008 and 2017. We created a risk model for overall survival (OS) in the discovery cohort (n = 1449) stratified by the metastatic burden (low vs high) and validated its predictive ability in a separate cohort (n = 951). Based on multivariate analyses, lower hemoglobin levels, higher Gleason grades, and higher clinical T-stage were associated with poor OS in low-burden disease. Meanwhile, lower hemoglobin levels, higher Gleason grade group, liver metastasis, and higher extent of disease scores in bone were associated with poor OS in patients with high-burden disease. In the discovery and validation cohorts, the risk model using the aforementioned parameters exhibited excellent discriminatory ability for progression-free survival and OS. The predictive ability of this risk model was superior to that of previous risk models. Our novel metastatic burden-stratified risk model exhibited excellent predictive ability for OS, and it is expected to have several clinical uses, such as precise prognostic estimation.

Abstract
BACKGROUND/AIM Currently, there is no established prognostic serum parameter except PSA in clinically regional lymph node-positive prostate cancer. The aim of this study was to identify serum prognostic factors in clinically regional lymph node-positive prostate cancer. PATIENTS AND METHODS Patients diagnosed with regional lymph node-positive prostate cancer between 2008 and 2017 were included. The prognostic value of serum parameters for progression-free survival (PFS) and overall survival (OS) was investigated. RESULTS Univariate and multivariate analyses showed a statistically significant increased hazard risk for PFS and OS for men with lactate dehydrogenase (LDH) ≥230 IU/l at diagnosis. PFS at 5 years for patients with high and low LDH levels were 69.9% (95% CI=56.8-79.8%) and 18.9% (95% CI=1.23-53.2%), respectively (p=0.003). OS at 5 years for low and high LDH levels were 89.2% (95% CI=78.6-94.7%) and 46.3 (95% CI=11.2-76.2%), respectively (p=0.006). CONCLUSION This study shows that LDH is an independent predictor of PFS and OS in patients with regional lymph node metastatic prostate cancer.

Abstract
Bone health impairment is a frequent detrimental consequence of the high bone tropism of prostate cancer (PCa) cells. It is further worsened by administration of androgen-deprivation therapy (ADT), the current standard of care in the management of advanced PCa, through a rapid and dramatic increase in bone turnover and body mass changes. As a result, patients may experience substantial pain and poor quality of life (QoL) and have an increased risk of death. Notwithstanding the importance of this issue, however, bone health preservation is not yet a widespread clinical goal in daily practice. To address this urgent unmet need, following a thorough discussion of available data and sharing of their clinical practice experience, a panel of Italian experts in the field of bone health and metabolism formulated a number of practical advices for optimising the monitoring and treatment of bone health in men undergoing ADT during all phases of the disease. The rationale behind the venture was to raise awareness on the importance of bone preservation in this complex setting, while providing an instrument to support physicians and facilitate the management of bone health. Current evidence regarding the effects on bone health of ADT, of novel hormone therapies (which improve progression delay, pain control and QoL while consistently carrying the risk of non-pathological fractures in both non-metastatic and metastatic PCa) and of bone turnover inhibitors (whose use is frequently suboptimal) is reviewed. Finally, the expert opinion to optimise bone health preservation is given.

Abstract
Androgen deprivation therapy or ADT is one of the cornerstones of management of locally advanced or metastatic prostate cancer, alongside radiation therapy. However, despite early response, most advanced prostate cancers progress into an androgen unresponsive or castrate resistant state, which hitherto remains an incurable entity and the second leading cause of cancer-related mortality in men in the US. Recent advances have uncovered multiple complex and intermingled mechanisms underlying this transformation. While most of these mechanisms revolve around androgen receptor (AR) signaling, novel pathways which act independently of the androgen axis are also being discovered. The aim of this article is to review the pathophysiological mechanisms that help bypass the apoptotic effects of ADT to create castrate resistance. The article discusses castrate resistance mechanisms under two categories: 1. Direct AR dependent pathways such as amplification or gain of function mutations in AR, development of functional splice variants, posttranslational regulation, and pro-oncogenic modulation in the expression of coactivators vs corepressors of AR. 2. Ancillary pathways involving RAS/MAP kinase, TGF-beta/SMAD pathway, FGF signaling, JAK/STAT pathway, Wnt-Beta catenin and hedgehog signaling as well as the role of cell adhesion molecules and G-protein coupled receptors. miRNAs are also briefly discussed. Understanding the mechanisms involved in the development and progression of castration-resistant prostate cancer is paramount to the development of targeted agents to overcome these mechanisms. A number of targeted agents are currently in development. As we strive for more personalized treatment across oncology care, treatment regimens will need to be tailored based on the type of CRPC and the underlying mechanism of castration resistance.

Abstract
BACKGROUND The addition of androgen-deprivation therapy (ADT) or pelvic radiation to prostate bed salvage radiotherapy (SRT) has been debated for prostate cancer patients with biochemical recurrence (BCR) after radical prostatectomy. This study aimed to assess the outcomes and propose prediction models for exclusive prostate bed SRT. METHODS This is a prospective observational cohort study with patients who underwent SRT with a pre-SRT PSA < 1.5 ng/mL after radical prostatectomy. Patients were treated with 70-Gy SRT to the prostate bed exclusively. Kaplan-Meier survival analyses and Cox regression analyses were applied for depicting and predicting BCR-free survival, ADT-free survival, and metastasis-free survival (MFS). Regression-based coefficients were used to develop nomograms. RESULTS A total of 105 patients were included and 91 patients were eligible. The median follow-up period was 39 months. The 5-year BCR-free survival, ADT-free survival, and MFS were 37%, 50%, and 66%, respectively. Multivariable analysis showed that a pre-SRT PSA < 0.45 ng/mL was the only independent factor associated with longer BCR-free survival (p = 0.034), while a PSA-DT > 8 months had better ADT-free survival (p = 0.008). Patients with a PSA-DT > 8 months showed a 100% MFS and a 43% 5-year absolute benefit in MFS than a PSA-DT ≤ 8 months. All patients with a pre-SRT PSA < 0.45 ng/mL and PSA-DT > 8 months were free from subsequent ADT and any metastasis. CONCLUSIONS In patients with a PSA < 0.45 ng/mL and PSA-DT > 8 months for post-prostatectomy BCR, prostate bed SRT provided excellent outcomes without the need for concomitant ADT or pelvic radiotherapy.

Abstract
Transforming growth factor-β1 (TGF-β1) plays a dual role in cancer, acting as a tumor suppressor in the early stage of cancer development and as a tumor promoter in the later stage of cancer progression in various cancers. In this study, we investigated the association between genetic polymorphisms in TGFB1 and clinicopathological characteristics or oncological outcome in prostate cancer cases treated with androgen-deprivation therapy (ADT) according to metastasis status. Japanese male patients with hormone-sensitive prostate cancer treated with ADT from 1993 to 2005 were included in this study. Genomic DNA was obtained from whole blood samples, and genotyping of TGFB1 (rs2241716 and rs4803455) was performed by PCR-based technique. No significant association between genetic polymorphisms in TGFB1 (rs2241716 and rs4803455) and clinicopathological parameters or prognosis was observed in patients with non-metastatic disease. In patients with metastatic disease, Gleason score in CT/TT carriers (rs2241716) and CA/AA carriers (rs4803455) was unfavorable compared with CC carriers. In addition, the CT/TT alleles in rs2241716 (hazard ratio, 1.82; 95% confidence interval, 1.12–2.94; P = 0.015) and the CA/AA alleles in rs4803455 (hazard ratio, 1.75; 95% confidence interval, 1.03–2.98; P = 0.040) were associated with a higher risk of progression during ADT compared with the CC allele in patients with metastatic disease. TGFB1 genetic variations were associated with adverse characteristics and progression risk in ADT among patients with metastatic disease, but not those with non-metastatic disease, supporting a distinct role of TGF-β signaling between non-metastatic and metastatic prostate cancer.

Abstract
Neuregulins (NRGs) activate receptor tyrosine kinases of the ErbB family, and play essential roles in the proliferation, survival, and differentiation of normal and malignant tissue cells. We hypothesized that genetic variants of NRG signalling pathway genes may influence treatment outcomes in prostate cancer. To test this hypothesis, we performed a comprehensive analysis to evaluate the associations of 459 single-nucleotide polymorphisms in 19 NRG pathway genes with cancer-specific survival (CSS), overall survival (OS), and progression-free survival (PFS) in 630 patients with prostate cancer receiving androgen-deprivation therapy (ADT). After multivariate Cox regression and multiple testing correction, we found that NRG1 rs144160282 C > T is significantly associated with worsening CSS, OS, and PFS during ADT. Further analysis showed that low expression of NRG1 is closely related to prostate cancer, as indicated by a high Gleason score, an advanced stage, and a shorter PFS rate. Meta-analysis of 16 gene expression datasets of 1,081 prostate cancer samples and 294 adjacent normal samples indicate lower NRG1 expression in the former compared with the latter (p < 0.001). These results suggest that NRG1 rs144160282 might be a prognostic predictor of the efficacy of ADT. Further studies are required to confirm the significance of NRG1 as a biomarker and therapeutic target for prostate cancer.

Abstract
Metastatic burden is a critical factor for therapy decision-making in metastatic hormone-sensitive prostate cancer. The present study aimed to identify prognostic factors in men with high- or low-metastatic burden treated with primary androgen-deprivation therapy. The study included 2450 men with de novo metastatic prostate cancer who were treated with primary androgen-deprivation therapy at 30 institutions across Japan between 2008 and 2017. We investigated the prognostic value of various clinicopathological parameters for progression-free survival (PFS) and overall survival (OS) in patients stratified by low- or high-metastatic burden. Among the 2450 men, 841 (34.3%) and 1609 (65.7%) were classified as having low- and high-metastatic burden, respectively. Median PFS of the low- and high-burden groups were 44.5 and 16.1 months, respectively, and the median OS was 103.2 and 62.7 months, respectively. Percentage of biopsy-positive core, biopsy Gleason grade group, T-stage, and N-stage were identified to be differentially prognostic. M1a was associated with worse PFS than was M1b in the low-burden group, whereas lung metastasis was associated with better PFS and OS than was M1b in the high-burden group. Differential prognostic factors were identified for patients with low- and high-burden metastatic prostate cancer. These results may assist in decision-making to select the optimal therapeutic strategies for patients with different metastatic burdens.

Abstract
The relationship between cognitive decline and androgen deprivation therapy (ADT) under luteinizing hormone-releasing hormone (LHRH) analogues is unclear, and there is a scarcity of longitudinal studies considering the interaction between cognition, depressive symptoms and sleep quality in men with prostate cancer (PCa) treated with ADT. This study aimed to determine if there were differences in the scores obtained in cognitive assessment, depressive symptoms, and sleep quality after one year of ADT and determine the interrelations between sleep, mood, and cognitive status. A prospective longitudinal observational study was designed, in which a cohort of men (mean age was 70.8 years) newly treated with androgen-deprivation therapy was assessed in the first six months of treatment and 12 months later. Analysis of cognitive function by the Mini-Mental State Examination (MMSE) scores indicated a significant (p < 0.05) increase after one year of treatment and by the Brief Scale for Cognitive Evaluation (BCog) scores indicated no changes in the scores before and after one year of treatment. Analysis of depressive symptoms with the Geriatric Depression Scale and sleep quality with the Athens Insomnia Scale (AIS) scores showed significant (p < 0.05) changes after one year of treatment with ADT, with men describing more depressive symptoms and more sleep disturbances. No statistically significant differences were found in the cognitive performance between men with impaired sleep or depression results and those without them. Our study showed no clinical evidence of the relationship between ADT under luteinizing hormone-releasing hormone (LHRH) analogues and cognitive deterioration in 1-year follow-up, but there are impairments in the sleep quality in men with PCa undergoing ADT and an increase in depressive symptoms which has important implications for clinicians as they would impair quality of life and adherence to treatment.

Abstract
BACKGROUND The 23-valent pneumococcal polysaccharide vaccine (PPSV23) is indicated for adults who have a high risk of pneumonia; however, its effectiveness in patients with prostate cancer who are at a risk of pneumonia because of age and cancer treatments, including androgen-deprivation therapy, is unknown. METHODS Between 2000 and 2010, 38,735 patients with prostate cancer were diagnosed in Taiwan. After exclusions and exact matching for age, previous pneumonia, and influenza vaccination, 2188 vaccinated patients and 2188 unvaccinated patients were recruited. The incidence density of all-cause bacterial pneumonia hospitalizations was analyzed. RESULTS Over 7 years of follow-up, patients who received the PPSV23 had a significantly lower incidence density, with 142.8 per 1000 person-years versus 162.0 per 1000 person-years for unvaccinated patients. More patients in the vaccinated cohort were never hospitalized for pneumonia compared with those in the unvaccinated cohort (64.2% vs 62.2%, respectively). After adjusting for the Charlson comorbidity index, cancer treatment modalities, and socioeconomic levels, the risk of pneumonia-related hospitalization in the PPSV23 vaccination cohort was 0.48 times lower than that in the unvaccinated cohort (adjusted incidence rate ratio, 0.48; P = .046). For patients who received the influenza vaccination, subgroup analysis demonstrated that PPSV23 vaccination significantly decreased the risk (adjusted incidence rate ratio, 0.45; P < .001). Compared with unvaccinated controls, PPSV23-vaccinated patients had a lower cumulative incidence for the first occurrence of pneumonia-related hospitalization (34.49% vs 36.36%; P = .178) and higher overall survival (47.5% and 42.3%, respectively; P < .001). CONCLUSIONS Vaccination of elderly patients who have prostate cancer with the relatively common and inexpensive PPSV23 can decrease the risk of pneumonia and prolong survival.

Abstract
Objective: To compare the efficacy and safety of current systemic combination therapies for patients with mHSPC and help select candidates for optimal treatment. Methods: Databases of MEDLINE and EMBASE, Cochrane Central Register of Controlled Trials, and Clinical Trial.gov were searched for eligible studies. Direct and network meta-analysis were conducted to compare various systemic combination therapies and the surface under the cumulative ranking curve (SUCRA) was generated for treatment ranking. Subgroup analyses were performed according to the extent of metastasis. Adverse events (AEs) were compared among the effective treatments. Results: Ten trials with 16 publications were included in this network meta-analysis. Direct and network meta-analysis consistently suggested that androgen-deprivation therapy (ADT) combined with docetaxel, abiraterone, enzalutamide, or apalutamide could significantly improve overall survival (OS) and failure-free survival (FFS) compared to ADT alone in men with mHSPC. SUCRA analysis demonstrated the superiority of ADT plus abiraterone or enzalutamide over other therapies. Subgroup analyses indicated that additional abiraterone to ADT had the highest ranking in patients with high-volume diseases or visceral metastases and enzalutamide plus ADT outperformed other treatments in patients with low-volume diseases or without visceral metastases. Different combination therapies had variable AE profiles and ADT in addition with docetaxel or abiraterone had the highest risk of AEs. Conclusion: ADT plus docetaxel, abiraterone, enzalutamide, or apalutamide were associated with significantly improved survival in patients with mHSPC. ADT plus abiraterone or enzalutamide appeared to be the most effective treatments. Clinicians should balance the efficacy, potential AEs, and disease status to select the optimal treatment.

Abstract
Immunotherapy has shown limited success in prostate cancer; this may be partially explained by its immunosuppressive tumor microenvironment (TME). Although androgen-deprivation therapy (ADT), the most common treatment for prostate cancer, initially promotes a robust T cell infiltrate, T cell responses are later attenuated. Based on the castration-sensitive Myc-CaP model, we developed an antigen-specific system to study CD8 T cell tolerance to prostate tumors. This model is unique in that CD8 T cells recognize a bona-fide tumor antigen (Her-2/neu), rather than an overexpressed xenogenic antigen like chicken ovalbumin or influenza hemagglutinin. Using this novel model, we demonstrate robust tolerance that is not alleviated by TLR agonists or ADT. This model may serve as a novel and useful tool to further interrogate methods by which to augment anti-tumor cancer immune responses to prostate cancer. Significance Prostate cancer is a leading cause of cancer-related death in men worldwide, with an estimated 33,000 deaths projected in the U.S. in 2020. Although primary (localized) tumors can be cured by surgery or radiation, approximately 40% of patients eventually develop recurrent disease. While initially responsive to androgen-deprivation, many patients with recurrent prostate cancer eventually progress to a more advanced disease state known as metastatic castration-resistant prostate cancer (mCRPC); this is the lethal phenotype. These studies describe a novel androgen-responsive murine cell line that expresses a bona-fide tumor antigen (Her-2/neu). Pre-clinical work with this model shows robust and antigen-specific CD8 T cell tolerance, providing a novel preclinical model to study CD8 T cell tolerance to prostate tumors.

Abstract
The novel coronavirus disease 2019 (COVID-19) shows a wide spectrum of clinical presentations, severity, and fatality rates. The reason older patients and males show increased risk of severe disease and death remains uncertain. Sex hormones, such as estradiol, progesterone, and testosterone, might be implicated in the age-dependent and sex-specific severity of COVID-19. High testosterone levels could upregulate transmembrane serine protease 2 (TMPRSS2), facilitating the entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) into host cells via angiotensin-converting enzyme 2 (ACE2). Data from patients with prostate cancer treated with androgen-deprivation therapy seem to confirm this hypothesis. Clinical studies on TMPRSS2 inhibitors, such as camostat, nafamostat, and bromhexine, are ongoing. Antiandrogens, such as bicalutamide and enzalutamide, are also under investigation. Conversely, other studies suggest that the immune modulating properties of androgens could protect from the unfavorable cytokine storm, and that low testosterone levels might be associated with a worse prognosis in patients with COVID-19. Some evidence also supports the notion that estrogens and progesterone might exert a protective effect on females, through direct antiviral activity or immune-mediated mechanisms, thus explaining the higher COVID-19 severity in post-menopausal women. In this perspective, we discuss the available evidence on sex hormones and hormone therapy in patients infected with SARS-CoV-2, and we highlight the possible implications for cancer patients, who can receive hormonal therapies during their treatment plans.

Abstract
Apalutamide, a competent inhibitor of the androgen receptor, has shown promising clinical efficacy results for patients with advanced prostate cancer. Here, we describe the rationale and design for the SAVE trial, a multi-center, Phase II study, wherein 202 men with biochemical progression after radical prostatectomy are randomly assigned 1:1 to apalutamide plus salvage radiotherapy (SRT) or androgen-deprivation therapy with an luteinizing hormone-releasing hormone agonist or antagonist plus SRT. The primary objective is to compare sexual function between the two treatment arms based on the expanded prostate cancer index-26 sexual domain score at nine months after start of hormonal treatment. The key secondary objectives are to assess quality of life, to evaluate the safety profile and the short-term efficacy of apalutamide in combination with SRT.

Abstract
Objective Our aim was to provide practical recommendations on the management of patients with metastatic castration-resistant prostate cancer (mCRPC) who have progressed after docetaxel plus androgen-deprivation therapy (ADT) or abiraterone plus ADT. Methods Systematic literature review (SLR), nominal group meeting, and Delphi process. A panel of 12 experts was established who defined the scope, users, and sections of the document. We performed an SLR in order to assess the efficacy and safety of available drugs in patients with mCRPC. Abstracts from the American Society of Oncology and European Society for Medical Oncology meetings were also examined. The results were discussed during an expert meeting in which 14 recommendations were generated. The level of agreement with the recommendations was also tested by 13 additional experts following the Delphi process. Recommendations were voted by means of scores ranging from 0 (total disagreement) to 10 (total agreement). We defined agreement when at least 70% of the experts voted ⩾7. Next, we assigned a level of evidence and grade to the recommendation using the Oxford Centre for Evidence-based Medicine Levels of Evidence, following which the final document was drafted. Results The literature search did not find any articles meeting the inclusion criteria. Finally, 13 out of 14 recommendations were accepted after two Delphi rounds (two were modified after the first round). They pertain to general and individual case-based treatment recommendations. Conclusions In mCRPC patients who have progressed after docetaxel or abiraterone plus ADT in the metastatic hormone-sensitive prostate cancer setting, these recommendations may support treatment decision-making, due to the lack of evidence or other globally accepted sequencing algorithms.

Abstract
Background Cell entry of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) depends on binding of the viral spike (S) proteins to angiotensin-converting enzyme 2 and on S protein priming by TMPRSS2. Inhibition of TMPRSS2 may work to block or decrease the severity of SARS-CoV-2 infections. Intriguingly, TMPRSS2 is an androgen-regulated gene that is up-regulated in prostate cancer where it supports tumor progression and is involved in a frequent genetic translocation with the ERG gene. First- or second-generation androgen-deprivation therapies (ADTs) decrease the levels of TMPRSS2. Here we put forward the hypothesis that ADTs may protect patients affected by prostate cancer from SARS-CoV-2 infections. Materials and methods We extracted data regarding 9280 patients (4532 males) with laboratory-confirmed SARS-CoV-2 infection from 68 hospitals in Veneto, one of the Italian regions that was most affected by the coronavirus disease 2019 (COVID-19) pandemic. The parameters used for each COVID-19-positive patient were sex, hospitalization, admission to intensive care unit, death, tumor diagnosis, prostate cancer diagnosis, and ADT. Results There were evaluable 9280 SARS-CoV-2-positive patients in Veneto on 1 April 2020. Overall, males developed more severe complications, were more frequently hospitalized, and had a worse clinical outcome than females. Considering only the Veneto male population (2.4 million men), 0.2% and 0.3% of non-cancer and cancer patients, respectively, tested positive for SARS-CoV-2. Comparing the total number of SARS-CoV-2-positive cases, prostate cancer patients receiving ADT had a significantly lower risk of SARS-CoV-2 infection compared with patients who did not receive ADT (OR 4.05; 95% CI 1.55–10.59). A greater difference was found comparing prostate cancer patients receiving ADT with patients with any other type of cancer (OR 4.86; 95% CI 1.88–12.56). Conclusion Our data suggest that cancer patients have an increased risk of SARS-CoV-2 infections compared with non-cancer patients. However, prostate cancer patients receiving ADT appear to be partially protected from SARS-CoV-2 infections. SARS-CoV-2-infected men have a worse clinical outcome than women. Cancer patients have an increased risk of SARS-CoV-2 infection. Prostate cancer patients receiving androgen-deprivation therapies appear to be partially protected from the infection.

Abstract
BACKGROUND In men with castration-sensitive prostate cancer (CSPC), the HSD3B1 c.1245A>C variant has been reported to be associated with shorter responses to first-line androgen-deprivation therapy (ADT). Here, we evaluated the association between the inherited HSD3B1 c.1245A>C variant and outcomes from metastatic castration-resistant prostate cancer (mCRPC) after first-line treatment with abiraterone (Abi) or enzalutamide (Enza). PATIENTS AND METHODS Patients with mCRPC (n = 266) were enrolled from two centers at the time of starting first-line Abi/Enza. Outcomes after Abi/Enza included best prostate-specific antigen (PSA) response, treatment duration, and overall survival (OS). Outcomes after first-line ADT were determined retrospectively, and included treatment duration and OS. As was prespecified, we compared patients with the homozygous variant HSD3B1 genotype (CC genotype) versus the combined group with the heterozygous (AC) and homozygous wild-type (AA) genotypes. RESULTS Among the 266 patients, 22 (8.3%) were homozygous for the HSD3B1 variant (CC). The CC genotype had no association with PSA response rate; the median Abi/Enza treatment duration was 7.1 months for the CC group and 10.3 months for the AA/AC group (log rank P = 0.34). Patients with the CC genotype had significantly worse OS, with median survival at 23.6 months for the CC group and 30.7 months for the AA/AC group (log rank P = 0.02). In multivariable analysis adjusting for age, Gleason score, PSA, prior chemotherapy, and M1 disease, the association between the CC genotype and OS remained significant (hazard ratio 1.78, 95% confidence interval 1.03-3.07, P = 0.04). Poor outcome after first-line ADT in the CC group was also observed when evaluating retrospective ADT duration data for the same combined cohort. CONCLUSIONS In this large two-center study evaluating the HSD3B1 c.1245 genotype and outcomes after first-line Abi/Enza, homozygous variant (CC) HSD3B1 genotype was associated with worse outcomes. Novel therapeutic strategies are needed to enable treatment selection based on this genetic marker.

Abstract
OBJECTIVES (i) To assess whether exercise training attenuates the adverse effects of treatment in patients with newly diagnosed prostate cancer beginning androgen-deprivation therapy (ADT), and (ii) to examine whether exercise-induced improvements are sustained after the withdrawal of supervised exercise. PATIENTS AND METHODS In all, 50 patients with prostate cancer scheduled for ADT were randomised to an exercise group (n = 24) or a control group (n = 26). The exercise group completed 3 months of supervised aerobic and resistance exercise training (twice a week for 60 min), followed by 3 months of self-directed exercise. Outcomes were assessed at baseline, 3- and 6-months. The primary outcome was difference in fat mass at 3-months. Secondary outcomes included: fat-free mass, cardiopulmonary exercise testing variables, QRISK® 2 (ClinRisk Ltd, Leeds, UK) score, anthropometry, blood-borne biomarkers, fatigue, and quality of life (QoL). RESULTS At 3-months, exercise training prevented adverse changes in peak O2 uptake (1.9 mL/kg/min, P = 0.038), ventilatory threshold (1.7 mL/kg/min, P = 0.013), O2 uptake efficiency slope (0.21, P = 0.005), and fatigue (between-group difference in Functional Assessment of Chronic Illness Therapy-Fatigue score of 4.5 points, P = 0.024) compared with controls. After the supervised exercise was withdrawn, the differences in cardiopulmonary fitness and fatigue were not sustained, but the exercise group showed significantly better QoL (Functional Assessment of Cancer Therapy-Prostate difference of 8.5 points, P = 0.034) and a reduced QRISK2 score (-2.9%, P = 0.041) compared to controls. CONCLUSION A short-term programme of supervised exercise in patients with prostate cancer beginning ADT results in sustained improvements in QoL and cardiovascular events risk profile.

Abstract
Objectives: The present study aims to evaluate existing policy and practice relating to the use of pharmacological treatments with patients suffering from paraphilic disorders who are at risk of committing further sexual offences.Methods: A systematic literature search was conducted to document current legal policies across 26 different countries. In addition, a questionnaire assessing the practice of pharmacological treatment was sent to practitioners involved in the treatment of patients with paraphilic disorders.Results: Legal policies concerning the preconditions of using pharmacological treatments differ considerably between countries, and for most jurisdictions do not exist. Drawing on the responses of 178 practitioners, pharmacological agents are a useful addition to psychotherapeutic interventions, especially with those patients classified as medium or high risk for sexually violent behaviours. It would appear that most patients are medically examined, are informed of the risks and possible side effects before treatment commences and are also obliged to sign a consent form.Conclusions: Although pharmacological agents can be seen as an intrusion into a patients' sexual self determination, results indicate that ethical and clinical standards are being met in the majority of cases. However, further promotion of current WFSBP treatment guidelines would help to standardise practice across North American and European countries.

Abstract
Lysine specific demethylase 1 (LSD1) functions as a transcriptional repressor through demethylating active histone marks such as mono- or di-methylated histone 3 lysine 4 (H3K4) and interacting with histone deacetylases. However, LSD1 can also act as an activator through demethylating repressive histone marks and possibly non-histone proteins. In prostate cancer (PCa) cells, LSD1 mediates the transcriptional activity of androgen receptor (AR), a ligand dependent nuclear transcription factor that drives PCa initiation and progression to the castration-resistant prostate cancer (CRPC). However, it is unclear whether LSD1 also regulates other growth promoting pathways independent of AR signaling in PCa cells. In this study, we show that LSD1 can activate PI3K/AKT pathways in absence of androgen stimulation, and we further demonstrate that LSD1 transcriptionally regulates the expression of PI3K regulatory subunit, p85, possibly through epigenetic reprogramming of enhancer landscape in PCa cells. Our study suggests that LSD1 has dual functions in promoting PCa development, that it enhances AR signaling through its coactivator function, and that it activates PI3K/AKT signaling through increasing p85 gene expression.

Abstract
BACKGROUND Prostate cancer is the most frequently diagnosed cancer in men in the United States. There is scant real-world evidence characterizing the care utilization and clinical outcomes associated with the use of therapies currently approved by the US Food and Drug Administration (FDA) for patients with metastatic castrate-resistant prostate cancer (CRPC). OBJECTIVE To describe the real-world treatment patterns, healthcare costs, and survival rates of patients with metastatic CRPC and bone metastases who have commercial or Medicare coverage. METHODS This retrospective observational study was conducted using medical and pharmacy claims from the Humana research database for male patients who had Medicare or commercial coverage and were aged 55 to 89 years at the initiation of treatment for metastatic CRPC. Three inclusion criteria were used to identify appropriate patients for the 2 cohorts, including (1) a diagnosis of prostate cancer (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 185.x); (2) a diagnosis of bone metastasis (ICD-9-CM code 198.5) between 2013 and 2014; and (3) a healthcare insurance claim indicating a prescription for an FDA-approved first-line treatment for metastatic CRPC. Subsequent lines of treatment were also identified through the healthcare claims data. The 2-year survival rate was calculated and controlled for demographic and clinical characteristics, and the total costs (medical plus pharmacy) were calculated for the 6 months postindex. RESULTS A total of 1855 patients met the study inclusion criteria. Of these patients, 660 (35.6%) received at least 1 medication. The patient count by line of treatment was 660 (100%) who received first-line therapy, 380 (57.6%) who received second-line treatment, 204 (30.9%) who received third-line therapy, and 107 (16.2%) who received fourth-line therapy. The medication distribution by line of treatment (using first-, second-, third-, or fourth-line therapy for each drug) was abiraterone acetate (50.5%, 61.3%, 68.6%, 75.7%); enzalutamide (15.6%, 39.2%, 54.4%, 71.0%); sipuleucel-T (9.2%, 13.9%, 20.1%, 20.6%); radium-223 dichloride (1.7%, 2.6%, 7.4%, 13.1%); cabazitaxel (2.3%, 5.5%, 16.2%, 19.6%); and docetaxel (22.1%, 32.1%, 42.6%, 48.6%). The total monthly unadjusted healthcare costs for patients who received an FDA-approved treatment was much higher ($9435) than for patients with metastatic prostate cancer who did not receive an FDA-approved treatment ($5055), and the 2-year survival rate for patients who received an FDA-approved treatment was 57.1% (25th percentile, 250 days; 50th percentile, 541 days). CONCLUSIONS The most common first-line treatment for patients with commercial or Medicare coverage who had metastatic CRPC was abiraterone or enzalutamide. Hormone therapies used as monotherapy were the most frequently used treatment, and their concomitant administration with other treatments was the second most common treatment pattern. Additional clinical studies are needed to further elucidate the treatment sequencing for patients with metastatic CRPC.

Abstract
BACKGROUND With advancements in diagnostic techniques, oligometastatic prostate cancer is diagnosed in patients who were, in the past, considered to have localized disease. Moreover, evidence of the effectiveness of treatment intensification for this disease is increasing, focusing on primary tumors as well as metastatic lesions. Thus, we can delay the start of systemic palliative treatment and improve overall survival. Many questions remain unclear, such as the definition of oligometastasis disease, or which patients should be offered aggressive treatment. Data are limited and come from small retrospective studies but show conclusively the benefits of survival in targeted primary prostate and metastatic prostate cancer therapy with surgery or radiotherapy. Often, stereotactic radiotherapy is used in this indication, with minimal side effects. In retrospective studies, 3-5 metastatic lesions were generally accepted for definition of oligometastatic disease, but patient subgroups were heterogeneous. A recent study attempts to better define oligometastatic disease and find out the right degree of intensification of treatment. When and in which patient to use metastasis-targeted therapy and when the standard systemic treatment is already meaningful. It is already clear that selected patients benefit from targeted personalized treatment. PURPOSE The purpose of this review is to offer an update of the problem of oligometastatic prostate cancer. The article presents an overview of data from contemporary literature, modern possibilities of diagnostic imaging methods and treatment options of oligometastatic prostate cancer including surgery and radiotherapy. authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE recommendation for biomedical papers. Submitted: 8. 2. 2019 Accepted: 5. 3. 2019.

Abstract
Mineralocorticoid receptor (MR) signaling which is closely associated with hypertension plays important roles in resistance to antiandrogen therapy in prostate cancer. However, its impact on the prognosis in androgen-deprivation therapy (ADT) has not been elucidated. Then, we investigated the impact of genetic variation in MR and comorbidity with hypertension on the prognosis in ADT. This study included 182 Japanese patients with prostate cancer treated with ADT, whose comorbidity status with hypertension were available. The associations of MR polymorphism (rs5522) and comorbidity with hypertension with clinicopathological parameters as well as progression-free survival and overall survival were examined. Clinicopathological characteristics were comparable between genetic variation in MR. However, homozygous variant in MR was associated with shorter time to castration resistance (P = 0.014) and any-cause death (P = 0.024). In patients' background, presence of comorbidity with hypertension showed the trend with lower PSA level at diagnosis and lower biopsy Gleason score, as well as significant association with less incidence of N1. Comorbidity with hypertension was associated with longer time to castration resistance (P = 0.043) and any-cause death (P = 0.046), which was diminished on multivariate analysis including age, PSA level at diagnosis, biopsy Gleason score, clinical stage, and the modality of hormonal therapy. Genetic variation in MR (rs5522) and comorbidity with hypertension were significantly and potentially associated with prognosis when treated with ADT, respectively. This suggests that the individual intensity of MR signaling may be associated with resistance to ADT and a promising biomarker in ADT.

Abstract
Objectives To examine whether it is more efficacious to commence exercise medicine in men with prostate cancer at the onset of androgen‐deprivation therapy (ADT) rather than later on during treatment to preserve bone and soft‐tissue composition, as ADT results in adverse effects including: reduced bone mineral density (BMD), loss of muscle mass, and increased fat mass (FM). Patients and methods In all, 104 patients with prostate cancer, aged 48–84 years initiating ADT, were randomised to immediate exercise (IMEX, n = 54) or delayed exercise (DEL, n = 50) conditions. The former consisted of 6 months of supervised resistance/aerobic/impact exercise and the latter comprised 6 months of usual care followed by 6 months of the identical exercise programme. Regional and whole body BMD, lean mass (LM), whole body FM and trunk FM, and appendicular skeletal muscle (ASM) were assessed by dual X‐ray absorptiometry, and muscle density by peripheral quantitative computed tomography at baseline, and at 6 and 12 months. Results There was a significant time effect (P < 0.001) for whole body, spine and hip BMD with a progressive loss in the IMEX and DEL groups, although lumbar spine BMD was largely preserved in the IMEX group at 6 months compared with the DEL group (−0.4% vs −1.6%). LM, ASM, and muscle density were preserved in the IMEX group at 6 months, declined in the DEL group at 6 months (−1.4% to −2.5%) and then recovered at 12 months after training. FM and trunk FM increased (P < 0.001) over the 12‐month period in the IMEX (7.8% and 4.5%, respectively) and DEL groups (6.5% and 4.3%, respectively). Conclusions Commencing exercise at the onset of ADT preserves lumbar spine BMD, muscle mass, and muscle density. To avoid treatment‐related adverse musculoskeletal effects, exercise medicine should be prescribed and commenced at the onset of ADT.

Abstract
STUDY OBJECTIVE To examine the risks and compare the occurrences of major long-term side effects (sexual dysfunction, bone fractures, diabetes, cardiovascular morbidity, acute myocardial infarction [MI], and dementia) in patients with prostate cancer who received androgen-deprivation therapy (ADT) with those who did not. DESIGN Propensity score-matched retrospective cohort study using Medicare claims data. DATA SOURCE National Cancer Institute's Surveillance, Epidemiology, and End Results Program-Medicare linked database. PATIENTS A total of 201,797 patients 66 years or older who were diagnosed with any stage of prostate cancer between 1992 and 2009; of these, 94,528 patients received ADT; 107,269 patients did not. MEASUREMENTS AND MAIN RESULTS We identified receipt of ADT and number of claims for ADT, and ascertained the long-term treatment-related side effects that occurred during 19 years of follow-up, from 1992-2010, from Medicare claims data. Cox proportional hazards models were used to estimate the incidences and hazard ratios (HRs) of newly developed side effects. Among all potential long-term side effects, the risk of bone fractures was highest (HR 1.39, 95% confidence interval [CI] 1.35-1.43), followed by diabetes (HR 1.21, 95% CI 1.18-1.24), dementia (HR 1.16, 95% CI 1.13-1.20), coronary heart disease (HR 1.12, 95% CI 1.09-1.14), and acute MI (HR 1.11, 95% CI 1.08-1.15) in those who received ADT compared with those who did not. The HRs for bone fractures and diabetes increased steadily as the number of ADT doses increased, indicating a linear trend in the dose-response relationship. Compared with patients who received active surveillance, ADT was associated with a 12% increased risk of sexual dysfunction (HR 1.12, 95% CI 1.05-1.20). The HR for sexual dysfunction increased to 1.68 (95% CI 1.59-1.77) when ADT was combined with radiation therapy and to 3.54 (95% CI 3.26-3.85) when ADT was combined with radiation and surgery. CONCLUSION The results of this study demonstrated that in men with prostate cancer, receipt of ADT was associated with higher risks of bone fractures, diabetes, dementia, coronary heart disease, acute MI, and sexual dysfunction than in those who did not receive ADT.

Abstract
OBJECTIVES To investigate the association between lean mass (LM) and fat mass (FM) with fatigue and vitality before and after exercise in patients with prostate cancer already undergoing androgen-deprivation therapy (ADT). SUBJECTS AND METHODS Cross-sectional associations between LM and FM with fatigue and/or vitality measures were examined in 229 patients (aged 43-90 years). Prospective analysis was undertaken in 129 patients who underwent a supervised 3-6 months exercise programme (predominantly resistance + aerobic). Whole body and appendicular LM, and total and trunk FM were assessed by dual X-ray absorptiometry. Fatigue was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-30) and vitality using the Short Form-36. RESULTS Based on the EORTC QLQ-30, 19% of patients had clinically relevant fatigue. There was no association between LM and fatigue; however, total (P = 0.013), trunk (P = 0.015) and percentage (P = 0.008) FM were higher in fatigued than not fatigued patients, with total and trunk FM 5.0 and 2.6 kg higher, respectively. For quartiles of vitality, a similar pattern emerged for FM with those in the lowest quartile of vitality having the highest FM values (P = 0.014-0.034). In contrast, following supervised exercise, change in fatigue and vitality were associated with change in total LM (r = -0.182, P = 0.042 and r = 0.309, P = 0.001, respectively) but not FM. Patients fatigued at baseline but not fatigued following the exercise programme gained a median (interquartile range) of 2.1 (0.7-3.2) kg LM. CONCLUSION In patients with prostate cancer treated with ADT, body composition is associated with fatigue, with higher total and trunk FM in those with clinically relevant fatigue. However, following exercise those no longer fatigued had an accompanying substantial increase in LM. Modifying body composition, both LM and FM, in patients with prostate cancer may favourably alter cancer-related fatigue levels and should be a target of exercise medicine in this population.

Abstract
To review direct comparative studies of the gonadotrophin-releasing hormone (GnRH) agonists goserelin, triptorelin, and leuprorelin for the treatment of prostate cancer, and identify whether there are meaningful clinical differences between these agents. In June 2017, the following searches were performed independently by two reviewers in PubMed: (i) 'prostate cancer' and 'triptorelin' and 'leuprorelin', (ii) 'prostate cancer' and 'triptorelin' and 'goserelin', and (iii) 'prostate cancer' and 'goserelin' and 'leuprorelin', without time restriction. Duplicates were deleted. Relevant conference abstracts were also screened. A total of 16 direct comparative trials were identified: 12 reported on efficacy outcomes, four on safety/tolerability, and five on the convenience of administration/user perceptions. These studies are restricted in terms of patient numbers, formulations assessed, and endpoints measured; none were adequately powered for survival outcome measures. Studies reporting on efficacy endpoints did not show major differences in the ability of these GnRH agonists to reduce levels of testosterone or prostate-specific antigen. Some studies suggest differences in short- or long-term testosterone control, the rate of injection site adverse events, and patient/healthcare professional perceptions, but definitive conclusions cannot be drawn from the existing evidence. Few direct comparative trials of GnRH agonists have been conducted. Whilst GnRH agonists provide a similar castration effect, there is not enough evidence to show that GnRH agonists are equivalent.

Abstract
BACKGROUND/AIM To evaluate bone mineral density (BMD) in Japanese patients with prostate cancer (PCa) after administering androgen deprivation therapy (ADT) for 2 years. PATIENTS AND METHODS A total of 84 Japanese patients with PCa were enrolled in this study during the period 2008-2011. BMD was measured by dual energy X-ray absorptiometry, every 6 months. The fracture risk assessment tool (FRAX) score was calculated before starting ADT. We evaluated the change in BMD over a 2-year period and the relationship between this change, the FRAX score, and the estimated glomerular filtration rate (eGFR). RESULTS Compared to baseline, BMD decreased by 2.50% at 6 months after ADT, by 4.28% after 12 months, by 5.34% after 18 months, and by 6.16% after 2 years (all p<0.05). Multivariate analysis revealed that the eGFR, according to a threshold rate of 73.5 ml/min, was a significant factor in BMD. CONCLUSION Lumbar BMD in Japanese patients with PCa decreased by 4.28% at 1 year after ADT and by 6.16% after 2 years. We found a correlation between the decrease in BMD and the eGFR before initiating ADT, suggesting a small BMD reduction in patients with PCa who have good renal function.

Abstract
The skeletal system is of paramount importance in advanced stage prostate cancer (PCa) as it is the preferred site of metastasis. Complex mechanisms are employed sequentially by PCa cells to home to and colonize the bone. Bone-resident PCa cells then recruit osteoblasts (OBs), osteoclasts (OCs), and macrophages within the niche into entities that promote cancer cell growth and survival. Since PCa is heavily reliant on androgens for growth and survival, androgen-deprivation therapy (ADT) is the standard of care for advanced disease. Although it significantly improves survival rates, ADT detrimentally affects bone health and significantly increases the risk of fractures. Moreover, whereas the majority patients with advanced PCa respond favorably to androgen deprivation, most experience a relapse of the disease to a hormone-refractory form within 1-2 years of ADT. The tumor adapts to surviving under low testosterone conditions by selecting for mutations in the androgen receptor (AR) that constitutively activate it. Thus, AR signaling remains active in PCa cells and aids in its survival under low levels of circulating androgens and additionally allows the cancer cells to manipulate the bone microenvironment to fuel its growth. Hence, AR and its downstream effectors are attractive targets for therapeutic interventions against PCa. Ca2+/calmodulin-dependent protein kinase kinase 2 (CaMKK2), was recently identified as a key downstream target of AR in coordinating PCa cell growth, survival, and migration. Additionally, this multifunctional serine/threonine protein kinase is a critical mediator of bone remodeling and macrophage function, thus emerging as an attractive therapeutic target downstream of AR in controlling metastatic PCa and preventing ADT-induced bone loss. Here, we discuss the role played by AR-CaMKK2 signaling axis in PCa survival, metabolism, cell growth, and migration as well as the cell-intrinsic roles of CaMKK2 in OBs, OCs, and macrophages within the bone microenvironment.

Abstract
Background Oxidative stress mitigated by antioxidant enzymes is thought to be involved in the progression to castration-resistant prostate cancer (CRPC) during androgen-deprivation therapy (ADT). This study investigated the association between genetic variations in antioxidant enzymes and the efficacy of ADT as well as its biological background. Patients and methods The non-synonymous or promoter-locating polymorphisms of antioxidant enzymes were examined as well as the time to CRPC progression and overall survival in 104 and 92 patients treated with ADT for metastatic and non-metastatic prostate cancer, respectively. In addition, intracellular reactive oxygen species and expression levels of antioxidant enzymes were examined in castration-resistant and enzalutamide-resistant cells. Results In metastatic prostate cancer, the AG/GG allele in GSTM3 rs7483 and CT/TT allele in CAT rs564250 were associated with a significantly lower risk of progression to CRPC and all-cause death compared with homozygotes of the major AA allele (hazard ratio [HR]; [95% confidence interval (CI)], 0.55 [0.34-0.86], P = 0.0086) and CC allele (HR; [95% CI], 0.48 [0.24-0.88], P = 0.016), respectively. On multivariate analyses, only GSTM3 rs7483 was associated with significant progression risk (AG/GG versus AA; HR; [95% CI], 0.45 [0.25-0.79], P = 0.0047) even after Bonferroni adjustment. In non-metastatic prostate cancer, the AG/GG allele in GSTM3 rs7483 was associated with a significantly lower risk of progression to CRPC (HR; [95% CI], 0.35 [0.10-0.93], P = 0.034) and all-cause death (HR; [95% CI], 0.26 [0.041-0.96], P = 0.043) compared with the AA allele. Intracellular reactive oxygen species levels were increased, accompanied with augmented GSTM3 expression in both castration-resistant and enzalutamide-resistant cells. Conclusions Differential activity of antioxidant enzymes caused by the polymorphism in GSTM3 may contribute to resistance to hormonal therapy through oxidative stress. The GSTM3 rs7483 polymorphism may be a promising biomarker for prostate cancer patients treated with ADT.
