Abstract
Prostate cancer (PCa) is a common malignancy in elderly men. We have applied Traditional Chinese Medicine CFF-1 in clinical treatments for PCa for several years. Here, we aimed to identify the underlying mechanism of CFF-1 on PCa using network pharmacology and experimental validation. Active ingredients, potential targets of CFF-1 were acquired from the public databases. Subsequently, protein-protein interaction (PPI) and the herbs-active ingredients-target network was constructed. A prognostic model for PCa was also constructed based on key targets. In vitro experiments using PCa cell lines CWR22Rv1 and PC-3 were carried out to validate the potential mechanism of CFF-1 on PCa. A total of 112 bioactive compounds and 359 key targets were screened from public databases. PPI and herbs-active ingredients-target network analysis determined 12 genes as the main targets of CFF-1 on PCa. Molecular docking studies indicated that the primary active ingredients of CFF-1 possess strong binding affinity to the top five hub targets. DNMT3B, RXRB and HPRT1 were found to be involved in immune regulation of PCa. In vitro, CFF-1 was found to inhibit PCa cell proliferation, migration, invasion and induce apoptosis via PI3K-Akt, HIF-1, TNF, EGFR-TKI resistance and PD-1 checkpoint signaling pathways. This study comprehensively elucidates the underlying molecular mechanism of CFF-1 against PCa, offering a strong rationale for clinical application of CFF-1 in PCa treatment.

Abstract
Recent therapeutic advances have led to increased survival times for patients with metastatic disease. Key to survival is early diagnosis and subsequent treatment as well as early detection of treatment failure allowing for therapy modifications. Conventional MR imaging techniques of the spine can be at times suboptimal for identifying viable tumor, as structural changes and imaging characteristics may not differ pretreatment and posttreatment. Advanced imaging techniques such as DCE-MRI can allow earlier and more accurate noninvasive assessment of viable disease by characterizing physiologic changes and tumor microvasculature.

Chromosomal Instability in Cell-free DNA as a Prognostic Biomarker of Metastatic Hormone-sensitive Prostate Cancer Treated with Androgen Deprivation Therapy. Eur Urol Focus 2023; 9:89-95. [PMID: 36167777 DOI: 10.1016/j.euf.2022.09.002] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Revised: 08/10/2022] [Accepted: 09/12/2022] [Indexed: 11/24/2022]
Abstract
BACKGROUND Although patients with metastatic hormone-sensitive prostate cancer (mHSPC) undergo androgen deprivation therapy (ADT), the disease can progress to metastatic castration-resistant prostate cancer (mCRPC). There are no reliable biomarkers for predicting this progression. Chromosomal instability resulting in copy number alterations (CNAs) is characteristically observed in patients with various cancers. OBJECTIVE To investigate the role of chromosomal instability in patients with mHSPC. DESIGN, SETTING, AND PARTICIPANTS This prospective study analyzed cell-free DNA (cfDNA) in pretreatment plasma samples from 75 patients with elevated prostate-specific antigen. Low-depth whole-genome sequencing of cfDNA was performed to identify CNAs. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS The I score (sum of the product of the absolute Z score and the corresponding chromosome length) was used as a measure of chromosomal instability. Kaplan-Meier and Cox proportional-hazard regression analyses were performed to evaluate the association between the I score and time to progression (TTP) and the prognostic value of chromosomal instability in predicting castration resistance, respectively. RESULTS AND LIMITATIONS Of 22 patients with a positive I score, 86.4% (19/22) had metastatic prostate cancer. Of these 19 cases, 94.7% (18/19) were mHSPC, which was high-volume mHSPC in 83.3% (15/18). None of the patients with localized prostate cancer had a positive I score. TTP in patients with mHSPC was significantly shorter in the positive than in the negative I-score group (16.4 vs 36.9 mo; p = 0.001). Only the I score could independently predict mCRPC development (hazard ratio 10.315, 95% confidence interval 1.141-93.208; p = 0.038). CONCLUSIONS The I score could be a biomarker for ADT response and progression to mCRPC in patients with mHSPC. PATIENT SUMMARY We investigated whether genetic changes in cell-free DNA can predict outcomes for patients with metastatic prostate cancer that still responds to hormone therapy. We found that chromosomal instability could be a potential predictor of the development of metastatic castration-resistant prostate cancer.

Abstract
AIM Prostate cancer (PCa) is the second most common nonskin malignancy and the second most common cause of cancer-related deaths in men. The most common site of metastasis in PCa is the axial skeleton which may lead to back pain or pathological fractures. Hematogenous spread to the brain and involvement of the central nervous system (CNS) are a rare occurrence. However, failed androgen deprivation therapy (ADT) may facilitate such a spread resulting in an advanced metastatic stage of PCa, which carries a poor prognosis. METHODS In this systematic review, we searched the PubMed, Scopus, and Web of Science online databases based on the PRISMA guideline and used all the medical subject headings (MeSH) in terms of the following search line: ("Brain Neoplasms" OR "Central Nervous System Neoplasms") and ("Prostatic Neoplasms" OR "Prostate"). Related studies were identified and reviewed. RESULTS A total of 59 eligible studies (902 patients) were included in this systematic review. In order to gain a deeper understanding, we extracted and presented the data from included articles based on clinical manifestations, diagnostic methods, therapeutic approaches, and prognostic status of PCa patients having BMs. CONCLUSION We have demonstrated the current knowledge regarding the mechanism, clinical manifestations, diagnostic methods, therapeutic approaches, and prognosis of BMs in PCa. These data shed more light on the way to help clinicians and physicians to understand, diagnose, and manage BMs in PCa patients better.

Abstract
Metastatic prostate cancer (mPCa) is one of the leading causes of cancer-related mortality in both the US and Europe. Androgen deprivation is the first-line therapy for mPCa; however, resistance to therapy inevitably occurs and the disease progresses to the castration resistant stage, which is uncurable. A definition of novel targeted therapies is necessary for the establishment of innovative and more effective protocols of personalized oncology. We employed genetically engineered mouse models of PCa and human samples to characterize the expression of the TRPM8 cation channel in both hormone naïve and castration resistant tumors. We show that Trpm8 expression marks both indolent (Pten-null) and aggressive (Pten/Trp53 double-null and TRAMP) mouse prostate adenocarcinomas. Importantly, both mouse and human castration-resistant PCa preserve TRPM8 protein expression. Finally, we tested the effect of TRPM8 agonist D-3263 administration in combination with enzalutamide or docetaxel on the viability of aggressive mouse PCa cell lines. Our data demonstrate that D-3263 substantially enhances the pro-apoptotic activity of enzalutamide and docetaxel in TRAMP-C1 e TRAMP-C2 PCa cell lines. To conclude, this study provides the basis for pre-clinical in vivo testing of TRPM8 targeting as a novel strategy to implement the efficacy of standard-of-care treatments for advanced PCa.

Abstract
Recently, studies on competing endogenous RNA (ceRNA) networks have become prevalent, and circular RNAs (circRNAs) have crucial implications for the development and progression of carcinoma. However, studies relevant to metastatic prostate cancer (mPCa) are scant. This study aims to discover potential ceRNAs that may be related to the prognosis of mPCa. RNA-Seq data were obtained from the MiOncoCirc database and Gene Expression Omnibus (GEO). Differential expression patterns of RNAs were examined using R packages. Circular RNA Interactome, miRTarBase, miRDB and TargetScan were applied to predict the corresponding relation between circRNAs, miRNAs and mRNAs. The Gene Ontology (GO) annotations were performed to present related GO terms, and Gene Set Enrichment Analysis (GSEA) tools were applied for pathway annotations. Moreover, survival analysis was conducted for the hub genes. We found 820 circRNAs, 81 miRNAs and 179 mRNAs that were distinguishingly expressed between primary prostate cancer (PCa) and mPCa samples. A ceRNA network including 45 circRNAs, 24 miRNAs and 56 mRNAs was constructed. In addition, the protein–protein interaction (PPI) network was built, and 10 hub genes were selected by using the CytoHubba application. Among the 10 hub genes, survival analysis showed that ITGA1, LMOD1, MYH11, MYLK, SORBS1 and TGFBR3 were significantly connected with disease-free survival (DFS). The circRNA-mediated ceRNA network provides potential prognostic biomarkers for metastatic prostate cancer.

Abstract
Prostate cancer (PCa), in particular, is known to cause significant psychosocial distress during the duration of a patient’s treatment due to its uncertainty and demasculinizing side effects. Prostate cancer support groups (PCSGs) have been proven to be beneficial, yet are underutilized by the majority of PCa patients and physicians. A thorough review of the literature was performed for articles pertaining to prostate cancer support groups. We sought to identify factors contributing to the psychological burden of the disease, factors that influenced patients to join, and barriers to participation in a PCSG. Additionally, the characteristics and format of PCSGs, as well as outcomes (i.e. quality of life), were evaluated.

Abstract
OBJECTIVES To investigate the recent real-world use of first-generation antiandrogens (FGAs) in metastatic castration-resistant prostate cancer (mCRPC) using a retrospective multicentre cohort study. PATIENTS AND METHODS The electronic CRPC Australian Database (ePAD) was interrogated to identify patients with mCRPC. Clinicopathological features, treatment and outcome data, stratified by FGA use, were retrieved and reported through descriptive statistics. Survival analyses were calculated using the Kaplan-Meier method and groups compared using log-rank tests. Factors influencing overall survival (OS) were analysed using Cox proportional hazards regression model. RESULTS We identified 634 patients with mCRPC, enrolled in ePAD between January 2016 and March 2019, including 322 (51%) who received FGAs. The median follow-up was 21.9 months. Patients treated with FGAs were more likely to have lower International Society of Urological Pathologists (ISUP) grade group (P = 0.04), longer median time to CRPC (25.6 vs 16.0 months, P < 0.001), and were less likely to have visceral metastases (5.0% vs 11.2%, P = 0.005) or to have received upfront docetaxel (P < 0.001). A ≥50% reduction from pre-treatment prostate-specific antigen (PSA) level (PSA50 response) during FGA treatment occurred in 119 (37%) patients and was independently associated with improved OS (hazard ratio 0.233, P < 0.001). Prior FGA treatment did not significantly influence the selection of subsequent life-prolonging treatments for mCRPC or their PSA50 response rates. CONCLUSION In our present cohort, FGAs were commonly used in lower-risk mCRPC and their use did not significantly influence the choice or duration of subsequent systemic therapy. A PSA50 response to FGA therapy was an independent favourable prognostic marker associated with improved OS.

Abstract
Background Patients with prostate cancer (PCa) commonly suffer from bone metastasis during disease progression. This study aims to construct and validate a nomogram to quantify bone metastasis risk in patients with PCa. Methods Clinicopathological data of patients diagnosed with PCa between 2010 and 2015 were retrospectively retrieved from the Surveillance, Epidemiology, and End Results (SEER) database. Predictors for bone metastasis were identified by logistic regression analyses to establish a nomogram. The concordance index (c-index) and calibration plots were generated to assess the nomogram’s discrimination, and the area under the receiver operating characteristic curve (AUC) was used to compare the precision of the nomogram with routine staging systems. The nomogram’s clinical performance was evaluated by decision curve analysis (DCA) and clinical impact curves (CIC). Independent prognostic factors were identified by Cox regression analysis. Results A total of 168,414 eligible cases were randomly assigned to the training cohort or validation cohort at a ratio of 1:1. The nomogram, which was established based on independent factors, showed good accuracy, with c-indexes of 0.911 in the training set and 0.910 in the validation set. Calibration plots also approached 45 degrees. After other distant metastatic sites were included in the predictive model, the new nomogram displayed superior prediction performance. The AUCs and net benefit of the nomograms were both higher than those of other routine staging systems. Furthermore, bone metastasis prediction points were shown to be a new risk factor for overall survival. Conclusions Novel validated nomograms can effectively predict the risk of bone metastasis in patients with PCa and help clinicians improve cancer management.

Abstract
Introduction The systemic therapies available to patients with metastatic prostate cancer (mPC) have improved dramatically over the past decade. Anecdotal experience suggests that the increased available lines of therapy have changed the profile of mPC to include a higher prevalence of visceral metastases. Materials and Methods A retrospective review of 472 patients with prostate cancer who died in 2009 and in 2016 was performed. Patients with metastatic disease who had imaging within six months of death were included. A total of 164 patients were eligible for analysis. Results Overall rates of visceral and distant metastases, including the lung, liver, adrenal, brain, renal, spleen, and thyroid, were higher in patients who died in 2016 as compared to those who died in 2009 (40.0% and 26.1%, respectively, p-value = 0.07). Forty-four percent of patients who died in 2016 used five or more lines of systemic treatments compared to 26.1% of patients in 2009. Conclusion The emergence of new systemic therapies for mPC is changing the natural history of the disease. Visceral metastases are being seen with increasing frequency than in the past. This observation is important for clinicians who are monitoring patients with prostate cancer to maintain a high suspicion for visceral disease.

Examining the Priorities, Needs and Preferences of Men with Metastatic Prostate Cancer in Designing a Personalised eHealth Exercise Intervention. Int J Behav Med 2020; 28:431-443. [PMID: 32968943 DOI: 10.1007/s12529-020-09932-2] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/14/2020] [Indexed: 12/31/2022]
Abstract
BACKGROUND Few individuals with metastatic prostate cancer have access to prostate cancer-specific exercise support, despite demonstrated benefits. eHealth tools, such as websites, may be viable options for increasing access. To be effective and acceptable, future eHealth websites need to consider end-users' perspectives, capacity and needs. We aim to provide insight into these factors by exploring daily priorities, activities and health literacy of individuals with metastatic prostate cancer and their perspectives towards exercise and exercise-based web-based eHealth interventions. METHODS Semi-structured interviews explored participant's experiences and understanding of their disease, exercise levels, advice received from health care providers, as well as acceptability of and suggested content for an eHealth tool. A thematic analysis was undertaken. RESULTS Interviews were conducted with eighteen Australians (55-83 years; M = 71.5, SD = 8.9) living with metastatic prostate cancer. Needing to perform daily responsibilities was a key priority. Participants had limited understanding of the benefits of prostate cancer-specific exercise, and less than half discussed exercise with their health team. Fourteen men felt they could report metastases location, but only four could provide detailed information, which has clinical implications for exercise prescription. A potential web-based intervention was considered acceptable by seventeen men for reasons such as affordability, accessibility and convenience. User-friendly design and practitioner support were important. CONCLUSIONS Results identified key aspects useful for person-centred design of exercise programs. Participants were positive towards the proposed web-based tool and expressed the need for individualised, user-friendly and reliable information with support from a professional embedded. Lastly, not all participants could accurately report metastasis locations.

Abstract
PURPOSE Reliable molecular diagnostic tools are still unavailable for making informed treatment decisions and monitoring the response in patients with castration resistant prostate cancer. We evaluated the significance of whole blood circulating androgen receptor transcripts of full length (AR-FL) and splice variants (AR-V1, AR-V3 and AR-V7) as biomarkers of abiraterone acetate treatment resistance in patients with castration resistant prostate cancer. MATERIALS AND METHODS After retrospective analysis in 112 prostate specimens AR-FL, AR-V1, AR-V3 and AR-V7 were evaluated in 185 serial blood samples, prospectively collected from 102 patients with castration resistant prostate cancer before and during abiraterone acetate therapy via reverse transcription quantitative polymerase chain reaction. RESULTS AR-FL was present in all samples while AR-V1, AR-V3, AR-V7 and at least 1 of them was detected in 17%, 55%, 65% and 81% of castration resistant prostate cancer blood samples, respectively. The highest amount of AR-V1 was found in blood of patients whose response time was short and medium in comparison to extended. Patients with a higher level of AR-FL and/or AR-V1 had the shortest progression-free survival and overall survival (p <0.0001). CONCLUSIONS Blood circulating AR-FL or AR-V1 can serve as blood based biomarkers for identification of the primary resistance to abiraterone acetate and the tool to monitor de novo resistance development during abiraterone acetate treatment.

Abstract
BACKGROUND Brain metastases from prostate cancer are rare and poorly described. We sought to assess the proportion of brain metastases arising from prostate cancer and to detail clinical characteristics, treatment modalities, and survival outcomes. METHODS We retrospectively identified and reviewed the charts of 31 patients with intraparenchymal brain metastases from prostate adenocarcinoma seen at our institution from 2008 to 2018. RESULTS Among all patients with brain metastases, the proportion originating from prostate adenocarcinoma was 0.86%. The median age at the time of brain metastasis diagnosis was 69 (range, 57-90). The median original Gleason score was 8 (range, 6-10), and the median prostate-specific antigen at the time of brain metastasis was 60 ng/mL (range, 0.34-4600). The median months from initial cancer diagnosis to brain metastasis was 81 (range, 3-195). The median number of brain metastases was 2 (range, 1-5). Patients had concurrent metastases to bone (100%), lung (48%), and liver (35%). Median overall survival was 3 months (range, 0.4-25.0). Treatment of the brain metastases was correlated with an increase in median survival from 1.2 months to 4.6 months with radiosurgery (hazard ratio = 0.11, P = 0.001) and surgical resection plus radiotherapy to 13 months (hazard ratio = 0.05, P < 0.001). All patients died of advanced, systemic disease and not of their intracranial disease. CONCLUSIONS Brain metastasis from prostate cancer constitutes a small fraction of total brain metastases, but is associated with poor prognosis and is seen in the setting of advanced, castrate resistant disease. These data enable treating physicians to appropriately counsel their patients with prostate adenocarcinoma brain metastasis.

Prevalence of Anxiety and Depression in Prostate Cancer Patients and Their Spouses: An Unaddressed Reality. Prostate Cancer 2020; 2020:4393175. [PMID: 32231798 PMCID: PMC7097760 DOI: 10.1155/2020/4393175] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2019] [Accepted: 10/17/2019] [Indexed: 01/07/2023] Open
Abstract
Objectives To estimate the prevalence of unsuspected anxiety or depression in prostate cancer patients and their spouses, as well as factors involved in its onset. Materials and Methods. A prospective study of 184 patients and 137 spouses evaluated in our hospital during 2019 using the Memorial Anxiety Scale for Prostate Cancer (MAX-PC), Hospital Anxiety and Depression Scale (HADS) and Patient Health Questionnaire depression module (PHQ-9). This study provides an internal validity assessment of the scales and their correlation (alpha and rho coefficients; index r). The contributions of age, education level, months after diagnosis, pain, prostate-specific antigen (PSA) level, stage of the disease and treatment performed to the positivity of the questionnaires were studied using the Wilcoxon–Mann–Whitney and chi-square tests. Results The prevalence of anxiety was 10.9% (MAX-PC) and 28.3% (MAX-PC-PSA). The HADS-A questionnaire indicated pathology in 14.1% of the patients and 16.05% of the spouses. Depression was detected in 7% (HADS-D) and 9.2% (PHQ-9) of patients as well as in 8.8% (HADS-D) and 16.05% (PHQ-9) of their spouses. The greatest concordance between men and women was with the PHQ-9 (Spearman's rho: 0.78; p = 0.01). Education level is significantly related to the presence of anxiety and depression, regardless of the questionnaire applied. The probability of detecting pathology in the MAX-PC varied from 6% in patients with elementary education to 23.5% in university students (p = 0.04). The greatest differences were detected when applying the PHQ-9 to patients (4% pathological, elementary education vs. 35.3% pathological, university education). Our study confirms the lack of a relationship between rates of anxiety and depression and factors such as PSA level, age of the patient and number of comorbidities. Conclusion There is a high prevalence of unsuspected anxiety and depression in patients with prostate cancer and their wives. Education level correlates with such prevalence.

Abstract
Androgen deprivation therapy as single modality therapy was the standard management for oligometastatic prostate cancer (PCa). Current paradigm shifts toward a multimodality therapy approach, targeting all sites of disease, including treatment of the primary in the form of radical prostatectomy or radiation therapy. The objective of this article was to reveiw the literature regarding the role of surgery in oligometastatic PCa. PubMed and MEDLINE electronic databases were queried for English language articles from January 1, 1980 to March 31, 2019. Keywords use included oligometastatic PCa, metastatic prostate cancer (mPCa), radical prostatectomy, and cytoreductive prostatectomy. Preclinical, prospective, and retrospective studies were included. There is no published randomized controlled trials, evaluating the role of surgery in mPCa. Preclinical and retrospective data suggest benefit of primary tumor treatment in mPCa. Current literature supports the concept of cytoreductive surgery as it can prevent late symptomatic local progression, has acceptable complications, and may prolong survival in patients with mPCa. Surgery is a feasible procedure in mPCa which may improve outcome in mPCa. However, there is no Level 1 evidence, yet that support the role of surgery in mPCa. The results from well-organized prospective, randomized controlled trials are awaited before performing radical prostatectomy for mPCa in clinical practice.

Abstract
The epidemiology of prostate cancer (PC) continues to change. We evaluated the changes in incidence, in average age at diagnosis, and in survival from 1992 to 2015 in Ontario. We compared the cumulative incidence of PC-specific and non PC-specific mortality using two algorithms for cause of death: Method 1 assigned deaths from "other cancers" to non PC-specific causes, and Method 2 assigned these cases to PC-specific mortality. There were 188,714 cases diagnosed with PC between 1992 and 2015 in Ontario. The average age at diagnosis declined from 1992 to 2008 by 0.26 year (3.1 months) annually (p < 0.001) and increased by 0.15 year (1.8 months) thereafter (p > 0.05). Between 2010 and 2015, the proportion of patients diagnosed at stage IV increased, and the proportion diagnosed at stage I decreased (p-values for trends <0.001). Overall survival significantly improved over the years. The cumulative incidence of PC-specific mortality at 5 and 10 years was 6.8 and 9.8% using Method 1, and 10.2 and 16.8% using Method 2. We observed trends toward older age and more advanced stage at PC diagnosis in Ontario. Further studies are needed to validate algorithms for estimating PC-specific mortality from administrative databases.

Abstract
BACKGROUND The CHAARTED and LATITUDE trials demonstrated improved outcomes with docetaxel or abiraterone plus androgen deprivation therapy in metastatic hormone sensitive prostate cancer (mHSPC) using two different prognostic scores. OBJECTIVE The aim of our study was to assess the concordance between the two scores and if these retained their prognostic value exclusively in de novo mHSPC. PATIENTS AND METHODS De novo mHSPC patients referring to our institution were retrospectively stratified according to the CHAARTED and LATITUDE classifications: high volume/high risk (HV/HR), low-volume/low-risk (LV/LR), and HVorHR (HV/LR and LV/HR). The Kaplan-Meier method and Cox proportional-hazard models were used to estimate hazard ratios for overall survival. RESULTS The study population included 106 patients. Concordance between the CHAARTED and LATITUDE classifications was observed in 86.8% of cases (65.1% HV/HR, 21.7% LV/LR), while 13.2% of patients fulfill the criteria of only one of the two classifications (HVorHR). When analyzed independently, the CHAARTED and LATITUDE classifications maintained their prognostic value (mOS 28.2 months in HV versus 60.9 months in LV, p = 0.006; 28.2 months in HR versus 40.6 months in LR, p = 0.017). The LR/LV population showed significantly longer mOS compared to the HR/HV group (72.6 months versus 26.3 months; p = 0.005), and to HVorHR patients (35.1 months; p = 0.003). No difference in OS was observed between HV/HR and HVorHR patients. ECOG PS ≥ 1 and patient age improved the prognostic value of the two classifications with multivariate analysis. CONCLUSIONS Our study showed a lack of complete concordance between the CHAARTED and LATITUDE classifications. The analysis confirmed the role of these prognostic scores to stratify de novo mHSPC patients in clinical practice.

Abstract
OBJECTIVES To estimate the prevalence of prostate cancer with bone metastasis in Beijing, and to estimate hospital visits and direct treatment costs among male urban employees with the disease in Beijing. DESIGN Cross-sectional observational study. SETTING AND PARTICIPANTS Patients with prostate cancer and bone metastasis from the Urban Employee Basic Medical Insurance database covering the employed population of Beijing, China, from 2011 to 2014. PRIMARY AND SECONDARY OUTCOME MEASURES Prevalence, treatment costs and healthcare visits of patients with prostate cancer and bone metastasis. RESULTS A total of 1672 individuals were identified as having prostate cancer. Of these, 737 (44.1%) had bone metastasis, and among these, this was already present at the time of initial prostate cancer diagnosis in 27.0% (199/737). Mean age was 74.6 years (SD ±9.1). Prevalence of prostate cancer with bone metastasis increased from 5.3 per 100 000 males in 2011 to 8.3 per 100 000 males in 2014. The total annual health expenditure per patient (in 2014 American dollars) during the study period was $15 772.1 (SD=$16 942.6) ~$18 206.3 (SD=$18 700.2); 88% of these costs were reimbursed by insurance. Medication accounted for around 50% of total healthcare costs. Western drugs accounted for over 80% of medical costs with endocrine therapy being the most commonly prescribed treatment. There was an average 6.7% increase in expenditure related to diagnostical and therapeutical procedures over study years. CONCLUSIONS The increase in the prevalence of prostate cancer with bone metastasis and associated healthcare costs in China reveals the growing clinical and economical burden of this disease. The high prevalence of bone metastasis among patients with prostate cancer seen in our study suggests that efforts may be needed to improve symptoms awareness and promote early help-seeking behaviour among the Chinese population.

Abstract
BACKGROUND Malignant diseases have become a threat for health care system. A panoply of biological processes is involved as the cause of these diseases. In order to unveil the mechanistic details of these diseased states, we analyzed protein families relevant to these diseases. RESULTS Our present study pivots around four apparently unrelated cancer types among which two are commonly occurring viz. Prostate Cancer, Breast Cancer and two relatively less frequent viz. Acute Lymphoblastic Leukemia and Lymphoma. Eight protein families were found to have implications for these cancer types. Our results strikingly reveal that some of the proteins with implications in the cancerous cellular states were showing the structural organization disparate from the signature of the family it constitutes. The sequences were further mapped onto respective structures and compared with the entropic profile. The structures reveal that entropic scores were able to reveal the inherent structural bias of these proteins with quantitative precision, otherwise unseen from other analysis. Subsequently, the betweenness centrality scoring of each residue from the structure network models was resorted to explore the changes in dependencies on residue owing to structural disorder. CONCLUSION These observations help to obtain the mechanistic changes resulting from the structural orchestration of protein structures. Finally, the hydropathy indexes were obtained to validate the sequence space observations using Shannon entropy and in-turn establishing the compatibility.

Abstract
Purpose: The spinal column is the most common location for osseous metastases and is associated with pain and decreased quality of life. This study evaluated combined radiofrequency ablation (RFA) with radiation therapy (RT) compared to RFA alone for improving pain and local control. Methods: This was a single-institution retrospective review of patients who underwent RFA of spinal metastases between 2016 and 2017, with or without RT to the same vertebral level. Pain was measured with visual analog scale at initial presentation and at 3 and 12 weeks of follow-up. Local failure (LF), distant failure, and overall survival (OS) were compared and Kaplan-Meier statistics were calculated. Results: Twenty-six patients with 28 spinal metastases were treated with RFA. Ten patients with 11 metastases were treated with RFA + RT. More patients with lung primaries were treated with RFA alone and more patients with breast primaries were treated with combination RFA+RT. There was no significant difference in pain scores between groups ( P = .96). At a median follow-up of 8.2 months, LF was noted in 8 of 17 metastases treated with RFA alone compared to 1 of 11 metastases treated with RFA+RT ( P = .049). There was a significant benefit in time to LF favoring RFA+RT ( P = .02) and a significant benefit in OS ( P = .0045). Conclusion: This study demonstrates a benefit in local control with RFA+RT versus RFA alone. Palliation of pain was effective using both regimens. This study was limited by a nearly unequal distribution of primary tumor histologies between groups. Literature regarding combined treatment of RFA and RT for spinal metastases is scarce and prospective protocols are warranted.

Abstract
In recent years, therapeutic advances, together with new medication sequences and combinations, have improved outcomes for prostate cancer. For a long time, androgen deprivation therapy (ADT) has been the standard of care for newly diagnosed, metastatic prostate cancer, first as a standalone therapy and then in combination with taxane-based regimens. More recently, the addition of abiraterone acetate to ADT to achieve complete androgen blockade has proven beneficial for the treatment of metastatic hormone-resistant prostate cancer and metastatic hormone-sensitive prostate cancer (mHSPC). In this review, we summarize recent findings on the early use of abiraterone in mHSPC and discuss survival benefits as reported in clinical trials. On the basis of existing data, abiraterone in combination with ADT could be considered a new standard of care for patients affected by mHSPC.

Abstract
Purpose Using the Surveillance, Epidemiology, and End Results database (SEER) to assess the incidence and risk factors of morbidity and prognosis for bone metastases in initial metastatic prostate cancer. Patients and methods The records of 249,331 prostate cancer patients in the SEER database, diagnosed between 2010 and 2014, were obtained were obtained to investigate the risk factors for developing bone metastasis, and the records of 9925 of them who registered before 2013 were retrieved (with at least 1 year follow up) to explore the prognostic factors for bone metastasis. Multivariate logistic and Cox regression were used to identify risk factors and prognostic factors for bone metastases, respectively. Results In total, 12,794 patients (5.1%) were diagnosed with bone metastases at the initial diagnosis. Older age, unmarried status, lymph node metastasis, poor tumor differentiation grade (Gleason grade), metastases at lung, brain, and liver were all positively associated with risk for the morbidity and prognosis of bone metastasis in prostate cancer. Black race and higher T stage were positively associated with bone metastasis development; however, they were not associated with a prognosis of bone metastasis. Conclusion The incidence of bone metastasis in prostate cancer was approximately 5% with poor survival. The prostate cancer has homogeneous and heterogeneous risk factors for incidence and prognosis of bone metastasis, which may provide potential guidelines for the screening and preventive treatment for the bone metastasis of prostate cancer.

Abstract
BACKGROUND Cancer care and end-of-life (EOL) care contribute substantially to health care expenditures. Outside of clinical trials, to our knowledge there exists no standardized protocol to monitor disease progression in men with metastatic prostate cancer (mPCa). The objective of the current study was to evaluate the factors and outcomes associated with increased imaging and serum prostate-specific antigen use in men with mPCa. METHODS Using Surveillance, Epidemiology, and End Results-Medicare data from 2004 to 2012, the authors identified men diagnosed with mPCa with at least 6 months of follow-up. Extreme users were classified as those who had either received prostate-specific antigen testing greater than once per month, or who underwent cross-sectional imaging or bone scan more frequently than every 2 months over a 6-month period. Associations between extreme use and survival outcomes, costs, and quality of care at EOL, as measured by timing of hospice referral, frequency of emergency department visits, length of stay, and intensive care unit or hospital admissions, were examined. RESULTS Overall, a total of 3026 men with mPCa were identified, 791 of whom (26%) were defined as extreme users. Extreme users were more commonly young, white/non-Hispanic, married, higher earning, and more educated (P<.001, respectively). Extreme use was not associated with improved quality of care at EOL. Yearly health care costs after diagnosis were 36.4% higher among extreme users (95% confidence interval, 27.4%-45.3%; P<.001). CONCLUSIONS Increased monitoring among men with mPCa significantly increases health care costs, without a definitive improvement in survival nor quality of care at EOL noted. Monitoring for disease progression outside of clinical trials should be reserved for those in whom findings will change management. Cancer 2018;124:2212-9. © 2018 American Cancer Society.

Abstract
PURPOSE OF REVIEW Summarizes recent advances in the treatment of metastatic castration-sensitive and castration-resistant prostate cancer. RECENT FINDINGS New randomized data suggest a survival advantage to early abiraterone in castration-sensitive metastatic prostate cancer. Prospective and retrospective studies are examining sequencing of existing cytotoxic and androgen-receptor-targeted therapies in both castration-sensitive and castration-resistant disease. Genomic analysis of both circulating tumor cells and circulating tumor nucleic acids is being examined as a potential method for selecting existing therapies and identifying novel therapeutic targets. Finally, immunotherapy combinations are being evaluated in the setting of advanced prostate cancer. SUMMARY In this review, we hope to summarize the recent data supporting the use of early abiraterone in castration-sensitive metastatic prostate cancer and discuss how this data might be incorporated with previous trials showing a survival advantage to early docetaxel. We present recent series examining sequencing of approved therapies as well as trials evaluating novel biomarkers and genomic analyses designed to help choose from among approved therapies or evaluate drugs in development. Lastly, we review ongoing trials examining novel immunotherapy combinations in advanced prostate cancer.

Does T1- and diffusion-weighted magnetic resonance imaging give value-added than bone scintigraphy in the follow-up of vertebral metastasis of prostate cancer? Investig Clin Urol 2017; 58:324-330.

Abstract
PURPOSE To evaluate the effectiveness of limited Magnetic Resonance (MR) images including T1- and diffusion-weighted image (DWI) for monitoring vertebral metastasis in patients with prostate cancer. MATERIALS AND METHODS From July 2014 to November 2016, patients diagnosed with spinal metastasis from prostate cancer using 99mTc bone scintigraphy were enrolled. Regardless of the primary local therapy, the changes in spinal metastasis were followed up using bone scan and biparametric MR (T1+DWI). All tests were followed up for more than 3 months. RESULTS Among the 14 follow-ups of 10 patients, 6 and 10 (including all progressed cases on bone scan) follow-ups were determined to show progressive disease using bone scan and biparametric MR, respectively. Otherwise, we could have predicted neurologic sequela earlier using biparametric MR. Examination time for biparametric MR was 15 minutes, and it was 4 hours for bone scan, respectively. CONCLUSIONS Although bone scan has been considered the standard test for bony metastasis in men with prostate cancer, limited MR including T1 and DWI has an additional benefit in monitoring spinal metastasis in patients who are already diagnosed as having spinal metastasis. The limited MR is more sensitive in detecting progressive disease. In addition, it can reduce neurologic complications caused by spinal metastasis.

Abstract
INTRODUCTION Cancer-induced bone pain (CIBP) is the most common type of pain with cancer. In humans, this pain can be difficult to control and highly disabling. A major problem with CIBP in humans is that it increases on weight-bearing and/or movement of a tumor-bearing bone limiting the activity and functional status of the patient. Currently, there is less data concerning whether similar negative changes in activity occur in rodent models of CIBP. OBJECTIVES To determine whether there are marked changes in activity in a rodent model of CIBP and compare this to changes in skin hypersensitivity. METHODS Osteosarcoma cells were injected and confined to 1 femur of the adult male mouse. Every 7 days, spontaneous horizontal and vertical activities were assessed over a 20-hour day and night period using automated activity boxes. Mechanical hypersensitivity of the hind paw skin was assessed using von Frey testing. RESULTS As the tumor cells grew within the femur, there was a significant decline in horizontal and vertical activity during the times of the day/night when the mice are normally most active. Mice also developed significant hypersensitivity in the skin of the hind paw in the tumor-bearing limb. CONCLUSION Even when the tumor is confined to a single load-bearing bone, CIBP drives a significant loss of activity, which increases with disease progression. Understanding the mechanisms that drive this reduction in activity may allow the development of therapies that allow CIBP patients to better maintain their activity and functional status.
