Prostate cancer is the most common cancer in men, and the second leading cause of cancer-related death in Western countries. Prostate cancer-related death occurs in patients with metastatic castration-resistant prostate cancer. Although several new drugs for castration-resistant prostate cancer have been approved, each of these has prolonged survival by just a few months. Consequently, new therapies are sorely needed. Recently, it has been recognized that immunotherapy is an effective treatment for prostate cancer patients...

Prostate cancer is the most common cancer and one of the leading causes for cancer deaths in men. One of the commonly used approaches to treat metastatic prostate cancer was via first generation non-steroidal anti-androgens (NSAA) namely flutamide, nilutamide, bicalutamide and topilutamide. Most of the prostate cancer patients who are initially responsive develop a most aggressive form of disease called castration-resistant prostate cancer (CRPC). Second generation NSAA receptor antagonists (enzalutamide, apalutamide and darolutamide) are emerging as additional new options to treat CRPC...

Cyclin-dependent kinase 9 (CDK9), a member of the cyclin-dependent protein kinase (CDK) family, is involved in transcriptional elongation of several target genes. CDK9 is ubiquitously expressed and has been shown to contribute to a variety of malignancies such as pancreatic, prostate and breast cancers. Here we report the development of a heterobifunctional small molecule proteolysis targeting chimera (PROTAC) capable of cereblon (CRBN) mediated proteasomal degradation of CDK9. In HCT116 cells, it selectively degrades CDK9 while sparing other CDK family members...

OBJECTIVE: The aim of this study was to evaluate the additional value of magnetic resonance imaging-targeted biopsy (MRI-TB) to standard transrectal ultrasound-guided biopsy (SB) for detection of clinically significant prostate cancer (PCa). An additional aim was to compare the biopsy results to MRI evaluation using a Likert scale. MATERIALS AND METHODS: Patients with newly diagnosed localized PCa (n = 53) by clinical routine SB were prospectively included. The majority of the patients were scheduled for curative therapy before enrollment...

None of the generally accepted theories on prostate cancer development can fully explain many distinguishing features of the disease, such as intratumoral heterogeneity, metastatic growth, drug resistance and tumor relapse. Prostate stem cells are a heterogeneous and small subpopulation of self-renewing cells which can actively proliferate in response to changes in the androgen level and give rise to all the cell lineages that build the prostate epithelium. According to the cancer stem cell hypothesis, prostate cancer could be a stem cell disease...

Prostate focal therapy offers men the opportunity to achieve oncological control while preserving sexual and urinary function. The prerequisites for successful focal therapy are to accurately identify, localize and completely ablate the clinically significant cancer(s) within the prostate. We aim to evaluate the evidence for current and upcoming technologies that could shape the future of prostate cancer focal therapy in the next five years. Areas Covered: Current literature on advances in patient selection using imaging, biopsy and biomarkers, ablation techniques and adjuvant treatments for focal therapy are summarized...

PURPOSE  : Temporal Enhanced Ultrasound (TeUS) has been proposed as a new paradigm for tissue characterization based on a sequence of ultrasound radio frequency (RF) data. We previously used TeUS to successfully address the problem of prostate cancer detection in the fusion biopsies. METHODS  : In this paper, we use TeUS to address the problem of grading prostate cancer in a clinical study of 197 biopsy cores from 132 patients. Our method involves capturing high-level latent features of TeUS with a deep learning approach followed by distribution learning to cluster aggressive cancer in a biopsy core...

This study investigated whether plasma selenium levels modified the risk for prostate cancer (PC) related to arsenic exposure. We conducted a case-control study that included 318 PC patients and 318 age-matched, healthy control subjects. Urinary arsenic profiles were examined using HPLC-HG-AAS and plasma selenium levels were measured by ICP-MS. We found that plasma selenium levels displayed a significant dose-dependent inverse association with PC. The odds ratio (OR) and 95% confidence interval (CI) for PC was 0...

DEP domain containing 1 (DEPDC1) is recently reported to be overexpressed in several types of human cancer; however the role of DEPDC1 in prostate cancer remains to be investigated. Herein, we identified that the DEPDC1 mRNA and protein expression levels were dramatically increased in prostate cancer tissues and cell lines. Overexpression of DEPDC1 promoted, but depletion of DEPDC1 inhibited cell proliferation by regulating the G1-S phase cell cycle transition. Importantly, we found that DEPDC1 was essential for the tumor growth and formation of bone metastases of prostate cancer cells in vivo...

Recent studies show that androgen-induced apoptosis in Atlantic croaker primary granulosa/theca (G/T) cells and in human breast and prostate cancer cell lines is mediated by the novel membrane androgen receptor ZIP9 which belongs to the SLC39A zinc transporter family. However, the apoptotic signaling pathways remain unclear because ZIP9 activates an inhibitory G protein in human cancer cells, whereas recombinant croaker ZIP9 activates a stimulatory G protein (Gs) in transfected cancer cells. Here we investigated androgen-dependent apoptotic pathways in order to identify the signaling pathways regulated through wild-type croaker ZIP9 in ovarian follicle cells...

Background: : Mutations in the androgen receptor (AR) ligand-binding domain (LBD), such as F877L and T878A, have been associated with resistance to next-generation AR-directed therapies. ARN-509-001 was a phase I/II study that evaluated apalutamide activity in castration-resistant prostate cancer (CRPC). Here we evaluated the type and frequency of 11 relevant AR-LBD mutations in apalutamide-treated CRPC patients. Patients and methods: : Blood samples from men with non-metastatic CRPC (nmCRPC) and metastatic CRPC (mCRPC) pre- or post abiraterone acetate and prednisone (AAP) treatment (≥6 months' exposure) were evaluated at baseline and disease progression in trial ARN-509-001...

The prevalence of TMPRSS2-ERG fusions in prostate cancer varies by race. However, such somatic aberration and its association with prognostic factors have neither been studied in a West African population nor been systematically reviewed in the context of racial differences. We used immunohistochemistry to assess ERG expression as the established surrogate of ERG fusion genes among 262 prostate cancer biopsies from the Ghana Prostate Study. Poisson regression with robust variance estimation provided prevalence ratios and 95% confidence intervals of ERG expression in relation to patients' characteristics...

A 74-year-old man with newly diagnosed prostate cancer underwent Ga-PSMA PET/CT, which demonstrated intense uptake in and adjacent the L2 vertebral body. Subsequent MRI of the lumbar spine showed an aggressive L2 hemangioma with adjacent soft tissue extension. There was congruence of the intraosseous and extraosseous components of the hemangioma and the PSMA PET uptake. This is a rare but important potential pitfall in Ga-PSMA PET/CT-a soft tissue lesion with intense tracer uptake related not to a nodal metastasis of prostate cancer but to extraosseous extension of an aggressive vertebral body hemangioma...

OBJECTIVES: Inclusion of 3-dimensional H magnetic resonance spectroscopic imaging (3D-H-MRSI) in routine multiparametric MRI of the prostate requires good quality spectra and easy interpretable metabolite maps of the whole organ obtained without endorectal coil in clinically feasible acquisition times. We evaluated if a semi-LASER pulse sequence with gradient offset independent adiabaticity refocusing pulses (GOIA-sLASER) for volume selection can meet these requirements. MATERIALS AND METHODS: Thirteen patients with suspicion of prostate cancer and 1 patient known to have prostate cancer were examined at 3 T with a multichannel body-receive coil...

PURPOSE OF REVIEW: To investigate the association between obesity and prostate cancer (PCa). RECENT FINDINGS: Obesity has been proposed to be involved in the pathogenesis of PCa through different biological mechanisms that include deregulation of the insulin axis, sex hormone secretion, adipokines signaling, and oxidative stress. Hypertrophic peritumoral adipocytes may also facilitate the local spread of PCa through the chemo-attraction of tumor cells. Clinical studies demonstrate that obesity might have clinical implications also in disease detection and management...

This review summarizes current evidence of the etiology and diagnosis of prostate cancer. As before, a comprehensive urological examination remains the main method of diagnosing the disease. However, the invasive nature of the multicore prostate biopsy, its high cost and the need for specially trained personnel prompts to seek more state-of-the-art and non-invasive methods for diagnosing prostate cancer. The further research in this direction seems promising.
