BACKGROUND: Metabolic syndrome (MetS) and prostate cancer (PCa) are highly prevalent conditions worldwide. Current evidence suggests the emerging hypothesis that MetS could play a role in the development and progression of several neoplasms. The aims of this study are to evaluate the impact of MetS and MetS factors on PCa incidence, on the risk of high-grade PCa and to analyze the role of MetS and single MetS components on the development of aggressive PCa features. METHODS: A systematic literature search and analysis on PubMed, EMBASE, Cochrane and Academic One File databases until September 2015 was performed by 2 independent reviewers to evaluate the associations between MetS and PCa incidence, and between MetS and high-grade PCa incidence (bioptical Gleason Score⩾8, Prognostic Group 4-5 according to the novel prostate cancer grading system)...

BACKGROUND: The Prostate Cancer Prevention Trial Risk Calculator 2.0 (PCPTRC) is a widely used risk-based calculator used to assess a man's risk of prostate cancer (PCa) before biopsy. This risk calculator was created from data of a patient cohort undergoing a 6-core sextant biopsy, and subsequently validated in men undergoing 12-core systematic biopsy (SBx). The accuracy of the PCPTRC has not been studied in patients undergoing magnetic resonance imaging/ultrasound (MRI/US) fusion-guided biopsy (FBx)...

In contrast to typical prostatic ductal adenocarcinoma, prostatic intraepithelial neoplasia (PIN)-like ductal adenocarcinoma is a rare variant of prostate cancer with low-grade clinical behavior. We report a case of a 66-year-old African-American male with an elevated serum prostate-specific antigen who underwent multiparametric prostate magnetic resonance imaging (MRI) and MRI/ultrasound fusion-guided biopsies. Pathology demonstrated low-volume Gleason score 3 + 3 = 6 (Grade Group 1), acinar adenocarcinoma involving one core and PIN-like ductal adenocarcinoma on a separate core...

BACKGROUND: The prostate-specific antigen (PSA) test is used to screen for prostate cancer but has a high false-positive rate that translates into unnecessary prostate biopsies and overdiagnosis of low-risk prostate cancers. We aimed to develop and validate a model to identify high-risk prostate cancer (with a Gleason score of at least 7) with better test characteristics than that provided by PSA screening alone. METHODS: The Stockholm 3 (STHLM3) study is a prospective, population-based, paired, screen-positive, diagnostic study of men without prostate cancer aged 50 to 69 years randomly invited by date of birth from the Swedish Population Register kept by the Swedish Tax Agency...

PURPOSE: Abnormal spindle microtubule assembly (ASPM) gene was known to be linked with poor clinical prognosis in various tumors. However, the clinical significance of ASPM in prostate cancer (PCa) has not yet been understood. The purpose of this study was to determine the association of ASPM with tumor progression and prognosis in PCa patients. METHODS: The expression of ASPM at protein level in human PCa and non-cancerous prostate tissue was detected by immunohistochemical analysis, which was further validated by using microarray-based dataset (NCBI GEO: GSE21032 and The Cancer Genome Atlas (TCGA) dataset) at mRNA level...

Extracellular vesicles (EVs) are microvesicles secreted from various cell types. We aimed to discover a new biomarker for high Gleason score (GS) prostate cancer (PCa) in urinary EVs via quantitative proteomics. EVs were isolated from urine after massage from 18 men (negative biopsy [n = 6], GS 6 PCa [n = 6], or GS 8-9 PCa [n = 6]). EV proteins were labeled with iTRAQ and analyzed by LC-MS/MS. We identified 4710 proteins and quantified 3528 proteins in the urinary EVs. Eleven proteins increased in patients with PCa compared to those with negative biopsy (ratio >1...

OBJECTIVES: To develop and externally validate a predictive model for detection of significant prostate cancer (PC). SUBJECTS AND METHODS: Development of the model was based on prospective cohort including 393 men who underwent mpMRI prior to biopsy. External validity of the model was then examined retrospectively in 198 men from a separate institution whom underwent a mpMRI followed by biopsy for abnormal PSA/DRE. A model was developed with age, PSA, DRE, prostate volume, previous biopsy and PIRADS score as predictors for significant PC (Gleason 7 with >5% grade 4, ≥ 20% cores positive or ≥ 7mm of PC in any core)...

BACKGROUND: The prognosis for patients with high-risk prostate cancer is poor. No consensus exists on the most effective treatment. The aim of this retrospective study was to identify the biochemical progression-free survival and the toxicity profile of patients with localized high-risk prostate cancer treated with external beam radiation therapy. These results will constitute a benchmark for a prospective "mixed beam" trial: a boost with carbon ions followed by a pelvic photon intensity-modulated radiotherapy (NCT02672449 [clinicaltrials...

OBJECTIVE: Prior studies in prostate diffusion-weighted magnetic resonance imaging (MRI) have largely explored the impact of b-value and diffusion directions on estimated diffusion coefficient D. Here we suggest varying diffusion time, t, to study time-dependent D(t) in prostate cancer, thereby adding an extra dimension in the development of prostate cancer biomarkers. METHODS: Thirty-eight patients with peripheral zone prostate cancer underwent 3-T MRI using an external-array coil and a diffusion-weighted image sequence acquired for b = 0, as well as along 12 noncollinear gradient directions for b = 500 s/mm using stimulated echo acquisition mode (STEAM) diffusion tensor imaging (DTI)...

Although the FAM84B gene lies within chromosome 8q24, a locus frequently altered in prostate cancer (PC), its alteration during prostate tumorigenesis has not been well studied. We report here FAM84B upregulation in DU145 cell-derived prostate cancer stem-like cells (PCSLCs) and DU145 cell-produced lung metastases compared to subcutaneous xenograft tumors. FAM84B protein was detected in bone metastases and primary PCs. Nanostring examination of 7 pairs of tumor adjacent normal and PC tissues revealed elevations in FAM84B mRNA levels in all carcinomas...
