INTRODUCTION: Prostate cancer is the most common malignant disease in men. The number of cases of prostate cancer has increased dramatically in recent 20 years. Radical prostatectomy is a surgical method for the first-line treatment of localised prostate cancer. We performed the first robotic-assisted radical prostatectomy on December 16th, 2005, achieved the boundary of 1000 robotic-assisted radical prostatectomies in 2012, and in 2015, we successfully completed the 1500th robotic-assisted operation on the prostate...

Complex genomic rearrangements are common molecular events driving prostate carcinogenesis. Clinical significance, however, has yet to be fully elucidated. Detecting the full range and subtypes of large structural variants (SVs), greater than one kilobase in length, is challenging using clinically feasible next generation sequencing (NGS) technologies. Next generation mapping (NGM) is a new technology that allows for the interrogation of megabase length DNA molecules outside the detection range of single-base resolution NGS...

BACKGROUND: In patients with prostate cancer (PCa), the lack of clear guidelines on the use of radiotherapy after radical prostatectomy (RP) invites unwanted variation of this treatment. We describe the hazard ratios and probabilities related to the use of post-RP radiotherapy. MATERIAL AND METHODS: Data were collected from the Cancer Registry of Norway and nine radiotherapy units. All patients were diagnosed with a non-metastatic PCa from January 2004 through June 2011...

Purpose: Korean patients with prostate cancer (PC) typically present with a more aggressive disease than patients in Western populations. Consequently, it is unclear if the current criteria for active surveillance (AS) can safely be applied to Korean patients. Therefore, this study was conducted to define appropriate selection criteria for AS for patients with PC in Korea. Materials and Methods: We conducted a multicenter retrospective study of 2126 patients with low risk PC who actually underwent radical prostatectomy...

Prostate Specific Antigen (PSA) is the most commonly used serum marker for prostate cancer (PCa), although it is not specific and sensitive enough to allow the differential diagnosis of the more aggressive tumors. For that, new diagnostic methods are being developed, such as PCA-3, PSA isoforms that have resulted in the 4K score or the Prostate Health Index (PHI), and PSA glycoforms. In the present study, we have compared the PHI with our recently developed PSA glycoform assay, based on the determination of the α2,3-sialic acid percentage of serum PSA (% α2,3-SA), in a cohort of 79 patients, which include 50 PCa of different grades and 29 benign prostate hyperplasia (BPH) patients...

OBJECTIVE: To investigate if curative prostate cancer (PCa) treatment was received less often by men with both PCa and Type 2 diabetes mellitus (T2DM), as little is known about if a diagnosis of T2DM influences receipt of curative treatment in men with localised PCa. SUBJECTS/PATIENTS AND METHODS: Data from Prostate Cancer database Sweden (PCBaSe) from men with T2DM and PCa (n=2,210) was used to compare with those with PCa only (n=23,071). All men had intermediate (T1-2, Gleason score 7 and/or PSA 10-20 ng/ml) or high risk (T3 and/or Gleason score 8-10 and/or PSA 20-50 ng/ml) localised PCa diagnosed between 1(st) January 2006 and 31(st) December 2014...

PURPOSE/BACKGROUND: [(18)F]fluoroethylcholine ((18)FECH) has been shown to be a valuable PET-tracer in recurrent prostate cancer (PCa), but still has limited accuracy. RM2 is a gastrin-releasing peptide receptor (GRPr) antagonist that binds to GRPr on PCa cells. Recent studies suggest that GRPr imaging with PET/CT is a promising technique for staging and restaging of PCa. We explore the value of GRPr-PET using the (68)Ga-labeled GRPr antagonist RM2 in a selected population of patients with biochemically recurrent PCa and a negative/inconclusive (18)FECH-PET/CT...

INTRODUCTION: Prostate cancer is the most prevalent malignant neoplasia among men worldwide. Several prognostic factors, including Gleason's score, the measurement of serum prostate-specific antigen (PSA) and the evaluation of the percentage of fragments affected by cancer on prostate biopsy, have already been established. Age alone, however, has yet to be studied as a prognostic factor independently from other known factors. The aim of the present study was to compare the characteristics and the evolution of prostate cancer in different age groups using a paired analysis for patients with equivalent known prognostic factors...

BACKGROUND: The use of prostate cancer screening tools that take into account relevant prebiopsy information (ie, risk calculators) is recommended as a way of determining the risk of cancer and the subsequent need for a prostate biopsy. This has the potential to limit prostate cancer overdiagnosis and subsequent overtreatment. mHealth apps are gaining traction in urological practice and are used by both practitioners and patients for a variety of purposes. OBJECTIVE: The impetus of the study was to design, develop, and assess a smartphone app for prostate cancer screening, based on the Rotterdam Prostate Cancer Risk Calculator (RPCRC)...

BACKGROUND: H3K27me3 histone marks shape the inhibition of gene transcription. In prostate cancer, the deregulation of H3K27me3 marks might play a role in prostate tumor progression. METHODS: We investigated genome-wide H3K27me3 histone methylation profile using chromatin immunoprecipitation (ChIP) and 2X400K promoter microarrays to identify differentially-enriched regions in biopsy samples from prostate cancer patients. H3K27me3 marks were assessed in 34 prostate tumors: 11 with Gleason score > 7 (GS > 7), 10 with Gleason score ≤ 7 (GS ≤ 7), and 13 morphologically normal prostate samples...
