Role of Multiparametric Prostate Magnetic Resonance Imaging before Confirmatory Biopsy in Assessing the Risk of Prostate Cancer Progression during Active Surveillance.

Objective: To evaluate the impact of multiparametric magnetic resonance imaging (mpMRI) before confirmatory prostate biopsy in patients under active surveillance (AS).

Materials And Methods: This retrospective study included 170 patients with Gleason grade 6 prostate cancer initially enrolled in an AS program between 2011 and 2019. Prostate mpMRI was performed using a 1.

A Single-Center Experience With Third and Fourth Kidney Transplants and Second Kidney Transplant After Pancreas-Kidney Transplant: Surgical Aspects and Outcomes.

Objectives: Overall, 25% to 33% of patients on kidney transplant wait lists present with prior graft loss. In addition, the number of patients who require a retransplant seems to be increasing. Here, we describe our experience with patients who had a second kidney transplant after a previous pancreas-kidney transplant or a third or fourth kidney transplant.

Observational study comparing the accuracy/variability between the ERSPC and the PCPT risk calculators for the prediction of significant prostate cancer in patients with PSA <10 ng/mL.

Introduction: Risk calculators (RCs) are easy-to-use tools considering available clinical variables that could help to select those patients with risk of prostate cancer (PCa) who should undergo a prostate biopsy.

Objective: To perform a comparison for the prediction of significant PCa (SigPCa) between the European Randomised Study of Screening for PCa (ERSPC) and the PCa Prevention Trial (PCPT) RCs in patients with prostate-specific antigen (PSA) between 3 and 10 ng/mL through an evaluation of the accuracy/variability between two consecutive PSA values.

Setting: An observational study in a major university hospital in the south of Spain.

Oncogenic Role of Secreted Engrailed Homeobox 2 (EN2) in Prostate Cancer.

Engrailed variant-2 (EN2) has been suggested as a potential diagnostic biomarker; however, its presence and functional role in prostate cancer (PCa) cells is still controversial or unknown. Here, we analyzed 1) the expression/secretion profile of EN2 in five independent samples cohorts from PCa patients and controls (prostate tissues and/or urine) to determine its utility as a PCa biomarker; and 2) the functional role of EN2 in normal (RWPE1) and tumor (LNCaP/22Rv1/PC3) prostate cells to explore its potential value as therapeutic target. EN2 was overexpressed in our two cohorts of PCa tissues compared to control and in tumor cell lines compared with normal-like prostate cells.

CE-MS-based urinary biomarkers to distinguish non-significant from significant prostate cancer.

Background: Prostate cancer progresses slowly when present in low risk forms but can be lethal when it progresses to metastatic disease. A non-invasive test that can detect significant prostate cancer is needed to guide patient management.

Methods: Capillary electrophoresis/mass spectrometry has been employed to identify urinary peptides that may accurately detect significant prostate cancer.

Clinical association of metabolic syndrome, C-reactive protein and testosterone levels with clinically significant prostate cancer.

Recently, the influence that metabolic syndrome (MetS), hormonal alterations and inflammation might have on prostate cancer (PCa) risk has been a subject of controversial debate. Herein, we aimed to investigate the association between MetS-components, C-reactive protein (CRP) and testosterone levels, and the risk of clinically significant PCa (Sig-PCa) at the time of prostate biopsy. For that, men scheduled for transrectal ultrasound guided biopsy of the prostate were studied.

Plasma ghrelin O-acyltransferase (GOAT) enzyme levels: A novel non-invasive diagnosis tool for patients with significant prostate cancer.

Early detection of PCa faces severe limitations as PSA displays poor-specificity/sensitivity. As we recently demonstrated that plasma ghrelin O-acyltransferase (GOAT)-enzyme is significantly elevated in PCa-patients compared with healthy-controls, using a limited patients-cohort, we aimed to further explore the potential of GOAT to improve PCa diagnosis using an ample patients-cohort (n = 312) and defining subgroups (i.e.

New Approach to Guide Target Prostate Biopsy: Technique and Initial Experience.

Objective: To describe the technique of transrectal biopsy with a new device that fuses multiparametric magnetic resonance (mpMRI) and ultrasound images in real time to guide target biopsies and to evaluate our initial experience.

Methods: Patients with persistent suspicion of prostate cancer despite a previous negative biopsy and who had an mpMRI before the biopsy were selected. All patients underwent target biopsy plus standard systematic biopsy.

The oncogenic role of the spliced somatostatin receptor sst5TMD4 variant in prostate cancer.

sst5TMD4, a splice variant of the sst5 gene, is overexpressed and associated with aggressiveness in various endocrine-related tumors, but its presence, functional role, and mechanisms of actions in prostate cancer (PCa)-the most common cancer type in males-is completely unexplored. In this study, formalin-fixed, paraffin-embedded prostate pieces from patients with localized PCa, which included tumoral and nontumoral adjacent regions ( = 45), fresh biopsies from patients with high-risk PCa ( = 52), and healthy fresh prostates from cystoprostatectomies ( = 14) were examined. In addition, PCa cell lines and xenograft models were used to determine the presence and functional role of sst5TMD4.

European Randomized Study of Screening for Prostate Cancer Risk Calculator: External Validation, Variability, and Clinical Significance.

Objective: To externally validate the European Randomized Study of Screening for Prostate Cancer (ERSPC) risk calculator (RC) and to evaluate its variability between 2 consecutive prostate-specific antigen (PSA) values.

Materials And Methods: We prospectively catalogued 1021 consecutive patients before prostate biopsy for suspicion of prostate cancer (PCa). The risk of PCa and significant PCa (Gleason score ≥7) from 749 patients was calculated according to ERSPC-RC (digital rectal examination-based version 3 of 4) for 2 consecutive PSA tests per patient.

Ghrelin O-acyltransferase (GOAT) enzyme is overexpressed in prostate cancer, and its levels are associated with patient's metabolic status: Potential value as a non-invasive biomarker.

Ghrelin-O-acyltransferase (GOAT) is the key enzyme regulating ghrelin activity, and has been proposed as a potential therapeutic target for obesity/diabetes and as a biomarker in some endocrine-related cancers. However, GOAT presence and putative role in prostate-cancer (PCa) is largely unknown. Here, we demonstrate, for the first time, that GOAT is overexpressed (mRNA/protein-level) in prostatic tissues (n = 52) and plasma/urine-samples (n = 85) of PCa-patients, compared with matched controls [healthy prostate tissues (n = 12) and plasma/urine-samples from BMI-matched controls (n = 28), respectively].

Palliative surgery for rare cases of anterior urethral metastasis in prostate cancer.

Penis metastasis from prostate cancer is very rare, and its management varies from case to case as there are very few cases reported in the literature. We describe a patient with prostate cancer treated with radiotherapy and androgen deprivation therapy who presented with urethral bleeding as a symptom of anterior urethral metastasis during followup. We propose a way to manage this and review the literature.

[Current recommendations about the diagnosis and treatment of testosterone deficit syndrome: Clinical guidelines].

Testosterone deficit syndrome (TDS) is a clinical and biochemical syndrome associated with advanced age and characterized by some typical symptoms and decrease in serum testosterone levels, which can affect multiple organs and systems, deteriorating the quality of life of the males who suffer it. Due to the low specificity of the clinical picture, as well as that of the commonly used questionnaires, when there is a diagnostic suspicion, serum testosterone determination is necessary, without a current universally accepted determination method. The increased survival of males in the western world and their demand of a better quality of life,including the preservation of sexual activity, up to increasingly more advanced ages: together with the appearance of new ways of testosterone delivery, make this entity, clinical-biochemical, acquirean increasingly greater importance.
