Comparison of staging using [Ga]Ga-PSMA-11 PET/CT and histopathological results in intermediate- and high-risk prostate cancer patients treated with radical prostatectomy and pelvic lymph node dissection.

Objective: To evaluate the diagnostic accuracy of [Ga]Ga-PSMA-11 PET/CT (PET-PSMA) in local and loco-regional nodal staging compared with histopathological results in intermediate- and high-risk prostate cancer patients treated with radical prostatectomy (RP) and pelvic lymph node dissection (PLND).

Materials Y Methods: A total of 122 intermediate- and high-risk prostate cancer (PCa) patients staged with PET-PSMA and treated with RP (36/122) and RP plus PLND (86/122) from December 2018 to December 2023 were included. Visual and semiquantitative analysis findings using the SUVmax of the molecular imaging were correlated with histopathological results.

An Unexpected Seminal Vesicle Pitfall in PSMA PET.

A 76-year-old man undergoing hormone therapy for prostate cancer was referred for 68 Ga-PSMA-11-PET (PSMA PET) due to persistently detectable PSA level. No PSMA-positive tumor lesions were detected, so a delayed phase imaging was performed, which revealed focal PSMA uptake in the right seminal vesicle together with contrast accumulation on excretory phase contrast-enhanced CT. These findings were finally determined to be secondary to urinary reflux as a consequence of a prostatic enucleation he had undergone 5 months earlier following an episode of acute urinary retention.

Incidental diagnosis of bladder cancer in a national observational study in spain.

Introduction: Bladder cancer (BC) is a common malignancy in Spain. The aims of this study were: to identify the proportion of patients diagnosed with BC incidentally or after symptomatic presentation in a contemporary period in Spain; to compare demographic, clinical, and pathologic characteristics between these groups.

Methods: This was a retrospective analysis of a multi-centre observational study of 26 hospitals in the Spanish National Health System of all BCs newly diagnosed in 2011.

Clinical feasibility of combining intraoperative electron radiation therapy with minimally invasive surgery: a potential for electron-FLASH clinical development.

Background: Local cancer therapy by combining real-time surgical exploration and resection with delivery of a single dose of high-energy electron irradiation entails a very precise and effective local therapeutic approach. Integrating the benefits from minimally invasive surgical techniques with the very precise delivery of intraoperative electron irradiation results in an efficient combined modality therapy.

Methods: Patients with locally advanced disease, who are candidates for laparoscopic and/or thoracoscopic surgery, received an integrated multimodal management.

Methods: This observational, retrospective, multicentre study included men ≥50 years of age diagnosed with LUTS/BPH (≤8 years prior to study visit) (N = 670). Therapeutic management according to healthcare service (primary care vs.

The role of prostate-specific antigen in light of new scientific evidence: An update in 2020.

Objective: To review and update the latest scientific evidence gathered in recent years regarding prostate-specific antigen (PSA) for better implementation into routine clinical practice.

Evidence Acquisition: Analysis of the available evidence on the current role of PSA, based on the experience of an expert panel in the subject under analysis.

Evidence Synthesis: Currently, PSA cannot be considered only as a guide for the presence or absence of prostate cancer.

Mutations primarily alter the inclusion of alternatively spliced exons.

Genetic analyses and systematic mutagenesis have revealed that synonymous, non-synonymous and intronic mutations frequently alter the inclusion levels of alternatively spliced exons, consistent with the concept that altered splicing might be a common mechanism by which mutations cause disease. However, most exons expressed in any cell are highly-included in mature mRNAs. Here, by performing deep mutagenesis of highly-included exons and by analysing the association between genome sequence variation and exon inclusion across the transcriptome, we report that mutations only very rarely alter the inclusion of highly-included exons.

Real-world assessment and characteristics of men with benign prostatic hyperplasia (BPH) in primary care and urology clinics in Spain.

Objectives: To describe the real-world demographic and clinical characteristics of patients with lower urinary tract symptoms (LUTS) as a result of benign prostatic hyperplasia (BPH) in Spain.

Methodology: This observational, retrospective, multicentre study conducted in primary care and urology clinics in Spain included men aged ≥50 years diagnosed (≤8 years prior to study visit) with LUTS caused by BPH. The primary endpoint was demographic and clinical characteristics; secondary endpoints included disease progression and diagnostic tests across both healthcare settings.

Androgen deprivation therapy in patients with localized disease: Comparison with curative intent treatments and time to castration resistance. Results of the Spanish Prostate Cancer Registry.

Background: The effect of primary androgen deprivation therapy (ADT) in patients with localized prostate cancer (PCa) has not been well documented. The objective of the present study was to analyze the outcome of tumors treated with ADT as primary therapy in the Spanish Prostate Cancer Registry (19.4% of the series).

Health questionnaire analysis and development of satisfaction questionnaire for patients treated with extracorporeal shock wave lithotripsy (SATISLIT).

Introduction: Due to the absence of specific instruments to study the psychosocial sphere of patients undergoing extracorporeal shock wave lithotripsy (SWL), the objective of this study is to develop a satisfaction questionnaire regarding the SWL treatment from a health questionnaire which was already designed and had been previously validated.

Material And Methods: The design of the satisfaction questionnaire was carried out in 5 phases, based on a previously validated health scale in patients treated with SWL (ESPTL), including a total cohort of 135 patients treated at our center who received a phone interview. Phase 1: descriptive analysis of the series and scores of the 8 items of ESPTL.

Functional Network Analysis Reveals the Relevance of SKIIP in the Regulation of Alternative Splicing by p38 SAPK.

Alternative splicing is a prevalent mechanism of gene regulation that is modulated in response to a wide range of extracellular stimuli. Stress-activated protein kinases (SAPKs) play a key role in controlling several steps of mRNA biogenesis. Here, we show that osmostress has an impact on the regulation of alternative splicing (AS), which is partly mediated through the action of p38 SAPK.

Identification of mutations associated with acquired resistance to sunitinib in renal cell cancer.

Sunitinib is one of the most widely used targeted therapeutics for renal cell carcinoma (RCC), but acquired resistance against targeted therapies remains a major clinical challenge. To dissect mechanisms of acquired resistance and unravel reliable predictive biomarkers for sunitinib in RCC, we sequenced the exons of 409 tumor-suppressor genes and oncogenes in paired tumor samples from an RCC patient, obtained at baseline and after development of acquired resistance to sunitinib. From newly arising mutations, we selected, using in silico prediction models, six predicted to be deleterious, located in G6PD, LRP1B, SETD2, TET2, SYNE1, and DCC.

Combinatorial Genetics Reveals a Scaling Law for the Effects of Mutations on Splicing.

Despite a wealth of molecular knowledge, quantitative laws for accurate prediction of biological phenomena remain rare. Alternative pre-mRNA splicing is an important regulated step in gene expression frequently perturbed in human disease. To understand the combined effects of mutations during evolution, we quantified the effects of all possible combinations of exonic mutations accumulated during the emergence of an alternatively spliced human exon.
