Abstract Background: Some patients with prostate cancer have elevated gonadotropin levels. It is unknown, however, whether this condition directly influences carcinogenesis in the prostate. It is also unknown whether any specific hormone levels are useful to predict aggressive disease. The potential role of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) in prostate physiology is widely discussed. The study aimed to evaluate whether patients with this endocrine pattern have different outcomes following radical prostatectomy. Methods: This was a prospective cohort study of consecutive patients undergoing robot-assisted radical prostatectomy at the Andrology and Urology Department, National Medical Research… More >

Abstract Background: Minor bleeding after prostate biopsy is a relatively common complication, but clinically significant hemorrhage happens rarely. Management of prostatic artery pseudoaneurysm has not been described in the literature. Case Description: In this case, an 84-year-old man presented after prostate biopsy with rectal bleeding and required a massive transfusion. Ultimately, he was found to have a prostatic artery pseudoaneurysm, which to our knowledge is heretofore undescribed after prostate biopsy. Bleeding ultimately stopped spontaneously as the patient deferred angioembolization. He had not recurrent bleeding on follow up but is still deciding on treatment course for newly diagnosed More >

Abstract Stereotactic body radiotherapy (SBRT) for prostate cancer is a generally well-tolerated treatment but can rarely lead to complications such as fistula formation. We report a 69-year-old male on maintenance ibrutinib for chronic lymphocytic leukemia who developed a fistula between his bladder and vas deferens in the setting of ascending scrotal infection. Despite his prior history of SBRT, the fistula was successfully treated with minimally invasive measures. A combination of abscess debridement, urinary diversion, and broad-spectrum antibiotics helped to achieve fistula resolution. The unique presentation described herein highlights the importance of early aggressive intervention for source More >

Abstract Abiraterone acetate (ABTA) was approved by the USFDA in 2011 for treating metastatic castration-resistant prostate cancer (mCRPC). ABTA exhibits poor aqueous solubility, inadequate dissolution, low oral bioavailability (<10%), and significant positive food effects. To overcome these limitations, in the present work, ABTA solid dispersions (SDs) were developed by using hot melt extrusion technology (HME) with various grades of hydroxypropyl methylcellulose HME (HPMC HME 15LV and 100LV) at different extrusion temperatures. HPMC HME demonstrated the ability to prevent drug precipitation for up to 120 min compared to the free drug (10 min), sustaining the supersaturation state… More > Graphic Abstract

Abstract Objectives: This study aimed to develop an artificial intelligence (AI)-based image recognition system using the nnU-Net adaptive neural network to assist clinicians in detecting magnetic resonance imaging (MRI)-invisible prostate cancer. The motivation stems from the diagnostic challenges, especially when MRI findings are inconclusive (Prostate Imaging Reporting and Data System [PI-RADS] score ≤ 3). Methods: We retrospectively included 150 patients who underwent systematic prostate biopsy at Beijing Friendship Hospital between January 2013 and January 2023. All were pathologically confirmed to have clinically significant prostate cancer, despite negative findings on preoperative MRI. A total of 1475 MRI… More >

Abstract Overview: Freehand transperineal prostate biopsy (TPPB) needle guides are designed to maintain a parallel alignment between the co-axial introducer needle and the ultrasound (US) transducer. However, this parallel alignment necessitates transducer angulations within the patient’s rectum for sampling anterior or posterior regions of the prostate, which introduces several problems both for the patient and the operator. This article introduces a technique using a TPPB needle guide system with a novel angle-adjustment feature, which minimizes intrarectal transducer movements. Objectives: Freehand TPPB typically requires anterior or posterior angulation of the ultrasound (US) transducer, which leads to prostate More >

Abstract Objectives: The evidence remains insufficient and controversial for evaluating modifiable parameters—such as vitamin D, calcium, ferritin, and uric acid—as preclinical biomarkers to contribute to the prevention and early diagnosis of prostate cancer, a disease with a prevalence of up to 10%–20% in men over 50 and strongly associated with environmental factors including diet (high in fat and red meat), obesity, physical inactivity, and carcinogen exposure. This study aims to investigate the potential biomarker role of vitamin D, calcium, ferritin, and uric acids in reducing the risk of prostate cancer (PCa). Methods: The case-control design was… More >

Abstract Objectives: Treatment of patients with lower urinary tract symptoms (LUTS) is often challenging. In men, the origin of LUTS, in particular overactive bladder (OAB) symptoms, is often due to prostate enlargement. However, patients with chronic prostate inflammation (CPI) also frequently experience OAB. Thus far, it is not known if the inflammation per se or concomitant prostate enlargement is the underlying cause of LUTS. Currently, we aim to examine if there is any correlation between CPI and the persistence of OAB symptoms in patients with benign prostate hyperplasia (BPH). Methods: Fifty-one men underwent transurethral resection of… More >

Abstract Objective: The tumor microenvironment plays a pivotal role in prostate cancer progression and may differ across metastatic sites. This study aimed to evaluate and compare the primary and metastatic prostate adenocarcinoma tumor microenvironment. Methods: A total of 27 formalin-fixed paraffin-embedded tissue samples derived from 17 patients diagnosed with prostate adenocarcinoma, including the primary tumors, and the corresponding metastatic lymphatic and hematogenous lesions from various anatomical sites. Immunohistochemical labeling was performed using antibodies against Cluster of Differentiation 3 epsilon chain (CD3e), CD8 alpha chain (CD8a), Cluster of Differentiation 68 (CD68), Cluster of Differentiation 163 (CD163), Forkhead… More > Graphic Abstract
