The amino acid sequence of human prostate-specific antigen (APS) suggests that it is a member of the glandular kallikrein subfamily of serine proteases. In the mouse, the kallikrein-like family is localized in a single locus on chromosome 7, while other serine proteases are distributed over a variety of different chromosomes. To investigate the physical relationship between the human kallikrein genes, we have used in situ hybridization and Southern analysis of a human x mouse somatic cell hybrid panel to map the APS gene to 19q13, concordant with the renal kallikrein KLK1 gene. This finding indicates that APS is a member of a human kallikrein-like gene family with analogous organization to that of the mouse.

Therapeutic Challenges in Metastatic Castration-Resistant Prostate Cancer: A Case Study and Review of Prostate-Specific Membrane Antigen-Targeted Therapy Failures in Highly Prostate-Specific Membrane Antigen-Avid Disease.

Prostate cancer (PCa) is a leading cause of cancer-related deaths globally, with metastatic castration-resistant prostate cancer (mCRPC) posing significant treatment challenges. This case report discusses a 65-year-old male with mCRPC who initially responded to hormonal therapy but later showed disease progression despite additional chemotherapy. He subsequently received Lu-PSMA and Ac-PSMA therapies, both of which failed to halt disease progression despite having an intense PSMA avid metastatic disease.

Background: Current approach to clinically suspicious biopsy-naïve men consists performing prostate MRI, followed by combined systematic (TRUS-Bx) and MRI-Ultrasound fusion biopsy (MRI-TBx) in those with PIRADS score ≥ 3. Researchers have attempted to determine who benefits from each biopsy method, but the results do not support the safe use of one method alone. This study aims to determine the optimal approach in biopsy-naïve men, according to their PSA levels.

Background: PSMA PET/CT emerges as a pivotal technology in the diagnostic landscape of prostate cancer (PCa). It offers a suite of imaging interpretation criteria, notably the maximum standardized uptake value (SUVmax), the molecular imaging prostate-specific membrane antigen score (miPSMA score), and the PSMA reporting and data system (PSMA-RADS). Identifying the most valuable criteria for diagnosing PCa and standardizing imaging interpretation across various tracers is an unresolved question.

To develop and validate biopsy-free nomograms to more accurately predict clinically significant prostate cancer (csPCa) in biopsy-naïve men with prostate imaging reporting and data system (PI-RADS) ≥ 4 lesions. A cohort of 931 patients with PI-RADS ≥ 4 lesions, undergoing prostate biopsies or radical prostatectomy from January 2020 to August 2023, was analyzed. Various clinical variables, including age, prostate-specific antigen (PSA) levels, prostate volume (PV), PSA density (PSAD), prostate health index (PHI), and maximum standardized uptake values (SUVmax) from PSMA PET-CT imaging, were assessed for predicting csPCa.

Background: Metastatic castration-resistant prostate cancer (mCRPC) has a poor prognosis, necessitating the investigation of novel treatments and targets. This study evaluated JNJ-70218902 (JNJ-902), a T-cell redirector targeting transmembrane protein with epidermal growth factor-like and 2 follistatin-like domains 2 (TMEFF2) and cluster of differentiation 3, in mCRPC.
Patients And Methods: Patients who had measurable/evaluable mCRPC after at least one novel androgen receptor-targeted therapy or chemotherapy were eligible.
