Introduction: Analysis of total value of prostate specific antigen (PSAT), with the unavoidable digital rectal examination (DRE) is the basis of prostate cancer detection.
Aim: The aim of this study was to determine the specificity and sensitivity of the total value of PSAT in the diagnosis of prostate cancer. The aim was also to determine the significance of PSAT in diagnosis of benign prostate hyperplasia, precancerous conditions and inflammatory and atrophic changes of the prostate.
Material And Methods: Data were collected from the "Register of PH biopsy" of Clinic of Urology, CCU Sarajevo.
Results: Analysis of correlation between the diagnosis and the PSAT value shows statistically significant negative correlation (r =-0,186; p = 0.006) in the sense that the value of the PSAT is highest in cancer patients, and the lowest in patients with benign prostatic hyperplasia. PSAT increases with age (r = 0.152; p = 0.025). For prostate cancer optimal sensitivity and specificity for PSAT value occurs at cut off value of> 8.6 ng /mL. Values lower than 2 ng/mL and higher than 10 ng/mL are most specific, and PPV increases with increasing value of PSAT. PSAT at values of <2 ng/mL and > 10 ng/mL are at high levels of specificity, and value > 10 ng / mL is also of high sensitivity in the detection of prostate cancer, and in this moment these values represent the optimal mode for the subsequent treatment.
Conclusion: PSAT has a relative significance in the detection of prostate cancer, and should not be used as a guideline without DRE.

Preliminary evaluation of a novel PSMA-targeting radiopharmaceutical [Ga]Ga/[Lu]Lu-NYM032 for theranostic use in prostate cancer.

Purpose: A novel theranostic radiopharmaceutical targeting prostate-specific membrane antigen (PSMA), [Ga]Ga/[Lu]Lu-NYM032, was developed and its diagnostic and therapeutic potential in the treatment of prostate cancer (PCa) was preliminarily evaluated.
Methods: The diagnostic efficacy of the PET tracer [Ga]Ga-NYM032 was first evaluated in PSMA-positive xenograft-bearing models (LNCaP models), followed by evaluation in 10 PCa patients using [Ga]Ga-PSMA617 a comparator. Finally, the therapeutic potential of [Lu]Lu-NYM032 was evaluated in LNCaP models.

Background: Prostate cancer therapy with surgical or chemical castration with GnRH agonists has been linked to elevated FSH levels, which may contribute to secondary health disorders, including atherosclerosis and diabetes. Although recent findings suggest a role for FSH beyond the reproductive system, its metabolic impact remains unclear and difficult to disentangle from that of androgens. In this study, we examined the metabolic changes induced by FSH and distinguished them from those caused by testosterone.

Purpose: 10-15% of prostate cancers (PCa) harbor recurrent FOXA1 aberrations whereby the alteration type and the effect on the forkhead( FKH) domain impacts protein-function. We developed a FOXA1 classification system to inform clinical management.
Experimental Design: 5,014 PCa were examined using whole exome and transcriptome sequencing from the Caris database.

Genetically engineered mouse models (GEMMs) are instrumental for modelling local and systemic features of complex diseases such as cancer. Non-invasive, longitudinal cell detection and monitoring in tumors, metastases and/or the micro-environment is paramount to achieve a better spatiotemporal understanding of cancer progression and to evaluate therapies in preclinical studies. Bioluminescent and fluorescent reporters marking tumor cells or their microenvironment are valuable for non-invasive cell detection and monitoring in vivo.
