Purpose Of Review: In the era of precision medicine, the introduction of FDA-approved prostate-specific membrane antigen (PSMA) targeting tracers has revolutionized prostate cancer imaging. These tracers enable functional positron emission tomography (PET) imaging, allowing for precise identification of the location and extent of prostate cancer spread. This review serves as a practical guide for multidisciplinary teams caring for prostate cancer patients, outlining the current approved uses of PET imaging with PSMA tracers and exploring its future applications.
Recent Findings: PSMA PET/CT has become a reliable modality for initial staging in patients with intermediate-to-high risk prostate cancer, restaging in cases of biochemical recurrence and further clarifying disease status among patients with conventional imaging based nonmetastatic castrate resistant prostate cancer and metastatic prostate cancer. Additionally, it has promising roles in selecting patients for radioligand therapy, monitoring treatment response, and guiding therapeutic decision-making.
Summary: PSMA PET/CT is currently a crucial imaging tool used at key stages of prostate cancer management, with ongoing research exploring its potential for additional clinical applications.

Socioeconomic Disparities in Prostate Cancer Treatment: The Impact of Area Deprivation Index on Initial Treatment Type for Localized PCa in a North-American Cohort.

Background: Socioeconomic status and geographical location contribute to disparities in localized prostate cancer (PCa) treatment. We examined the impact of area of deprivation index (ADI) on initial treatment type for localized PCa in a North-American cohort.
Methods: We performed a retrospective analysis of patients diagnosed with localized PCa, treated within Henry Ford Health (HFH), between 1995 and 2022, with available ADI-data.
Background And Objective: Prostate cancer (PCa) is a significant global health concern, ranking as the second most prevalent cancer among men worldwide. Genetic factors, particularly germline pathogenic variants (PVs) in DNA repair genes (DRGs), play a crucial role in PCa predisposition. Our study aimed to assess patients' adherence to a targeted PCa screening program targeting high-risk individuals with DRG PVs and evaluate the potential reduction in biopsy and MRI rates by employing our screening protocol.

Background: Ferroptosis is an intracellular iron-dependent cell death that is distinct from apoptosis, necrosis, and autophagy. Increasing evidence indicated that ferroptosis plays a crucial role in suppressing tumors, thus providing new opportunities for cancer therapy. The drug cepharanthine, commonly used to treat leukopenia, has been discovered to function as an anticancer agent to multiple types of cancer via diverse mechanisms.

Introduction: Prostate cancer (PCa) is the most frequent diagnosed malignancy in male patients in Europe and radiation therapy (RT) is a main treatment option. However, current RT concepts for PCa have an imminent need to be rectified in order to modify the radiotherapeutic strategy by considering (i) the personal PCa biology in terms of radio resistance and (ii) the individual preferences of each patient.
Methods: To this end, a mechanistic multiscale model of prostate tumor response to external radiotherapeutic schemes, based on a discrete entity and discrete event simulation approach has been developed.
Hyperactivation of fatty acid biosynthesis holds promise as a targeted therapeutic strategy in prostate cancer (PCa). However, inhibiting these enzymes could potentially promote metastatic progression in various other cancers. Herein, we found that depletion of acetyl-CoA carboxylase 1 (encoded by ACACA), the enzyme responsible for the first and rate-limiting step of de novo fatty acid biosynthesis, facilitated epithelial-mesenchymal transition (EMT) and migration of PCa cells.
