In the setting of castrate-resistant prostate cancer, patients present with a variety of symptoms, including bone metastases, spinal cord compression and advanced pelvic disease. Fortunately, a variety of radiotherapeutic options exist for palliation. This article focuses on these options, including both external beam radiotherapy and radiopharmaceuticals.

Purpose: Actinium-225 labeled prostate-specific membrane antigen (PSMA) targeted radionuclide therapy has emerged as a potential treatment option in the management of men with metastatic castrate-resistant prostate cancer (mCRPC). This study investigated molecular imaging-derived parameters and compared imaging response of lesions categorized by tumor site.
Methods: Men with mCRPC treated with [225Ac]Ac-J591 from 2017 to 2022 at our center on two prospective trials (NCT03276572 and NCT04506567) with pre- and post-treatment [68Ga]Ga-PSMA-11 Positron Emission Tomography (PET) imaging studies available were included.

Background: Lu-prostate-specific membrane antigen (PSMA)-617 (LuPSMA) is a radionuclide therapy approved for patients with PSMA-avid metastatic castrate-resistant prostate cancer (mCRPC). We evaluated whether alterations in the DNA damage repair (DDR) pathway were associated with outcomes to LuPSMA.
Patients And Methods: We identified an institutional cohort of men (n = 134) treated with ≥2 cycles of LuPSMA who had panel-based germline and/or tumor genomic sequencing.

Objectives: Prostate cancer (PCa) is a leading cause of cancer death in men worldwide. Approximately 30% of castrate-resistant PCa becomes refractory to therapy due to neuroendocrine differentiation (NED) that is present in <1% of de-novo tumors. First-in-class imipridone ONC201/TIC10 therapy has shown clinical activity against midline gliomas, neuroendocrine tumors, and PCa.

Prostate cancer represents the predominant malignant neoplasm observed in the male population and ranks second in terms of mortality attributable to malignant neoplasm among men. Decursinol angelate (DA), derived from the plant Nakai (AGN), has demonstrated anti-cancer effectiveness through the induction of intrinsic and extrinsic apoptosis pathways, inhibition of cancer cell proliferation, having anti- neovascularization, anti-inflammatory anti-oxidative activities and stimulating the immune process. The aim of this study was to determine the IC50 dose of DA on human prostate cancer cell line PC-3, as well as to assess its effects on cell viability and apoptosis.

Androgen receptor (AR) signaling is a target in prostate cancer therapy and can be treated with non-steroidal anti-androgens (NSAA) including enzalutamide, and apalutamide for patients with advanced disease. Metastatic castration-resistant prostate cancer (mCPRC) develop resistance becomes refractory to therapy limiting patient overall survival. Darolutamide is a novel next-generation androgen receptor-signaling inhibitor that is FDA approved for non-metastatic castration resistant prostate cancer (nmCRPC).
