Article Abstract

A 72-year-old man underwent Ga-PSMA PET/CT because of an elevated prostate-specific antigen level despite prior prostatectomy. Besides low-intensity prostatic PSMA reactivities, a faintly PSMA-positive lesion in the pancreatic corpus drew attention, which seemed suggestive of a primary pancreatic cancer on the subsequent MRI and therefore had to be excised. The final diagnosis was pT3 low-grade neuroendocrine tumor. PSMA-positive incidentalomas, detected on Ga-PSMA PET/CT, can reveal more clinically significant extraprostatic disorders.

Predictive value of metastatic distribution patterns on [Ga]Ga-PSMA PET/CT for [Lu]Lu-PSMA therapy.

Objective: This study aimed to assess the predictive value of metastatic distribution patterns on Ga-PSMA-11 PET/CT in patients with chemotherapy- and castration-resistant prostate cancer undergoing ¹⁷⁷Lu-PSMA-617 radioligand therapy.

Materials And Methods: A retrospective analysis was conducted on 48 patients who received ¹⁷⁷Lu-PSMA-617 therapy between April 2019 and August 2023. Demographic, clinical, and laboratory data, along with pre- and post-treatment Ga-PSMA-11 PET/CT images, were evaluated for associations with molecular response and progression.

We designed and synthesized a novel type of PSMA radioligand incorporating (2, 3) β-branched aromatic α-amino acids within the linker segment of its structure. PET/CT imaging and biodistribution analysis revealed that β-branched aromatic α-amino acids modified PSMA radioligands could maintain or even improve tumor targeting while exhibiting a more rapid renal clearance rate than [Ga]Ga-. With average renal uptake of less than 10%ID/g, as opposed to 25%ID/g for [Ga]Ga-, this substantial decrease in renal accumulation translates to a significantly improved safety profile by minimizing nephrotoxic risks.

Purpose: While PSMA-targeted radioligand therapy (RLT) has shown remarkable efficacy for treating end-stage prostate cancer, the α-emitting RLT often results in severe salivary gland toxicity, limiting its use. Various strategies to mitigate this side effect have been attempted with limited success. Accordingly, this study introduced a new PSMA-targeting ligand with more favorable binding characteristics than the existing ligands.

Background: Body composition (BC) analysis is performed to quantify the relative amounts of different body tissues as a measure of physical fitness and tumor cachexia. We hypothesized that relative changes in body composition (BC) parameters, assessed by an artificial intelligence-based, PACS-integrated software, between baseline imaging before the start of radioligand therapy (RLT) and interim staging after two RLT cycles could predict overall survival (OS) in patients with metastatic castration-resistant prostate cancer.

Methods: We conducted a single-center, retrospective analysis of 92 patients with mCRPC undergoing [Lu]Lu-PSMA RLT between September 2015 and December 2023.

Targeted alpha therapy (TAT) has recently emerged as a highly promising approach for the management of metastatic castration-resistant prostate cancer (mCRPC), especially in patients with disease progression despite standard treatments. Among alpha-emitter radiopharmaceuticals, actinium-225-labelled prostate-specific membrane antigen ([225Ac]Ac-PSMA) has shown remarkable potential due to its high linear energy transfer (LET), short path length, and ability to induce potent, localised cytotoxic effects. This review summarises current clinical evidence regarding [225Ac]Ac-PSMA radioligand therapy (RLT), emphasising its efficacy, safety profile, and position relative to beta-emitter therapy with lutetium-177 ([177Lu]Lu-PSMA).
