Abstract
Abstract: In the evolving landscape of precision oncology, this review delineates the role of radiopharmaceuticals targeting the norepinephrine transporter (NET), with a particular focus on the current clinical application of 123I-MIBG diagnostic imaging and 131I-MIBG therapeutics, in particular for pheochromocytoma, neuroblastoma, or paraganglioma. We will also highlight recently introduced 18F-labeled NET targeting imaging radiotracers, which would offer unparalleled resolution, enhanced tumor localization, and staging properties. Complementing these novel second-generation PET agents in a theranostic approach, astatine-211 meta-astatobenzylguanidine (211At-MABG) would leverage the advantages of alpha-particles to selectively target and eradicate NET-expressing tumor cells with minimal off-target effects.
摘要：在精准肿瘤学不断发展的背景下，本综述阐述了靶向去甲肾上腺素转运体（NET）的放射性药物的作用，特别关注123I-MIBG诊断成像和131I-MIBG治疗的当前临床应用，尤其是嗜铬细胞瘤、神经母细胞瘤或副神经节瘤。我们还将重点介绍最近推出的 18F 标记的 NET 靶向成像放射性核素，它们将提供无与伦比的分辨率、更强的肿瘤定位和分期特性。砹-211元-天冬氨苄胍（211At-MABG）将利用α粒子的优势，选择性地靶向和清除表达NET的肿瘤细胞，同时将脱靶效应降到最低，是治疗方法中对这些新型第二代PET制剂的补充。
