【摘要】 钇-90选择性内放射治疗（Yttrium-90 selective internal radiation therapy,90Y-SIRT）是一种通过将放射性微球精准输送至肿瘤动脉血管床，利用β射线对肿瘤组织进行局部高剂量放射治疗的技术。该技术已在不可手术的原发性肝癌及转移性肝癌患者中展现出显著疗效。本文系统综述了90Y-SIRT在肝癌治疗中的发展历程和临床应用现状，并展望其未来发展方向。更多还原

【Abstract】 Yttrium-90 selective internal radiation therapy(90Y-SIRT) is a treatment technique that delivers radioactive microspheres precisely to the arterial vascular bed of neoplasms, utilizing beta radiation to administer a high local dose of radiation to the neoplasm tissues. This technology has demonstrated significant efficacy in patients with unresectable pirmary liver cancers and liver metastases. This article systematically reviews the development history and clinical application status of 90Y-SIRT in the treatment of liver cancer, and looks forward to future development directions.更多还原
