177 Lu-Microspheres Selective Intra-arterial Radionuclide Therapy : A Facile and Biocompatible Permanent Micro-Seed Implants for Unresectable Hepatocellular Carcinoma

Clin Nucl Med. 2024 Apr 1;49(4):e170-e171. doi: 10.1097/RLU.0000000000005101. Epub 2024 Feb 6.

Abstract

Hepatocellular carcinoma (HCC) is an aggressive malignancy with a poor prognosis. Surgical resection is limited. Selective intra-arterial radionuclide therapy (SIRT) emerged as a potential cure for intermediate HCC with portal vein thrombosis. We report a pilot study of a 48-year-old man with recurrent HCC who underwent 177 Lu-microsphere SIRT (2.2 GBq) in segment III. Posttherapy SPECT/CT images (24 hours to 3 months) demonstrated excellent localization and prolonged retention within the tumor. Pre- and 3-month post-SIRT CECT showed a notable decrease in arterial enhancement and tumor size. Time-activity curve of the standard and the lesion demonstrated similar decay pattern indicating that 177 Lu-microspheres act as permanent implant.
