| 2 | Facile preparation of^(177)Lu-microspheres for hepatocellular carcinoma radioisotope therapy显示文摘As one of the most common cancers in the world,hepatocellular carcinoma(HCC)has become a major threat to human health.Radioembolization is a first-line option for the treatment of HCC,especially when other conventional treatments fail or there exist some relative contraindications.Herein,we developed a facile and efficient method for preparing ^(177)Lu-microspheres potentially useful for precise radioembolization therapy of HCC.The radiolabeling efficiency of ^(177)Lu-microspheres was as high as 96.8%±0.5%,and the radiolabeling process did not alter the morphology of the mother microspheres.The SPECT/CT studies enabled by the unique emissions of ^(177)Lu suggested that almost no ^(177)Lu ion loaded by the microspheres was released over more than 32 d in vivo,which led to remarkable inhibition effect on the growth of HepG2 tumors subcutaneously transplanted in mice.The current approach may thus offer promising ^(177)Lu-microspheres for clinical radioembolization of HCC. | Manran Wu Kexin Shi Ruizhe Huang Chunyi Liu Lingling Yin Weipeng Yong Jing Sun Guanglin Wang Zhiyuan Zhong Mingyuan Gao | 2022 | Chinese Chemical Letters2022，33，7： | 0 |
