Abstract

Pretreatment dual-tracer (F-fluorodeoxyglucose and C-acetate) PET/computed tomography (CT) has potential to predict treatment response for Y microsphere radioembolization (RE) in patients with inoperable hepatocellular carcinoma (HCC). Patients with C-acetate-avid HCC have a better response to Y microsphere RE, and possibly better survival. Pretreatment dual-tracer PET/CT has a significant theranostic value on Y microsphere RE in determining target tumor dose for HCCs with different cellular differentiation, metabolic tumor volume, and functioning liver volume, and can be used to prescribe individual injected activity of Y microspheres.

摘要

治疗前双示踪剂(F-氟脱氧葡萄糖和C-乙酸盐)正电子发射断层显像/计算机断层扫描(PET/CT)有潜力预测不可切除肝细胞癌(HCC)患者接受钇90微球放射性栓塞(RE)治疗的反应。C-乙酸盐摄取阳性的HCC患者对钇90微球RE反应更好,且可能有更好的生存期。治疗前双示踪剂PET/CT在确定不同细胞分化、代谢肿瘤体积和功能性肝体积的HCC的靶肿瘤剂量方面,对钇90微球RE具有显著的诊疗价值,可用于个体化确定钇90微球的注射活度。
