背景：关于伴微血管侵犯(MVI)的单发性肝细胞癌(HCC)患者在根治术后辅助治疗的最佳方案一直存在争议。本试验旨在评估肝切除术后辅助经动脉化疗栓塞(TACE)与单纯肝切除术对直径≥5cm单发肿瘤伴MVI的HCC患者的疗效和安全性。
Methods:Inthisrandomized,open-labeled,phaseIIItrial,HCCpatientswithasolitarytumor≥5cmandMVIwererandomlyassigned(1:1)toreceiveeither1–2cyclesofadjuvantTACEafterhepatectomy(Hepatectomy-TACE)orhepatectomyalone(HepatectomyAlone).Theprimaryendpointwasdisease-freesurvival(DFS);thesecondaryendpointsincludedoverallsurvival(OS)andadverseevents.
方法：在本随机、开放性、Ⅲ期试验中，将直径≥5cm单发肿瘤伴MVI肝细胞癌患者随机分为两组(1：1)：在肝切除术后接受1-2个周期的辅助TACE治疗(肝切除-TACE组)或单纯接受肝切除(单纯肝切除组)。主要终点是无病生存期(DFS)，次要终点包括总生存期(OS)和不良事件。
