Transcatheter arterial chemoembolization (TACE) offers a survival benefit to patients with intermediate hepatocellular carcinoma (HCC). A widely accepted TACE regimen includes administration of doxorubicin-oil emulsion followed by gelatine sponge-conventional TACE. Recently, a drug-eluting bead (DC Bead) has been developed to enhance tumor drug delivery and reduce systemic availability. This randomized trial compares conventional TACE (cTACE) with TACE with DC Bead for the treatment of cirrhotic patients with HCC. Two hundred twelve patients with Child-Pugh A/B cirrhosis and large and/or multinodular, unresectable, N0, M0 HCCs were randomized to receive TACE with DC Bead loaded with doxorubicin or cTACE with doxorubicin. Randomization was stratified according to Child-Pugh status (A/B), performance status (ECOG 0/1), bilobar disease (yes/no), and prior curative treatment (yes/no). The primary endpoint was tumor response (EASL) at 6 months following independent, blinded review of MRI studies. The drug-eluting bead group showed higher rates of complete response, objective response, and disease control compared with the cTACE group (27% vs. 22%, 52% vs. 44%, and 63% vs. 52%, respectively). The hypothesis of superiority was not met (one-sided P = 0.11). However, patients with Child-Pugh B, ECOG 1, bilobar disease, and recurrent disease showed a significant increase in objective response (P = 0.038) compared to cTACE. DC Bead was associated with improved tolerability, with a significant reduction in serious liver toxicity (P < 0.001) and a significantly lower rate of doxorubicin-related side effects (P = 0.0001). TACE with DC Bead and doxorubicin is safe and effective in the treatment of HCC and offers a benefit to patients with more advanced disease.
经导管动脉化疗栓塞(TACE)为中危肝癌(HCC)患者带来生存获益。一种被广泛接受的 TACE 方案包括阿霉素油乳剂给药,随后进行明胶海绵-常规 TACE。最近,开发了一种载药微球(DC Bead),以增强肿瘤药物递送并减少全身药物暴露。这项随机试验比较了常规 TACE(cTACE)与载药微球 TACE(DC Bead-TACE)治疗肝硬化合并大肝癌或/和多结节、不可切除、N0、M0 HCC 患者的疗效。将 212 例 Child-Pugh A/B 肝硬化、大肝癌或/和多结节、不可切除、N0、M0 HCC 患者随机分为接受载药微球 TACE(阿霉素)或 cTACE(阿霉素)。随机化按 Child-Pugh 状态(A/B)、体力状态(ECOG 0/1)、双叶病变(是/否)和既往根治性治疗(是/否)分层。主要终点为 MRI 独立盲法评估 6 个月后的肿瘤反应(EASL)。载药微球组完全缓解率、客观缓解率和疾病控制率均高于 cTACE 组(27% vs. 22%、52% vs. 44%和 63% vs. 52%)。优势假设未被证实(单侧 P = 0.11)。然而,Child-Pugh B、ECOG 1、双叶病变和复发性疾病患者的客观缓解率显著增加(P = 0.038)。与 cTACE 相比,载药微球 TACE 具有更好的耐受性,严重肝毒性显著降低(P < 0.001),阿霉素相关副作用发生率显著降低(P = 0.0001)。载药微球 TACE 联合阿霉素治疗 HCC 安全有效,可为晚期疾病患者带来获益。
