The purpose of this study was to evaluate the added role of a chemotherapeutic in transarterial chemoembolization (TACE) of intermediate-stage hepatocellular carcinoma (HCC). The issue is of major importance since, as suggested by recent evidence, hypoxia or incomplete devascularization of the tumor is a potent stimulator of angiogenesis, and there are not many papers supplying level one evidence confirming the value of a chemotherapeutic. The hypothesis was that since drug-eluting bead (DEB)-TACE is standardized and reproducible, a comparison with bland TACE can readily reveal the potential value of the chemotherapeutic. Two groups were randomized in this prospective study: group A (n = 41) was treated with doxorubicin DEB-TACE, and group B (n = 43) with bland embolization. Patients were randomized for tumor diameter. Patients were embolized at set time intervals (2 months), with a maximum of three embolizations. Tumor response was evaluated using the EASL criteria and alpha-fetoprotein levels. At 6 months a complete response was seen in 11 patients (26.8%) in the DEB-TACE group and in 6 patients (14%) in the bland embolization group; a partial response was achieved in 19 patients (46.3%) and 18 (41.9%) patients in the DEB-TACE and bland embolization groups, respectively. Recurrences at 9 and 12 months were higher for bland embolization (78.3% vs. 45.7%) at 12 months. Time to progression (TTP) was longer for the DEB-TACE group (42.4 +/- 9.5 and 36.2 +/- 9.0 weeks), at a statistically significant level (p = 0.008). In conclusion, DEB-TACE presents a better local response, fewer recurrences, and a longer TTP than bland embolization with BeadBlock. However, survival benefit and bland embolization with smaller particles must be addressed in future papers to better assess the clinical value.
本研究旨在评估在经动脉化疗栓塞术(TACE)治疗中晚期肝细胞癌(HCC)中添加化疗药物的作用。这个问题非常重要,因为最近的证据表明,肿瘤缺氧或不完全血管化是血管生成的强大刺激因素,而且很少有论文提供一级证据证实化疗药物的价值。我们的假设是,由于载药微球(DEB)-TACE 是标准化和可重复的,因此与单纯 TACE 相比,可以很容易地揭示化疗药物的潜在价值。在这项前瞻性研究中,将患者随机分为两组:A 组(n = 41)接受多柔比星 DEB-TACE 治疗,B 组(n = 43)接受单纯栓塞治疗。患者按肿瘤直径随机分组。患者在设定的时间间隔(2 个月)内进行栓塞,最多进行三次栓塞。使用 EASL 标准和甲胎蛋白水平评估肿瘤反应。在 6 个月时,DEB-TACE 组有 11 例(26.8%)患者完全缓解,单纯栓塞组有 6 例(14%)患者完全缓解;DEB-TACE 组和单纯栓塞组分别有 19 例(46.3%)和 18 例(41.9%)患者部分缓解。在 9 个月和 12 个月时,单纯栓塞组的复发率更高(78.3%比 45.7%)。DEB-TACE 组的无进展时间(TTP)更长(42.4 +/- 9.5 和 36.2 +/- 9.0 周),具有统计学意义(p = 0.008)。总之,与 BeadBlock 单纯栓塞相比,DEB-TACE 具有更好的局部反应、更少的复发和更长的 TTP。然而,未来的论文必须探讨生存获益和使用较小颗粒的单纯栓塞,以更好地评估其临床价值。
