Preoperative transcatheter arterial chemoembolization (TACE) is administered to improve long-term outcome after surgical resection of hepatocellular carcinoma (HCC). However, the survival benefit of preoperative TACE is controversial. We conducted a retrospective case-control study to evaluate the effect of preoperative TACE on prognosis.
A total of 121 patients who underwent curative resection of HCC were divided into two groups according to whether they received preoperative TACE. We determined the control group ( = 34) and TACE group ( = 34) through propensity score matching. The primary endpoint of this study was overall survival, and the secondary endpoints were recurrence-free survival.
The overall survival rate and the recurrence free survival rate were significantly lower in the TACE group than in the control group ( = 0.014 and = 0.043, respectively). Furthermore, recurrence free survival within less than 2 years after resection was significantly worse in the TACE group than in the control group ( = 0.035).
Preoperative TACE seemed to worsen the long-term outcomes of the patients who underwent surgical resection for the treatment of resectable HCC. Therefore, preoperative TACE should not be considered as a standard therapy in patients with resectable HCC.
术前经动脉化疗栓塞术(TACE)用于改善肝细胞癌(HCC)手术切除后的长期预后。然而,术前TACE的生存获益存在争议。我们进行了一项回顾性病例对照研究,以评估术前TACE对预后的影响。
总共121例行HCC根治性切除术的患者根据是否接受术前TACE分为两组。我们通过倾向评分匹配确定了对照组(n = 34)和TACE组(n = 34)。本研究的主要终点是总生存期,次要终点是无复发生存期。
TACE组的总生存率和无复发生存率显著低于对照组(分别为P = 0.014和P = 0.043)。此外,TACE组切除后2年内的无复发生存情况明显比对照组差(P = 0.035)。
术前TACE似乎会使接受手术切除治疗可切除HCC患者的长期预后恶化。因此,术前TACE不应被视为可切除HCC患者的标准治疗方法。
