Abstract
[PURPOSE] Huge (≥10 cm) hepatocellular carcinoma (HCC) poses significant treatment and prognosis challenges. This study aimed to determine whether preoperative transarterial chemoembolization (TACE) for huge HCC is necessary.
[METHODS] This single-center, retrospective cohort study evaluated 435 patients with huge HCC who underwent upfront hepatectomy or hepatectomy after preoperative TACE from January 2009 to December 2018. TACE's impact on survival and prognostic factors, including microvascular invasion (MVI) and satellite nodules (SNs), was analyzed.
[RESULTS] The preoperative TACE group (n = 33) had a lower incidence of MVI (P = 0.009) and higher postoperative morbidity (P = 0.001), particularly pleural effusion (P = 0.004) and Clavien-Dindo class III-IV complications (P = 0.033), compared with the upfront hepatectomy group (n = 402). Short-term mortality (P = 0.828) and recurrence within 6 months (P = 0.654) were comparable between groups. The 1-, 3-, and 5-year survival curves showed no significant between-group differences in recurrence-free survival (RFS) (P = 0.172) and overall survival (OS) (P = 0.450). Local regional therapy for intrahepatic recurrences and surgical resection for extrahepatic recurrences were associated with better OS. MVI, SN, and hepatic vein tumor thrombosis were identified as significant risk factors for poorer RFS and OS. In patients without SN, preoperative TACE improved RFS (P = 0.039) but not OS.
[CONCLUSION] Preoperative TACE for huge HCC was associated with reduced MVI but did not improve RFS and OS. Survival outcomes were more significantly influenced by SN, suggesting that upfront hepatectomy without TACE should be prioritized.
