Abstract

Rationale and objectives: The purpose of this study was to demonstrate the impact of postoperative adjuvant transarterial chemoembolization (TACE) on the prognosis of patients with macrotrabecular-massive hepatocellular carcinoma (MTM-HCC).

Materials and methods: This retrospective study used the clinical records of patients with resected MTM-HCC with/without adjuvant TACE at three centers between January 2015 and December 2022. The primary end point was recurrence free survival (RFS). The secondary end points were overall survival (OS) and safety.

Results: A total of 559 eligible patients were classified into the adjuvant TACE group and the observation group. After propensity score matching analysis, both RFS (HR 0.62 [95% CI, 0.48 to 0.80]; P < 0.001) and OS (HR 0.59 [95% CI, 0.42 to 0.84]; P = 0.013) in the adjuvant TACE group were significantly better than the observation group. By Cox regression models, mALBI grade, types of hepatectomy, number, satellite lesion, without adjuvant TACE were identified as independent risk factors for RFS, and mALBI grade, number, maximum tumor size, satellite lesion, microvascular invasion, high AFP level, without adjuvant TACE were identified as independent risk factors for OS. The incidence of surgery-related adverse events (AEs) had no significant difference between the two groups (P = 0.609). The majority of AEs associated with adjuvant TACE were grade I (84.4%), and no treatment-related deaths occurred in either group.

Conclusions: Adjuvant TACE significantly improved the RFS and OS of patients with resected MTM-HCC with acceptable toxicity.
