Background
Microvascular invasion (MVI) is a risk factor for tumor recurrence after hepatectomy in hepatocellular carcinoma (HCC) patients.
Objective
This study aimed to investigate the efficacy and safety of postoperative adjuvant transarterial infusion chemotherapy (TAI) with the FOLFOX regimen for HCC patients with MVI.
Methods
In this prospective, phase III, randomized, open-label, controlled clinical trial, HCC patients with histologically confirmed MVI were randomly assigned (1:1) after hepatectomy to receive either one to two cycles of adjuvant TAI (AT group) or follow-up without any adjuvant treatment (FU group). The primary endpoint was disease-free survival (DFS), while secondary endpoints were overall survival (OS) and safety.
Results
Between June 2016 and April 2019, 127 patients were randomly assigned to the AT group (n = 63) or FU group (n = 64). Clinicopathological characteristics of the two groups were well-balanced. The 6-, 12-, and 18-month OS rates for the AT group were 100.0%, 97.7%, and 97.7%, respectively, and 94.5%, 89.6%, and 78.5% for the FU group, respectively. The 6-, 12-, and 18-month DFS rates for the AT and FU groups were 84.7%, 61.8%, and 58.7%, and 62.9%, 48.1%, and 38.6%, respectively. OS and DFS were significantly better in the AT group than in the FU group (p = 0.037 and 0.023, respectively). No patients in the AT group experienced grade 3 or more severe adverse events.
Conclusions
Adjuvant TAI after hepatectomy may bring survival benefits to HCC patients with MVI.
