ABSTRACT
BACKGROUND:
Conversion therapy for initially unresectable hepatocellular carcinoma (iuHCC) using lenvatinib combined with transcatheter arterial chemoembolization (TACE) plus a PD-1 inhibitor (LTP) has achieved promising results. However, further comparative research is necessary to evaluate the effectiveness and safety of conversion surgery (CS) for iuHCC.METHODS:
Data for 32 consecutive patients with iuHCC receiving CS and 419 consecutive patients with resectable HCC receiving initial surgery (IS) between November 2019 and September 2022 were collected retrospectively. After propensity score matching (PSM), 65 patients were selected.RESULTS:
Before matching, the CS group had longer EFS (not reached vs. 12.9 months, P < 0.001) and similar OS (not reached vs. not reached, P = 0.510) compared with the IS group. Similar results for EFS (P = 0.001) and OS (P = 0.190) were obtained after matching. The multivariable Cox model (HR = 0.231, 95% CI 0.105-0.504; P < 0.001) and subgroup analyses confirmed that CS could improve EFS. The CS group had significantly lower incidence of microvascular invasion (MVI) than the IS group (3.1% vs. 50.4%, P < 0.001). Moreover, the two groups had similar safety profiles.CONCLUSIONS:
CS is effective and safe for patients with iuHCC receiving LTP. LTP has the potential to reduce risk factors for postoperative recurrence, especially MVI, which may influence surgical decision-making.Key words
