Outcomes of Salvage Surgery Versus Non-Salvage Surgery for Initially Unresectable Hepatocellular Carcinoma After Conversion Therapy with Transcatheter Arterial Chemoembolization Combined with Lenvatinib Plus Anti-PD-1 Antibody: A Multicenter Retrospective Study.

BACKGROUND: Combination treatment with transcatheter arterial chemoembolization (TACE), lenvatinib, and anti-programmed death-1 (anti-PD-1) antibodies (triple therapy) has a high rate of tumor response and converted resection for initially unresectable hepatocellular carcinoma (uHCC) patients. This study aimed to assess the outcomes of salvage surgery in uHCC patients after conversion therapy with triple therapy. METHODS: uHCC patients who met the criteria for hepatectomy after receiving triple therapy as first-line treatment were eligible for inclusion in this study. The overall survival (OS) and progression-free survival (PFS) rates in patients who received salvage surgery (SR group) and those who did not (non-SR group) were compared. RESULTS: Of the 144 patients assessed, 91 patients underwent salvage surgery and 53 did not. The OS rates in the SR group were significantly better than those in the non-SR group. The 1- and 2-year OS rates in the SR group were 92.0% and 79.9%, respectively, whereas those in the non-SR group were 85.5% and 39.6 %, respectively (p = 0.007); however, there was no significant difference in the PFS rates. Upon further stratification, OS and PFS were significantly better in the SR group than in the non-SR group in patients who were assessed as partial responses (PR), while there was no significant difference in patients who were assessed as complete response (CR). CONCLUSIONS: Salvage surgery is recommended and is associated with a favorable prognosis for uHCC patients who were assessed as PR after conversion therapy, however it may not be necessary for uHCC if CR was achieved.

The TAE score predicts prognosis of unresectable HCC patients treated with TACE plus lenvatinib with PD-1 inhibitors.

BACKGROUND AND AIMS: Transcatheter arterial chemoembolization combined with lenvatinib and PD-1 inhibitors (triple therapy) exhibits promising efficacy for unresectable hepatocellular carcinoma (uHCC). We aimed to evaluate the prognosis of patients with uHCC who received triple therapy and develop a prognostic scoring model to identify patients who benefit the most from triple therapy. METHODS: A total of 246 patients with uHCC who received triple therapy at eight centers were included and assigned to the training and validation cohorts. Prognosis was evaluated by the Kaplan-Meier curves. The prognostic model was developed by utilizing predictors of overall survival (OS), which were identified through the Cox proportional hazards model. RESULTS: In the training cohort, the 3-year OS was 52.0%, with a corresponding progression-free survival (PFS) of 30.6%. The median PFS was 13.2 months [95% confidence interval, 9.7-16.7]. Three variables (total bilirubin ≥ 17 µmol/L, alpha-fetoprotein ≥ 400 ng/mL, and extrahepatic metastasis) were predictors of poor survival and were used for developing a prognostic model (TAE score). The 2-year OS rates in the favorable (0 points), intermediate (1 point), and dismal groups (2-3 points) were 96.9%, 61.4%, and 11.4%, respectively (p < 0.001). The PFS was also stratified according to the TAE score. These findings were confirmed in an external validation cohort. CONCLUSIONS: Triple therapy showed encouraging clinical outcomes, and the TAE score aids in identifying patients who would benefit the most from triple therapy.
