Introduction: This retrospective study aimed to compare the efficacy and safety of transarterial chemoembolization plus lenvatinib and programmed death 1 (PD-1) inhibitors versus transarterial chemoembolization plus lenvatinib or sorafenib in patients with unresectable hepatocellular carcinoma. Methods: Consecutive patients with unresectable hepatocellular carcinoma who received transarterial chemoembolization plus lenvatinib and PD-1 inhibitors, lenvatinib, or sorafenib were retrospectively identified in our institution between January 2018 and August 2020. The primary endpoint was overall survival. Results: A total of 84 patients were included in this analysis. The median overall survival was significantly improved in the transarterial chemoembolization plus lenvatinib and PD-1 inhibitor group compared with the transarterial chemoembolization plus sorafenib group (26.7 months [95% confidence interval 25.2-31.6] vs 14.4 months [95% confidence interval 9.5-18.9]; hazard ratio 0.39 [95% confidence interval 0.17-0.72]; P = .007) or the transarterial chemoembolization plus lenvatinib group (26.7 months [95% confidence interval 25.2-31.6] vs 17.9 [95% confidence interval 13.4-22.2] months; hazard ratio 0.45 [95% confidence interval 0.17-0.87]; P = .031). Transarterial chemoembolization plus lenvatinib and PD-1 inhibitor also significantly prolonged median progression-free survival compared with transarterial chemoembolization plus sorafenib group (8.2 months [95% confidence interval 3.3-13.0] vs 6.0 months [95% confidence interval 4.2-7.8]; hazard ratio 0.47 [95% confidence interval 0.24-0.74]; P = .005) or the transarterial chemoembolization plus lenvatinib group (8.2 months [95% confidence interval 3.3-13.0] vs 6.6 [95% confidence interval 4.3-7.9] months; hazard ratio 0.58 [95% confidence interval 0.31-0.96]; P = .047). No significant difference was seen between groups in the incidence of an adverse event or grade 3 or higher adverse event. Conclusion: Transarterial chemoembolization plus lenvatinib, and PD-1 inhibitor was associated with better survival benefits and acceptable toxicities, which may provide an additional therapeutic option for unresectable hepatocellular carcinoma.
