The present study explored outcomes associated with the treatment of infiltrative HCC with various systemic therapies.Patients and Methods: We enrolled all patients with Barcelona Clinic Liver Cancer stage C infiltrative or multinodular HCC who received first-line systemic therapy between January 2015 and December 2021 at a single center. We compared baseline characteristics and treatment outcomes for the two HCC subtypes.Results: In total, 260 patients were enrolled, 128 (49.2%) of whom had infiltrative HCC. Patients with infiltrative HCC were more likely to have macrovascular invasion (91.4% vs 68.2%, p < 0.001) but less likely to have extrahepatic spread (32.0% vs 54.5%, p < 0.001) than patients with multinodular HCC. In patients who received multikinase inhibitors alone, the time to treatment failure (TTF) and overall survival (OS) were similar for the 2 HCC subtypes. In patients who received immune checkpoint inhibitor (ICI)-based therapy, multivariate analyses revealed that infiltrative HCC was associated with shorter TTF (HR: 4.07, 95% CI: 2.13– 7.79, p < 0.001) and poorer OS (HR: 3.27, 95% CI: 1.76– 6.11, p < 0.001).Conclusion: In patients receiving ICI-based therapy for HCC, infiltrative HCC was associated with poorer outcomes.Keywords: hepatocellular carcinoma, HCC, infiltrative, systemic therapy, multikinase inhibitor, immune checkpoint-inhibitor |
