A multicenter retrospective study of 108 patients demonstrated that tislelizumab, with or without tyrosine kinase inhibitors, significantly extended recurrence-free survival in high-risk hepatocellular carcinoma patients after curative resection.
Patients receiving adjuvant therapy for at least 6 months showed significantly longer recurrence-free survival compared to those treated for less than 6 months, with RFS rates of 89.8%, 71.3%, and 59.3% at 6, 12, and 24 months respectively.
Combination therapy with TKIs did not provide additional survival benefit over tislelizumab monotherapy but resulted in significantly higher rates of grade 3 or higher treatment-related adverse events (38.5% vs 18.6%).
The findings suggest tislelizumab monotherapy may be the optimal adjuvant approach for preventing HCC recurrence, balancing efficacy with acceptable toxicity profiles.
