ADVERSE EVENTS, ADVERSE EVENT
The treatment of sudden adverse events (AEs) was primarily evaluated based on their frequency and severity grade, following the guidelines of the Common Terminology Criteria for Adverse Events version 4.03. Almost all patients experienced transient fever following RFA, which resolved within a short period of time in the majority of cases. As a result, we did not include these transient AEs caused by the procedure in our summary.As shown in Table Treatment emergent adverse events.Abbreviations: AKP, alkaline phosphatase; ALT, alanine aminotransferase; anti‐PD‐1, toripalimab; AST, aspartate aminotransferase; RFA, radiofrequency ablation.
