<p>This record contains raw data related to article &quot;Hepatotoxicity in Patients with Hepatocellular Carcinoma on Treatment with Immune Checkpoint Inhibitors&quot;</p> <p>Risk factors for hepatic immune-related adverse events (HIRAEs) in patients with advanced/unresectable hepatocellular carcinoma (HCC) treated with immune checkpoint inhibitors (ICIs) are unclear. We investigated: (i) clinical and morpho-pathological predictors of HIRAEs in 27 pretreatment tumor specimens, including surrogate biomarkers of the HCC immune class (based on intratumoral tertiary lymphoid structures, and glutamine synthase, CD3, and CD79 expression); and (ii) the relationship between HIRAE onset and subsequent treatment outcomes. Fifty-eight patients were included-20 (34%) received ICIs alone, and 38 (66%) received ICIs plus targeted agents as first- or further-line treatment. After a median time of 0.9 months (range, 0.4-2.7), nine patients (15.5%) developed grade &ge; 3 hepatitis, which was significantly associated with higher baseline ALT levels (<em>p</em> = 0.037), and an infectious HCC etiology (<em>p</em> = 0.023). ICIs were safely resumed in six out of nine patients. Time to treatment failure (TTF) was not significantly different in patients developing grade &ge; 3 hepatitis vs. lower grades (3.25 vs. 3.91 months, respectively; <em>p</em> = 0.81). Biomarker surrogates for the HCC immune class were not detected in patients developing grade &ge; 3 hepatitis. Grade &ge; 3 hepatitis has a benign course that does not preclude safe ICI reintroduction, without any detrimental effect on TTF.</p>
