ILICI is a serious irAE that, when severe, requires cessation of ICI and initiation of immunosuppression. Cytotoxic T Lymphocytes (CTLs) play a central role in ILICI; however, they are just part of the picture as immunotherapy broadly impacts all aspects of the immune microenvironment and can directly and indirectly activate innate and adaptive immune cells. Clinically, as our understanding of this entity grows, we encounter new challenges. The presentation of ILICI is heterogeneous with respect to latency, pattern of injury (hepatitis vs. cholangitis) and severity. This review focuses on our knowledge regarding risk factors, presentation and treatment of ILICI including ILICI refractory to steroids. An emerging topic, the possibility of rechallenge while accepting some risk, in patients who experience ILICI but require immunotherapy, is also discussed.

The underlying mechanisms and risk factors for severe hepatotoxicity with novel oncology therapies are not well understood, complicating the drug-induced liver injury (DILI) risk assessment in the preclinical and clinical phases of drug development. The epidemiological and clinical characteristics, as well as mechanisms of liver toxicity, are described here to the current state of knowledge. Tools to study and assess the risk of DILI during drug development are concisely summarised, focusing on caveats thereof for novel oncology treatments. Emerging tools to optimise safety assessments and gather additional mechanistic insights into DILI are introduced. Particularly in oncology, where standard liver signals during drug development are tolerated to a marginally higher degree than in other indications due to the life-saving, life-extending and quality-of-life improvements for patients with severe or advanced cancers versus previous standard-of-care therapeutics, safety assessments must be tailored to the drug and indication.

The expression of genes related to de Novo lipogenesis (DNL) and fatty acid oxidation (FAO) has been analysed by quantitative RT-PCR and/or interrogation of RNA-seq datasets in 259 pairs of tissues (MASLD-HCC vs. VIRUS-HCC).</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Results</h3>\u0000 \u0000 <p>Metabolomic analysis revealed that acylcarnitines were the main discriminating metabolites according to fibrosis severity when we compared MASLD-HCC-F0F1-F2 versus NTT and MASLD-HCC-F3F4 versus NTT. Based on these metabolomic data, the analysis of a panel of 15 selected genes related to DNL and FAO indicated that there is no difference between the 2 groups of MASLD-HCC. In contrast the same comparative gene analysis according to the aetiology of HCC: MASLD-HCC versus VIRUS-HCC showed that both aetiologies shared the same upregulation of genes involved in DNL. However, five genes involved in FAO (HADHA, CRAT, CPT1, CPT2 and PPARA) are upregulated exclusively in MASLD-HCC. This result indicates that FAO and DNL pathways are simultaneously activated in MASLD-HCC in contrast to VIRUS-HCC.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Conclusions</h3>\u0000 \u0000 <p>These results suggest that, the involvement of adaptive metabolic pathways is different depending on the aetiology of HCC.
