GC can be classified as immunogenic or immune-resistant based on the infiltration of the tumour microenvironment (TME) from different immune cells (ICs), the most significant of which are activated lymphocytes (a-Ly) CD8+ and CD4+. From the amount of a-Ly infiltration in TME, we can identify tumours with high Immunoscore (IS) which correlates with better prognosis in terms of disease-free survival and overall survival (OS).

The optimal cut-off for survival at 1 year was LFI 4.2 (area under the curve 0.658), significant on univariable and multivariable analyses at predicting death. Frailty was associated with earlier systemic therapy discontinuation, despite similar rates of disease progression and adverse events; cessation of treatment due to functional decline was more common among frail patients. Sensitivity analysis excluding patients above Child–Pugh B8 or ECOG 2 did not change results.</p></div><div><h3>Conclusion</h3><p>The LFI is an independent predictor of death among patients with HCC undergoing systemic therapy.</p></div>","PeriodicalId":100490,"journal":{"name":"ESMO Gastrointestinal Oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-02-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949819824000049/pdfft?md5=5b23993ef9b436cf939f6aaccd640ba2&pid=1-s2.0-S2949819824000049-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139915515","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
