Abstract
Objectives: This study explored the clinical prognosis and lipidomics of hepatitis B virus steatohepatitic hepatocellular carcinoma (HBV-SHHCC) and aimed to identify a noninvasive and convenient method to diagnose this phenotype and guide treatment using MRI.
Methods: A total of 433 HBV-infected HCC patients were enrolled in this retrospective study. Survival data were analyzed using Cox regression analyses, and lipidomics was used to study HCC tissue composition. Logistic regression identified an independent predictor for HBV-SHHCC, and receiver-operating characteristic (ROC) analysis verified its discrimination.
Results: HBV-SHHCC patients had longer disease-free survival (DFS, p < 0.0001) and overall survival (OS) time (p = 0.00097). Compared with common HCC (cHCC), SHHCC was associated with significantly higher mean triacylglyceride (p = 0.010) and diacylglyceride contents (p = 0.002) in tumor tissues. Fat fraction (FF) was linearly correlated with lipid composition and fatty acid degradation (FAD) subtype, which could help in treatment options for HCC. The univariate and multivariate logistic regression indicated FF (p < 0.001) as an independent predictor for diagnosing this phenotype. ROC analysis confirmed excellent discrimination (area under the curve (AUC), 0.914; sensitivity, 92.3%; specificity, 78.7.0%). After using the optimal cutoff point, the DFS time of patients with SHHCC stratified by FF was significantly higher than that of patients with cHCC.
Conclusion: The biological behavior and prognosis of HBV-SHHCC were better than those of other types. FF is a valuable tool for the clinical diagnosis of SHHCC, prognosis prediction, and treatment guidance in patients with HCC.
Key points: Question Can the diagnosis of steatohepatitic hepatocellular carcinoma (SHHCC) be made noninvasively? Findings Fat fraction (FF) correlated with lipid composition and could be used to diagnose SHHCC with an AUC of 0.914, sensitivity of 92.3%, and specificity of 78.7%. Clinical relevance MRI-based FF could be used to diagnose HBV-related SHHCC, indicate prognosis, and guide the clinical treatment of patients with HCC.
期刊介绍：
European Radiology (ER) continuously updates scientific knowledge in radiology by publication of strong original articles and state-of-the-art reviews written by leading radiologists. A well balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes ER an indispensable source for current information in this field.
This is the Journal of the European Society of Radiology, and the official journal of a number of societies.
From 2004-2008 supplements to European Radiology were published under its companion, European Radiology Supplements, ISSN 1613-3749.
