摘要: 目的 探讨钆塞酸二钠增强MRI特征预测肝细胞癌(HCC)患者术后肿瘤复发的价值,为临床评估HCC术后复发风险提供客观影像学依据。方法 2022年6月~2025年6月我院收治的58例HCC患者均接受肝叶切除术,随访至2026年2月。术前行增强MR扫描,测量平扫、动脉期、门静脉期、移行期和肝胆期同一层面病灶与正常肝实质的信号强度,计算相对信号强度比(RIR)。采用免疫组化法检测肝组织细胞角蛋白 19(CK19)表达。采用多因素 Logistic 回归分析影响因素。结果 本组HCC患者术后肿瘤复发23例(39.7%);复发组基线异常凝血酶原、甲胎蛋白水平、肿瘤直径、肿瘤细胞低分化、CK19阳性和T2N0M0占比均显著高于或大于未复发组(P<0.05);复发组肿瘤MR增强扫描肝胆期RIR为(0.5±0.2),显著低于无复发组【(0.7±0.1),P<0.05】;多因素 Logistic 回归分析显示,异常凝血酶原、肿瘤细胞低分化、TNM分期、马赛克征和肝胆期瘤周低信号均为影响肝细胞癌术后肿瘤复发的独立危险因素,而肝胆期RIR为肝细胞癌术后复发的独立性保护因素(P<0.05)。结论 增强MRI特征联合血清和临床指标可帮助判断HCC患者术后肿瘤复发风险,为临床制定个体化的随访策略提供重要参考。

Abstract: Objective The aim of this study was to investigate magnetic resonance imaging (MRI) features impacting recurrence of tumor in patients with hepatocellular carcinoma (HCC) after hepatectomy. Methods 58 patients with HCC were encountered in our hospital between June 2022 and June 2025, and all underwent hepatectomy after gadoxetic acid disodium-enhanced MRI scan. Patients were followed-up until February 2026. Relative intensity ratio (RIR) was calculate based on MRI. Cytokeratin 19 (CK19) expression was detected by immunochemical staining. Multivariate Logistic regression analysis was applied to find impacting factors for tumor recurrence. Results By end of follow-up, intrahepatic tumor recurrence was found in 23 cases (39.7%) in our series; baseline serum protein induced by vitamin K absence or antagonist-II (PIVKA-II), alpha fetoprotein levels, diameters of tumors, poor histological differentiation, CK19 positive rate and percentage of T2N0M0 in tumor recurrence group were significantly higher or greater than in non-recurrence group (P<0.05); RIR at hepatobiliary phase was (0.5±0.2), much lower than [(0.7±0.1),P<0.05] in non-recurrence group; multivariate Logistic regression analysis showed that serum PIVKA-II, poor differentiation, TNM staging, mosaic pattern and peritumoral hypointensity at hepatobiliary phase were all the independent risk factors, while RIR at hepatobiliary phase was the independent protective factor(P<0.05) for tumor recurrence. Conclusion Gadoxetic acid disodium-enhanced MRI features in combination with clinical materials could help predict tumor recurrence in patients with HCC after hepatectomy, which might guide individualized surveillance strategies.
