摘　　要：目的探讨钆塞酸二钠增强MRI动脉期不规则环形强化肝细胞癌(IRE-HCC)的病理学特征,分析其根治切除术后早期复发情况。资料与方法回顾性收集2015年2月—2021年9月在南通市第三人民医院就诊且经手术病理证实的HCC 131例。依据钆塞酸二钠增强MRI动脉期强化方式分为IRE-HCC和非IRE-HCC。比较两组患者的临床、病理及影像资料。采用Logistic回归分析与IRE-HCC相关的临床、病理与影像学特征,Kaplan-Meier法评估HCC术后2年内早期无复发生存率,Cox回归分析HCC术后早期复发的危险因素。结果CK19(OR=9.027,95%CI 2.533~32.170,P=0.001)、微血管侵犯(OR=3.606,95%CI 1.024~12.701,P=0.046)和扩散加权成像靶征(OR=10.370,95%CI 3.046~35.303,P=0.000)与IRE-HCC相关。IRE-HCC术后2年累积无复发生存率(24.1%)显著低于非IRE-HCC(55.9%,χ^(2)=19.971,P=0.000)。微血管侵犯(HR=2.206,95%CI1.152~4.226,P=0.017)和IRE(HR=2.454,95%CI 1.408~4.275,P=0.002)是HCC术后早期复发的独立预测指标。结论IREHCC与CK19、微血管侵犯和扩散加权成像靶征相关,且术后早期复发率高、预后差。Purpose To investigate the pathological characteristics of hepatocellular carcinoma(HCC)with irregular rim-like arterial phase enhancement(IRE)using gadoxetic acid-enhanced,and its early recurrence prognostic significance after surgery.Materials and Methods This retrospective study included 131 patients with surgically confirmed HCCs who underwent gadoxetic acid-enhanced MRI from February 2015 to September 2021 in the Third People's Hospital of Nantong.According to the enhancement pattern of gadoxetic acid-enhanced MRI in arterial phase,HCC were divided into IRE-HCC and non-IRE-HCC.Clinical,pathological and imaging characteristics were compared between IRE-HCC and non-IRE-HCC.Logistic regression analyses were performed to identify clinical,pathological and imaging features associated with IRE-HCC.Early recurrence(within 2 years)was evaluated by using Kaplan-Meier analysis.Cox regression analysis was performed to determine independent predictors of early recurrence.Results Cytokeratin 19(CK19)(OR=9.027,95%CI 2.533-32.170,P=0.001),microvascular invasion(OR=3.606,95%CI 1.024-12.701,P=0.046)and diffusion weighted imaging target signs(OR=10.370,95%CI 3.046-35.303,P=0.000)were independent predictors for IRE-HCC.The 2-year cumulative recurrence-free survival rate postoperative of IRE-HCC was 24.1%,which was significantly shorter than that of non-IRE-HCC(55.9%,χ^(2)=19.971,P=0.000).Microvascular invasion(HR=2.206,95%CI 1.152-4.226,P=0.017)and IRE(HR=2.454,95%CI 1.408-4.275,P=0.002)were independent predictors of early postoperative recurrence of HCC.Conclusion IRE-HCC are associated with CK19,microvascular invasion and diffusion weighted imaging target signs,and have a high recurrence rate and poor prognosis in the early postoperative period.
