目的观察肝内胆管癌(ICC)常规超声及超声造影(CEUS)特征与其表达Ki-67水平的相关性。方法回顾性分析77例经病理确诊的ICC患者,根据目标病灶Ki-67表达水平将其分为高表达组(Ki-67≥20%,n=53)及低表达组(Ki-675 cm ICC占比高于低表达组(66.04%vs.33.33%,P=0.007)。组间常规超声所见ICC形态、边界及内部回声表现差异均无统计学意义(P均>0.05)。CEUS中,高表达组ICC呈周边环状增强及增强后病灶范围较前增大者占比均高于低表达组(P均0.05)。病灶最大径>5 cm(OR=5.612,P=0.004)及周边环状增强(OR=3.880,P=0.025)为预测ICC高表达Ki-67的独立因子。结论ICC病灶最大径>5 cm、CEUS呈周边环状增强提示其可能高表达Ki-67,有助于临床制定治疗决策。
