摘　　要：目的 探讨超声造影(CEUS)特征预测乳腺癌分子分型的价值。资料与方法 回顾性分析2020年1月—2022年7月于内蒙古医科大学附属医院术前行乳腺肿块常规超声检查及CEUS,术后病理诊断为乳腺癌,并获得免疫组化结果的122例患者,根据免疫组化结果分为Luminal A、Luminal B、人表皮生长因子受体-2(HER-2)过表达型及三阴性(TNBC)乳腺癌,分析不同分子分型乳腺癌CEUS特征及参数的差异。结果 不同分子分型乳腺癌患者年龄、Ki-67表达量差异有统计学意义(F=12.856,χ^(2)=211.370,P均<0.05),HER-2型平均年龄最大,Luminal B型、TNBC型以Ki-67占比更高多见。CEUS特征提示,Luminal A型、Luminal B型增强程度呈高增强、等或低增强分别为17例、15例,28例、27例,HER-2型、TNBC型高增强(16例、12例)占比更高(χ^(2)=3.235,P=0.039);灌注峰值时边界Luminal A型、Luminal B型、HER-2型以不清晰为主(17例、31例、16例),TNBC型以清晰为主(13例);HER-2型以灌注缺损(14例)和周围穿支血流(11例)多见,Luminal A型、Luminal B型以周围汇聚征(24例、41例)多见。时间-强度曲线参数:不同分子分型乳腺癌ΔPeak、ΔAUC差异有统计学意义(H=12.558、22.683,P均<0.05),其中HER-2过表达型ΔPeak和ΔAUC均高于其他亚型(P<0.05),可作为HER-2过表达型的预测指标,而不同分子分型乳腺癌ΔTP、ΔSharpness差异均无统计学意义(P>0.05)。结论 不同分子分型乳腺癌CEUS具有一定特征性,CEUS典型图像特征可协助鉴别乳腺癌的分子分型。Purpose To investigate the value of contrast-enhanced ultrasonography(CEUS)features in differentiating molecular subtypes of breast cancer.Materials and Methods The clinical data of 122 patients who underwent routine ultrasound examination and CEUS of breast mass before surgery and were pathologically diagnosed as breast cancer after surgery and whose immunohistochemical results were obtained in the Affiliated Hospital of Inner Mongolia Medical University from January 2020 to July 2022 were retrospectively analyzed,all patients were divided into Luminal A,Luminal B,HER-2 overexpression and triple negative breast cancers(TNBC)groups.The characteristics and parameters of CEUS among different molecular types of breast cancer were analyzed.Results The average age and expression of Ki-67 were significantly different in different molecular subtypes of breast cancer(F=12.856,χ^(2)=211.370,P<0.05).The average age of HER-2 was the oldest,and Ki-67 was more common in Luminal B and TNBC subtypes.CEUS characteristics indicated that Luminal A and Luminal B had high,equal,or low enhancement in 17,15,28,and 27 cases,respectively,while HER-2 and TNBC had a higher proportion of high enhancement(16,12)(χ^(2)=3.235,P=0.039).At the peak of perfusion,Luminal A,Luminal B,HER-2 were mainly unclear(15 cases,24 cases,16 cases),and TNBC was mainly clear(13 cases).HER-2 type was characterized by perfusion defect(14 cases)and peripheral perforator blood flow(11 cases),while Luminal A and Luminal B were characterized by peripheral convergence(24 cases,41 cases).Time-intensity curve parameters showed that were significant differences inΔPeak andΔAUC among different molecular types of breast cancer(H=12.558,22.683,P<0.05),ΔPeak andΔAUC of HER-2 overexpression type were higher than those of other subtypes(P<0.05),which could be used as predictors of HER-2 overexpression type,while there was no statistical significance inΔTP andΔSharpness of different molecular types of breast cancer(P>0.05).Conclusion There may be some characteristics i
