[摘 要] 目的:比较乳腺 X 线摄影(mammography,MG)、超声(ultrasonography,US)和磁共振成像(magnetic resonance imag⁃
ing,MRI)3 种常规影像学检查在评估乳腺导管原位癌(ductal carcinoma in situ,DCIS)或 DCIS 伴微浸润(DCIS with microinva⁃
sion,DCIS⁃MI)病灶大小方面的效能,探讨其辅助临床管理保乳患者的潜在价值。方法:回顾性收集南京医科大学第一附属医
院病理证实的DCIS/DCIS⁃MI患者的病例资料,将3种影像学检查评估的病灶大小与“金标准”病理学大小比较,采用McNemar
检验和Bland⁃Altman法对不同成像方式进行准确性、一致性的评价。采用单因素与多因素分析明确影响评估准确性的临床病
理特征,并进行亚组分析。最后,探索分析导致影像学检查结果为假阴性的影响因素。结果:共入选263例DCIS/DCIS⁃MI 患
者。测量均值偏差方面,MRI多高估(+3.5 mm)病灶,而MG(-2.5 mm)和US(-1.4 mm)低估。一致性分析提示MRI与病理结果
相关性最强(r=0.853),95%一致性界限(95% limits of agreement,95% LOA)范围最窄(-1.73~2.44 cm),优于MG(r=0.561)及US(r=
0.614)。McNemar 准确性分析提示 MRI 准确性高于 US 和 MG(P < 0.05),而二者联合使用后准确性与 MRI 相当(P=0.921)。
Logistic 回归分析显示,确诊时年龄>60岁(OR=0.322)、肿瘤直径16~40 mm(OR=3.019)和≥41 mm(OR=6.146)显著影响MG评
估准确性(P < 0.05)。肿瘤直径16~40 mm(OR=2.270)和≥41 mm(OR=4.237)及导管扩张征(OR=1.728)显著增加US评估误差
风险(P < 0.05)。中重度乳腺背景实质强化(OR=2.139)和非肿块样强化灶(OR=2.655)显著增加 MRI 评估误差风险(P <
0.05)。亚组分析提示,肿瘤直径≤15 mm,3 种影像学检查评估效能相近;直径 16~40 mm,宜选择超声;直径≥41 mm,宜选择
MRI。此外,HER2表达状态(OR=0.100)及Ki67表达水平(OR=0.297)是影响MG检出病灶的独立预测因子(P < 0.05)。结论:
术前MRI检查有助于指导DCIS/DCIS⁃MI患者实现精准保乳,尤其病灶直径≥41 mm时。在基层医院的临床诊疗工作中,可推
行超声联合乳腺X线检查。对于HER2和Ki67低表达的患者,术前乳腺X线评估时应注意假阴性可能。

[Abstract] Objective:To compare the efficacy of three conventional imaging tests,mammography(MG),ultrasonography(US),and
magnetic resonance imaging(MRI),in assessing the lesion size of ductal carcinoma in situ(DCIS)or DCIS with microinvasion(DCIS⁃
MI),and explore their potential value in guiding breast ⁃ conserving surgery. Methods:We retrospectively collected case files of
patients with pathologically confirmed DCIS/DCIS⁃MI in our hospital,and compared the lesion sizes assessed by the three imaging
modalities with the“gold standard”pathological size,and evaluated the accuracy and consistency of the different imaging modalities
by using McNemar’s test and Bland⁃Altman’s method. Univariate and multivariate analyses were used to identify the clinicopathologic
features that influenced the accuracy of the assessment,followed by subgroup analyses. Finally,the influencing factors leading to false⁃
negative ⁃imaging results were explored and analyzed. Results:A total of 263 patients with DCIS/DCIS⁃MI were enrolled in this study.
Regarding the measurement mean deviation,MRI mostly overestimated(+3.5 mm)lesions,while MG(-2.5 mm)and US(-1.4 mm)
underestimated them. Consistency analysis suggested that MRI had the strongest correlation with pathological findings(r=0.853)and
