BACKGROUND
Surgical decisions for ductal carcinoma in situ (DCIS) are based on lesion sizes. This study aims to determine the accuracy of pre-operative imaging in estimating the size of DCIS.
METHODS
This was a retrospective review of clinicopathologic data of patients treated for DCIS with breast conserving surgery (BCS) between 2012 and 2018. Mammographic and sonographic lesion sizes were compared with final pathology sizes.
RESULTS
For the 152 lesions visible on mammography, mean size on imaging was significantly smaller when compared to final pathology (2.3 vs. 3.6 cm, p < 0.001). The mean difference of 1.3 cm was a significant underestimation with a correlation coefficient of 0.367 (p < 0.001). For 48 sonographically visible lesions, the radiologic size was significantly smaller than pathologic size (1.7 vs. 4.1 cm, p < 0.001), but the degree of underestimation was not significantly correlated (p = 0.379).
CONCLUSION
DCIS size was significantly underestimated by imaging. This must be taken into consideration during surgical planning.
背景
导管原位癌（DCIS）的手术决策基于病变大小。本研究旨在确定术前影像学在估计 DCIS 大小方面的准确性。
方法
这是一项回顾性分析，对 2012 年至 2018 年间接受保乳手术（BCS）治疗的 DCIS 患者的临床病理数据进行了回顾。比较了乳腺 X 线摄影和超声检查的病变大小与最终病理大小。
结果
在 152 个可在乳腺 X 线摄影上看到的病变中，与最终病理学相比，影像学上的平均大小明显较小（2.3 厘米 vs. 3.6 厘米，p < 0.001）。平均差异 1.3 厘米是显著低估，相关系数为 0.367（p < 0.001）。在 48 个超声可见的病变中，放射学大小明显小于病理学大小（1.7 厘米 vs. 4.1 厘米，p < 0.001），但低估程度无显著相关性（p = 0.379）。
结论
影像学检查显著低估了 DCIS 的大小。在手术计划中必须考虑到这一点。
