Conclusion
- It would be useful to identify the pre-operative factors that could predict the presence of occult invasion within DCIS lesions. The ability to identify patients pre-operatively who have a high possibility of having a co-existing invasive carcinoma might allow sentinel lymph node mapping and needle aspiration or a biopsy to be performed prior to the initial surgical excision.
- In conclusion, the rate of underestimating DCIS for the use of a US-14G-CNB of breast masses in this study was 30.4%. Based on our results, it would seem difficult for radiologists to predict a possible pathologic underestimation by relying on the imaging and clinical findings of the breast lesion. However, the presence of abnormal axillary lymph nodes on US may be a useful factor to predict DCIS underestimation using a US-14G-CNB.
