Abstract

Background: We evaluated the usefulness of axillary ultrasound (US) in patients with core biopsy-proven ductal carcinoma in situ (DCIS).

Methods: Preoperative axillary US, fine-needle aspiration (FNA), and sentinel lymph node (SLN) data from women with DCIS were reviewed.

Results: Eighty-two women with DCIS underwent axillary US. In 16 women (19.5%) US was abnormal; however, FNA was negative in all cases. Sixty-one women (74%) underwent SLN surgery; 2 were positive for macrometastasis (3%) and 1 had isolated tumor cells. None of them had an abnormal US. Axillary US did not change the management in any of the cases.

Conclusions: Axillary US and FNA did not change the management in any of the 82 cases. In women with a core biopsy diagnosis of DCIS, positive nodes are uncommon and unlikely to be detected by axillary US. Routine preoperative axillary US is not recommended for pure DCIS on core biopsy.
