Miami Breast Cancer Conference
Tumor Board Case 2: Frank Vicini, MD

A young woman with DCIS

The patient is a 45-year-old premenopausal woman with a 3 cm, grade 3 DCIS, which was excised with clear but very close margins (less than 1 mm). She has small breasts but wants breast conservation and is very concerned about cosmesis. What is your recommendation for local therapy?

She undergoes further excision and no more tumor is found.
How would you approach the axilla?

She undergoes a sentinel lymph node biopsy, which is negative.
Which systemic therapy would you recommend?


For the initial presentation, most of the respondents recommended radiation therapy without further surgery. This is consistent with data from the NSABP suggesting that as long as margins are clear, no further surgery is needed. Dr Vicini’s patient was sent for further surgery, primarily because of her young age. Most respondents would not use axillary staging in this patient, but this woman had a negative sentinel node biopsy. Most of the respondents recommended tamoxifen, which is what the patient received.
