Local therapies for breast cancer.

During the San Antonio Breast Cancer Symposium in December 2016, the main topics were systemic treatment of breast cancer and molecular research. But several studies were also presented concerning local therapy: Surgical issues on evaluating resection margins, management of ductal carcinoma in situ (DCIS), surgical challenges after neoadjuvant therapy related to assessment of response or treatment of axillary lymph nodes, and studies about outcome after breast reconstruction and radiation therapy were discussed. In this short review, oral presentations of these topics are summarized.
