Abstract
SummaryDuring 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.
Highlights
The overall increase in breast-conserving surgery of 13% reflected a decline in both uni- and bilateral mastectomy
The National Comprehensive Cancer Network (NCCN) Guidelines 2016 [7] recommend that if patient and physician perceive individual risk as being low, some ductal carcinoma in situ (DCIS) patients may be treated with excision only, without radiotherapy
King from Harvard Medical School talked about the consequences of neoadjuvant chemotherapy (NCT) on breast cancer surgery, allowing breast conservation and reduced need for axillary node dissection by downstaging of the disease
Summary
Received: 5 February 2017 / Accepted: 18 April 2017 / Published online: 7 June 2017. Summary During the San Antonio Breast Cancer Symposium in December 2016, the main topics were systemic treatment of breast cancer and molecular research. Several studies were 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. Preliminary data pointed out the trend in surgical treatment of breast cancer in the years 2013–2015 of a 16% decrease of additional surgery after lumpectomy due to a decrease in the proportion of patients with negative margins having re-excision. The overall increase in breast-conserving surgery of 13% reflected a decline in both uni- and bilateral mastectomy
