Detecting of breast cancer metastasis by means of regional lymph node sampling during autologous breast reconstruction – a screening of 519 consecutive patients

Background The internal mammary artery and vein is often used as a site of anastomoses in microvascular breast reconstruction. This area supports lymphatic drainage of the breast and its role in breast cancer metastasis remains unclear. We hypothesize that sampling of internal mammary lymph nodes at the time of microvascular anastomoses preparation may identify persistent or recurrent local disease and mandate the need for additional treatment in this area.
