Sentinel lymph node detection through radioguided surgery in patients with breast cancer

Biopsy of the sentinel lymphnode (SLNB), the first lymphnode to receive lymphatic drainage from the primary tumor, accurately predicts the axillary lymph node status and, when negative, obviates the need for axillary lymphadenectomy (AL). The aim of this study was, to verify the SLN localization in breast cancer through preoperative lymphoscintigraphy and intraoperative gamma-probe, as well as to demonstrate the benefits of such techniques in preventing complications of AL. Medical records of 228 patients with breast carcinoma, who were underwent SLN localization and, radioguided surgery, from March 2005 to December 2007 were analyzed retrospectively. Data regarding age, tumor characteristic, breast involved, type of surgery, radiopharmaceutical drainage pattern, axillary assessment (SLNB or AL) and number of lymph nodes dissected were collected. It was ascertained that radioguided surgery is a selective method of axillary assessment in breast cancer, which makes this technique a safe alternative to radical assessment of total dissection of axillary lymph nodes and its subsequent complications.
