Sentinel node role in breast cancer surgery.
Radical surgery of breast cancer includes lymphadenectomy of axilla as well as the dissection of the neoplastic tissue. However recently many works have raised doubts on the opportunity of performing routinary axillary dissection, which elevates morbidity risk, in absence of axillary metastases. However, unfortunately, information on axillary lymph node pathology, is not available with any other technique excluding complete dissection and istopathological examination. Sentinel node technique is a new methodology that consents evaluation of lymph node status in the operating theatre. It allows the surgeon to judge on the opportunity of carrying out the lymphadenectomy or not.
