BREAST LYMPHATICS AND SENTINEL LYMPH NODE BIOPSY (Abstract): Highly variable, the lymphatic drainage of the breast is mainly directed to the axillary lymph nodes through a superficial and a deep system. The axillary lymph nodes are anatomically divided in five groups, whereas from a surgical point of view there are three different levels, in regard to the pectoralis minor muscle. In breast cancer one of the most powerful predictor of prognosis is the axillary lymph node status at surgery. Lately the sentinel node biopsy technique has replaced the axillary node dissection as gold standard in selected cases. There are numerous techniques that can be used to locate the sentinel lymph node, but in breast cancer the gold standard is considered the dual technique of blue dye and radioisotope injection. Controversy over the site of the tracer injection persists, but it appears that the peritumoral injection of the tracer would be optimal for the identification of the sentinel lymph node in breast cancer.
