[Towards the standardization of sentinel lymph node analysis in women with breast cancer].

Abstract

Sentinel lymph node biopsy allows enhanced pathology through serial sections and immunohistochemical analysis of the retrieved node, with detection of micrometastases and isolated tumor cells not otherwise recognized. We present our experience with a simple, effective, pathology protocol requiring six couples of sections at three different sentinel lymph node levels. Additional micrometastases or ITC were diagnosed in 51/416 patients (14.6%).
