Can interpectoral nodes be sentinel nodes?
1Department of Surgery and Pathology, UMDNJ New Jersey Medical School, Newark, USA.
Background:
This study was designed to determine if interpectoral nodes could be sentinel nodes for some breast cancers.
Methods:
Thirty-five consecutive breast cancer patients undergoing axillary node dissection had a dissection of the interpectoral nodes. These were sent to pathology as a separate specimen.
Results:
Three patients were identified with isolated interpectoral nodal metastasis.
Conclusion:
In upper quadrants or deep breast cancers the interpectoral nodes may be the earliest site of nodal metastasis. This may lead to false negative results in some sentinel node biopsies.
