Sentinel lymph node biopsy in melanoma: which hot nodes should be harvested and is blue dye really necessary?,,✯✯✯

The '10% rule' has become widely accepted by surgeons performing sentinel lymph node biopsy (SLNB) for melanoma. The purpose of this study was to compare the '10% rule' with alternative node harvesting criteria. In particular, we were interested to see whether the use of blue dye had any impact on the sensitivity of the test and whether it is necessary to remove all hot nodes.
