Response to ‘Sentinel lymph node biopsy in melanoma: which hot nodes should be harvested and is blue dye really necessary?’

We read with great interest Ranson et als' recent publication, 'Sentinel lymph node biopsy in melanoma: which hot nodes should be harvested and is blue dye really necessary?'.1 This article retrospectively analysed 42 nodal basins in which greater than one node had been harvested, comparing the overall sensitivity of their blue dye and radiocolloid procedures with the sensitivity that might have be achieved had, theoretically, cold blue nodes been left in situ. They state that this approach could have resulted in a 5% reduction in the number of nodes harvested with no apparent change in sensitivity.
