"In breast cancer, a combination of radioisotope and blue dye mapping maximizes the success and accuracy of sentinel node (SLN) biopsy. When multiple radioactive nodes are present, there is no single definition of isotope success, but the popular ''10% rule'' dictates removal of all SLN with counts > 10% of the most radioactive node," scientists in the United States report. "Here we determine how frequently a positive SLN would be missed by the 10% rule. Between 9/96 and 12/04, we performed 6,369 successful SLN biopsies using Tc-99m sulfur colloid and isosulfan blue dye, removing as SLN all radioactive and/or blue nodes, and taking counts from each node ex vivo....
