↵* Blue nodes (evaluated only in resection specimens).
RA = radioactive; B = blue; −− = lymph node station negative for radioactivity by probe and by lymphoscintigraphy; ++ = lymph node station positive for radioactivity by probe and by lymphoscintigraphy; +− = lymph node station positive for radioactivity by probe and negative by lymphoscintigraphy (false negative); −+ = lymph node station negative for radioactivity by probe and positive by lymphoscintigraphy.
