Pre-operative lymphoscintigram for axillary sentinel lymph node biopsy (SLNB) may not be required for successful SLNB. The 117 consecutive @entity1 who underwent SLNB had pre-operative lymphoscintigraphy. The operating surgeon was blinded to the results of the lymphoscintigram before SLNB. After SLNB was complete, the surgeon was unblinded to the results of the lymphoscintigram; re-exploration carried out if more nodes were predicted on the lymphoscintigram. 116 @entity1 (99%) had successful SLNB before unblinding. In 85 @entity1 (73%), operative findings corresponded with scintigraphic findings. In 26 @entity1 (22%), the lymphoscintigram predicted more sentinel nodes than had been found; further nodes were identified and excised in only 4 @entity1 (3%). None were positive for @entity5 . SLNB was successful in 99% of cases without pre-operative lymphoscintigraphy. Only 3% of @entity1 had further nodes identified as a result of the lymphoscintigram. Pre-operative lymphoscintigraphy does not improve the ability to perform axillary SLNB during @entity0 surgery.
