“…In the few cases published in the literature [63,[68][69][70][78][79][80][81], in which AD was performed after an positive SLNB, in all cases but one (67/68, 98,5%) all the non-SLNs were negative and the SLN already biopsied was the only positive LN. That is why we conclude that in cases of DIN patients with a positive SLNB, AD should not be immediately performed except for only those cases that present mammary invasion on final pathologic evaluation.…”
