Sentinel lymph node biopsy in primary XXXX : trust the radiolabeled colloid method and avoid unnecessary procedures.

@entity1600 @entity0
BACKGROUND: With regard to the @entity1600 ( @entity1600 ) procedure in @entity0 , the study analyzed the impact of discrepancies between the number of clinically and histologically identified @entity1600 , the impact of removing additional non-hot/non-blue but clinically conspicuous @entity1600 ( @entity1600 ), and whether the application of blue dye for mapping is necessary. METHODS: We analyzed 391 @entity1600 procedures in which 928 @entity1600 were removed. In all cases, radiolabeled colloid and blue dye were used for @entity1600 mapping. RESULTS: In 60 cases (15.3%), additional @entity1600 that were not identified by the surgeon were found by histological examination. In 22 cases (5.3%), tissue which clinically resembled an @entity1600 but was histologically connective tissue, was removed. In 76 cases (19.4%), 133 non-hot/non-blue but clinically conspicuous @entity1600 were removed. These additionally removed @entity1600 , however, did not alter the axillary staging. In 50.8% of the cases (n = 471), the @entity1600 were marked only by radiolabeled colloid. In 27 cases (2.9%), the surgeon identified the @entity1600 through blue coloration alone; however, in all of the latter cases, these @entity1600 were not deciding for axillary staging. CONCLUSION: The mapping agents may accumulate in axillary tissue and mimic the existence of an @entity1600 . The radiolabeled colloid method alone gives excellent mapping results. The additional application of blue dye is avoidable. Exact surgical preparation enables removal of the @entity1600 only and avoids removal of @entity1600 -containing adjacent tissue. The removal of further clinically identifiable enlarged non-hot @entity1600 should only be done if there is strong suspicion of metastatic involvement.
