Ambulatory sentinel lymph node biopsy preceding neoadjuvant therapy in XXXX with operable @entity0 : a preliminary study.

@entity1 @entity0 @entity5 @entity1600 @entity3944
BACKGROUND: @entity1600 ( @entity1600 )-oriented stepwise treatment under local anesthesia has been performed in the outpatient-ambulatory setting in @entity1 receiving neoadjuvant therapy (NAT). We retrospectively reviewed our preliminary experience of ambulatory @entity1600 in @entity0 @entity1 scheduled to undergo NAT to evaluate the usefulness and feasibility of this method as a minimally invasive, stepwise treatment protocol. METHODS: We retrospectively identified 56 @entity1 with @entity0 without obvious nodal involvement who were scheduled to receive NAT before breast surgery. @entity1600 was performed under local anesthesia in an ambulatory outpatient setting before the initiation of NAT. RESULTS: The average number of removed sentinel lymph nodes was 1.9. Identification of the sentinel node was possible in all cases, and macrometastasis was observed in six cases (10.7%). @entity3944 was observed in five cases, while @entity5 cells were noted in six cases. There were no delays in the initiation of NAT as a result of complications of @entity1600 . CONCLUSIONS: This pilot study demonstrated the safety and feasibility of ambulatory @entity1600 prior to NAT. Further studies are warranted to assess the strict indications, @entity1 satisfaction, and medical economics of this procedure.
