The absence of axillary re-staging could increase future local recurrence and mortality risk in these patients. The lymphoscintigraphy for sentinel lymph node biopsy in recurrences (rSLNB) using a radiotracer injection, can be an option to evaluate axillar status, but other factors known to alter the usual behaviour of SLN migration have to be taken into account, such as previous axillary surgery, breast surgery or adjuvant treatments. Our objective was to evaluate the relationship between these factors and the success rate of rSLNB (overall and aberrant drainage rates, metastases ratio).</p><p><strong>Materials and methods: </strong>1102 patients were retrospectively evaluated in a tertiary hospital between 10/2018-04/2022. 52 patients with ipsilateral breast tumor recurrence who underwent rSLNB were included.
