Abstract
ObjectiveTo evaluate our experience with preoperative localization of non-palpable breast lesions (NPBL) with the injection of a radiotracer, or radioguided occult lesion localization technique, and with localization of NPBL and sentinel node (SN) with a single injection of radiotracer, or SN and occult lesion localization technique. Material and methodsWe included NPBL in which excision was indicated during the period from January 2001 to December 2011. The radiotracer was injected under stereotactic or ultrasound guidance. Scintigraphy was carried out in all patients before surgery. The surgeon in the operating room had a hand-held gamma probe to locate the lesions in the breast and in the axilla. Intraoperative pathological examination of the SN was done to avoid reinterventions if there were indications for axillary lymphadenectomy. ResultsWe included 881 patients: 226 benign lesions were localized in patients with indications for lumpectomy and 655 malignant lesions in patients scheduled for breast conserving treatment. The detection rate of NPBL was 99.4%. Reoperations were reduced to 7.4%. ConclusionIn our experience, radioguided surgery of NPBL with radioguided occult lesion localization-SN and occult lesion localization is a quick and simple technique that allows tumor excision with adequate surgical margins and optimal cosmetic results, as well as SN biopsy during the same operation.
