title: [Radio-guided occult lesion localization combined with sentinel node biopsy in women with breast cancer].
abstract: BACKGROUND
  The practice of intratumoral radiocolloid injection for sentinel node biopsy (SNB) allows localization of nonpalpable breast tumors in the same surgical intervention, using the technique known as radio-guided occult lesion localization (ROLL).
  
  
  METHODS
  We present our experience with the combined use of both techniques (SNB and ROLL). A total of 233 patients were retrospectively analyzed: 65 patients underwent ROLL and 168 patients underwent wire-guided localization (control group) as the excision modality. Both groups had comparable pathologic and radiologic features.
  
  
  RESULTS
  Complete excision of the lesion was achieved at the first attempt in only 169 patients. There were no significant differences among groups in surgical margin status (margins were adequate in 80% of ROLL patients vs 69.9% of non-ROLL patients) or in maximum specimen diameter (6.85 cm vs 6.52 cm, respectively).
  
  
  CONCLUSIONS
  We conclude that ROLL is an acceptable alternative to wire-guided localization in patients with nonpalpable breast tumors undergoing SNB, leading to easier lesion excision and greater patient comfort.
