title: [Selective biopsy of the sentinel lymph node in breast cancer: without axillary recurrences after a mean follow-up of 4.5 years].
abstract: OBJECTIVE
  To analyze the rate of axillary recurrences (AR) in patients with early breast cancer who had not undergone an axillary node dissection (ALND) because of a negative sentinel lymph node biopsy (SLNB).
  
  
  METHODS
  The study includes 173 patients operated on for breast cancer and selective node biopsy. In 32 patients the SLNB was positive and undergone subsequent ALND. We followed up 141 patients with negative SLNB without LDN, with a median follow up of 55 months (range 74-36).
  
  
  RESULTS
  The detection rate of SLN was of 99.42%. After a median follow-up of 4.5 years, there were no axillary recurrences. Two patients developed local recurrence, other two patients developed distant metastases and four patients developed a metachronous tumor. Four patients died, none of them because of breast cancer.
  
  
  CONCLUSIONS
  The results obtained support the SLNB as an accurate technique in the axillary stratification of patients with breast cancer, offering in the cases of negative SLNB a safe axillary control after 4.5 year follow-up.
