title: [Selective biopsy of the sentinel ganglion in patients with breast cancer. Initial results].
abstract: BACKGROUND
  Sentinel-node biopsy is meant to excise the first-echelon node from a primary tumor, which is the one that most probably harbors early metastases.
  
  
  METHODS
  We report our results in 35 patients with breast cancer, using a radiotracer by peri-tumoral injection, pre-surgical scintigraphy and intraoperative mapping with a gamma probe.
  
  
  RESULTS
  The technical success rate was 97%, negative predictive value 95.2%, accuracy 97%, and added value to staging 40%.
  
  
  CONCLUSIONS
  Compared with the conventional lymph-node staging procedure for breast cancer, sentinel-node biopsy with pre-surgical scintigraphy seems a good practical choice.
