title: [Sentinel lymph node biopsy in breast neoplasms].
abstract: OBJECTIVE
  Sentinel node (SN) is the first draining node from the malignant tumor site. In the last decade, sentinel node biopsy (SNB) has been introduced as an alternative to axillary dissection in breast cancer. I n patients with negative SNB (sentinel node uninvolved with malignancy) axillary dissection is not recommended. The aim of this stady was defining the indications for SNB, and SNB principles, as well as the survey of our first experiences.
  
  
  METHODS
  In the period from 2004 to 2008, we performed 78 SNBs in 75 patients (72 females, 3 males) with breast cancer. Indications for SNB were T1-2 and N0 lesions according to TNM classification (Tumor, Nodus Methastasis). In all cases, lymphoscintigraphy was done first, and then SNB with double contrast (methylen blue and technetium - Tc-99). In 57 (73%) cases, one SN was confirmed, and in 21 (26.9%) 2 nodes.
  
  
  RESULTS
  In 58 (74.3%) SNB, SN pathohistology was negative, ie. there were no cancer metastases. In this group of patients, axillary dissection was not done in 47 (81%) SNB. In the remaining 11 (18.9%), lymphonodal dissection level I and II was done after SNB, regardless of the presence or no presence of metastases within SN. All the cases were monitored from six months to one year of the operation and disease progression was not observed.
  
  
  CONCLUSIONS
  Sentinel node biopsy is an acceptable method of breast cancer diagnosis and a good alternative to lymphonodal dissection if there are no metastases within SN. The technique is relatively simple, but requires team work of experienced specialists: surgeons, nuclear medicine specialists and anesthesiologists. Our first experiences suggest a high degree of reliability of the method in selected patients and with well trained team of doctors.
