Abstract
Sentinel lymph node (SLN) biopsy procedure in patients with non-advanced breast cancer made it possible to considerably reduce the intensity of unfavourable after-eff ects connected with classical axillary lymphadenectomy. The presence of metastatic changes in SLN coexists in some patients with metastases to non-SLN. Depending on the size of the metastases detected in SLN, the above mentioned clinical situation may aff ect from 10–41% of cases. Therefore in about 3/5ths of patients with diagnosed SLN metastasis, histopathologi cal examination of removed axillary lymph nodes — within the radicalization of surgical treatment, will not reveal further changes. Presently available calculation devices (nomograms) for measuring the likelihood of metastases in non-SLN of the armpit make it possible to accurately determine the probability of their occurrence. They therefore simplify further therapeutic decisions.
