[Sentinel node biopsy, a step toward selective axillary dissection].

We studied sentinel lymph node detection in 69 patients with breast cancer. A sentinel node (SN) was detected in 58 patients (83%), and the pathological result was compared with the results of the axillary contents. We found a positive correlation of the pathological results of the SN in relation to the axillary contents in 96% in pT1 and pT2 tumors.
