OBJECTIVES: o investigate the presence of metastasis of the sentinel node and like alternative to the traditional methods (Radio pharmacy Tc 99 and colorant), METHODS: In 128 patients with diagnosis of breast cancer, we evaluated the presence of axillary lymphatic nodes. We used an ecoguide biopsy of the axillary lymphatic nodes, when they are seen by ultrasound, a minimal axillary nodes dissection. The results were compared with the standard axillary dissection. The histological diagnose of the primary tumor was made by ecoguide biopsy or estereotaxia biopsy. RESULTS: The axillary lymphatic nodes ecoguide biopsy identified 22 % of metastasic sentinel nodes. The minimal axillary nodes dissection was practiced in 55 % of the 66 operated patients, and was able to identify the metastasic sentinel nodes in 37 % patients. The ultrasound was able to identify subclinical lesions in 36 % of the cases. The biopsy samples was performed fundamentally in T1 and T2 tumors; when the ecoguide biopsy of axillary nodes identifies axillary metastasis, it identifies high risk patients, independently as large as its tumor, than they could benefit from an induction treatment. CONCLUSIONS: The breast surgeon would have to use the breast ultrasound for an integral evaluation of the patients. The ecoguide biopsy of the axillary lymphatic nodes and the minimal axillary nodes dissection could be methods for the determination of sentinel nodes, in more accessible way to public hospitals, avoiding the morbidity of a complete axillary dissection of the in small tumors.
