Abstract

Traditionally, axillary dissection has been the best way to staging patients with breast cancer, nevertheless in the early stages (I and II), without palpable axillary nodes (NO) half will not have nodal metastasis and will have been unnecessarily exposed to the morbidity of the procedure. The sentinel node (SN) has showed to be a predictor of the histologic state of the other axillary nodes, its identification allows to adequate staging of NO breast cancer patients avoiding the axillary dissection. To get to know the SN value as predictor of axillary nodal metastasis. From 2000 to 2001, 62 patients in stages I and II of breast infiltrating ductal carcinoma NO, have been subject to lymphatic mapping and biopsy of the sentinel node with blue dye, the sentinel node was studied intraoperatively and, independently from the result, axillary dissection was practiced to all the patients. A sensitivity and specificity test of the SN as predictor of the histologic state of the other nodes was carried out. In 58/62 (93.5%) the SN was identified, 18/58 patients (31%) had nodal metastasis, only one patient showed false negative SN (92% sensitivity). With the procedure, 98% of the patients were appropriately typified by stages, the specific...Continue Reading
