ABSTRACT
Sentinel node biopsy, in breast cancer, is a promising surgical technique for predicting histological findings in the remaining axillary lymph nodes, especially in patients with clinically node-negative breast cancer. 80 patients with breast cancer were evaluated for enrollment in this study. For mapping procedure 32 patients underwent lymphoscintigraphy in combination with an injection of vital blue dye, while 48 utilized only vital dye. In all patients, after sentinel node (SLN) biopsy, a complete axillary dissection was performed. The mapping procedure was possible in 79 cases (98.7%). The SLNs were positive in 27 (34.1%), in 52 patients SLNs were negative and in 50 of these all axillary nodes were negative. There was concordance in 77/79 cases (97.4%). The false negative rate was 3.8% (2/52). The overall sensitivity of the SNL biopsy was 93.1% (27/29), with a negative predictive value of 96.1% (50/52). This study demonstrates that accurate SLN identification was obtained combining lymphoscintigraphy and blue dye. Moreover, each method requires a suitable learning curve. Further studies are needed to define an accurate patient selection and the most speedy and precise method for intraoperative histological examination of SLNs.
