Results of Sentinel Lymph Node Biopsy in Patients with Breast Cancer in 10-Year Own Material of the 4th Military Teaching Hospital with Polyclinic in Wrocław

Abstract

1. Marking the sentinel lymph node in breast cancer, based on the single visualisation method with the use of radioisotope, is a useful and effective technique. 2. The factor influencing the results of the sentinel lymph node biopsy (true positive and negative results and false negative result) was the number of the excised lymph nodes except for the sentinel lymph node. 3. Patients with estrogen receptor expression had often metastases to sentinel lymph node (145 cases - 56%). 4. The false negative rate, i.e. 5.5% in our material, is within the limits of acceptability given in the literature. 5. The sentinel lymph node biopsy performed by the experienced surgical team is a reliable diagnostic tool with a low complication rate.

Nanocarbon Tracer and Areola Injection Site Are Superior in the Sentinel Lymph Node Biopsy Procedure for Breast Cancer

“…However, some studies have shown that different tracers and injection sites significantly affect the detection of SLNs by SLNB. Although studies have compared the effects of different tracers or injection sites for SLNB, there is currently no research to investigate the combined use of tracers and injection sites [ 20 , 21 ]. Therefore, this study compares the effects of different tracers injected at different sites on the detection of SLNs, providing a reference for improving the detection success rate and accuracy of SLNB.…”
