Sentinel lymph node biopsy using CT lymphography in breast cancer

摘要

Background Sentinel lymph node biopsy (SLNB) is a standard surgical procedure for patients with early breast cancer. The combination of radioisotope (RI) and dye staining is the most accurate method for identification of sentinel lymph nodes (SLN). However, institutions without RI centers perform SLNB by blue dye alone. The identification rate with the dye method alone is inferior to the RI combination method. In our institution, the identification rate of SLNBs by the dye method alone was 95%. So we started this study of SLNB using computed tomographic lymphography (CTLG).
