Background: Sentinel lymph node biopsy (SLNB) is a developing alternative to axillary
dissection and may prove to be accurate in the detection of micrometastases in lymph nodes
of breast cancer patients. Limited studies exist in the use of SLNB after neoadjuvant therapy.
This study was undertaken to determine the accuracy of SLNB after neoadjuvant
chemotherapy. Methods: Thirty-one patients with stage I or II breast cancer underwent SLNB
after neoadjuvant chemotherapy. Results: Lymphatic mapping was performed by …

Background The performance of sentinel lymph node biopsy (SLNB) after neoadjuvant
chemotherapy (NCT) was investigated in patients with locally advanced breast cancer
(LABC). Methods After NCT of 178 patients with cytology-proven axillary/supraclavicular
nodes metastasis at the time of diagnosis, SLNB using radioisotope was performed
including completion node dissection between 2008 and 2011. The detection rate,
sensitivity, false negative rate (FNR), negative predictive value (NPV) and accuracy of SLNB …
