ABSTRACT
AIM:
This study aims to explore the accuracy, specificity and laws of axillary lymph node metastasis predicted by sentinel lymph node biopsy (SLNB) by comparing axillary lymph node status via SLNB and axillary lymph node dissection (ALND) with nanocarbon as the tracer.METHODS:
Forty six patients were retrospectively analyzed. These patients underwent SLNB with nanocarbon as the tracer from March 2013 to April 2014.RESULTS:
Two hundred and forty six patients of sentinel lymph node (SLN) were successfully detected. Among these patients, 8 patients had 1 SLN (3.25%), 33 patients had 2 SLN (13.41%), 46 patients had 3 SLN (18.70%), 51 patients had 4 SLN (20.73%), 40 patients had 5 SLN (16.26%), 24 patients had 6 SLN (9.76%) and 24 patients had 7 or more SLN (9.76%). The SLNB success rate of nanocarbon staining in the 246 cases was 99.59%, accuracy rate was 97.06% and sensitivity was 93.22%. Furthermore, false negatives were found in four patients, and the false-negative rate was 6.78%. The number of lymph node metastasis in the SLNB and ALND of early-stage breast cancer was analyzed. When the number of SLN dissection was 1, 2, 3, 4, 5, 6 or 7, the coincidence rate of lymph node metastasis for SLNB and ALND was 80.00, 84.36, 78.57, 88.89, 90.48, 80.00, 73.68 and 78.36, respectively.CONCLUSION:
Sentinel lymph node biopsy performed using the nanocarbon staining method is simple, easy and reliable, and it can be used to predict the axillary status of breast cancer in the early stage.Key words
