Methylene blue staining method in the sentinel lymph node biopsy in 100 cases of early breast cancer / 国际外科学杂志

ABSTRACT

Objective To analysis the application value and the existing problems of sentinel lymph node biopsy in breast cancer surgery.Methods Pathological findings were retrospectively analysised in 100 female cases of breast cancer,who were diagnosed with early breast cancer and used blue dye in sentinel lymph node biopsy.Results Among 100 cases,92 cases were found SLNS,that the detected rate was 92％.Detected 217 sentinel lymph node,every case has 1 to 6 node,with the average of 2.4.Nintg-two cases were performed ALND.Among them,the SLNS negative detected 58 cases of ALN feminine,SLNS negative ALN detected positive 4 cases,30 cases of SLNS positive ALN positive detected.All of the patients did not appear allergic reaction.SLNB false positive rate of O,the false negative rate was 11.8％,sensitivity 88.3％,specific degree of 100％,the diagnostic coincidence rate was 95.7％.Conclusions Compared with the conventional axillary lymph node dissection,the sentinel lymph node biopsy has obvious advantages in early breast cancer surgery.For the cases of sentinel lymph node negative,there was no necessary to do the axillary lymph node dissection.
