Application of sentinel lymph node biopsy by subareolar injection of blue dye in the treatment of breast carcinoma

Abstract

To probe into the feasibility and accuracy of sentinel lymph node biopsy by subareolar injection of blue dye in the treatment of early-stage breast carcinoma. Retrospective analysis of 25 cases of early-stage breast cancer who were carried out subareolar injection of blue dye method for sentinel lymph node biopsy. Of 25 cases, 24 were checked out sentinel lymph nodes. Check-out rate was 96.0%. Totally 62 sentinel lymph nodes were checked out, each patient had 2.5 nodes averagely. There were 5 cases with lymph node metastases in HE stain, and 7 cases with positive nodes in IHC stain. Sensitivity in this group was 87.5%; Accuracy 96.0%; False negative rate 12.5%; False positive rate 0. Application of sentinel lymph node biopsy by subareolar injection of blue dye in the treatment of early-stage breast carcinoma can also acquire high check-out rate and high accuracy.
