Abstract:
Objective To investigate the role of additional post core biopsy ultrasound in clinically node negative breast cancer.Methods Axillary ultrasound was performed before and after breast cancer was diagnosed on core biopsy samples.Post core biopsy ultrasound were performed by radiologists of this department of ultrasound at random.Post-diagnosis ultrasounds were performed by a radiologist with over 20 years of experience for the diagnosis of breast cancer with axi[lary disease.Results were compared to the final axillary pathological result.Results Of the 96 patients,17 were pathology lymph node positive.Post biopsy ultrasound identified 8 of the 17 positive nodes,with a sensitivity 47.1％,specificity 88.6％,positive predictive value of 47.1％,negative predictive value of 88.6％,accuracy of 81.3％.While the diagnosis index of pre-biopsy ultrasound were 47.1 ％,88.6％,47.1％,88.6％,81.3％,respectively.Conclusions Post-biopsy ultrasounds had an increased sensitivity for identifying positive axillary nodes,at the same times,specificity decreased.
