유방 병변의 초음파 유도하 중심생검: 2017년 의학적 감사

Abstract

Purpose: To determine the diagnostic accuracy, underestimation rate and false negative rate of sonographically guided core needle biopsy for breast lesions. Materials and Methods: We included 1,221 breast lesions from 1,073 patients who had undergone sonographically guided 14-gauge core needle biopsies between January 2017 and December 2017. The sonographic category of breast lesions and the pathologic results of core needle biopsies were reviewed and correlated with that of surgery or vacuum assisted biopsy, or >1yr follow-up. The positive predictive value for each category, sensitivity, underestimation rate and false negative rate of core needle biopsy were evaluated. Results: The positive predictive values for each sonographic category were as follows: 0% in category 2; 0% in category 3; 14.3% in category 4a; 51.5% in category 4b; 86.4% in category 4c and 99.0% in category 5. The sensitivity of core needle biopsy was 94.9% (462/487). The underestimation rate was 13.0% (23/177) for high-risk and 40.4% (37/94) for ductal carcinoma in situ. The false negative rate was 0.3% (2/581). Conclusion: Sonographically guided core needle biopsy for 2017 year in our hospital was accurate diagnostic tool for evaluating breast lesion.
