Abstract:
Objective To explore the diagnostic value of ultrasound guided core needle biopsy (CNB) and vacuum assisted biopsy (VAB) in minor breast lesions with diameter 0.6 to 1.0 cm.Methods Totally 7 730 cases of breast lesions examined by ultrasound guided minimally invasive biopsy were enrolled in Breast Cancer Prevention and Treatment Center of Peking University Cancer Hospital from April 2014 to May 2016.254 lesions with maximum diameter 0.6 to 1.0 cm in 243 cases were analysed retrospectively (232 unilateral &11 bilateral) and divided into group CNB(152 lesions) and group VAB (102 lesions).The accuracy of pathological diagnosis and the rate of breast conserving surgery were compared between the two groups.Results There were 94 non-malignant and 58 malignant breast lesions as initially diagnosed by CNB.Among those 94 tentative non-malignant lesions,33 underwent open surgical biopsy and 4 malignancies were finally established by pathology.In group CNB,the sensitivity was 93.4％,the specific was 100％,the accuracy was 97.4％.There were 91 non-malignant and 11 malignant lesions as initially diagnosed by VAB.In those with established malignant disease,the rate of breast conserving surgery between group CNB and group VAB was statistically different (62.9％ vs.27.3％,P =0.045).Conclusions Ultrasound guided core needle biopsy and vacuum assisted biopsy are with high accuracy for small breast lesions.The rate of breast conserving surgery for breast cancer is higher in group CNB patients by the different type of minimally invasive biopsy.
