ABSTRACT
Objective@#To analyze the diagnostic value of ultrasound guided 14 gauge coreneedle biopsy (US-CNB) in breast nodules.@*Methods@#We retrospectively analyzed the pathological results of US-CNB and surgical excision from 373 breast nodules in Peking University International Hospital from Sep 2016 to Nov 2018 to evaluate the accuracy of 14g US-CNB.@*Results@#A total of 349 patients(373 nodules)underwent US-CNB. US-CNB reported 282 benign lesions(75.6%, 282/373), 20 high-risklesions(5.4%, 20/373), and 71 malignant lesions(19.0%, 71/373). For 282 CNB reported benign lesions, the surgical pathology confirmed 235 lesions , 46 for high-risk lesions and 1 for malignant lesion with a concordancy of 83.3%(235/282)and the underestimation rate was 16.7%(47/282). US-CNB identified 20 high-risk lesions. According to surgical results, 15 were high-risk lesions and 5 were malignant lesions with a concordancy of 75% (15/20)and the underestimation rate was 25%(5/20). When it comes to malignant lesions, the excision results showed that 70 were malignant lesions and 1was high-risk lesion with a concordancy of 98.6%(70/71)and the overestimation rate was 1.4%(1/71). The concordance of the histological type , calculated for 50 invasive carcinomas, was 92% (46/50) with a kappa value of 0.77.The concordance of the histological grade could be calculated for 38 invasive ductal carcinomas with the Elston-Elllis Method . It was 89.5% (34/38) with a kappa value of 0.57.@*Conclusions@#The pathology result of 14gUS-CNB is in good consistency with surgical excision for breast benign and malignant lesions.
