Clinical Value of Ultrasound-Guided Needle Biopsy in Differential Diagnosis of Benign and Malignant Beast Masses
Objective:To analyze the value of ultrasound-guided needle biopsy(us-cnb)in the diagnosis of benign and malignant breast masses.Methods:80 patients with breast masses treated in our hospital from April 2022 to March 2024 were selected and underwent us-cnb examination.Taking the pathological examination of mass resection as the"gold standard",the utility of us-cnb in differentiating benign and malignant breast masses was analyzed;In addition,the ultrasound images of breast masses with different properties were compared.Results:Among 80 patients with breast masses,48 cases were malignant and 32 cases were benign according to the"gold standard";A total of 47 malignant cases were detected by us-cnb;The sensitivity,accuracy,specificity,negative predictive value,and positive predictive value of us-cnb in the diagnosis of benign and malignant breast masses were＞90％based on the results of pathological examination of tumor resection as the"gold standard";Kappa test showed that:the consistency between us-cnb and the"gold standard"was excellent(kappa value=0.922,P=0.000);the proportion of irregular shape of malignant breast masses was 75.00％(36/48),the proportion of blurred edges was 83.33％(40/48),the proportion of uneven internal echo distribution was 72.92％(35/48),the proportion of aspect ratio＞1 was 85.42％(41/48),the proportion of lateral and posterior acoustic shadow was 68.75％(33/48),which was higher than that of benign breast masses 21.88％(7/32),37.50％(12/32),28.12％(9/32),31.25％(10/32)25.00％(8/32),the difference was statistically significant(P＜0.05).Conclusion:Us-cnb can effectively diagnose the benign and malignant breast masses,and there are significant differences in the ultrasonic image characteristics of breast masses with different properties.
