Value of ultrasound interventional biopsy in diagnosis of phyllode tumors of breast

Objective To investigate the diagnostic value of interventional ultrasound biopsy for phyllode tumor of breast (PTB). Methods Forty-eight female patients with PTB diagnosed by surgical pathological examination from April 2016 to June 2018 in Datong Coal Mine General Hospital were selected. Forty-eight patients were 30 to 65 years old, 36 cases were benign PTB, 7 cases were borderline, and 5 cases were malignant. The ultrasound imaging manifestations of patients were analyzed, and the accuracy between the results of ultrasound interventional biopsy and surgical pathological diagnosis were calculated. Results The accuracy of ultrasound interventional biopsy in the diagnosis of PTB was 95.83% (46/48), and the proportions of benign, borderline, and malignant diagnostis of PTB were 34/36 (94.44%), 7/7, and 5/5. The ultrasound images of 34 patients with benign PTB and 9 patients with bordering PTB showed lobulated tumors, major diameter <5.0 cm, solid internal echo, clear edges, no or small blood flow signals, and 5 patients with PTB malignant tumors were round or oval, with a length of ≥5.0 cm, the internal echos were cystic, the edges were blurred, and the blood flow signals were abundant. Conclusions Ultrasound interventional biopsy has high accuracy in the diagnosis of PTB, and can provide imaging information such as location, long diameter, and morphology of tumor, and can provide basis for subsequent surgical treatment.
