Abstract:
PurposeTo explore the application of ultrasonography-guided core needle biopsy (US-CNB) in diagnosis of breast phyllodes tumor, in order to provide a reliable basis for operation selection, and to improve prognosis.Materials and MethodsFifty-seven patients with diagnosed or suspected phyllodes tumor of the breast (PTB) were retrospectively studied. Ultrasound results and US-CNB biopsy data were compared with surgical pathology results.ResultsFor all the 57 cases of PTB, US-CNB revealed 46 benign cases, 8 cases of suspected borderline PTB, and 3 cases of mesenchymal malignant tumors. The postoperative pathological diagnosis of all the patients included 48 cases of benign tumors, 6 cases of borderline tumors, and 3 cases of malignant tumors. Compared with the postoperative pathology, US-CNB had sensitivity of 95.83%, speciifcity of 100.00%, the coincidence rate of 96.49%, the misdiagnosis rate of 4.17%, and misdiagnosis rate of 0%. The Youden's index was 0.96, andKappa was 0.8345. ConclusionUS-CNB has high sensitivity, speciifcity and coincidence rate in diagnosis of PTB.
