Abstract：Objective To explore the imaging features of breast X-ray and CT imaging in differentiating G1 and G2/G3 breast lobulated tumors, and to compare the diagnostic ef?cacy of the two methods. Methods In this study, 80 cases of phyllodes tumor of breast con?rmed by operation and pathology in our hospital were collected. Among them, 45 cases of mammography and 40 cases of CT were evaluated according to the clinical, X-ray and CT features. Chi square test and receiver operating characteristic (ROC) curve were used to evaluate signi?cant features and diagnostic ef?cacy of the two imaging methods. Results When the diameter of the tumor on X-ray and CT was larger than 4 cm and 3.25 cm respectively, it indicated that the tumor was G2/G3 grade, P=0.025, P=0.05. High grade tumors were more likely to show deep lobulation or multi nodule fusion (P=0.004 and 0.046). The P values of boundary and uniformity of tumor on CT were 0.018 and 0.016, respectively. The area under the ROC curve of X-ray was 0.831 (sensitivity 74.2%, speci?city 85.7%), and CT was 0.834 (sensitivity 72.4%, speci?city 81.8%). Conclusion Both mammography and CT imaging have a certain value in the differentiation of benign and malignant breast phyllodes tumors and have similar ef?cacy. Choose any examination according to the patient’s condition, which can provide a preoperative reference for the selection of surgical options.
