Abstract:

Objective To explore the value of X⁃ray reevaluation of breast masses with depth⁃width ratio > 1（D/W > 1）and further analyze the clinical and ultrasound features of benign and malignant breast masses with D/W > 1. Methods A total of 317 breast lesions with D/W>1 by ultrasound were included in the study. These lesions were reevaluated by X ⁃ ray and classified by BI ⁃RADS further. According to different principles of clinical treatment，the lesions with BI⁃RADS 1⁃3 categories were evaluated as benign，and the lesions with BI⁃RADS 4⁃5 categories were evaluated as malignant. The diagnostic accuracy of X⁃ray reevaluation was calculated according to the gold standard of pathological results. The clinical and ultrasonic features of the benign and malignant breast masses were analyzed as well. Results Of the 317 cases，221 were diagnosed as malignant and 96 as benign. The diagnostic accuracy after X⁃ray reevaluation was more significantly improved than that only with ultrasound（P < 0.05）. In the clinical data，the age of patients with malignant tumors and the size of tumor in them were significantly larger than that with benign tumors（P < 0.05）. Meanwhile，when the ultrasonic features of D/W > 1 were excluded，there were significant differences between the benign and malignant tumors in terms of shape，edge，internal echo，posterior echo，microcalcification，blood flow，axillary lymph node enlargement（P < 0.05）. Conclusion Some benign lesions with D/W > 1 diagnosed as malignant initially by ultrasound are characterized by small volume and few other suspi⁃ cious ultrasound features. Combined with X⁃ray examination for reevaluation，the diagnostic accuracy can be greatly improved，and the incidence of invasive examinations such as puncture or operation can be reduced effectively.
