Abstract：Objective To explore the diagnostic value and influencing factors of preoperative ultrasound and mammography BI-RADS classification in the early-stage breast cancer.Methods The clinical data on 43 patients with 44 breast lesions diagnosed as early stage (TNM Ⅰ-Ⅱ) breast cancer between August 2015 and August 2017 was retrospectively analyzed. All the patients received breast ultrasound and mammography examination and their BI-RADS classification before surgery was recorded. According to BI-RADS classification, the imaging Results were divided into three types: benign(≤3), suspicious for malignancy (=4a), and malignant (≥4b).The diagnostic value of ultrasound combined with mammography BI-RADS in a variety of breast cancers was explored and the influencing factors were analyzed.Results The proportion of cases that were suspicious for malignancy or malignant according to preoperative ultrasound BI-RADS classification of early stage breast cancer was 93.2%(41/44), which was significantly higher than that of mammography 75% (33/44)(P< 0.05). However, no significant difference were found between detection with ultrasound alone and that with the combined method (95%(42/44)). For mucous adenocarcinoma, the proportion of cases diagnosed as suspicious for malignancy or malignant with ultrasound was higher than with mammography, but there was no significant difference in BI-RADS classification of infiltrating ductal carcinoma, intra-ductal carcinoma and other types of breast cancer. The two lesions diagnosed as benign with the combined method were intra-ductal carcinoma and medullary carcinoma respectively.Conclusions For early-stage breast cancer and mucous adenocarcinoma in particular, the proportion of cases diagnosed as suspicious for malignancy or malignant with ultrasound was higher than with mammography during preoperative ultrasound BI-RADS classification.The proportion of cases diagnosed as suspicious for malignancy or malignant with ultrasound or mammography is closely related to the pathologic types, but there is still the possibility that the combined method fails to detect some special types of early-stage breast cancer and intra-ductal carcinoma.
