OBJECTIVE: To explore the discriminatory diagnostic value of multimodal ultrasound(US) combined with blood cell analysis(BCA) for Granulomatous Lobular Mastitis (GLM) and Invasive Ductal Carcinoma(IDC) of the breast.

METHODS: A total of 157 breast disease patients were collected and divided into two groups based on postoperative pathological results: the GLM group(57 cases with 57 lesions) and the IDC group(100 cases with 100 lesions). Differences in multimodal ultrasound features and the presence of BCA were compared between the two groups. The receiver operating characteristic(ROC) curve was used to calculate the optimal cutoff values, sensitivity, specificity, 95% confidence interval(CI), and the area under the curve(AUC) for patient age, lesion size, lesion resistive index(RI), and white blood cell(WBC) count in BCA. Sensitivity, specificity, positive predictive value, negative predictive value, diagnostic accuracy, and AUC were calculated for different diagnostic methods.

RESULTS: There were statistically significant differences(P < 0.05) observed between GIM and IDC patients in terms of age, breast pain, the factors in Conventional US(lesion size, RI, nipple delineation, solitary/multiple lesions, margin, liquefaction area, growth direction, microcalcifications, posterior echogenicity and abnormal axillary lymph nodes), the factors in CEUS(contrast agent enhancement intensity, enhancement pattern, enhancement range, and crab-like enhancement) and the factors in BCA(white blood cells, neutrophils, lymphocytes and monocytes). ROC curve analysis results showed that the optimal cutoff values for distinguishing GLM from IDC were 40.5 years for age, 7.15 cm for lesion size, 0.655 for lesion RI, and 10.525*109/L for white blood cells. The diagnostic accuracy of conventional US combined with CEUS(US-CEUS) was the highest(97.45%). The diagnostic performance AUCs for US-CEUS, CEUS, and US were 0.965, 0.921 and 0.832, respectively.

CONCLUSION: Multifactorial analysis of multimodal ultrasound features and BCA had high clinical application value in the differential diagnosis of GLM and IDC.
