Diagnostic value of automated breast volume scanner in breast lesions / 中华健康管理学杂志

ABSTRACT

Objective To evaluate the diagnostic features, characteristics, value, and clinical significance of the automated breast volume scanner (ABVS) in breast lesions. Methods A total of 288 patients with breast lesions diagnosed at the Breast Surgery Department of Peking Union Medical College Hospital between 2011 and 2015 were selected. Diagnostic and image data of preoperative ABVS examinations, hand-held breast ultrasound (HHUS), and surgery or biopsy pathology were collected. Pathology and imaging report results were recorded, accounting for the retraction phenomenon; receiver operating characteristic(ROC)curve analysis was used to calculate the diagnostic performance of the single and combined diagnostic methods. Results (1) A total of 311 breast lesions were found in 288 patients using the ABVS;histopathological diagnosis showed that there were 141(45.3%)malignant lesions and 170 (54.7%)benign lesions.(2)The detection rates of the retraction phenomenon using the ABVS in malignant and benign lesions were, respectively, 31.2% (44/141) and 1.8% (3/170); the difference was statistically significant (χ2=52.075,P=0.000). The detection rates of the retraction phenomenon using the ABVS in invasive ductal carcinoma (IDC), ductal carcinoma in situ (DCIS), and other types of carcinomas were, respectively, 38.5% (40/104), 10.5% (2/19), and 11.1% (2/18). There were significant differences between IDC and DCIS and between IDC and other types of carcinomas (χ2=5.575, P=0.018; χ2=5.085, P=0.024, respectively). (3) The sensitivity, specificity, and accuracy rates of single ABVS were 89.4%, 80.6%, and 90.1%,respectively,and those of single HHUS were 91.5%,74.1%,and 91.3%,respectively,for malignant lesion diagnosis. For diagnosis with combined ABVS with HHUS, the sensitivity, specificity, and accuracy rates were 93.6%,72.9%,and 93.2%,respectively.Sensitivity and specificity rates,and the advantage ratio of the retraction phenomenon were, 31.2%, 98.2%, and 25.251, respectively. Conclusions Use of the ABVS for coronary sections with the retraction phenomenon has important clinical value in identifying malignant breast lesions,especially in identifying IDC,but ABVS cannot completely replace HHUS.ABVS combined with HHUS can improve the diagnostic capacity, and is helpful for early diagnosis of malignant breast lesions.
