  • Value of Contrast-Enhanced Ultrasound in Differential Diagnosis of Preoperative Benign and Malignant Breast Mass: A Systematic Review

    ObjectiveTo systematically review the clinical value of the contrast-enhanced ultrasonic in the diagnosis of breast tumors. MethodsWe electronically and comprehensively searched the databases including The Cochrane Library (Issue 2, 2013), PubMed, CNKI, WanFang Data, Chaoxing medalink, VIP, and CBM for clinical research reports of diagnosing breast cancer with Contrast-enhance ultrasonic (all from foundation to May 2013). Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of the included studies according to the QUADAS items. The Meta-DiSc software (version 1.4) was used to conduct pooling on sensitivity, specificity, positive likelihood ratio, and negative likelihood ratio. Heterogeneity test was performed and the summary receiver operating characteristic (SROC) curve was drawn for area under the curve (AUC). ResultsA total of 19 studies involving 1 161 participants were included. The results of meta-analysis showed that, specificity, the pooled sensitivity, positive likelihood ratio, negative likelihood ratio and DOR were 0.79 (95%CI 0.75 to 0.82), 0.86 (95%CI 0.83 to 0.89), 3.92 (95%CI 2.77 to 6.56), 0.18 (95%CI 0.13 to 0.26), and 25.86 (95%CI 13.77 to 48.55), respectively. The AUC of the SROC curve was 0.917 0. ConclusionThe current evidence shows that contrast-enhanced ultrasonic has high sensitivity and specificity in the diagnosis of preoperative benign and malignant breast mass, which indicates that it could be used as a good method to diagnosing breast tumors.
