Abstract:
BACKGROUND: The value of contrast-enhanced ultrasound (CEUS), shear wave elastography (SWE) and their combination in the diagnosis of benign and malignant breast lesions have not been systematically evaluated. This study aimed to evaluate the diagnostic value of CEUS combined with SWE in benign and malignant breast lesions. METHODS: We searched six electronic databases for literature to evaluate the value of CEUS combined with SWE in the diagnosis of benign and malignant breast lesions from inception to May 2023. Review Manager 5.4 (Cochrane), Meta-DiSc 1.4, and Stata 14.0 (StataCorp) were used for meta-analysis. The pooled sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and the area under the curve (AUC) were calculated to evaluate the diagnostic performance. RESULTS: Ultimately, 17 studies were analyzed including 1,962 lesions in total. The overall quality of the included literature was acceptable, and no significant publication bias was found among the included studies. The pooled diagnostic performance measures for CEUS were as follows: SEN: 0.86 [95% confidence interval (CI): 0.84-0.88], SPE: 0.78 (95% CI: 0.75-0.80), PLR: 4.10 (95% CI: 2.86-5.90), NLR: 0.20 (95% CI: 0.15-0.25), DOR: 23.68 (95% CI: 16.77-33.44), and AUC: 0.90 (95% CI: 0.87-0.93); while, for SWE, SEN: 0.83 (95% CI: 0.81-0.86), SPE: 0.81 (95% CI: 0.78-0.83), PLR: 4.36 (95% CI: 3.18-5.97), NLR: 0.22 (95% CI: 0.17-0.29), DOR: 23.13 (95% CI: 14.70-36.40), and AUC: 0.90 (95% CI: 0.87-0.92). The measures for the pooled diagnostic performance of CEUS combined with SWE were as follows: SEN: 0.92 (95% CI: 0.90-0.94), SPE: 0.87 (95% CI: 0.85-0.89), PLR: 7.10 (95% CI: 5.24-9.61), NLR: 0.11 (95% CI: 0.07-0.16), DOR: 83.51 (95% CI: 49.67-140.39), and AUC: 0.96 (95% CI: 0.94-0.98). There was no statistically significant difference in SEN, SPE, and accuracy (ACC) between CEUS and SWE (P>0.05), but they were significantly lower than those of CEUS combined with SWE (P<0.001). CONCLUSIONS: The diagnostic performance of CEUS combined with SWE is higher than that of using CEUS or SWE alone and can further improve the diagnosis of breast lesions.
