Abstract:

Objective The purpose was to evaluate the value of superb microvascular imaging (SMI) for benign and malignant breast tumors by a meta-analysis. Methods We searched PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), WanFang, VIP for literature on the diagnosis of SMI for benign and malignant breast tumors from the time of building the database to September 20, 2022. Two researchers screened literature and extracted information based on inclusion and exclusion criteria. The Quality Assessment of Diagnostic Accuracy Studies-2 (QUADAS-2) tool was performed to assess the quality of the included primary literature, Review Manager 5.3 was conduted to plot the literature quality assessment chart, Stata 17.0 was used to calculate SMI for sensitivity (SEN), specificity (SPE), positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) of breast tumors. The area under the curve (AUC) was obtained by summary receiver operating characteristic (SROC) curve. Funnel plot was applicated to evaluate publication bias. Results Fifteen meta-analyses representing 1769 cases of breast tumor patients were included, with 1912 lesions (916 malignant nodules and 991 benign nodules). The results of the meta-analysis showed that the SEN, SPE, PLR, NLR, DOR and AUC of SROC curves for SMI in the assessment of breast lesions were 0.82 (95%CI 0.79 to 0.84), 0.87(95%CI 0.85 to 0.89), 6.58(95%CI 4.58 to 9.43), 0.19(95%CI 0.16 to 0.24), and 39.47(95%CI 27.18 to 57.31), 0.93(95%CI 0.90 to 0.95). Conclusion SMI has a high diagnostic accuracy in evaluating the differentiation of benign and malignant breast lesions.
