Diagnostic performance based on MRI for preoperative of vessels encapsulating tumor clusters in hepatocellular carcinoma: a systematic review and meta-analysis
摘要
Vessels encapsulating tumor clusters (VETC) pattern is a unique pattern of vascular invasion that has been shown to be a poor prognostic factor for hepatocellular carcinoma (HCC). The purpose of this review and meta-analysis was to explore diagnostic performance between non-radiomics and radiomics model based on MRI for preoperative of vessels encapsulating tumor clusters (VETC) in hepatocellular carcinoma (HCC).
MethodsAll included articles were obtained from PubMed, Embase, Web of Science and Cochrane library as of September 30, 2024. The QUADAS-2 tool was used to assess methodological quality of eligible studies. The pooled data was using a mixed effects model within a 95% confidence interval (CI). Diagnostic performance was represented by summary receiver-operating characteristic curves and the area under the curve (AUC).
ResultsA total of 14 studies (10 non-radiomics and 6 radiomics) with 2961 HCC patients were included in this study. The pooled sensitivity and specificity of non radiomics model were 0.80 (95%CI:0.76–0.83) and 0.74(95%CI:0.69–0.78), with AUC of 0.84 (95%CI:0.80–0.87); whereas that of radiomics model was 0.88 (95%CI:0.83- 0.91) and 0.86 (95%CI:0.81–0.90) with AUC of 0.93 (95%CI:0.91–0.95).
ConclusionsRadiomics model performed better than non-radiomics model based on MRI in preoperative prediction of VETC-positive HCC, but there was heterogeneity between studies, which needs to be interpreted with caution.
