Objectives: In this study, we aim to investigate the correlations of quantitative parameters of contrast-enhanced ultrasonography (CEUS) and Spalt-Like Transcription Factor 4 (Sall4)/Wnt/β-catenin signaling pathway with clinicopathological features and prognosis of patients with hepatocellular carcinoma (HCC).
Methods: The CEUS was performed to detect the liver function and the prognosis of patients. The expression of Sall4, WNT3a and β-catenin was evaluated using immunohistochemical staining. Sall4, WNT3a and β-catenin mRNA expression was measured by SYBR green qPCR assay.
Results: We found that the mRNA and protein expression of Sall4, WNT3a and β-catenin in the HCC tissues were significantly upregulated compared with the adjacent normal tissues. Upregulation of these proteins was associated with tumor differentiation, TNM stage, tumor size, vascular invasion and liver cirrhosis of HCC patients. In addition, we found that decreased time to peak and washout time and increased peak intensity and area under the curve of CEUS in the HCC were also correlated with TNM stage, tumor size and vascular invasion. Moreover, Sall4, WNT3a and β-catenin protein were significantly associated with the TTP, PI, AUC, and WOT.
Conclusion: This study suggests that quantitative parameters of CEUS and Sall4/Wnt/β-catenin signaling may be helpful for early diagnosis and prognosis prediction of HCC patients.
