Abstract
BACKGROUND
Hepatocellular carcinoma (HCC) is a malignant tumor with rich blood supply. The blood supply is closely related to its occurrence and development. Contrast-enhanced ultrasound (CEUS) can quantitatively analyze the microcirculation blood flow of HCC, indirectly reflect its pathological characteristics, evaluate the curative effect, and guide clinical treatment.
AIM
To investigate the characteristics of CEUS parameters of HCC residual lesions after transcatheter artery chemoembolization (TACE), and analyze their correlation with serum hypoxia inducible factor-1a (HIF-1a).
METHODS
Eighty-six HCC patients treated with TACE were selected as the subjects. They were divided into either a no residual lesion group (52 cases) or a residual lesion group (34 cases). All patients underwent CEUS within 3 d before treatment and 30 d after treatment. The following perfusion parameters were measured: Maximum intensity (IMAX), time to peak (TTP), rise time (RT), and washout time (WT). The levels of serum HIF-1a and vascular endothelial growth factor (VEGF) were measured by enzyme-linked immunosorbent assay. The changes of perfusion parameters, and serum HIF-1a and VEGF levels before and after treatment were compared between the two groups.
RESULTS
Before treatment, there was no significant difference in IMAX, RT, TTP, WT, or serum HIF-1a and VEGF between the two groups (P > 0.05). After treatment, the levels of serum HIF-1a and VEGF in the no residual lesion group were significantly lower than those before treatment (P < 0.05), and CEUS showed that there was no obvious perfusion in the lesions. In the residual lesion group, after treatment, the levels of serum HIF-1a and VEGF were significantly higher (P < 0.05), IMAX was significantly lower (P < 0.05), and RT, TTP, and WT were significantly longer than those before treatment (P < 0.05). After treatment, IMAX in the residual lesion group was positively correlated with the levels of HIF-1a (R2 = 0.74, P < 0.05), and TTP, RT, and WT were negatively correlated with the levels of HIF-1a (R2 = 0.56, 0.42, and 0.48, respectively; P < 0.05).
CONCLUSION
CEUS can directly reflect the changes of HCC perfusion after TACE treatment, and the perfusion parameters (IMAX, TTP, RT, and WT) of residual tissues have a good correlation with the levels of serum HIF-1a, which can provide a reference for the comprehensive evaluation of the curative effect of TACE.
