Abstract
AIM
To evaluate the blood perfusion status of residual hepatocellular carcinoma (HCC) tumors after transcatheter arterial chemoembolization (TACE) by contrast-enhanced ultrasound (CEUS) as well as the application value of CEUS.
METHODS
A total of 45 HCC patients with a total of 57 tumors who underwent TACE at our hospital were selected. CEUS was performed one day before treatment and one month after treatment. The blood perfusion parameters of residual tumors before and after TACE were compared.
RESULTS
The sensitivity, accuracy, and specificity of CEUS in the diagnosis of residual HCC lesions were 95.45%, 94.74%, and 92.31%, respectively. The enhanced intensity (56.87% ± 4.15%) of residual HCC tumors after TACE decreased significantly compared with that (75.09% ± 6.42%) before TACE (P < 0.05). The peak time (25.26 s ± 3.83 s) of HCC residual tumors after TACE was significantly longer than that (21.02 s ± 3.70 s) before TACE (P < 0.05). The area under the curve (581.29 ± 86.43) for residual HCC tumors decreased significantly compared with that (1017.83 ± 111.76) before TACE (P < 0.05).
CONCLUSION
CEUS can directly reflect the residual state of HCC after TACE and quantitatively evaluate the blood perfusion change of residual tumors, which can provide hemodynamic information for further clinical treatment.
