Purpose: To evaluate retrospectively whether it is possible to predict the transarterial chemoembolization(TACE) result with the pre-TACE dynamic CT findings.
Materials and Methods: The dynamic CT findings of 33 patients with 35 nodular and 8 massive hepatocellular carcinoma(HCCs) who was taken follow up CT after TACE, were reviewed retrospectively.
After excluding the diffuse or infiltrative HCCs, the mass was classified into two groups of nodular and massive types. The size, location, degree of enhancement, pseudocapsule, portal vein(PV) thrombosis and arterioportal(AP) shunt were evaluated on the dynamic CT scans. The vascularity, multiple or parasitic blood supply, AP shunt and the possibility of superselection were considered on the angiography. After TACE, the pattern of lipiodol uptake and residual enhancing nodules were evaluated on the follow-up CT scans.
Results: The good TACE results could be obtained in 18 of 35 nodular HCCs with dynamic CT findings of small size(mean=2.94㎝), peripheral location, hyper-or iso-enhancement, and absence of PV thrombosis, with angiographic finding of possible superselection, but the pseudocapsule did not give important effect on the result. Most of the massive HCCs had poor TACE results.
Conclusion: The prediction of the TACE results of nodular and massive HCCs was possible with dynamic CT findings. If the good prognostic factors were not observed on the pre-TACE dynamic CT, the multiple TACE and/or combination therapy with percutaneous ethanol injection(PEI), surgical resection or others should be considered for the effective control of the HCCs. |
