Combined Transcatheter Arterial Chemoembolization and Percutaneous Ethanol Injection for Treatment of Hepatocellular Carcinoma: Preliminary Study
Abstract
- PURPOSE
Transcatheter arterial chemoembolization (TACE) and subsequent percutaneous ethanol injection
(PEi) was attempted in 8 patients with 9 hepatocellular carcinomas (HCCs) for complete tumor necrosis of HCCs
less than 5cm in greatest diameter.
MATERIALS AND METHODS
PEI was performed with 2-8ml of absolute (99.9%) ethanol two weeks after
TACE under CT or ultrasound guidance. For each patient PEI was done twice to four times within 4-10 days of
each procedure. After completion of a series of PEI, follow up examination (range:3 months-l.5 year period)
was done with angiography, CT or ultrasound and correlated with serum alpha-fetoprotein (AFP) level.
RESULTS
On follow up anglograms, the lesions completely disappeared or decreased in size without tumor
vessels or staining in 5 of 6 patients. On follow up CT of 6 patients, the lipiodol-laden HCCs were surrounded
by non-enhancing low density and the losion sizes were slightly decreased or not changed. These are
suggestive of necrosis of tumor itself and adjacent liver parenchyma. The tumors could not be detected on follow up
ultrasound examination in 2 patients. Serum AFP was decreased in 7 patients and was well corresponded to
the results of imaging modalities.
CONCLUSION
The authors concluded that the combined TACE and PEI is an appropriate treatment for small
HCCs having high surgical risks.
