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.
