Forty-six patients with cirrhosis and 75 biopsy-proved hepatocellular
carcinoma (HCC) nodules underwent percutaneous ethanol injection (PEI)
regardless of number (up to five) and size (mean diameter, 3.6 cm) of
tumoral lesions and clinical severity of cirrhosis (11 patients in Child's
class C were included). Ethanol was injected under sonographic guidance
through 20 to 22 gauge needles so as to obtain homogeneous
hyperechogenicity of lesions. A total of 271 PEI sessions were carried out,
delivering 2 to 14 ml per session. All nodules but one decreased in size,
and seven were no longer appreciable on sonography. Recurrence was detected
in two patients. The 3 year survival rate of all cases was 86%. Child's
classes A and B patients fared better (3 yr survival 100%); 2 year survival
of subjects with HCC < or = 3 cm was 92%. Multifocality did not affect
survival. Most patients experienced mild pain at the site of injection, but
only two major complications were encountered: partial chemical thrombosis
of the left portal vein and cholangitis. Both cases were managed
conservatively. In conclusion, PEI seems to offer a safe and valuable tool
for therapy of HCC, especially in patients with good functional liver
reserve and small (< or = 3 cm) tumors.
