    Abstract:
    For the treatment of small hepatocellular carcinoma, intratumor injection of absolute ethanol under ultrasound guidance was performed in 27 tumors in 23 patients, with a tumor diameter of between 1.0 and 3.3 cm. The initially elevated serum alpha-fetoprotein levels in 15 patients decreased during treatment, with 13 returning to normal after this regimen. In the 6 patients who finally received surgical resection, 4 had complete necrosis of the tumor, while the other 2 had a small peripheral residual cancer nest. In the remaining non-resected 17 cases, follow-up CT, multiple biopsies and angiography revealed evidence of viable tumor in only 3 cases. After additional ethanol injections, these 3 cases were successfully treated. Inhomogeneous distribution of the injected ethanol and difficulty in identifying the tumor after previous injections accounted for the incomplete necrosis of the tumor. To cope with these problems, a steel coil was implanted in the tumor before treatment, and a needle with multiple side holes was used in the last 3 cases, with satisfactory results. Ethanol injection is promising and may even be curative in the treatment of small hepatocellular carcinoma.
