[A case with hepatocellular carcinoma with complete remission due to gamma-IFN therapy]

A 65-year-old male was admitted to our hospital with the aim of closer examination of SOL in cirrhotic liver. By abdominal echography, CT and angiography etc., he was diagnosed as LC with multiple HCC, one in S5 about 2.0 cm, another in S1 about 5.0 cm in diameter, and other four small nodules in right lobe. We treated him with recombinant gamma-IFN at dose of 1.6 X 10(7) units/day for 5 consecutive days biweekly. Although until two months the tumours were gradually enlarged in size, then they became smaller, and at five months later after the beginning of gamma-IFN therapy the tumor stains in angiogram disappeared. Then we performed the surgical treatment. Both macro and microscopical findings of tumor specimens in S5, 2. 2 X 2.0 X 1.9 cm in size, showed complete necrotic tissue. Additionally the yellowish small tumor was found on surface of S8, and it was adenomatous hyperplasia histologically.
