Antineoplaston treatment for advanced hepatocellular carcinoma.

Antineoplaston A10 injection (antineoplaston A10 I) exhibited cystostatic growth inhibition of human hepatocellular carcinoma (HCC) cells in vitro and showed minimum adverse effects in a phase I clinical trial. Advanced HCC is hard to control because the potent anticancer drugs or embolizations easily induce hepatic failure. We review herein 2 cases of advanced HCC treated with antineoplaston A10 I. Both cases showed interesting responses to antineoplaston A10 I. One showed massive coagulation necrosis of tumors after intra-arterial infusion of antineoplaston A10 I and the other showed resolution of portal vein tumor thrombosis with systemic infusion of antineoplaston A10 I. The usefulness of anti-neoplaston A10 I in terminal staged HCC is discussed.
