Prospective controlled trial with antiestrogen drug tamoxifen in patients with unresectable hepatocellular carcinoma.

Clinical and experimental evidence indicates that estrogens are involved in the control of hepatocyte proliferation both in normal and in neoplastic conditions. Thirty-two cirrhotic patients with unresectable or otherwise untreatable hepatocellular carcinoma were allocated to receive either tamoxifen (30 mg/day) or no treatment. The patients in the two groups were matched for age, male/female ratio, Child-Pugh class, approximate tumor volume (US and CT scan), and etiology of the underlying cirrhosis. Survival of the tamoxifen-treated patients (life-table, Wilcoxon-Breslow) was significantly prolonged (P = 0.0038), with 35% (vs 0%) survival at 12 months. No difference was observed between males and females or between alcoholic and nonalcoholic cirrhosis. In 40% of tamoxifen-treated patients, the levels of alpha-fetoprotein declined. In conclusion, the antiestrogen tamoxifen appears to be effective in the palliative treatment of hepatocellular carcinoma. An initial decline in alpha-fetoprotein levels may represent an early favorable prognostic sign.
