Flutamide is an antiandrogen and frequently used for the treatment of
metastasized prostatic cancer. It is predominantly combined with an LH
-RH-analog. Severe hepatotoxicity occurs in few patients but may be fa
tal. We report on two patients with metastatic prostate cancer who rec
eived flutamide and an LH-RH-analog. They showed variable degree of li
ver hepatotoxicity and recovered after with drawal of flutamide. The l
iterature concerning tile metabolism of flutamide and the published ca
ses of hepatotoxicity of this drug are reviewed.
