Purpose: The incidence of flutamide-related liver toxicity was studied in 56 korean
patients, treated for advanced prostate cancer with flutamide combined with a LHRH
agonist or orchiectomy.
Materials and Methods: Serum glutamic oxaloacetic transaminase(SGOT), serum
glutamic pyruvic transaminase(SGPT), total bilirubin and alkaline phosphatase were
measured to assess liver function at baseline, 1, 2 and 3 months and every 3 months
thereafter. When they were elevated three-fold or more than upper normal levels, we
regarded it as a presence of liver toxicity. Viral marker studies (Hepatitis B, C) were
performed in patients with elevated SGOT and/or SGPT after flutamide administration.
Results: Ten patients(17.9%) showed elevated SGOT and/or SGPT at an average of 3
months after flutamide administration. All patients who performed viral marker studies
revealed negative results. Total serum bilirubin was elevated in three(5.4%) patients and
clinical jaundice appeared in one(1.8%). All clinical and biochemical manifestations of
liver toxicity disappeared within two months after discontinuation of flutamide and no
sequelae was observed for 15 months.
Conclusions: The Incidence of flutamide-Induced hepatotoxicity seems to be higher In
Korea than in North America. But this might not be due to the fact that Korea is an
endemic area of viral hepatitis. Further study will be necessary for the verification of
dose-related toxicity of flutamide in Korean prostate cancer patients. We recommend
liver function test periodically to patients treated with flutamide.
