A radioimmunoassay for transforming growth factor alpha (TGF-alpha) using synthetic rat sarcoma transforming growth factor and its rabbit polyclonal antibody has been developed. Using radioimmunoassays, the urinary TGF-alpha and epidermal growth factor (EGF) concentrations in 31 patients with hepatocellular carcinoma (HCC), 15 probable HCC, four metastatic liver cancer, and 33 age, sex-matched healthy controls were determined. For the first time, we have shown that the average TGF-alpha concentration for HCC patients was 21.5 +/- 20.3 micrograms per g creatinine, significantly higher than that of healthy subjects, 4.9 +/- 2.8 micrograms per g creatinine (P less than 0.001). There was no statistical difference in the level of EGF between HCC patients and controls (40.9 +/- 29.3 versus 46.2 +/- 16.6 micrograms per g creatinine; P greater than 0.05). The ratio of EGF/TGF-alpha between HCC patients (3.37 +/- 4.42) and controls (15.5 +/- 13.0) was significantly different (P less than 0.001). Among patients, 65% (20 of 31) of HCC cases and 87% (13 of 15) of probable HCC cases showed a marked elevation of TGF-alpha levels. We found only 16% (five of 31) of HCC cases with increased EGF level. EGF excretion was inversely age related. Serum total protein concentration and alkaline phosphatase activity were positively correlated to EGF concentration (r = 0.522, P less than 0.01 and rt = 0.393, P less than 0.05, respectively). There was no correlation between biochemical functions of liver and TGF-alpha concentration in HCC patients. Our results also suggested that TGF-alpha may be a useful complementary tumor marker for management of patients with clinical manifestation of HCC who have low alpha-fetoprotein levels.
