Serum levels of estrogens and testosterone in cirrhotic men with and without hepatocellular carcinoma.
Serum levels of estrogens and testosterone were measured in 25 male patients with hepatocellular carcinoma and associated cirrhosis of the liver and in another 25 male patients with cirrhosis only. The two groups were statistically comparable in terms of age distribution, duration of liver disease, incidence of alcohol abuse, incidence of hepatitis B surface antigenemia, and grade of hepatic dysfunction. Estrone was significantly elevated in both groups of patients. Estradiol concentrations were above normal in 10 patients with hepatocellular carcinoma and in 11 with cirrhosis only. All patients had normal concentrations of estriol. There were no statistical differences between the two groups in either individual or total estrogen levels (estrone 0.05 less than p less than 0.1). Eight of the patients with hepatocellular carcinoma and 5 of the cirrhotics had lower testosterone levels than normal, but this difference was not significant. However, the estrone to testosterone ratios were significantly higher in the hepatocellular carcinoma group than in the cirrhosis group (p less than 0.05). The present study seems to indicate that hyperestrogenemia commonly seen in male patients with liver cirrhosis may play some role in hepatic carcinogenesis of cirrhotic livers. Further studies are needed to determine if the estrone to testosterone ratio is implicated in hepatocarcinogenesis in cirrhotic men.
