Etiologic factors and clinical presentation of hepatocellular carcinoma : differences between cirhotic and noncirrhotic Italian patients.
It is not known whether the prevalence of hepatocarcinogenic factors differs between cirrhotic and noncirrhotic patients with hepatocellular carcinoma (HCC) or whether the clinical presentation of HCC in these two groups differs.
The prevalence of the putative etiologic factors of HCC and its clinical presentation in 373 patients with cirrhosis and 102 without cirrhosis seen from 1981 to 1992 were evaluated.
Hepatitis C virus infection (76 vs. 48%, P=0.003) and both current (22.5 vs. 10%, P=0.007) and past (50.5 vs. 34.5%, P=0.045) hepatitis B virus infections were more common in cirrhotic than in noncirrhotic patients with HCC.
The absence of exposure to both viruses was much less frequent in the former (7 vs. 40%, P<0.001).
Heavy alcohol intake prevailed in patients with cirrhosis (30 vs. 16.5%, P=0.01).
Abdominal pain was the most common presenting symptom in both groups.
Signs of hepatic decompensation prevailed in cirrhotic patients, whereas a « toxic syndrome » dominated the clinical picture of the noncirrhotic patients.
Hepatitis viruses are associated more with carcinogenesis of the cirrhotic than of the noncirrhotic liver.
Alpha-fetoprotein is not a sensitive neoplastic marker, particularly in noncirrhotic patients.
In the latter, HCC appears more advanced at diagnosis and symptoms of neoplastic toxicity are prominent.
