[Epidemiology of hepatocellular carcinoma in the department of Calvados].
OBJECTIVE
The aim of this study was to determine the epidemiological characteristics of hepatocellular carcinoma in a non-selected population.


METHODS
Between 1984 and 1990, all cases of hepatocellular carcinoma were registered at the Registry of Digestive Tumors of Calvados. Standardized incidence rates were calculated for males and females. Prognostic factors were determined by the Cox multivariate method.


RESULTS
213 patients with hepatocellular carcinoma were registered. Standardized incidence rates were 7.5/100,000 in men and 0.4/100,000 in women. Sex-ratio was 18.3. Mean age was 66.4 years; hepatocellular carcinoma was uncommon (3%) before the age of 50. Cirrhosis was associated in 85.9% of patients. The cause of cirrhosis was known in 150 cases: alcoholic: 73.3%, cryptogenetic: 8.7%, viral B or C: 7.3%, alcoholic and viral B or C: 5.3%, and genetic hemochromatosis: 4.7%. The overall survival rate in 203 patients was 21%, 8% and 3% at 1 year, 3 years and 5 years, respectively. The multivariate study identified 4 prognostic factors: number of tumors < or = 2, lack of ascites, serum alpha-fetoprotein < or = 10 mg/mL, and hepatocellular carcinoma revealing a well-compensated liver disease until the time of diagnosis.


CONCLUSIONS
The occurrence of hepatocellular carcinoma seems to be linked to cirrhosis, male sex, and age > 50, which could be used as the main selection criterias for the screening of hepatocellular carcinoma.
