Hepatocellular Carcinoma Rates Vary Widely Across Sex and Racial/Ethnic Groups

By Liz Highleyman

Chronic hepatitis B or C, heavy alcohol use, and other conditions that damage the liver can progress over years or decades to severe fibrosis, cirrhosis, or hepatocellular carcinoma (HCC), a form of primary liver cancer.



The overall incidence of HCC in the U.S. has risen in recent years, presenting a serious public health challenge. But the distribution of liver cancer in the population, and variations in risk according to demographic group, have not been well characterized.

As described in the June 2008 American Journal of Medicine, Robert Wong from the University of California at San Francisco and Douglas Corley from Kaiser Permanente Northern California conducted a retrospective study to evaluate sex-specific, race/ethnicity-specific, and age-specific variations in HCC incidence from 1992 through 2004.

They used data from the Surveillance, Epidemiology, and End Results (SEER) program, administered by the National Cancer Institute, which collects incidence and survival data from population-based cancer registries throughout the U.S.

Results

With men and women combined, HCC incidence was highest among Asians, nearly double the rate of white Hispanics (11.0 vs 6.8 per 100,000 person-years).

The combined Asian rate was more than 4 times higher than the rate for Caucasians (11.0 vs 2.6 per 100,000 person-years).

Among males, liver cancer rates doubled every 10 years from age 30 to 50 years.

Females reached cancer rates comparable to those of males about 10-15 years later.

For all racial/ethnic groups, HCC rates among females peaked at significantly lower values compared with men.

"Marked differences in the incidence rates of hepatocellular carcinoma by sex, ethnicity, and age of diagnosis likely represent variations in risk factor distributions (e.g., viral hepatitis) and possibly in host genetics or other environmental factors," the study authors concluded.

They added that, "An individualized approach tailored to specific risk profiles may more effectively identify treatable tumors than more general guidelines."

What is Hepatocellular Carcinoma? Most primary liver cancers are classified as hepatocellular carcinoma. Hepatocellular carcinoma is a malignant tumor composed of cells resembling hepatocytes ; however, the resemblance varies with the degree of differentiation . Hepatocellular carcinoma is commonly associated with cirrhosis
