(SACRAMENTO, Calif.) Among Asian-Americans living in California, Laotian/Hmong-Americans have the lowest survival rates for the most common type of liver cancer, a new study by researchers with the UC Davis School of Medicine has found.
The study, the largest population-based examination of liver cancer rates among Asian-Americans, highlights a profound disparity that calls for targeted outreach to detect and treat the disease earlier among Laotian/Hmong-Americans, said Moon Chen Jr., a professor of hematology and oncology in the UC Davis School of Medicine.
"We knew that liver cancer is the most significant and prominent cancer health disparity affecting Asian-Americans. But we wanted to look at which Asian-American population was most at risk of dying from the disease," said Chen, who also is associate director of cancer control at UC Davis Cancer Center.
"If we do an intervention, not only do we have to address the characteristics of a particular disease. We have to figure out how to reach the specific population that is affected."
The study, "Disparities in Hepatocellular Carcinoma Survival among Californians of Asian Ancestry, 1988-2007," is published online in the journal Cancer Epidemiology, Biomarkers & Prevention. The research was conducted by UC Davis along with colleagues at the California Department of Public Health and UC San Francisco.
The study used California Cancer Registry data from more than 6,000 Asian-American patients diagnosed with hepatocellular carcinoma (HCC) between 1988 and 2007. It found stark differences in survival rates among the nine largest Asian-American groups in California, including Chinese, Filipino, Vietnamese, South Asian, Korean, Japanese, Laotian/Hmong, Cambodian and Thai.
Although much more prevalent in other parts of the world, liver cancer incidence in the United States is on the rise, and death rates from the disease have increased faster for both
