Liver Cancer Death Rate In Us Increases By 43% In 16 Years
Liver Cancer Death Rate In Us Increases By 43% In 16 Years.
Death rates from liver cancer increased 43% for American adults from 2000 to 2016, according to a report released Tuesday by the US Centers for Disease Control and Prevention’s National Center for Health Statistics. The increase comes even as mortality for all cancers combined has declined.
U.S. death rates from liver cancer have risen steadily since 2000, resulting in the disease going from the ninth-leading cause of cancer death to the sixth, a new report finds. But from 2000 to 2016, liver cancer death rates in adults ages 25 and up rose 43 percent, from 7.2 deaths per 100,000 people in 2000 to 10.3 deaths per 100,000 people in 2016, the report found. The rates increased for both men and women; however, the death rates for men were 2 to 2.5 times higher than the rates for women throughout the study period.

The rise in mortality doesn’t mean that liver cancer is deadlier than before, according to Dr. Jiaquan Xu, the author of the report; the 10-year survival rate for liver cancer didn’t change much. Rather, the increase in mortality means more people are developing liver cancer.
More than 70% of liver cancers are caused by underlying liver disease, which has risk factors such as obesity, smoking, excess alcohol consumption, and hepatitis B and C infection, said Dr. Farhad Islami, the scientific director of cancer surveillance research at the American Cancer Society.
“I think the main reason for the increase in liver cancer incidence and death rate in the US is the increase in the prevalence of excess body weight and hepatitis C virus infection in baby boomers,” said Islami, who authored a study on liver cancer occurrence between 1990 and 2014.
However, hasn’t seen similar improvements, Drebin said. For example, the rates of people getting liver cancer haven’t changed much, and the disease is still difficult to detect and, in many cases, treat. Drebin noted that although the rates of liver cancer due to some causes — such as hepatitis B, a viral infection that causes inflammation of the liver — have decreased, the rates of the disease due to other causes — including obesity-related cirrhosis, or scarring of the liver — have gone up. Therefore, the rates of people getting liver cancer due to different causes are “probably balanced out,” he said.
What’s more, even though new drugs are available to treat hepatitis C, another viral infection that causes liver inflammation, these drugs “may not prevent the eventual development of liver cancer,” Drebin said. According to Dr Drebin, Liver cancer death rates were the highest in adults ages 75 and up during the entire study period, the report found. Death rates rose for adults in this age group during the study period, as well as for adults ages 65 to 74 and adults ages 55 to 64. Adults ages 45 to 54 saw an increase in death rates from 2000 to 2005, followed by a decrease in rates from 2012 to 2016. Liver cancer death rates for adults ages 25 to 44 did not change during the study period.
The report also found that, after adjusting for age, liver cancer death rates in 2016 were the highest in Washington, D.C. (16.8 deaths per 100,000 people) and the lowest in Vermont (6 deaths per 100,000 people). The report is based on data from the National Vital Statistics System, a database that contains death certificates from all 50 states and the District of Columbia.
