Declining US Hepatocellular Carcinoma Rates, 2014-2017.

Area of Science:

• Hepatology
• Cancer Epidemiology
• Public Health

Background:

• Liver cancer, particularly hepatocellular carcinoma (HCC), is a major cause of cancer mortality in the US.
• Historically, HCC incidence rates in the US have risen significantly over several decades.
• Recent data suggested a possible flattening or decrease in HCC rates.

Purpose of the Study:

• To determine if the previously observed 4% decrease in US HCC rates in 2016 represented a true downward trend.
• To analyze the trajectory of HCC rates through 2017.

Main Methods:

• Analysis of national cancer incidence data.
• Examination of trends in hepatocellular carcinoma (HCC) rates.

Main Results:

• The study provides updated data on HCC rates through 2017.
• Confirms or refutes the downward trend observed in 2016.

Conclusions:

• The findings will clarify the recent trends in HCC incidence.
• Implications for public health strategies and cancer prevention efforts.
