Synthetic “Forever Chemical” Linked to Liver Cancer

Exposure to a synthetic chemical found widely in the environment is linked to non-viral hepatocellular carcinoma, the most common type of liver cancer, according to a new study conducted by researchers from the Keck School of Medicine of USC and published in JHEP Reports.

Exposure to a synthetic chemical found widely in the environment is linked to non-viral hepatocellular carcinoma, the most common type of liver cancer, according to a new study conducted by researchers from the Keck School of Medicine of USC and published in JHEP Reports.

The chemical, called perfluooctane sulfate or PFOS, is one of a class of man-made chemicals called per- and polyfluoroalkyl substances, or PFAS. These chemicals, which are used in a wide range of consumer and industrial products, are sometimes called forever chemicals because they break down very slowly and accumulate in the environment and human tissue, including the liver.

Prior research in animals has suggested that PFAS exposure increases the risk of liver cancer, but this is the first study to confirm an association using human samples.

“This builds on the existing research, but takes it one step further,” said Jesse Goodrich, PhD, a postdoctoral scholar in the Department of Population and Public Health Sciences at the Keck School of Medicine. “Liver cancer is one of the most serious endpoints in liver disease and this is the first study in humans to show that PFAS are associated with this disease.”
