Hepatocellular carcinoma following direct anti-viral for hepatitis C treatment: a report of an Egyptian case series

引用

Hepatoma Research 2017年第8期3卷 178-181页

Egypt had been vexed by the highest load of chronic hepatitis C in the world. It represents a vast market of the new direct-acting anti-viral drugs (DAAs);effectively treating chronic hepatitis C virus (HCV) infection. Eradication of HCV in Egypt has been challenged by the observed increased diagnosis of hepatocellular carcinoma (HCC) in relation to DAAs therapy. This is the first Egyptian report annotating to a series of sixteen chronic HCV infected cases without a diagnosis of HCC before DAAs therapy and unexpected development of HCC during or after completion of DAAs therapy.
