Comparison of survival between adolescent and young adult older patients with hepatocellular carcinoma.

Background: Due to the special clinical features and biologic characteristics of adolescent and young adult (AYA) cancers, AYA cancers are different from cancers in children and elderly individuals. However, there are few reports on AYA hepatocellular carcinoma (HCC).

Aim: To investigate the overall survival (OS) of AYA (15-39 years) and elderly (40-74 years) patients with HCC.
