Aspirin use and risk of hepatocellular carcinoma incidence and mortality in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial

Incidence of and mortality from hepatocellular carcinoma (HCC) in the United States has been increasing over the last several decades (1, 2). Due to these increasing trends, uncovering mechanisms for cancer prevention is a significant public health need. The long-term use of aspirin has demonstrated efficacy in reducing overall gastrointestinal cancer risk (3, 4). Recent clinical data has linked aspirin use to reduced risk of incident HCC (5). However, the potential benefits of aspirin for HCC prevention may be influenced by the presence of comorbidities, including underlying viral hepatitis, obesity and type 2 diabetes (6). For example, among individuals with hepatitis B infection, risk of HCC showed a dose-response relationship with another cancer preventive agent, statins (7). A similar association was noted among individuals with type 2 diabetes (8). Due to the widespread use and cancer preventive potential of aspirin, further evaluating the association between aspirin use, comorbidities, and HCC risk is warranted. Therefore, in this study, we propose to examine the association of aspirin use with risk of incident HCC and HCC-related mortality in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial. We will further evaluate HCC risk among individuals with and without underlying comorbidities, such as viral hepatitis, obesity and diabetes.
