A proper trial would settle whether statins should be prescribed for prevention.","summary":"Large observational studies and meta-analyses associate statin use with substantially lower hepatocellular carcinoma incidence in cirrhosis and chronic hepatitis, with plausible mechanisms (reduced portal pressure, anti-fibrotic and anti-proliferative effects), and small randomised trials of simvastatin in cirrhosis show improved portal haemodynamics. No adequately powered prevention trial with cancer incidence as the endpoint has been completed. The proposal is a pragmatic randomised trial of atorvastatin or simvastatin versus placebo in compensated cirrhosis with HCC incidence as the primary outcome, run through hepatology networks and registries.","asOf":"2026-09-08","links":[{"label":"Bottleneck evidence (No incentive to repurpose cheap drugs): Pantziarka et al., The Repurposing Drugs in Oncology (ReDO) Project (ecancer 2014)","url":"https://doi.org/10.3332/ecancer.2014.442"}],"tags":[],"related":[],"cancers":["hcc"],"sections":[],"technologies":[],"targets":[],"drugs":[],"companies":[],"institutions":[],"pathways":[],"terms":[],"trials":[],"people":[],"bottlenecks":["b-generic-repurposing","b-prevention-adoption"],"keyPapers":["paper-pantziarka-ecancermedicalscience"],"journals":[],"dependsOn":[],"notes":[],"hypothesis":"Statin therapy reduces the 5-year incidence of hepatocellular carcinoma in compensated cirrhosis by at least 30% relative to placebo.","rationale":"Cirrhosis is one of the few settings where a very high-risk population is already under surveillance, making a prevention trial feasible with a few thousand patients; the drug is safe, cheap and already indicated in many of these patients for cardiovascular reasons.","test":"Randomised placebo-controlled trial of about 3,000 patients with compensated cirrhosis followed for five years with ultrasound surveillance; HCC incidence primary endpoint.","maturity":"early-clinical","actor":"research","cost":"medium","horizonYears":7},"route":"/ideas/idea-reg-statin-hcc-prevention-trial/","neighbours":{"cancer":[{"id":"hcc","kind":"cancer","name":"Hepatocellular carcinoma","route":"/cancers/hcc/"}],"bottleneck":[{"id":"b-generic-repurposing","kind":"bottleneck","name":"No incentive to repurpose cheap drugs","route":"/bottlenecks/b-generic-repurposing/"},{"id":"b-prevention-adoption","kind":"bottleneck","name":"Prevention we already have is not deployed","route":"/bottlenecks/b-prevention-adoption/"}],"paper":[{"id":"paper-pantziarka-ecancermedicalscience","kind":"paper","name":"The Repurposing Drugs in Oncology (ReDO) Project","route":"/key-papers/paper-pantziarka-ecancermedicalscience/"}]}}
