BACKGROUND Liver transplantation(LT)is a potentially curative therapy for patients with hepatocellular carcinoma(HCC).HCC-recurrence following LT is associated with reduced survival.There is increasing interest in chemoprophylaxis to improve HCC-related outcomes post-LT.AIM To investigate whether there is any benefit for the use of drugs with proposed chemoprophylactic properties against HCC,and patient outcomes following LT.METHODS This was a retrospective study of adult patients who received Deceased Donor LT for HCC from 2005-2022,from a single Australian centre.Drug use was defined as statin,aspirin or metformin therapy for≥29 days,within 24 months post-LT.A cox proportional-hazards model with time-dependent covariates was used for survival analysis.Outcome measures were the composite-endpoint of HCC-recurrence and all-cause mortality,HCC-recurrence and HCC-related mortality.Sensitivity analysis was performed to account for immortality time bias and statin dosing.RESULTS Three hundred and five patients were included in this study,with 253(82.95%)males with a median age of 58.90 years.Aetiologies of liver disease were 150(49.18%)hepatitis C,73(23.93%)hepatitis B(HBV)and 33(10.82%)non-alcoholic fatty liver disease(NAFLD).56(18.36%)took statins,51(16.72%)aspirin and 50(16.39%)metformin.During a median follow-up time of 59.90 months,34(11.15%)developed HCC-recurrence,48(15.74%)died,17(5.57%)from HCC-related mortality.Statin,aspirin or metformin use was not associated with statistically significant differences in the composite endpoint of HCC-recurrence or all-cause mortality[hazard ratio(HR):1.16,95%CI:0.58-2.30;HR:1.21,95%CI:0.28-5.27;HR:0.61,95%CI:0.27-1.36],HCC-recurrence(HR:0.52,95%CI:0.20-1.35;HR:0.51,95%CI:0.14-1.93;HR 1.00,95%CI:0.37-2.72),or HCC-related mortality(HR:0.32,95%CI:0.033-3.09;HR:0.71,95%CI:0.14-3.73;HR:1.57,95%CI:0.61-4.04)respectively.Statin dosing was not associated with statist-ically significant differences in HCC-related outcomes.CONCLUSION Statin,metformin or aspirin use was not associated with improved HCC-related outcomes post-LT,in a largely historical cohort of Australian patients with a low proportion of NAFLD.Further prospective,multicentre studies are required to clarify any potential benefit of these drugs to improve HCC-related outcomes.
