The use of transarterial chemoembolization (TACE) has been extensively employed for managing unresectable hepatocellular carcinoma (HCC). However, there is limited evidence regarding the safety and effectiveness of TACE specifically in individuals aged 80 years and above.Aim: To examine the safety and effectiveness of TACE in elderly patients (≥ 80 years) compared to younger patients (< 80 years) with HCC, and the potential risk factors that may impact the progression-free survival (PFS) for TACE were also identified.Methods: A retrospective analysis was conducted on a consecutive cohort of unresectable HCC patients who were initially treated with TACE. The patients were categorized into two groups based on the age at which they underwent TACE, and the efficacy and safety of the treatment were evaluated. The PFS was investigated, and the prognostic factors were analyzed using the Kaplan-Meier method and Cox proportional hazard models.Results: A total of 198 patients were included in this study, with 44 patients aged 80 years or older and 154 patients younger than 80 years. The cumulative risk of PFS after TACE was similar between the two groups (P = 0.800). In the multivariate analysis, a lower ECOG score (P = 0.039) and an earlier BCLC stage (P = 0.004) were identified as independent predictors of better PFS. Patients in both groups tolerated the TACE treatment well.Conclusion: The impact of aging on poor PFS is not significant. In patients with HCC, TACE therapy is both safe and effective for octogenarians, similar to younger patients. Furthermore, the better PFS is associated with a low ECOG score and an early BCLC stage.Keywords: transarterial chemoembolization, hepatocellular carcinoma, elderly patients, octogenarians
