Core Tip
Core tip: This study examined survival and recurrence in hepatocellular carcinoma patients who did or did not undergo transarterial chemoembolization (TACE). Analyses were performed with all patients and with propensity score-matched pairs. Both analyses suggest adjuvant TACE does not reduce recurrence. Furthermore, adjuvant TACE does not improve overall survival among propensity score-matched patients. These findings raise important questions about the efficacy of postoperative adjuvant TACE that future work should address in order to justify the use of this technique as well as identify the patient populations most likely to benefit from it.
