Transarterial chemoembolisation for very early and early stage hepatocellular carcinoma: single-centre experience.

To evaluate the safety and efficacy of transarterial chemoembolisation (TACE) in patients with very early and early stage hepatocellular carcinoma (VES-HCC). A retrospective analysis was performed for all TACE procedures done at King's College Hospital, a tertiary liver centre, for VES-HCC during a 5-year period (January 2014-December 2018). Patients with solitary tumours ≤5 cm and patients with 2-3 tumours (each ≤3 cm) were included. Two hundred and thirty-seven eligible patients were included. Technical success was achieved in 233 (98.3%) procedures. TACE using drug-eluting beads (DEB-TACE) was performed in 192 (82.4%) procedures. A complete response was achieved in 109 (45.9%) patients. The recurrence rate was 44% (48 cases), during a median imaging follow-up of 31.9 months (IQR 15.9-44.7). Median overall survival was 71.1 months (95% confidence interval [CI]: 62.9-79.3). Median recurrence-free survival was 58.9 months (95% CI: 47.1-70.7). Sixty-six (27.8%) patients eventually underwent transplantation, and six (2.5%) patients underwent surgical resection. Mild, moderate, and severe adverse events were encountered in 2.9%, 5.4%, and 0.8% of cases, respectively. No 30-day mortality was encountered. DEB-TACE is safe and effective for treating VES-HCC patients, who are unsuitable for thermal ablation or surgery, and may offer comparable survival benefit. It can also be used as a bridge to transplantation for these patients.
