RESUMO
PURPOSE: To evaluate survival, efficacy and safety of transarterial chemoembolization (TACE) in the treatment of patients with hepatocellular carcinoma (HCC), through a pooled analysis of patients with BCLC 0, A and B HCC stages, treated with polyethylene glycol drug eluting microspheres (PEG-DEM) TACE. MATERIALS AND METHODS: Patients from 3 retrospective and 2 prospective registries were included. Overall survival (OS), progression-free survival (PFS), tumour response and safety were evaluated. Multivariate Cox regression analysis was performed to evaluate predictors of OS. RESULTS: A total of 580 patients (72.1% males, mean age 66.9 ± 10.3 years) were included. 43.5% had BCLC A, and 41.0% BCLC B disease stage, and 85.8% were Child-Pugh class A. Complete and partial response (mRECIST or RECIST1.1) were achieved in 60.14% and 27.11% of patients, with overall response and disease control rates of 87.30% and 94.60%, respectively. Median OS was 50.8 months for the total population, and 61.2 and 38.1 months for BCLC 0 + A and BCLC B patients, respectively. Median PFS for the total population, BCLC 0 + A and BCLC B groups was 15.6, 21.6 and 12.7 months, respectively. CONCLUSIONS: This multicentric pooled analysis confirmed efficacy and safety of PEG-DEM TACE, with a median OS of 50.8 months.

BACKGROUND: Transarterial chemoembolization (TACE) is indicated for unresectable hepatocellular carcinoma. METHODS: This was a retrospective study of 50 hepatocellular carcinoma patients treated with TACE using doxorubicin-loaded LifePearl™ to investigate the safety and efficacy of TACE. RESULTS: There was no 30-day mortality, and limited adverse events were reported. At best tumor response, complete response and disease control were 58% and 94%, respectively, with a median of 4.5 months of follow-up. Median overall survival was 33.8 months. Patients with Barcelona Clinic Liver Cancer stage 0 and stage A at best tumor response showed a higher complete response rate (83%) than patients with Barcelona Clinic Liver Cancer stage B (complete response: 50%; p = 0.0414). CONCLUSION: Doxorubicin-loaded LifePearl™ TACE might be an effective treatment, with a good safety profile, for patients with early/intermediate-stage hepatocellular carcinoma. Further prospective data, especially with a small cohort of selected patients, are required to confirm these results.
