Abstract
ABSTRACT Objective To explore the clinical efficacy and prognostic factors of the use of Gelfoam for drug-eluting bead (DEB) transarterial chemoembolization (GMD-TACE) in patients with unresectable large hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT). Methods A retrospective analysis was conducted using the mRECIST standard to evaluate tumor response after GMD-TACE. Overall survival time, median survival time, time to progression (TTP) after the first intervention, and other treatment methods were recorded. Results The follow-up time was 2–110 months (mean 17.97 + 19.12 months), the median follow-up time was 12.5 months, and the first TTP after the first GMD-TACE was 4 months (95% CI 3.020–4.980). The median overall survival (OS) time was 14 months (95% CI 9.801–18.199). The 1-, 3-, and 5-year survival rates were 53.6%, 32.3%, and 8.9%, respectively. Multivariate analysis showed that the type of tumor thrombus was an independent factors affecting prognosis, and combination therapy was a protective factor affecting prognosis. Conclusions GMD-TACE can be used as the core treatment for unresectable large HCC combined with a PVTT. This can improve the quality of life and further improve the median OS, and is worthy of clinical promotion and application.
