Background: Transarterial chemoembolization (TACE) is widely used for patients with unresectable hepatocellular carcinoma (HCC); however, previous studies have demonstrated that conventional TACE (cTACE) might affect hepatic hemodynamics, which both associate with liver cirrhosis and survival. Drugeluting bead TACE (DEB-TACE) improves treatment efficacy and safety, but its effects on the hepatic hemodynamics of HCC patients with cirrhosis remain unknown.Methods: This retrospective cohort study included unresectable HCC patients treated with DEB-TACE from April 2018 to September 2020, who had limited tumor burden and liver function. The hepatic hemodynamics was measured by hepatic venous pressure gradient (HVPG) using occlusion balloon catheter before and after treatment. Baseline characteristics of demography, laboratory (tumoral and liver-function) and hepatic hemodynamics were compared between patients with and without clinically significant portal hypertension (CSPH). Laboratory examination and imaging assessments were performed 4-6 weeks; overall survival (OS) was defined as the time from DEB-TACE initiation until death or last follow-up.Results: Twenty-four eligible consecutive HCC patients were included, with a median age of 58.0 years and 54.2% in Child-Pugh A class. During a median follow-up of 9.8 months, median OS for the whole cohort of patients reached 10.0 months. Kaplan-Meier survival curves and Cox regression analyses demonstrated that age >60 years, ascites, Eastern Cooperative Oncology Group (ECOG) score of 1, Child-Pugh B class, Model for End-Stage Liver Disease (MELD) score >10, and albumin (ALB) <35 g/L were prognostic factors for decreased OS (P<0.05). Importantly, hepatic hemodynamics were significantly improved in patients after treatment with DEB-TACE (7.5 vs. 5.3 mmHg of HVPG, P<0.001), especially for those with CSPH (13.6 vs. 10.2 mmHg of HVPG, P=0.014).Conclusions: DEB-TACE can improve hepatic hemodynamics in HCC patients, especially those with CSPH. Combing these findings with its effects on tumor, DEB-TACE might be more suitable for HCC patients with cirrhosis.
