Evaluating the impact of treatment sequencing on outcomes in hepatocellular carcinoma: a comparative analysis of TACE and systemic therapies.

This study aimed to evaluate how the timing of transarterial chemoembolization (TACE) relative to systemic therapy (tyrosine-kinase inhibitors [TKIs] and immune checkpoint inhibitors [ICIs]) influences oncological outcomes in patients with hepatocellular carcinoma (HCC). A retrospective analysis was conducted on HCC patients treated with TACE plus TKIs and ICIs from January 2018 to February 2023. We compared objective response rate (ORR), disease control rate (DCR), overall survival (OS), and progression-free survival (PFS) between patients receiving TACE before versus after systemic therapies. Multivariate Cox regression analyses identified potential prognostic factors. Of the 194 patients enrolled, 111 received TACE before systemic therapies, and 83 after. The median age at diagnosis was 52.8 years. There were no significant differences in ORR (40.72% vs. 30.41%, p = 0.989) or DCR (48.45% vs. 35.57%, p = 0.770) between the groups. Likewise, OS (18.73 vs. 18.20 months, p = 0.091) and PFS (11.53 vs. 10.05 months, p = 0.336) were similar regardless of treatment sequence. In the result of Cox analysis, a 20% decrease in AFP from baseline at one month was associated with improved OS (HR = 0.35, 95% CI 0.17-0.70, p = 0.003) and PFS (HR = 0.69, 95% CI 0.49-0.96, p = 0.028). Large tumor size (≥ 10 cm) was a poor prognostic factor for OS (HR = 2.12, 95% CI 1.07-4.21, p = 0.032), and the presence of portal vein tumor thrombus adversely affected PFS (HR = 2.31, 95% CI 1.47-3.62, p < 0.001). The sequencing of TACE and systemic therapies does not significantly impact the prognosis of advanced HCC. A 20% reduction in AFP within one month of treatment commencement emerges as a protective prognostic factor for HCC.

Safety and efficacy of double plasma molecular adsorption system with sequential low-volume plasma exchange in intermediate-stage hepatitis B virus-related acute-on-chronic liver failure.

Current evidence suggests that the mortality rate of intermediate-stage hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) remains high. We aimed to investigate the safety and efficacy of double plasma molecular adsorption system (DPMAS) with sequential low-volume plasma exchange (LPE) treatment in intermediate-stage HBV-related ACLF. This prospective study recruited intermediate-stage HBV-related ACLF patients and was registered on ClinicalTrials.gov (NCT04597164). Eligible patients were randomly divided into a trial group and a control group. Patients in both groups received comprehensive medical treatment. Patients in the trial group further received DPMAS with sequential LPE. Data were recorded from baseline to Week 12. Fifty patients with intermediate-stage HBV-related ACLF were included in this study. The incidence of bleeding events and allergic reactions in the trial group was 12% and 4%, respectively, with no other treatment-related adverse events. The levels of total bilirubin and prothrombin time-international normalized ratio, and model for end-stage liver disease scores after each session of DPMAS with sequential LPE were significantly lower than those before treatment (all p < 0.05). The 12-week cumulative liver transplantation-free survival rates in the trial and control groups were 52% and 24%, respectively (p = 0.041). The 12-week cumulative overall survival rates in the trial and control groups were 64% and 36%, respectively (p = 0.048). The Kaplan-Meier survival analysis revealed significant differences in liver transplantation-free survival (p = 0.047) and overall survival (p = 0.038) between the trial and control groups. Cox regression analysis indicated that blood urea nitrogen (p = 0.038), DPMAS with sequential LPE (p = 0.048), and Chinese Group on the Study of Severe Hepatitis B-ACLF II score (p < 0.001) were significant risk factors for mortality. DPMAS with sequential LPE treatment is safe and effective for patients with intermediate-stage HBV-related ACLF.
