RESUMO

BACKGROUND AND AIMS: Deterioration of liver function is a leading cause of death in patients with advanced hepatocellular carcinoma (HCC). We evaluated the impact of immune checkpoint inhibitor (ICI)-treatment on liver function and outcomes. METHOD: HCC patients receiving ICIs or sorafenib between 04/2003 and 05/2024 were included. Liver function (assessed by Child-Pugh score [CPS]) was evaluated at the start of ICI-treatment (baseline, BL) and 3 and 6 months thereafter. A ≥1 point change in CPS was defined as deterioration (-) or improvement (+), while equal CPS points were defined as stable (=). RESULTS: Overall, 182 ICI-treated patients (66.8 ± 11.8 years; cirrhosis: n = 134, 74%) were included. At BL, median CPS was 5 (IQR: 5-6; CPS-A: 147, 81%). After 3 months, liver function improved/stabilized in 102 (56%) and deteriorated in 61 (34%) patients, while 19 (10%) patients deceased/had missing follow-up (d/noFU). Comparable results were observed at 6 months (+/=: n = 82, 45%; -: n = 55, 30%; d/noFU: n = 45, 25%). In contrast, 54 (34%) and 33 (21%) out of 160 sorafenib patients achieved improvement/stabilization at 3 and 6 months, respectively. Radiological response was linked to CPS improvement/stabilization at 6 months (responders vs. non-responders, 73% vs. 50%; p = 0.007). CPS improvement/stabilization at 6 months was associated with better overall survival following landmark analysis (6 months: +/=: 28.4 [95% CI: 18.7-38.1] versus -: 14.2 [95% CI: 10.3-18.2] months; p < 0.001). Of 35 ICI-patients with CPS-B at BL, improvement/stabilization occurred in 16 (46%) patients, while 19 (54%) patients deteriorated/d/noFU at 3 months. Comparable results were observed at 6 months (CPS +/=: 14, 40%, -: 8, 23%). Importantly, 6/35 (17%) and 9/35 (26%) patients improved from CPS-B to CPS-A at 3 and 6 months. CONCLUSION: Radiological response to ICI-treatment was associated with stabilization or improvement in liver function, which correlated with improved survival, even in patients with Child-Pugh class B at baseline.

RESUMO

BACKGROUND & AIMS: The value of bleeding prophylaxis and anticoagulation in patients with hepatocellular carcinoma (HCC) and macrovascular tumour invasion (MVI) is unclear. We evaluated the impact of anticoagulation on thrombosis progression, bleeding events, and overall mortality, and assessed the efficacy of adequate management of varices as recommended for patients with cirrhosis. METHODS: HCC patients with MVI who had Child-Turcotte-Pugh A-B7 were included between Q4/2002 and Q2/2022. Localization of the tumour thrombus and changes at 3-6 months were evaluated by two radiologists. Univariable and multivariable logistic/Cox regression analyses included time-dependent variables (i.e., anticoagulation, systemic therapy, non-selective beta blocker treatment). RESULTS: Of 124 patients included (male: n = 110, 89%), MVI involved the main portal vein in 47 patients (38%), and 49 individuals (40%) had additional non-tumorous thrombus apposition. Fifty of 80 patients (63%) with available endoscopy had varices. Twenty-four individuals (19%) received therapeutic anticoagulation and 94 patients (76%) were treated with effective systemic therapies. The use of therapeutic anticoagulation did not significantly affect the course of the malignant thrombosis at 3-6 months. Systemic therapy (aHR: 0.26 [95%CI: 0.16-0.40]) but not anticoagulation was independently associated with reduced all-cause mortality. In patients with known variceal status, adequate management of varices was independently associated with reduced risk of variceal bleeding (aHR: 0.12 [95%CI: 0.02-0.71]). In the whole cohort, non-selective beta blockers were independently associated with reduced risk of variceal bleeding or death from any cause (aHR: 0.69 [95%CI: 0.50-0.96]). CONCLUSION: Adequate bleeding prophylaxis and systemic anti-tumour therapy but not anticoagulation were associated with improved outcomes in patients with HCC and MVI.
