TACE Combined With Tislelizumab, Lenvatinib, and Carvedilol for Unresectable HCC With Cirrhotic Portal Hypertension

Summary

In China, the majority of hepatocellular carcinoma (HCC) cases stem from chronic hepatitis B virus (HBV) infection and subsequent cirrhosis, with patients often presenting at the decompensated stage complicated by clinically significant portal hypertension (CSPH). CSPH not only limits treatment options and worsens prognosis but also leads to the frequent exclusion of such patients from pivotal clinical trials, resulting in a lack of high-level evidence for their management. Carvedilol, a non-selective beta-blocker, is a first-line therapy for portal hypertension. Emerging evidence suggests that this drug class may also modulate the tumor microenvironment and enhance the efficacy of immune checkpoint inhibitors. To address this unmet need, this study aims to explore a novel quadruple-therapy strategy (TACE + tislelizumab + lenvatinib + carvedilol) for the treatment of unresectable HCC with concurrent cirrhotic portal hypertension. The rationale is twofold: while controlling portal hypertension and safeguarding treatment safety, carvedilol may also potentiate immunotherapy by modulating adrenergic signaling, thereby achieving dual benefits of "liver protection" and "anti-cancer" synergy. Utilizing an efficient Simon's two-stage design, this study will conduct a preliminary assessment of the regimen's efficacy and safety with minimal risk, providing essential data to inform future confirmatory research.
