| 概要 | AIM:Evidence regarding the optimal first-line immune checkpoint inhibitor (ICI) regimen for treating unresectable hepatocellular carcinoma (uHCC) with Child-Pugh class B (CP-B) liver function remains limited. This study compared atezolizumab plus bevacizumab (Atez/Bev) and durvalumab plus tremelimumab (Dur/Tre group) in real-world settings.METHODS:In this multicenter retrospective study, 211 consecutive patients with uHCC and CP-B liver function who underwent ICI-based therapy as a first-line therapy were analyzed. Treatment responses, survival outcomes, albumin-bilirubin (ALBI) score changes, and adverse events were evaluated. Survival analyses were adjusted using inverse probability weighting (IPW).RESULTS:The median progression-free survival associated with the Atez/Bev and Dur/Tre regimens was 5.0 and 3.5 months, respectively; the median corresponding overall survival was 10.5 and 12.4 months. After IPW adjustment, no significant differences were observed in progression-free or overall survival. The Atez/Bev regimen-associated disease control rate was significantly higher (75.2% vs. 55.0%, p = 0.02). The Dur/Tre regimen, meanwhile, was associated with a significantly higher immune-related adverse event incidence (10.5% vs. 32.7%, p < 0.01) and a greater need for high-dose corticosteroid treatment. In contrast, the Atez/Bev regimen resulted in a progressive decrease in ALBI scores, whereas the Dur/Tre regimen maintained the hepatic functional reserve.CONCLUSIONS:The Atez/Bev and Dur/Tre regimens afforded comparable survival outcomes but differed substantially in safety and effects on the hepatic functional reserve. Given the trade-off between immunotoxicity and liver function preservation, treatment selection for CP-B liver function should be individualized, considering baseline hepatic reserve, tolerability, and anticipated treatment trajectory. |
