The Advanced Lung Cancer Inflammation Index as a Prognostic Indicator in Patients With Unresectable Hepatocellular...

We aimed to determine the associations between the pretreatment Advanced Lung Cancer Inflammation Index (ALI) and survival outcomes in patients with unresectable hepatocellular carcinoma (u-HCC) who received atezolizumab plus bevacizumab (Atez/Bev).

This retrospective study analyzed 563 patients with u-HCC who were treated with Atez/Bev (Sept 2020-Dec 2024). The ALI was calculated according to Body Mass Index × serum albumin level/neutrophil-to-lymphocyte ratio. Associations between ALI and overall survival (OS) and progression-free survival (PFS) were evaluated by Cox proportional hazards regression analysis.

An ALI cutoff value of 27.04, determined by receiver operating characteristic curve analysis, was used to classify patients into low- and high-ALI groups. High-ALI patients had longer median OS (26.1 vs. 13.7 months, p < 0.001) and PFS (9.3 vs. 5.2 months, p < 0.001), and a higher disease control rate (82.5% vs. 69.1%, p < 0.001) compared to low-ALI patients. Multivariate Cox regression analysis confirmed that a high ALI value was a significant prognostic marker for OS (hazard ratio [HR] 0.69, 95% confidence interval [CI] 0.54-0.88, p = 0.003) and PFS (HR: 0.75, 95% CI: 0.61-0.92, p = 0.006). Subgroup analyses showed that the trend toward improved outcomes was consistent for high ALI values in all clinically relevant subgroups.

A high pretreatment ALI value was associated with improved survival and disease control in u-HCC patients receiving Atez/Bev, underscoring its potential utility as a prognostic marker for clinical management and further studies.
