摘要

Background and aims

AST-lymphocyte ratio index (ALRI) has been proposed as a potentially prognostic indicator of liver cancer patients underwent transcatheter arterial chemoembolization (TACE) in studies, but the numbers were small and the results were controversial. In this study, we systematically assessed the prognostic value of ALRI in liver cancer patients treated with TACE by integrating meta-analysis with single-center clinical analysis.

Methods

We conducted a systematic literature search across multiple databases and evaluated the quality of included studies using the Newcastle-Ottawa Scale. We employed a fixed-effect model to calculate the pooled hazard ratio (HR) and 95% confidence interval (CI). Publication bias were evaluated using funnel plot, Begg’s and Egger’s tests. Concurrently, we integrated clinical data from 127 HCC patients treated with TACE at our center, employed X-tile software to ascertain the optimal cutoff value for ALRI, and analyzed the relationship between ALRI and clinical characteristics as well as overall survival (OS), using chi-square tests, Kaplan-Meier survival curves, and Cox proportional hazards models.

Results

The meta-analysis included 7 studies, and the pooled hazard ratio (HR) indicated that elevated ALRI was significantly associated with poorer OS in liver cancer patients underwent TACE (HR = 1.75, 95% CI: 1.46–2.1, P<0.01), with no significant heterogeneity (P = 0.542, I2 = 0.00%). Clinical analysis of 127 patients further supported this finding, with patients in the high ALRI group showed significantly lower OS compared to those in the low ALRI group (1-year OS rate: 96.7% vs. 87.9%, 2-year OS rate: 61.5% vs. 42.7%; C2 = 28.006, P<0.01). Multivariate Cox regression analysis revealed that number of tumors, tumor size and ALRI were all independent prognostic factors for OS (ALRI HR = 6.456, 95%CI: 2.247–18.55, P < 0.01).

Conclusions

An increase in ALRI may serve as an independent prognostic indicator of poor outcomes in liver cancer patients undergoing TACE. While it offers benefits such as being non-invasive and cost-effective, further large-scale, multicenter, prospective studies are essential to validate the efficacy of ALRI and establish standardized cutoff values for clinical application.
