Abstract
Purpose: In the treatment of hepatocellular carcinoma (HCC) with transarterial radioembolization (TARE), identifying reliable biomarkers for predicting survival outcomes remains a critical challenge. We aimed to address this gap by investigating the significance of serum cytokines associated with inflammation as potential biomarkers for the selection of patients for TARE.
Methods: Our retrospective study involved 161 patients diagnosed with HCC who underwent Y90 radioembolization at our medical center between 2010 and 2020. Serum samples from a subset of 78 patients were retrospectively analyzed to determine the concentrations of pro-inflammatory cytokines. The results from the prospective SORAMIC trial were used for independent validation.
Results: With a median overall survival of 36 weeks (range 4-436), our study showed the strongest correlation between 12-week survival and IL-8 levels before treatment (p < 0.001), while other relevant interleukins, interferon-α2, INF-γ, TNF-α and MCP-1 were not associated with survival. IL-8 levels below the cut-off of 190 pg/mL were significantly associated with increased 12-week and 24-week survival, with hazard ratios of 19.01 (95% CI: 2.29-157.89) and 2.57 (95% CI: 1.05-6.31), respectively (p = 0.006 and p = 0.039, respectively). In the adjusted multivariate analysis, the 190 pg/mL cut-off for IL-8 remained independently associated with 12- (p = 0.011) and 24-week survival (p = 0.039). Similarly, the SORAMIC population showed a strong association between IL-8 levels and 36-week survival (p = 0.03).
Conclusion: Our study emphasizes the pivotal role of IL-8 as a valuable parameter, demonstrating its potential for predicting treatment outcomes and assessing liver function in patients with HCC undergoing TARE. The robustness of these findings warrants further validation.
