Neutrophil-Lymphocyte Ratio Predicts Overall Survival in Patients With HCC Treated With Durvalumab Plus Tremelimumab

To investigate the prognostic impact of the neutrophil-to-lymphocyte ratio (NLR) on outcomes in patients with hepatocellular carcinoma (HCC) treated with durvalumab plus tremelimumab (Dur/Tre).

A total of 182 patients with HCC who received Dur/Tre were included in the analysis. Univariate and multivariate survival analyses were conducted. Additionally, hazard ratio (HR) spline curve analysis was used to determine the optimal NLR cut-off values for predicting overall survival (OS).

The median progression-free survival (PFS) was 3.5 months (95% confidence interval [CI]: 2.7-4.4), whereas the median OS was not reached (95% CI: 12.1 months-not reached). Multivariate analysis demonstrated that treatment with Dur/Tre as a second-line therapy or beyond was independently associated with worse PFS (HR: 1.819; 95% CI: 1.230-2.688; p = 0.003). Furthermore, an NLR of ≥ 2.56 was identified as an independent predictor of reduced OS (HR: 1.919; 95% CI: 1.033-3.566; p = 0.039). The median OS was not reached (95% CI: 12.3 months-not reached) in patients with an NLR of < 2.56, compared with 12.1 months (95% CI: 9.0 months-not reached) in those with an NLR of ≥ 2.56 (p = 0.016). A Sankey diagram illustrating post-treatment outcomes revealed that a significantly larger proportion of patients with high NLRs did not proceed to subsequent therapies but instead received best supportive care (p = 0.046). Spline curve analysis showed that an NLR range of approximately 2.3-3.0 represents an appropriate cut-off for predicting OS.

The NLR is a significant prognostic biomarker for OS in patients with HCC treated with Dur/Tre.
