Abstract
Background
Recent studies from eastern centers have demonstrate an association between inflammatory response and long-term outcomes after hepatocellular carcinoma (HCC) resection. However, the prognostic impact of inflammatory markers in western patients, with distinct tumor and epidemiologic features, is still unknown.
Aim
To evaluate the prognostic impact of preoperative neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR), as well as their impact according to tumor size (< 5 cm, 5-10 cm, > 10 cm) in patients undergoing HCC resection with curative intent.
Methods
Optimal cut-off values for NLR, PLR, and MLR were determined by plotting the receiver operator curves. Overall survival (OS) and disease-free survival (DFS) curves were calculated using the Kaplan-Meier method and compared using the log-rank test. The Cox method was used to identify independent predictors of OS and DFS.
Results
In total, 161 consecutive adult patients were included. A high NLR (>1.715) was associated with worse OS (P=0.018). High NLR (>2.475; P=0.047) and PLR (>100.25; P=0.028) were predictors of short DFS. In HCC < 5 cm, MLR (>1.715) was associated with worse OS (P=0.047). In the multivariate analysis, high PLR was an independent predictor of worse DFS (hazard ratio [HR]=3.029; 1.499-6.121; P=0.002).
Conclusions
Inflammatory markers are useful tools to predict long-term outcomes after liver resection in western patients, high NLR was able to stratify subgroups of patients with short OS and DFS, an increased PLR was an independent predictor of short DFS, while high MLR was associated with short OS in patients with early HCC.
