Abstract


Background: Inflammation-based prognostic scores, including Glasgow prognostic score (GPS), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), systemic immune-inflammation index (SII) and advance lung cancer inflammation index (ALI) are reported to be associated with survival in patients with non-small cell lung cancer (NSCLC). However, at present, there are no studies that compared these scoring systems for resectable NSCLC.

Methods: Three hundred forty-one NSCLC patients who underwent surgery at our institution were included. The optimal cut-off values of SII and ALI were calculated by the Cutoff Finder. The area under the receiver operating characteristics curve (AUC) was calculated to compare the predictive ability of each of the scoring systems. Univariate and multivariate analyses were performed to identify the clinicopathological variables associated with overall survival.

Results: The optimal cut-off value of SII and ALI were 471.2 × 109/L and 37.66, respectively. All scores were significantly related to the 5-year cancer-specific survival. The ALI consistently had a higher AUC value in comparison with other inflammation-based prognostic scores. A multivariate analysis showed that GPS and ALI were independently associated with overall cancer-specific survival.

Conclusion: To the best of our knowledge, this is the first study to demonstrate that GPS and ALI appear to be superior to other inflammation-based prognostic scores in patients undergoing potentially curative resection for NSCLC.
