Glasgow prognostic score predicts efficacy and prognosis in patients with advanced non-small cell lung cancer receiving EGFR-TKI treatment.

Abstract：

BACKGROUND:Lung cancer is the leading cause of cancer-related deaths. Although epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) are effective for advanced non-small cell lung cancer (NSCLC) harboring EGFR mutations, some patients experience little or no response. The Glasgow prognostic score (GPS) is an inflammation-related score based on C-reactive protein (CRP) and albumin concentrations, and has prognostic value in various cancer settings. This study aimed to evaluate whether GPS could predict response of NSCLC to EGFR-TKIs. METHODS:This retrospective multicenter study evaluated patients with NSCLC harboring EGFR mutations who received EGFR-TKI monotherapy from October 2006 to December 2016. GPS values were determined using CRP and albumin concentrations from before initiation of EGFR-TKIs. The Kaplan-Meier method and Cox proportional hazard models were used to evaluate progression-free survival (PFS) and overall survival (OS). RESULTS:In 214 patients, 141, 43, and two patients had GPS values of 0, 1, and 2, respectively. The GPS independently predicted the efficacy of EGFR-TKIs; good GPS (0-1) conferred significantly better PFS (hazard ratio [HR]: 0.59, 95% confidence interval [CI]: 0.38-0.96, P = 0.03) and OS (HR: 0.56, 95% CI: 0.33-0.96, P = 0.03). Multivariate analysis confirmed that a good GPS (0-1) independently predicted good PFS and OS among patients who had PS of 0-1. Good GPS (0-1) independently predicted good OS among patients receiving treatment in first-line settings. CONCLUSIONS:The GPS independently predicted the efficacy of EGFR-TKIs for EGFR-mutated NSCLC; however, further studies are needed to validate our findings. KEY POINTS:SIGNIFICANT FINDINGS OF THE STUDY: Glasgow prognostic score (GPS) independently predicted the efficacy of epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) treatment for EGFR-mutated NSCLC. WHAT THIS STUDY ADDS:The findings presented in this paper will help to identify patients who will be expected to experience limited or no response to EGFR-TKI treatment by using GPS.
