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.

Project description:PurposeWe aimed to evaluate whether the addition of pemetrexed is effective in improving progression-free survival (PFS) in epidermal growth factor receptor (EGFR)-mutated patients with or without concomitant alterations.Materials and methodsThis multicenter clinical trial was conducted in China from June 15, 2018, to May 31, 2019. A total of 92 non-small cell lung cancer (NSCLC) patients harboring EGFR-sensitive mutations were included and divided into concomitant and non-concomitant groups. Patients in each group were randomly treated with EGFR-tyrosine kinase inhibitor (TKI) monotherapy or EGFR-TKI combined with pemetrexed in a ratio of 1:1. PFS was recorded as the primary endpoint.ResultsThe overall median PFS of this cohort was 10.1 months. There were no significant differences in PFS between patients with and without concomitant and between patients received TKI monotherapy and TKI combined with pemetrexed (p=0.210 and p=0.085, respectively). Stratification analysis indicated that patients received TKI monotherapy had a significantly longer PFS in non-concomitant group than that in concomitant group (p=0.002). In concomitant group, patients received TKI combined with pemetrexed had a significantly longer PFS than patients received TKI monotherapy (p=0.013). Molecular dynamic analysis showed rapidly emerging EGFR T790M in patients received TKI monotherapy. EGFR mutation abundance decreased in patients received TKI combined chemotherapy, which supports better efficacy for a TKI combined chemotherapy as compared to TKI monotherapy. A good correlation between therapeutic efficacy and a change in circulating tumor DNA (ctDNA) status was found in 66% of patients, supporting the guiding role of ctDNA minimal residual disease (MRD) in NSCLC treatment.ConclusionEGFR-TKI monotherapy is applicable to EGFR-sensitive patients without concomitant alterations, while a TKI combined chemotherapy is applicable to EGFR-sensitive patients with concomitant alterations. CtDNA MRD may be a potential biomarker for predicting therapeutic efficacy.
