A high Glasgow prognostic score (GPS) or modified Glasgow prognostic score (mGPS) predicts poor prognosis in gynecologic cancers: a systematic review and meta-analysis

Abstract

The Glasgow Prognostic Score or modified Glasgow Prognostic Score (GPS/mGPS), a novel inflammatory indicator, which acts as a prognostic predictor in various cancers. However, these results are still controversial. In this meta-analysis, we aimed to investigate the prognostic role of GPS/mGPS in patients with gynecologic cancers. We explored eligible studies by searching the databases PubMed, the Cochrane Library, EMBASE, and Web of Science. The hazard ratio (HR) and odds ratios (OR) with 95% confidence intervals (CIs) were extracted to investigate the correlation between GPS/mGPS and overall survival (OS) and progression-free survival (PFS). Additionally, we performed subgroup analyses to detect the potential heterogeneity in our study. 11 studies involving 2830 patients were enrolled in this meta-analysis. The results revealed that a high GPS was significantly related to a shorter OS (pooled HR = 1.94; 95% CI = 1.54-2.43; P < 0.001) and PFS (pooled HR = 1.92; 95% CI = 1.56-2.35; P < 0.001) in patients with gynecologic cancers. Moreover, mGPS also predicted poor OS (pooled HR = 1.67; 95% CI = 1.41-1.96; P < 0.001) and PFS (pooled HR = 1.73; 95% CI = 1.47-2.04; P < 0.001) in gynecologic cancers patients. A higher GPS/mGPS is correlated with poor survival outcomes in patients with gynecologic cancers. Pretreatment GPS/mGPS is a valid prognostic predictor in gynecologic cancers.
