Systemic inflammatory biomarkers as prognostic tools in patients with gastroesophageal adenocarcinoma

Abstract

Abstract Purpose Gastroesophageal adenocarcinoma is associated with poor prognosis, even in resectable stages. Systemic inflammation plays a key role in cancer progression. Yet, information on prognostic values of systemic inflammatory parameters in European cohorts is scarce. Methods We analysed systemic inflammatory biomarkers (neutrophil-to-lymphocyte ratio (NLR), leucocyte-to-lymphocyte ratio (LLR), platelet-to-lymphocyte ratio (PLR), systemic inflammation response index (SIRI) and modified Glasgow Prognostic Score (mGPS)) at the time of cancer diagnosis and their association with overall survival (OS) in patients with gastroesophageal adenocarcinoma treated at the Medical University of Vienna between 1990 and 2020. Results In this analysis of 769 patients with gastroesophageal adenocarcinoma, higher mGPS (0–2) scores were associated with shorter OS in the overall cohort (24.9 versus 11.9 versus 7.6 months; HR 1.74, 95% CI 1.549–1.056; p < 0.001), in locally advanced (31.1 versus 19.8 versus 13.9 months, HR 1.561, 95% CI 1.274–1.912; p < 0.001) and in advanced/metastatic settings (12.3 versus 7.3 versus 5.8 months; HR 1.377, 95% CI 1.777–1.611; p < 0.001). In multivariate analyses, the association of mGPS with the OS stayed statistically significant in the locally advanced cohort (HR 1.397, 95% CI 1.068–1.828; p = 0.015), whereas NLR, LLR, PLR and SIRI did not. mGPS was associated with more advanced stages (p < 0.001) and weight loss (p = 0.002). Conclusion mGPS poses a feasible prognostic tool in patients with locally advanced gastroesophageal cancer.
