ABSTRACT
OBJECTIVE:
Chemoradiation (CRT) may induce a change in systemic inflammatory state which could affect clinical outcomes in oesophageal cancer. We aimed to evaluate the changes and prognostic significance of systemic inflammatory markers following definitive CRT in oesophageal squamous cell carcinoma.METHODS:
A total of 53 patients treated with concurrent CRT were included in this retrospective analysis. We compared neutrophils, lymphocytes, platelets, neutrophil-lymphocyte ratio (NLR) and platelet-lymphocyte ratio (PLR) before and after CRT using Wilcoxon signed-rank test. Overall survival (OS) and progression-free survival (PFS) were calculated. Univariable and multivariable survival analysis were performed using Cox regression analysis. Clinical univariable survival prognostic factors with p < 0.1 were included in a multivariable cox regression analysis for backward stepwise model selection.RESULTS:
Both NLR (median ∆+2.8 [IQR -0.11, 8.62], p < 001) and PLR (median ∆+227 [81.3-523.5], p < 0.001) increased significantly after CRT. Higher levels of pre-CRT, post-CRT and change (∆) in NLR and PLR were associated with inferior OS and PFS. Post-CRT NLR (HR 1.04, 95% CI 1.02-1.07, p < 0.001), post-CRT platelets (HR 1.03, 95% CI 1.01-1.05, p = 0.005), cT-stage (HR 3.83, 95% CI 1.39-10.60, p = 0.01) and RT dose (HR 0.41, 95% CI 0.21-0.81, p = 0.01) were independent prognostic factors for OS in multivariable analysis. Change in NLR (HR 1.04, 95% CI 1.01-1.06, p = 0.001), post-CRT platelets (HR 1.03, 95% CI 1.01-1.05, p = 0.002), cT-stage (HR 3.98, 95% CI 1.55-10.25, p = 0.004) and RT dose (HR 0.41, 95% CI 0.21-0.80, p = 0.009) were independent prognostic factors for PFS.CONCLUSION:
Both NLR and PLR increased following definitive CRT. Post-CRT NLR and ∆NLR were associated with adverse survival in oesophageal SCC. ADVANCES IN KNOWLEDGE We showed that CRT increased PLR and NLR, possibly reflecting a systemic inflammatory state which were associated with poor clinical outcomes in oesophageal SCC.
