Abstract
Background
Studies have revealed the impacts of various inflammatory and nutritional markers in patients with esophageal squamous cell carcinoma (ESCC). We evaluated the prognostic values of multiple inflammation- or nutrition-based markers, either alone or in combination with pStage, in ESCC patients.
Methods
In total, 360 patients undergoing upfront surgery for ESCC were retrospectively reviewed. The prognostic capabilities of 7 inflammatory and 3 nutritional parameters were investigated. Furthermore, we devised new staging systems by adding these markers to pStage and examined the prognostic abilities of our new approach. Time-dependent receiver operating characteristic curves and the areas under the curve (AUCs) were estimated to compare prognostic capabilities among the parameters.
Results
The AUCs for predicting overall survival (OS) of the prognostic nutritional index (PNI), CRP to albumin ration (CAR), lymphocyte to CRP ratio (LCR) and the Naples prognostic score (NPS) were similar to that of pStage. Notably, CAR and LCR showed high predictive capabilities for OS (AUCs; 0.627 and 0.634 for 3-year OS, respectively). New staging systems combining inflammatory or nutritional markers with pStage provided higher AUCs for predicting OS than pStage alone. In particular, NPpStage (NPS and pStage) (P = 0.03), PNpStage (PNI and pStage) (P = 0.03) and LCpStage (LCR and pStage) (P = 0.05) showed significantly higher accuracy for predicting OS than pStage alone.
Conclusions
Various inflammatory or nutritional markers, especially those derived from CRP, are useful for predicting survival outcomes of ESCC patients. The predictive capabilities of these indices were augmented when used in combination with pStage.
