Abstract

The aim of this study was to interrogate whether blood-borne inflammatory and nutritional markers predict long-term survival and response to neoadjuvant chemotherapy in radically treated oesophagogastric cancer patients. This retrospective study included 246 patients who underwent oesophageal resection for high-grade dysplasia or carcinoma between 2005 and 2010. The predictive value of routine preoperative immunonutritional blood tests was assessed for their association with survival and response to chemotherapy. On multivariate analysis, higher neutrophil–lymphocyte ratio (NLR) (p < 0.0001), N stage (p < 0.0001) and perineural invasion (p < 0.0001) were associated with poor overall survival. Regarding disease-free survival, multivariate analysis showed reduced serum albumin (p = 0.034), N stage (p < 0.0001), M stage (p = 0.037), vascular invasion (p < 0.0001) and presence of R1 resection (p = 0.003) to correlate with earlier recurrence. In those who received neoadjuvant chemotherapy, analysis of prechemotherapy characteristics showed only serum albumin (p = 0.037) to predict pathological response to chemotherapy. Preoperative immunonutritional markers, NLR and albumin, were independent prognostic markers for overall survival and disease-free survival, respectively, after oesophageal cancer resection. Prospective studies evaluating the role of immunonutritional modulation to improve response to chemotherapy and long-term outcome are required.
