Influence of Preoperative Nutritional Status on Patients Who Undergo Upfront Surgery for Esophageal Squamous Cell Carcinoma.

Few studies have focused on preoperative nutritional status of esophageal cancer patients eligible for upfront surgery. We aimed to investigate the association of preoperative nutritional status with prognosis of patients who undergo upfront surgery for esophageal cancer. A total of 274 patients who underwent upfront surgery for esophageal squamous cell carcinoma between January 2012 and December 2016 were eligible. Preoperative nutritional status was evaluated using prognostic nutritional index (PNI) scoring system, nutritional risk screening 2002 (NRS 2002), and controlling nutritional status. The median age was 63 years (interquartile range, 58-70) and 94.7% of patients were male. The pathological stages were Stage I-74.5% (204/274), Stage II-20.4% (56/274), and Stage III-5.1% (14/274). Multivariate analysis revealed that advanced stage, a low PNI, and a high NRS 2002 were independent predictors of overall survival. During median follow-up period of 55 mo, overall survival rates were lower in the high NRS 2002 group (P < 0.001). A high NRS 2002 score was associated with frequent postoperative complications, especially pneumonia and anastomosis site leakage (P = 0.003). The poor preoperative nutritional status with a high NRS 2002 is associated with postoperative complications as well as poor overall survival in patients with upfront surgery for esophageal cancer.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2022.2042573.
