BACKGROUND Naples prognostic score (NPS) is a scoring system based on albumin, cholesterol concentration, lymphocyte-to-monocyte ratio, and neutrophil-to-lymphocyte ratio reflecting host systemic inflammation, malnutrition, and survival for several malignancies. This study was designed to assess the prognostic significance of NPS in patients with locally advanced esophageal squamous cell carcinoma (ESCC) and to compare its prognostic accuracy with that of other systemic inflammatory and nutritional index. METHODS We retrospectively examined 165 patients with locally advanced ESCC who underwent neoadjuvant therapy followed by curative resection between January 2011 and September 2019. Patients were divided into three groups based on their NPS before neoadjuvant therapy (Group 0: NPS = 0; Group 1: NPS = 1-2; Group 2: NPS = 3-4). We compared the clinicopathological characteristics and survival rates among the groups. RESULTS The 5-year recurrence-free survival (RFS) and overall survival (OS) rates were significantly different between the groups (P < 0.001). The NPS was superior to other systemic inflammatory and nutritional index for predicting prognoses, as determined using area under the curves (P < 0.05). Multivariate analysis demonstrated that the NPS was a significant predictor of poor RFS (Group 1: hazard ratio [HR] 1.897, P = 0.049; Group 2: HR 3.979, P < 0.001) and OS (Group 1: HR 2.152, P = 0.033; Group 2: HR 3.239, P = 0.006). CONCLUSIONS The present study demonstrated that NPS was an independent prognostic factor in patients with locally advanced ESCC and more reliable and accurate than the other systemic inflammatory and nutritional index.
