Abstract
BACKGROUND: The prognostic nutritional index (PNI) has been found to have prognostic value in several cancers, and we aimed to determine its predictive value for the long-term prognosis of cervical esophageal squamous cell carcinoma (CESCC) patients treated with chemoradiotherapy (CRT). METHODS: The data for 106 CESCC patients who received radiotherapy with or without chemotherapy at the Cancer Hospital of Fujian Medical University from June 1, 2000 to December 31, 2015 were retrospectively analyzed. According to serum measurements taken before therapy, the PNI was calculated as albumin (g/L) + 5 × total lymphocyte count. The association between PNI and overall survival (OS) was determined by the Kaplan-Meier method and Cox proportional regression model analysis. RESULTS: The median follow-up time was 19 months. The optimal cutoff value for PNI was calculated to be 48.15, and patients were divided into a low PNI group (<48.15) and high PNI group (≥48.15). Univariate analysis showed that a low survival rate was significantly associated with male gender (P=0.004), tumor length ≥5.0 cm (P=0.043), radiotherapy technique (P=0.016), synchronous chemotherapy (P=0.012), lymphocyte-monocyte ratio (LMR) (P=0.007), neutrophil-lymphocyte ratio (NLR) (P=0.007), lung cancer inflammation index (ALI) (P=0.008), cervical esophageal carcinoma inflammation index (CEI) (P=0.043), and PNI (P<0.001). The OS was higher in the high PNI group than in the low PNI group. On multivariate analysis, gender (P=0.004), radiotherapy technique (P=0.029), and PNI (P=0.007) were independent prognostic factors in CESCC treated with CRT. CONCLUSIONS: The PNI value is a simple, reliable, and reproducible indicator for improving the accuracy of patient prognosis. And larger-scale studies are warranted to validate these findings.
