Correlation between neutrophil/lymphocyte ratio, platelet/lymphocyte ratio and postoperative cognitive dysfunction in elderly patients with esophageal cancer
Notice bibliographique
Résumé
The present study intends to investigate the correlation between neutrophil/lymphocyte ratio (NLR), platelet/lymphocyte ratio (PLR) and postoperative cognitive dysfunction (POCD) in elderly patients with esophageal cancer. Elderly patients >65 years old with esophageal cancer in our department from October 2017 to June 2021 were included in the study. The cognitive function of the patients was assessed by the mini-mental state examination (MMSE) Scale at 1day, 3 days, and 7days after surgery. POCD was considered when the scores were <27 points, and the remaining patients were included in the control group. A total of 104 elderly patients with esophageal cancer were included in this study, and 24 patients developed POCD, with an incidence of 23.1%. The expression of NLR and PLR in both 2 groups was increased on the 1st postoperative day compared with that before surgery. There was no significant difference in the expression of NLR and PLR between the 2 groups before operation, but the expression of both in the POCD group was significantly higher than that in the control group after operation (P < .05). Logistic regression analysis showed that smoking, postoperative NLR and postoperative PLR were independent risk factors for POCD. Spearman test showed that NLR was negatively correlated with MMSE scores at postoperative 1 day and 3 days (P < .05), while PLR was negatively correlated with MMSE scores at postoperative 1 day, 3 days and 7 days (P < .05). The Area Under receiver operating characteristic curve (AUC) of postoperative NLR for predicting POCD in elderly patients with esophageal cancer was 0.656, and the AUC of postoperative PLR was 0.722. After combination of NLR and PLR, the AUC increased to 0.803 with the sensitivity of 66.7% and specificity of 82.5%. The expression level of postoperative NLR and PLR in elderly patients with esophageal cancer combined with POCD is significantly increased, which is associated with postoperative cognitive impairment. Moreover, the combination of NLR and PLR has a good predictive ability for POCD, which could be used as a potential biomarker for early diagnosis of POCD.
