Risk factors and nomogram prediction model establishment of perioperative blood transfusion in pa-tients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic surgery
Objective To explore the risk factors of perioperative blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic surgery,and construct a nomogram predic-tion model.Methods A retrospective analysis was conducted on the clinical data of 262 patients who un-derwent the nasal endoscopic surgery from January 2021 to May 2023.The patients were divided into two groups according to perioperative blood transfusion or not:non-transfusion group and transfusion group.Uni-variate and multivariate logistic regression were conducted to identify independentrisk factors of perioperative blood transfusion,and a nomogram prediction model was developed.The receiver operating characteristic(ROC)curve was drawn,and the area under the curve(AUC)was calculated.Results The incidence of blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic surgery was 46(17.6％).Multivariate logistic regression analysis revealed that preoperative hemoglobin level 70 to＜100 g/L(OR=6.178,95％CI 2.271-16.805,P＜0.001),preoperative albumin level 25 to＜35 g/L(OR=2.126,95％CI 1.021-4.424,P=0.044),and classification of surgery grade Ⅲ or Ⅳ (OR=4.725,95％CI 1.634-13.584,P=0.004)were independent risk factors for predicting perioper-ative blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endoscopic sur-gery.The AUC of the nomogram model was 0.769(95％CI 0.701-0.838),the sensitivity was 67.6％,and the specificity was 76.1％.Conclusion Preoperative hemoglobin level 70 to＜100 g/L,preoperative albumin level 25 to＜35 g/L,and classification of surgery grade Ⅲ or Ⅳ are independent risk factors of perioperative blood transfusion in patients with recurrent nasopharyngeal carcinoma undergoing nasal endo-scopic surgery.The nomogram model established based on the above risk factors has good predictive ability for perioperative blood transfusion.
