Abstract:
Objective:To establish a preoperative forecasting model for the nature of duodenal papillary tumors and to discuss its main predictors.Methods:A case-control study was conducted;the case group included patients with malignant duodenal papillary tumors and the control group included patients with benign duodenal papillary tumors.All the patients were from Changhai Hospital. Data of patients,including the demographic characteristics,clinical symptoms during onset,laboratory findings,and radiological data, were collected by face-to-face interviews or by reviewing the medical history.Chi-square,t-test or ANOVA were employed to performed univariate analysis.All factors with P values less than or equal to 0.25 in the univariate analysis were used as independent variables for multivariate analysis,and a Logistic regression forecasting model for the nature of duodenal papillary tumors was established.Results: Totally 199 patients with pathologically-confirmed duodenal papillary tumors were included in the present study,with 166 in the case group and 33 in the control group.Multivariate analysis showed that hemoglobin(Hb),total bilirubin(Tbil),direct bilirubin(Dbil), aspartate transferase(AST),alkaline phosphatase(AKP),gamma glutamyl transpeptidase(GGT),and carcinoembryonic antigen(CEA) were independent predictors for nature of duodenal papillary tumors,with their odds ratios(95% confidence interval)being 0.981 (0.959,1.003),0.867(0.794,0.948),1.207(1.075,1.355),1.028(1.008,1.048),0.996(0.992,1.000),1.002(1.000,1.004),and 0.974(0.953,0.994),respectively.Conclusion:The Logistic regression model,which takes into consideration of Hb,Tbil,Dbil,AST, AKP,GGT,and CEA,can be used to predict the nature of duodenal papillary tumors,and its clinical value need to be further studied.
