ABSTRACT
Objective:To evaluate the prognostic factors for duodenalpapilla carcinoma (DPC)treated by pancreatoduodenectomy (PD).Methods:Clinicopathological data of 68 patients with duodenalpapilla carcinoma who undergone PD and finally diagnosed by surgery and histopathology from January 2001 to June 2010 were retrospectively analyzed.The patients were followed-up until 2015.Survival analysis was conducted using the Kaplan-Meier survival and Cox proportional hazards model analysis.The difference in survival curves was evaluated with a log-rank test.Results:The patients were followed-up with a median follow-up of 57 months (ranging from 4 months to 168 months).The univariate analysis showed that increased serum levels of total bilirubin were correlated with a poor prognosis,as well as a senior grade of infiltration depth,lymph node metastases,and TNM stage (P=0.043,0.003,0.004 0.002,respectively).Only increased serum levels of total bilirubin and a senior grade of TNM stage retained their significance when adjustments were made for other known prognostic factors in Cox multivariate analysis (RR=2.031,P=0.031 and RR=2.255,P=0.029).Conclusions:Increased serum levels of total bilirubin were correlated with a poor prognosis,as well as a senior grade of infiltration depth,lymph node metastases,and TNM stage.Only increased serum levels of total bilirubin and a senior grade of TNM stage can serve as independent prognosis indexes in the evaluation of patients with DPC after PD.
