Elevation of CA19-9 and CEA is associated with a poor prognosis in patients with resectable gallbladder carcinoma

The aim of this study was to determine whether a combination of the tumour markers carcinoembryonic (CEA) and carbohydrate antigen 19-9 (CA19-9) would be helpful in predicting the prognosis of patients with gallbladder carcinoma (GBC) who underwent resection. A retrospective analysis of clinico-pathological features and survival of 390 patients with GBC who were treated between January 2003 and December 2013. Time-dependent receiver operating characteristic (ROC) was used to evaluate the prognostic ability of tumour markers. Combinations of preoperative CEA and CA19-9 were tested as potential prognostic factors. The evaluation of preoperative CEA and CA19-9 showed that patients with both tumour markers within the normal range had the best prognosis with a median survival of 27 months and R0 rate of 86%. Patients with both tumour markers elevated had the poorest prognosis and lower R0 rate (p
