Abstract

Background: There are few diagnostic tools that can be used to determine which patient with intrahepatic cholangiocarcinoma (ICC) can benefit from surgery actually, highlighting that the need for new preoperative stratification strategies. The aim of this study was to investigate the predictive values of preoperative biomarkers in survival analyses for patients with ICC after surgical resection.

Methods: A total of 285 patients with ICC were retrospectively reviewed. Receiver operating charateristics (ROC) curves were used to evaluate the predictive effects of preoperative carbohydrate antigen 19-9 (CA19-9) with different cutoff values and carcinoembryonic antigen (CEA) in patients with ICC.

Results: Preoperative CA19-9 with a cutoff value of 200 U/ml performed better in predicting overall survival (OS) and progression free survival (PFS) in ICC patients. Patients with preoperative CA19-9 value > 200 U/ml generally had a poor surgical response. However, surgical resection could also benefit patients whose CA19-9 levels decreased postoperatively or preoperative CEA levels were negative.

Conclusions: With the cutoff value of 200U/ml, CA19-9 was a better preoperative biomarker for predicting survival for ICC patients after surgical resection. Combination of preoperative CA19-9 and CEA showed the strongest predictive power in survival analyses in these patients and should be recognized in daily clinical care.
