    Abstract:
    Serum carbohydrate antigen 125 (CA125) is associated with the prognosis of various malignancies, including ovarian and pancreatic cancer. The relationship between preoperative serum CA125 level and the survival of patients with intrahepatic cholangiocarcinoma (ICC) has not been fully studied. The aim of this study was to explore the prognostic value of CA125 in ICC after hepatectomy. We retrospectively reviewed the clinicopathological data of 178 ICC patients who underwent hepatic resection. Receiver operating characteristic analyses were performed to estimate the relationships of serum CA125, α-fetoprotein, carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9 with the prognosis of ICC. The predictive value of CA125 for the prognosis of ICC patients was demonstrated by univariate analyses and Cox proportional hazards models. CA125 was correlated with tumor size, differentiation, capsulation, tumor node-metastasis stage, recurrence, and CEA. Univariate analysis indicated that CA125, sex, tumor number, tumor size, differentiation, surgical resection margin, tumor node metastasis stage, and CEA were risk factors for both the overall survival and the disease-free survival of ICC patients. Cox proportional hazards models showed that preoperative elevated CA125, a tumor size > 5 cm, and an R1 surgical resection margin were independent prognostic predictors of overall survival and disease-free survival. CA125 also had strong predictive value for the prognosis of different ICC subgroups, including patients without lymph node metastasis and with elevated carbohydrate antigen 19-9 levels. Preoperative elevated serum CA125 level is a noninvasive, simple, and reliable indicator of the prognosis of ICC patients after hepatectomy.
