A Novel Serological Risk Model for Early Non-invasive Diagnosis of Cholangiocarcinoma

A reliable and accurate preoperative tool capable of early diagnosing malignant cholangiocarcinoma is lacking and urgently needed for clinical practice. This study proposes to establish and evaluate a novel serological risk model on blood samples for non-invasively diagnosing cholangiocarcinoma. The study includes the construction of capable novel serological risk model and the validation of the diagnosis model.
