Evaluation of diagnostiC Capacity of eccDNAs as Biomarkers in Indetermined biLiary Stricture(ECCBILE) (ECCBILE)

May 22, 2025 updated by: Peking University Third Hospital

Evaluation of diagnostiC Capacity of eccDNAs as Biomarkers in Indetermined biLiary Stricture(ECCBILE): a Prospective Cohort Study

Biliary stricture is mainly malignant in the adults and caused by several types of fatal malignancies such as pancreatic cancer, cholangiocarcinoma, and metastatic tumor, which have poor prognosis that the overall survival of unresectable lesions is no more than 15 months. The poor outcome often relates to a lack of reliable strategies for early diagnosis, which results in most patients with malignant biliary stricture being already advanced-stage disease at presentation. Therefore, it is critical to discover novel and effective strategies for the early diagnosis of malignant biliary strictures.

Brush cytology and biopsy during endoscopic retrograde cholangiopancreatography (ERCP) are the main methods for recognizing malignant diseases of the bile duct, but their sensitivity is relatively low, 45% and 48.1%, respectively. Even when combined with other biomarkers like carbohydrate antigen 19-9 (CA19-9), their sensitivity is still less than 80%.

In the previous study, the investigators found that bcf-eccDNA has excellent diagnostic value in predicting uncertain bile duct stricture, and the sensitivity and specificity of a related eccDNA in 40 samples are 80.8% and 100%. The sensitivity and specificity of another eccDNA were 92.3% and 92.9%, respectively. However, the sample size is still relatively small, and further prospective studies are needed to evaluate its diagnostic efficacy.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Patient is diagnosed with malignant disease from biliary system
Time Frame: in one year
Malignant tumor is confirmed by histopathology or cytopathology. If the pathology is unclear or inaccessible, 2 gastroenterologists will finally confirm the diagnosis of the bile duct stricture after 1 year follow-up.
