Summary
Brief summary (as posted)
Occult metastasis at the time of surgery is a major driver of poor outcomes in intrahepatic cholangiocarcinoma (ICC), yet reliable preoperative biomarkers to identify such patients are lacking. The EXOMIC study aims to develop and validate a circulating exosomal microRNA (exo-miRNA)-based liquid biopsy assay to detect occult metastasis preoperatively in patients with resectable ICC.

- Training Cohort - ICC with Occult Metastasis
- description
- The cohort of ICC patients who had occult metastasis detected at the time of surgery. Preoperative samples were analyzed using the EXOMIC qRT-PCR assay to validate candidate exosomal microRNAs identified in the discovery cohort.
- interventionNames
- Diagnostic Test: EXOMIC assay (qRT-PCR validation)
- label
- Training Cohort - ICC without Occult Metastasis
- description
- The cohort of ICC patients without occult metastasis at the time of surgery. Preoperative samples were analyzed with the EXOMIC qRT-PCR assay to evaluate differential miRNA expression and refine the predictive model for occult metastasis detection.
- interventionNames
- Diagnostic Test: EXOMIC assay (qRT-PCR validation)
- label
- Validation Cohort - ICC with Occult Metastasis
- description
- The cohort of ICC patients with occult metastasis at the time of primary tumor resection. The EXOMIC qRT-PCR assay was applied to confirm the predictive value of the exosomal miRNA panel in identifying occult metastasis prior to surgery.
