A COMPREHENSIVE BIOMARKER EVALUATION IN BILIARY TRACT CANCER

Not Yet RecruitingN/A

Sponsor: MedSIR

Conditions: Biliary Tract Cancer (BTC)

Interventions: No intervention

The REVEAL-BTC Study will analyze 5 biomarkes in samples of participants who in the past 15 year have been diagnosed with any stage of biliary tract cancer. The expression levels of the biomarkers will be correlated with clinical outcomes in the participants, which will lead to better patient stratification that will help guide the use of targeted therapies in the future.

Sex: ALL

Age: 18 Years to —

Study type: OBSERVATIONAL

Eligibility criteria

Inclusion Criteria:

1. Written informed consent for the use of clinical data and tissue samples is available. (The use of data and samples without consent is only possible if exemption is granted by the corresponding Institutional Review Board - IRB).
2. Histologically confirmed diagnosis of biliary tract cancer (including gallbladder carcinoma \[GBC\] or cholangiocarcinoma \[CCA\]), regardless of disease stage.
3. Diagnosis must have been established within the last 15 years prior to Study initiation.
4. Availability of archival formalin-fixed paraffin-embedded (FFPE) tumor tissue sample, collected prior to Study inclusion at any disease stage (e.g., during surgery or in the advanced setting). For patients with de novo metastatic disease or early stage primary tumors undergoing surgery, the tissue must have been obtained before the initiation of any systemic therapy (e.g. chemotherapy) or radiotherapy. For patients with recurrent disease undergoing a new biopsy, previous treatments are allowed.
5. Availability and accessibility of basic clinical information and survival data on medical records.

Exclusion Criteria:

1. Unavailability or inadequate quality (e.g., insufficient tumor content, degraded tissue) of archival FFPE tumor tissue samples for the planned immunohistochemical analysis.
2. Missing or incomplete basic clinical and/or survival data in the medical record.
