Cancer-associated VTE: A follow-up study collecting biological samples

Official title: Establishment of a Patient-based Cohort : Cancer-related Venous Thromboembolic Disease.

Run by University Hospital, Brest · NCT06393764 · Data updated 2026-11-12

This study tests how often cancer patients who have had a VTE will experience more clots over time and gathers blood and urine samples to explore why it happens.

Is this trial a fit for you?

Likely a good fit

Adults with active cancer or undergoing cancer treatment who recently had a documented VTE and are able to consent.

Probably not a fit

Patients with very short life expectancy or those unable to participate in follow-up may not benefit from the study findings.

What this trial studies

This is a prospective, single-center observational cohort study aimed at understanding the recurrence risk and underlying mechanisms of venous thromboembolism in cancer patients. Researchers will collect blood samples at study entry and at recurrence events to build a biobank for future analyses, and urine samples annually for up to five years. The study follows patients with active cancer or those undergoing cancer treatment who recently experienced VTE, to better characterize risks, biology, and prognosis in this high-risk population. Interventions are limited to biological sample collection; no experimental therapies are used. The findings may help refine risk stratification and future research in cancer-associated VTE.

Why it matters

Potential benefit: If successful, the study could improve understanding of VTE recurrence in cancer patients and support development of better prevention and monitoring strategies.

How similar studies have gone: Prior research has shown that cancer-associated VTE is clinically significant, and biobanking approaches have yielded insights in other studies, though the specific cohort design is somewhat unique.
