Treatment for cancer-associated superficial vein clots

Prospective Evaluation of the Treatment of Cancer Associated Superficial Venous

Observational Centre Hospitalier Universitaire, Amiens · NCT07210671

This project will see if different blood-thinning treatments given to adults with active cancer and recent superficial vein clots lead to better outcomes.

What this trial studies

This is a prospective observational cohort at CHU Amiens enrolling adults with Doppler-confirmed superficial venous thrombosis and active cancer. Investigators will record which anticoagulant regimens clinicians choose in routine care for SVT diagnosed within the prior month. Patients will be followed for clinical outcomes such as clot progression, new deep vein thrombosis or pulmonary embolism, bleeding events, and changes in therapy. The collected data will be used to describe associations between real-world treatment choices and patient outcomes to inform future recommendations.

Who should consider this trial

Good fit: Adults (18+) with active cancer and a Doppler-confirmed superficial venous thrombosis within the past month who speak French and have social security coverage are ideal candidates.

Not a fit: Patients with concomitant pulmonary embolism or proximal/deep vein thrombosis, those already on anticoagulation for another reason, legally protected adults, or those with contraindications to anticoagulation are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, results could help doctors choose safer and more effective anticoagulation for cancer patients with superficial vein clots.

How similar studies have performed: Randomized trials have established anticoagulation approaches for cancer-associated deep vein thrombosis, but prospective data specifically on cancer-associated superficial venous thrombosis are sparse and largely lacking.

Eligibility criteria

* Detectable tumor disease, cancer treatment within the last 6 months, ongoing hormone therapy for cancer, palliative cancer.
* The patient has received potentially non-curative cancer treatment (notably palliative chemotherapy).
