Predicting arterial thrombosis in cancer patients

A Predictive Score for Arterial Thrombosis Associated With Cancer. The Prospective COMPASS- Arterial Cancer Associated Thrombosis Study

National and Kapodistrian University of Athens · NCT05256329

This study is trying to find out what factors can help predict the risk of blood clots in the arteries for cancer patients starting or undergoing treatment.

What this trial studies

This observational study aims to identify clinical predictors of arterial thrombosis in ambulatory patients with specific types of cancer who are starting or have already begun anticancer treatment. It focuses on understanding the relationship between cancer and arterial thrombotic events, which have been less studied compared to venous thromboembolic events. By evaluating various risk factors, including cancer type and patient history, the study seeks to improve risk assessment models for arterial thrombosis in this population. The findings could lead to better management strategies for patients at risk of these complications.

Who should consider this trial

Good fit: Ideal candidates include ambulatory adults with histologically confirmed solid cancers or specific hematologic malignancies.

Not a fit: Patients under 18 years old, with a life expectancy of less than 3 months, or those with recent arterial thromboembolism may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance the ability to predict and prevent arterial thrombosis in cancer patients, potentially reducing morbidity and mortality.

How similar studies have performed: While the relationship between cancer and venous thromboembolic events has been extensively studied, the focus on arterial thrombosis in cancer patients is less established, making this approach relatively novel.
