Understanding bleeding risks in patients with blood cancers

Bleeding in Thrombocytopenia Explained

Observational Sanquin-LUMC J.J van Rood Center for Clinical Transfusion Research · NCT03505086

This study is trying to find out which blood cancer patients are more likely to bleed during chemotherapy so that doctors can better prevent and manage these risks.

What this trial studies

This multicenter case cohort study investigates clinical risk factors and biomarkers associated with bleeding in hemato-oncology patients undergoing intensive chemotherapy. The study aims to identify patients at high and low risk for bleeding events, which could lead to more effective transfusion strategies and treatment approaches. Participants will complete a questionnaire about previous bleeding events and provide blood and urine samples for analysis. The goal is to improve the prediction and prevention of bleeding in this vulnerable patient population.

Who should consider this trial

Good fit: Ideal candidates include hemato-oncology patients aged 18 and older who are expected to become thrombocytopenic and may require prophylactic platelet transfusions.

Not a fit: Patients with myeloproliferative disorders will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more tailored and effective treatments for preventing bleeding in hemato-oncology patients.

How similar studies have performed: While there have been studies on bleeding risks in similar populations, this specific approach to identifying risk factors and biomarkers is novel.
