Cancer Patients' blood clot care under the microscope
NCT ID NCT03407469
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study follows 260 cancer patients who are on long-term blood thinners for blood clots (VTE). Researchers will ask participants about their quality of life, how well they stick to their medication, and their healthcare costs over 12 months. The goal is to learn what helps or hinders treatment, not to test a new drug.
