NCT ID NCT03297034
First seen Jun 29, 2026 · Last updated Jun 30, 2026 · Updated 1 time
Summary
This study follows people who survived childhood cancer for at least five years to learn about the long-term effects of the disease and its treatment. Researchers send questionnaires to survivors to gather information on quality of life, physical and mental health, medication use, and education. The goal is to use these findings to improve follow-up care and treatment for future patients.
