CAYA Cancer Prospective Cohort Study

3 juni 2026 bijgewerkt door: Resonance, Inc.

Improving Cancer Outcomes for Children, Adolescents, and Young Adults: A Multicenter Prospective Cohort Study on Treatment Failure and Toxicity in Low- and Middle-Income Countries.

Cancer is a leading cause of illness and death among children, adolescents, and young adults(CAYAs), especially in low- and middle-income countries(LMICs), where access to timely diagnosis and treatment is often limited. As a result, patients in these settings may experience higher rates of treatment complications, interruptions, and poorer outcomes compared with those in high-income countries (HICs).

This is a prospective, multicenter observational study that will follow children, adolescents, and young adults(CAYAs) with cancer who are receiving routine care at participating hospitals in low - and middle - income countries(LMICs). The study does not involve experimental treatments or changes to standard medical care. Information will be collected from medical records and from questionnaires that address access to care and social factors affecting treatment.

By describing treatment outcomes and the challenges patients and families face during cancer care, this study aims to provide data that can help inform future efforts to improve access to care and cancer outcomes in resource-limited settings.

Studie Bevolking

The study population consists of children, adolescents and young adults aged 0 to 21 years diagnosed with cancer, who are receiving routine clinical care at participating hospitals in low- and middle-income countries(LMIC). Participants are enrolled prospectively and followed over time as part of an observational cohort to document clinical outcomes and factors related to access to care.

Beschrijving IPD-plan

At this stage, the plan for sharing individual participant data (IPD) remains undecided. As the study continues to expand to new sites and additional countries, a comprehensive assessment of applicable data protection and privacy regulations in each jurisdiction is required. A final determination regarding IPD sharing will be made once compliance with all relevant national and international legal frameworks has been ensured.
