CAYA Cancer Prospective Cohort Study
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.

Children, Adolescents, and Young Adults With Cancer
Participants include children, adolescents and young adults with a diagnosis of cancer who are receiving routine care at participating hospitals in low- and middle-income countries(LMIC).
This study follows patients as part of a single observational cohort and does not assign any experimental treatments.
All medical care is provided according to local standard practice.
Participants are followed over time to document clinical outcomes, as well as factors related to access to care and the overall treatment experience.
