Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Primary Outcome Measure
1. Incidence of treatment failure, dichotomous: Defined as the first occurrence of relapse, progressive disease, refractory disease, treatment-related death, diseaserelated death, treatment abandonment, or secondary malignancy; summarized as the 3-year cumulative incidence of the event. 2. Incidence of severe treatment-related toxicity (CTCAE v5.0), dichotomous: Defined as the first occurrence of any grade 3, 4 or 5 adverse event according to CTCAE 5.0; summarized as the 3-year cumulative incidence of the event.
From enrollment through 36 months of follow-up

Study Arms (1)
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.
Eligibility Criteria
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.
You may qualify if:
- Subjects must meet all the following criteria to be included in this study:
- Age 0 to 21 years at study enrollment.
- Diagnosed with cancer and receiving active treatment or undergoing follow-up at the participating sites.
- a. Note: Patients seen solely for consultation or diagnostic evaluations without subsequent treatment and those who have been off treatment for more than 5 years and are seen only for survivorship follow-up are not considered as meeting this criterion.
- Willingness to provide informed consent/assent. For minors incapable of providing assent, or individuals unable to provide consent, consent must be obtained from a legal representative and in accordance with local requirements.
You may not qualify if:
- Subjects meeting any of the following criteria must be excluded from this study:
- \. Any medical or psychological condition that, in the investigator's opinion, might compromise the ability of the patient to provide assent/informed consent/assent.
