Who can take part
AI summary
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for children, teenagers and young adults who were diagnosed with cancer in the last 15 years and were treated at a participating centre. Their medical records are reviewed.
- Age
- 0 to 21 years at the time of diagnosis.
- Sex
- All sexes can join.
- Disease stage
- Any type of confirmed cancer, diagnosed within the 15 years before the site's activation date. The study focuses on acute lymphoblastic leukemia and lymphoblastic lymphoma.
- Earlier treatment
- Must have received substantial anti-cancer treatment at the participating center, such as chemotherapy, surgery, radiation therapy or immunotherapy.
Main reasons for not taking part
- Visited the centre only for a consultation, with no anti-cancer treatment there
- Visited the centre only for pathology, radiology or other diagnostic tests, with no treatment
- Medical records not available or not accessible for review

About the trial
What the trial wants to find out
Despite advances in cancer treatment, significant disparities in outcomes persist between high-income countries (HICs) and low-and middle-income countries (LMICs). Around 80% of children with cancer live in LMICs, where they face challenges such as delayed diagnosis, misdiagnosis, comorbidities, distance to treatment, financial barriers, and limited access to risk-adapted therapies.

Acute lymphoblastic leukemia(ALL)/lymphoblastic lymphoma(LBL), for example, is one of the greatest success stories in pediatric oncology, however, such improvements are not evenly distributed worldwide, and the outcomes for leukemia patients are poorer in LMICs compared to HICs, primarily due to reduced access to quality healthcare.
This study aims to assess cancer treatment outcomes in LMICs, focusing on acute lymphoblastic leukemia/lymphoblastic lymphoma. The findings will inform future studies to implement evidence-based interventions that improve care quality and reduce treatment failures through targeted strategies.
The 2 groups in the trial
- All Cancer Diagnoses
Patients aged 0-21 years with any type of cancer diagnosis. Retrospective medical record review will capture incidence of treatment failure, including relapse, progression, or abandonment.
Treatment: Retrospective Medical Record Review
- Acute Lymphoblastic Leukemia / Lymphoblastic Lymphoma
Patients aged 0-21 years diagnosed with acute lymphoblastic leukemia or lymphoblastic lymphoma. Retrospective review will focus on therapy-related toxicities and treatment outcomes in this subgroup.
Treatment: Retrospective Medical Record Review
