• Patients newly diagnosed with T-lymphoblastic (T-cell) or B-lymphoblastic precursor (BCP) leukaemia (ALL) according to the WHO-classification of Tumours of Haematopoietic and Lymphoid Tissues (Revised 4th edition 2017) and with a diagnosis confirmed by an accredited laboratory at a participating paediatric oncology or adult haematology centre
• Age 0 - < 46 years (one day before 46th birthday) at the time of diagnosis, with the exception of infants with KMT2A-r BCP ALL (see exclusion criteria below)
• Patients with surface immunoglobulin negative (sIG-) BCP-ALL and an IG::MYC rearrangement, unless they have a concurrent BCL2/6 rearrangement. T-ALL patients with MYC translocations
• Informed consent signed by the patient and/or parents/legal guardians according to country-specific age related guidelines
• The ALL diagnosis should be confirmed by an accredited laboratory at a participating paediatric oncology or adult haematology centre
• The patient should be diagnosed and treated at a participating paediatric oncology or adult haematology centre in the participating countries
• The patient should be a resident in one of the participating countries on a permanent basis or should intend to settle in a participating country, for instance by an application for asylum. Patients who are visiting the country as tourists should not be included. However, returning expatriots and patients who intend to stay at least for the duration of the treatment with primary diagnosis abroad may be included if no treatment has been administered and the diagnostic procedures are repeated at a participating centre

• Patients with mature B-ALL (as defined by surface IG positivity) or any patients with IG::MYC and a concurrent BCL2/6 rearrangement
• Previously known ALL prone syndromes (e.g. Li-Fraumeni syndrome, germline ETV6 mutation), except for Down syndrome. Exploration for such ALL prone syndromes is not mandatory and patients in whom genetic work-up reveals a new germ-line mutation (index-cases) will remain in the study
• Treatment with systemic corticosteroids corresponding to (>10mg prednisolone/m2/day) for more than one week and/or other chemotherapeutic agents in a 4-week interval prior to diagnosis (pre-treatment)

• Age >45 years at diagnosis
• Relapse of ALL
• Patients with Ph-positive ALL (documented presence of t(9;22)(q34;q11) and/or of the BCR::ABL1 fusion transcript). These patients will be transferred to an appropriate trial for t(9;22) if available
