About this study
The standard treatment for acute lymphoblastic leukemia (ALL), lymphoblastic lymphoma (LLy, a type of non-Hodgkin lymphoma), and mixed phenotype acute leukemia/lymphoma (MPAL) is chemotherapy. The treatment usually uses 4–7 chemotherapy drugs during the first part of treatment.
This study will collect the blood, bone marrow, and tissue samples we need to properly diagnose and classify a child’s leukemia or lymphoma. We will study genetic changes in these samples and do other tests. The treatment is risk-based. This means that a child’s treatment will be based on several leukemia- or lymphoma-specific features that can affect how well they respond to treatment.
The main goal of this study is to find out whether a child’s leukemia or lymphoma is low-risk, standard-risk, or high-risk. The term “risk” refers to the chance of the cancer coming back during or after treatment. The child’s risk category will determine the treatment they will receive.
