PRIMARY OBJECTIVES:
I. To utilize clinical and biological characteristics of acute leukemias to screen for patient eligibility for available phase I/II Pediatric Acute Leukemia (PedAL) sub-trials.
II. To maintain a longitudinal and comprehensive registry from relapse in children and young adults with recurrent and refractory leukemia.
OUTLINE:
Patients undergo collection of blood and/or bone marrow samples at baseline, end of treatment cycle(s), and at relapse/refractory disease status (if applicable).
After completion of study, patients are followed up every 3 months for 2 years, and then every 6 months for 3 years.
Inclusion Criteria:
- Patients must be less than 22 years of age at the time of study enrollment
- Patient must have one of the following:
- Patient has known or suspected relapsed/refractory (including primary refractory)
AML
- This includes isolated myeloid sarcoma
- Patient has known or suspected relapsed/refractory (including primary refractory)
myeloid leukemia of Down syndrome
- Patient has known or suspected relapsed ALL that meets one of the following
criteria:
- Second or greater B-ALL medullary relapse, excluding KMT2Ar.
- Any first or greater B-ALL medullary relapse involving KMT2Ar.
- Any first or greater T-ALL medullary relapse with or without KMT2Ar.
- Patient has known or suspected relapsed/refractory (including primary refractory)
mixed phenotype acute leukemia (MPAL)
- Patient has known or suspected de novo or relapsed/refractory (including primary
refractory) treatment-related AML (t-AML) or treatment-related myelodysplastic
syndrome (t-MDS)
- Patient has known or suspected de novo or relapsed/refractory (including primary
refractory) myelodysplastic syndrome (MDS)
- Patient has known or suspected de novo or relapsed/refractory (including primary
refractory) juvenile myelomonocytic leukemia (JMML)
