Overview
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, as well as a specimen bank, from relapse in children and young adults with acute leukemias.
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.
