Methods
The study was approved by the institutional review and ethics boards at
the University of Utah. We queried the electronic database from the
Associated Regional and University Pathologists (ARUP) Laboratories for
all cases of “bone marrow necrosis”, “acute lymphoblastic leukemia”,
“acute myeloid leukemia” and “neuroblastoma” in patients that were
18 years and younger from January 1st, 2010 to
February 1st, 2020. ARUP Laboratory is an enterprise
of the University of Utah and its Department of Pathology. It serves as
a not-for-profit national reference laboratory.
The clinical, laboratory and radiological information of the patients
were obtained from electronic medical records.
