Presentation acuity, induction mortality, and resource utilization in infants with acute leukemia

Area of Science:

• Pediatric Oncology
• Hematology
• Clinical Research

Background:

• Infant acute leukemia treatment presents unique challenges, with higher induction mortality rates observed in infants compared to older children.
• Limited data exists on the specific presentation characteristics and supportive care needs of infants diagnosed with leukemia.

Purpose of the Study:

• To compare presentation acuity, induction mortality, and resource utilization in infants versus noninfants (<10 years) diagnosed with acute lymphocytic leukemia (ALL) and acute myeloid leukemia (AML).

Main Methods:

• Retrospective analysis of pediatric hospital data from the Pediatric Health Information System.
• Comparison of presentation acuity, induction mortality, and supportive care resource utilization between infant and noninfant groups for ALL and AML.

Main Results:

• Infants were more likely to present with multisystem organ failure for both ALL and AML.
• Infants with ALL exhibited higher induction mortality than noninfants, with similar rates to children with AML.
• Infants with both ALL and AML required greater supportive care, including blood products, diuretics, oxygen, and ventilation.

Conclusions:

• Infants with leukemia present with more severe illness and higher acuity.
• Induction mortality and supportive care needs for infants with ALL mirror those of children with AML, and are significantly higher than for noninfant ALL patients.
