The Food and Drug Administration (FDA) received reports of malignancies in children using tumor necrosis factor (TNF) blockers, raising concerns of an associated risk and prompting an investigation. Researchers from the FDA set out to identify all reports of malignancy in children using infliximab, etanercept, and adalimumab and their report is published in the August issue of Arthritis & Rheumatism, a journal of the American College of Rheumatology.
