Abstract

Background: Patients with cancer treated with the pro-drug ifosfamide may experience drug-induced neurotoxicity. Ifosfamide-induced neurotoxicity (IIN) is well described in the adult literature, but there is limited knowledge about this toxicity in pediatrics, especially in children with solid tumors. Methods: In this retrospective descriptive study, the author reviewed 7 years of clinical data regarding patients with solid tumors who received ifosfamide at a large, urban pediatric medical center. The author used descriptive statistics and logistic regression to describe the incidence of IIN and identify demographic and clinical factors most likely to be associated with the toxicity. Results: In a sample of 169 pediatric patients who received ifosfamide between 2011 and 2018, 13% developed symptoms of IIN. The author identified ifosfamide doses >2,000 mg/m2 to be a risk factor for IIN in the study sample (OR 17.82; 95 CI [2.17, 146.18]; p = .0073) and cited other variables as possible risk factors, though each could be linked to participants' ifosfamide exposure. Discussion: This study is the largest to describe IIN specifically in the pediatric solid tumor population. The study findings suggest the pattern of toxicity observed in adult patients should not be assumed in children. The author identified one risk factor that may predispose children to develop IIN and recommends further attention be paid to this toxicity in the pediatric population.
