OBJECTIVE: Central nervous system (CNS) complications can be seen in patients with leukemia, depending on the disease itself and the chemotherapeutic agents used. This study focused on CNS complications during treatment in children with acute leukemia in a single pediatric institution.
METHODS: CNS complications were evaluated retrospectively in 115 patients with ALL and AML. Patients with CNS leukemia infiltration at the time of diagnosis or during a neurological event, late-onset encephalopathy, peripheral neuropathy, or a previous history of neurological abnormalities were excluded from the study.
RESULTS: A total of 115 children's clinical records with acute leukemia over a four-year period were reviewed. Acute CNS complications developed in 23.1% of acute myeloid leukemia (AML) patients and in 13.5% of acute lymphoblastic leukemia (ALL) patients. CNS complications developed most frequently during the induction phase of the treatment (66.7%). Seizures were the most common symptom (9 patients, 50%), followed by hemiparesis (4 patients, 22.2%) and headache (4 patients, 22.2%). Six patients (33.3%) had chemotherapy-induced toxic leukoencephalopathy, two (11.1%) had Wernicke's encephalopathy, and one patient (5.6%) each had sinus vein thrombosis, posterior reversible encephalopathy syndrome, and CNS infection. Sequelae occurred in three patients (16.7%), and only one patient (5.6%) died due to a CNS complication.
CONCLUSION: A wide variety of symptoms can be observed in childhood leukemia, depending on the disease itself, the chemotherapeutic agents used and a lot of other conditions such as nutritional problems. Our research shows that several CNS complications might manifest with similar symptoms; differentiated diagnosis between the underlying etiological reasons can be made by neuroimaging.
