Cognitive Intervention at the End of Therapy for Survivors of Childhood ALL Treated on TOTXVI

Computer-based cognitive training has been found to be helpful for improving attention and working memory in pediatric and adult patients with existing cognitive difficulties. A previous study was conducted at St. Jude Children's Research Hospital with survivors of childhood cancer who were experiencing difficulties with attention and/or working memory. Findings from that study indicated that the use of Cogmed, computer-based cognitive training, is effective in improving attention and working memory in survivors. Researchers want to learn whether Cogmed intervention completed at the end of therapy for acute lymphoblastic leukemia will be effective for all survivors (i.e., regardless of whether they have existing difficulties). PRIMARY OBJECTIVES: To evaluate the overall participation rate in a randomized, standard-of-care controlled trial of computerized cognitive intervention administered at the end of TOTXVI therapy. To estimate the study completion rate in a randomized, standard-of-care controlled trial of computerized cognitive intervention administered at the end of TOTXVI therapy. To estimate the compliance rate for participants randomized to the intervention arm of a computerized cognitive intervention administered at the end of TOTXVI therapy. To estimate the standard deviation for the overall cohort on a measure of working memory. To use neuroimaging data collected in the context of the Total Therapy XVI trial to explore candidate biomarkers predictive of response to the computerized cognitive intervention.

Transcranial Direct Current Stimulation of the Temporal Cortex in Survivors of Childhood Acute Lymphoblastic Leukemia (ALL)

Brief Overview: Children and adolescents diagnosed with cancer will experience problems with learning, memory and attention during and after completing their cancer therapy. There are many factors that contribute to this problem, but investigators have recently identified that chemotherapy agents used in treating Acute Lymphoblastic Leukemia (ALL) may disrupt normal brain development. A novel device has been developed that may help correct this disruption. Direct Current Stimulation (DCS) uses a very low level of constant electrical current to stimulate specific parts of the brain. It has been used in patients with stroke to great benefit. Our study at St. Jude Children's Research Hospital is designed to see if this technique will benefit survivors of childhood cancer. Specifically, investigators wish to see if stimulating one part of the brain gives a greater benefit than stimulating another part of the brain. Primary Objective Evaluate the feasibility of conducting repeated on-site Transcranial Direct Current Stimulation (tDCS) in children who are long-term survivors of Secondary Objectives To estimate the potential efficacy for powering a future larger study using tDCS to improve cognitive performance in children by suppressing over connected neural hubs in long-term survivors of childhood ALL. To compare the performance of anodal stimulation of the frontal lobe to cathodal suppression of the superior temporal lobe on cognitive performance.
