Abstract The SickKids Cancer Sequencing (KiCS) Program, launched in 2016, evaluates the clinical utility of paired tumor/germline Next-Generation Sequencing (NGS) in pediatric oncology patients with hard-to-cure and rare cancers. In anticipation of further widespread adoption of NGS, we aimed to characterize the experiences and perspectives of adolescents and parents of patients who have already undergone NGS evaluation, focusing on the psychosocial impact and personal utility.
