Child-centered communication in pediatric oncology can be challenging. We aimed to review communication interventions with children about cancer treatment and prognosis to identify potentially effective child-centered communication models and approaches. We updated a previous review on communication interventions in oncology and searched MEDLINE, Scopus, and PsychINFO for studies indexed between October 2019 up to October 2022. We further searched for ongoing studies on ClinicalTrials.gov. Communication interventions targeting pediatric oncology patients (below 18 years), with outcomes of communication, psychological symptoms or satisfaction in the target population were eligible. We identified 685 titles/abstracts, screened the full text of 34 studies and included only one published study and two ongoing studies. The published study tested a communication tool to help clinicians inform adolescents about treatment options and facilitate shared decision-making. No communication models were identified. We drew on knowledge from existing studies and guidelines to develop a new child-centered communication model.
