Patient Navigation for Improving Transition Success Among Multiply Disadvantaged Young Adult Survivors of Childhood Cancer

The goal of this clinical trial is to improve the successful healthcare transition from pediatric to adult-focused care for childhood cancer survivors. The main questions it aims to answer are * Receipt of the intervention (vs. standard of care control) will increase the proportion of CCS achieving transition success to adult-focused survivorship care from 50% to 70%. * Receipt of the intervention (vs. standard of care control) will significantly reduce patients' unmet HRSN. * Intervention effectiveness will be moderated by sociodemographic factors (gender, race/ethnicity, insurance status), medical risk for late effects, HRSN burden, and patient-reported outcomes (quality of life, self-efficacy). Researchers will compare those that receive intervention versus standard of care. Patients are randomized to either an intervention group, receiving structured PN-led sessions and tailored support for care transitions, or a control group receiving standard follow-up by a nurse case manager. High-HRSN patients in the intervention arm get monthly check-ins and coordinated handoffs to adult care providers for continuity.

Inclusion Criteria: * diagnosed between the ages of 0-19 years with cancer or with any condition treated with cancer-like therapy. * currently in follow up at survivorship clinic or had a survivorship launch visit during the 12 months prior to study activation. * current age 20-29 (\>95% of patients will be age 20-21) * meet LIFE Clinic transition readiness criteria, as clinically applied: * at least 5 years off treatment * medically stable * demonstrate a workable understanding of transition * have an identified primary care provider * able to speak and read English or Spanish * can provide informed consent. Exclusion Criteria: * do not meet transition criteria * speak a language other than English or Spanish * are significantly impaired and cannot provide informed consent.
