Feasibility of Screening for Early Late Effects of Contemporary Therapy in High-Risk Neuroblastoma Survivors

Primary outcomes

1. Feasibility will be measured by at least 66% participation rate

   Time frame: Up to 24 months after participant enrollment.

   To determine the feasibility of conducting comprehensive evaluations, leveraging the established SJLIFE (St. Jude Lifetime Cohort Study) study infrastructure, in survivors of HR-NBL (high-risk neuroblastoma) who are greater than 2 years from completion of contemporary therapy and were previously treated at SJCRH (St. Jude Children's Research Hospital). To establish the feasibility, we will estimate the participation rate. The study is considered to have an acceptable participation rate if the 95% lower bound of the participation rate exceeds 66%. Participation is defined as completing ≥ 75% of all proposed assessments.

2. To describe the health outcomes of survivors of HR-NBL previously treated at SJCRH with contemporary era therapy who are greater than 2 years from completion of therapy.

   Time frame: Health outcomes will be assessed on Days 1, 2, 3, 4, or 5 during the SJLIFE and LEGACY campus visit.

   Participants will go through a comprehensive assessment including the SJLIFE core battery and additional studies in the categories of neurological and autonomic, immunological, quality of life, hematological, renal and metabolic, endocrine, cardiorespiratory, and gastrointestinal (see table below). Their health conditions will be defined by normative data and will be graded using the Revised Common Terminology Criteria for Adverse Events (CTCAE) used by Hudson et al. in SJLIFE studies. The prevalence, cumulative incidence, and latency of selected treatment complications in survivors will be estimated.

   Resting/minimum/maximum heart rate, nerve velocities (median, deep peroneal, common peroneal, Sural), sweat total/baseline/end offset volumes, complete blood cou

3. Socioeconomic status will be measured by self-reported demographic information

   Time frame: Socioeconomic status, assessed via the household survey, will be assessed on Days 1, 2, 3, 4, or 5 during the LEGACY and SJLIFE campus visit.

   Answers to the household survey, which includes single-item evaluations of self-reported race, ethnicity and primary language, collected per U.S. Health and Human Services guidelines, health literacy utilizing a validated 1-item screen, educational attainment, household materials hardship (HMH), and household income.
