Follow-up Phase You/your child will be followed closely by our team of doctors and dieticians during the 90 days you/your child are on the study. Follow-up will occur when you are normally scheduled to see your doctor. This can occur at either the Pediatric Oncology outpatient clinics or when you are admitted to the BC Children's Hospital (Vancouver) or Stollery Children's Hospital (Edmonton). You do not have to make special appointments for the purpose of this study.
