Guidelines developed by the American Association for Cancer Research Childhood Cancer Predisposition Workshop (AACR-CCPW) include full abdominal ultrasound (USS) every 3 months from diagnosis until the 4th birthday, renal ultrasound every 3 months from age 4–7 years, and AFP screening every 3 months until the 4th birthday for all patients with BWSp (81). Here, AFP is linked to cancer.
