Similarities and controversies in imaging of pediatric renal tumors: A SIOP‐RTSG and COG collaboration

alexandrossfakianakis shared this article with you from Inoreader Similarities and controversies in imaging of pediatric renal tumors: A SIOP‐RTSG and COG collaboration via Pediatric Blood & Cancer Abstract Malignant renal tumors are rare in children, and Wilms tumors (WTs) are the most common subtype. Imaging plays an essential role in the diagnosis, staging, and follow-up of these patients. Initial workup for staging is mainly performed by cross-sectional imaging modalities such as computed tomography (CT) and magnetic resonance imaging (MRI). Imaging approach within the two core international groups, the Children's Oncology Group (COG, North America) and the International Society of Pediatric Oncology - Renal Tumor Study Group (SIOP-RTSG, Europe), differs. Whereas abdominal ultrasound (US) is used for the initial diagnosis of a suspected pediatric renal tumor globally, COG protocols support the use of CT or MRI for locoregional staging, contrary to the preference for MRI over CT for abdominopelvic evaluation within the SIOP-RTSG. The purpose of this manuscript is to summarize current imaging approaches, highlighting differences and similarities within these core international grou ps, while focusing on future innovative efforts and collaboration within the HARMONICA initiative.
