Understanding the principles in management of Wilms' tumour: can imaging assist in patient selection?

Author information

Department of Radiodiagnosis, Tata Memorial Centre, Mumbai, India.


The management of Wilms' tumour has evolved through thorough systematic research, predominantly lead by two groups: the Wilms' Tumour Study Committee of the International Society of Paediatric Oncology (SIOP) and National Wilms' Tumor Study Group (NWTSG) of North America. These two groups differ in their approach: SIOP advocates initial chemotherapy of 4-6 weeks followed by surgery, whereas the NWTSG advocates upfront surgery, with certain exceptions. This review briefly discusses the principles, and pros and cons of each approach. Both the treatment approaches have equivalent outcomes (in the form of event-free survival and overall survival), when compared stage-wise. With this knowledge, modern imaging can be used for individualizing treatment in anticipation of minimizing complications. The review identifies critical imaging features and discusses the reliability of imaging based on current reports in the literature.
