Local Control of Bladder/Prostate Rhabdomyosarcoma: An Expert Consensus Guideline From the International Soft Tissue Sarcoma Consortium (INSTRuCT)

The local treatment of bladder and prostate rhabdomyosarcoma is a multidisciplinary decision, incorporating elements of patient age, tumor size and location, nodal involvement, and access to local expertise and technology. The relative absence of long-term bladder and bowel function outcome data complicates discussions, particularly given improved survival rates and development of new surgical and radiotherapy techniques. These INSTRuCT guidelines, a collaboration of the Children's Oncology Group, Soft Tissue Sarcoma Committee, European Pediatric Soft Tissue Sarcoma Study Group, and the Cooperative Weichteilsarkom Studiengruppe, reflect international expert consensus and are intended to inform practice, generate discussion, and highlight areas of future inquiry.
