Since its foundation in 1991, the SIOP Working Committee on Psychosocial Issues in Paediatric Oncology1 has developed and published 12 sets of Guidelines for health-care professionals treating children with cancer and their families. Those elements considered essential in the process of cure and care of children with cancer are summarized in this document as a formal statement, developed at the 2007 SIOP annual meeting in Mumbai. Elaboration of the concepts with detailed strategies for practice can be found in the referenced guidelines [1-12] and in a companion publication [13]. This article is a summary of what practitioners considered critical elements in the optimal care of the child with cancer, with the goal of stimulating a broader application of these elements throughout the SIOP membership.
