The<unk>  <unk>  is a worldwide clinical trial cooperative<unk>  supported by the National Cancer Institute (NCI) and fashioned with the mission of studying childhood cancers. It was formed in 2000 with the merging of four independent cooperative<unk> s; the<unk> 's Cancer Study<unk>  (CCG), Pediatric<unk><unk>  (POG), Intergroup Rhabdomyosarcoma Study<unk>  (IRS), and the National Wilms Tumor Study<unk>  (NWTS). This merger has seen its fair share of problems, especially with regard to integrating the various databases associated with each individual cooperative<unk> . One such initiative to consolidate these databases involves caBIG or the cancer Biomedical Informatics Grid, which is guided and supported by the NCI in Bethesda, Maryland.
