A rapidly developing tumor of the kidney that usually occurs in children. It is the most common renal tumor of childhood. It is associated with chromosomal deletions, esp. from chromosomes 11 and 16. In the past, the mortality from this type of cancer was extremely high; however, newer approaches to therapy have been very effective in controlling the tumor in about 90% of patients.
