Wilms Tumor and Other Childhood Kidney Tumors Treatment (PDQ®)–Health Professional Version

General Information About Childhood Kidney Tumors

Dramatic improvements in survival have been achieved for children and adolescents with cancer. Between 1975 and 2010, childhood cancer mortality decreased by more than 50%.[1] For children younger than 15 years with Wilms tumor, the 5-year survival rate has increased over the same time from 74% to 88%.[1] Childhood and adolescent cancer survivors require close monitoring because cancer therapy side effects may persist or develop months or years after treatment. (Refer to the PDQ summary on Late Effects of Treatment for Childhood Cancer for specific information about the incidence, type, and monitoring of late effects in childhood and adolescent cancer survivors.)

Childhood kidney cancers account for about 7% of all childhood cancers. Most childhood kidney cancers are Wilms tumor, but in the 15- to 19-year age group, most tumors are renal cell carcinoma. Wilms tumor can affect one kidney (unilateral) or both kidneys (bilateral). Less common types of childhood kidney tumors include rhabdoid tumors, clear cell sarcoma, congenital mesoblastic nephroma, Ewing sarcoma of the kidney, primary renal myoepithelial carcinoma, cystic partially differentiated nephroblastoma, multilocular cystic nephroma, primary renal synovial sarcoma, and anaplastic sarcoma. Nephroblastomatosisof the kidney is a type of nonmalignant neoplasia.[2,3]
