While 80% of these are Wilms tumors (or nephroblastomas), other kidney tumors of childhood include renal cell carcinoma (~4%), clear cell sarcoma of the kidney (~3%), congenital mesoblastic nephroma (~2%), rhabdoid tumor of the kidney (~2%), and cystic nephroma (~2%). Wilms tumor (WT) is the second most common extracranial solid tumor in pediatrics, following neuroblastoma. While overall survival in patients with WT has increased to 90% due to advances in medical and surgical treatment, there remain subsets of patients who do not have favorable outcomes. Moreover, patients with renal cell carcinoma, clear cell carcinoma, and rhabdoid tumor of the kidney have considerably worse outcomes compared to WT. This chapter will focus primarily on WT as the most prevalent pediatric kidney tumor.
