In about 10% of patients Wilms Tumor occurs in both kidneys, and in some instances one kidney has a malignant tumor while the other kidney has one or more benign nodules For Wilms tumors, survival is often measured using a 4-year survival rate. This refers to the percentage of children who live at least 4 years after their cancer is diagnosed. For example, a 4-year survival rate of 80% means that an estimated 80 out of 100 children who have that cancer are still alive 4 years after being diagnosed

  1. Wilms tumor arises from mesodermal precursors of the renal parenchyma (metanephros) and occasionally is found to arise in the extrarenal retroperitoneum, presumably within mesonephric remnants. At histologic analysis, Wilms tumor is composed of variable amounts of blastema, stroma, and epithelium (, Fig 1). The term teratoid Wilms tumor may be applied if there is differentiation along tissue lines not normally found in the kidney, such as bone, cartilage, and muscle

Wilms' tumor protein (WT1) has a role in transcriptional regulation and is expressed in the kidney and a subset of hematopoietic cells. Alteration of transcription factor function is a common mechanism in oncogenesis. The WT1 protein contains a DNA binding domain and any deletions or point mutations of the WT1 gene which destroy this activity. A tumor with changes in chromosome 1 is linked to worse outcomes after treatment. And, a tumor with changes in both of these chromosomes does not respond as well to standard treatment. Current research studies use more chemotherapy to treat children with a Wilms tumor that has these changes (see Types of Treatment)
