Wilms Tumor Prognosis

The 5-year survival rate for children with a Wilms tumor is 93%. However, the rate varies according to the stage of the disease. Stage I, II, and III tumors with a favorable histology have a 4-year survival rate that ranges from 95% to 100%. The histology of a tumor is how its cells look under a microscope.
