Can Wilms tumor be cured?

About 85 to 90% of Wilms tumor patients with favorable histology can be cured. Histology is the way cells look under the microscope—in this case tumor cells. Cure rates for patients with anaplastic histology, a more aggressive form of Wilms tumor, are lower.

What is the survival rate of Wilms tumor?

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.

Can adults get Wilms tumor?
