Can you survive 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 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.
How long can you live with Wilms tumor?

How many stages are there in Wilms tumor?
A staging system is a standard way for the cancer care team to sum up the extent of the tumor. In the United States, the Children’s Oncology Group staging system is used most often to describe the extent of spread of Wilms tumors. This system divides Wilms tumors into 5 stages using Roman numerals I through V.

Can Wilms tumor come back?
Wilms’ tumor relapse is not uncommon and accounts for approximately 15% of Wilms’ tumors with favorable histology . Most recurrent Wilms’ tumors have been reported to occur in the first 2 years after the primary diagnosis.
What is the main difference between neuroblastoma and Wilms tumor?
neuroblastoma may invade the kidney; whereas, a Wilms tumor may display exo- phytic growth, calcification, or large lymph node metastases or may cross the midline.
How does Wilms tumor affect the kidneys?
The urinary system — which includes the kidneys, ureters, bladder and urethra — is responsible for removing waste from the body through urine. Wilms’ tumor is the most common type of kidney cancer in children. Wilms’ tumor is a rare kidney cancer that primarily affects children.

What happens if a Wilms tumor ruptures?
Preoperative tumor rupture may result in tumor spillage, thus altering the prognosis. The overall cure rate of Wilms tumor in low risk children has risen to more than 90%. Yet, in cases of post-traumatic tumor rupture the rate drastically falls. Computed tomography of the abdomen may help to identify the complication.
