Learn About Wilms Tumor

What is the definition of Wilms Tumor?

Wilms tumor (WT) is a type of kidney cancer that occurs in children.

What are the alternative names for Wilms Tumor?

Nephroblastoma; Kidney tumor - Wilms

What are the causes of Wilms Tumor?

WT is the most common form of childhood kidney cancer. The exact cause of this tumor is unknown in most children.

A missing iris of the eye (aniridia) is a birth defect that is sometimes associated with WT. Other birth defects linked to this type of kidney cancer include certain urinary tract problems and enlargement of one side of the body, a condition called hemihypertrophy.

It is more common among some siblings and twins, which suggests a possible genetic cause.

The disease occurs most often in children about 3 years old. More than 90% of cases are diagnosed before 10 years of age. In rare cases, it is seen in children older than 15 years of age, and in adults.

What are the symptoms of Wilms Tumor?

Symptoms may include any of the following:

  • Abdominal pain
  • Abnormal urine color
  • Constipation
  • Fever
  • General discomfort or uneasiness (malaise)
  • High blood pressure
  • Increased growth on only one side of the body
  • Loss of appetite
  • Nausea and vomiting
  • Swelling in the abdomen (abdominal hernia or mass)
  • Sweating (at night)
  • Blood in urine (hematuria)

What are the current treatments for Wilms Tumor?

If your child is diagnosed with WT, do not prod or push on the child's belly area. Use care during bathing and handling to avoid injury to the tumor site.

The first step in treatment is to stage the tumor. Staging helps the provider determine how far the cancer has spread and to plan for the best treatment. Surgery to remove the tumor is planned as soon as possible. Surrounding tissues and organs may also need to be removed if the tumor has spread.

Radiation therapy and chemotherapy will often be started after surgery, depending on the stage of the tumor.

Chemotherapy given before the surgery is also effective in preventing complications.

What is the outlook (prognosis) for Wilms Tumor?

Children whose tumor has not spread have a 90% cure rate with appropriate treatment. Prognosis is also better in children younger than 2 years of age.

What are the possible complications of Wilms Tumor?

The tumor may become quite large, but usually remains self-enclosed. The spread of the tumor to the lungs, lymph nodes, liver, bone, or brain is the most worrisome complication.

High blood pressure and kidney damage may occur as the result of the tumor or its treatment.

Removal of WT from both kidneys may affect kidney function.

Other possible complications of the long-term treatment of WT may include:

  • Heart failure
  • Secondary cancer elsewhere in the body that develops after the treatment of first cancer
  • Short height
When should I contact a medical professional for Wilms Tumor?

Contact your child's provider if:

  • You discover a lump in your child's abdomen, blood in the urine, or other symptoms of WT.
  • Your child is being treated for this condition and symptoms get worse or new symptoms develop, mainly cough, chest pain, weight loss, or persistent fevers.
How do I prevent Wilms Tumor?

For children with a known high risk for WT, screening using ultrasound of the kidneys or prenatal genetic analysis may be suggested.

This research study uses special immune system cells called AGAR T cells, a new experimental treatment. The body has different ways of fighting infection and disease. No single way seems perfect for fighting cancers. This research study combines two d...
