Advanced Services Available at Comer Children's Hospital

Comer Children’s offers comprehensive diagnosis and treatment for Wilms tumor. As one of the busiest pediatric cancer programs in the Midwest, we have the expertise and resources to care for children with any type of Wilms tumor.

Diagnosing Wilm's Tumor

The most important initial test used to diagnose Wilms tumor is a CT scan. The scan reveals the location of the tumor in one or both kidneys and shows the extent of the disease. This begins the staging process to determine if the tumor has spread to other parts of the abdomen or to the lungs.

In most cases, the affected kidney must be removed. A pathologist examines a microscopic sample of the kidney tissue to verify the diagnosis and to determine the aggressiveness and invasiveness of the tumor.

Wilm's Tumor Treatment at Comer Children's Hospital

Each patient is assigned a stage based on the results of the CT scan, the pathology and other tests. Wilms tumor treatment is always treated with a combination of surgery and chemotherapy and, in some cases, radiation therapy.

Some children will be eligible to participate in COG clinical trials. These treatment protocols are part of a nationwide, National Cancer Institute-sponsored effort to evaluate and monitor newer therapies.

Genetic Counseling for Wilm's Tumor

In cases where there is a suspicion of a genetic link, Wilms tumor patients may be referred to our Pediatric Familial Cancer Clinic. This highly specialized clinic is dedicated to helping children and their families with inherited cancers.

Support services for Patients

Children facing cancer often have ongoing medical, emotional, social and developmental needs. Our doctors, nurses, social workers and child life specialists recognize these issues and can provide your family with the resources and tools to keep you informed, find assistance and help you cope.

Wilm's Tumor Long-Term Care

While the cure rate for Wilms tumor is more than 90 percent, these patients may face other health issues as they grow older. Comer Children's Childhood Cancer Survivors Center is an integrated program aimed at the prevention and treatment of long-term issues associated with cancer therapy.
