Treatment Options

 

Treatment for Wilms tumor usually involves a combination of pediatric oncology therapies designed to eliminate childhood kidney cancer while protecting long-term health, growth, and development. The specific treatment plan for pediatric kidney cancer depends on factors such as the stage of the Wilms tumor, tumor histology, whether the disease has spread beyond the kidney, and the child’s overall health and treatment response.

 

Surgery (Nephrectomy)

 

Surgery for Wilms tumor is one of the most important parts of treatment for childhood kidney cancer. The goal of nephrectomy surgery is to safely remove the tumor while preserving as much healthy kidney tissue as possible.

​

Types of Surgery for Wilms Tumor:

​

• Radical nephrectomy involving removal of the entire affected kidney

• Partial nephrectomy used in selected cases to preserve kidney function

• Bilateral kidney-sparing surgery for children with tumors affecting both kidneys

 

During pediatric kidney cancer surgery, nearby lymph nodes may also be examined to determine whether the cancer has spread beyond the kidney.

 

Chemotherapy for Wilms Tumor

​

Chemotherapy for Wilms tumor uses specialized anti-cancer medications to destroy childhood kidney cancer cells, shrink tumors, and reduce the risk of relapse after treatment. Chemotherapy is commonly used before or after nephrectomy surgery depending on the stage and characteristics of the pediatric kidney cancer.

​

Chemotherapy May:

​

• Shrink tumors before surgery

• Destroy remaining cancer cells after nephrectomy

• Treat metastatic Wilms tumor that has spread beyond the kidney

• Reduce the risk of recurrent childhood kidney cancer

 

Common chemotherapy drugs used for Wilms tumor may include vincristine, dactinomycin, doxorubicin, cyclophosphamide, etoposide, carboplatin, and ifosfamide.

​

Radiation Therapy for Wilms Tumor

​

Radiation therapy for Wilms tumor uses carefully targeted high-energy treatment to destroy remaining childhood kidney cancer cells and reduce the risk of recurrence. Radiation therapy is most often used in higher-stage disease, metastatic pediatric kidney cancer, lung metastases, or recurrent Wilms tumor.

​

Radiation Therapy May:

​

• Target areas where cancer cells remain after surgery

• Treat metastatic disease involving the lungs or abdomen

• Be combined with chemotherapy and surgery

• Reduce the risk of recurrent Wilms tumor

 

Pediatric radiation oncology teams carefully plan treatment to minimize exposure to healthy tissues and reduce long-term side effects whenever possible.

​

Stem Cell Transplant for Relapsed Wilms Tumor

​

Some children with recurrent or treatment-resistant Wilms tumor may require high-dose chemotherapy followed by autologous stem cell transplant. Stem cell transplant is generally reserved for relapsed pediatric kidney cancer or higher-risk disease that requires more intensive treatment.

 

Stem Cell Transplant May Help:

​

• Allow higher-dose chemotherapy treatment

• Restore bone marrow function after intensive therapy

• Improve long-term survival chances in selected cases

 

Recovery after pediatric stem cell transplant often requires prolonged hospitalization, immune system recovery, infection monitoring, and long-term survivorship follow-up care.

​

Long-Term Survivorship and Follow-Up Care

​

After treatment for Wilms tumor ends, many children continue pediatric oncology follow-up care for several years. Long-term survivorship monitoring helps assess recovery, identify possible late effects of treatment, and monitor for recurrent childhood kidney cancer.

​

Survivorship Monitoring May Include:

​

• Imaging surveillance and follow-up scans

• Kidney function monitoring

• Cardiac and pulmonary assessment

• Growth and developmental evaluations

• Fertility counseling

• Emotional and psychological support

 

Advances in pediatric oncology, supportive care, and survivorship medicine continue to improve long-term outcomes and quality of life for children treated for Wilms tumor.
