Wilms Tumour Treatment at RGCIRC, Delhi
Overview
Wilms tumour, also known as nephroblastoma, is one of the most common kidney cancers in children and is highly treatable when diagnosed early. Although the condition can be frightening for families, most children respond very well to treatment, and survival rates are among the highest in paediatric oncology. At Rajiv Gandhi Cancer Institute & Research Centre (RGCIRC), children with Wilms tumour receive specialised care supported by experienced paediatric oncology teams, advanced diagnostics, and treatment plans tailored to their stage and tumour biology. With an emphasis on safety, precision, and long-term wellbeing, RGCIRC offers comprehensive, evidence-based care for children diagnosed with Wilms tumour.
What is Wilms Tumour (Nephroblastoma)?
Wilms tumour is a childhood kidney cancer that develops when immature kidney cells grow uncontrollably and form a mass within one or both kidneys. It most commonly affects children under the age of five, although older children may occasionally be diagnosed. While the exact cause is often unknown, the tumour arises from early kidney cells that did not mature properly during foetal development. Because Wilms tumour can grow without causing immediate discomfort, many families first notice it as a painless swelling in the abdomen. At Rajiv Gandhi Cancer Institute & Research Centre (RGCIRC), specialists use advanced paediatric imaging and diagnostic tools to accurately identify the tumour, assess its spread, and plan safe, effective treatment tailored to each child’s needs.
Types of Wilms Tumour
Wilms tumour can present in different forms, and identifying the specific type helps guide treatment decisions and predict outcomes. At Rajiv Gandhi Cancer Institute & Research Centre (RGCIRC), specialists carefully evaluate the tumour’s characteristics, including how the cells look under a microscope and whether one or both kidneys are affected. The various types of Wilms tumour are:
Unilateral Wilms Tumour
This is the most common form, where the tumour affects only one kidney. Most children fall into this category and respond well to standard treatment approaches.
Bilateral Wilms Tumour
In this form, both kidneys are involved at the time of diagnosis. Treatment requires a careful balance between removing cancer and preserving kidney function, often using chemotherapy to shrink tumours before surgery.
Favourable Histology
Most Wilms tumours have favourable histology, meaning the cancer cells appear less aggressive. These cases have excellent treatment outcomes, with high cure rates.
Unfavourable (Anaplastic) Histology
This type is less common but more aggressive. The cells have abnormal features that may require more intensive treatment. Early identification is important to guide therapy.
Syndromic Wilms Tumour
Some children develop Wilms tumour as part of a genetic syndrome associated with congenital anomalies or developmental disorders. These cases often need specialised evaluation and long-term monitoring.
Causes of Wilms Tumour
- Genetic mutations: Changes in specific genes involved in kidney development may predispose a child to Wilms tumour.
- Abnormal kidney development: Some children are born with kidney tissue that did not mature properly in the womb.
- Inherited conditions: Although uncommon, certain genetic syndromes, including WAGR syndrome and Beckwith–Wiedemann syndrome, can increase the risk.
- Family history: Having a close relative with Wilms tumour slightly increases the chance of developing the condition.
- Prenatal or environmental influences (rare): Factors affecting kidney formation during pregnancy may contribute in a small number of cases.
Signs and Symptoms of Wilms Tumour
- Abdominal swelling or a noticeable lump, often found by a parent or caregiver
- Belly pain or discomfort, which may come and go
- Fever without an obvious cause
- Nausea or vomiting, particularly if the tumour affects nearby organs
- Constipation or changes in bowel habits
- Blood in the urine, which may appear pink, red, or brown
- High blood pressure, caused by hormone-like substances produced by the tumour
- Fatigue, weakness, or reduced activity levels
- Loss of appetite or feeling full quickly
- Unexplained weight loss in some children
How is Wilms Tumour Diagnosed?
Accurate diagnosis is an essential first step in planning safe and effective treatment for Wilms tumour. At Rajiv Gandhi Cancer Institute & Research Centre (RGCIRC), specialists use child-friendly imaging, laboratory tests, and clinical evaluations to understand the tumour’s size, spread, and impact on kidney function. The following diagnostic tools help create a complete and reliable assessment.
Physical Examination
Doctors begin with a gentle abdominal examination to check for swelling, tenderness, or a palpable mass.
Ultrasound of the Abdomen
Ultrasound is often the first imaging test used in children, as it is safe, painless, and highly effective for identifying kidney abnormalities. It helps confirm the presence of a mass within the kidney and provides clear information about the tumour’s size, location, and relationship to surrounding structures. This initial scan forms an important part of the diagnostic process for Wilms tumour at RGCIRC.
CT Scan or MRI
- MRI is especially useful for small children due to its detailed soft-tissue imaging.
- CT may be used when further anatomical clarity is needed.
Chest X-ray or CT Scan
Because Wilms tumour can spread to the lungs, imaging of the chest helps assess whether any metastasis is present.
Blood Tests and Kidney Function Tests
These tests evaluate overall health, anaemia, kidney performance, and readiness for surgery or chemotherapy.
Urine Tests
Urine analysis helps assess kidney function and detect bleeding or infection.
Biopsy (In Select Cases)
A biopsy is not always needed. It may be performed when:
- The diagnosis is unclear
- The tumour appears atypical
- Bilateral disease requires kidney-sparing planning
By combining these investigations, RGCIRC’s paediatric oncology team gains an accurate understanding of the tumour and develops a treatment plan that prioritises safety, cure, and long-term kidney function.
Stages of Wilms Tumour
Staging describes how far Wilms tumour has spread and helps determine the most appropriate treatment approach. At Rajiv Gandhi Cancer Institute & Research Centre (RGCIRC), staging is assessed using imaging studies, surgical findings, and pathology reports. Understanding the stage not only guides therapy but also provides important information about prognosis. The following stages reflect the commonly used classification for Wilms tumour.
Stage I
The tumour is confined to one kidney and can be completely removed with surgery. Children with Stage I disease typically have an excellent prognosis.
Stage II
The tumour has spread beyond the kidney into surrounding tissues but is still fully removable with surgery. Treatment may involve chemotherapy after surgery to prevent recurrence.
Stage III
Cancer has spread to nearby lymph nodes, major blood vessels, or other structures within the abdomen. Additional treatments, including radiation therapy and chemotherapy, are often required.
Stage IV
Cancer has spread to distant organs such as the lungs, liver, bones, or brain. Treatment typically involves systemic therapy, along with surgery and radiation when appropriate.
Stage V
Both kidneys are affected at the time of diagnosis. This stage requires specialised, kidney-preserving strategies and careful coordination between surgery and chemotherapy.
Staging provides a roadmap for treatment planning at RGCIRC, helping the team deliver the most effective therapy while protecting long-term kidney function and overall health.
Treatment Options for Wilms Tumour at RGCIRC
Treatment for Wilms tumour is highly effective, especially when started early. Most children recover fully with the right combination of therapy. At Rajiv Gandhi Cancer Institute & Research Centre (RGCIRC), each child’s treatment plan is based on the tumour’s stage, histology, and whether one or both kidneys are affected. The goal is always to cure the disease while preserving as much kidney function as possible. The following treatment approaches form the foundation of modern Wilms tumour care.
Surgical Treatment Options
Surgery is a key component of Wilms tumour treatment and is often the first major step once the tumour has been fully evaluated. Depending on the tumour’s size, location, and whether one or both kidneys are involved, several surgical approaches may be used to ensure effective treatment while preserving as much kidney function as possible. The main surgical options include:
- Radical nephrectomy: Complete removal of the affected kidney when the tumour is confined to one side.
- Partial nephrectomy (kidney-sparing surgery): Performed when only part of the kidney is affected or when preserving kidney tissue is crucial, such as in bilateral disease.
- Bilateral kidney-preserving procedures: Used for tumours in both kidneys, aiming to remove as much tumour tissue as possible while protecting healthy areas.
- Minimally invasive paediatric surgery: Selected cases may benefit from laparoscopic techniques that reduce postoperative pain and support faster recovery.
Chemotherapy
Chemotherapy is one of the most important treatments for Wilms tumour and may be given before or after surgery. It may be used to:
- Shrink the tumour before surgery
- Treat remaining cancer cells after surgery
- Manage advanced or metastatic disease
- Prepare both kidneys for safe, organ-preserving surgery in bilateral cases
Radiation Therapy
Radiation is used only when indicated, typically in more advanced stages or when tumour cells are found outside the kidney.
It may help to:
- Treat abdominal disease not fully removable by surgery
- Manage spread to lymph nodes or nearby tissues
- Treat metastasis, especially in the lungs, when required
Targeted Therapies (For Resistant Tumours)
Some tumours with specific genetic changes may respond better to targeted medicines that act on cancer-specific pathways. These therapies are used in selected cases where standard treatment needs enhancement.
Risk-Adapted and Individualised Treatment
Modern Wilms tumour care focuses on tailoring treatment intensity to each child’s specific needs. This personalised approach helps achieve high cure rates while minimising the long-term effects of therapy. The following guidelines help tailor care for every child:
- Low-risk tumours are treated with milder therapy to limit side effects while still ensuring excellent outcomes.
- High-risk tumours need stronger treatment, which may include a combination of chemotherapy, surgery, and radiation to fully control the disease.
By adjusting treatment intensity to each child’s needs, RGCIRC helps protect long-term health while giving every child the best chance of cure.

Frequently Asked Questions (FAQs)
What causes Wilms tumour in children?
Most Wilms tumours develop due to changes in early kidney cell development, and in many cases the exact cause is not known. Some children may have genetic syndromes or congenital anomalies that increase the risk, but many have no identifiable risk factors.
How is Wilms tumour diagnosed?
Diagnosis typically involves an abdominal ultrasound, CT or MRI scans, blood and urine tests, and, in select cases, a biopsy. These tests help determine the tumour’s size, spread, and impact on kidney function.
Is Wilms tumour curable?
Yes. Wilms tumour is one of the most treatable childhood cancers, and survival rates are very high when treatment is started early. Most children respond well to a combination of surgery and chemotherapy, with radiation used only when necessary.
Does every child with Wilms tumour need radiation therapy?
No. Radiation is recommended only in specific situations, such as advanced stages or when tumour cells are found outside the kidney. Many children are successfully treated with surgery and chemotherapy alone.
What is recovery like after Wilms tumour surgery?
Recovery varies depending on the type of surgery performed. Children who undergo radical nephrectomy or kidney-sparing surgery typically recover well with proper pain management, nutritional support, and follow-up care.
How often does Wilms tumour come back after treatment?
Recurrence is uncommon, especially in children with favourable-histology tumours. Regular follow-up visits and imaging studies help detect any recurrence early and ensure long-term health.
Can Wilms tumour affect both kidneys?
Yes. In some cases, Wilms tumour is present in both kidneys at diagnosis, called bilateral Wilms tumour. Specialised treatment is used to shrink tumours first so that as much kidney tissue as possible can be preserved during surgery.
