Summary
This study is looking at how well certain combinations of chemotherapy work for children and young people with Wilms tumours that are either:
- Newly diagnosed stage II-IV diffuse anaplastic Wilms tumours (DAWT), or
- Favourable histology Wilms tumours (FHWT) that have come back after treatment (relapsed).
The chemotherapy combinations being tested include several medicines that attack cancer cells in different ways. Some kill cancer cells directly, while others stop the cells from growing, dividing or spreading.
Two main treatment groups are being studied:
- UH-3 regimen - for patients with newly diagnosed DAWT or standard-risk relapsed FHWT (those who previously received only two chemotherapy drugs).
- ICE/Cyclo/Topo regimen - for patients with high-risk or very high-risk relapsed FHWT (those who previously received three or more chemotherapy drugs).
Patients may also receive radiation therapy or surgery, if it is medically appropriate.
The goal of the trial is to understand how these chemotherapy combinations affect patients - both the benefits and any side effects - and to help doctors determine the best treatments for different groups of children with Wilms tumours.
