Is this trial a fit for you?

Likely a good fit

Ideal candidates are children aged 30 years or younger with newly diagnosed stages II-IV diffuse anaplastic Wilms tumors or relapsed favorable histology Wilms tumors.

Probably not a fit

Patients with Wilms tumors that are not in the specified stages or those older than 30 years may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This phase II trial evaluates the effectiveness of combination chemotherapy regimens in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) and relapsed favorable histology Wilms tumors (FHWT). The study compares the outcomes of two chemotherapy regimens: UH-3 and ICE/Cyclo/Topo, assessing their impact on event-free survival (EFS) and overall survival (OS). Patients will receive treatments that include various chemotherapy agents aimed at halting tumor growth and improving survival rates. The trial aims to provide insights into the efficacy of these regimens compared to historical controls.

Why it matters

Potential benefit: If successful, this study could improve survival rates for children with aggressive forms of Wilms tumors.

How similar studies have gone: Other studies have shown promise with combination chemotherapy approaches in treating Wilms tumors, suggesting potential for success in this trial.

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Patients with newly diagnosed stages 2 - 4 diffuse anaplastic Wilms tumor must be enrolled on APEC14B1, consented to Part A - Eligibility Screening, and have received an initial stratum assignment showing DAWT (if anaplasia first identified at diagnostic, pre-treatment nephrectomy or biopsy) or a final stratum assignment showing DAWT (if anaplasia first noted at delayed nephrectomy) prior to enrollment on AREN1921. Prior enrollment on APEC14B1 is not an eligibility requirement for patients with relapsed favorable histology Wilms tumor.
* Patients must be =\< 30 years old at study enrollment
* Patients with the following diagnoses are eligible for this study:

  * Newly diagnosed stages 2 - 4 diffuse anaplastic Wilms tumor as confirmed by central review
  * Favorable histology Wilms tumor at first relapse. Relapsed FHWT patients must have previously achieved remission for their initial FHWT diagnosis to be eligible for this study. The relapse risk groups are defined as follows, regardless of radiation therapy:

    * Standard-Risk relapse: Patients who received two chemotherapy agents for frontline therapy; primarily actinomycin D and vincristine
    * High-Risk relapse: Patients who received three chemotherapy agents for frontline therapy; primarily vincristine, actinomycin D and doxorubicin or vincristine, actinomycin D and irinotecan
    * Very High-Risk relapse: Patients who received four or more chemotherapy agents as part of initial therapy; primarily regimen M or its variations
* Patients with newly diagnosed DAWT must have had histologic verification of the malignancy. For relapsed FHWT patients, biopsy to prove recurrence is encouraged, but not required

  * Note: For relapsed FHWT patients, an institutional pathology report confirming favorable histology Wilms tumor (from relapse, if available, or from original diagnosis) must be available for upload prior to initiation of protocol therapy
* Patients with newly diagnosed Stages 2 - 4 diffuse anaplastic Wilms tumor must be enrolled on AREN1921 within 2 weeks of the tumor-directed surgery or biopsy procedure that first confirms a diagnosis of DAWT, whether at initial diagnostic procedure or delayed nephrectomy (such surgery/biopsy is day 0). For patients who received prior therapy for presumed favorable histology Wilms tumor, later confirmed to have diffuse anaplastic Wilms tumor at subsequent review of the initial biopsy
* Patients with newly diagnosed DAWT who undergo upfront nephrectomy must have at least 1 lymph node sampled prior to study enrollment
* Patients must have a performance status corresponding to Eastern Cooperative Oncology Group (ECOG) scores of 0, 1 or 2. Use Karnofsky for patients \> 16 years of age and Lansky for patients =\< 16 years of age
* Patients must have a life expectancy of \>= 8 weeks
* Diffuse Anaplastic Wilms Tumor: Patients with diffuse anaplastic histology must have had no prior systemic therapy, except in the following situations:

  * Patients with diffuse anaplastic Wilms tumor who received no more than 12 weeks of pre nephrectomy chemotherapy for what was originally presumed to be favorable histology Wilms tumor, subsequently confirmed to be diffuse anaplastic Wilms tumor at delayed nephrectomy
  * Patients with diffuse anaplastic Wilms tumor who received no more than 6 weeks of chemotherapy following upfront biopsy, initiated within 14 days of biopsy, for presumed favorable histology Wilms tumor based on institutional review, but subsequently corrected to diffuse anaplastic Wilms tumor based on the initial stratum assignment on APEC14B1-REN
  * Treatment consisting of vincristine/doxorubicin/cyclophosphamide initiated on an emergent basis and within allowed timing as described
  * Note: Patients who received prior therapy for presumed favorable histology Wilms tumor, later identified to have diffuse anaplastic Wilms tumor as per above, must begin study treatment starting at cycle 3 (week 7) of regimen UH 3. Patients who received emergency radiation to preserve organ function are eligible as noted. Patients who received radiation as part of standard of care for presumed newly diagnosed favorable histology Wilms tumor, along with chemotherapy as noted above, prior to identification of diffuse anaplasia, are also eligible
* Relapsed Favorable Histology Wilms Tumor: Patients must not have received prior chemotherapy for their relapsed favorable histology Wilms tumor diagnosis. In addition, patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study

  * Myelosuppressive chemotherapy: Must not have received within 2 weeks of entry onto this study
  * Radiation therapy (RT): \>= 2 weeks (wks) must have elapsed for local palliative RT (small port); \>= 6 months must have elapsed if prior craniospinal RT or if \>= 50% radiation of pelvis; \>= 6 wks must have elapsed if other substantial bone marrow (BM) radiation. Patients with relapsed favorable histology Wilms tumor who received emergency radiation to preserve organ function are eligible and do not need to washout with the above criteria
* Patients may not be receiving any other investigational agents (within 4 weeks prior to study enrollment)
* Peripheral absolute neutrophil count (ANC) \>= 750/uL (performed within 7 days prior to enrollment)
