- Event-free survival (EFS) [ Time Frame: From study entry to the earliest of relapse or disease progression, second malignant neoplasm, or death from any cause, assessed up to 5 years after study enrollment ]For Strata 1-3, the primary analysis of EFS will consist of a one-sample, one-sided log rank test versus a historical control cohort (or representative distribution) with stratum-specific type I error levels. For Stratum 4, the primary analysis of EFS is descriptive, but with a desired level of precision to estimate 4-year EFS at the time of the final analysis (2 years after the last patient enrolls).
- Overall survival (OS) [ Time Frame: From study entry to death due to any cause, assessed up to 5 years after study enrollment ]For each stratum, OS will be estimated at the same time as the conclusive (interim or final) analysis and reported descriptively with 95% pointwise confidence bands.
- Incidence of grade 3-5 renal toxicity [ Time Frame: Up to 30 weeks on average for Stratum 4 only ]Incidence of grade 3-5 renal toxicity during protocol therapy will be monitored for Stratum 4 as part of a prospective safety monitoring plan. At the time of final study analysis, renal toxicity will be described by factors including age, relapse risk group, and timing and association (descriptive) with the exploratory renal toxicity biomarkers.
- Collection of blood and urine samples [ Time Frame: Up to 42 weeks on average for Strata 1-3 and up to 30 weeks on average for Stratum 4 ]For all Strata 1-4, serial blood and urine samples will be collected (during protocol therapy, at the end of protocol therapy, and at first relapse) and banked for future analysis such as evaluation of minimal residual disease by assessing levels of circulating tumor-derived deoxyribonucleic acid.
- p53 biomarker analysis [ Time Frame: Based on tissue collected at diagnosis (Strata 1 and 2 only), with outcomes collected up to 5 years after study entry ]For patients with diffuse anaplastic Wilms tumors (DAWT) (Strata 1 and 2), p53 from diagnostic tissue will be assessed, and rates of p53 mutations described overall and within each stratum. Degree of anaplasia as a predictor of p53 mutation status will be analyzed in logistic regression models, and association of p53 status with EFS and OS will be analyzed in Cox regression models, stratified by disease stage. Possible interactions between p53 mutation status and degree of anaplasia in outcome models will be explored.
- EFS for patients with gross total disease resection [ Time Frame: From study entry to the earliest of relapse or disease progression, second malignant neoplasm, or death from any cause, assessed up to 5 years after study enrollment ]EFS will be described for newly diagnosed disease stage 2-4 DAWT patients (Strata 1 and 2) and relapsed favorable histology Wilms tumors (FHWT) patients (Strata 3 and 4) who have gross total disease resection prior to enrollment or at the time of delayed nephrectomy following adjuvant chemotherapy. Kaplan-Meier curves will be reported by strata with 95% confidence bands. Potential prognostic factors for these patients will be explored in Cox regression models.
- OS for patients with gross total disease resection [ Time Frame: From study entry to death due to any cause, assessed up to 5 years after study entry ]OS will be described for newly diagnosed disease stage 2-4 DAWT patients (Strata 1 and 2) and relapsed FHWT patients (Strata 3 and 4) who have gross total disease resection prior to enrollment or at the time of delayed nephrectomy following adjuvant chemotherapy. Kaplan-Meier curves will be reported by strata with 95% confidence bands. Potential prognostic factors for these patients will be explored in Cox regression models.
- Association of the number of nodes examined with EFS and OS [ Time Frame: Nodal information from upfront or delayed nephrectomy, with outcomes collected for up to 5 years after study entry ]The number of lymph nodes examined at the time of primary nephrectomy and number of positive nodes will be collected for all DAWT patients who enroll to Strata 1 or 2. The association of the number of nodes examined with EFS and OS will be explored in Cox regression models stratified by disease stage. For each of these analyses, association will be expressed either as a single hazard ratio if the effect is found to be linear, or as continuous functions on the hazard ratio scale if the effect is found to be non-linear. Similar models will be fit to examine the association between ratio of positive nodes to nodes examined and outcomes. Confidence intervals or bands will be reported for all quantities.

Inclusion Criteria:
- Patients with newly diagnosed stages 2 - 4 diffuse anaplastic Wilms tumor must be enrolled on AREN03B2 and have received an initial risk assignment showing DAWT (if anaplasia first identified at diagnostic, pre-treatment nephrectomy or biopsy) or a delayed nephrectomy classification showing DAWT (if anaplasia first noted at delayed nephrectomy) prior to enrollment on AREN1921. Prior enrollment on AREN03B2 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
