Clinical Trial Summary
This phase III trial studies using risk factors in determining treatment for children with
favorable tissue (histology) Wilms tumors (FHWT). Wilms Tumor is the most common type of
kidney cancer in children, and FHWT is the most common subtype. Previous large clinical
trials have established treatment plans that are likely to cure most children with FHWT,
however some children still have their cancer come back (called relapse) and not all survive.
Previous research has identified features of FHWT that are associated with higher or lower
risks of relapse. The term "risk" refers to the chance of the cancer coming back after
treatment. Using results of tumor histology tests, biology tests, and response to therapy may
be able to improve treatment for children with FHWT.
Description:
PRIMARY OBJECTIVES:
I. To maintain event-free survival (EFS) for Stage I favorable histology Wilms tumor (FHWT)
patients without adverse biology who are also (1) 2 to < 4 years of age, OR (2) age < 2 years
with tumor weight of 550 grams or more, OR (3) age 4+ years with epithelial histology subtype
while reducing post-nephrectomy therapy from vincristine, actinomycin (EE-4A) to Nephrectomy
Only. (Stage I Nephrectomy Only Stratum 2) II. To improve EFS for Stage I FHWT patients with
age < 2 years AND nephrectomy weight < 550g AND whose tumors have adverse biology by treating
with EE-4A instead of Nephrectomy Only. (Stage I EE-4A Stratum 3) III. To evaluate whether
addition of vincristine and irinotecan to standard EE-4A (novel vincristine, actinomycin,
irinotecan [Regimen VIVA]) is non-inferior to vincristine, actinomycin, doxorubicin (DD-4A)
in terms of EFS among Stage II FHWT patients whose tumors demonstrate adverse biology. (Stage
II: VIVA versus [vs] DD-4A Randomization) IV. To evaluate whether omission of doxorubicin
(EE-4A) is non-inferior to historical DD-4A in Stage III FHWT patients with standard biology
or post-therapy blastemal predominance. (Stage III: EE-4A) V. To demonstrate the
non-inferiority of vincristine, actinomycin, doxorubicin, cyclophosphamide, etoposide and
irinotecan (Regimen MVI) to vincristine, dactinomycin, doxorubicin, cyclophosphamide and
etoposide (Regimen M) in the treatment of Stage III FHWT patients whose tumors exhibit
adverse biology (post-chemotherapy blastemal predominance excluded). (Stage III: Regimen MVI
vs Regimen M Randomization) VI. To demonstrate the non-inferiority of Regimen MVI to Regimen
M in the treatment of Stage IV FHWT patients with adverse biology, slow incomplete lung
response (SIR), or extrapulmonary metastases (EPM) (post-therapy blastemal predominance
excluded). (Stage IV: Regimen MVI vs Regimen M Randomization) VII. To demonstrate the
superiority of vincristine, doxorubicin, cyclophosphamide, etoposide, carboplatin and
irinotecan (Regimen UH-3) vs historical DD-4A or Regimen M in treatment of Stage III or IV
FHWT patients with blastemal predominance at delayed nephrectomy. (Stage III-IV: UH-3
(Blastemal Predominance)
SECONDARY OBJECTIVES:
I. To describe outcomes for Stage I FHWT patients without adverse biology who are either less

EXPLORATORY OBJECTIVES:
I. To determine the impact of imaging schedule and modality (chest x-ray [CXR], ultrasound
[US], versus computed tomography/magnetic resonance imaging [CT/MRI], versus clinical
symptoms) on relapse, timing of detection of relapse, burden of disease at relapse (as
assessed by retrospective central imaging review), as well as impact on survival.
II. To analyze the impact of radiologically determined pulmonary tumor burden on outcomes.
III. To assess whether imaging modality (ultrasound, CT, MRI with or without hepatocyte
specific contrast agent) at diagnosis is associated with detection of increased number of
liver metastases, and whether modality choice impacts surgery and/or radiation planning for
liver metastases.
IV. To accurately describe the responses of extrapulmonary metastases to the various
therapeutic modalities (chemotherapy, radiation therapy, and surgery) through central review
of institutional imaging at various stages of treatment, and to correlate institutionally
interpreted radiologic response interpretations with central review.
V. To describe the association of the number of anatomically relevant and pathologically
confirmed lymph nodes sampled and percent of positive lymph nodes (LNs) on EFS and overall
survival [OS].
VI. To document the surgical and/or medical rationale and approach for biopsy (including type
of biopsy, number of biopsies, and site of biopsy) for all patients who are treated with the
approach of initial biopsy and delayed nephrectomy.
VII. To describe sites of recurrence for patients with liver metastases according to the
surgery and/or radiation therapy administered for residual liver lesions at Week 6 and 12.
VIII. To increase the number of patients eligible to avoid lung radiation therapy (RT) by
encouraging resection of residual pulmonary nodules for patients defined as Stage IV FHWT
with standard biology and who have 1-3 residual pulmonary nodules on imaging after Cycle 2,
by omitting lung RT for those who are found to have no viable tumor in resected nodules.
IX. To describe whether residual lung lesions at end of therapy are associated with relapse.
X. To improve the reliability of data derived from central surgical review through the
implementation of a standardized operative note.
XI. To describe the treatment, perioperative morbidity and outcome of patients noted to have
inferior vena cava (IVC) tumor thrombus at time of diagnosis, including surgical approach,
pathology findings and specific radiation therapy received.
XII. To determine the feasibility of employing intensity modulated radiation therapy (IMRT)
with central quality assurance (QA) monitoring within the prescribed time frame.
XIII. To determine the lung tumor and liver tumor control rate using intensity modulated
radiation therapy (IMRT) and/or proton therapy and compare it to standard 3-dimensional
radiotherapy in the current study and the AREN0533 study.
XIV. To determine the flank and abdominal tumor control rates in children with Stage IV FHWT
who received abdominal radiotherapy after 2 cycles of chemotherapy in this study (delayed
abdominal radiation) and compare it to AREN0533 study where abdominal radiotherapy was
performed within 2 weeks of nephrectomy (upfront abdominal radiation).
XV. To compare abdominal relapse according to protocol-recommended radiotherapy fields (flank
vs. whole abdominal) in the current study and compare it to the abdominal relapse according
to radiotherapy fields (flank vs. whole abdominal) in the AREN0532 and AREN0533 studies.
XVI. To determine the impact of radiotherapy on local and distant control rates for EPM sites
and compare them to EPM sites not receiving radiation.
XVII. To describe the rate and severity of recurrent hepatotoxicity in patients who undergo
re-introduction of chemotherapy after experiencing hepatopathy.
XVIII. To collect serial blood and urine samples to bank for future research studies.
