- Brief Summary
This phase II trial studies how well combination chemotherapy works in treating patients with newly diagnosed stage II-IV diffuse anaplastic Wilms tumors (DAWT) or favorable histology Wilms tumors (FHWT) that have come back (relapsed). Drugs used in chemotherapy regimens such as UH-3 (vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan) and ICE/Cyclo/Topo (ifosfamide, carboplatin, etoposide, cyclophosphamide, and topotecan) work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. This trial may help doctors find out what effects, good and/or bad, regimen UH-3 has on patients with newly diagnosed DAWT and standard risk relapsed FHWT (those treated with only 2 drugs for the initial WT) and regimen ICE/Cyclo/Topo has on patients with high and very high risk relapsed FHWT (those treated with 3 or more drugs for the initial WT).
- Detailed Description
PRIMARY OBJECTIVES:
I. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/ carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the event-free survival (EFS) of patients with newly diagnosed stage 4 diffuse anaplastic Wilms tumor (DAWT) as compared to historical controls.
II. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the EFS of patients with standard-risk relapsed favorable histology Wilms tumor (SRrFHWT) as compared to historical controls.
SECONDARY OBJECTIVES:
I. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the overall survival (OS) of patients with newly diagnosed stage 4 DAWT as compared to historical controls.
II. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the OS of patients with SRrFHWT as compared to historical controls.
III. To evaluate whether the addition of vincristine/irinotecan to cyclophosphamide/carboplatin/etoposide alternating with vincristine/doxorubicin/cyclophosphamide improves the EFS and OS of patients with newly diagnosed stage 2 and 3 DAWT as compared to historical controls.
IV. To establish EFS and OS for high-risk (HRrFHWT) and very high risk (VHRrFHWT) relapsed favorable histology Wilms tumor treated with ifosfamide/carboplatin/etoposide alternating with cyclophosphamide/ topotecan.
EXPLORATORY OBJECTIVES:
I. To describe renal toxicity of ifosfamide/carboplatin/etoposide in HRrFHWT and VHRrFHWT patients using conventional and novel biomarkers of renal toxicity (urine NGAL, cystatin C and Kim1) in the context of the chemotherapy regimens used on this study.
II. To collect and bank serial blood and urine samples in patients with newly diagnosed DAWT or relapsed FHWT and tumor tissue in patients with relapsed FHWT, for future analysis.
III. To assess the impact of p53 gene and protein expression on outcome for patients with newly diagnosed DAWT.
IV. To determine EFS/OS in the subsets of patients with newly diagnosed DAWT or relapsed FWHT who undergo gross total resection at all disease sites at diagnosis or after neoadjuvant chemotherapy.
V. To describe the rate of regional lymph node sampling at the time of nephrectomy with the use of a pre-operative surgical checklist for patients with newly diagnosed DAWT.
VI. To determine the feasibility of intensity modulated radiation therapy (IMRT) with central quality assurance (QA) monitoring to reduce radiation induced toxicity to the heart, thyroid, breast and solitary kidney for children with lung and liver metastases (part of an overarching aim in this study and across frontline favorable histology Wilms tumor studies).
VII. To validate that circulating tumor-derived deoxyribonucleic acid (ctDNA) can identify high-risk genomic features, define prognostic risk groups, and identify patterns of tumor evolution associated with the development of treatment resistance.
