Phase II Study of Combination Chemotherapy for Newly Diagnosed Diffuse Anaplastic Wilms Tumors and Relapsed Favorable Histology Wilms Tumors in Patients Up to 30 Years Old

What this Trial Is About

Researchers are evaluating how well combination chemotherapy works in treating patients with newly diagnosed stages 2 to 4 diffuse anaplastic Wilms tumor DAWT and patients with relapsed favorable histology Wilms tumor FHWT. This phase II trial compares the effects of two chemotherapy regimens, UH-3 and ICECycloTopo, on event-free survival and overall survival, aiming to improve outcomes based on different relapse risk groups and prior treatments. The study also explores kidney toxicity, genetic markers, surgery impacts, and radiation therapy techniques to reduce side effects and better understand tumor behavior. Participants are assigned to one of two treatment groups. In Arm I Regimen UH-3, patients receive cycles of vincristine, doxorubicin, cyclophosphamide, carboplatin, etoposide, and irinotecan intravenously over various days in a 21-day cycle, with radiation therapy at week 7 of cycle 3 if needed. In Arm II Regimen ICECycloTopo, patients receive cycles of carboplatin, etoposide, ifosfamide, cyclophosphamide, and topotecan intravenously over 10 cycles every 21 days, with surgery andor radiation therapy during certain cycles as clinically indicated. Throughout the trial, patients undergo multiple imaging tests including CT scans, PET scans, chest x-rays, MRIs, abdominal ultrasounds, and bone scans, along with blood sample collections and biopsies. After completing treatment, follow-up visits occur every 3 months for the first 2 years, then every 6 months for years 3 and 4, and once at year 5. The main outcomes measured are event-free survival and overall survival up to 5 years from study entry, with ongoing monitoring for treatment effects and safety.
