Wilms' tumor (WT), also known as nephroblastoma, is a malignant embryonal kidney tumor composed of embryonic cells and is the most prevalent tumor among children, but isolated cases occur infrequently in the adult population. Adult WT is defined according to the criteria of Kilton, Matthews, and Cohen, which comprise age above 15 years and histological patterns characteristic of WT. We report a case of an adult WT with venous thrombus on an incomplete duplex collecting system.

Background: In the fifth National Wilms Tumor Study, patients received vincristine and dactinomycin (VA) without radiation for stage I focal anaplastic Wilms tumor (FAWT) and VA plus doxorubicin (DD4A) and radiation for stage II-IV FAWT. Four-year event-free survival (EFS) and overall survival (OS) for stage I FAWT were 67.5% and 88.

January 2025
Department of Urology, Mansoura Urology and Nephrology Center, Mansoura University, Mansoura, Egypt.
Purpose: To create a computer-aided prediction (CAP) system to predict Wilms tumor (WT) responsiveness to preoperative chemotherapy (PC) using pre-therapy contrast-enhanced computed tomography (CECT).
Materials And Methods: A single-center database was reviewed for children <18 years diagnosed with WT and received PC between 2001 and 2021. Patients were excluded if pre- and post-PC CECT were not retrievable.
Characterizing Sensitivity to Vincristine, Irinotecan, and Telomerase-targeted Therapy in Diffuse Anaplastic Wilms Tumor Patient-derived Xenografts.

Department of Surgery, St. Jude Children's Research Hospital, Memphis, Tennessee, USA. Electronic address:
Background: Patients with diffuse anaplastic Wilms tumor (DAWT) experience relatively poor oncologic outcomes. Previous work has described mechanisms of telomerase upregulation in DAWT, posing a potential therapeutic target.
Methods: We assessed in vitro sensitivity to vincristine, irinotecan, and telomerase-targeting drug 6-thio-2'-deoxyguanosine (6 dG) in DAWT cell lines WiT49 and PDM115 and in spheroids derived from cell lines and four DAWT patient-derived xenografts (PDX).
Impact of Hospital Volume on Survival for Pediatric Wilms Tumor.
Pediatr Blood Cancer
March 2025
Department of Surgery, Johns Hopkins University School of Medicine, Baltimore, Maryland, USA.
Background: Treatment for children with Wilms tumor (WT) is multidisciplinary, often including surgery, chemotherapy, and sometimes radiation therapy. High-volume hospitals (HVH) have been associated with improved outcomes in cancer care. Our study evaluates the association of hospital volume and survival outcomes in pediatric WT management.
