Whole Abdominal Irradiation Treatment in Pediatric Patients with Wilms Tumor

Abstract

Wilms tumor is the most frequent primary malignant renal neoplasm in pediatric patients. Despite high survival rates—approaching 90%—achieved through multidisciplinary treatment strategies, minimizing long-term toxicity remains essential. This study reports on the implementation of Whole Abdominal Irradiation (WAI) in the treatment of pediatric Wilms tumor, focusing on a clinical case of a 5-year-old male diagnosed with stage IIIc intermediate-risk Wilms tumor of the right kidney, complicated by tumor rupture.

Radiotherapy planning integrated advanced techniques such as cVMAT and immobilization using the VAC-LOC system to optimize dose distribution and spare organs at risk, particularly the remaining kidney. The therapeutic approach emphasized non-anesthetized treatment sessions, made possible by the radiologic technologist’s ability to establish trust and rapport with the patient. Outcomes were favorable, and the treatment was completed without complications.

This experience underscores the pivotal role of radiologic technologists in pediatric oncology. Their technical expertise, combined with interpersonal competence, not only enhances therapeutic precision but also contributes meaningfully to patient compliance and overall care quality in young patients undergoing complex radiotherapy.
