3D Conformal Radiotherapy for Nephroblastoma: Unusual Techniquein Dalal Jamm Hospital

Abstract

Nephroblastoma, or Wilms tumor, is the most common kidney tumor in children, most commonly occurring between one and five years of age with a peak incidence around three and a half years. Multidisciplinary treatment (chemotherapy-surgeryradiotherapy) allows an overall survival of 90% at 10 years (1). Intensity-modulated radiation therapy (IMRT) either with a particle
accelerator or with helical tomotherapy can deliver an optimal dose of radiation while preserving healthy developing organs in this subject (2). This irradiation technique was not available in ourpractice setting. We report the case of a nephroblastoma treated by a three-dimensional conformational radiotherapy (RC3D) technique with respect to the dose constraints decreed by the IMRT.
