Abstract

Currently, there is no cure for pediatric diffuse brain stem (BS) tumors. Radiotherapy, including proton therapy, is an important component of combination treatment for this cancer, especially in children with a complicated medical history. The article addresses the issues of therapy for pediatric BS tumors and reports the use of proton re-irradiation in a 9-year-old boy with unverified diffuse BS tumor. Proton re-irradiation is an effective treatment option that can sustain and improve the quality of life and prolong survival in children with diffuse BS tumors.

  • Optimized intensity-modulated proton therapy [17] for the metabolically active recurrent lesion was delivered to the patient at the Federal Research and Clinical Center for Medical Radiology and Oncology from January 26, 2021 to March 5, 2021

  • As more evidence is being accumulated about the safety of this approach for treating pediatric CNS tumors, re-irradiation is being increasingly used to manage recurrent/progressive Diffuse intrinsic pontine glioma (DIPG) in children [28,29,30]
