Advanced MR Imaging acquisition and analysis for assessment of toxicity after radiation therapy in primary brain tumors

Summary of the Project

The aim of this project is to investigate the effect of photon- versus proton-beam radiation therapy for primary brain tumor patients on tumor tissue and surrounding brain tissue using advanced Magnetic Resonance Imaging (MRI) methods. The ultimate goal is to establish a rationale for proton beam therapy in primary brain tumor patients with a long-term life-expectancy at risk of developing radiation sequelae.

After establishment of an advanced MRI protocol, all primary brain tumor patients treated with photon-/proton-(chemo)radiotherapy at the University Hospital Carl Gustav Carus Dresden will prospectively be imaged pre-(chemo)radiotherapy and at three-monthly intervals thereafter. MR changes will be qualitatively and quantitatively assessed and correlated with the irradiated volumes as well as neurocognitive function and quality of life of the patients. Using a “radiomics” approach, signatures predicting local control and acute/late toxicity after (chemo)radiotherapy will be developed.

Scientific Goals

  • Predict neurocognitive function and quality of life in primary brain tumor patients undergoing photon- or proton-beam (chemo)radiotherapy.
  • Identify intracranial sub-volumes linked to increased risk of neurocognitive side-effects, and
  • evaluate adequate dose delivery while avoiding these radiation-sensitive sub-volumes in the future.
  • Sustain neurocognitive function and quality of life by employing optimal beam quality and radiation dose distribution.
