Session

Overview: Re-irradiation is a promising treatment for a large number of patients with otherwise limited therapeutic options. In recent years, our understanding of the relationship between the dose of radiation, the volume of tissue being irradiated, and the potential for late effects has improved significantly. Still, the tolerance of normal tissue to re-irradiation is not well understood. Furthermore, high level prospective evidence on re-irradiation is lacking, especially with regards to safety, optimal selection of eligible patients and treatment modality. This session aims to explore data on (1) constraints, (2) possible advanced technical approaches as well as employing (3) EBRT and (4) brachytherapy for re-irradiation.
