Programme

Overview: Both the radiation modality and the way of dose delivery play a role in tissue response. The preclinical data demonstrated that FLASH delivery of the different types of radiation at ultra-high dose rates (>30-40 Gy/s) and conventional radiotherapy have similar anti-tumor responses; however, FLASH radiotherapy has less normal tissue toxicity. On the other hand, preclinical and clinical evidence suggests that particle therapy has more precise dose delivery and, therefore, may achieve a higher therapeutic efficacy than photon-based treatment. This debate session will argue whether FLASH radiotherapy is a more promising avenue for the future of radiation oncology than particle radiotherapy and discuss its immunomodulatory effects and limitations on the way to clinical translation.

Overview: The session will provide a concise overview on a role of radiotherapy in various haematological malignancies. It will start with the discussion on the role of Total Skin Electron Irradiation in patients suffering from non-T-cell lymphomas with extensive skin lesions (Prof. Blamek). This will be followed by the lectures describing a paradigm shift for target definition and dose prescription in radiotherapy of lymphomas with a particular focus on primary mediastinal B-cell lymphomas (Prof. Specht and Prof. Held). The session will end with a thought-provoking lecture featuring the interplay between radiation and CAR T-cell therapy in lymphoma management (Dr Niezink). After the lectures, time for audience discussion will be also provided.

Overview: In this session prestigious speakers will discuss and define current evidence for the optimal local radio-oncological treatment strategy with or without surgery for soft tissue sarcoma - the current evidence for EBRT, brachytherapy and IORT alone or for IORT /brachytherapy as a boost in adult soft-tissue sarcomas of the extremity, trunk and retroperitoneal space. For all treatment approaches the technical and practical state of the art considerations and recommendations will be also presented.

Overview: Proffered Papers are presented at one of the sessions scheduled in the main session halls. Each author will present orally for 7 minutes, followed by 3 minutes for discussion. Sessions will be streamed.

Overview: Mini-Orals are presented at one of the sessions scheduled in the two mini-oral theatres near the exhibition. Each author will present a 4-slide PowerPoint orally for 4 minutes, followed by 3 minutes for discussion. Sessions will not be streamed but authors are invited to upload per-recordings for the online platform.
