  2. 1. Radiotherapy for head and neck cancer : costs and benefits of time, dose and volume

    Author : Karin Söderström; Björn Zackrisson; Werner Dubrowsky; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; head and neck cancer; adjuvant treatment; accelerated fractionation; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Abstract : Background In the treatment of head and neck cancers (HNCs), radiotherapy (RT) has the advantage of organ preservation compared to surgery. However, treatment toxicities associated with RT can affect important functions for everyday life, both in the acute and late stage. READ MORE

  4. 2. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

    Author : Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Abstract : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. READ MORE

  5. 3. Heavy-ion transport codes for radiotherapy and radioprotection in space

    Author : Davide Mancusi; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; charge-changing cross sections; transport codes; radiotherapy; Monte-Carlo codes; heavy ions; radioprotection in space;

    Abstract : Simulation of the transport of heavy ions in matter is a field of nuclear science that has recently received attention in view of its importance for some relevant applications. Accelerated heavy ions can, for example, be used to treat cancers (heavy-ion radiotherapy) and show some superior qualities with respect to more conventional treatment systems, like photons (x-rays) or protons.

  6. 4. Radiotherapy in a FLASH : Towards clinical translation of ultra-high dose rate electron therapy

    Author : Elise Konradsson; Lund Medicinsk strålningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; Dosimetry; Ultra-high dose rate; Electron therapy; FLASH; Fysicumarkivet A:2023:Konradsson;

    Abstract : FLASH radiotherapy (FLASH-RT) is a promising new approach to radiotherapy that has the potential to transform the field. By administering radiation at ultra-high dose rates (UHDR) on a millisecond timescale, FLASH-RT may increase normal tissue tolerance compared to conventional radiotherapy while maintaining the anti-tumoral effect.

  7. 5. Patient Outcomes after Radiotherapy of Prostate Cancer. Impact of Absorbed Dose and Treated Volume

    Author : Elisabeth Rasmusson; LUCC: Lunds universitets cancercentrum; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer diagnosis; radiotherapy; brachytherapy; external beam; Dose- response; side effects; erectile dysfunction; lymphedema; hip osteoarthritis; Fractionation;

    Abstract : Abstract Backgound Prostate cancer is the most common form of cancer in men in Sweden. Radiotherapy, including external beam radiation therapy (EBRT) and brachytherapy (BT), is important treatment alternatives to surgery and active surveillance. READ MORE
