  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. Prognostic and predictive factors in laryngeal cancer treated with radiotherapy

    Author : Hedda Haugen; Göteborgs universitet; []
    Keywords : Laryngeal cancer; accelerated radiotherapy; predictive factors; pre-radiotherapy hemoglobin level; MVD; p53; Ki-67; EGFr; histopathologic differentiation.;

    Abstract : Radiotherapy (RT) and surgery are the only two curative treatments for patients with laryngeal cancer (LC). RT has the advantage that it offers a possibility to preserve a functioning larynx and hence a functioning normal voice. The response of tumors to RT is heterogeneous, even within the same tumor stage. READ MORE

  5. 3. Optimization of radiotherapy in locally advanced lung cancer

    Author : Andreas Hallqvist; Göteborgs universitet; []
    Keywords : radiotherapy; lung cancer;

    Abstract : Lung cancer is the leading cause of cancer death worldwide as well as in Sweden, where the incidence is around 3500 new cases per year. About 50% have distant metastases by the time of diagnosis and are treated with palliative intent. READ MORE

  6. 4. 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.

  7. 5. Epidermal Melanocyte Response to Radiotherapy

    Author : Per Fessé; Henrik Lindman; Ingela Turesson; Johan Ahlgren; Jan Nyman; Catharine West; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Melanocytes; fractionated radiotherapy; ΔNp63; MITF; PAX3; SOX10; p53; p21; BMI1; pRb; CXCR2; DNA-DSB; 53BP1; CXCR2;

    Abstract : Cutaneous interfollicular melanocytes protect the skin from UV-radiation (UVR), and their response to UVR is well established. To date, the response activated in melanocytes by repeated genotoxic insults from radiotherapy (RT) has not been explored. READ MORE
