  1. 1. Radiation therapy of upper gastrointestinal cancers with scanned proton beams : A treatment planning study

    Författare :Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Treatment planning; gastric cancer; liver metastases; photon beam therapy; proton beam therapy; dosimetric comparison; normal tissue complication probability; risk of radiation-induced secondary cancer; patient selection; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Proton beam therapy (PBT), using scanned beams, is an emerging modality used for the treatment of cancer. The clinical advantages of PBT, compared to commonly used photon beam therapy, have been demonstrated in different studies. LÄS MER

  3. 2. Beyond Survival - Cognition after Pediatric Brain Tumor

    Författare :Ingrid Tonning Olsson; Lund Pediatrik; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Pediatric Brain Tumor; Cognition; Late sequelae; Cranial Radiation Therapy; Neuropsychology;

    Sammanfattning : Background: Pediatric Brain Tumor (PBT) survivors suffer from cognitive sequelae, especially within the areas of cognitive tempo, attention, executive function and memory. The cognitive difficulties are often accentuated over the years, but knowledge about the long term trajectory is still scarce. LÄS MER

  4. 3. Comparative study of Radiation Therapy of Targets in the Upper Abdomen with Photon- or Scanned Proton-beams

    Författare :Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; photon radiotherapy; proton beam radiotherapy; gastric cancer; liver metastases; Medical Radiation Physics; medicinsk strålningsfysik;

    Sammanfattning : Recently, there has been an increase in the number of proton beam therapy (PBT) centers operating worldwide. For certain cases, proton beams have been shown to provide dosimetric and radiobiological advantages when used for cancer treatment, compared to the regular photon-beam based treatments. LÄS MER

  5. 4. Regional differences in the response of neural stem cells and their microenvironment to ionizing radiation

    Författare :Nina Hellström; Göteborgs universitet; []
    Nyckelord :ionizing radiation; neurogenesis; neural stem cells; inflammation; microglia; stem cell niche; trophic support;

    Sammanfattning : Radiation therapy is one of the most effective tools for treating malignant tumors; however, cranial irradiation often results in intellectual impairment and cognitive deficits, such as impaired learning and memory. Ionizing radiation generates DNA damage, causing proliferative cells to undergo apoptosis. LÄS MER

  7. 5. Characterizing and modulating the effects of ionizing radiation to the juvenile hippocampus

    Författare :Malin Blomstrand; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low-dose radiation; CNS; hippocampus; apoptosis; cytokines; growth factors; microglia; medulloblastoma; hippocampal sparing; tumor bed boost; cognitive risk estimation;

    Sammanfattning : Survival rates after childhood cancer treatment have improved, leading to a growing population of survivors. Radiotherapy is an important tool for curing cancer in the brain. Unfortunately, radiotherapy is associated with late side effects e.g. LÄS MER
