  2. 21. Radiation burden from modern radiation therapy techniques including proton therapy for breast cancer treatment - clinical implications

    Author : Anna M. Flejmer; Alexandru Dasu; Gunnar Adell; Olle Stål; Margaretha Stenmarker; Thomas Björk-Eriksson; Linköpings universitet; []
    Keywords : ;

    Abstract : The purpose of this thesis was to study the clinical implications of modern radiotherapy techniques for breast cancer treatment. This was investigated in several individual studies. READ MORE

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

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

    Abstract : 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. READ MORE

  5. 23. Out-of-field doses from proton therapy and doses from CBCT imaging : Risk of radiation-induced second cancer from modern radiotherapy

    Author : Oscar Ardenfors; Irena Gudowska; Alexandru Dasu; Cathrine Jonsson; Pawel Olko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The use of ionizing radiation for treatment of cancer diseases is continuously increasing as patient survival is improving and new treatment techniques are emerging. While this development is beneficial for curing primary tumors, concerns have been raised regarding the unwanted dose contribution to healthy tissues of patients and the associated risk of radiation-induced second cancer (RISC).

  6. 24. Pharmacological therapy of Helicobacter pylori infection

    Author : Peter Unge; Arnold Berstad; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The discovery of Helicobacter pylori (H. pylori) opened the doors to new insight and therapy for peptic ulcer disease. Earlier eradication treatment modalities based on bismuth compounds, with or without additional antimicrobials, were not well accepted mainly because of the, at least hypothetical, risks for neurological and/or renal side effects.

  7. 25. The microdosimetric variance-covariance method used for beam quality characterization in radiation protection and radiation therapy

    Author : Jan Erik Lillhök; Lennart Lindborg; Bernd Grosswendt; Stockholms universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ionizing radiation; radiation quality; radiation protection; radiation therapy; microdosimetry; nanodosimetry; variance-covariance method; Radiological physics; Radiofysik; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : Radiation quality is described by the RBE (relative biological effectiveness) that varies with the ionizing ability of the radiation. Microdosimetric quantities describe distributions of energy imparted to small volumes and can be related to RBE. READ MORE
