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

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

   Sammanfattning : 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).

3. 2. Comparative Treatment Planning in Radiotherapy and Clinical Impact of Proton Relative Biological Effectiveness

   Författare :Jonas Johansson; Bengt Glimelius; Anders Montelius; Tony Lomax; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; Comparative studies; Breast cancer; hypopharyngeal cancer; rectal cancer; Proton RBE; Onkologi; Oncology; Onkologi;

   Sammanfattning : The development of new irradiation techniques is presently a very active field of research with increased availability of more sophisticated modalities such as intensity modulated photons (IMRT), protons and light ions. The primary aim of this work is to evaluate if the dose-distributions using IMRT and protons contribute to clinical advantages. LÄS MER

4. 3. 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

5. 4. Secondary doses to healthy tissues from radiotherapy and modern imaging techniques

   Författare :Oscar Ardenfors; Irena Gudowska; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The use of ionizing radiation for treatment of cancer diseases is continuously increasing giving rise to several new questions and concerns. One of the most important aspects of this is the associated dose imparted to healthy tissues. This unwanted dose contribution is a result of both radiotherapy procedures and diagnostic imaging.
