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

    Author : Gracinda Mondlane; Albert Siegbahn; Michael Gubanski; Iuliana Toma-Dasu; Crister Ceberg; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; 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;

    Abstract : 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. READ MORE

  3. 3. Beyond treatment? : widening the approach to alcohol problems and solutions

    Author : Jan Blomqvist; Douglas Cameron; Stockholms universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social work; Socialt arbete; Social Work; socialt arbete;

    Abstract : The dissertation includes four different studies which, from different points of departure, aim to illuminate problems and prospects of social work with alcohol problems in contemporary Sweden.Paper 1 analyses the historical succession of predominant public images of, and societal responses to, alcohol problems in Sweden during the past century.

  4. 4. Probabilistic treatment planning based on dose coverage : How to quantify and minimize the effects of geometric uncertainties in radiotherapy

    Author : David Tilly; Anders Ahnesjö; Erik Grusell; Uwe Oelfke; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Radiotherapy; treatment simulation; probabilistic planning; dose calculation; probabilistic optimization; statistical shape model; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Traditionally, uncertainties are handled by expanding the irradiated volume to ensure target dose coverage to a certain probability. The uncertainties arise from e.g. the uncertainty in positioning of the patient at every fraction, organ motion and in defining the region of interests on the acquired images. READ MORE

  5. 5. Comparative treatment planning in external radiotherapy of malignant tumours : Potential gains using protons

    Author : Ulf Isacsson; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Breast cancer; comparative treatment; Ewing sarcoma; oesophageal cancer; proton therapy; radiotherapy; rectal cancer; treatment planning algorithms; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Abstract : It is well known that protons have physical characteristics superior to conventional radiation qualities in external beam radiotherapy. The primary aim of this work is to determine if the physical advantages also may lead to clinical advantages. READ MORE
