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

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

   Sammanfattning : 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. LÄS MER

3. 7. PET and MR imaging in prostate cancer

   Författare :Kristina Sandgren; Tufve Nyholm; Joakim Jonsson; Camilla Thellenberg-Karlsson; Lennart Blomqvist; Heidi Lyng; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PET; PSMA; MRI; PET MRI; imaging; prostate cancer; intraprostatic tumour detection; radiofysik; radiation physics;

   Sammanfattning : The current risk assessment of prostate cancer (PC) relies on histopathological samples from biopsies and clinical variables such as prostate-specific antigen (PSA). However, this comes with uncertainties and in some cases it can be challenging to separate patients who would benefit from radical treatment and those who would not. LÄS MER

4. 8. Relative biological effectiveness in proton therapy: accounting for variability and uncertainties

   Författare :Jakob Ödén; Iuliana Toma-Dasu; Kjell Eriksson; Radhe Mohan; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; proton therapy; relative biological effectiveness; linear energy transfer; proton track-end optimisation; radiation-induced toxicity; Medical Radiation Physics; medicinsk strålningsfysik;

   Sammanfattning : Radiation therapy is widely used for treatments of malignant diseases. The search for the optimal radiation treatment approach for a specific case is a complex task, ultimately seeking to maximise the tumour control probability (TCP) while minimising the normal tissue complication probability (NTCP).

5. 9. Optimising External Beam Radiotherapy for Prostate Cancer. Advances in Treatment Planning

   Författare :Vilberg Jóhannesson; Systemisk strålterapi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

   Sammanfattning : BackgroundRadiotherapy (RT) is an effective treatment option for prostate cancer (PCa). The evolution of new treatment planning techniques, advanced imaging and accelerator design has enabled precise treatment delivery. LÄS MER

7. 10. Promoting physical activity during and after curative cancer treatment : Assessment, experiences and effect of behaviour change support

   Författare :Anne-Sophie Mazzoni; Ingrid Demmelmaier; Karin Nordin; Sveinung Berntsen; Maria Hagströmer; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adherence; Behavioural medicine; Exercise; Incentives; Maintenance; Oncology; Caring Sciences; Vårdvetenskap;

   Sammanfattning : Aims:The overall aim of this thesis was to increase knowledge about the promotion of physical activity (PA) in patients during and after curative cancer treatment. Methods: Study I investigated agreement between a 7-day diary and the SenseWear Armband mini (SWA) when assessing PA and sedentary time in 65 participants with breast cancer. LÄS MER
