1. 16. Ensuring the intended volume is given the intended absorbed dose in radiotherapy: Managing geometric variations and treatment hazards

   Författare :Ola Holmberg; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medical instrumentation; tomography; radiology; Clinical physics; safety; risk; hazard; organ motion; set-up; margins; volume definition; radiotherapy; accuracy; Klinisk fysiologi; radiologi; tomografi; medicinsk instrumentering; Radiopharmaceutical technology; Radiofarmaceutisk teknik;

   Sammanfattning : Methods for ensuring that the intended volume receives the intended absorbed dose in radiotherapy have been investigated. In order to optimise radiation treatment of cancer, geometric variations in the treatment chain need to be controlled. Furthermore, hazards potentially leading to unintended irradiation need to be controlled. LÄS MER

3. 17. Quality Assurance in Radiotherapy - Development and evaluation of new tools for improved patient safety

   Författare :Fredrik Nordström; Malmö Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; monitor unit verification; in vivo dosimetry; real-time verification; gel dosimetry; 4D dosimetry; IMRT; VMAT; data integrity; radiotherapy; Quality assurance;

   Sammanfattning : Preparation for radiotherapy is a complex procedure that involves many different technologies and groups of professionals. The rapid development and introduction of new technologies throughout the last decade have made it possible to deliver highly conformal, individually-shaped dose distributions with high accuracy.

4. 18. Head and Neck Cancer: Studies on microvessel density, radiation response and FDG PET

   Författare :Eva Brun; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; positron emission tomography PET ; 2-18 fluoro deoxy glucose FDG ; radiotherapy; microvessel density; Head and neck cancer; therapy response; Cytology; oncology; cancerology; Cytologi; onkologi; cancer;

   Sammanfattning : Treatment options of head and neck squamous cell carcinoma (HNSCC) usually include combinations of radiotherapy and surgery, and in some cases addition of chemotherapy. In locally advanced cases cure rates are low. Current prognostic factors cannot foresee the outcome for the individual patient. LÄS MER

5. 19. Radiotherapy in Early Breast Cancer

   Författare :Fredrika Killander; Bröstcancer-genetik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; pentoxifylline; cyclophosphamide; tamoxifen; side effects; randomised trial; Breast cancer; radiotherapy;

   Sammanfattning : Radiotherapy (RT) after mastectomy has been part of the treatment for early breast cancer since the 1940s. The treatment reduces the risk of loco-regional recurrences, but implies risk of late side effects that can begin decades after RT. LÄS MER

7. 20. p73 in colorectal cancer

   Författare :Daniella Pfeifer; Sun Xiao-Feng; Vladimir Bykov; Linköpings universitet; []
   Nyckelord :MEDICINE; MEDICIN;

   Sammanfattning : Colorectal cancer (CRC) is the third most common cancer in the world, with about 5000 new cases in Sweden every year. CRC is caused by mutation (inherited or acquired) in genes, by gene variants and changed expression of proteins. The primary way to achieve a curative result for CRC is to remove the tumor by surgery. LÄS MER
