  2. 1. Desmoid tumors. New aspects on diagnostic procedures, treatment and outcome

    Author : Mikael Dalén; Göteborgs universitet; []
    Keywords : desmoid; fibromatosis; surgery; radiotherapy; chemotherapy; statistics; imaging; studies; cytology; biopsy; pathology;

    Abstract : Desmoid tumor (aggressive fibromatosis) is a rare, benign fibroblastic/myofibroblasticneoplasm that originates from musculoaponeurotic structures. It never metastasizes but locallygrows aggressively and infiltrates surrounding tissues. The treatment of choice has beensurgery. However, local recurrences are frequent. READ MORE

  4. 2. Key Data for the Reference and Relative Dosimetry of Radiotherapy and Diagnostic and Interventional Radiology Beams

    Author : Hamza Benmakhlouf; Pedro Andreo; Klemens Zink; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Backscatter factors; Diagnostic radiology dosimetry; Mass energy-absorption coefficients; Monte Carlo; Output correction factors; Radiotherapy dosimetry; Reference dosimetry; Relative dosimetry; Small photon fields; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Accurate dosimetry is a fundamental requirement for the safe and efficient use of radiation in medical applications. International Codes of Practice, such as IAEA TRS-398 (2000) for radiotherapy beams and IAEA TRS-457 (2007) for diagnostic radiology beams, provide the necessary formulation for reference and relative dosimetry and the data required for their implementation.

  5. 3. Rectal cancer : aspects on radiotherapy, androgens and body composition

    Author : Christian Buchli; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Rectal cancer is diagnosed among 1200 men in Sweden every year. Current treatment for local and regional disease implies surgical resection of the rectum often in combination with preoperative radiotherapy (RT). READ MORE

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

    Author : Oscar Ardenfors; Irena Gudowska; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.

  7. 5. Immediate breast reconstruction : patient information, regional variations and effects of radiotherapy

    Author : Carl Axel Frisell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The type of surgical treatment in breast cancer shows strong regional variation. The aim of studies I-III was to specifically investigate causes of the disparity in breast conservation and immediate breast reconstruction (IBR) rates in the six Swedish healthcare regions. READ MORE
