  2. 6. Verification of dose calculations in radiotherapy

    Author : Tufve Nyholm; Mikael Karlsson; Ben Mijnheer; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; dose calculation; quality control; pencil kernel; Radiological physics; Radiofysik;

    Abstract : External radiotherapy is a common treatment technique for cancer. It has been shown that radiation therapy is a both clinically and economically effective treatment for many types of cancer, even though the equipment is expensive. The technology is in constant evolution and more and more sophisticated and complex techniques are introduced. READ MORE

  4. 7. Radiotherapy for head and neck cancer : costs and benefits of time, dose and volume

    Author : Karin Söderström; Björn Zackrisson; Werner Dubrowsky; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiotherapy; head and neck cancer; adjuvant treatment; accelerated fractionation; biomedicinsk strålningsvetenskap; Biomedical Radiation Science;

    Abstract : Background In the treatment of head and neck cancers (HNCs), radiotherapy (RT) has the advantage of organ preservation compared to surgery. However, treatment toxicities associated with RT can affect important functions for everyday life, both in the acute and late stage. READ MORE

  5. 8. Treatment selection in metastatic renal cell carcinoma : Towards an individualised approach

    Author : Maria Stenman; Magnus Lindskog; Ulrika Harmenberg; Tim Eisen; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rcc; renal cell carcinoma; kidney cancer; stereotactic radiotherapy; srt; stereotactic body radiotherapy; sbrt; gamma knife radiosurgery; gkrs; stereotactic radiosurgery; srs; radiotherapy; overall survival; prognostic factor; papillary; Oncology; Onkologi;

    Abstract : Renal cell carcinoma (RCC), a common malignancy worldwide, affects 1200 new patients yearly in Sweden. Metastatic RCC (mRCC) develops in one in three and is commonly incurable. Clear cell histology dominates followed by papillary histology. READ MORE

  6. 9. Clinical application of intensity and energy modulated radiotherapy with photon and electron beams

    Author : Xiangkui Mu; Björn Zackrisson; Mikael Karlsson; Thomas Björk-Eriksson; Erik Blomquist; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Radiotherapy; IMXT; IMET; IMPT; proton beams; electron beams; treatment planning; cancer induction; side-effects; fraction time; intensity modulated radiotherapy; Onkologi; Oncology; Onkologi; Oncology; onkologi;

    Abstract : In modern, advanced radiotherapy (e.g. intensity modulated photon radiotherapy, IMXT) the delivery time for each fraction becomes prolonged to 10-20 minutes compared with the conventional, commonly 2-5 minutes. The biological effect of this prolongation is not fully known. READ MORE

  7. 10. Dosimetric effects of breathing motion in radiotherapy

    Author : Anneli Edvardsson; Lund Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; radiotherapy; breathing motion; DIBH; interplay effects; VMAT; proton therapy; breast cancer; Hodgkin’s lymphoma; liver; dosimetry; treatment planning; medical physics;

    Abstract : The goal of radiotherapy is to deliver a homogeneous high dose of radiation to a tumour while minimising the dose to the surrounding healthy tissue. To achieve this, increasingly advanced treatment techniques, such as volumetric modulated arc therapy (VMAT) and proton therapy, have been developed. READ MORE
