  2. 1. 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

  4. 2. Radiolabeled acetate PET in oncology imaging : studies on head and neck cancer, prostate cancer and normal distribution

    Author : Aijun Sun; Jens Sörensen; Silvia Johansson; Mikael Karlsson; Katrine Åhlström Riklund; Ingela Turesson; Heikki Minn; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; 11C-acetate; 18F-fluoroacetate; PET; head and neck cancer; staging; delineating tumor volume; clearance rate; perfusion; RT; treatment outcome; benign and malignant lymph node; prostate cancer; normal distribution; Oncology; Onkologi; onkologi; Oncology;

    Abstract : The use of positron emission tomography (PET) for imaging in oncology has grown rapidly in recent years. 2-[18F]-fluorodeoxyglucose (FDG) is the most common tracer of PET, although drawbacks exist. READ MORE

  5. 3. Head and Neck Cancer: Studies on microvessel density, radiation response and FDG PET

    Author : Eva Brun; Bröstcancer-genetik; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. PET in the evaluation of head and neck cancer treatment - management of the neck

    Author : Johanna Sjövall; Lund näs- och halssjukdomar Öron-; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Head and neck cancer; positron emission tomography; radiotherapy; treatment evaluation;

    Abstract : The treatment for head and neck squamous cell carcinoma (HNSCC) is surgery or (chemo)radiotherapy +/- surgery. Side effects related to therapy are long lasting and adversely affects quality of life. READ MORE

  7. 5. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy

    Author : Caroline Olsson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dose and side effect data; dose-volume response; fractionation effect; LQ model; sequential two-phase radiotherapy; head and neck cancer; parotid gland; xerostomia; pelvic radiotherapy; gynecological cancer; pubic bone; pain; data integration; xerostomia;

    Abstract : Although modern radiation therapy techniques have the ability to conform the dose distribution of ionizing radiation tightly around the volume to be treated, unwanted irradiation to surrounding organs remains a problem. The probability of a side effect arising in the normal tissue of a patient after radiation therapy can be modelled by sigmoid mathematical functions known as normal tissue complication probability (NTCP) models.
