  2. 1. Modelling late toxicity in hypofractionated radiation therapy

    Author : Niclas Pettersson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Hypofractionation; normal tissue complication probability; modelling; linear-quadratic model; fractionation sensitivity; late toxicity; radiation-induced rib fracture; genitourinary toxicity; stereotactic body radiation therapy; high-dose-rate brachytherapy; multimodality radiation therapy; patient-reported outcomes; prostate cancer; nsclc;

    Abstract : In hypofractionated radiation therapy (RT), the treatment is delivered by few fractions with high doses per fraction. This is in contrast to conventionally fractionated RT where the total dose is delivered in many fractions with low doses per fraction. READ MORE

  4. 2. Radiobiological end-points for the theoretical evaluation of the effectiveness of carbon ions and photons in treating tumours with dynamic hypoxia

    Author : Antonovic Laura; Iuliana Toma-Dasu; Tatsuaki Kanai; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; OER; hypoxia; LOC; RCR; hypofractionation; SBRT; carbon ion; fractionation; TCP; SF; RCE; RBE; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : Tumours are characterised by unorganised vasculature, which often results in hypoxic regions. Hypoxia is a common cause for photon radiotherapy (RT) treatment failure, as hypoxic cells require up to 2-3 times higher doses compared to well-oxygenated cells for the same effect in terms of cell kill.

  5. 3. Hypofractionated conformal stereotactic radiotherapy in the treatment of AVMs and cerebral metastases

    Author : Peter Lindvall; Hans Bolander; Umeå universitet; []
    Keywords : arteriovenous malformations; brain metastases; hypofractionation; stereotactic radiotherapy; LINAC; embolisation; Clinical Neurophysiology; klinisk neurofysiologi;

    Abstract : Hypofractionated conformal stereotactic radiotherapy (HCSRT) has been used for the treatment of AVMs at the Umeå University Hospital since 1986. From this year and onwards an increasing number of patients with single or oligo brain metastases have also been treated using this technique. READ MORE

  6. 4. Epidermal Melanocyte Response to Radiotherapy

    Author : Per Fessé; Henrik Lindman; Ingela Turesson; Johan Ahlgren; Jan Nyman; Catharine West; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Melanocytes; fractionated radiotherapy; ΔNp63; MITF; PAX3; SOX10; p53; p21; BMI1; pRb; CXCR2; DNA-DSB; 53BP1; CXCR2;

    Abstract : Cutaneous interfollicular melanocytes protect the skin from UV-radiation (UVR), and their response to UVR is well established. To date, the response activated in melanocytes by repeated genotoxic insults from radiotherapy (RT) has not been explored. READ MORE
