  1. 1. Modeling of dose and sensitivity heterogeneities in radiation therapy

    Author : Kristin Wiklund; Bengt K. Lind; Iuliana Toma-Dasu; Marco Zaider; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo simulations; Tumor control probability; Modeling; Beam characterization; Medical Radiation Physics; medicinsk strålningsfysik;

    Abstract : The increased interest in the use of light ion therapy is due to the high dose conformity to the target and the dense energy deposition along the tracks resulting in increased relative biological effectiveness compared to conventional radiation therapy. In spite of the good clinical experience, fundamental research on the characteristics of the ion beams is still needed in order to be able to fully explore their use. READ MORE

  2. 2. Tumor radiosensitivity and proliferation as parameters for optimizing radiotherapy

    Author : Mattias Hedman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Radiotherapy is a widely used method to treat malignant tumors. However, the sensitivity to the treatment varies between tumors, and local tumor control is not always achieved. The balance between treatment success and the side effects of the treatment affords important information for developing treatment schedules at patient population level. READ MORE

  3. 3. Nasopharyngeal carcinoma: past, present and future directions

    Author : Zahra Taheri-Kadkhoda; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : Nasopharyngeal carcinoma; radiotherapy; side effects; 3DCRT; Intracavitary brachytherapy; IMRT; IMPT; LMP1; EGFR.; radiotherapy; side effects; 3DCRT; Intracavitary brachytherapy; IMRT; IMPT; LMP1; EGFR;

    Abstract : Nasopharyngeal carcinoma (NPC) is a rare disease in Sweden. The purpose of this thesis was to investigate the clinicopathological manifestations of the disease and its treatment outcomes in a cohort of Swedish NPC patients to identify key features for future improvements in patient care.

  4. 4. Dose painting : Can radiotherapy be improved with image driven dose-responses derived from retrospective radiotherapy data?

    Author : Eric Grönlund; Anders Ahnesjö; Silvia Johansson; Daniela Thorwarth; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiotherapy; functional imaging; dose painting; dose painting by numbers; robust optimization; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : The main aim of curative radiotherapy for cancer is to prescribe and deliver doses that eradicate the tumor and spare the normal healthy tissues. Radiotherapy is commonly performed by delivering a homogeneous radiation dose to the tumor. READ MORE

  5. 5. Improved dose response modeling for normal tissue damage and therapy optimization

    Author : Magdalena Adamus-Górka; Bengt K. Lind; Anders Brahme; Panayiotis Mavroidis; Randall K. Ten Haken; Stockholms universitet; []
    Keywords : Normal tissue complications; radiobiological models; dose-response; volume effect; spinal cord; effective FSU size; medicinsk strålningsfysik; Medical Radiation Physics;

    Abstract : The present thesis is focused on the development and application of dose response models for radiation therapy. Radiobiological models of tissue response to radiation are an integral part of the radiotherapeutic process and a powerful tool to optimize tumor control and minimize damage to healthy tissues for use in clinical trials.
