1. Radiation Oncology Data and Modelling Side Effects after Radiation Therapy
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.

2. Towards eliminating pelvic bone pain after radiation therapy among long-term gynecological cancer survivors
Abstract : Aim: To investigate the prevalence of self-reported symptoms after pelvic radiation therapy among long-term gynecological cancer survivors, with special focus on pelvic bone pain, how it affects the daily life of the women and the relationship to absorbed doses. Methods: In an unselected, population-based study, gynecological cancer survivors from the Gothenburg and Stockholm regions, treated with pelvic radiation therapy between 1991 and 2003, were compared with a non-radiation-treated control population.

3. Towards better quality of life after radiation therapy by improved response modeling
Abstract : Background: To improve the quality of life of radiotherapy cancer survivors we need to improve our knowledge of the dose, volume and time-response relations of radiotherapy induced late effects. Aims: The aim of the thesis was to investigate predictors for normal-tissue complications of head and neck, and gynecological radiotherapy using response modeling. READ MORE

4. Predicting Normal Tissue Complications after External Beam Radiation Therapy
Abstract : Although modern external beam radiation (EBRT) therapy has the ability to conform the dose tightly around the volume to be treated, unwanted irradiation to surrounding normal tissue is still a problem. The probability of a side effect arising in normal tissue after EBRT is commonly modelled by an s-shaped dose-volume response curve where dose or volume are plotted against response (i. READ MORE

5. Optimizing postoperative radiation therapy in prostate cancer: focus on side-effects, practical implementation and dose distribution
Abstract : Optimizing postoperative radiotherapy in prostate cancer: focus on side effects, practical implementation and dose distribution Karin Braide, MD Department of Urology, Institute of Clincal Sciences Sahlgrenska Academy, University of Gothenburg, Gothenburg, Sweden ABSTRACT We analyzed side-effects, pre-treatment bladder preparations and dose distribution to the rectum in four different cohorts of patients, treated with postoperative radiotherapy (PRT) in prostate cancer. Side-effects according to a self-reporting survey revealed rectal bleeding as a main result in a follow up time of 6. READ MORE
