2. 1. Mathematical Optimization of HDR Brachytherapy

   Author : Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Jeroen Beliën; Linköpings universitet; []
   Keywords : ;

   Abstract : One out of eight deaths throughout the world is due to cancer. Developing new treatments and improving existing treatments is hence of major importance. In this thesis we have studied how mathematical optimization can be used to improve an existing treatment method: high-dose-rate (HDR) brachytherapy. READ MORE

4. 2. Adjuvant treatments to prevent local reurrence after breast-conserving surgery for early breast cancer : radiation, endocrine- or brachytherapy

   Author : Åsa Wickberg; Göran Liljegren; Johan Ahlgren; Roger Olofsson Bagge; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Breast-conserving surgery; radiotherapy; endocrine therapy; intraoperative brachytherapy;

   Abstract : Radiotherapy after breast-conserving surgery due to breast cancer is an established treatment, known to reduce the incidence of recurrence and even death from the disease. However some women are over-treated with sometimes serious adverse effects. De-escalating the treatment and find alternative adjuvant methods are becoming an important issue. READ MORE

5. 3. Dosimetry in brachytherapy : application of the Monte Carlo method to single source dosimetry and use of correlated sampling for accelerated dose calculations

   Author : Håkan Hedtjärn; David Rogers; Linköpings universitet; []
   Keywords : MEDICINE; MEDICIN;

   Abstract : Three issues related to brachytherapy dosimetry are addressed in this thesis. (1) The prospect of using Compton scattering to measure energy spectra from a high dose-rate (HDR) 192Ir source is discussed and a Compton spectrometer evaluated. READ MORE

6. 4. Dose Escalation with High Dose Rate Brachytherapy or Protons in Curative Radiotherapy of Prostate Cancer

   Author : Lennart Åström; Lars Holmberg; Gunilla Enblad; Henrik Grönberg; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Prostate cancer; radiotherapy; brachytherapy; high dose rate; protons; PSA bounce;

   Abstract : The aim of the thesis was to study the outcome and side effects after dose-escalated radiotherapy with high dose rate brachytherapy (HDR-BT) or proton beam therapy (PBT) boost in prostate cancer.The first cohorts of men in Sweden treated with either HDR-BT or PBT in combination with conventional photon beam therapy (2 Gray (Gy) fractions to 50 Gy) were analysed.

7. 5. Long-term outcome research on PDR brachytherapy with focus on breast, base of tongue and lip cancer

   Author : Bengt Johansson; Jan Persliden; Jan Nyman; Örebro universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDR; brachytherapy; outcome; partial breast irradiation; base of tongue cancer; lip cancer; quality of life; dosimetry.; Oncology; Onkologi; Surgery; Kirurgi; Onkologi; Oncology; Surgery; Kirurgi;

   Abstract : Brachytherapy (BT) with continuous low dose rate (LDR) has been used for 100 years and is considered as the radiotherapy method able to deliver a dose in the shortest time with high efficacy and low risk of side effects. The drawbacks are need for patient isolation and radiation exposure of the staff during the treatment. READ MORE
