4. 2. Cancer risks in Swedish pesticide applicators in agriculture, forestry and gardening : a toxicological and epidemiological approach

   Author : Jan Dich; Karolinska Institutet; Karolinska Institutet; []
   Keywords : pesticide applicators; cancer incidence; Hodgkin s disease; non-Hodgkin s lymphoma; soft tissue sarcoma; prostate cancer; pesticides; phenoxy acid herbicides; organochlorine insecticides; occupational exposure; protective equipment; smoking habits;

   Abstract : The aims of this thesis were (1) to study the cancer risks in Swedish pesticide applicators, which is one of the occupational groups that is most exposed to pesticides in Sweden. This could be done by utilizing a complete register kept by the Swedish Board of Agriculture which include 20,245 subjects with licenses issued between 1965 and 1976, for epidemiological studies.

5. 3. Optimizing microwave hyperthermia antenna systems

   Author : Pegah Takook; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; head and neck tumors.; wideband antenna; microwave hyperthermia; time reversal;

   Abstract : This thesis presents design and optimization of a microwave hyperthermia antenna system for treatment of head and neck cancer as well as brain cancer. Hyperthermia has shown the ability to enhance the performance of radiotherapy and chemotherapy in many clinical trials. READ MORE

6. 4. Dose Plan Optimization in HDR Brachytherapy using Penalties : Properties and Extensions

   Author : Åsa Holm; Torbjörn Larsson; Åsa Carlsson Tedgren; Göran Sporre; Linköpings universitet; []
   Keywords : NATURAL SCIENCES; NATURVETENSKAP; MATHEMATICS; MATEMATIK;

   Abstract : High dose-rate (HDR) brachytherapy is a specific type of radiotherapy used to treat tumours of for example the cervix, prostate, and breasts. In HDR brachytherapy applicators are implanted into or close to the tumour volume. A radioactive source is moved through these applicators and stops at certain positions, known as dwell points.

7. 5. Towards UWB microwave hyperthermia for brain cancer treatment

   Author : Massimiliano Zanoli; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; treatment planning; microwave hyperthermia; brain cancer;

   Abstract : Despite numerous clinical trials demonstrating that microwave hyperthermia is a powerful adjuvant modality in the treatment of cancers, there have been few instances where this method has been applied to brain tumors. The reason is a combination of anatomical and physiological factors in this site that require an extra degree of accuracy and control in the thermal dose delivery which current systems are not able to provide.
