1. Contouring & planning variability in stereotactic radiosurgery : How to assess and address the weakest link in stereotactic radiosurgery?
Sammanfattning : The use of stereotactic radiosurgery (SRS) employing one or a few fractions of high doses of radiation has continuously increased due to the technical development in dose delivery and morphological and functional imaging. As the target volume in SRS is usually defined without margins, the treatment success critically depends on accurate definition and contouring of the target volume and organs at risk (OARs) which are commonly situated in the proximity of the target making their precise delineation particularly important in order to limit possible normal tissue complications.

2. Treatment selection in metastatic renal cell carcinoma : Towards an individualised approach
Sammanfattning : Renal cell carcinoma (RCC), a common malignancy worldwide, affects 1200 new patients yearly in Sweden. Metastatic RCC (mRCC) develops in one in three and is commonly incurable. Clear cell histology dominates followed by papillary histology. LÄS MER
3. Gamma knife surgery of cerebral arteriovenous malformations
Sammanfattning : Aims of the study: to define and quantify parameters of importance for the treatment result in Gamma Knife (GK) surgery of arteriovenous malformations (AVM). To determine the natural course of AVM in order to calculate the impact of the GK treatment on the latency period between treatment and obliteration. LÄS MER
4. Contouring variability in radiosurgery - dosimetric and radiobiological implications
Sammanfattning : The use of Stereotactic Radiation Therapy (SRT) employing one large fraction of radiation, as in stereotactic radiosurgery (SRS), or few fractions of high doses, has continuously increased due to the technical development and the progress in dose delivery complemented by the positive clinical experience. The success of stereotactic radiation therapy depends on many clinical, dosimetric and radiobiological factors. LÄS MER
5. Volume determination and predictive models in the management of cerebral arteriovenous malformations
Sammanfattning : Cerebral arteriovenous malformations (AVMs) entail a high cumulative risk of severe neurological symptoms and are usually treated with surgery, radiosurgery, embolisation or combinations thereof. There are well supported models to predict the outcome of radiosurgery, but similar models do not exist for surgery or embolisation. LÄS MER
