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. Improving the therapeutic ratio of stereotactic radiosurgery and radiotherapy
Sammanfattning : New methods of high dose delivery, such as intensity modulated radiation therapy (IMRT), stereotactic radiation therapy (SRT) or stereotactic radiosurgery (SRS), hadron therapy, tomotherapy, etc., all make use of a few large fractions. LÄS MER
3. 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
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. Risk factors, surgical outcome, and quality of life in patients with cranial or spinal meningioma
Sammanfattning : Meningiomas comprise approximately 30-38% of all cranial tumours and represent the largest group of primary intracranial and intraspinal tumours. Gliomas, of any grade, account for approximately 28% and glioblastomas 15% of the cranial tumours, as comparison. LÄS MER
