21. 201Thallium SPECT; accuracy in astrocytoma diagnosis and treatment evaluation
Sammanfattning : The aims of the studies included in this thesis were:• to investigate the reliability of 201thallium single photon emission computed tomography (201Tl SPECT) for preoperative diagnosis and histological staging of malignant astrocytomas in comparison with CT; • to develop a method for quantification of cerebral thallium uptake, and to evaluate the quantitative measurement in comparison with CT, for astrocytoma treatment follow-up purposes; • to compare quantitative 201Tl SPECT and proton magnetic resonance spectroscopy (1H-MRS) with conventional MR imaging for astrocytoma monitoring, and to evaluate associations between change of morphological tumour characteristics during treatment and changes of cerebral thallium uptake and metabolic ratios. Results and conclusions:• High 201Tl-index, calculated as a ratio comparing tumour uptake to uptake in the contralateral hemisphere, is an indicator of highly malignant astrocytoma. LÄS MER
22. Locally recurrent rectal cancer : aspects on management, surgery and outcome
Sammanfattning : Locally recurrent rectal cancer (LRRC) is a severe condition associated with a high morbidity and mortality, affecting about 150-200 people/year in Sweden. After improvements in management and treatment of primary rectal cancer (RC), including an amelioration and standardisation of surgical technique, improved preoperative staging, addition of preoperative radiotherapy (RT), implementation of multidisciplinary team conferences and postoperative surveillance programmes, the rate of LRRC has decreased dramatically from 30-40% to 5-15%.

23. Colon cancer : management and outcome in a Swedish population
Sammanfattning : Colon cancer is common in Sweden, with about 3500 new cases every year. Tumours of the colon and rectum are usually addressed as an entity. Great effort has been made to improve the outcome after rectal cancer treatment with subsequent improvement of survival. LÄS MER
24. FDG-PET in Cervical Cancer - Translational Studies
Sammanfattning : Cervical cancer is the second most common cancer in females. The treatment, based on clinical FIGO stage, carries a significant risk of side effects. FDG-PET enables non-invasive studies of glucose metabolism. Cancer cells show an increased glucose uptake and metabolism that can be visualised and further analysed. LÄS MER
25. Upper-tract urothelial carcinoma : diagnostics and prognostic factors
Sammanfattning : Upper-tract urothelial carcinoma (UTUC) is rare, constituting 5-10% of all urothelial cancers. Urothelial carcinoma of the bladder is a common disease and is more studied than UTUC. LÄS MER
