1. 6. Cognitive Deficits Reflecting Diffuse and Focal Brain Lesions Caused by Slow Growing Brain Tumors - Low-grade Gliomas

   Författare :Lena Ek; Ove Almkvist; Anja Smits; Hans Samuelsson; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Cognition; low-grade glioma; brain tumor; diffuse brain injury; neuropsychological tests; Psychology; Psykologi; Psychology; psykologi;

   Sammanfattning : The overall purpose was to characterize the impact that low-grade glioma (LGG) – a type of slowly growing brain tumor – has on cognitive functions. Paper I was an in-depth analysis of cognitive dysfunction of patients with histological proven LGG. LÄS MER

3. 7. Genotype-phenotype studies in brain tumors

   Författare :Soma Ghasimi; Ulrika Andersson; Beatrice Melin; Roger Henriksson; Clemens Dirven; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; Meningioma; SNP; IHC; FISH; LRIG2; EGF; EGFR; ERBB2; ER; CDKN2A B; IDH1; onkologi; Oncology;

   Sammanfattning : Meningioma and glioma are the most common primary brain tumors, but their etiologies are largely unknown. Although meningioma is usually benign, their intracranial location can lead to lethal consequences, and despite progress in surgery, radiotherapy, and chemotherapy the prognosis for patients with glioma remains poor.

4. 8. Fluorescence Guided Resection of Brain Tumors : Evaluation of a Hand-held Spectroscopic Probe

   Författare :Johan Richter; Karin Wårdell; Jan Hillman; Peter Siesjö; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Malignant gliomas grow infiltrative in the brain and can therefore not be completely removed by neurosurgical means. However, for an optimized oncological treatment it has proven useful to resect as much as possible of tumor. The identification of the tumor in the marginal zone is difficult but crucial. LÄS MER

5. 9. Applications of diffusion MRI: Tensor-valued encoding, time-dependent diffusion, and histological validation

   Författare :Jan Brabec; Lund Medicinsk strålningsfysik; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; diffusion MRI; meningioma; glioma; brain tumors; intracranial tumors; undulations; restricted diffusion; time dependence; spherical b-tensor encoding; linear b-tensor encoding; histogram analysis; anisotropic kurtosis; isotropic kurtosis; hyperintensity; conspicuity; white matter; detection; diffusion spectrum; consistency; type; grade; axon diameter; axonal trajectories; Fysicumarkivet A:2022:Brabec;

   Sammanfattning : Diffusion MRI (dMRI) sensitizes the MR signal to the diffusion of water molecules at the microscopic level and thereby non-invasively probes tissue microstructure. This is relevant when determining biological properties of tissues, for example, cancer type and its malignancy. LÄS MER

7. 10. Novel methods of malignant brain tumor treatment utilizing the tumor microenvironment

   Författare :Jan Kopecky; Neurokirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Brain tumors; Glioblastoma; Medulloblastoma; Convection-enhanced delivery; Antisecretory factor; AF16; Salovum; Macrophages; Immunology; Cancer; CD24; Siglec10; Antiphagocytic signaling;

   Sammanfattning : Malignant brain tumors constitute a disaster in the lives of patients, either in the form of extremely low survival in glioblastoma, or the serious long-term adverse effects of therapy in medulloblastoma. These two tumor types represent the most common malignant brain entities in adults and children, respectively. LÄS MER
